From an economic perspective, why is Microsoft to successful Essay

From an economic perspective, why is Microsoft to successful - Essay Example Almost every computer is loaded with Microsoft operating system, without which a computer cannot function, or games. In the initial years, the company focused on creating computer language, but most of the financial success came after it embarked on producing operating systems. Today, Microsoft is one of the most popular and financially successful software companies in the world. Its products have penetrated into every household with a PC because of its easy-to-use and ground-breaking software. This paper explores the success story of Microsoft from the economic perspective. Like any other world famous companies, Microsoft is not without criticisms. It has often been criticized for its alleged bullying tactics rather than earning success through innovation. However, according to Harvard Business School professors Marco Iansiti and Alan MacCormack, the company’s success can be attributed to its capability to predict future technological developments and make maximum efficient use of the major software technologies. One remarkable fact is that Microsoft has seen huge financial successes during phases of technological revolutions because of its ability to adapt to changes. Usually, during such vulnerable phases many large businesses collapse for failing to deliver. Although it has been criticized that Microsoft Corporation’s success is largely due to its monopoly position in the global market which the company has taken full advantage of, Iansiti and MacCormack have a different perspective. They have asserted that â€Å"Microsoft wins throug h effective management of its intellectual property and an ability to spot and react to important trends before they take hold† (Silverthorne, 2002). From the early days of writing simple programming language for computers the company progressed to making operating systems based on the DOS system. In subsequent years, Microsoft grew to become Windows XP.

