Africa Diaspora - Research Paper Example Although the slaves significantly outnumbered their masters, they found it difficult to find their own voice outside their communities. The slaves suffered particularly harsh treatments if there were any attempts to gain emancipation or to run away (Bulliet, Crossley, Headrick, Hirsch& Johnson, 584). In the 1750’s, Mackandal  Ã¢â‚¬â€œ a voodoo priest with a charismatic personality was able to gather slaves into organized movements and networks throughout the plantations (Blackburn). He was also able to organize the maroon bands or runaway slaves. Even after his death in 1978, the movement continued to fight for the cause of the slaves. Concerned by this and by the disparity in the populations of the different groups, the European officials passed a number of laws that were not only discriminatory and oppressive of slaves but also of freed persons of color (Blackburn). These individuals were denied opportunities, were limited in the number of administrative positions that the y would be offered and were ostracized socially. Such laws motivated the freed slaves and others to join the protests. The French revolution led to the declaration of the Rights of Man in 1789, which declared all men to be equal (Blackburn). This was believed to be a vindication of their rights by the free colored population of Saint-Domingue. One such person was Vincent Oge who had recently returned from France. He believed that he and others like him had the right to vote in Saint-Domingue; and he perused this cause till he was captured in 1971 and brutally killed (Blackburn). This incident caused an uprising that was led by another voodoo priest Dutty Boukman. This uprising that started on 21st August 1791 led to the violent and disruptive revolt of slaves all over the province. In an attempt to curb the revolt, equal rights were granted to freedmen in 1792, but the war between France and England bought the rebels the support of the Spanish and the English (Bulliet et al., 584). The French realized that they could not fight on so many fronts, and so in 1794, the Assembly of the First Republic declared all slaves in the French colonies as free men. L'Ouverture  was a former slave who rose to the rank of commander in the army and worded tirelessly for the emancipation of slaves (Dubois, 171). These freed slaves were then encouraged to join the French army, thus serving as an incentive for the French to ensure emancipation of all slaves. These troops succeeded in defeating the Spanish and British invaders and gained command of the island where L'Ouverture declared himself a ruler and declared Saint-Domingue a sovereign black state in 1801 (Dubois, 177). This angered Napoleon Bonaparte who had L'Ouverture  captured. L'Ouverture  later died in prison in France. Napoleon sent Leclerc and Viscount of Rochambeau to take control of Saint-Domingue, where they tried to reestablish slavery without success (Dubois, 180). This fueled the revolt that continued to we aken France till it was defeated in 1803. Jean-Jacques Dessalines who was then leading the rebel forces in Saint-Domingue declared the state free on 1st January 1804 and renamed it as ‘Haiti† (Dubois, 303). The success of this revolution caused questions about slavery to be raised across the United States where slavery was still practiced. A number of freed men and slaves were inspired by the efforts of the rebels in Haiti and these voices caused political enquiry into the issues of slaves (Popkin, 298). American soil also saw refugees - both white and those of color - from Haiti

The relationship between ethics and politics Essay

The relationship between ethics and politics - Essay Example Your duty is to weigh the benefits and the harm of your actions. For example, the majority believes that it is entirely wrong and unacceptable to take the life of another. But if you saw a child’s life in danger and the only way that you could save the child was to take the life of another, it would not be unethical to do so, although standards of behaviour dictate that taking the life of another is wrong. Barak Obama: I believe that taking the life of another to save a child does not set a bad example and it reinforces our responsibility to protect children. However, stealing when you can easily ask for food or work for it sets a bad example and would not be acceptable by any standards of conduct. Socrates: Again it is about knowing what is good for you. I cannot be good for you to fail to save a child from eminent harm. Nor can it good for you to steal to feed a child. Moral realism dictates that ignorance is the only form of unethical behaviour. Rational man determines what he thinks is best in each situation. In this regard knowledge motivates action that is appropriate and false perceptions and beliefs motivate inappropriate conduct. Socrates: Not necessarily. There is a human inclination to be corrupted by power so that political institutions tend to be susceptible to timocracy, oligarchy, democracy and tyranny. None of these political institutions are capable of being impartial and are vulnerable to corruption. Socrates: Democracy gives that unsuitable ruler certain rights that permit him to remain in office longer than he should be. He has the right to insist upon a thorough investigation and he has the right to confront his accusers. Socrates: I would have thought that that fact that he was unsuitable would have already been a matter of public record. Still, I would have to say that democracy is the lesser of all the evils of politics. For instance, timocracy is authoritarian and can be compared to military

Progressive Education Essay Example | Topics and Well Written Essays - 750 words

Progressive Education - Essay Example Life and Death of the U.S. School System by Diane Ravitch This book is an excellent introduction to today’s education debates. The author sets forth a sound history of the American public school system, and after reading her book, the reader feels ready to consider opposing thoughts. Most importantly, they concur with her opinion that proper education is the foundation of America’s democracy. Readers are also likely to agree with Diane’s view that regardless of the measures which are adapted, education policy decisions should be well-informed and executed. Ravitch serves up an education reform like No Child Left Behind. She presents information showing that the policy was fruitless. For instance, she recounts Alan Bersin’s era as the administrator of the San Diego school. She uses his effort of re-structuring San Diego schools as a case of what happens when harsh, corporate-style management blunders into the world of learning (Ravitch, 2010). Black Teacher s on Teaching Black Teachers on Teaching is a truthful and convincing account of the philosophies and politics involved in the schooling of black children during the past half century (Foster, 1977). Michele Foster talks to those who were the foremost to school in unified southern schools and to others who taught in high urban districts, such as Los Angeles, Boston, as well as Philadelphia. The book is a perfect record in relation to the gains and losses accompanying unification of schools, the rewards and inspirations of teaching, and the challenges and solutions they observe in the coming days. The book answers the question of what black teachers between the 80’s and the year 2000 experience in teaching. The book is an excellent source of the reactions to school integrations and its outcomes to students, teachers and parents dating