Slavery Abolished - 1431 Words

In 1833, slavery was abolished in the British Empire after years of conflict and the hard work of abolitionists in London. Around the era of slavery more people were for it than against it. Even though there were too less people against it, they were still stronger believers. In this essay I will be discussing the persuasive arguments and events that took place to cause the abolition of slavery in the British Empire by 1833. The three causes were what the Abolitionists did, actions took by the slaves and the economic reasons. The White Campaigners The Abolitionists Parliament passed on the Slavery Abolition Act in 1833. The act gave all slaves in the British Empire their freedom. It was one of the great issues of the 19th century. By 1833†¦show more content†¦By 1800, there were slaves being sold in Britain and being taken against their will to the West Indies, but most black people in Britain were free through their own efforts. Some slaves rebelled as source 3 shows us, quot; slaves on the island of St Dominique set fire the sugar cane,quot; this portrays the image that if they started being more aggressive towards the plantation owners business then they would be scared and try to make a treaty with them. This treaty would have rules like payment must be allowed or they wont work and many other rules and regulations to make it fair on the slaves working extremely hard for 15 hours or more labor. There were other methods in which slaves used against their owners so they would be freed or payed these were, act ill, work less hard, sabotage crops, act stupid also pretend they dont know English even though they have been in that plantation area or 10 years or more; this would create the owner a huge cost in money and they would loose all theyre profit. They would have no choice to either free the slaves or pay them. This second reason links in with the economy problems because the slaves sabotaged and rebelled against the plantation owners fields and crops causing the owners huge costs and reductions from rich to poor. The last reason for the abolition of slavery was that it was no longer making such a profit. From the 1770s onwards the West Indies were becoming lessShow MoreRelatedSlavery Is The Inhuman Act And Should Be Abolished Essay1589 Words   |  7 PagesThroughout history, slavery has always played a vital importance in American History.

The Cultural Revolution A Period Of Loss For China

Katie Zhang Richardson WH-II Research Paper 5 June 2015 The Cultural Revolution was a period of loss for China; 1.5 million lives were lost, but even more lost their property, their dignity, and their culture. The instigator of this period of devastation, Mao Zedong, crippled China (â€Å"Cultural Revolution†). Mao, the most influential man in Chinese history, was able to obtain power through repressive campaigns and his ruthless Red Guard supporters. When Mao Zedong was born in 1893, China was in a terrible state. The Opium War, the Open Door Policy, and the unsuccessful Boxer Revolution left China in widespread devastation. As the Qing Dynasty ended in 1912, new leaders prepared to take power (Gay 16).

There, Mao or ganized a rag-tag army composed of bandits and peasants called the Red Army. The Red Army was ill-equipped yet by using guerilla warfare and Mao’s battle slogans, â€Å"When the enemy advances, we retreat! When the enemy halts and encamps, we trouble them! When the enemy seeks to avoid a battle, we attack! When the enemy retreats, we pursue,† the Red Army was able to gain territory from the KMT from 1930 to 1934 (Gay 36). However, by the end of 1934, the KMT surrounded the Red Army and they were forced to retreat. For a six thousand miles journey from the Jiangxi Province to the Shaanxi Province, the Red Army marched to save themselves from the KMT. This trek was known as the Long March. Out of the estimated one hundred to two hundred thousand soldiers that marched, only seven to eight thousand survived (Gay 39). When the Red Army arrived at their destination at Shaanxi, Japan had taken advantage of the civil war and had invaded and occupied all of Manchuria, a mineral rich land in northern China (Malaspina 57). As Japanese troops moved south, the Red Army temporarily combined forces with the KMT to fight off Japan. Yet even with combined forces, the

