Unemployment and inflation

The rise in energy prices reduces the productivity of capital per worker. This causes sf(k) to shift down from sfl(k) to sf2(k). The result is a decline in steady-state k. Steady-state consumption per worker falls for two reasons: (1) Each unit of capital has a lower productivity, and (2) steady-state k is reduced. population growth rate permanently increased due to increased immigration Immigration raises n from nl to n2. The rise in n lowers steady-state k, leading toa lower steady-state consumption per worker. c.A temporary rise in s has no effect on the steady-state equilibrium. . The increase in the labor force participation rate does not affect the growth rate of the labor force, so there is no impact on the steady-state capital-labor ratio or on consumption per worker. However, because a larger fraction of the population is working, consumption per person increases. Question 4 How would each of the following affect the national saving, investment the current account balance an d the real interest rate in the large economy (a) The home countrys saving curve shifts to the right, from Sl to S2.The real world interest rate falls, so that the current account surplus in the home country equals the current ccount deficit in the foreign country. National S rises, I rises, CA rises, rw falls. (b) The foreign countrys saving curve shifts to the right, from Sl For to S2For. The real world interest rate must fall, so the current account surplus in the foreign country equals the current account deficit in the home country. National S falls, I rises, CA falls, rw falls.C The foreign countrys saving curve shifts to the left, from Sl For to S2For. The real world interest rate must rise, so the current account deficit in the foreign country equals the current account surplus in the home country. National S rises, I falls, CA ises, rw rises. (c) If Ricardian equivalence holds, there is no effect. If Ricardian equivalence does not hold, then the result is the same as in par t (b), as the toreign count saving curve shifts to the right.That is because all else equal, higher taxes increase government saving more than they reduce private saving. Question 3. Explain how each of the following transaction would enter the Bahamas Question 3 a Income receipt from abroad: credit entry in current account. b Import of assets: debit entry in capital and financial account. (c Import of services: debit entry in current account. (d Increase in foreign ownership of U. S. assets: credit entry in capital and financial account. Question2.Assume (a) Desired consumption declines as the real interest rate rises because the higher return to saving encourages higher saving; desired investment declines as the real interest rate rises becauses the user cost of capital is higher, reducing the desired capital stock, and thus investment. (b) Recall that Sd = Y -Cd – G, so Sd = 9000 -Cd – ld 2 6100 1 500 3 1400 1 ooo 4 5900 1300 1100 9200 5 1200 6 5700 equilibrium. Giv en Y 9000, the equili brium condition holds only at r = 5%. Atr = 5% it is also true that Sd = = 1200. Question 1Keynesians and classicals differ sharply in their beliefs about how long it takes the economy to reach a long-run equilibrium. Classical economists believe that prices adjust rapidly (within a few months) to restore equilibrium in the face of a shock, while Keynesians believe that prices adjust slowly, taking perhaps several years. Because of the time it takes for the economy's equilibrium to be restored, Keynesians see an important role for the government in fighting recessions. But because classicals believe that equilibrium is restored quickly, there's no need for government policy to fght recessions.Since classicals think equilibrium is restored quickly in the face of shocks, aggregate demand shocks can't cause recessions, since they can't affect output for very long. So classical economists think recessions are caused by aggregate supply shocks. Keynesians, however, think that both aggregate demand and aggregate supply shocks are capable of causing recessions. Question 8 Growth that is â€Å"too rapid† most likely refers to a situation in which the aggregate demand curve has shifted to the right and, in the short run, intersects the SRAS curve at a level of output that's greater than the full-employment level of output.This situation is associated with inflation because, in the long run, prices will rise, shifting the SRAS curve up to intersect with the LRAS and AD curves. The shock that is implicitly assumed to be hitting the economy is an aggregate demand shock, since that's the only shock that increases output in the short run and inflation in the long run. Question 10 The temporary increase in government purchases causes an income effect that increases workers' labor supply. This results in an increase in the full-employment level of output from FEI to FE2 in Figure 10. 10.The increase in government urchases also shifts the IS curve up and to the right from ISI to IS2, as it reduces national saving. Assuming that the shift up of the IS curve is so large that it intersects the LM curve to the right of the FE line, the price level must rise to get back to equilibrium at full employment, by shifting the LM curve up and to the left from LMI to LM2. The result is an increase in output and the real interest rate. figure 10. 11 shows the impact on the labor market. Labor supply shifts from NSI to NS2, leading to a decline in the real wage and a rise in employment.Average labor productivity declines, since employment rises while capita ixed. Investmentdeclines, since the real interest rate rises. To summarize, in response to a temporary increase in government purchases, output, the real interest rate, the price level, and employment rise, while average labor productivity and investment decline. (a) The business cycle fact is that employment is procyclical. The model is consistent with this fact, since employment rises when government purchases rise, causing output to rise. (b) The business cycle fact is that the real wage is mildly procyclical.The model is inconsistent with this fact, since it shows a decline in the real wage when government purchases rise and c) The business cycle fact is that average labor productivity is output rises. procyclical. The model is inconsistent with this fact, since it shows a decline in average labor productivity when government purchases rise and output rises. (d) The business cycle fact is that investment is procyclical. The model is not consistent with this fact, as investment falls when government purchases rise and output rises. (e) The business cycle fact is that the price level is procyclical.The model is consistent with this fact, as the price level rises when government purchases increase and output increases. Question 6 and 7 (a) An increase in government purchases reduces national saving, causing the real interest rate to rise for a fixed level of incom e. If the real interest rate is higher, then real money demand will be lower. The price level must rise. The result is that output is unchanged, the real interest rate increases, and the price level increases. 6 (b) 7aWhen expected inflation falls, real money demand increases.There is no effect on employment, saving or investment, so output and the real interest rate remain unchanged. With higher real money demand and an unchanged nominal money supply, the equilibrium price level must decline. b) When labor supply rises, full- employment output increases. Higher output means higher income, so saving will increase. More saving means the real interest rate will decline. Both higher output and a lower real interest rate increase real money demand. Higher money demand with a constant money supply means the price level must decline. 17 c When the interest rate paid on money increases, real money demand rises. That is because the cost of holding money falls. With no effect on employment o r saving and investment, output and the real interest rate remain unchanged. With higher real money demand and an unchanged nominal money supply, the quilibrium price level must decline. Question 11 and 12 In Figures 11 . 17-11. 20, point A is the starting point, point B shows the short-run equilibrium after the change, and point C shows the long-run equilibrium after the change. (a) In Figure 11. 7, when banks pay a higher interest rate on checking accounts, the demand for money rises, shifting the LM curve up and to the left from LMI to LM2 in Figure 11 . 17(a). As a result, the AD curve shifts down and to the 2 in Figure ) The new snort-run equilibrium occurs at point B, where output is lower, the real interest rate is higher, employment is lower, and the price level is unchanged. In the long run, the price level decreases to shift the LM curve from LM2 to LM3, which is the same as LMI, to restore equilibrium at point C. As a result, the short-run aggregate supply curve shifts do wn from SRASI to SRAS2.At the new equilibrium, compared to the starting point, output is the same, the real interest rate is the same, employment is the same, and the price level is lower. Figure 11. 17 (b) In Figure 11. 18, the introduction of credit cards reduces the demand for money†shifting the LM curve down and to the right from LMI to LM2 in Figure 11 . 18(a). As a result, the AD curve shifts from ADI to AD2 in Figure 11. 8(b). The new short-run equilibrium occurs at point B, where output is higher, the real interest rate is lower, employment is higher, and the price level is unchanged.In the long run, the price level increases to shift the LM curve from LM2 to LM3, which is the same as LMI, to restore equilibrium at point C. As a result, the short-run aggregate supply curve shifts up from SRASI to SRAS2. At the new equilibrium, compared to the starting point, output is the same, the real interest rate is the same, employment is the same, and the price level is higher. F igure 11. 18 (c) In Figure 11. 9, the reduction in agricultural output shifts the FE curve to the left from FEI to FE2, and shifts the LRAS line from LRASI to LRAS2.The rise in agricultural prices increases the price level, so the short-run aggregate supply curve shifts up from SRASI to SRAS2. Also, the rise in the price level shifts the LM curve up and to the left from LMI to LM2. The short-run equilibrium is at point B, assuming that the LM curve shifts so much that it intersects the IS curve to the left of the FE line. At point B, compared to the starting point, output is lower, the real interest rate is higher, employment is lower, and the price level is higher. Figure 11. 19 If the water shortage persists, a new long-run equilibrium occurs at point C.To get to this equilibrium, the price level must decline, shifting the LM curve from LM2 to LM3, and the short-run aggregate supply curve from SRAS2 to SRAS3. Relative to point B, the new equilibrium has a higher output level, a lo wer real interest rate, higher employment, and a lower price level. (Relative to the initial equilibrium at point A, output and employment are lower, and the real interest rate and the price level are higher.

Professional Studies Essay

The word ethics originates from the Greek term ethos. Ethos means customs, habitual usage, conduct, and character. The study of ethics has led to establishing key nursing principles such as, autonomy, beneficence, nonmaleficence, justice, veracity, confidentiality, accountability and fidelity. These key principles help nurses deal with ethical or legal dilemmas. Ethics help by identifying standards, create a framework for ethical dilemmas and maintain human rights, and ethical values. Ethics help to make nurse practice safe, but also promote a positive outcome for the patient. This essay explores and identifys legal and ethical issues, from a case study, that nurses are faced with every day. The Code of Ethics for Nurses in Australia was first developed in 1993 under the auspices of the Australian Nursing Council Inc. , Royal College of Nursing, Australia and the Australian Nursing Federation. In 2000 these peak organisations agreed to undertake a joint project to review the Code of Ethics. The Code of Ethics is supported by the Code of Professional Conduct for Nurses in Australia. While the Code of Ethics focuses on the ethics and ideals of the profession, the Code of Professional Conduct identifies the minimum requirements for practice in the profession, and focuses on the clarification of professional misconduct and unprofessional conduct. The two Codes, together with published practice standards, provide a framework for nursing. Individuals have the right to make decisions related to their own health care, based on accurate and complete information given by health care providers. Nurses must be satisfied that they have the person’s consent for any care or treatment they are providing. If individuals are not able to provide consent for themselves, nurses have a role in ensuring that valid consent is obtained from the appropriate substitute decision- maker. Nurses have a responsibility to inform people about the nursing care that is available to them, and people are entitled morally to accept or reject such care. Nurses have a responsibility to respect the decisions made by each individual. his principle states that an ethical theory should allow people to reign over themselves and to be able to make decisions that apply to their lives. This means that people should have control over their lives as much as possible because they are the only people who completely understand their chosen type of lifestyle. Each man deserves respect because only he has had those exact life experiences and understands his emotions, motivations and body in such an intimate manner. In essence, this ethical principle is an extension of the ethical principle of beneficence because a person who is independent usually prefers to have control over his life experiences in order to obtain the lifestyle that he enjoys The principle of beneficence guides the ethical theory to do what is good. This priority to â€Å"do good† makes an ethical perspective and possible solution to an ethical dilemma acceptable. This principle is also related to the principle of utility, which states that we should attempt generate the largest ratio of good over evil possible in the world (2). This principle stipulates that ethical theories should strive to achieve the greatest amount of good because people benefit from the most good. This principle is mainly associated with the utilitarian ethical theory found in the following section of this paper. An example of â€Å"doing good† is found in the practice of medicine in which the health of an individual is bettered by treatment from a physician (1,2).

