Gene Therapy :: Genetics Genetic Engineering Essays

Gene Therapy Gene therapy, the process of inserting a gene into an organism to replace or repair gene function to treat a disease or genetic defect, has made headlines world wide over the past several years as the new cutting edge technique that has the potential to change the way we look at medicine and treat people. Gene therapy is a method of treating inherited diseases by inserting copies of genes into the cells of affected individuals. The current research on gene therapy has centered on targeting somatic cells, such as red blood cells and nerve cells. Another approach, called germ-line gene therapy, would insert new genes into egg cells, sperm cells, or even developing embryos. These genetic modifications would be passed on to future generations.10 The ability to alter genes bestows upon humanity incredible power. With gene therapy, diseases will be able to be treated before children are even born. However, with such treatment, a slippery slope is not far off. If it is considered good to treat a fetus with genetic defects in utero, then it is not a large logical leap to allow a couple to engineer the â€Å"perfect† child that they have always dreamed about having. With the dawn of designer children, the control of evolution could be in the hands of those willing to pay for it. As disparities in healthcare continue to grow, those who could not afford gene therapy could become marginalized, and humanity could witness the establishment of a genetic elite. The potential for new forms of genetic discrimination is also great. The gene pool could be systematically cleansed of traits deemed undesirable. Is it ethical to tamper with an individual's set of genetic instructions? If so, where do we draw the line?9 In the fall of 1999, the ethical issues surrounding gene therapy came to the forefront of the field with the first death of a gene therapy patient, Jesse Gelsinger.1 Gene therapy may contain inherent dangers that are not always obvious at first glance, as was illustrated more recently in a gene therapy trial involving SCIDs victims. Consequently, several new standards for gene therapy have been put into place regulating gene transfer trials to improve patient safety.

Differences Between Men and Women Essay -- Compare Contrast Gender Ess

Anytime anyone is about to have a baby the first question is "Is it a boy or a girl?" People ask this question because there is a difference between the two genders. Several are curious to know whether the baby will turn out to be a sweet young lady or a strong young man. Even as children, the distinctions are obvious and stand apart. A young girl may ask a boy "What's that?" A young boy may ask a girl "Where's yours?" This is their first step towards self discovery. Everyone knows there is a difference but no one ever stops to see how many there truly are. There are numerous reasons why someone has become the gender they are, which is why the two appear different. Various people have been in the fight for equality over the years, they argue that even though we are all so different we can all be treated in the same way. In spite of the need for equality among men and women, there are still many differences, such as, body image, mate selection, sexuality, and ste reotypes. In selecting a mate, women look at different attractions than a man would. According to Rachel Herz, women are greatly attracted to the way a man smells and is typically one of the first things a woman looks for when selecting a mate. As a first impression, women want to be put into a daze or mesmerized by the individual they have come into contact with. Gender is not the only factor that a woman looks for when selecting a mate. Many women go deeper and search for things, such as, race, ethnicity, age, and good providers (Our Bodies 186). These affect many women by the importance they bring to a relationship. Typically women are looking for someone that they can spend their lives with, therefore they look for the qualit... ...each gender; it all depends on how those viewpoints are used that determine the kind of person that is developed.

Mc Donald Case Analysis Essay

McDonaldis one of the leading fast food chain operating in more than 120 countries (Exhibit – 4) with more than 30000 restaurants. McDonald opened its first restaurant in 1955 in Illinois and started to grow rapidly serving around 47 million customers daily with more than 1. 5 million employees. As far as Indian markets is concerned it was a distant dream for any western fast food chains to enter India and serve Indian customers, the reason being distinct dietary habits and food preferences of Indian consumers. After 1990 when government of India came up with economic reforms that liberalized policies of foreign investments, established western fast food chains like KFC and PIZZA HUT rushed to the Indian market but McDonald spent about six years analysing the market before entering India. During the analysis phase McDonald first categorized its various Opportunities, threats, strengths & weaknesses in Indian market. The analysis came up with the results like: increase in the purchasing power of individuals, their dietary habits like opposition to pork and beef and more inclination towards vegetarian foods, increase in urbanization and socio cultural habits. Depending on the results from the analysis McDonald came up with effective market mix (4Ps) that helped them to utilise the opportunities and thus eliminating the threats. The major highlight of the strategies adopted by McDonald was: Indianizing the menu and thus eliminating beef and pork completely, wide variety of products with different prices, confining itself to urban cities and building strong brand equity through various CSR events. This case analysis basically gives the overview of different strategies adopted by McDonald to establish themselves in Indian market. STRUCTURE OF THE CASE ANALYSIS (1) Market Analysis External Environmental Internal Environmental Analysis Analysis (Strengths & weaknesses) Micro Analysis Macro Analysis (Opportunities and Threats(PESTLE