In the designed system 10 tons corn flakes per day is produced. After some processes, corn flakes enters the roasting oven at 20% humidity and exits at 4%humidity. The roasting oven can operate at ( ±10 ? C) 225 0C. Toasting oven is designed by considering its length, area and operating temperature. Optimizations are done according to these factors on the cost of the total design. In the design system, rotary drum drier is used. 350 days of the year plant works and production occurs 16 hours in a day. Corn flakes enter the oven at 225 0C . Amount of air is calculated as 0,648 kg dry air/s . Length of the drier is calculated as 2. 27 m. in the result of optimizations done according to proper drying time and dryer diameter. Heat energy needed to raise the inlet temperature of air to 225 0C, is found as 157kw and heat loss is found as 23. 6kw. Through these data, total investment which contains dryer cost and electricity cost is found as 92794. 98TL. Sincerely, group 3 members TABLE OF CONTENT SUMMARY In this design a rotary dryer is designed for drying of corn flakes which have the moisture content 20%. Corn flakes are dried with air 9 % moisture content. The production is done for 16 hours in a day and 10 tons corn flakes are produced per day. In production process, corn flakes are cooked under pressure. After cooking step, big masses are broken to pieces and sent to driers in order to get the moisture level at 20%. After this process, roduct is flaked between large steel cylinders and cooled with internal water flow. Soft flakes are sent to rotary dryers in order to dehydration to 4% final moisture content and toasting. In the toasting oven, flakes are exposed to 225 0C air for 2-3 min. The drier length is calculated as 2. 27 m with the diameter of 0. 082m with the assumption of 4%moisture content inlet air and 9%conten t outlet air. Flow rate of feed is calculated as 0. 206kg/s. Mass flow rate of the inlet air is calculated as 0,648 kg dry air/s. Energy needed for bring the temperature of air to 225 0C is calculated as 157kw and heat loss in the system is 23. kw. By making optimizations total capital investment is calculated as92794. 98TL which includes 84881TL electricity cost and 7913TL dryer cost. Finally by making optimizations, in order to have minimum length and suitable energy for the drier, 215 0C is chosen the best temperature for the inlet air. I. INTRODUCTION Rotary dryers potentially represent the oldest continuous and undoubtedly the most common high volume dryer used in industry, and it has evolved more adaptations of the technology than any other dryer classification. [1] Drying the materials is an important consumption process. It is also one of the important parts in cement production process, and affects the quality and consumption of the grinding machine. Drum dryer is the main equipment of drying materials, it has simple structure, reliable operation, and convenient to manage. However there are some problems which are huge heat loss, low thermal efficiency, high heat consumption, more dust, and difficult to control the moisture out of the machine. It plays a significant role in improving drying technology level and thermal efficiency in drying process, reduce the thermal and production lost. 2] In this design we are asked to design a rotary drier which works 16 hours in a day and produces 10 tones corn flakes per day. Also it is mentioned that, corn flakes enters to drier at 20 %humidity and exits 3-5%humidity. This report is about designing a rotary dryer with its dimensions for considering to get the minimum total cost. Optimizations are done according to inlet temperature of the air to the drier. In the design system heat needed for heating the inlet temperatures and length of the rotary dryer as material cost is thought, and optimization is done by considering minimum total cost for the system. II. PREVIOUS WORK Drying is perhaps the oldest, most common operation of chemical engineering unit operations. Over four hundred types of dryers have been reported in the literature while over one hundred distinct types are commonly available[3] Drying occurs by effecting vaporization of the liquid by providing heat to the wet feedstock. Heat may be supplied by convection (direct dryers), by conduction (contact or indirect dryers), radiation or by microwave. Over 85 percent of industrial dryers are of the convective type with hot air or direct combustion gases as the drying medium. Over 99 percent of the applications involve removal of water. [3] * Rotary Dryer; All rotary dryers have the feed materials passing through a rotating cylinder termed a drum. It is a cylindrical shell usually constructed from steel plates, slightly inclined, typically 0. 3-5 m in diameter, 5-90 m in length and rotating at 1-5 rpm. It is operated in some cases with a negative internal pressure (vacuum) to prevent dust escape. Depending on the arrangement for the contact between the drying gas and the solids, a dryer may be classified as direct or indirect, con-current or counter-current. Noted for their flexibility and heavy construction, rotary dryers are less sensitive to wide fluctuations in throughput and product size. [4] * Pneumatic/Flash Dryer;The pneumatic or ‘flash’ dryer is used with products that dry rapidly owing to the easy removal of free moisture or where any needed diffusion to the surface occurs readily. Drying takes place in a matter of seconds. Wet material is mixed with a stream of heated air (or other gas), which conveys it through a drying duct where high heat and mass transfer rates rapidly dry the product. You read "Designing a Toasting Oven in Order to Produce Corn Flakes" in category "Essay examples" Applications include the drying of filter cakes, crystals, granules, pastes, sludge and slurries; in fact almost any material where a powdered product is required. * Spray Dryers; Spray drying has been one of the most energy-consuming drying processes, yet it remains one that is essential to the production of dairy and food product powders. Basically, spray drying is accomplished by atomizing feed liquid into a drying chamber, where the small droplets are subjected to a stream of hot air and converted to powder particles. As the powder is discharged from the drying chamber, it is passed through a powder/air separator and collected for packaging. Most spray dryers are equipped for primary powder collection at efficiency of about 99. 5%, and most can be supplied with secondary collection equipment if necessary * Fluidised Bed Dryer; Fluid bed dryers are found throughout all industries, from heavy mining through food, fine chemicals and pharmaceuticals. They provide an effective method of drying relatively free flowing particles with a reasonably narrow particle size distribution. In general, fluid bed dryers operate on a through-the-bed flow pattern with the gas passing through the product perpendicular to the direction of travel. The dry product is discharged from the same section. * Hot Air Dryer- Stenter; Fabric drying is usually carried out on either drying cylinders (intermediate drying) or on stenters (final drying). Drying cylinders are basically a series of steam-heated drums over which the fabric passes. It has the drawback of pulling the fabric and effectively reducing its width. For this reason it tends to be used for intermediate drying * Contact Drying- Steam Cylinders/Can; This is the simplest and cheapest mode of drying woven fabrics. It is mainly used for intermediate drying rather than final drying (since there is no means of controlling fabric width) and for pre drying prior to stentering. * Infra red drying; Infrared energy can be generated by electric or gas infrared heaters or emitters. Each energy source has advantages and disadvantages. Typically, gas infrared systems are more expensive to buy because they require safety controls and gas-handling equipment, but they often are less expensive to run because gas usually is cheaper than electricity. Gas infrared is often a good choice for applications that require a lot of energy. Products such as nonwoven and textile webs are examples where gas often is a good choice. [5] * III. DISCUSSION For the designed system a rotary drum dryer is chosen. Rotary drum dryer  is used for drying material with humidity or granularity in the industries of mineral dressing, building material, metallurgy and chemical. It has advantage of reasonable structure, high efficiency, low energy consumption[6]   advantages of drum dryer: | | Suitable for handling liquid or pasty feeds. Product is powdery, flaky form Uniform drying due to uniform application of film. Medium range capacities. Very High thermal efficiency Continuous operation Compact installation Closed construction is possible  [7] By hot air stream, heat for Toasting of the flakes in the drier, or in the oven, is provided instead using flat baking surfaces. Depending on the production type and flow rate, drum dryer satisfies rotating at a constant speed, the slope and the length. The drum is also perforated so that allows the air flow inside. The perforation should not too much large but also prevent the escape of flakes. Also, during the thermal treatment browning, expansion degree, texture, flavour, storage stability is determined. In order to obtain the correct values, the drying temperature and time should be adjusted properly. For the optimization of the system, length of the drier, diameter value, working temperature are affect fixed cost, variable cost and the heat loss from the system is considered. First at all, changing by temperature how affect necessary length is calculated T air in| Z| 210| 2,308504| 215| 2,296091| 220| 2,284367| 225| 2,273274| 230| 2,262764| 235| 2,252792| It is seen that after temperature of the hot air increases, the necessary length of the system decreases . Due to decreasing of necessary length of the system , area decreases also , so fix cost is decreased (Money of dryer + installation) on the other hand according to table 6 T air in| Q system| electric cost| Area| money for cost of dryer + installation| total cost| 210| 146,708| 79222,32709| ,231014| 7949,192995| 87171,52| 215| 150,2011| 81108,57297| 1,224622| 7936,763821| 89045,34| 220| 153,6941| 82994,81886| 1,218584| 7925,023661| 90919,84| 225| 157,1872| 84881,06474| 1,212872| 7913,916768| 92794,98| 230| 160,6802| 86767,31062| 1,20746| 7903,393249| 94670,7| 235| 164,1733| 88653,5565| 1,202325| 7893,408318| 96546,96| TABLE 6 Q loss is increased , by temperature increase so variable cost(electric c ost ) is increased also. owever, due to not big changing in the areas fix cost variable do not change too much by increasing or decreasing the temperature, but Q loss, on the other hand, makes too much difference by increasing or decreasing the temperature and also electrical cost for one kw/h is 0. 15 TL ,the difference of changing one temperature to other one is too big than fix cost. And according to data and tables, the optimum temperature is 2100C due to this reasons do not have a specific curve to us , the result is predicted as the minimum temperature. i. Assumptions * Working time of the plant is assumed as 16 hours Drying time is assumed as 150 seconds (optimum time is given as 2-3 minutes). * Surface temperature of the corn flakes entering the drier is assumed as 25oC(Tfeed=25oC) * Humidity of the air at the inlet and the outlet is assumed as 0. 04 and 0. 09, respectively. * Specific heat of the air is assumed as constant. ( cp,air=1. 02kj/kg*K) * Only the constant drying rate is considered in the calculations since it has a critical moisture of 4. 5-5. 2 %. [4] * The shape of the flakes is assumed as spherical. * Radius of dryer is taken as 0. 082 m The efficiency of the drier is assumed as 85% to realize the calculations. ii. Possible source of errors * The shape of the corn flakes may not be perfect spheres. * Calculations may be done improperly due to the air humidity assumptions. * The corn flakes may be stuck on each other. * IV.