back to the 19th century (Foster, 1977). School in American Culture This book deals with culture as it is in the flesh of lively habituated bodi es of humans who frame the society which shares of their traditions. This is in terms of their words, their gestures and expectations. The book was set around the 40’s and 50’s. It is a brilliant example of the classical and realistic definition of culture, containing both practice and constituted selves. However, the practical report is not a study of the people in an American school, but rather an overview of discriminated places and people and their relations in daily activities. The book summarizes the American thought of a teacher, based on the time it was written, derived from both experiences and stereotypes. The analysis of a school though is not particularly based on summarizing stereotype so much as in a logical arrangement of evident schools (Mead, 1964). Puerto Rican Students in U.S. Schools Puerto Rican Students in U.S. Schools focus on the experiences past of Puerto Rican students in the United States. The book addresses issues of culture, identity, ethni city, language, social activism, gender, policy implications, and community involvement (Nieto, 2000). The book was set in the late 90’s, and was the earliest book to concentrate both on the education of Puerto Ricans in particular. It also focused on substantial and rising Puerto Rican scholars who are developing cutting-edge scholarship in the field of education. This volume is for anyone researching this vital

Diagnosis of Periodontal Disease Essay Example for Free

Diagnosis of Periodontal Disease Essay Periodontal disease is a disease that affects the gums which causes them not to hold on to the teeth as tight as is normal. The teeth are therefore detached from the jawbone as it (Dr. Pohlhaus, 2008). It has been found to be responsible for the majority of tooth loses among the adults especially if it stays unchecked over several years. The disease usually attack the tooth through a crevice referred to as sulcus that is found below the gum line. During the attack, the disease breaks down the attachment of the tissues with the tooth and this result into a pocket whose depth depends on the severity of the attack. There are two main categories of the periodontal diseases; the gingivitis, which is a milder form of the periodontal diseases and is usually reversible. The other category is the periodontists (http://www. ada. org/public/topics/periodontal_diseases. asp). The major difference between the two is that the latter affects only the connecting tissues and the bone while the former affects the gum and the bones without any interference whatsoever with the connective tissues. Periodontal disease is caused by a bacterium called plaque which attaches on the teeth surface. They produce some toxins the affect both the gums and its supporting tissues. If left for periods of up to two days, it hardens into a substance called tartar which then causes infection and inflammation of the gums, that is usually painless and can easily go unnoticed (http://www. emedicinehealth. com/periodontal_gum_disease/page2_em. htm# Periodontal%20(Gum)%20Disease%20Causes). Methods of Diagnosis of Periodontal Disease and their Impact During the diagnosis of periodontal disease, the qualified doctors do look at different parameters and are guided by some simple basic steps: He/She first seeks to know the medical history of the patient so as to know any present or past problems associated with the disease or any underlying infections that might be the contributing factor to the disease, and if the patient is under any medications. The doctor may also opt to inquire about the general home dental care quality. The doctor then proceeds to the part of physical examination where he inspects the gum for any abnormalities like redness and puffiness. This is then followed with periodic screening and recording, otherwise referred to as PSR, which helps to ascertain the severity of the infection after which the teeth movement is observed. Any movement shows loss of bone support. Finally, x-rays are carried out so as to see the structure of the bone supporting the teeth. In the modern times however, technological advances has not left behind the medical practitioners. The developments that have been experienced in the dental radiography have been on conventional radiography transmission that narrows down to the capture, enhancement, and analyses of images. This stands to correct the errors that were being committed by the human beings by their visual perception. These technologies therefore help in the improvement of the diagnosis, enhance the treatment procedures as well as streamlining of the transfer, storage and the retrieval of information. They also help provide backup to the data of the patient in case any unforeseen catastrophe like fire occurs. Over the years, focus has shifted to the use of subtraction radiography which helps to recognize any slight differences in terms of the densities and volumes of the bones over a period of time (Grondahl and Grondahl, 1983). This has been made possible due to the available digital imaging technology (Grondahl et al, 1983). When using this technology and for the results not to show any differences in the registration, the projection geometries need to be identical. Methods have also been developed that aim at reconstructing the images that do posses arbitrary geometric projections into projection geometry of the reference image (Dunn and Van der Stelt, 1992; Ruttimann et al, 1986; and Van der Stelt et al, 1989). Also, in hi report, they reported that some measurements of up to 16 mm translation errors with 160 angulation’s errors. It thus looked promising for the creation of important image pairs to be used in the subtractions radiology. Also, in 1986, Webber and Ohki et al (1988) found out about the use of software based, otherwise called â€Å"digital gamma correction†, as a corrective measure to the gray level image distribution which was a one major disadvantage of the subtraction radiography. Further improvement in technology helped make it possible to detect any changes in the density of the bones: using a calibration wedge whose attenuation properties are known, the density differences that are measured are changed into estimation volumes differences. Either hydroxyapatite or aluminum is used in this case due to the fact that their radiation attenuation positively compares to that of the bones in characteristics. When these anatomical abnormalities and other details as expressed on the radiographic images can be shown mathematically, then one can easily develop the computer algorithms which then will be able to automatically interpret the radiographs (Ruttimann et al.. , 1985; Van der Stelt et al.. , 1985; Benn, 1991). These procedures that are performed by the computers may be of great value to the medical practitioners in making their decisions since they add extra information to the assessment of the practitioners (Van der Stelt and Geraets, 1991).

Nestle Australia Is Food And Drink Products Supplier Marketing Essay 1- Introduction Launched in 1867, Nestle Australia Ltd is a supplier of food and drink products. It also provides a wide range of dairy milk products, noodles in many flavors, chocolate, frozen meals and coffees. Besides, it provides a variety of cold and hot drinks, light ice-creams and a variety of confectionery and bakery items. Nowadays, Nestle Australia offers catering services to cafes, restaurants, hotels and clubs.