MARKETING OF LONDON EYE Essay Example | Topics and Well Written Essays - 1750 words

MARKETING OF LONDON EYE - Essay Example All these questions can be answered with a help of marketing research that is irreplaceable in business strategy. If we try to look at the modern economic sector more attentively, we can state that indeed marketing is everywhere. It is rather hard to imagine a firm that proposes new product to the market without using any marketing principles and after all successfully operates in the conditions of free competition. Today wide range of goods and services compel to care about advertising elements more meticulously, making any attempt to attract consumers’ attention and persuade them to purchase a product of your brand. Only detailed analysis of the market situation is able to lead entrepreneur to the right direction. In this respect, it is vital to use marketing strategies that contain several interconnected elements and elaborate clear step-by-step scheme concerning each of them. Historically marketing appeared long time ago. In 1960 American professor and marketer, McCarthy, has formulated the concept of Marketing Mix, which consists of four elements called simply Four Ps. It is fair to admit that each factor of the mentioned concept is vital for the life circle of the product, because consequences of one element are able to influence on the work of others, which in own turn affect financial results of the company’s performance. Therefore nowadays small and large enterprises assign a big role to the marketing department, which conducts marketing surveys, researches, analysis and creates stimulus for the work of other departments. For further and deeper understanding of the Marketing Mix principles, the London Eye has been chosen as an example of favorable marketing performance. With a help of information about observation wheel’s performance it is easy to see the Four Ps on stream and draw up recommendations concerning a future development of the company. As it has been already mentioned before, all elements

Question 2 Essay Example | Topics and Well Written Essays - 750 words

Question 2 - Essay Example It is the interest which the insured stands to lose if the risk attaches. The risk that is therefore attached to every passenger in a public means of transport is varied to some extent (Soule, 1917 p. 210). The liability of Eastern Express’s insurance company on each of the individuals in this situation will depend on the interest that the train insured. Invariably, there are two or more parties who are always involved in an accident that occurs by a public means of transport. In this case, it is the train at fault. The insurance undertakes to pay compensation to the parties aggrieved by the accident on behalf of the driver or the company that insured the train. The insurance that such means of transport usually take among other things, provides insurance cover in respect of loss or damage that is suffered through damage of property or the death of the injury to any person resulting from an intentional or negligent act or omission by the operator or agents or servants of the o perator of the train in connection with the provisions of public passengers and transport services. Fred Fred has become permanently blind and his camera equipment, which he was transporting with him, was destroyed. While it is true that the eye sight of a film maker is essential to his job, this cannot be used as a basis to claim, future or anticipated loss of income. Fred had not yet made a deal with the television company, and it would therefore be had to calculate how much his income would have been. However, the insurance company will have to compensate him for the injuries that he has from the accident and the damage on his equipment. Albert Albert was 85 years old and suffering from terminal cancer. Even though Albert was already old and terminally ill, it would be evident that it was the accident that caused his death. However, given his age and his disease, the compensation would not be as much as for an individual who is still considered productive. His estate can only cla im compensation for the death that was caused by the accident. His age and state of health does not rule out the possibility and right to be compensated. Lydia Physically, she was unhurt but suffered Post Traumatic Stress Disorder, which stopped her working for a year, after which time she was only able to work part-time shop-assistant. However, Lydia has not been able to work as a result of her condition and would therefore require that her loss of income should be taken into consideration. If she settled her claim before the effects of her condition, she would not be in a position to renegotiate. Her circumstances are very unique and as such there would be several things to be considered, including her ability to continue with the job that she was doing before the accident. She also has a right to claim for emotional stress and the depression that her condition has impacted on her life. Cynthia Cynthia, a doctor in the next carriage, was also killed. She is at the prime of her age and has a good job. If it is proved that she is the breadwinner of her family, it would be paramount to compensate her estate relative the loss that the family has suffered. Moreover, she has a dependant, a daughter who is 15 years old whose circumstances have to be taken to consideration. As to the

Self regulation and adolescent choices in friends Essay

Self regulation and adolescent choices in friends - Essay Example Hence, Self efficacy and Choice is the topic that deserves to be analyzed and substantiated for. Recent studies on self regulation have provided an insight into how students effectively respond to influences from the outside and then integrate them with their personal experiences. In the opinion of Michael Blocher, who has analyzed individual behavior, â€Å"Self- regulation has been recently studied to provide understanding for attributes of how traditional classroom students use their cognition, meta cognition and motivation to provide a successful learning experience. Locus of self- control, learning style, self regulation skills form a part of the wholesome development of the individual as a student, a researcher and as a learned scholar† (Blocher). This fact is crucial enough to provide proof to the fact that self regulation skills are essential to the formation of attitudes, behavior styles as well as response to external environment. Further, linkages between self regulatory processes and achievement are noted to be co existent factors. In a certain assessment for 3 years, among 732 children, who were identified as possessing lower grades, it was deduced that lower achieving students were not given initiation into self regulatory methods. This draws insight into the fact that early efforts to promote self efficacy in children, self regulatory skills would enhance further academic performance, promote self belief and enhance achievement, particularly in literacy. (Liew, p.515-526). Academic performance depends largely on the ability of the student to integrate scholastic knowledge with personal experience. The ability to synthesize knowledge with experience is the chief faculty of adolescents. â€Å"They posses increasingly higher levels of abstract thinking, engage in more sophisticated and elaborate information and their processing

Research Report Paper Example | Topics and Well Written Essays - 500 words

Report - Research Paper Example Breeding of genetically modified animals is counted as a procedure too (Jha 1). The use of animals has increase by 1% in 2010. This includes the 1.6 million procedures done involving the genetically modified mice. According to Judy McArthur, a chief inspector at the animals’ scientific procedures inspectorate of the Home office, excluding the genetically modified animals, the increase is less than 1%. This is because of the increase of the number of fish up to 23%, which counts for about 93 000 of the total animals. Dogs, primates, cats and horses are protected by the law, therefore, the total number of the procedures done using the animals is 19, 773, which accounts for around 0.5% of the total. The number of the dogs used in the procedures dropped by 2%, and that of cats dropped by 32%. In toxicology tests, the number of animals used dropped by 11%. Barney Reed, a senior scientist at the RSPCA described the rise of these procedures as astonishing. He pointed out that the rate of carrying out the procedure had incerased by 37% for the past one decade. Martin Walsh, the head of the Home Office’s animals scientific procedure division, provided that efforts are being made to reduce the number of animals used for research, as well as ending the use of animals as household products. The main ethical question raised in the article is why scientists breed the genetically modified animals, yet they could be endangered by such procedures. Here, according to professor Dominic Wells from the royal veterinary college, one of the reasons why the scientists produce more of the genetically modified animals is because they have refined their procedures. The scientists, therefore, produce two lines of mice that do not show any adverse phenotype until they are crossed. This enables them to generate any number that they want before they conduct any procedure. Breeding of the mice help the scientists

Race and Ethnicity Essay Example | Topics and Well Written Essays - 750 words

Race and Ethnicity - Essay Example The programs shown should have societal standards that discourage race and ethnicity. The older television had distortions, erasures, and omissions in their reflection of race and ethnicity. There were persistent patterns of racism and prejudice in the television shows. The television channel presented a viewer with prejudice view in relation to the ethnic and racial minorities. There were absolute volumes of prejudiced rhetoric, racist images, and stereotypes in the shows and episodes. This was not an isolated case, but rather, it took place in a series of episodes in the television show. For example in the Goldberg’s TV Show that is a comedy on Jewish family, show the obstacles that are faced by the minority. The television shows violated the basic responsibilities and freedoms that the society entrusted to the television channels. This showed that there can never be freedom without responsibility. The episodes failed to replicate the multicultural and multiracial environmen t of the people and customers who were viewing the programs. However, advocacy initiatives have been done to make a difference. The televisions shows have gone under transformations and changed have been witnessed. These have changed due to the perception and enlighten on the dangers and effects of racism and ethnicity. The advocacy initiative that was developed, to change this included; participating in committees of the media, groups worked with senior managements on ways of programming and hiring. This helped to identify the discrimination and bias that was reflected in the television shows and episodes. Methods of dealing with racism in the television episodes were developed. Initiatives and efforts were done to establish television shows and episodes that were not deviant of the societal standards. Things did no change much from the earlier decade television shows to the current episodes being shown. However, there were limited changes in the television shows and episodes. The television shows started to use all people of all colors in the episodes. The actors in the shows were from all races and ethnic groups. In addition, issues that were relating to racism were covered more and shown in the television episodes. The color of people that showed special features was discouraged. The episodes showed people of a particular color to depict race and ethnicity. However, despite, all these efforts, the progress has been illusory and sporadic. The current and latest television shows continue to manifest some aspects of racism and ethnicity. Despite, the supposed changes, the television shows in the episodes still do not represent all the people of color. This unequal status in the society of the racial minorities is manifested and reflected in the episodes. Their absence in the on-air roles in television shows depicts racism and ethnicity. Moreover, they are underrepresented in the television shows and episodes. This limited participation shows cultural racism, biasness, and structural barriers. The behavior is woven in the system that has norms, values, and beliefs of the culture that is dominant. The hiring practices are what are causing the invisibility of people of color. The television episodes show the people of color as just entertainers, or athletes. In addition, they are given roles that are related to crime activities. The television programs show people of color only on limited times. These

Parenting Model Metaphor Assignment Example | Topics and Well Written Essays - 1000 words