CONCLUSION AND RECOMMENDATIONS To sum up, the aim of this design project is to design a toasting oven for corn flakes to decrease its moisture content from %20 to 3-5 %. For this purpose, by using inlet temperature, humidity of air and inlet temperature and moisture content of corn flakes the system is designed. Moreover, during calculations length and radius of dryer, operating time, operating capacity and heat losses from the system is considered. After doing this calculation, the optimization done by altering the working temperature of the system and dryer radius and by considering heat losses from the system. These alterations affect to the both variable and fixed costs and different fixed and variable cost values are obtained. Different total costs values are obtained by using fixed cost and variable cost values and optimization is done. Finally, it is conculed that the dryer length is 2. 27 m when inlet air temperature is 225 oC. However, optimum length is obtained when the inlet air temperature is 215 oC which is 2. 296 m by considering total cost for the system. As a result, theoretical calculations are integrated with practical approach and feasible system is designed for the problem. As a recommendation, for the drying process of corn flakes other dryer types can be used. Fluidized bed dryer can be used for this process. There are some important advantages of this dyer. As an example, this type of dryer has very high thermal efficiency and low processing temperature can be used for the processing. [8] Moreover, the system should be controlled carefully, because any fluctuations in the temperature or other variables could made adverse effects. Temperature of the inlet air should be censored and color censor should be added to outlet of product to control the quality in a best way. VI.