Nestle provides also pets foods such as Purina. The company launched a joint venture with General Mills in more than 80 countries. (One Source, 2009) History At the beginning Henri Nestle has developed milk for babies who are unable to drink and to feed from their mothers, after five years this product was sold around the world as a food for babies and old people. In 1906, Australian market became the second largest market for Nestle and was served by many of retailers and sales agents. The best achievement in Australian market was in 1934 by the invention of new product MILO. (Nestle, 2009) Nowadays, this product is sold in more than 30 countries with sales of more than half Billion Australian dollar. In 1999, Nestlà ©s head office in Sydney became the headquarter for Oceania region which includes Australia, New Zealand and Pacific islands. Principles and Values In the whole life of Nestle (135 years), Nestlà ©s basic approach to business was the foundation and the maintenance of long term values for consumers, shareholders, employees, society and community as a whole. Nestlà ©s major principal is to maintain a long term business improvement and development. (Nestle, 2009). Nestles major values are the following: Long term development Long term relationships Integration and reacting with different cultures The identification that customers earn information about the company besides the product that they bought Ethical values are basic requirements for our employees and senior line managers These values and principles have been translated into more than forty languages around the world, and it is must that all Nestles mangers should recognize and apply these values in their career lives, and these values are given by training to the new employees. Nestle Australia Nestle also is participating in the Oceanias community which is identified by its mixture and diversity of economic conditions, cultures, believes and tastes. We became a vital part in the community in which we activate as an employer and as a supplier to the local area. Besides, we were the leaders in many issues such as people health and environmental protection. As the largest food and beverage company in the world, we believe that we have a responsibility to customers and we are taking this responsibility seriously. We believe that people should live in a healthy style by doing sports, we are sponsoring many sports events and we are always encouraging people to get active. In addition, through our agreement with the Australian Institute of Sport, we are improving children to get their knowledge and to understand nutrition. Mission Statement When you read Nestles mission statement the following words jump to your mind: Research, good food, health and wellness. Our products bring to consumers the best tastes and pleasures. Research is the masterpiece of Nestles heritage and an important element for our companys future. We still know that there is some mysterious information about health and wellness had not been discovered yet, that is the reason that we are still searching for answers to bring Good Food for Good life. (Research. Nestle, 2009). Nestle Worldwide Today, with more than 480 factories and 265,000 employees in 87 countries in all over the world: Americas, Africa, Middle East, Europe and Australasia, Nestle is considered as the largest food and Beverage Company all over the world. Nestle Oceania in Australia, New Zealand and the pacific island is hiring more than 5,500 employees, with more than 20 factories and four distribution centers owned and managed by the company. Due to Nestlà ©s multinational reputation, and despite the tough market conditions not only in Australia but worldwide, and due to Nestlà ©s convenient place in Sydney and due to the high qualified employees and the brilliant companys strategy, Nestle dad been ranked number one among all food suppliers in Australian market in 2008 (Nielsen Report, 2008). In 2008, for Ice-cream, yoghurt and coffees categories, Nestlà ©s sales volume was more than AU$200m for each category. 5% Employees Turnover Rate More than 6,000 Brands and 10,000 Products More than 480 Factories in 87 Countries Over than 265,000 Employees Annual Sales more than 103 A$ billion World Leading Food and Beverage Company Nestle Figure1, Nestle Worldwide. Source: Nestle, Australia, 2009. 2- Situation Analysis 2.1- Internal Analysis Nestle Australia is considering the market leader in food and beverage sector in Australian market with overall sales more than , involved in more than 20 industries such as: Chocolates, yoghurts, ice cream, milk, dairy deserts coffee , confectionery and frozen meals. Nestle Australia has launched more than one hundred brands; Coffee Mate, Nescafe, Uncle Tobys, Nesquik, Maggi, Drumstick, Quality Street and Peters are only examples of Nestlà ©s brands in Australian market. Referring to Nielsons 2008 report, Nestle was ranking high among its competitors in ice cream, milk and yogurt fields which could be a very good indicator for launching our new product that we will discuss later in our marketing plan. Referring to the Retail Australias 2009 grocery magazine we will find the following: For Chilled Diary category, Nestle value share was about 14.2% in 2008 comparing by 16.8% for the previous year. For Dairy Desserts Category, Nestle value share was 25.2% comparing by 25.3% for the previous year For Chilled Diary category, Nestle value share was about 14.2% in 2008 comparing by 16.8% for the previous year. For Yoghurt category, Nestle value share was 11.8% in 2008 comparing by 15.8% for the year above. For Drinking Yoghurt, Nestle is not involved in this market yet, only the following companies are in this market : Yakult, Jalna , Bulla and some other small companies. As an overall trend, we could realize some declination for Nestlà ©s volume trend in some industries and categories. This decrease was a natural impact of the huge affect of the global financial crisis as we will describe in the next chapter .Due to this crisis, customers might buy some products instead of Nestlà ©s ones or they might even reducing their purchases for some items. 2.2- Macro Environmental Analysis (PEST Analysis) Economic After several years of flourish and high economic growth, The Australian economy suffered a lot in 2008, due to the huge effects of the economic global financial crisis. Australians GDP is declined; a reduction in job vacancies and a high rate of inflation, all these indicators could lead to an increasing in food and beverages prices See figures 2 3 for Australias GDP and Unemployment Rate in 2007, 2008 and Jun 2009. (GDP growth reached 2.7% in Jun 2008 comparing by 4.3% in Jun 2007) Figure2 Australias Unemployment Rate- Source: ABS, 2009 Figure3: Australias GDP Growth rate- Source: ABS, 2009 Social Despite the lack of confidence for Australian consumers, Australia becomes one of the most optimistic countries, as in 2008, Australia was ranking as one of the most confident countries all over the world with an index score 104, 20 points higher than the world average.. (Nielsen, 2008). Generally Retail growth in 2008, 2009 stays slow, and consumers became more carefully with their money, they spend more money for dining at- home like buying foods and drinks from supermarkets and they spend less money for out of home activities like cafes, restaurant and take-away shops. Despite the fact that supermarkets gained a good share with this new customers philosophy, total grocery sales have been declined in 2008. (Nielsen, 2008). The total retail sales growth reached 5.9% in august 2008 comparing by 7.5% for the same month in 2007. Comparing by 2007, the businesses such as cafes restaurants and takeaway Foods, had recorded the largest drop in turnover of 6.4%. One expectation of these supermarkets is Aldi. Customers preferred to go to Aldi due to the good prices in addition to the good quality there. Aldi, with share reaching more than 22% , had took many dollars away from huge chain supermarkets. Politics This part indicates legal and political situation in Australia. It includes: Taxation for raw materials bought overseas, employment laws, environmental regulations, political stability and competition regulations. . In my opinion, no other politics issues would affect the launching of our new product due to the currently stable politic situation that Australia is facing now, i.e. there is no war, no revolution or even no elections are affecting Australia at this moment Technological Besides the innovation and application of new technology such as the RFID (The Radio Frequency Identification) , the increase in price of raw materials and other supply chain costs could affect the launching of our new product. 