Analysis) for a new entrant in Indian Political food industry ) Economical Socio-cultural (2) Market Segmentation, Targeting and Positioning (3) Market Strategies (4P’s) (4) Outcomes MARKET ANALYSIS Market analysis done by McDonald’s during 1990’s included various aspects of Indian market and consumer. Looking at the data we can classify the analysis into external analysis and internal analysis. (1) EXTERNAL ANALYSIS Further divided into macro analysis and micro analysis. (a) MACRO ANALYSIS: Macro analysis takes Political, Economical, Socio-cultural, Technical, Legal and Environmental issues in consideration, but as per given case study, we are taking only 3 issues Political, Economical and Socio-cultural. Political: Liberalisation of policies: Liberalisation of policies paved path for MNC’s to India. Change in polices regarding in-flow of foreign capital and technology; government fixed exchange-rate eased up the process for MNC’s. Economical: Growth in GDP: The GDP growth until 1990’s was around 3% but after liberalisation the growth rate was around 6 to 7%, which shows increase in purchasing power of the individual. Socio-cultural: Acceptance of western culture: There was a significant change in the thinking of people towards western companies and western culture . The increase in use of internet is an example of this. Eat-out tradition began to grow very fast with increase in working parent families. McDonald’s internal analysis can be braked-down into strength, weakness, opportunities and threats. (b) MICRO ANALYSIS: Opportunities: Increase in urban population from 21. 3% to 28. 1% (exhibit – 2) because of employment, education. Increase in eat-out culture and purchasing power of individual. 53% (Exhibit – 7) of a house hold income is spent on food and beverages. Threats: India has been a country of different cultures (5000 ethnic groups) each with its own food habits and cuisine. Even though the food preferences of Indians show that 80% are non-vegetarians only 17% of them were pork and beef eaters (Exhibit – 11). McDonald has a image of pork and beef serving restaurant which is a threat for it in India. (2) INTERNAL ANALYSIS (ANALYSIS OF THE COMPANY) Strength: One of the strengths of McDonald’s is its vast knowledge and expertise in various countries which helped it gain expertise in making a strong and efficient supply chain. This will once again help it in building a efficient supply chain in India. It also has established and good brand equity around the world. Weakness: Opposition in people for MNC’s was decreasing but yet prevailing. There was a need for McDonald’s to rebrand itself in Indian consumers. In order to develop an effective marketing strategy it was very important for McDonald to understand its target customers. It was necessary for them to first understand Indian market and its consumers to communicate itself to consumer market. Basically McDonalds segmented their product and services according to base of Demographic, Psychographic and Behavioural attributes. McDonald did the thorough research for six years and was able to do well because of keen understanding of the Indian economy. MARKET SEGMENTATION & TARGETING Market segmentation is dividing of single market into smaller segments. Segmentation makes it simpler to address the needs of smaller groups of consumer. Three different bases of segmentation done by McDonald in India: 1. Demographic Segmentation: McDonalds uses demographic segmentation strategy with age as the parameter. The main target segments are children, youth and the young urban family. It offers different products like happy meal which includes a free toy for kids. For families it has made different outlets and meals which are suitable for takeaways and drive-thru. It has also created a suitable environment for youngster to hang out with their friends and get their lunch. 2. Psychographic Segmentation: McDonald’s adopted themselves to the lifestyle of the Indian consumers. India has huge vegetarian population so McDonalds came up with an entirely different product for Indian customers like Mc Veggie burger and McAalootikki burger. As it is not considered religiously incorrect to eat beef in India, the menu has no beef dishes. They also made McDonald a fun place where young urban families can spend some quality time, while their children can enjoy every moment of McDonalds. 3. Behavioral Segmentation: McDonald targeted mostly occasions like Birthdays and started attracted many families to celebrate their kids birthday. They made many advertisement effort aimed directly at kids and younger generation to promote birthday parties at McDonald. As most young people in the cities like Mumbai, Delhi and Bangalore live in small overcrowded flats McDonalds has become a convenient place for birthday celebration. POSITIONING Positioning is an effort to influence consumer perception of a brand or product relative to the perception of competing brands or products. Its objective is to occupy a clear, unique, and advantageous position in the consumer’s mind. In India positioning of McDonalds has been directed as a Family restaurant. Then they started positioning according to the kids as well by introducing new advertising of toys with their products such as â€Å"Happy Meal†. Now youngster and adults havebecome so use to fast foods that McDonalds has also started to target them and try to position itself as a place for all. This may be also due to the fact that India has second largest population in the world and they adopted this approach and tried to position themselves according to this approach to increase sales and revenue. McDonalds therefore wanted to position itself as ‘Indian’ and a promoter of ‘family values and culture’, as well as being ‘comfortable and easy’. Simultaneously, the brand wanted to communicate that it was committed to maintaining a quality service, cleanliness and offering value for money. MARKETING MIX (4P’s) Market Strategies Opted By Mc Donald in India Coming on to Strategies, McDonald strictly followed the concept of 4Ps for extending their share in Indian fast food market. Looking upon all the