B) signal reception, signal transduction, and cellular response C) signal reception, nucleus disintegration, and new cell generation. D) the alpha, beta, and gamma stages. E) signal reception, cellular response, and cell division. 4. When a cell releases a signal molecule into the environment and a number of cells in the immediate vicinity respond, this type of signaling is A) typical of hormones. B) autocrine signaling. C) paracrine signaling. D) endocrine signaling. E) synaptic signaling. 5. The yield from putting NADH + H+ through the electron transport chain is ________ ATP and the yield from FADH2 is ________ ATP. A. three, two B. three, four C. four, three D. two, three 6. Fermentation takes place in the ________ of oxygen, a process also known as ________ respiration. A. presence, aerobic B. presence, anaerobic C. absence, aerobic D. absence, anaerobic 7. Pyruvate is the starting compound for ________. A. Alcohol fermentation B. Glycolysis C. Lactic acid fermentation D. All of the answers are correct E. Alcohol fermentation and lactic acid fermentation 8. ________ is the key regulatory enzyme of the glycolytic pathway. A. Hexokinase B. Rubisco C. Phosphofructokinase D. Isomerase 9. What is the role of O2 in electron transport? final electron acceptor 10. What are the three stages of cellular respiration and which one contributes most to ATP yield? Glycolysis, the citric acid cycle and oxidative phosphorylation/electron transport. Oxidative phosphorylation contributes most. 11. Describe the importance of the membrane in electron transport. Provides a ‘substrate’ for the proteins involved; support, positioning relative to each other, etc. Provides a barrier across which protons can be pumped to form a gradient that is later used to form ATP. 12. What pathway is common to both aerobic and anaerobic respiration? Glycolysis 13. What is the key regulatory enzyme of glycolysis and what is the effect of an increased ATP concentration on this enzyme and on respiration in general? The key regulatory enzyme of glycolysis is phosphofructokinase. An increase in ATP concentration means that the cell is not using all the energy that is being produced from the breakdown of glucose. Therefore, phosphofructokinase is shut down to prevent unnecessary breakdown of energy stores (i. e. glucose). Respiration will slow down. 14. What is the primary difference (in general terms) between substrate-level phosphorylation and oxidative phosphorylation? substrate-level phosphorylation involves the transfer of a phosphate group from one molecule to another and oxidative phosphorylation involves the formation of ATP as a result of redox reactions in the electron transport chain. 5.

A type of local regulation in which only the adjacent cells are affected by signal chemicals is called ________ signaling. a. paracrine b. hormone c. autosomal d. neuronal 17. A type of receptor which uses GTP to activate a mobile peripheral protein is ca lled a: ________. e. receptor-tyrosine kinase f. G-protein-linked receptor g. ligand-gated ion channel 18. When a signal molecule binds to ________, the receptor forms a dimer and then has the ability to phosphorylate several different proteins. h. eceptor-tyrosine kinase i. G-protein-linked receptor j. ligand-gated ion channel 19. A(n) ________ is a small, non-protein molecule that functions in a transduction pathway. k. hydrolase l. enzyme m. second messenger 20. ________ is a second messenger that is actively pumped out of the cytosol, which keeps the concentration low. Then, when the second messenger is released, it may have a large effect on several proteins simultaneously. n. cAMP o. Ca2+ p. IP3 q. DAG 21. Different types of cells may respond differently to the same signal molecule because ___________. r. the signal molecule emits different wavelengths of light s. ach type of cell has its own complement of proteins t. the cell may feel threatened by the signal 22. Explain why hormones are not considered local regulators. By definition, hormones act on parts of the body that are distant from the site of production of the hormone. 23. Describe how signal amplification is accomplished in target cells. For each signal molecule, many primary messengers are activated, and for every level of the series of reactions that results, many new reactions are stimulated. 24. What are the three stages of cell signaling? Reception, transduction, response. 25. Describe where receptors for water-soluble and lipid soluble signal molecules are located. For example, receptors for ________ signal molecules are typically on the exterior of the plasma membrane. water-soluble, on the exterior of the plasma membrane; lipid-soluble, inside the cell. 26. What are the two main advantages of using a multistep pathway in the transduction stage of cell signaling? signal amplification and regulation/control 27. Compare kinases and phosphatases in terms of phosphorylation. kinases phosphorylate another molecule; phosphatases dephosphorylate another molecule.