2.3 Micro Analysis The Market If we take an overall view on grocery market last year. Referring to the 2008 Nielsen report we will realize these important following items: -An overall declining trend in grocery market, with sales growth 5.9% comparing by 7.5% as we mentioned before, which is a normal consequences due to the new situation; consumers tightening their belts -.Drinks and confectionery are only the two sectors that have achieved an increase in growth for 2008, with 3.3% and 7.5% respectively. -The largest growth achieved was in dairy sector by increasing more than 7.6%. The most important sector in this report is the Chilled Diary , since our new product( which we will discuss it in this chapter) is a sub category for the Chilled Diary part. In 2008, and despite the financial crisis, this sector achieved an AU$996.5m grocery value with an increase of 3.5% comparing by 2007. This indicator could be a high motivation for Nestle to increase its market share in this category (See Figure 4 5) Figures 4 5 : Australias Chilled Diary Market Corporate % Shares for 2008 2007 . Source: Australias grocery magazine, 2009. Referring to the above data, we could recognize that there is a large advantage for Nestle to increase the profit by investing in confectionery or drinks sectors, especially in dairies products. The Product Our new product would be categorized under the Drinking Yoghurts category. (We will discuss the product briefly in the next two chapters). The Drinking Yoghurts value market in 2008 reached a A$52.3m with an increase of 5.5% comparing by 2007. This market contains only 3 major companies; Yakult with 67.7% value share (The market leader in this category) Jalna with 10.6% value share Bulla with 4% value share And Private Label with 16.8% value share. Figure 7, Australias Drinking Yoghurt Market Corporate % Shares 2008 Source: Australias grocery magazine, 2009 After all the above reasons, we could conclude that there is a big opportunity for Nestle to enter this market and it would obtain a very competitive position among the other competitors. Target Market and Market Size In this market plan we will focus on: children, youths and adults which are the majority of Australian population. We will concentrate on both genders male and female and our market will be in the whole Australia and not in a specific city. Australias population at the beginning of 2009 was 21,644,000 persons. The children aged population (0-14 years) was about 19.8% of the total population and the working age population was about 67.4% (15-64 years) of the total population. (OECD Fact book, 2008). However, in our market plan, we will exclude the: 0-4 and 40-65 years population which means that we will try to attract from 50-60% of Australias population. Undoubtedly, some of the 40-65 years population would use our product. However, they will not be potential customers as the mentioned ones. 2.4. S.W.O.T. Analysis -Strengths Market Leader in the industry Good quality image and high brand awareness A high growth rate in the desired market A huge product lines Parent Support An international team working behind the plans achievement A very-well trained employees in all companys department A supply chain management to serve the whole country Weakness New market forNestle Unstable economic conditions: Decline in GDP growth rate and high inflation and unemployment rate. Customers are tightening their belts Exciting competitors Opportunities A huge market size An identified target market No large multinational size competitors Increase in sales and profits Increase in total Australias market share Increase in product line An opportunity to export the product to many countries around the world Threats Segments are shared by competitors Uncertain circumstances could affect our sales Misunderstanding of the product Poor advertising campaign due to the market conditions An unexpected drop in the confectionery and drinks markets. 3-Product Launch The product launch is the most important part of this market plan. As we discussed in the previous chapter, we are going to launch a drinking yoghurt product. So why did we choose this product specifically? If we take a quick view on Nestle share value in yoghurt and chilled diary industry we would realize the following: In Chilled Diary category, Nestle value share was about 14.2% in 2008 comparing by 16.8% for the previous year. In Yoghurt category, Nestle value share was 11.8% in 2008 comparing by 15.8% for the year above. It is very easy to recognize that Nestle is facing a problem in these above sectors for the last year. We all know that all companies now are facing financial problems and markets are unstable and nowadays many customers are tightening their belts. However, these two markets had an increase in their value rate for the last year with 3.5% value increase for Chilled Diaries and 5.9% increase for yoghurt products comparing by 2007. (Australias Grocery Magazine, 2009) Also, referring to the Australias Grocery Magazine, some of Nestlà ©s competitors such as Diary framers had achieved an increase in value share According to the above, Nestle is facing a small problem in this market, so how to solve this problem? The answer is including many possibilities. We could reduce our prices, we could increase our market share by an increase in production, and we could modify our advertising and promotion activities. In addition, there is another plan. We could enlarge our share in Chilled Diary category by launching a new product in a subcategory which is the Drinking Yoghurts. If we achieve this plan we could gain a higher market share, increase our sales and profits, enter a new market segment and finally we will gain new customers. The Drinking Yoghurt market is facing a good condition these days; by an increasing 5.5% in value share in 2008 with a grocery value reached more than AU$50m , which means that this market is gaining new customers day by day and despite the unstable market situation, the drinking yoghurt market is in a developing trend. Nestle is already producing chilled diaries, yoghurts and fruit yoghurts so many product lines are ready for the launching of the new product. Also, Nestle is already gaining a high-ranking in the grocery market, therefore all shipping, transportation, supply chain, deliver products to supermarkets could be handled easily. Yoogo would be the brand name of our new product. We will launch the product at the beginning with three flavors; Yoogo Mango, Yoogo Strawberry and Yoogo Apricot. After three years of market and sales observation, we will launch a new Light Yoogo, which will be Fat Free drinking yoghurt for people who care more about their health and lifestyle. Yoogos ingredients could contain the following: Milk, Skim Milk, Fruit Preparation; mango or strawberry or apricot, and approved flavors and colors. Undoubtedly, Yoogo would face a high competition when it enters the market. ( We will discuss this later in the next two chapters). However , the main competitive brands would be yakult with 67.7% and Jalna with only 10.6% value shares in 2008. (Australias Grocery magazine, 2008). However, Nestle could produce the product and gain a high position among these brands. (We will discuss this later in the next two chapters). 