aspects of 4Ps in details, following was the approach made by them to enter the market and successfully lead it since then. Product: Taking the food habits of Indians into consideration, Mc Donald Indianised 70% of their menu, which really helped them to successfully grab Indian population. Also keeping in mind the un-acceptance of beef and pork in India , they replaced it with mutton-based Maharaja Mac. The French fries served in India also did not contain beef tallow covering. They excluded egg from ice-creams and mayonnaise served and also introduced Indian flavoured ice-creams. Pricing: Mc Donald came up with wide range of products in terms of pricing for serving both the lower-middle and high socio-class of society. (Products ranging from Rs. 7 to Rs. 128) They charged Rs. 74 less than what they charged in US in almost every product. Their menu was 80% visual and 20% descriptive. They used to attract customer initially by low prices, then increased their prices by simply giving another name to the product, for example- McAlootikki changed to Veg. Surprise. Place: Mc Donald opened its first outlet in two of the most western culture exposed cities i. e. Delhi and Mumbai, then they targeted the national highways connecting these cities by collaborating with Bharat Petroleum Corporation Ltd. As a part of Quick Service Restaurant (QSR) business, McDonalds opened its outlets only within 500-Km radius of its main distribution centres. After that, they tapped into business of shopping mall, multiplexes, railways and bus stations. Promotion: They promoted their restaurant as â€Å"Third place† between work and home. They also introduced â€Å"Music Meal† in association with Coca-Cola India and Universal Music India. They celebrated Children’s Day week, organised Pulse Polio and camps. Fun zones and Lego toys for children Looking upon the belief of Indians in Karma Mc Donald introduced â€Å"Itch Karo Rich Bano†, where the consumers were given lucky coupons complementary with their meal which they scratched to get gifts. This was a part of their promotional strategy which really worked well in India. Outcome It is reasonable to say that MCDonald’s has achieved a decent success in India. McDonald’s with its strategies was able to increase its sales volume, which in turn got down the break even to five to seven years which is much favourable when compared with 12-13 years that it takes in foreign countries. It is also stated that McDonald’s achieved a decent success as it showed a 50% annual revenue growth since 1997. A survey by Synovate showed that 20% of young Indians between ages of 8 to 24 reported their preference for McDonald’s products, followed by Pizza Hut (11%) and then KFC(2%). Even after all these achievements it cannot be concluded that McDonald’s succeeded in India. McDonald’s growth in India remains uncertain.

Economic Recovery of the 1930s Essay

â€Å"The economic recovery of the 1930s can be explained entirely by the effects of the New Deal.† How valid is this view? In 1932 Franklin D Roosevelt won the presidential election as a response to the â€Å"Great American Depression† which saw the collapse of the USA’s economic life continuing throughout the 1930s as a result in the inadequate action of Presidents Calvin Coolidge and Henry Hoover to alleviate the sheer hardships that came with the depression. Roosevelt and the Democrats took a more interventionist approach to recover the economy, provide relief for the unemployed and enact reform in order to create a fairer society. â€Å"The economic recovery of the 1930s can be explained entirely by the effects of the New Deal.† The â€Å"New Deal† was the interventionist programme Roosevelt initiated to tackle the issue and is key in explaining the USA’s economic recovery of the 1930s and is split into two factors in order to determine the validity of the previous statement; the first hundred days known as the First New Deal and from1935 to 1937 known as the Second New Deal. However, there were other factors which were important in the recovery of the USA’s economy. The growing power of the Federal Government to defend these reforms. The rearmament in preparation for the Second World War that reduced unemployment and increased industrial production. However, it was Roosevelt himself that revitalised the economy as he went a long way to rebuild confidence with the American public. Therefore the New Deal was undoubtedly a considerable factor in explaining America’s economic recovery but other factors although associated with the New Deal were independently important in the economic recovery. The economic recovery of the 1930s can be explained by the First New Deal, to an extent. During the first 100 days of Roosevelt’s office a flood of new legislation most becoming laws quickly providing relief and recovery. This meant that â€Å"Alphabet Agencies† were established and run by groups of Americans known as â€Å"The Brain Trust† in order to carry out work in tackling relief and recovery. The National Industrial Recovery Act passed on the 16th of June 1933 introduced joint economic planning between the Government and industry to stabilise prices, expand purchasing power, relive unemployment and improve working conditions. This was important as it represented greater government intervention in regulating and planning the country meaning that businesses would return to a living rate again by address issues such as  banking and lack of intervention which were initial kick-starters of the depression. The Public works Administration created jobs for unemp loyed industrial workers through large scale work schemes such as building schools, hospitals and parks which were of public benefit. This was effective in providing both relief and recovery as it created jobs for industrial workers as well as assisting the recovery of the economy by building necessary institutes for a functional economic system. Finally the Work Progress Administration (WPA), aimed to offer carefully chosen jobs that would be beneficial to the individuals community and was one of the most effective agencies. The WPA was one of the country’s largest