Early Life Essays - Richard Nixon, American Quakers,

Early Life Richard Milhous Nixon grew up in Yorba, California the son of Quakers Frank and Hannah Nixon. During Nixon's childhood in Yorba, the family was always on the edge of poverty. The lemon grove was unfruitful, and there was little money for anything beyond food and clothing for the growing family. The Nixons never ate in a restaurant or took even a brief vacation. Nixon's early life was one of boyish stubbornness. He swam in the dangerous Anaheim Canal in spite of repeated warnings from his father, and he insisted upon standing up to ride in the family wagon, although once a fall gave him a serious head injury. He displayed a competitive streak at an early age and would never turn down a challenge or a dare. He also loved to be read to, and after age five he could read on his own. National Geographic was his favorite magazine. Education Nixon graduated form high school in 1930. He possessed extraordinary intelligence and ambition, but his ambitious nature received a serious setback that year. He graduated first in his class and won his high school's Harvard Club award as "best all-around student." The award was a scholarship to Harvard University in Cambridge, Massachusetts. In addition, he seemed likely to win a scholarship to Yale University in New Haven, Connecticut. Nixon had dreamed for years of going to a famous college in the East, but his dreams were shattered when he had to turn down both opportunities. Because his older brother Harold's long battle with tuberculous had drained the family's funds there was no money to pay for the cost of traveling to the East Coast and living there. Nixon swallowed his disappointment and enrolled at nearby Whittier College. Nixon majored in history, and one of his history professors had a profound influence on his career. This was Dr. Paul Smith, whom Nixon called "the greatest intellectual inspiration of my early years." Smith was a Republican who urged his students to think about the importance of leadership in government. He encouraged them to consider entering public office, and he certainly helped turn Nixon's thoughts in that direction. In 1934 Nixon graduated from Whittier College after four years on the honor roll. He applied for a scholarship to a new law school, at Duke University in Durham, North Carolina, and asked several of his professors to write to Duke, recommending him for a scholarship. Thanks to one convincing letter from the president of Whittier College saying that Richard Nixon would become a great American leader someday, Nixon was given a scholarship to Duke Law School. After his third year at Duke, Nixon graduated from Duke Law School in 1937. Nixon was ranked third in his class of 25 students. Immediately after graduating, he passed the California Bar Exam which every lawyer wishing to practice law in California must pass. Positions held before the Presidency After passing the bar exam, he practiced law in Whittier, California, and briefly served with the Office of Price Administration before enlisting in the U.S. Navy during World War II. In 1947, Nixon won a seat in the U.S. House of Representatives in a campaign noted for his accusation that his Democratic opponent was supported by Communists. As a member of the House Committee on Un-American Activities, he gained fame for his part in the Alger Hiss spy case. He went on to the U.S. Senate in 1951, again after suggesting that his Democratic opponent was tainted by Communist associations. Nixon became Eisenhower's vice-president in 1952 and was unusually visible and active in that role. In 1958, he faced down hostile demonstrations in Peru and Venezuela, and in 1959 he had his famous kitchen debate with Khrushchev at an American exhibit in Moscow. After narrowly losing the presidency to Kennedy in 1960, Nixon lost a bid for governor of California in 1962, a loss which appeared to be the end of his political career. Accomplishments of his Presidency Some of Nixon's most acclaimed achievements came in his quest for world stability. During visits in 1972 to Beijing and Moscow, he reduced tensions with China and the U.S.S.R. His summit meetings with Russian leader Leonid I. Brezhnev produced a treaty to limit strategic nuclear weapons. In January 1973, he announced an

WASHINGTON Surname Origin and Last Name Meaning

WASHINGTON Surname Origin and Last Name Meaning The Washington surname is believed to have originated with the English place name Washington, the name of a parish in Durham, five miles from Gateshead, and also of a parish in Sussex, ten miles from Shoreham. The original bearer of this surname could, therefore, have hailed from either of these places. The Washington place name itself is derived from the Old English personal name wassa, which means hunting, combined with the locative suffix -thn, meaning settlement, homestead. Another possible origin for the place name comes from weis, meaning wash, or the shallow part of a river, plus ing, or a meadow or low ground, and ton, for dun, a hill or town.  Thus the place name Washington could have been used to describe a town located on a wash or creek. Alternate Surname Spellings:  WASHINTON, WASSINGTON, WASSINGETON Surname Origin: English Where the Washington Surname Is Found According to  WorldNames public profiler, the Washington surname is most popular in the United States, especially in the District of Columbia, followed by Louisiana, Mississippi, South Carolina, and Alabama.

Crime on the streets Essay Example | Topics and Well Written Essays - 750 words

Crime on the streets - Essay Example There are cases in which a person coming from a problematic heredity has been developed a sound healthy personality. On the other hand we have stories of persons who were brought up in a malicious environment became good citizens. Consumerism has conquered the current world and the advancement in science and technology has raised the living standards. Poor people always watch the rich ones with surprise and jealousy. The thirst for such higher living standards and the negligence suffering from the society will force them to adopt any kind of activities in order to earn money irrespective of good or bad. Urban areas are more volatile to violence and criminal activities compared to rural areas. Persons living in areas with heavy concentrations of the very poor, experience anomie: a state of normlessness. The poor youths in such areas may not have good jobs and education which prevent them from achieving higher living standards. But their expectations and targets will always exceeds what actually they deserved or capable of achieving which may force them to engage in criminal activities. Rich people normally stay in urban areas with high degree of living standards. The poor around such rich community often come across with such higher living standards which eluded them because of their poverty. Desperations will creep up and the poor, especially the youths who have more frustrations compared to the older people, may start criminal activities like robbery, theft and pick pocketing. But poverty alone cannot be sited as the reasons for criminalization of poor urban youths. A persons poverty may very well shape other life experiences and life choices, but it has very little direct influence on criminal behaviour. For example, we have lot of examples in which even the richest people engaged in violent criminal activities. â€Å"Abused and neglected