Parenting Model Metaphor - Assignment Example Parents must be strong, patient and flexible travelers who would adjust to the situation given to them. Later towards the end of the journey, the parents would see in their golden years what kind of travelers they were. There is no course or learning program for people who would be parents one day that is why it is difficult to assume the role. It is a wonderful adventure yet quite fearful since many unexpected things can happen along the way. The important thing is to be prepared that is why married couples planning to have children must be able to settle their individual differences and adjust to each other before having a child. Each parent have different family background and experiences unless they share similar cohort ( classmates, next-door neighbors, childhood sweethearts) whose lives have been fused by their growing up experiences( Chapter 12). Nevertheless, they have their own individuality that would highly influence their decisions as they have witnessed and experienced from their collective efficacy. In short, the traveler’s backpack is already filled with their individuality that would soon come out along the journey of parenting. As they pull-out from their bags their own experiences to deal with situations (i.e. my mother taught me that the best way to cure fever†¦..) their child would absorb from them such ideas and experiences too. A bag filled with bitter, resentful, and painful life experiences would make the journey hard for the parent unless he/ she use them to teach life’s lessons and give hope to their children. The traveler’s also need to bring with them food on the journey to nourish their children with. These food are the family rituals, celebration, traditions and routine which according to Friesen helps † families establish habits that can help them succeed and connect on a regular basis. The familiarity of repeated activities and

Effective Leadership in an Organisation. Image Management, Resource Essay

Effective Leadership in an Organisation. Image Management, Resource Deployment And Relationship Development - Essay Example To effectively analyse leadership, it would be critical to decipher its meaning. There has been no standard definition of leadership with Northouse observing that â€Å"there are almost as many different definitions of leadership as there are people who have tried to define it† (2004, p.2). The author perceives leadership from a social influence perspective referring to it as a process through which one influences a group of persons, referred to as followers, so as to attain common goals. Keller (2008) defines it as a critical dynamic force which motivates and coordinates an organisation towards accomplishing its objectives. The scholar views it as less of a science but as more of an art which influences by persuasion or example to induce a desired action. Whereas in an organisational setting the term subordinates would be used in place of followers, the term followers indicates that a leader could hold any position or role with bureaucracy not necessarily being implied (Zacca ro & Klimoski 2007). Organisational leadership in particular refers to the management’s ability to acquire and protect the organisation’s benefits by being sensitive to the needs of employees and the targets of the company, bringing them together in a better environment so as to realise common goals (Abbas & Asghar 2010; Sosik, Kahai & Piovoso 2009). Nonetheless, leadership should not be used interchangeably with management. Adopting Kotter’s approach, Packard (2009) and Shapiro and Leigh (2007) noted that management would produce order, consistency and predictability with regard to key results including budgeting, planning, staffing, organizing, problem solving and controlling. On the other hand, leadership would yield change and would encompass establishment of direction through development of a vision, aligning people to the vision and strategies and inspiring and motivating the staff. Leadership encompasses visioning, management of change, development of str ategy, organisation design, management of culture and community collaboration as contrasted to management which includes financial management, program design, human resource management, information systems, project management and program evaluation (Boal & Schulz 2007; Empson 2007; Gill 2006; LePine, Piccolo, Jackson, Mathieu & Saul 2008). For management functions to be executed effectively, leadership would be a key ingredient. Effective leadership According to Keller (2008) and Pearce, Locke and Conger (2007), effective leadership would entail the development of clear objectives, strategies and beliefs and identification of crucial processes and encouraging participation of employees. But various scholars (Avolio, Walumbwa & Weber 2009; DiLiello & Houghton 2006; Yukl 2006) have argued against a particular leadership style considered as effective. Even so, various building blocks to the realisation of effective leadership have been widely accepted. Image management Avolio, Walumbwa and Weber (2009) and Chong and Wolf (2010) appreciate image management for establishment of credibility, borrowing from leadership as a social influence process described by Packard (2009). For leadership to cause any influence, the followers should accept the leader’s persuasion and appropriately respond to it. Followers would be the ones to make the decision as to whether one deserves the leadership status through comparison of the image or characteristics presented by the leader against their assumption of what constitutes a leader. This postulation has been supported by Gregersen

Games at twilight Essay Example for Free

Games at twilight Essay Both stories had an unexpected ending; in Games at Twilight this had a very sad, disappointing ending for Ravi, due to the fact that he expected to emerge victoriously from the shed after his ordeal, to find that he had not been missed. In Pineapple Cake, a certain twist in the story formed which was unexpected. Throughout the story the writer appeared to focus on Mrs Fernandez watching Victors behaviour in anticipation that he would show her up. I really expected Victor to do something that would have discredited his mother, but when the old man died it gave a twist to the events. I feel that the plot in Games at twilight, builds up an image of Ravi in his dilemma, by describing how he imagined many creatures were watching him, and how he felt about the other children, especially Raghu as he was much more dominating in character. This gave an insight to his feelings and thoughts, which build up his character. In Pineapple Cake, there is a lot of drama towards the end of the story when all the attention focuses from Victor to the old man who has died in the middle of the wedding ceremony. I feel that both these stories have different plots that lead onto the main events. Both stories give an insight into the minds of the children through their actions and observations. Each story is written about children, which includes their thoughts and feelings around the situation theyre faced with. In Games at Twilight, very little is given by direct comment about Ravi, only that he is small. Whilst he is in the shed the writer expressed how he felt by his reactions to the dark, spooky shed. He was frightened of this situation especially the creatures that may be watching him. In Pineapple Cake, Victor was described as being Nervous rather than rebellious child, this was perhaps true because of his bombastic mother who appeared to control him by bribery. Apart from his child like tendencies, I do feel that he was sensible as he demonstrated good behaviour in his mothers presence even thou he knew he may not get is reward. Both stories do have a sad ending. In Games at Twilight, Ravi wanted to make an impression on the other children, especially Raghu. These were destroyed when he came out of the shed and realised his insignificance amongst the other children. In Pineapple Cake, it also ended in a sad event. Victor endured a day in uncomfortable shoes and clothes and in a boring environment. At the end the death of the old man affected him so much that he was no longer interested in his promised pineapple cake. It appeared that Victors father was not present at this event. There is not much reference within the text describing his father, only Had his father brought him here on a Sunday outing, he could perhaps be working or not living with Victor and his mother. She dominated and insulted victor, saying Dont you go and wet your pants, man, This may have caused him to be withdrawn and quiet, but I do think that he is smart because throughout the story his mother promised him this cake and he knew she wasnt very reliable in keeping a promise. Games at Twilight gives little mention of the mother and appears to be centred on the children and their activities, Which is play. This is centred on their mischievous and noisy games and gives Ravi personal experiences and disbeliefs in the other children. In Pineapple Cake, the story is focused on a child and his mother, who are attending this posh wedding. In the whole story she comes across in a boisterous manner towards Victor. She believes she is important and was looking forward to Having tea at Greens, you know. From her attitude and feelings towards Victor, you are able to form a character of a women who was impatient, Well, come along, get dressed quickly yes, yes, and insensitive through the way she had Victors cake after the death and said I think wed better go now. Both stories express the frustrations of each child within the story. The writer does this by showing their inability to control each dilemma theyre faced with. I did enjoy Pineapple Cake, rather than Games at Twilight, as the plot had more humour to it and there was plenty of action. I could also feel an element of suffering for Victor during his stressful day. The end of the story came as a complete surprise to the reader.

Is located in Wellington. The office has total 52 PCs which are allocated between three major departments: Sales, Accounting and Marketing. Each departments computers are connected via cables to Switches, which in turn are connected to the central Switch for further connection. Central Switch is also connected to 8 Servers that provide all necessary services for the network. However the main connection to the internet is provided via DMZ connection network in face of four servers (DHCP, File, Web, Email) which are also connected to the hub. The hub in turn is connected Router which also acts as Firewall in the internet connection. Napier and Christchurch have similar networks, as both are connected to internet via ADSL technology. And both are connected to main office via router-to-router VPN connection. In order to create ADSL supported network, it is required to have DSL Modem, which can be connected to internet via landline cord. In turn, Modem is connected to Router in order to delegate internet to the users via Switch, which is connected to the PCs. In addition to that, one of Napier PCs are configured to establish VPN connection. Auckland branch. This network has 18 PCs in three floors. 12 PCs are connected to the network via Switch directly by cables. Meanwhile, third floors 6 PCs are connected to Switch via intermediary Wireless Router with help of WMP300N module. Switch in its turn allows to connect to the public networks (Internet). This may be arguable to have two routers instead of one, but I believe that additional Wireless Router will provide more stable and constructive connection. Tauranga. The network, has been established with DMZ connection starting with properly configured Firewall/Router in order to work with several IP addresses. Router is connected to Hub. Hub is connected to Servers which are used for proper services performances, which in turn are connected to the Switch, that connects PCs to the network. Task 1/E. All of the branches are set to be connected to the main office with the use of VPN. All VPN connections from branches to the main office are connected to the Firewall. Firewall in turn, is configured with all the restrictions and access policies. As is written in scenario, the branch can connect to the main office via on-demand router-to-router VPN connections. On the other hand, as given example with Auckland branch, it can connect to main office, by persistent VPN connections that stay connected 24/7. Task1/F. In case of the Partners, they can connect to the main office network via VPN connection. But in common cases they use Cisco VPN utility that contain SSL certificate, IP address, password. Meanwhile Firewall is configured with identification of these IP addresses, based on which certain access level is delegated for the partners. Task 2/A. In case of main office, DHCP, File, Web and Email servers have static IP addresses which route 10.51.0.0 network and 192.168.14.0. In Napier branch Router2 has default routing. As well as Christchurch branch. In Auckland branch, we face the same case of both Routers to have default routing. Finally, in case of Tauranga, Web and File servers, also have static IP addresses which route 10.51.0.0 network and 192.168.10.0. Task 2/B. For t Static routing tables were used to configure the networks. In addition to that, default routing was implemented in all routers. To ensure correct work, tracert command was used in command prompt. Bibliography Requirements for IPv4 Routers, F. Baker, RFC 1812, June 1995 Ingress Filtering for Multihomed Networks,RFC 3704, F.