employers between 1935 and 1941 at a staggering 2 million per year particularly employing the unskilled into large building schemes but also artists, actors and photographers into civic duties. Additionally around 11,000 schools and public buildings had been built nationwide along with 43,000 miles of road. This was important as the number of unemployed people significantly decreased which in turn led to an improvement to the economy as the employed raised revenue through taxation and because people would soon be purchasing more goods from important trades as the wages were respectable. However, the WPA only employed people for a year meaning that people would become unemployed again leading to a fall in investment into the economy taking the USA back to square one. Overall the First New Deal was successful in providing emergency relief and recovery as after the 100 days; national income rose by 23%, unemployment dropped by 2 million and factory wages rose. The impact of it was felt by millions and the money people were making meant that they began spending which brought the nation’s trade and business back to life, this was referred to as â€Å"priming the pump† as the Government’s spending fuelled the nation’s economic machinery and it started to move again. However, Roosevelt’s measures were being challenged in court and many were declared as unconstitutional and therefore illegal, restricting the progress and impact the New Deal could have. Additionally The First New Deal focused more on relief and less on reform and recovery which had shortcomings so it can be criticised for not being more radical and completely changing the USA and therefore cannot explain the economic recovery of the 1930s as factor more work needed to be done through The Second New Deal and other factors. The Second New Deal can also explain the economic recovery of the 1930s to an extent. By, 1935 Roosevelt’s New Deal was being greatly challenged by the courts and a newer more radical House of Representative, in order to solve this issue Roosevelt started over and produced a new flood of legislation. This legislation was more extensive than before and aimed to radically change the USA by focusing towards socio-economic reformation by improving long term living and working conditions due to the widening gap between the rich and poor which contributed market saturation. The social security act of 1935 provided a state pension scheme for the old, widowed, and disabled as well as poor children with payments ranging from $10 to $85 a month, paid from taxes on earnings and employer’s profits. This was important as it was the first attempt to provide for those at the highest risk of falling into poverty and it was the longest lasting New Deal. However, Welfare legislation lagged behind Europe as only 24 out of the 48 states at the time had old age pensions. Additionally there were wide gaps in payments between different states. The National Labour Relations act of 1935 gave the right of union to workers. This was important as the Government became integrated into industrial relations and resulted in the exponential increase of union membership and power. Finally The Wealth act of 1935 sought to raise revenue for the New Deals by now targeting wealthy with taxes, referred to by William Randolph as â€Å"soak the successful†. However very little was raised as loopholes were exploited by the most elite lawyers as the wealthy could afford them. Overall was a successful response to the opposition he faced from the courts. However, the issue remains that Roosevelt was attempting to radically change socio-economic situation in the USA at the expense of the rich and this reform promised by The Second New Deal was not fulfilled to an entirety. Therefore The Second New Deal and as an extension the first did cannot entirely explain the USA’s economic recovery although it undoubtedly contributed and helped other factors such as the increased power of The Federal Government which the New Deals helped to increase though they stand by themselves individually to explain the recovery. The increased power and role of the Federal Government in social and economic affairs was another important factor in the overall explanation of the USA’s  economic recovery. During this period Roosevelt’s New Deals faced opposition which led to Roosevelt using methods to challenge them as he believed he was elected to save big business and was disappointed by their lack of support. In 1944 Congress opposed to the Farm Security Administration of 1935 after it had already helped to settle 11,000 families and provided 41,000 long-term low interest loans to help tenants and sharecroppers purchase their own farms due to its provision of medical schemes for black and white migrants. Although a result of prejudices and partly a result of the New Deal this shows the increased role of the Government in deeming the act illegal and the act making it to that point on the New Deals part. Additionally it highlights how the success of the New Deal may have been restricted. In order to stop the Supreme Court, Roosevelt himself put forward the Judicial Reform act which appointed six additional judges that agreed with him to the pre-existing nine in order to help with the workload. This was important as the power he exerted over the Supreme Court, meant resistance to the New Deals was reduced increasing the power of the executive branch which aided the alphabet agencies’ progress in economic recovery. It also meant that people began to look more towards the Federal Government for help instead of the State Government. However, the judges were aware of this and restricted their duties. Overall the expanding role of Federal Government can explain the economic recovery of the 1930s as it gave the executive more powers to pass legislation that would improve the economy such as the New Deal particularly the survival of the Social Security Act and people look towards the federal government which increased their role in society which meant they could work towards economic recovery. Therefore the success of the New Deal is a result of this