Drivers Influencing SMEs in the UK Term Paper Example | Topics and Well Written Essays - 2500 words - 1

Drivers Influencing SMEs in the UK - Term Paper Example To begin with, the UK is a developed country that is considered economically stable and highly competitive in the global market. In fact, in 2008 it was ranked in terms of nominal Gross Domestic Product (GDP) in the European region. In addition, it is the sixth largest economy globally in terms of Purchasing Power Parity (PPP) (Excellis Business Consulting, 2009). The country is a member of some of the most prominent organisations in the world including the European Union (EU), North Atlantic Treaty Organisation (NATO), Organisation for Economic Cooperation and Development (OECD), the United Nations Security Council, World Trade Organisation (WTO) and the G8 (Excellis Business Consulting, 2009). The country’s population was slightly below 50 million according to a census conducted in 2008 and ranked third in the EU (Excellis Business Consulting, 2009). The UK remains one of the proficient players in the global economy after recovering from the economic and political effects of the two world wars. Manufacturing is a key component of the UK economy however, it can be noted that it only accounted for approximately 13 percent of the output in 2003. The industry also contributes nearly half of the exports and ? 150 billion annually (Excellis Business Consulting, 2009). This trend has led to the increased levels of transfer of the UK manufacturing base and foreign ownership. In recent times, UK based companies are no longer the leaders in the manufacturing sector. Nevertheless, the UK still ranked sixth worldwide with regards to Gross Value Added (GVA) and manufacturing output (Excellis Business Consulting, 2009). Most conventional manufacturing companies have evolved into new activities such as silicon design, silicon design, in-flight refueling systems, and Bluetooth technology. Other manufacturers have engaged in the development of state of the art technologies in nanotechnology, information technology, and communication. In 2006, 25 percent of the exports were in the high technology class compared to 22 percent in the US and 15 percent in France (Excellis Business Consulting, 2009. Globalisation has both positive and negative impacts on SMEs. It poses numerous challenges such as increased competition and exposes the economy to pressures in the global economy such as recessions (Beise, 2004). Globalization allows for the free trade and global companies can trade in the UK market resulting in increased competition (Dicken, 2007:5). This affects the viability and competitiveness of SMEs. Owing to the fact that SMEs are in search of uncontested market space, globalization leads to an increase in the number of players in the market and this increases the level of competition faced by the SMEs thereby negatively affecting profitability. Through globalization, the global economy is viewed as one entity hence if there is an economic crisis in one economy it is likely to have a ripple effect on other economies. This means that SMEs are more e xposed to global economic crises owing to the rising trend of globalization (Dicken, 2007:5). These are the negative impacts of globalization on SMEs.

Should the university cancel on-line courses Essay - 1

Should the university cancel on-line courses - Essay Example The results of such studies insinuated that the positive perception regarding online education has continued to grow. Apart from the previously mentioned driving factors, the study also revealed that its growth is facilitated by the increase in the adult population who seek education. It has also grown because most school leaders have endorsed it as an equally competitive option. Above all, the advancement in the information technology concepts has triggered the adoption of online education. This paper focuses on discussing whether universities and colleges should cancel online courses. The initial theory and stand of the argument is that online education provides an alternative that is equally competitive in every aspect compared to the traditional or classroom learning approach. For this reason, higher learning institutions should not cancel online education. One of the most obvious reasons why online courses should not be rescinded is owed to the flexibility and convenience presented by the education system (Ni, 205). The learning system allows individuals who have tight schedules such as working mothers, to access education at their convenient time. Other people who exist in the same category include managers and students who wish to pursue multiple courses at the same time. In this context, such people can access education without interfering with other equally important agendas. On the same context, it helps students to access education without being inconvenienced by longer distances of separation between the location of the institutions and their locations. Secondly, it provides alternatives for students who cannot find their preferred courses in the universities near them without having to relocate to other regions. Studying online is also advantageous because the web is full of different kinds of information that may support students study progress.