4-Market Strategy Market Segmentation, Targeting and Positioning To gain a desirable position among all competitors in customers minds, we will segment our market on two bases: -Demographic Segmentation Geographic Segmentation Demographic Segmentation We are targeting customers depending on their ages. As we mentioned before, we will focus on: children, youths and adults which are the majority of Australian population, we will exclude the: 0-4 and 40-65 years population which means that we will try to attract from 50-60% of Australias population. This is a very huge segment as we are focusing on more than half of the countrys population. Furthermore, we believe that any of these segmented people, with any sex, income, occupation would use our product as it is not a luxury product using by specific customers. Undoubtedly, we will vary our advertising campaign for each generation, i.e. the advertising campaign for children will be different than the youths one. Otherwise, we will make a small bottle for children (150 ml) and a large one for adults (300ml). Geographic Segmentation We will divide Australia as geographically basis to zones and each distributor would be responsible for each zone. E.g. We will divide Australia to five zones: Vic, NSW, WA, SA and Queensland Each company when launching a new product desires a high profit margin, large sales volume, high growth rate. However, we will concentrate more in achieving a long-run high profit and sales instead of the short-run ones. We believe that there are some requirements for effective segmentation: Measurability, Accessibility, Substantiality and Actionability. (Kotler et al, 2007) Our team will work hard to meet all of these requirements We consider that we will face a huge competition and we will face also the threat of substitute products. However, we will do our best to cover our market targeting by maximum three years and to be the market leader for this category in maximum five years. Our plan is to gain more than 55% of supermarket shelves in five years. We realize that this is a very hard mission, but we will try to achieve it by three main steps: Understanding our marketing segments- Maintaining an advertising and promotion plans- -Launching Yoogo with a reasonable price according to the company and according to our consumers.(we will discuss the price part later in Marketing Mix Strategy) Also, we will try to gain a competitive position in customers minds based on the following two concepts: Nestle Family Brand The Nestle family brand is showing care and safety to consumers and this is a very good reason to attract the customer. Communication Due to Nestlà ©s brand name, it is very easy to be in touch.with our customers 5-Marketing Mix strategy: Product Our product is a Fruit drinking Yoghurt with three flavors; Mango, Strawberry and Apricot. We will make two sizes, 150 and 300 ml. The gradients would be described as following: Milk, Skim Milk, Fruit Preparation; mango or strawberry or apricot, and approved flavors and colors (We had discussed the product more briefly in chapter 3) Price In launching this product we could use one of these two pricing methods: Cost- based pricing: Calculating the price by adding a mark-up to the cost of the product. (Kotler et al, 2007) Going-rate pricing: Calculating the price basis on competitors prices, with less attention to our cost or to the market demand. (Kotler et al, 2007) Value-based pricing: Calculating the price basis on buyers perception of value, with less attention to the sellers cost. (Kotler et al, 2007). In Nestle, we use the cost-based pricing method: Unit cost = variable cost + (unit fixed cost à · unit sales) Unit price= unit cost à · (1- desired return on sales) We determine our prices basis of the following objectives: Profit: For any company the most important issue is the profit earning, however, as we are launching a new product, we do believe that we will not gain a high profit margin at least for the first three years Consumer Satisfaction: The most essential factor when determining the price is our customers satisfaction towards our products and prices. Place We will divide Australia to 5 zones; Victoria, NSW, SA, WA, and Queensland. However, we will try to promote Yoogo everywhere, in every small and large city in Australia. Customers will find Yoogo in hypermarkets such as Coles, Woolworths and Aldi, in medium size supermarkets such as IGA and even in small supermarkets such as Seven Eleven. Customers would find Yoogo in cafes, restaurants, hotels cinemas and beaches. In addition, Yoogo is a healthy fruity drink, so you can find it also at hospitals. This plan is a little bit hard to be achieved. However, with the well-established supply chain management in Nestle and with the very good relationships with suppliers, retailers and resellers, we could achieve this plan within maximum three years. Promotion Promotion is the activities that represent the value of the product and encourage customers to buy it. In our marketing campaign and promotion we will tray to reach every body every where. We will do advertising campaigns in newspapers, radio, streets and television. Seeing that the survey research is the most widely method for collecting primary data, before launching the product we will perform a marketing survey research; we will go to clubs, streets and schools. Also, we will implement an online marketing research to collect primary data through online focus groups, using the integration of animation such as; audio, video and virtual environment would help us to overcome any limitations. We will try to select a sample of the population that has been selected, ask those questions about the product and the company and depending on the results of this research, we will implement our advertising campaign. We will support our promotion campaign basis on these four methods: A-Individual Selling: In this campaign, we will implement a direct selling activity especially during the summer months of November, December, January and February. Our team will go to club and beaches to meet our target segments there, they will wear t-shirts and caps with Nestle and Yoogos logos, and they will sell our Yoogos 150 ml bottle. By applying this innovative idea, we hope that our brand will get a great vision in terms of image, sales and brand awareness. B-Sales Promotion: Besides personnel selling, we will implement some sales promotion plans. At the beginning of the product launching, we will go to streets and malls, we will offer free 150ml trial bottles to customers, we will encourage them to try our product and to give us their feedback by email or even by phone. In addition, we will offer a 150ml bottle free with the purchasing of three 300ml bottles. Adding to this trade promotion, we will give the retailer an addition discount 5% during our sales promotion. Our marketing team will implement a major healthy and education campaign about the importance of the product, our team will focus on the concept that our product is a healthy one. Invitations would be sent to parents of school children to attend these seminars. This could help us to improve our brands image in consumers minds. C-Public Relations: Public relation is one of the most important factors in all multinational companies promotions. Every year, Nestle is launching its annual report containing information for shareholders and stockholders. In addition, a large amount of information regarding our product and our promotion would be found in newsletters and magazines issued by Nestle Australia. This promotion would obviously lend a hand in formation of the awareness of our brand.