The Cuban Missile Crisis: Eyeball to Eyeball :: American America History

The Cuban Missile Crisis: Eyeball to Eyeball Eyeball to Eyeball: America, Cuba and The Soviet Union America and The Soviets again using other countries for their own warfare Excitement was high for Cuba, when Fidel Castro overthrew the dictatorship of Fulgencio Batista in January 1959. With a heady mixture of nationalism and left - wing ideologies US became very cautious for its southern comrades Central and Southern America and perhaps herself. When Castro took over Cuba, the US lost valuable investments in the sugar and tobacco crops of Cuba. Fearing the spread of communism into Americas' backyard the US Government imposed a strict economic blockade hoping to starve Castro into US policies. In desperation Castro turned to the soviets for balance of powers to weigh up the balance of communism ideologies. In February 1960, Castro signed a trade pact with the Soviets, which eventually led to close diplomatic relations. At this time the US Government became more worried that a communist superpower had ventured so close to her borders. By authority of Eisenhower, Cuban Exiles that were in the US at the time were given aid. At the same time the CIA began to train selected groups of the exiles to re - enter their homeland and over - throw Castro's Government. When Kennedy was sworn into parliament in 1961 he took over the proceedings with hesitation for his states security. He advised a plan to invade Cuba once again after Eisenhower's two other invasions failed. This invasion was known well as the Bay of Pigs. In April Kennedy received reports that the invasion failed which boosted Castro's prestige and embarrassed Kennedy of his new presidency. When the Bay of Bigs disastrously ended it built up confidence for the soviets and Castro and lowered Kennedy into a worriment of what's to happen next. Early 1962 Khrushchev was convinced of Kennedy's weakness after the capture of Gary Powers and that they had ceased to carry out U-2 reconnaissance missions over the Soviet Union for the capture. A while after the Vienna Summit the Soviets formed yet another policy with Cuba of 'Brinkmanship' seeing how far the Americans could be pushed before reacting. Although this strategy was a dangerous one the Soviets were thinking of the opportunities that could arise from this. One was the advantage of an east - West balance that the Soviets could start to infiltrate the Americas with their ideologies.

A Modest Proposal Concerning the Environment Essay -- Environment Envi

A Modest Proposal Concerning the Environment * Based on Jonathan Swift’s â€Å"A Modest Proposal† (1729). It is a melancholy object to those who travel through this great country to see isolated corners of this fair realm still devoted to protecting the environment. The wretched advocators of these ideals are frequently seen doling out petitions and begging at their neighbours’ doors to feed their obsession, which keeps them in the contemptible poverty that they so richly deserve. I think it is agreed by all parties that it is an eyesore to see these people blockading the roads to prime tree-cutting land and bombarding our most respectable government with impractical proposals. It is not so Herculean a task to discourage these self-named â€Å"environmentalists† in their follies by paying them no heed. However, a new generation of them has sprung up. Citing how it is in fact profitable to protect the environment, they try to pull blindfolds over the public’s eyes. Therefore, whoever could find an easy and economically sound method of reclaiming these lost souls would deserve to be made the head of our nation at the very least. But my intention is very far from being confined to converting the people who are currently obsessed with protecting the environment; my aims are much more marvellous, and shall take in the whole number of people capable of falling in love with nature. Now, sustainable development and quality of life are crucial to the well being of our nation. Thus, I have pondered many a year on this very important matter and have consulted a very knowing Canadian of my acquaintance at the World Wildlife Fund (WWF). The amount of natural resources in this country being usually reckoned infi... ...rs with them. This will lead to the unity of a strong nation. Fifthly, we can achieve our ideals of obtaining sustainable development and a high quality of life; we will also be able to save the lost â€Å"environmentalist† souls from wandering past these ideals. There are many other advantages to my humble proposal, such as having fewer issues to worry about and having the knowledge that we humans can harness Nature. As you all know, knowledge is power. I can no more think of any objections that might be raised against this proposal, but I can assure you that I stand to gain nothing from these necessary suggestions, as I own neither lakes nor rivers, and I do not have any stocks in the biotechnological market. I have no other motive than to bring about the public good of my country, by advancing our trade in the exploitation of nature.

Fossil Fuel Consumption, Co2 And Its Impact On Global Climate Essays

Fossil Fuel Consumption, CO2 and Its Impact on Global Climate Background: At the beginning of human history, we had to satisfy our energy needs (for food, heat and movement) by using our own muscle power and gathering or hunting naturally available plants, animals and wood. Each stage in the evolution of human society (the development of farming, domestication of animals, harnessing of wind and water power) increased the average per capita energy use, but it was the Industrial Revolution and the exploitation of fossil fuels which marked the transformation of societies into the energy-intensive economies of today. Since the eighteenth century the industrialising countries have come to rely on non-renewable energy resources, and at present about 80 per cent (Myers, 1994) of the world's commercial energy is derived from oil, coal and gas. Although it has been observed that the growth of energy consumption is closely correlated with the increases in gross national product thus our economic development, the major sources of energy (that is fossil fuels) are 'stock resources'. Fossil fuels are consumed by use and the current consumption patterns are non-sustainable. It is recognised that energy conservation and the development of renewable energy sources will be needed to sustain economic growth. The quantity of ultimately recoverable fossil fuels is limited by geology and remains a matter of suspicion, but the view of the 1970s that scarcity was imminent is still popular. It is the 1973 Oil Crisis marked the transition from abundant, low-cost energy to an era of increasing prices and scarcity. Today concerns over scarcity have been overtaken by the question of whether human beings can afford to meet the environmental costs of continued fossil fuel consumption. One of the most widespread concern related to global climatic changes. Introduction: Climate represents normal weather condition of an area over a period of many years. This is in contrast to weather which is the day to day changes in the atmosphere. It is now realised that our global "climatic normals" had fluctuated in the past millions of years which was nowhere related to human activities. Nevertheless, with the increasing human population and our reliance on fossil fuels since the last century, we have definitely 'participated' in the climatic changes which are taking place to a certain e... ...creasing over the last decade. More on that, it is a fact that the burning of fossil fuels do release infrared-absorbing carbon dioxide to our atmosphere. Therefore, it is just a logical conclusion that the greenhouse is here, as it always does. It appears that there is excessive heating within the greenhouse which is induced by our increasing rate of fossil fuel consumption, and the problems that lies behind global climatic change are far reaching . Perhaps, the real limit to our fossil fuel consumption will be the CO2 problem but not the size of the resource. A Chinese proverb says that "prevention is better than cure." Approaches to energy conservation could be the key. Bibliography: Benarde, M. A., 1992, Global Warning†¦ Global Warming, John Wiley & Sons, Inc., 52-65.

Billy Budd †Foreshadowing Essay

Foreshadowing – in which a certain image or event may hint at something that becomes more significant later on in the story. Authors often use different literary devices to grab the reader’s attention, or to establish basis for plot development later on in the novel. In Herman Melville’s Billy Budd, Melville uses the literary device of foreshadowing to allow the audience to be aware of Billy’s inevitable fate before the characters in the novel, thus creating a feeling of suspense within the novel. In chapter one, the incident with the Red Whiskers (12) functions as a foreshadowing of Billy’s confrontation with Claggart. This is very similar to what happens later between John Claggart and Billy (58). Melville uses the incident to show that although Billy Budd is a gentle man, unwilling to quarrel, he can become aggressive if provoked. This makes the later incident more believable, since the reader has already seen Billy behaving in this way. The Red Whiskers is similar to Claggart in a number of significant ways. Like Claggart, the Red Whiskers dislikes Billy, and out of sheer envy he â€Å"bestirs† himself to pick a fight with Billy. Melville begins using foreshadowing early in the novel when he describes Billy Budd as a tall handsome sailor that was well adored by mostly all who knew him. Melville makes Billy seems flawless until he informs the audience using straight, matter of fact sentences that Billy has a speech impediment that only seems to rear its ugly head whenever Billy has something of importance to say (17). The fact that Billy’s speech impediment only shows when he has something significant to say helps inform the audience that something of significant importance will happen later on in the novel (57). Billy’s inability to speak during times of emotion will mean that later, he cannot speak the truth and save himself. Vere’s nickname is ironic in a second way, although the narrator does not point this irony out explicitly. The character referred to as â€Å"Starry Vere† in the Marvell poem is a severe disciplinarian (24), whereas Captain Vere is anything but harsh or brutal in his conduct. But while the name seems ironic  at this point in the story, the passage quoted from the poem provides an important piece of foreshadowing. Vere does indeed impose an unexpectedly harsh discipline upon Billy, and his commitment to principle is what prompts him to be severe (60). Without the element of foreshadowing within Billy Budd it seems almost incoherent that the events of the novel would have come together. Melville’s use of foreshadowing allows him to take the audience on an unforgettable journey through the life and troubles of Billy Budd and allows the audience to get a full understanding of the situations leading up to Billy’s tragic end.