Short Answers to Questions on providing nursing care for clients

Short Answers to Questions on providing nursing care for clients Treatment provided to manage pain and alleviate suffering experienced by a person dying. Palliative care is a unique moment in life where emphasis is on the journey not the destiny. In adopting a holistic approach to care practice the nurse can support the essence of the individual by ensuring their comfort and needs are met within an environment conducive to stages of end of life living. (Harris, Nagy Vardaxis 2006, p.1274). b) How does the practice of palliative care differ from acute care for the nursing staff? Although death occurs in both practices, expectations of the client by the nursing staff would be significantly reduced in palliative care as the body is in a progressive degenerative state contrary to the acute setting where increases in body functions indicate recovery and expedite discharge (Harris, Nagy Vardaxis 2006, p.28 p.1274). c) What ethical issues may staff face while working in a palliative setting? Contradictions of core values, defining and segregating personal assumptions and professional development of nursing staff would be continuously challenged in a palliative setting. Politics, global economics and organisational constraints would also impinge on ethical issues faced by staff (Johnstone 2006, pp. 130-134). d) What personal care strategies may nurses need to employ to help them deal with the unique stresses related to working in palliative care? Strategies to reduce stress include regular physical exercise, maintenance of a nutritional eating plan, personal hygiene and routine sleep patterns-albeit shift work is disruptive. Acknowledge self-worth either by indulging in a regular luxury or personal time out. Participate in grieving, team de-briefing and grief counselling. Understanding human foibles and maintaining a sense of humour can improve coping skills required to deal with stress (McMurray 2005, p.101). e) How can reflective practice be of benefit to nurses in the palliative care settings? Observational skills are heightened when consciously aware of environment and subjectivity can increase the ability to improve outcomes by manipulation. Reflection allows for self and procedural evaluation and promotes resilience. Experience in the clinical care setting combines theory with practical knowledge which can increase coping mechanisms required by the nurse to evolve and adapt to perpetual change (Usher Holmes 2006, pp. 100-105). Q 2 a) List three pathophysiological changes that you may observe while caring for a client in the last few weeks or days of life care? Three changes that may be observed in end life care include; Anorexia-loss of appetite, Akinesia-absence of movement and Atrophy-decrease in muscle and body mass (Porth 2005, p.1501). b) How do palliative illnesses such as cancer affect a persons ability to perform ADLs? The presence of disease, retention of chemical therapy, controlled medication all exacerbate chronic fatigue alienating mind from body increasing frustration borne from the inability to perform activities of daily living. At all stages of disease the body is fighting to compensate perpetuating fatigue encouraging systemic changes that cannot be regulated to resonate throughout the system. One example would be the inability to swallow caused by either obstruction or medication affecting respiration and appetite, creating chemical imbalances in the stomach and along the gastrointestinal tract with further complications resulting in the bowel (Tollefson 2005, pp. 908-911) (Mott 2005, pp. 1379-1380.) c) What interventions and or equipment may be used to support palliative clients to perform ADLs? Equipment may include frames, walkers, lifters, trapeze bars, thickeners in fluids, pureed food, prompts with ablutions and routines. Enable continuity in care by providing succinct habits in documentation and communication with all staff members. Continuous assessment to identify pain, symptoms and recovery times following exertion will assist the nurse in educating and supporting client losses and create realistic alternatives to manage ADLs while encouraging client autonomy. (Mott 2005, pp. 1385-1396). d) How do palliative clients hydration and nutritional needs differ from acute clients particularly during end of life care? Nutrition and hydration needs of the palliative client fluctuate as the effects of anxiety, depression and futility of disease progress. Decline in the bodys need and tolerance for nutrition and hydration which eventuates to mouth swabs and ice chips is compounded by continual bed rest, medication and immobility, further disabling the bodys ability to secrete hormones required to regulate and balance homeostasis and avoid organ failure. Generally with acute care clients, the body is capable of compensating single organ failure by intervening with appropriate responses. Interventions by the body include mobilisation of body defences and an increase in metabolism which requires a balance of nutrition and hydration to promote healing (Tollefson 2005, pp. 1245-1252). Q 3 Case Study Mr Klamic a) What would be the benefits of offering a grief counsellor to Mr. Klamic and his family? Particular benefits of offering grief counselling is that it can allow all family members to address unresolved issues of disillusion and resentment associated with loss. A grief counsellor helps the family understand the processes involved by exploring coping mechanisms, strengthening communication skills, and forming allegiances (Griffiths Crookes 2006, pp. 185-189). b) What would be the benefits of discussing the spiritual and cultural aspects of Mr. Klamics care with Mr. Klamic and his family. Recognition and understanding of specific cultural needs by the nurse will encourage a therapeutic relationship with the client and his family which will facilitate in appropriate care for Mr. Klamic. Promoting inclusion can empower the family to actively participate in care. An example of benefits regarding discussing spiritual needs would be rituals associated with religion as in the administration of Holy Communion and Last Rites (Omeri 2006, pp. 277-280). c) Discuss the grieving process and how it might differ for each of the parties involved, Mr. Klamic, his wife and children. Experience associated with the transition of dying and death is unique and the impact on the surviving family members needs to be acknowledged and addressed. Although Mr Klamics children no longer live at home, the family structure is fractured, dynamics within the family will shift, behavioural changes may occur as perceptions of role in life, become displaced (Mooney 2005, pp. 559-568). d) What significant others or community services could the nurse access for support in the grieving process for Mr. Klamic and his family. Community support services could include, a senior member of the families religious affiliation which would offer pastoral care, Polish associations also offer support with members volunteering their time to friendship visits, respite for family members, Centrelink financial support, Family Services can advise on government assisted funeral schemes, Domicillary help with house, garden and shopping (SA Community Connecting Up Australia 2009, website). e) Why is it important to consider language barriers when information needs to be discussed with a client and their family? Client confidentiality requires medically trained health care translators be appointed when there is a language barrier. Informed consent relies on the understanding of medical information received by the client and their family. Other obstacles that need to be considered with language barriers are loved ones protecting client or denial by client, cultural and religious beliefs, personal and or vested interests by other parties (Dowd, Eckermann Jeffs 2005, pp. 131-137). f) How does pain management in the palliative setting differ from in the acute setting? The goal in palliative care is to comfort and alleviate whereas the focus in acute care is on rehabilitation albeit pain management is ultimately directed by the opinion of the Doctors will. Managing pain with the palliative client requires administration prior, to prevent increases in suffering. Timing of administration when moderated appropriately may reduce dosage required for continual pain control. Generally in acute care initial aggressive pain management is required to stimulate the body, inducing healing processes. Increased homeostasis enables mobility of the body which is beneficial in reducing pain management as the clients body avails to strategies implemented (Tollefson 2005, pp. 1188-1189). g) Other than Opioid use what other strategies may be employed to manage Mr. Klamics pain? All forms of diversional therapy warrant investigation and use of if client is agreeable. Simple strategies of holding a hand, giving a gentle hug, listening, participation in a chat or debate of interest to client, encourage journaling-written or taped, arouse interest in unexplored possibilities. Initiate changes to environment so the client can absorb and enjoy the seasons or an excursion outside in the elements. Massage, aroma, visualisation and music therapy, are alternatives that may be offered to Mr. Klamic to increase his comfort. Guidelines for implementing therapies will probably vary between organisations, prior reference to policies and procedure is recommended (Taylor 2005, pp. 896-900). h) Other than patient statements, what are some of the observations and assessment nurses may use to gauge a patients pain level? Regular assessment of vital signs, deep sadness watery eyes, pallor of the skin, grinding of teeth, flinching and clenching of extremities, irregularities in breathing , inability to find comfort or solace and foetal curling. Listening to and enquiring with family members of noticeable pain. Reduce external irritants and monitor signs on skin; pressure areas, pallor, cyanosis, jaundice, heat and beads of sweat. Reference to medication, pain (Wong Baker) and behavioural charts and levels of participation in activities of daily living may help to gauge clients pain levels (Tollefson 2005, pp. 1183-1198). i) What are the Enrolled nurses responsibilities when caring for a patient with a morphine infusion? Responsibilities include ensuring machine is functioning and calibrated in accordance to pharmacy order and that pain is being controlled and frequently reassessed. Cannulation tube should be free of kinks and the area surrounding the site of insertion is devoid of redness, heat, swelling and pain. Co-signing record of use of a schedule 8 drug on register and reporting variants, adverse reactions and side effects to the Registered Nurse while implementing the five rights of medication are mandatory of the Enrolled nurse working within their scope of practice (Tollefson 2005, p.1210) (Davis, 2005, pp. 874-881) (ANMC, 2007 p.2). Q 4 a) How does Mr Klamics diagnosis affect his ability to be an organ donor? Although Mr. Klamics diagnosis impedes his ability to donate organs and tissue to a living recipient, it may be possible for him to donate himself in entirety to science. Criteria for scientific donation would be assessed on an individual basis by the receiving school of medicine and would require prior contact between Mr. Klamic and or his power of attorney and the particular institution. (The University of Adelaide School of Medical Sciences 2011, website) (Australasian Transplant Co-ordinators Association Incorporated 2006, website). b) When may an autopsy be required in the palliative setting? Who carries out the autopsy, who gives permission for the autopsy?