Basic Structures Of Ferrous Metals

Basic Structures Of Ferrous Metals Ferrous metals is mainly based on iron-carbon alloy with the combination of other alloys such as plain carbon steels, alloy, tools steels, stainless steels and cast iron. Alloys having iron with a valance of +2 are known as ferrous; those alloys which have iron with a valence of +3 are called as ferric. Ferrous metals or alloys are metals that contain the element iron in it. Depending on the end of use, metals can be simply cast into the finished part or cast into an intermediate form, such as an ingot, then worked, wrought by rolling, or processed by forging, extruding or another deformation process. All ferrous metals are magnetic. They contain a small quantity of other metals in order to give the correct properties. Manipulation of atom-to-atom relationships between iron, carbon and various alloying elements establishes the specific properties of ferrous metals. As atoms transform from one specific arrangement, or crystalline lattice, to another its gives good mechanical propertie s. Pure iron: It is also called as Pure Ferrite. The carbon content is calculated. From 0 to 0.5%.It has the BCC structure when it is in room temperature. Also known as Alpha iron. Plain Carbon Steel: Consists of iron containing small amounts of carbon. The carbon content can vary from 0.008% to approximately 2.0%. Low- Alloy steel: Steel containing alloy additions which usually do not exceed a total about 10% are referred to allow-alloy steels Ultra-High-Strength steel: Steel capable of developing yield strength greater than about 1104 Mpa are considered ultra-high-strength alloys. Medium-carbon low-alloy steel: These alloys consists of grades such as 4130,4330 and 4340, which can be quenched and tempered to yield strengths on the order of 1725 Mpa Maraging steel: This class of steel consists basically of extra-low-carbon (less than 0.3%) iron-based alloys to which a high percentage of nickel has been added. Corrosion-Resistant (stainless) steel: Stainless steel may be divided into four categories: ferritic, martencitic, austenitic, and age-hardenable. Ferritic stainless Steels: This group of stainless steel contains between 11.5 and 27% chromium as the only major alloying element in addition to a maximum of 0.25% carbon Martensitic stainless steels: This type of stainless steel is also primarily chromium steel, but in contrast to the ferritic group, consists enough carbon to produce martensite by quenching 0.15 and 0.75% carbons. Austenitic stainless steels: This Stainless Steel is alloyed to the extent that they remain austenitic at low temperatures. The principal alloying elements added to the chromium and nickel, generally totaling than 23% Precipitation-hardening stainless steels: The last class of stainless steel we will discuss depends on precipitation hardening for the optimum development of properties. Very high strength together with corrosion resistance Cast iron: Cast irons are iron-carbon-silicon alloys. More than 2% of carbon Grey cast-iron: Also known as graphite cast iron. They depend on the distribution size and amount of the graphite flakes and matrix structure. Spheroid graphite cast-iron: Also known as Ductile or nodular iron. It has high modulus of elasticity. Austempered Ductile iron: Recent addition to cast iron family, outstanding combination of high strength, toughness, wears resistance. Compacted cast iron: Referred as vermicular iron. Consists of 80% graphite and 20% spherodial graphite Malleable Cast iron: Carbons present as an irregular shaped nodules of graphite. Also classified as white heart malleable cast iron. Blackheart malleable cast iron.Pearlitie malleable cast iron Austentic carbon: They are high alloy cast iron. Mainly nickel in which carbon is present List of advantages These are materials with high specific strengths when compared with weight that is high strength to weight ratio. High quality materials exist in abundant quantities within earth’s crust and are readily available worldwide in various certificate grades. It increases the speed of construction in the field of civil engineering. Versatility;steel suits range of construction methods sequences. Modification repair can be easily done with left effort. Recycling can be done easily. Durability of these materials are very high Aesthetics;steel has a broad architectural possibilities Limitation of the material in engineering applications: The principal limitation of many ferrous alloys is their susceptibility to corrosion Costly waste as scrap High cost of final finishing polishing Environmental issuebecause of improper disposal Ferrous metals get rusted easily (oxidize) unless protected eg. with oil b) Non-ferrous metal Non-ferrous metals are metals other than iron and they do not contain an appreciable amount of iron in them. Non-ferrous metals are aluminum, magnesium, titanium alloys, copper, zinc and miscellaneous alloys like nickel, in, lead, zinc as base metals. The precious metals silver, gold and platinum are also coming under non-ferrous group. Non ferrous metals are alloys which are non magnetic. Non ferrous metals: Aluminum: Abundant element of 8% on earth crust and normally found in Oxide forms (Al2O3), i.e., bauxite, kaolinite, nepheline and alunite Aluminum base alloys: Aluminum is used in its commercially pure state as well as in its many alloy forms. The heat –treatable types have the advantage of being relatively easy to fabricate in their soft condition, after which they are heat treated to develop their higher strengths. Copper- base alloys: Copper is seldom industrially employed in its pure state. Copper has its most value when alloyed with other elements. It dissolves with elements such as tin, zinc, and silver in rather wide proportions. Magnesium – base alloys: Magnesium are noted for their lightness. The specific gravity of magnesium is 0.064 lb per cu.; in comparison, aluminum, steel, and titanium are 0.09, 0.28, and 0.16 lb per cu., respectively. Magnesium alloys lend themselves to welding and filler are protected by an inert gas. They are relatively easy to cast by most foundry methods, particularly die casting. Nickel –base alloys: Nickel is one of the oldest metals known to man. Currently this metal is almost indispensable in the alloying of steels to confer toughness, uniformity of hardness, and good workability; and as a basic alloy to resist high corrosion and high temperatures Lead-Tin alloys: The principal lead –tin alloys consist of solders and bearing materials. The 70% tin -30% lead solder is used mainly in the joining and coating of metals. The 63% tin-37% lead is a eutectic type solder