increased executive branch presence as it allowed Roosevelt to pass them, meaning that the New Deals alone can’t entirely explain the USA’s economic recovery. However, it was Roosevelt’s efforts in renewing the public’s confidence that explained the economic recovery as the New Deal would not have been successful in motion or in the legislative process without the support of the public. Arguably Roosevelt’s efforts in building the public’s confidence in the Government and its role in the economy explained the economic recovery of  the 1930s almost to an entirety as the New Deal carried some of the confidence. Roosevelt was popular among the public as they believed he cared about them as he was the first president to speak to the dispossessed and the have-nots in society, for example he spoke to those who had concerns with the Government regulating banks as part of the New Deal by ensuring their safety in using them. He said, â€Å"I can assure you that it safer to keep your money in a reopened bank than under your mattress.† Thousands wrote letters to him to show their appreciation. This was important as Roosevelt’s popularity among the electorate meant he won four presidential elections and the Democrats were voted into both Houses of Congress with a secure majority of 2/3 in the senate and  ¾ in the House of Representatives proving his popularity. This meant he was able to increase the role of Federal Government and improve the economy as he could only pass the New Deals with the support of the electorate and have them contribute to the economy with their confidence in the system as prior to him showing care the public were suspicious. However, not all of the elected Democrats agreed with the New Deal for example Ed Johnson who strongly disagreed with it saying it was â€Å"the worst fraud perpetuated on the American people.† Roosevelt also appointed an unprecedented amount of Catholics, Jews, blacks and women and used radio to keep the public updated. This was important as Roosevelt was appealing to minority groups which at the time were having severe problems and including the public in political affairs meaning that they would back the New Deal which would ultimately improve the USA’s economic situation and it made important social changes to minorities which were affected by poverty the most therefore improvi ng their economic status was vital in economic reform. Therefore the confidence that the public had in Roosevelt and the Government in addressing social reform explains the economic recovery during the 1930s as the backing he received was vital in the passing of the New Deals as he spoke to them like no other president which meant he remained in office for four terms and had more powers to pass acts in order to recover the economy. This means that the other factors would not have had any impact without the support he had from a public confident that he could save the economy. Therefore the New Deals do not explain the economic recovery of the 1930s entirely as there were more important factors alone and that affected the New Deals themselves, particularly the  confidence in the economic system that Roosevelt worked hard to build. However, there were still shortcomings of the legislation passed by the New Deal as a result of this confidence, which the Second World War helped in the USA’s economic recovery. An additional, important factor to be considered in explaining the economic reform of the 1930s was the rearmament in preparation for the war. In 1937 a new, less severe depression had arisen because Roosevelt had cut the federal Government’s spending budget causing a fall in the stock market and industrial production as well as a 4 million rise in unemployment. In response to the outbreak of war out with the USA Roosevelt convinced Congress to invest billions in National defence, improving the economy as he increased the wages of military personnel and offered subsidies for defence manufacturing which proved effective as unemployment plummeted to 10% during the war. Additionally the conservation during the war saved money and the immigration particularly Jewish people from Germany to California led to an economic boom. This was important as the war Kick-started the economy as the increase in wages and economic production during the war lowered unemployment and improved the economy post war as this industrial boom continued. Overall this contributed greatly to the economic recovery of the 1930s meaning that the New Deal cannot not entirely explain this recovery. However, it stills stands that the confidence built by Roosevelt explains the economic recovery as though the end of the war saw the end to the Great Depression it was Roosevelt’s support that got him to investing in defence which began the war’s industrial production. Therefore the New Deal can only partially explain the economic recovery of the 1930s as though they provided relief, recovery and worked towards reform, the New Deal did not radically change the face of the USA which did happen later but not as a result of the New Deal. This means that the statement is invalid as though the New deal was undoubtedly a considerable factor in the USA’s economic recovery other factors were also important. The growing power and role of the Federal Government in economics meant that Roosevelt had the power to pass the acts of the New Deal and the public looked towards the Federal Government meaning economic recovery could be  initiated nationally. The rearmament in preparation for the Second World War was more important as it significantly reduced unemployment and increased industrial production which planted the seeds for a post-war economic boom ending the Great Depression. It was Roosevelt’s personal work in building public confidence in the economy which proved to be the most important factor as it provided Roosevelt with the support to remain in office, change the role of the Federal Government which in turn meant he could get backing from both Congress and the public to improve the economy and later invest in the war industries that without would have kept the depression going post-war.