Brontës Depiction of Women in Jane Eyre :: essays research papers

In Jane Eyre, Charlotte Brontà « uses the female characters to convey her views on Victorian conventions of womanhood. She does this initially by using first-person narrative to help us see the characters in their true form. In this essay I'm going to explain how Brontà « uses the character Jane as porthole for her own views and beliefs. During the period Jane Eyre was set, the 1840's, it was conventional that women were inferior to men and were not entitled to their own opinions or freedom of mind. Brontà « uses Blanche Ingram as an example of a typical woman of the time and the consequences of being so are shown throughout. Brontà « argues this view in her preface that ?conventionality is not morality,? this means that what society may think is widely accepted and respectable, is not necessarily what is right, and she creates Jane Eyre as an example of a woman who believes just this but who has, in the end, become more successful than Blanche. Women in the 19th Century were expected to be beautiful and accomplished or they were nothing. Their decisions were made for them and their work was in the home. Charlotte Brontà « thought this immoral and believed that women should be admired for who they are, not what they look like. To highlight this point she uses the character Blanche Ingram, a young lady ?moulded like a Dian?. When reading of Blanche, we are not presented with a complimentary description, for although many other people may describe her as a beautiful, young and accomplished woman, we hear her description from the voice of Jane, who evidently tends to analyse people with a much deeper meaning than just their appearance, and although Jane does admit that Blanche is young and beautiful, she also describes her to be self-centred and inconsiderate towards others - including Mr. Rochester - to who she appears to show no emotion. This is noticeably illustrated when Jane has been observing Blanche and notes that ?her laugh was satirical and so was the habitual expression of her arched and haughty lip?. The choice of the word ?habitual? shows us that this sort of action is typical of her and that she often acts haughty and satirical. The reader immediately feels contempt for Blanche after this observation, as it portrays her to be arrogant and pretentious, especially as it was an action made towards Adele, who is a described to be a sweet young girl who Jane is fond of.