Engineering Education in Ghana

2.2.4 EducationEducation serves as an engine for economic growing through the accretion of human capital. Education is strongly associated with boosting degrees of societal capital ( Campbell, 2006 ) . the act or procedure of leaving or geting general cognition, developing the powers of concluding and judgement, and by and large of fixing oneself or others intellectually for mature life ( Dictionary.com, 2014 ) .2.2.5 ENGINEERING EducationEngineering instruction is the activity of learning cognition and rules related to the professional pattern of technology. It includes the initial instruction for going an applied scientist and any advanced instruction and specialisations that follow. Engineering instruction is typically accompanied by extra scrutinies and supervised preparation as the demands for a professional technology licence.2.3 Technology Education IN GHANA OVER THE YEARSEngineering instruction in the so Gold Coast dates back to the 1930’s. In August 1931, the Colonial Government requested Achimota College in Accra to form an technology class to develop Africans for senior assignments in the Public Works Department, the railroads and subsequently, the mines. The class, which was based on the external grade course of study of the University of London, consisted of four and a half old ages of survey at Achimota, followed by between three and four old ages of structured post-graduation practical preparation. Initially, the class offered at Achimota led to grades in electrical, mechanical and civil technology, but with the enlargement of activities in the excavation sector in the Gold Coast, it became necessary for the School to spread out its class offerings to include excavation technology. In malice of the troubles it experienced, the Achimota Engineering School managed to turn out a sum of 25 applied scientists before the start of the Second World War compelled it to close down. These applied scientists were to play cardinal functions in the imme diate post-independence development of Ghana and besides served in other African states every bit good as working for international bureaus. With the constitution of the University College of the Gold Coast in Legon, Accra in 1948, university instruction was phased out of the Achimota College campus. Unfortunately, no proviso was made for the transportation of the technology classs to the new University College, therefore the preparation of applied scientists was interrupted between 1948 and 1952 when a School of Engineering was once more established as portion of the new Kumasi College of Technology and the equipment, and some staff of the Achimota Engineering School transferred to Kumasi to organize the karyon of the new school. From 1952 to 1955, the School of Engineering prepared its pupils for rank of the assorted Professional Institutions in the United Kingdom. The formal preparation of alumnus applied scientists of assorted specialisations commenced in 1955 in particular rela tionship with the University of London and pupils were prepared to take Partss I, II and III of the University of London Bachelor of Science ( Engineering ) External grade scrutinies. The first professional applied scientists produced by the Kumasi School of Engineering, who were all civil applied scientists, graduated with the university of London External B.Sc. ( Eng. ) grade in June 1959. The School of Engineering began to present its ain technology grades in June 1964.2.3.1 Technology Education FOR NATIONAL DEVELOPMENTRelevance of technology plans to the demands of industry has sometimes been interpreted as a state of affairs in which the merchandises of an technology plan are to be trained to be of immediate usage to industry after small or no post-graduation preparation. Pressures, hence, be given to be put on African technology modules to cut down on the content of the theoretical facets of their classs in favour of vocational facets – force per unit areas which are, i n bend, frequently ferociously resisted by technology pedagogues. Yet, technology plans in African Universities stand to derive enormously when there is active co-operation between technology pedagogues and the chief consumers of technology work force based on common regard and clear grasp of the functions of the assorted stakeholders. It is besides anticipated that the technological spread between the developed and the underdeveloped universe will go even wider in the twenty-first Century, therefore, doing technology preparation even more situation-specific. This will intend that Ghana will hold to depend even more on her national establishments for the preparation of the technology work force relevant to their development demands. It will, hence, be necessary for the professional associations and the preparation establishments in Africa to co-operate even more closely in specifying the content of the technology course of study of the twenty-first Century.2.4 DESIGNING AN ENGINEERI NG SCHOOL2.4.1CONDUSIVE TEACHING EnvironmentTo forestall the assorted jobs pupils and lectors face in the schoolroom, it is of import to set into consideration the agreement of the schoolroom. Savage 2009 indicates that, the physical agreement of schoolrooms plays a prima function in the character defining of pupils and goes a long manner in bettering the academic public presentation of pupils. If a schoolroom is non good designed, it affects the end product of pupils, hence hindering on the intent for which talks are intended. The research on schoolroom environments suggests that schoolrooms should be organized to suit a assortment of activities throughout the twenty-four hours and to run into the teacher’s instructional ends ( Savage, 1999 ; Weinstein, 1992 ) . The criterions for finding what spacial lay-out is most appropriate to carry through these maps include: ways to maximise the teacher’s ability to see and be seen by all his or her pupils ; ease easiness of mo tion throughout the schoolroom ; minimize distractions so that pupils are best able to actively prosecute in faculty members ; supply each pupil and the instructor with his or her ain personal infinite ; and guaranting that each pupil can see presentations and stuffs posted in the schoolroom. Seating agreement in talk halls are really important since it indicates whether there will be societal exchanges in the category is task behaviorally delighting. It is besides really important to forestall high traffic countries in schoolroom designs, such as waste basket countries. Critically, it is really of import that, pupils have a clear position of the lector at every point in clip ( Quin et al. , 2000 ) . In making so, the lector should besides be giving freedom in his motion through the talk room or schoolroom. There is some grounds that it is utile to restrict ocular and audile stimulation that may deflect pupils with attending and behaviour jobs ( Bettenhausen, 1998 ; Cummings, Quinn et al. , 2000 ) . The physical agreement of the schoolroom can function as a powerful setting event for supplying pupils effectual direction and facilitate ( or inhibit ) positive instruction or learning interactions. As with other facets of direction, the physical agreement of the schoolroom should be brooding of the diverse cultural and lingual features of the pupils and be consistent with specific scholar demands.2.4.2 STAIRWAYSStairwaies are seen as connections between at least two different degrees. Vertical risers and horizontal paces are connected to stairss over a incline. It can besides be defined as a system of stairss by which people and objects may go through from one degree of a edifice to another. One of the most critical parts of school traffic design is the staircase, which should be located in relation to the inclusive traffic form, maintaining in head burden distribution, safety, finish of pupils between periods and riddance of cross traffic. The staircases should be designed for unsophisticated, fast, and safe motion of male childs and misss. Stairways non merely supply entree to and from assorted floor degrees, but they are used at every period for the perpendicular circulation of pupils altering categories. It is of import that staircases should be designed to guarantee that male childs and misss with books under their weaponries may walk side by side to avoid congestion ; a breadth of 4 pess 8 inches to 5 pess between bannisters is recommended. Stairwaies should be of fireproof building, taking straight to the out-of-doorss. They should be equipped with smoke-control installations, dividing the stairwells from the corridors which they serve.2.4.3 CorridorA well-designed school has corridors that accommodate the free and informal motion of pupils. The narrow corridor normally requires formal, regimented, and supervised traffic flow. The walls of corridors should be free of all projections. Heat units, imbibing fountains, fire asphyxiators, cabinets, doors, and show instances should be recessed in the involvement of pupil safety. Acoustic belongingss are desirable to cut down hall noise. Corridors should be good lighted, with exigency proviso in the event of chief power failure. Floor covering should be lasting, nonskid, and easy to keep. The maximal length of unbroken corridors should non transcend 150 pess to 200 pess longer subdivisions give an unwanted position.2.5 FORMAL SPACES2.5.1 CLASSROOMSClassrooms have comparatively straightforward demands: line of sight, good acoustics, and a focal point at the forepart of the room helping as the platform for instructors to talk. Physical restraints such as the ability of pupils to turn around in their seats, can restrict the success of a designed schoolroom infinite. The room may be designed for pupil coaction. Seatings may be arranged in mated rows with specially design chairs that allow pupils to confront each other for coaction. Apart from the schoolroom and formal infinites, educational establishments are besides designed with the proviso of informal infinites in head.2.5.2 OfficesThe finding of whether an office or cell will be assigned is based on an person ‘s occupation description and place within the organisation. Factors such as confidentiality or security demands, figure of employees supervised and particular equipment demands will be evaluated. Offices should be placed near the inside nucleus infinite. This increases the incursion of natural visible radiation into the edifice. When it is impractical to turn up offices near the inside nucleus, door running lights and borrowed visible radiations should be considered to convey daytime into the interior infinites. Translucent glazing such as frosted or patterned glass can be used if there is a ocular privateness demand. Offices located in the inside of the edifice infinite should be provided with a door or running light assembly or a borrowed visi ble radiation ( interior window ) in at least one wall at a tallness above the finished floor that allows ocular privateness while conveying visible radiation from the exterior.2.6 REQUIREMENTS OF LECTURE HALL SPACES( The followers demands of a schoolroom design have been taken from the â€Å"University of Maryland, Baltimore County General Lecture Hall Design Guidelines, and Revised August 25, 2000 ) . Physical Access and Movement – The design shall take into history the flow of pupils both in and out of the infinite and within the infinite every bit good as the demand for the teacher to travel about in the forepart of the room. 1. Sufficient infinite is needed near the forepart of the room for puting up audiovisual equipment, such as projection screens and charts. 2. Ceilings should be a upper limit of 9.5 pess high. 3. Light from Windowss should, if possible, come over a student ‘s left shoulder. No lector should be required to confront the Windowss when turn toing the category from the normal teaching place. 4. Ceilings and/or walls should be acoustically treated. 5. Floors should hold a cushioning stuff. 6. The schoolroom should hold as quiet a location as possible, off from noisy out-of-door countries. Ease of entree to specialise installations outside the academic unit should be ensured.2.6.1 DOORSThe flow of pupils should be the major factor in finding the location of entrywaies. Entrances should be located to avoid pupil traffic go throughing through non-instructional countries. In add-on, big Numberss of pupils going in corridors and hallways can bring forth unwanted noise. In finding the size of entrywaies and issues, constructing codifications should non be the lone standard. The flow of pupils in and out of suites can hold a major impact on size of entrywaies and issues. The design of entrywaies, issues, stepss, corridors, and exterior waies should take into history between-class pupil traffic. For illustration, it is non realistic to presume that a room will be wholly vacant when pupils begin geting for the following category. Provision should hence be made for vision panels in entryway doors. They could be tinted. Besides, proviso should be made for door Michigans to protect the wall surface.2.6.2 FLOOR, WALLS AND CEILINGSIn smaller schoolrooms, it is common to utilize vinyl composing tile or rug. Rug should be provided in all suites unless subject particular related classs dictate otherwise. The ceiling tallness is another of import consideration when planing the infinite. For illustration, because a projection screen must be big plenty to expose images of equal size, it must be placed high plenty from the floor to supply unobstructed sight lines. This normally requires a ceiling tallness higher than the standard eight pess.2.6.3 NOISE CONTROLOther of import factors must be considered in the design. To avoid the noise generated by their operation and usage, peddling machines must be located as far off as possible. Trash and recycling containers should be located near the peddling machines. Restrooms and imbibing fountains should be located nearby and should be designed to manage pupil usage between categories. To forestall unwanted noise transmittal, public toilets should non portion common walls, floors, or ceilings with instructional infinites