Measuring the Creep of Lead

This laboratory explores the phenomenon of creep. Creep is a slow continuous deformation within a material in response to increasing time, a constant applied stress and an elevated temperature. Here in this laboratory lead is chosen as the test metal as it is shown to have poor resistance to creep and also has a relatively low melting temperature. Applications Engineers are interested in the creep properties and stability of materials when designing specific parts and assemblies. Creep machines such as the one used in the laboratory are used by Engineers to determine these material properties. Creep causes many problems to the Engineer in design. They need to determine that the materials they use will stay within the required creep limits for the lifetime of the component. Creep is particularly important in the design components that need to withstand high temperatures. Creep will occur in metals at a faster rate as the temperature increases. These design considerations fall into four different applications:[1] Displacement limited applications are where dimensions must be precise with small clearances and little error. The small clearances must be maintained at high temperatures. An example of this type of application is in the turbine rotors of jet engines. Rupture limited applications are where precise dimensions are not particularly essential. However it is essential that fracture cannot occur to the material. An example of this is the need for high pressure steam tubes and pipes to withstand any break in their structure. Stress relaxation limited applications are needed where the initial tension in component relaxes with time. An example of where this application occurs is in the pretensioning of cables on bridges or in the pretensioning of bolts. Buckling limited applications of creep are needed in slender columns or panels which carry compressive loads. An example of this type of application would be in a structural steelwork that is exposed to fire. Objectives The objective is to witness the creep properties in lead. To achieve this creep tests are performed on lead specimens. Three creep tests are carried out using three different lead specimens. The load is varied in each of the three tests and observations are made on the results. Theory Creep Creep is a time dependent deformation that occurs under a constant applied load and temperature. The rate of creep is influenced by temperature and creep generally occurs at a high temperature. Creep then is a function of stress, time and temperature. The lowest temperature at which creep can occur in a given material is generally , where Tm is the melting temperature of the material in degrees Kelvin. Total engineering creep strain can be expressed by the following formula: Where ÃŽ µ is the theoretical stress, is the change in the materials length and is the materials original length. The strain rate describes the rate of change in the strain of a material with respect to time. Where is the strain rate; is the change in strain and is the change in time. The rate of deformation caused by creep is called the creep rate. The creep rate for a material with a constant stress and constant temperature can be calculated using the following formula: Steady State Creep Rate: Where Q is the activation energy; n is the stress exponent; A is a material constant; R it the universal gas constant and T is the temperature in degrees Kelvin. The activation energy Q can be determined experimentally, by plotting the natural log of creep rate against the reciprocal of temperature. The gradient of the subsequent slope is equal to. Fig. 1 – Natural log of strain rate against reciprocal of temperature. [2] For this experiment we are using a constant temperature for the three specimens. The Arrhenius equation can then be simplified to give a power law relationship: Where A is a constant that depends on the given material. Rearranging this equation the material constant A can be found: The value of A can also be found by plotting the natural log of the strain rates against the natural log of the applied stress values. Here the value of A is equal to the exponential of the intercept of the line created by this plot. The stress exponent n can be determined by plotting the natural log of the strain rate against the natural log of the applied stress. The gradient of this slope is equal to the stress exponent n. Fig. 2 – Natural log of strain rate against natural of applied stress [2] The stress component n is defined by the following equation: Stages of Creep Primary creep occurs at the initial stages of creep. In this stage the strain rate is relatively higher and then begins to gradually decrease. Secondary creep is also called the steady state creep stage. This occurs after the primary creep stage and the creep rate changes to a constant. In this stage there is no increase or decrease in the creep rate. Tertiary creep is the last stage of creep. The creep rate moves from the steady state of the secondary stage to a continuous increase. The creep rate progressively increases until the material reaches its breaking point and it ruptures. Materials Fig. 3 – Analogue Creep Testing Machine – Not used in experiment [3] * Lever-arm creep testing machine. * Various â€Å"dead-weight† masses. For this experiment there were 1.0, 1.2 and 1.4 kg masses. * Various lead creep specimens compatible with the creep testing machine. Similar to that in Fig. 4. * Linear Variable Displacement Transducer in contact with the lever. * Analogue to Digital convertor in the form of a PCI card. * Data logging computer program. * Computer. Because the creep testing machine uses a lever similar to that in Fig. 3, a mechanical advantage takes place. This needs to be taken into consideration when analysing the results. The lever in the creep testing machine in the experiment has an 8:1 mechanical advantage. The machine pictured in Fig. 3 uses an analogue dial for recording displacement. The creep testing machine used in this experiment uses an LVDT transducer. This is in contact with the lever and sends displacement data to the A/D card in the form of electrical signals. Fig. 4 – Lead Creep Specimen [4] Method * The three lead specimens are measured for their length and cross sectional area. For the first of the three tests, a 1kg load level is selected. * The top end of the first specimen is installed in the top grip of the creep testing machine. * The bottom end of the specimen is installed in the lower grip of the creep testing machine. * The creep testing machine is zeroed. In this experiment zeroing wasn’t possible so the recorded displacement results were offset by 6.039. This was remedied by adding 6.039 to all recorded displacements. * The data logger program is