Burma Religion (Burma) Essay Example for Free

Burma Religion (Burma) Essay Since the Myanmar ancient times, there has been full freedom of worship for followers of Burma religions in Myanmar. So many different religions can be practiced in Myanmar. Buddhism is practiced by almost 90 percent of Myanmar religion Burmas population, with the Myanmar Theravada Buddhism School being the most prevalent. It has a firm hold in Myanmars culture along with an observance of animism, or the worship of ancestors (nat). In Myanmar culture, there are many Myanmar festivals and celebrations held that correlate with nat. Nat also has influence on the practice of Myanmar traditional medicine in Myanmar religion Burma. There are other religions in Myanmar, but they are not as widespread as Buddhism and animism. Some of the beliefs found include Christianity (Baptists) in Myanmar hill areas and Muslims. Christianity is practiced by 5.5 percent of Burmese Myanmar, Islam by 3.8 percent Hinduism by 0.5 percent and Animism by 0.2 percent before respectively in Myanmar. Myanmar is a predominantly Theravada Buddhist country. Buddhism reached Myanmar around the beginning of the Christian era, mingling with Hinduism (also imported from India) and indigenous animism in Myanmar. The Pyu and Mon kingdoms of the first millennium were Buddhist, but the early Burmese Myanmar peoples were animists. According to Myanmar religion Burma traditional history, Myanmar King Anawrahta of Bagan adopted Buddhism in 1056 and went to war with the Mon kingdom of Thaton in the south of Myanmar country in order to obtain the Buddhist Canon and learned Myanmar monks in Myanmar religion history. The religious Myanmar tradition created at this time, and which continues to the present day in Myanmar, is a syncretalist mix of what might be termed pure Buddhism (of the Sri Lankan or Theravada school) with deep-rooted elements of the original animism or nat-worship and even strands of Hinduism and the Mahayana tradition of northern India. Islam reached Myanmar at approximately the same time, but never gained a foothold outside the geographically isolated seaboard running from modern Bangladesh southwards to the delta of the Ayeyarwady (modern Rakhine, known previously to the British as Arakan, and an independent kingdom until the eighteenth century) Myanmar. The colonial period saw a huge influx of Muslim (and Hindu) Indians into Yangon and other Myanmar  cities, and the majority of Yangons many mosques and temples owe their origins to these immigrants. Christianity was brought to Myanmar by European missionaries in the 19th century. It made little if any headway among Myanmar Buddhists, but has been widely adopted by non-Buddhists such as the Karen and Kachin in Myanmar. The Chinese contribution to Myanmars religious mix has been slight, but several traditional Myanmar Chinese temples were established in Yangon and other Myanmar large cities in the nineteenth century when large-scale Chinese migration was encouraged by the British. Since approximately 1990 this migration has resumed in huge numbers, but the modern Chinese immigrants seem to have little interest in Myanmar religion Burma. Some more isolated indigenous peoples in the more inaccessible parts of Myanmar country still follow traditional animism. The Roman Catholic Church, Myanmar Baptist Convention and the Assemblies of God of Myanmar are the largest Christian denominations in Myanmar. There are no totally reliable demographic statistics form Myanmar, but the following is one estimate of the religious composition of Myanmar country: Buddhists: 87% Animists: 5% Christians: 4.5% Muslims: 4% Hindus: 1.5% Burma Arts Jamie Therese Jainar The culture of Myanmar has been heavily influenced by Buddhism. More recently, British imperialism has influenced aspects of Burmese culture, such as language and education. More recently, British imperialism has influenced aspects of Burmese culture, such as language and education. Its neighbors, particularly India, China, and Thailand, have made major contributions to Myanmar culture. In more  recent times, British colonial rule and westernisation have influenced aspects of Burmese culture, including language and education. Historically, Burmese art and literature was based on Buddhist or Hindu cosmology and myths. In addition to the traditional arts are silk weaving, pottery, tapestry making, gemstone engraving, and gold leaf making. Temple architecture is typically of brick and stucco, and pagodas are often covered with layers of gold leaf while monasteries tend to be built of wood. Although court culture has been extinguished, popular street-level culture is vibrant and thriving. Drama is the mainstay of this culture, and just about any celebration is a good excuse for a pwe (show). Performances may recount Buddhist legends, or be more light-hearted entertainments involving slapstick comedy, dance, ensemble singing or giant puppets. Myanmar music is an integral part of a pwe; it originates from Thai and emphasizes rhythm and melody. Instruments are predominantly percussive and include drums, boat-shaped harps, gongs and bamboo flutes. The toys of Myanmar are not only for the children but also famous in the world, known as the Marionettes (or) Puppets of Myanmar. It’s a combination of Myanmar Art and Culture, together to show the inner expressions of the Myanmar people. A. The Prehistoric Period c. 1100 BC to 200 BC The Pre historic Period in Burma is known from a limited number of excavations that were carried out in selected rock shelters, caves and other sites along the middle course of the Irrawaddy River. Since Burma even today is sparsely populated, it would not be surprising to find that early cultures in Burma developed in isolation. However, the artifacts uncovered in these digs resemble those in other parts of Southeast Asia indicating that there was meaningful contact over wide areas at a very early date, and the arts in Burma were not isolated even at this early time. This pattern of intra-area contact continued into the later historical periods. Since there are no written records for this early period, we know little about religious practice. However, since the artifacts that have been discovered conform to those used in small-scale societies for animist rituals, it might be presupposed that these early societies practiced a type of Animism. Therefore, Animism, and artifacts associated with its practice, will be discussed as a bridge between this most remote period and contemporary  animist art forms. B. The Pre-Pagan Period Mon and Pyu Urbanism c. 2nd BC – 8 AD During the Pre-Pagan Period there is ample evidence that the lowland peoples in Burma adopted ideas from India as indicated by a few standing structures, numerous excavated foundations, and a wide array of artifacts. These materials were produced for worship in Animism and Hinduism as well as Mahayanna and Theravada Buddhism. The first cities appear throughout central Burma and were directly dependent on extensive irrigation systems. Thus begins the parmountcy of the central region of Burma that continues until the present. The cities occur in well-planned forms that are a combination of indigenous and Indian concepts. Within these cities, the first buildings in non-perishable materials were constructed. These brick and mortar buildings were all used for religious purposes whereas secular buildings, even palaces, continued to be made of perishable materials until the modern era. This dichotomy between the type of material used for construction and the use of the building generally continued through all later developmental periods. Also, at this time, a particular interest develops for two types of religious structures – the Buddhist stupa and the Buddhist temple. Brick foundations of what were most probably the first monasteries are dated to this period. Although the number of images from the Pre-Pagan Period is limited, the diversity of styles and subject matter is generally broader than in later periods. The Mon and Pyu languages are written using alphabets and concepts adopted from India. A Burmese calendar was later created that begins with the fall of the Pyu dynasty in 836 AD. C. The Pagan Period 11th to 13th centuries Classic forms emerged during the Pagan Period for many aspects of Burmese culture, including the economic, political, religious, social, and artistic. These forms were the models used by later Burmese dynasties to create new but related forms, often through slightly modifing their content. Classic architectural forms emerged as embodied in the Shwezigon Stupa and the Ananda Temple that were repeatedly copied by later donors. The styles of sculpture from the Pagan Period were also periodically revived. Theravada Buddhism became the preferred faith and thereafter remained the predominant Burmese religion. The first examples of figurative painting occur on temple walls and employ the Pala style of India and Nepal. Although Pagan ceased  to be the political capital of Burma in the 13th century, the city continued to be a respected religious center and many later monarchs returned to Pagan to endow new foundations or refurbish old ones. D. The Post Pagan Period -14th to 20th centuries After the decline of Pagan, Burma fragmented into a number of small kingdoms that looked back to Pagan for validation and for artistic inspiration. None of these kingdoms rivaled the earlier period in art and architectural accomplishments and all can be seen as â€Å"Pagan writ small†. Pagan buildings were proudly copied, but often with significant modifications. The stupa became the most favored religious building and temples were rarely built. Wooden monasteries constructed on a raised wooden platform largely replaced the brick and stucco monasteries of Pagan. A number of Burmese styles arose, particularly in sculpture, as a result of fewer contacts with India due to the Muslim invasions there and the Muslim destruction of Buddhist religious sites. Burmese styles of painting develop and in the nineteenth century borrow pictorial devices from the West. The Mandalay Style that arose during the latter half of the Post Pagan Period became dominant in central Burma and has continued until the present as the preferred style in Burmese art.