Amyotrophic Lateral Sclerosis Essay

Many people are affected by genetic disorders every day. Abnormalities in one’s DNA are what cause a genetic disorder. These disorders could be as little as a mutation in a single gene. In another case, they could be as severe as having an extra chromosome, or taking away a chromosome. Genetic disorders are present from birth, but they may not be visibly seen until a later age. Some mutations could be heritable, or from your parents genes. Some forms of cancer can be inherited form a parent. Although, in most cases, these mutations are new changes to the DNA. â€Å"All humans have the same basic set of genes†. This means that everyone has the probability that they could get a genetic disorder. The thing that makes us different is the genetic sequence. There are many different types of genetic disorders. A few of them are: Angleman syndrome, Hemophilia, Sickle-cell disease, Neurofibromatosis, Cri du chat, and Down syndrome. People are born with these diseases and have to face many challenges every day to live with these genetic mutations. This essay is going to specifically cover one genetic disorder called Amyotrophic lateral sclerosis. Amyotrophic lateral sclerosis, also known as Lou Gehrig’s disease, is a genetic disorder that occurs in the nervous system. Each word in ALS briefly describes what the disorder is. Amyotrophic has two parts to it. The prefix â€Å"amyo† means muscular atrophy. Atrophy means to waste away, typically due to the degeneration of cells. The suffix â€Å"trophic† means that it is relating to feeding and nutrition. So to sum it up, amyotrophic means that the muscles have lost their nourishment. Lateral usually means the side of something. In this case, it means that the mutation is affecting the sides of the spine. The sides of the spine are where the nerves that nourish the muscles can be found. Sclerosis is the abnormal hardening of body tissue. In this case its referring to how the mutated part of the spinal cord develops hardened or scarred tissue, in place of healthy nerves. The mutation damages nerve cells in the brain and the spinal cord. The damage caused by it, most of the time, leads to one’s death. After motor neurons die, the brain is unable to control muscle movement, and the victim becomes paralyzed. It targets the motor neurons that allow you to make voluntary movements and it effects your muscle strength. Voluntary movements are movements in which you control. These are movements that require you to think about the action in order for it to happen. For example, lifting you leg to kick a ball is a voluntary action. Involuntary actions do not require any thinking and some happen automatically, such as your heart beating, or breathing. There are many symptoms in that come along with ALS. Most of the symptoms do not occur unless people reach the age of 50. Although there have been some cases, where the symptoms occur in younger people. According to some studies, the first two muscles that are most often affected are the muscles that allow you to swallow and breathe. There can be many noticeable symptoms because your muscles get weaker. You may notice an increase in gagging, drooling, and choking. You may feel that you cannot lift your head up, because your neck muscles are weak. There are many physical tests that can be given to attempt to diagnose Amyotrophic lateral sclerosis. Certain physical tests could show muscle weakness in certain areas, weird walk or posture, and abnormal reflexes. There are tests that can be used to diagnose ALS. One method is taking a blood test, so that the doctors can rule out any other possible disease that it could be. Victims can also receive a spinal tap, a MRI, or even a family background check to see if there is any history of ALS in the family. There is one major problem with Amyotrophic lateral sclerosis. Scientists and doctors have still not been able to find a permanent treatment for it. Although there is one medicine called riluzole that can slow down the symptoms, giving victims longer to live. Physical therapy and the use of braces, are non-medicinal ways of helping with the muscle weakness. There are many medications that can be used to help with specific symptoms of ALS. Since choking is common in someone with ALS, most people are hooked up to a tube and are fed through it. This is called a gastrostomy. A gastrostomy is when they make an opening in the stomach from the abdominal wall so they can put in food. This is obviously a surgical procedure. Amyotrophic lateral sclerosis is named after Lou Gehrig, who was a famous baseball player in 1930s. The French refer to it as Maladie de Charcot because the first recording of ALS was in 1869 by a French doctor named Jean-Martin Charcot. Stephen Hawking is one of the more famous people with ALS. He has had ALS since the start of his adult life, and he has been living with it for more than 50 years. Most people die from it three to five years after the symptoms become noticeable. This is why Stephen Hawking’s case is very special. It was just after his 21 birthday when he found out something was wrong. Yet he is still living and doing the most he can with his life. For example, being one of the smartest people on earth. People that live with ALS every day. Once the symptoms start to show, and or get serious, they are unable to care for themselves. They are usually taken care of by a family member or even a close friend. In some serious cases, victims must remain at the hospital because they are unable to eat and function without medical assistance. As mentioned previously, the victims sometimes have to be fed through a tube because they are unable to chew. Living with ALS is a very hard thing to do.

Homophobia in Schools

Homophobia is a problem in many public and private school systems, denying homosexual students a safe learning environment. Everyday a student is discriminated against because of his sexual orientation. Gay, lesbian and bisexual students are being verbally, physically, and academically abused. Homophobia is taking hard working students and creating a negative and damaging learning environment for them. It’s time for a change. Words like â€Å"faggot, queer, homo, fairy and dyke† have become common â€Å"insults† in today’s school systems.These words are unacceptable, yet time and time again I observe teachers doing nothing when they hear said words being used. If however I were to use a racial slur such as â€Å"nigger† I would be immediately reprimanded and possibly disciplined. Discriminating against someone because of who they love is inexcusable. Schools NEED to do something to combat this growing problem, Girard may have an anti-bullying progra m instituted but what does it really do to combat it? Nothing. They preach equality, but do they enforce it?No. Instead of instituting programs to teach equality, punishments must be given out. Instead of being passive, schools should be aggressive in defending the victims of all forms of bullying. Students who identify themselves as â€Å"gay† are up to five times more likely to miss school due to feeling unsafe, 28% of them are forced to drop out. And yet school administrations do nothing about it. In fact 85% of teachers actually oppose integrating lesbian, gay and bisexual themes in their curricula.Frighteningly A 2007 survey found that four out of five young lesbian and gay people have no access to any information about LGBT issues at school. There are many different ways in which LGBT people experience homophobia, including malicious gossip, name-calling, intimidating looks, internet bullying, vandalism and theft of property, discrimination at work, isolation and reject ion, sexual assault, or even being sentenced to death. All forms of homophobia are destructive, not just for people living openly as LGBT, but for society as a whole.Living in a homophobic environment forces many LGBT people to conceal their sexuality, for fear of the negative reactions and consequences of coming out. For people who have been brought up to believe that homosexuality is wrong, the realization that they might be gay can cause feelings of shame and self-loathing, leading to low self-esteem. Suppressing homosexuality involves denying an important part of a person's identity, and can have a serious impact upon their life and relationships. Furthermore, the dilemma of whether to ‘come out’ or not can cause a great deal of personal distress.

Business Ethics Essay Example | Topics and Well Written Essays - 750 words - 6

Business Ethics - Essay Example One of the ethical issues that emerge occasionally in a business environment is treatment of lost and found properties. This essay seeks to evaluate a case study in which a student finds a lost iPod and is faced with the decision of whether to keep it or not. The essence of this essay is to identify the contentious issues that must be observed while settling a personal dispute. The issue of keeping a lost and found property has garnered a lot of ethical analysis with the controversy arising of whether such a person should be equated with a thief. However, business ethics are grounded on the ability of a person to assess whether an action is good or bad depending on the results of the action. Any action that has a negative effect to another person or to the business is considered wrong and punishable. In such a scenario, the student who found the iPod, their friend and the judicial member all have must use critical decision making approach to arrive to the right course of action. The student who found the iPod has a choice to either keep the gadget it to the legal body of the school. Their friends have a role to advise the student on the ethical course of action to take when they are consulted. The best strategy to make a worthwhile decision is to weigh the effects results of keeping the gadget. In corporate ethics, the best course of action is one that does not hurt any individual in the organizational environment (Hartman, 2008). Handling of lost property in an organization is an ethical issue that can attract a legal action or even punishment. In an organization, if a person finds a lost item, they have a role to find the owner or submit the property to the legal committee of the institution. According to organizational ethics, taking a lost property is a legal issue that is equivalent to stealing. The legal issues that arise from an act of stealing include loss of business trust, lack of transparency and criminal guilt (Hartman, 2008). On religious grounds, if one finds lost property, it is ethical to put an effort to establish the rightful owner, rather than keeping it. In this view, if the student keeps the property, they defy the moral responsibility that is expected in an organization and hence can be accused of stealing. If the student opts to keep the found items and is eventually reported for theft, the student representative in the judicial board members has a role to provide a ruling on the case. To do this, the judicial member would require getting the material facts associated with the dispute. For instance, the cost value of the object, in order to determine whether the gadget was valueless when found. Any valueless object voluntarily abandoned is regarded as trash and if a person who finds it is not guilty of theft (Hartman, 2008). If the item is found to have a value and it is proven that it was abandoned involuntarily, then the student is guilty of stealing for not submitting the iPod to the judicial body. In this scenar io, the student can only defend themselves if there is evidence that he or she submitted the lost item to the legal body and efforts to establish the owner were futile. Other stakeholders in this case would include the friend of student who kept the device as well as the rightful owner The student representative in the legal affairs has several decisions to take in settling the dispute in this case. The first option would be to return

Low density polyethylene Research Paper Example | Topics and Well Written Essays - 1250 words

Low density polyethylene - Research Paper Example In recent years, another dimension of environmental aspect has been added to reduce the global warming and related factors. (LDPE PERP 2010, p4) This paper deals with mainly the production processes of LDPE and its effect as life cycle assessment. Production Processes Installed capacities of LDPE based on production processes employed can be presented schematically as per the following diagram. Source: http://www.chemsystems.com/about/cs/news/items/PERP%200809_1_LDPE.cfm The technologies based on tubular and autoclaves reactors are used for the polymerization of ethylene. Polymerization process is carried out at high pressure between 1500 and 3000 bar and at temperature between 120 and 320 degree centigrade. A large variety of grades are produced using a single reactor line. Tubular Reaction Process The major outlines of the process can be described as per the following. Ethylene feedstock is compressed and mixed with the recycled ethylene and co monomer such as ethyl acrylate, vinyl acetate, or methacrylic acid. The mixture is then pressurized in the tubular reactor at certain pressure. Polymerization of the monomer takes place in the presence of organic peroxides. Reactor has several zones to increase the conversion rates. Per reactor pass conversion rate is found to be between 15 and 35 percent. The separation is done in two stages. The mixture of ethylene and polyethylene enters the high pressure separator and splits into an ethylene rich gas and polymer rich liquid. The polymer rich liquid at the bottom of the high pressure separator is taken out to the low pressure separator. The ethylene gas leaving the separator is sent back to the compressor and again mixed with fresh ethylene. The liquid stream is taken to the extruder for making the pellets of the polymer compound. (Pladis 2006) ExxonMobil has a long history of working with tubular reactors to manufacture LDPE. As claimed by ExxonMobil, tubular technology has a lower operating cost than autoclave tec hnology. Currently, 14 plants are in operation based on tubular technology as provided by ExxonMobil giving production output of 2500kta at different locations. (LDPE tubular†¦2010) Autoclave Process The compressed ethylene feedstock is mixed with comonomer such as ethyl acrylate, vinyl acetate, or methacrylic acid. Then the mixture is allowed to enter secondary compressor where it is compressed at very high pressure of 45,000 psi before entering autoclave reactor. Initiator accelerates the polymerization process. The molten polyethylene is taken out through separator and taken to extruder for making pellets and further processing. (Lyondellbasell 2010) A typical flow diagram of autoclave process for producing LDPE can be represented as per the following. Source: http://www.lyondellbasell.com/techlit/techlit/Tech%20Topics/Plant%20Profiles/Autoclave%20LDPE%20Technology.pdf Tubular versus Autoclave Reactor Processes Both, tubular and autoclave, are proven processes but there is s ome subtle difference in the product structure of resins produced from these processes. The difference lies in the level and type of long-chain branching. The autoclave process provides more long-chain branching compared to those provided by tubular reactor. That is due to higher level of backmixing possible in case of tubular reactor. In contrast, tubular reactor provides little backmixing as the reaction flow carries the polymer down the tube as reaction progresses; however, such subtle

Women in the French Revolution Essay Example | Topics and Well Written Essays - 1250 words