started while choosing an appropriate file name. For this experiment ‘data1.txt’ was chosen for the first specimen. * The load is now applied to the specimen in the creep machine. The data logger will record the elapsing time and the deformation in the specimen. * The specimen will eventually rupture due to the increasing creep and at this stage pressing stop in the program will end the logging. * For the second specimen a load of 1.2kg is selected. A different filename is chosen in the data logger program. For this experiment ‘data2.txt’ was chosen for the second specimen. * The process is repeated until the specimen fails. * For the third and last specimen a 1.4 kg load is chosen. Again a different filename is selected in the data logger program. For this experiment ‘data3.txt’ was chosen for the third specimen. * The process is repeated for the last time until the specimen fails. * The results are then analysed as described below. Results Fig. 5 – Specimen 1 – Strain against Time with 1kg Fig. 6 – Specimen 2 – Strain against Time with 1.2kg Fig. 7 – Specimen 3 – Strain against Time with 1.4kg Fig. 8- Specimen 1 – Strain Rate against Time with 1kg Fig. 9 – Specimen 2 – Strain Rate against Time with 1.2kg Fig. 10 – Specimen 3 – Strain Rate against Time with 1.4kg Fig. 11 – Table of Values Calculated from Experimental Results Fig. 12 – Natural log of strain rate against natural of applied stress – 3 specimens (a) Estimationis made of the maximum applied stress that the material can withstand considering creep of less than 1% per year. Assuming 31,536,000 seconds in a year: The slope of the line in Fig. 12 gives the value for n. The exponential of the intercept of the line in Fig. 12 gives the value for A. Subbing for A and n and rearranging: (b) Estimation is made for the maximum applied stress considering a total time to failure of more than 10 years. Again an assumption of 31,536,000 seconds in a year is taken. For the strain at failure an average was taken from the data for specimens 1 and 2, giving 13.134. Subbing in for A and n and rearranging: Discussion From looking at the strain against time graphs, Fig. 5, 6, & 7, the different stages of creep can clearly be seen. In the primary stage the strain rate is relatively high and this can be seen visually by the steeper slope at this section on the graph. The slope in the primary stage then begins to decline indicating a decrease in the strain rate. This is despite the applied stress and temperature remaining constant. This can be explained by strain hardening occurring in the lead due to dislocations in the crystalline structure. Looking at these graphs it can be seen that their slopes reduce further to a minimum and for a time stay nearly constant. This is a visual indication of the secondary stage in the creep process where the strain rate becomes nearly constant. Here there is a recovery process in the lead due to thermal softening. The recovery balances the effect of the strain hardening causing the strain to reach its steady state. At the right hand side of the same graphs it can be seen that the slope increases. In Fig. 6 and Fig. 7 this is shown more clearly where the slope increases exponentially. This increase in slope after the steady state is a visual indication of the tertiary stage in creep. The increased strain rate, as visualised by the increasing slope, is caused by necking. The necking begins due to local variations in stress concentrations in the specimen due to microscopic differences, defects or impurities. After the necking the cross-sectional area of the specimen decreases resulting in rapidly increasing stress concentrations. This increases the strain rate exponentially leading to fracture. In figures 8, 9 and 10 where the strain rate is graphed against time, the secondary creep stage can be seen more clearly. Here the steady state creep rate is visualised by a straight line with a value of y = 0. In the same graphs the secondary stage is bordered by two spikes in the strain rate. The left hand side has a smaller spike due to no work hardening having occurred and the specimens reacting to the applied load. The strain rate then decreases as discussed earlier. The right hand side shows a much larger spike due to the exponentially increasing strain rate caused by the necking. The stress component n is defined by the following equation: The stress component is then found by calculating the slope of against as seen in Fig.12. The material constant A can be found on the same graph by calculating the exponential of the intercept. Alternatively A can be found rearranging the power law equation: Fig. 14 – Theoretical values for A against the experimental value. In Fig. 14 it can be seen the values for A when using the power law equation compared against the value of found from Fig. 12. The differences are negligible and can be explained by errors as discussed below. The results of the experiment then confirms the steady state creep law. Errors If the masses are applied suddenly to the machine it will have a higher resulting stress on the specimen compared to a mass applied more gently. This is due to impact loading and will cause a higher deformation and creep in the specimen. The precision of the machine used in the experiment will have a result on the error. Also over time a machine needs to be calibrated. In this experiment it was not possible to calibrate the machine so this needed to be compensated in calculation later. Any vibrations on the machine or the LVDT will impact on the readings. This can occur through impact loading resulting in cyclical loading vibrations or it might be outside forces such as a table being moved. As discussed earlier, the creep rate is impacted by temperature. Changes in temperature due to draft or other influences could result in a change in the creep rate. No two lead specimens are exactly the same. There will be minor differences due to impurities in the metal or small defects such as notches caused by wear. Due to the manufacturing of the specimens there could be minor differences in their shape and area. All of these differences will have an impact on the results. Friction in the creep testing machine will resist the stresses caused by the â€Å"dead-weight† masses. Ideally this friction will be at a minimum, however some friction will always still remain and this will be a source of error. Most of this friction will be concentrated at the fulcrum of the lever arm on the creep testing machine. Electromagnetic interference in the electrical circuitry can impact on the recordings from the LVDT. Also any stray components in the system such as parasitic capacitances will also cause some interference. Rounding errors in the software or algorithm or later by the user will result in cumulative errors.