developed primarily for making electrical joints. Zinc-base alloys: Zinc base alloys predominate as die casting materials. These alloys have high cast ability and favorable mechanical and chemical properties. Zinc base alloys can be cast in the range 750-800  º F, and, therefore, have a low –temperature advantage over other alloys Less common metals and alloys: Titanium and its alloys: Because of their high strength- weight ratio, titanium and its alloys have received a great amount of attention from the aircraft and missiles industries. Molybdenum: This element has long been known for its ability to confer the property of high temperature stability to steels. Zirconium: Zirconium metal has a density of 0.24 lb per cu in. And a melting point of 3355 ºF. The metal has fair tensile strength, depending somewhat upon its method of manufacture. It fabricates similar to titanium, and it’s eminently suited to the resistance to corrosion. List of advantages Non ferrous metal do not corrode (aluminum for example) High thermal conductivity High electrical conductivity Non ferrous metals have relatively high density Nonmagnetic properties Higher melting points Resistance to chemical They are also specified for electrical applications They are comparatively low in electrical conductivity Non ferrous have inherent susceptibility to corrosion in some common environment Non ferrous metals are usually light weight but ferrous metals are heavier Limitation of the material in engineering applications They are not as strong as carbon steel (ferrous metal). Non ferrous metals are typically not used in structural applications. Non ferrous metals are usually more expensive by the pound than are ferrous metals. Low tensile strength but excellent specific strength. They don’t show ductile to brittle transition in low temperature. c) Polymers: Compounds that are formed by the joining of smaller layers, usually repeating, units linked by covalent bonds are called polymer. A polymer is a large molecule consists of repeating structural units connected by covalent bonds. Polymer in popular used as plastic; the term polymer refers to a large category of natural and synthetic materials with a wide spectrum of properties. Natural polymers are those which come from plants and animals have been used for many centuries; these materials include wood, rubber, cotton, wool, leather, and silk. Other polymers such as proteins, enzymes, starches, and cellulose are important in biological and physiological processes in plants and animals. The backbone of a polymer used for the preparation of plastics consists mainly of carbon atoms. Polymer in popular used as plastic, the term actually refers to a large class of natural and synthetic materials with a wide variety of properties Polymers: Polymers are classified into several ways, by how the molecules are synthesized, by their molecular structure, or by their chemical family. Linear polymer Any polymer in which molecules are in the form of spaghetti-like chains. Thermoplastics Linear or branched polymers in which chains of molecules are not interconnected to one another. Thermosetting polymers Polymers that are heavily cross-linked to produce a strong three dimensional network structure. Elastomers These are polymers (thermoplastics or lightly cross-linked thermo sets) that have an elastic deformation > 200%. Polymers are classified into three main categories; Thermoplastics: Branched polymer Any polymer consisting of chains that consist of a main chain and secondary chains that branch off from the main chain. Crystalline is important in polymers since it affects mechanical and optical properties. Tacticity Describes the location in the polymer chain of atoms or atom groups in nonsymmetrical monomers. Liquid-crystalline polymers Exceptionally stiff polymer chains that act as rigid rods, even above their melting point. Elastomers (Rubbers): Geometric isomer: A molecule that has the same composition as, but a structure different from, a second molecule. Diene: A group of monomers that contain two double-covalent bonds. These monomers are often used in producing elastomers. Cross-linking: Attaching chains of polymers together to produce a three-dimensional network polymer. Vulcanization: Cross-linking elastomer chains by introducing sulfur or other chemicals. List of advantages Polymers are ultra durable Flexible doesnt rust slow to degrade They can be molded into virtually any shape conceivable can be custom colored in the production stage Polymers are recyclable quite a good electrical insulator and has a low dielectric constant The biggest advantage for PP is its low cost It also has a flexibility in cold whether with ultraviolet stability can be easily repaired from mechanical damage with simple field tools Limitation of the material in engineering applications In the production stage, polymers are susceptible to contamination The least bit of dirt or cross-contamination w/other polymers, and at best the end product is corrupt, at worst the polymers are rendered useless Any variances in heat and timing in the molding process and, again, the final product will be corrupt or useless. lower melting point flammability Elevated temperatures will make any crystalline more isotropic non bio-degradable easily breakable when polymers incorporated with additives are burnt they emit a lot of poisonous gases into the atmosphere improper disposal leads to environmental pollution undergo oxidation and ozonation easily d) ceramics: These are materials that are produced when two materials are joined together to give a combination of properties that cannot be achieved in the original state. Ceramics can be divided into two classes: advanced and traditional. Advanced ceramics consist of carbides, pure oxides, nitrides, non-silicate glasses and many others; while Traditional ceramics include clay products, silicate glass and cement. A ceramic is an inorganic, non-metallic solid prepared by the action of heat and subsequent cooling. Ceramic materials may have a crystalline or partly crystalline structure, or may be amorphous. Agglomerated materials: Concrete: This is one of the oldest agglomerated composite materials to be used for engineering construction, and consists of a mixture aggregate and sand bonded together by the hydrated silicate the gel formed when the Portland cement â€Å"sets† with water. Ratio of aggregate, sand and cement: A very common mix consists of 4parts aggregate, 2parts sand and 1 part cement powder. The water-cement ratio: The water added to the concrete is used in the hydration of the cement itself, and any water in excess of the amount required for setting reactions