Women in the French Revolution - Essay Example The French Revolution is commonly considered in the light of governmental changes and democracy; however another important aspect of this war was the women and the way that their rights were affected. There has been significant interest in the role of women during this time, particularly women writers who attempted to promote their opinions and desires through writing. Although women played a significant role in the French Revolution of 1789, this contribution was neither acknowledged nor rewarded. Instead, the concerns of women were relegated to the sidelines, and those that attempted to express or desire their own rights were suppressed1. Although the French Revolution brought about change for the country and resulted in the creation of a constitution, and a declaration detailing the rights of men, it was until 1944 that females were legally considered to be French citizens. Consequently, while the political environment of France was focused on the social change occurred as a resul t of the revolution, females were fighting for their rights, and striving for their voices to be heard2. The changing roles of women The French Revolution spurred many ideas about the role of women and significant debate about the way that women should be treated in society. Although many of these concepts were not new, but had been debated in the previous century, the change that accompanied the French Revolution increased passion and urgency in these ideas and brought them to the forefront3. The dominant culture in France prior to the Revolution as well as after it, considered females to be important in the domestic arena, and that it was not right for them to be involved in any public sphere4. However, the 17th century was the beginning of women gaining knowledge and seeking education for themselves. Women began to engage in discussion about subjects that had previously been beyond their reach, such as politics, science, literature and philosophy5. Because of this, women were beg inning to form strong opinions of their own, and were gaining the strength to speak out against their male counterparts and against those in authority. A number of women played a significant political role during the French Revolution, despite the expectations of their society, which felt that females should be passive in terms of political expression6. All-female clubs In 1791, mid-way through the French Revolution, Etta Palm d’Aelders was responsible for the creation of the first club that was exclusively for females, known as the Society of Friends of the Truth7. Another club was formed in 1973 named the Society for Republican Revolutionary Women, which was created by Pauline Leon and Claire Lacombe. This club was strongly focused on the Revolution, and females who joined swore an oath of loyalty to the Republic and to the society. One argument that the co-founders of the society made was that women should have the right to bear arms and to govern. Less than five months af ter the society was first created a law was passed outlawing all women’s clubs8. Feminist movement During the French Revolution, the approaches that women took to their rights were significantly different, and can be broadly grouped into three categories. The first were theorists, such as Gouges, who focused on writing and on promoting the rights of women in general. The second group were female militants who believed that women should be heavily involved in fighting, and imagined armies of women battling against the enemies of the republic. The final group were

What is the role of British cinema Critically examine the contemporary Essay

What is the role of British cinema Critically examine the contemporary British film industry with reference to ongoing debates about culture and commerce - Essay Example It is possible to explore these aspects when considering two films to be able to understand the role of the British film industry in the society. One of the major concerns of researchers and officials is the commercial value of the British film industry. It has been estimated that the UK film industry contributes over  £4bn to the British economy annually (Statistical year book 2014). This is achieved through international investment and production grossing. In the first place, it is necessary to note that many British filmmakers â€Å"have complained that there is no UK ‘industry’ as such† (Branston & Stafford 2006, p. 437). Clearly, Hollywood is seen as a well-established and even exemplary film industry as it has penetrated the world as well as the British market. Consumers all over the world prefer Hollywood products (James 2009). At the same time, it is clear that Britain has also become an attractive destination for various foreign (especially American) companies. For instance, the country attracted more than  £1bn in 2010 (Branston & Stafford 2006). This interest shows a great potential of the c ountry and its film industry. To facilitate development of the UK film industry, the government implemented quite dramatic changes in the 2010s. For instance, the UK Film Council that functioned as a body supporting the development of the industry ceased to exist and the British Film Institute (FBI) is now performing its functions (Higson 2010). Thus, the government has launched a policy that is aimed at increasing funding of the industry. These changes and increased attention to the industry are also associated with a desire to contribute to development and promotion of the British culture. This is also regarded as a way to protect the country from globalisation and preserve its rich cultural heritage (Higson 2010). Of course, it is difficult to trace the line between commerce and culture especially when it comes to cinematography. Some argue

Essay question-Non-violent Example | Topics and Well Written Essays - 1500 words

Question-Non-violent - Essay Example On the other hand, revolutionaries such as Martin Luther King Jr., Dalai Lama and Mohandas Gandhi used non-violent means to include strikes, sit-ins and peaceful marches. Non-violent revolutions are normally characterized by the peaceful nature that they take rather than use of violence to get a reaction one expects. People who resolve to use this form of revolution often hope to set a better example to the future generations (Sharp, 2003, 183). If anything is to be determined from past revolution, one note that the society as a whole tends to benefit from non-violent revolutions than from violent revolutions. I do agree that non- violent revolutions work Non violence does not explicitly imply not partaking in violence; it can also be viewed as a way in which a person can use positive action as a way of resisting oppression and to bring about transformation in the community. Mahatma Gandhi once stated â€Å"The essence of non-violent technique is that it seeks to liquidate antagonisms but not the antagonists†. This can simply be interpreted to mean that non-violent revolutions aim to change the opponent’s point of view and win them over. It is a win-win situation. Revolutionists who use this method do so in inevitably they will be able to persuade their oppressors into seeing things from their perspective and that their point of view is right. Non violent participants do not seek out to harm their oppressors in any way. On the contrary, they are willing to suffer whatever it takes in order to bring about some form of change in the society. The reason as to why non-violence has such great fascination is because it removes the absurdity of trying to make the society more just and less violent place by using violence as a tool. If people are hoping to be a great leader, then it would be expected that they set the best

Technology Essay Example | Topics and Well Written Essays - 750 words - 7

Technology - Essay Example The technology age refers to the development, over time of several systematic techniques of doing and making things. The term technology was used, in the 17th century, to refer to the discussion of applied art only; gradually this art itself came to be the object of disintegration. Near the 20th century, the term had many meanings, processes and ideas, in addition to machines and tools. In the early 20th century, the term became common as most of technological developments took place in these times. There are many different uses of technology; the major and commonly applied area of technology is in communication (Hughes, 2009). Technology has been used to facilitate communication among people. Another use of technology is to provide the necessary security; a good example of such technology is that which is used, in airports and in the airplanes, to navigate aircrafts. Technology is used to make life easier, and it is manual. Companies also use technology to store information such tha t it becomes easy and efficient to locate and edit. Others use technology for entertainment purposes (Hughes, 2009). In the old days, all humans had a lifestyle that revolved around the development of tools and very few permanent settlements. The technology advancement then was to help humans to survive and get their food through hunting. Technology developments at that time were in the form of weapons and stone tools. Clothes were also among some of the major technology developments of that age. In the 21st century, main technological advancements are in the field of electronics. Biotechnology is also a relatively new field, which has undergone many developments. All the technology advancements of the 21st century have made our lives much easier and enjoyable (Colin & William, 2010). There are many different types and uses in technology. Technology can be divided several times according to the areas of use.