Cash Management Essay

Cash management techniques are an important part of managing finances. It is impossible to see your money grow if there are not methods in place to make the most of the money that you have. A good start to cash management is budgeting, which is the process of tracking money in and out to get a better idea of how money is really being spent. A budget identifies where the money is going and where adjustments can be made to decrease expenses or increase revenue. Along with budgeting, it is important to track expenses in order to know how much money is being spent. Expenses can be divided into categories such as office supplies, rent and utilities. Once you have the expenses clearly laid out ways to decrease the expenses can be found which will allow the company to save money. One easy way to save on office supplies is to buy in bulk or buy direct from a distributer. This will get you a lower price for the items then at retail store and can help save money. Another example is with companies that have vehicles. Gas companies offer discount cards which could be used with all their purchases to save money. Additionally, companies that operate fleets of vehicles may benefit from contracting with a gas supplier to get their gas at a greatly discounted rate. Investing is a great way to make your money generate more funds. This can be done by investing the money in various ways to allow it to generate interest. The more money you invest or the higher yield accounts that the money is in the more you will get in return. For individuals, investing in a 401(K) plan at work is a great way to save money for the future. This money can be deducted directly from the paycheck before it is received and invested into the account. Some companies will even match the money that is deposited into the account or match a percentage of the money. This helps the account grow even more. Having the money deducted from the paycheck before it is received is helpful because that money isn’t missed. It was taken out before the check was received and doesn’t have to be calculated into a family’s budget. Companies can invest their money into bonds which will generate interest and return for the company. Additionally, they could invest it in the stock market or other markets and savings accounts where they can get a return for the money. This helps the companies increase their cash and their wealth. In addition to investing, companies need to make sure they are collecting on accounts. When they have accounts that are past due, companies are losing money and this money needs to be regained. The accounting department of a company needs to keep close watch on the accounts and identify the ones that are not being paid. These accounts need to be collected in order to minimize the loss of income for the company. Lines of credit are necessary when there is a decrease in cash flow. This could be due to a slow month with a decrease in revenue or income as well as an increase in expenses. Companies and individuals need a way to cover expenses when the cash is limited. Credit plays an important role at this point. For the individual there are credit cards and home equity loans to help cover expenses when the cash isn’t available. These options however should be used sparingly as it is best not to use credit and credit can be maxed out if an individual is spending more than their income. Companies can use lines of credit to help cover additional expenses or regular expenses when cash flow is limited. One example of credit used by a company is a short term loan. This can provide the business with extra liquid cash that they can use to make ends meet at the time and will have to be paid back in the following months. Like with the individual, if a company is using loans frequently they will find themselves in debt and unable to repay it. At this point the company needs to reevaluate the structure of the company and identify ways to decrease their expenses. Generating additional income is important because you want to maximize the amount of money being brought in while minimizing the money going out. The individual person can maximize the money coming in by working extra hours at work or getting a second job. If a person has a unique skill they can market themselves in their free time to make money from that skill such as sewing or construction. Companies can generate more income by increasing marketing campaigns or expanding into new sales markets to generate more money in return.

Point of Presence Advertising Essay Example | Topics and Well Written Essays - 1000 words

Point of Presence Advertising - Essay Example The author planned to purchase a movie named Lord of the Rings - Fellowship of the Ring on recommendation of a friend and came across a pack of all the three movies of Lord of the Ring series at a price that was 20% less than the overall cost had the movies been purchased separately. The author realized that he anyway had to purchase the other two movies to complete the story and was delighted to get all the three of them at 20% discount. In the second purchase instance, the author was delighted to realize the value of the package as he owns both a Sony digital camera and Handy Cam. The total price was cheaper by 15%. Such product promotion advertisements resulted in positive impact on the author because the overall value of the buying decisions improved although the author didn't had planned for part of the purchase. The effectiveness of these two "Point-of-Sale" advertisements resulted in win-win deal for both the store and the author - the store increased the net sale value and th e author got more useful products at lesser cost. The author was not at all annoyed but was happy with the sales girl for introducing these offers. Massy and Frank (1966. pp383) presented the findings of an exploratory study on behavior of retailer advertising thus establishing some interesting empirical generalizations. They could prove that the brands sell differently in different stores and the support to a brand depends upon the brand's market share in a particular store type. The author discovered a linkage of this theory with the research by Kumar and Leone (1988. pp178-179) which stated that many customer packaged good manufacturers have resorted to funding short term sales promotion at the store level which primarily has two distinct advantages - the effectiveness of promotions can result in on the spot sales activity and the store management takes pride into participating in on the spot campaigns given increased margins & commissions. Both the manufacturer and the store management gain in this process - the former achieves brand promotion & quick sales and the latter achieves improved profitability of the store. Howeve r the store management normally achieves short term benefits but the manufacturers achieve long term benefits by achieving strong customer franchise through brand substitution. From the author's perspective one good observation about this model is that the on the spot promotional activities sometimes are effective enough to modify the purchase plan by the customers that they had made before visiting the store. Bucklin and Lattin (1991. pp24) observed that "point-of-purchase promotion is particularly attractive given the large pro-portion of grocery purchase decisions made after entering the store". They further observed that "two-thirds of supermarket purchases are the result of an in-store decision". Culturally speaking, such campaigns has promoted a culture of "fun buying" even avail such promotions to just find out what's hot on the day and carry out on the spot purchase decisions. Many a times, customers just get impressed by the sales skills of the sales person and do not bothe r what brand they are buying. Hence the