has a weakening effect upon the concrete. The nature of the aggregate and sand: The bond between the hydrated cement and the aggregate and sand is improved if the both the aggregate and sand are sharp-cornered rather than rounded. Strong fine-grained igneous rocks like basalt, dolerite, and quantize are commonly used for concrete aggregate, the size of which varies with the size of the job. Mixing and laying: Under-or over-mixing gives a poor concrete, and the method of lying is of the utmost importance. Concrete vibrated into place is always stronger than concrete poured and hand-screwed Curing time: The hardening of cement occurs over a considerable length of time and it is important to prevent the evaporation of moisture .during the initial stages. Concrete is often covered with wet sand or bags for seven days to prevent the evaporation of moisture, and concrete cured under water after taking its initial set achieves its maximum strength. Asphalt paving: This is composite in which rock aggregate is bounded by viscous asphalt: it is used extensively for road surfacing. The material is not as rigid as concrete, this being an advantage for road construction. Cermets: These are agglomerates that consist of combinations of metal and ceramics, the metal acting as the binder. Cermets are made using the techniques of powder metallurgy, the sintering temperature usually being above the melting point of the metal powder. Laminates: Many different types of laminated materials are made of different applications, the mild-steel-stainless combination being a good example of a modern metal-to-metal laminate. Plywood: This is made by bonding together an odd number of sheets of wood veneer so that the grain directions of alternate sheets are perpendicular to each other. Laminated plastic sheet: This is usually made from sheet of paper or cloth and a suitable thermosetting resin. The paper or cloth passes or cloth passes through a tank containing the resin solution, between rollers that squeeze out the excess resin, and then through a drying oven in which excess solvents are removed and the resin is partially cured. Reinforced Materials: It forms the biggest and most important group of composite materials, the purpose of reinforcement always being the improvement of strength properties. Reinforcement may involve the use of a dispersed phase, or strong fiber, thread, or rod Reinforced concrete: This is the most widely used of all construction materials, since it is not only comparatively easy to place into position and finish, but is also maintenance free during its service life. Glass-fiber reinforced plastics: These combine the strength of glass fiber with the shock resistance and formability of a plastic. The usual types of reinforcement are the chopped strand mat and the woven fabric, the latter giving increased strength to the composite. List of advantages They are harder and stiffer than steel more heat and corrosion resistant than metals or polymers less dense than most metals and their alloys plentiful and inexpensive doesn’t conduct electricity Ceramics are used in the manufacture of knives. The blade of the ceramic knife will stay sharp for much longer than that of a steel knife, although it is more brittle and can be snapped by dropping it on a hard surface Ceramic engines are made of lighter materials and do not require a cooling system and hence allow a major weight reduction Ceramics are also more chemically resistant and can be used in wet environments where steel bearings would rust High-tech ceramic is used in watch making for producing watch cases scratch-resistance In very high speed applications, heat from friction during rolling can cause problems for metal bearings; problems which are reduced by the use of ceramics Durability and smooth touch. ceramic materials may be used as bone replacements Limitation of the material in engineering applications The main disadvantage of medical ceramic materials is their fragility The ceramic materials cannot deform under the stress, as can do plastics and metals Ceramics do not perform well with tension or tensional loads. A hard, brittle material that can withstand high temperatures and resist corrosion Ceramics cannot be joined (and repaired) by welding. The other disadvantage is that ceramics are strong in compression, but weak in tension Ceramics dont bend much, and when they break, instead of slowly pulling apart the way metals will, they generally snap they have a tendency to shatter when something hits them hard Q-2 An overview of the engineering properties and behavior of ferrous metals, Non-ferrous metals, polymers composites, and ceramics a) Ferrous metals.

Alloy steels have greater harden ability than plain carbon steels Alloy steel have greater harden ability than plain carbon: The difference between the two is somewhat arbitrary definition. However, most agree that while the steel alloyed with more than eight percent of its weight of other elements besides iron and carbon steel is a strong ally. Low alloy steel is slightly higher. The physical properties of these steels are modified by other factors, making them more hardness, strength, corrosion resistance or hardness compared to carbon steel. For these properties, these alloys are often heat-treated. Carbon steel is steel that does not contain significant amounts of alloying elements other than carbon. There are three major categories of carbon steel. A low-carbon steel, medium carbon and alloy. Alloy steel is a type of steel that many advantages over steel offers. It is much harder and stronger than ordinary carbon steel by. It is used in cars, trucks, cranes, bridges and other structures can handle a large number of strains The difference between the two is defined somewhat arbitrarily.

A type of cutting material is relatively expensive and must be directly casted into the form. Non-ferrous cast alloy tools have largely been replaced by carbide. Wrought alloy: Solid metal that has been bent, hammered, or physically formed into a desired shape. Wrought copper alloys can be utilized in the annealed, cold-worked, stress-relieved, or hardened-by-heat-treatment conditions, depending on composition and end use. Bronzes comprise four main groups: copper-tin-phosphorus alloys (phosphor bronze) copper-tin-lead-phosphorus alloys (leaded phosphor bronze) copper-aluminum alloys (aluminum bronzes) copper-silicon alloys (silicon bronze) Wrought copper-nickel alloys, like the cast alloys, have nickel as the principal alloying element. The wrought copper-nickel-zinc alloys are known as nickel silvers because of their color. c) Polymers: Polymers are classified in various way