Civil Engineering Essay Example for Free

Civil Engineering Essay The material used for construction or the materials used to produce other materials which may be used in construction is called construction material. construction material are: Cement,sand ,water. Concrete, Lime, Stones, Paints and Varnishes, Wood and Timber, Engineering Metals, Bituminous materials and Plastics, Rubber and Glass, Miscelleneous materials, http://www.aboutcivil.org/engineering-materials.html Cement Bricklayer Joseph Asp din of Leeds, England first made portland cement early in the 19th century by burning powdered limestone and clay in his kitchen stove. Portland cement, the basic ingredient of concrete, is a closely controlled chemical combination of calcium, silicon, aluminum, iron and small amounts of other ingredients sand to which gypsum is added in the final grinding process to regulate the setting time of the concrete. Lime and silica make up about 85% of the mass. Common among the materials used in its manufacture are limestone, shells, and chalk or marl combined with shale, clay, slate or blast furnace slag, silica sand, and iron ore. Strength of cement Also known as the mother of all engineering, it is the oldest, most simple and useful of all engineering sciences. Civil engineering is field of engineering sciences, related to construction, design and maintenance of buildings, dams, bridges, tunnels, highways etc. sand Sand is an extremely needful material for the construction but this important material must be purchased with all care and vigilance. Sand which is used in the construction purpose must be clean, free from waste stones and impurities. It is important to know what type of sand is beneficial for construction purpose as sand is also classified into three different forms that make it suitable for specific type of construction. Sand is classified as: Fine Sand (0.075 to 0.425 mm), Medium Sand (0.425 to 2 mm) and Coarse Sand (2.0 to4.75 mm). However this classification of sand is further has types of sand in particular and on that basis only they are being incorporated in the construction. Read out the detailing of the types of sand: Pit Sand (Coarse sand) Pit sand is classified under coarse sand which is also called badarpur in common language. This type of coarse sand is procured from deep pits of abundant supply and it is generally in red-orange colour. The coarse grain is sharp, angular and certainly free from salts etc which is mostly employed in concreting. River Sand River sand is procured from river streams and banks and is fine in quality unlike pit sand. This type of sand has rounded grains generally in white-grey colour. River sand has many uses in the construction purpose such as plastering. Sea Sand As the name suggest, sea sand is taken from seas shores and it is generally in distinct brown colour with fine circular grains. Sea sand is avoided for the purpose construction of concrete structure and in engineering techniques because it contains salt which tends to absorb moisture from atmosphere and brings dampness. Eventually cement also loses its action when mixed with sea sand that is why it is only used for the local purpose instead of structural construction. There are different standards for the construction purpose which must be checked and considered for the better construction. The requirement according to which sand is chosen should be like: * For plastering purpose the overall fine sand used must not be less than 1.5 while silt is preferred to not less than 4 percent. * For brick work fine sand used must not be less than 1.2 to 1.5 and silt is preferred is 4 percent generally. * Concreting work require coarse sand in modulus of 2.5 to 3.5 with not less than 4 percent silt content. * http://www.sereneinteriors.com/building-construction/types-of-sand-construction.html water Pure and hygienic water is not only important for our life but also needed for quality construction. From the foundation till the completion of construction we must ensure the quality of water used. Here are few tips to know about water. Water is one of the most important elements in construction but people still ignore quality aspect of this element. The water is required for preparation of mortar, mixing of cement concrete and for curing work etc during construction work. The quality and quantity of water has much effect on the strength of mortar and cement concrete in construction work. Quality of Water The water used for mixing and curing should be clean and free from injurious quantities of alkalis, acid, oils, salt, sugar, organic materials, vegetable growth and other substances that may be deleterious to bricks, stone, concrete or steel. Potable water is generally considered satisfactory for mixing. The pH value of water should be not less than 6. Effects of Bad Quality Water on Cement Concrete It has been observed that certain common impurities in water affect the quality of mortar or concrete. Many times in spite of using best material i.e. cement, coarse sand, coarse aggregate etc. in cement concrete, required results are not achieved. Most of Engineers/Contractors think that there is something wrong in cement, but they do not consider quality of water being used. Some bad effects of water containing impurities are following. * Presence of salt in water such as Calcium Chloride, Iron Salts, inorganic salts and sodium etc. are so dangerous that they reduce initial strength of concrete and in some cases no strength can be achieved. There is rusting problem in steel provided in RCC. Â  Presence of acid, alkali, industrial waste, sanitary sewage and water with sugar also reduce the strength of concrete. ï‚ · Presence of silt or suspended particle in water has adverse effect on strength of concrete. Presence of oil such as linseed oil, vegetable oil or mineral oil in water above 2 % reduces the strength of concrete up to 25 %. 5. Presence of algae/vegetable growth in water used for mixing in cement concrete reduce of the strength of concrete considerably and also reduce the bond between cement paste and aggregate. Concrete. Concrete is a composite construction material composed primarily of aggregate, cement, and water. There are many formulations, which provide varied properties. The aggregate is generally a coarse gravel or crushed rocks such as limestone, or granite, along with a fine aggregate such as sand. The cement, commonly Portland cement, and other cementitious materials such as fly ash and slag cement, serve as a binder for the aggregate. Various chemical admixtures are also added to achieve varied properties. Water is then mixed with this dry composite, which enables it to be shaped (typically poured) and then solidified and hardened into rock-hard strength through a chemical process called hydration. The water reacts with the cement, which bonds the other components together, eventually creating a robust stone-like material. Concrete has relatively high compressive strength, but much lower tensile strength. For this reason it is usually reinforced with materials that are strong in tension ( often steel). Concrete can be damaged by many processes, such as the freezing of trapped water. Types of Concrete. Mix design Modern concrete mix designs can be complex. The choice of a concrete mix depends on the need of the project both in terms of strength and appearance and in relation to local legislation and building codes. The design begins by determining the requirements of the concrete. These requirements take into consideration the weather conditions that the concrete will be exposed to in service, and the required design strength. The compressive strength of a concrete is determined by taking standard molded, standard-cured cylinder samples. Many factors need to be taken into account, from the cost of the various additives and aggregates, to the trade offs between, the slump for easy mixing and placement and ultimate performance. A mix is then designed using cement (Portland or other cementitious material), coarse and fine aggregates, water and chemical admixtures. The method of mixing will also be specified, as well as conditions that it may be used in. This allows a user of the concrete to be confident that the structure will perform properly. Various types of concrete have been developed for specialist application and have become known by these names.. Concrete mixes can also be designed using software programs. Such software provide the user an opportunity to select their preferred method of mix design and enter the material data to arrive at proper mix designs. Old concrete recipes Concrete has been used since ancient times. Regular Roman concrete for example was made from volcanic ash (pozzolana), and hydrated lime. Roman concrete was superior from other concrete recipes (for example, those consisting of only sand and lime)[1] used by other nations. Besides volcanic ash for making regular Roman concrete, brick dust can also be utilized. Besides regular Roman concrete, the Romans also invented hydraulic concrete, which they made from volcanic ash and clay. Modern concrete Regular concrete is the lay term describing concrete that is produced by following the mixing instructions that are commonly published on packets of cement, typically using sand or other common material as the aggregate, and often mixed in improvised containers. The ingredients in any particular mix depends on the nature of the application. Regular concrete can typically withstand a pressure from about 10 MPa (1450 psi) to 40 MPa (5800 psi), with lighter duty uses such as blinding concrete having a much lower MPa rating than structural concrete. Many types of pre-mixed concrete are available which include powdered cement mixed with an aggregate, needing only water. Typically, a batch of concrete can be made by using 1 part Portland cement, 2 parts dry sand, 3 parts dry stone, 1/2 part water. The parts are in terms of weight – not volume. For example, 1-cubic-foot (0.028 m3) of concrete would be made using 22 lb (10.0 kg) cement, 10 lb (4.5 kg) water, 41 lb (19 kg) dry sand, 70 lb (32 kg) dry stone (1/2 to 3/4 stone). This would make 1-cubic-foot (0.028 m3) of concrete and would weigh about 143 lb (65 kg). The sand should be mortar or brick sand (washed and filtered if possible) and the stone should be washed if possible. Organic materials (leaves, twigs, etc.) should be removed from the sand and stone to ensure the highest strength. High-strength concrete High-strength concrete has a compressive strength greater than 40 MPa (5800 psi). High-strength concrete is made by lowering the water-cement (W/C) ratio to 0.35 or lower. Often silica fume is added to prevent the formation of free calcium hydroxide crystals in the cement matrix, which might reduce the strength at the cement-aggregate bond. Low W/C ratios and the use of silica fume make concrete mixes significantly less workable, which is particularly likely to be a problem in high-strength concrete applications where dense rebar cages are likely to be used. To compensate for the reduced workability, superplasticizers are commonly added to high-strength mixtures. Aggregate must be selected carefully for high-strength mixes, as weaker aggregates may not be strong enough to resist the loads imposed on the concrete and cause failure to start in the aggregate rather than in the matrix or at a void, as normally occurs in regular concrete. In some applications of high-strength concrete the design criterion is the elastic modulus rather than the ultimate compressive strength. Stamped concrete Stamped concrete is an architectural concrete which has a superior surface finish. After a concrete floor has been laid, floor hardeners (can be pigmented) are impregnated on the surface and a mold which may be textured to replicate a stone / brick or even wood is stamped on to give an attractive textured surface finish. After sufficient hardening the surface is cleaned and generally sealed to give a protection. The wear resistance of stamped concrete is generally excellent and hence found in applications like parking lots, pavements, walkways etc. High-performance concrete High-performance concrete (HPC) is a relatively new term used to describe concrete that conforms to a set of standards above those of the most common applications, but not limited to strength. While all high-strength concrete is also high-performance, not all high-performance concrete is high-strength. Some examples of such standards currently used in relation to HPC are: Properties of concrete. Uses of concrete. Concrete is widely used for making architectural structures, foundations, brick/block walls, pavements, bridges/overpasses, motorways/roads, runways, parking structures, dams, pools/reservoirs, pipes, footings for gates, fences and poles and even boats. Famous concrete structures include the Burj Khalifa (worlds tallest building), the Hoover Dam, the Panama Canaland the Roman Pantheon. Lime. Manufacture of lime Lime stones are burnt in either clamps or kilns.1. Clamps:For small quantity of limestone, burning is done in a clamp. On a clear surface about 5 meters in diameter, layers of broken limestones and fuel are laid to form a heap about 4 meters high.First and the last layers should be of the fuel. In case coal is used as fuel, it could be well mixed up with limestones and lay in a heap. Sides of the heap, which incline slightly inwards, are plastered over with mud to stop loss of heat. A little opening at the top is provided for draught. The clamp is then fired at the bottom.Disappearance of blue flame at the top is an indication of the burning of lime having completed. The clamp is then allowed to cool down and pieces of quick lime are then handpicked.Clamp burning of lime is uneconomical as the fuel consumption is more due to loss of heat and as some lime powder is lost in fuel ash. Also the quick lime carries any admixture of ash.| 2. Kiln for large quantity of lime, permanent structures of kilns are constructed.A. Intermittent kiln:Whenever the lime is desired intermittently or the supply of stones or fuel is not regular then the intermittent kiln is used. An intermittent kiln in which the fuel is not in contact with the lime is shown in the figure.Big pieces of limestones are used to make a sort of archon with which smaller pieces of limestone are loaded. Fire is lighted below the arch formed with big pieces of limestone. It is only the flame not the fuel that comes in contact with the stones. Burning should be gradual so that the stones forming the arch do not get split. It normally takes two days to burn and one day to cool the charge. B. Continuous kiln:Wood or charcoal could be used as a fuel. Limestones or kankars free from earth or impurities are broken into small pieces to about 5cm gauge. Alternate layers of 75 mm stone and 6mm coal dust are fed into the kiln. Top should be covered with mud, leaving a hole of 0.5 meter diameter in the center. Burning proceeds continuously and the kiln is not allowed to cool down. Burnt material is drawn out daily and fresh charge of stone and fuel is added from top. Over burnt pieces are discarded whereas the under burnt ones are reloaded into the kiln. Remaining material is slaked or ground in grinding mill for use. | a. Eminently rich lime: It slakes rapidly. It consists of less than 5% of impurities such as silica and alumina (in clay form) and high %age of CaO. It is slow in setting and hardening and setting depends on CO2 from atmosphere, therefore rich lime is used for plastering but not mortar making. It may be used for inferior and temporary structures. B. Lean and poor lime: It contains more than 5% clayey impurities and other impurities like silica, alumina, iron and magnesium oxides, exceeds 11%. Due to large amount of impurities it slakes slowly. It also sets and hardens very slowly. It is used both for plastering and mortar making for inferior class of work. Advertisements| 1. Composition:Fat lime is produced from sea shell, coral deposits etc or from lime stone containing impurities like free sand and soluble silica combined with alumina, magnesium, carbonate etc. If the proportion of free sand is large, the resulting lime becomes progressively poor and is called poor or lean lime.2. Behavior in slaking:Fat lime slakes rapidly when water is added giving out considerable heat and making hissing and cracking noise and increases 2 to 3 times its original volume. Fat lime if exposed to air, it absorbs moisture and CO2 from the atmosphere and becomes inert CaCO3 or chalk again and loses its cementing power. For developing the cementing power, quick lime must be slaked with water as early as possible, after it is obtained from the kiln.| 3. Shrinking:Fat lime has a greater tendency to shrink and crack as it dries. To prevent this, a large quantity of sand (2 to 3 times) must be mixed with it to prepare mortar.4. Hardening or setting:Fat lime is hydrated calcium oxide and sets by the absorption of CO2 from the air.Ca (OH) 2 + CO2 == CaCO3 + H2OCrystals of CaCO3 are formed and the water goes by evaporation. Thus fat lime hardens only where it comes in contact with air, as in plaster work.In the interior of thick walls, it does not acquire strength as CO2 i.e. air cannot reach there. Mixing of sand (2 to 3 times) forms pores for access of CO2 and helps hardening.5. Strength:Crystals of CaCO3 formed by fat lime are not very strong. Fat lime, therefore, does not possess much strength and is used for plastering walls, while washing etc in exposed positions.