Neurofibromatosis Case Report

Neurofibromatosis Case Report Abstract Neurofibromatosis, though not discussed in depth, is not at all a clinical rarity. The condition has been reported in all races and does not exhibit specific clinical manifestations and features for occurrence. The hereditary nature has been recognized for long, though the depth of mutations is still a long way in short of understanding. It has got a chance occurrence of 50% mutation rate. It occurs with a frequency of 1 case in approximately 3000 births. Malignant transformation has been reported in a few cases, which underlines the importance of in depth analysis of this condition. Introduction Neurofibromatosis is one of the most common hereditary neurocutaneous disorders with an incidence of 1:3000. It is autosomal dominant and shows no race or sex predilection.1 30 to 50% are de-novo cases occurring due to spontaneous mutations.2The condition first documented in 1882 by the German pathologist Frederich Von Recklinghausen presents with protean clinical manifestations.3This case is reported due to the severe facial hemi hypertrophy associated with neurofibromatosis. Case Report A 12 year old female patient presented with swelling of left side of face since infancy. Swelling was first noted at one year of age after which it increased steadily and reached the present size. Speech was slurred. No family history of such a condition was observed. On extra oral examination severe hemi hypertrophy of the maxilla was noted with subsequent disfigurement of the face on account of deviation of the nose and mouth to the right (Fig 1). There was a soft painless mass on the left forehead measuring four centimeters in length and two centimeters in breadth. There was overgrowth of coarse, stiff hair on the mass. The skin showed patchy pigmentation. Left eye is pushed downwards and remained closed due to the pressure exerted by the mass (Fig 23). On palpation the mass was soft to firm with diffuse borders. No fixity to underlying tissue was noted. There was no associated regional lymphadenopathy. Cafà © au lait spots (CALS) of size one to two centimeters and blue black in color were distributed over the trunk and palms of hands (Fig 4). There was a large CALS of size 10 X 15 centimeters in the back of trunk which was irregular with diffuse borders (Fig 5). Intraoral examination showed a firm mass extending from right maxillary lateral incisor to left maxillary first premolar. The mass measured 3 X 2 centimeters in size and was firm and non – tender on palpation. Maxillary left central incisor was found embedded and the lateral incisor and canine were partially exposed. CALS were noted on the mass. Nodular masses were seen on the palate adjacent to right maxillary premolars, on the mass adjacent to right central incisor and on the left upper lip. There was hemi hypertrophy of the tongue and spacing of teeth on the left side resulting in malocclusion (Fig 6). CT scan shows the lesion extended well in to the brain- cerebrum, frontal sinus, and eye, nasal and maxillary sinus (Fig 7). Preliminary hematological investigations including serum calcium and alkaline phosphatase were carried out and values were found within normal limits. Incisional biopsy was performed from the anterior palate. Histopathological examination of H E stained sections showed cells with elongated, bent nuclei separated by abundant, fine and sinuous collagen fibers. There is presence of nerve bundles, mild vascularity and areas of hemorrhage. Overlying epithelium is orthokeratinized stratified squamous epithelium of normal thickness (Fig 89). Diagnosis of neurofibroma was made. Patient was referred to the department of oral surgery for further treatment. Discussion Present knowledge shows that neurofibromatosis consists of at least two diseases which show distinct clinical and genetic features, the peripheral form or neurofibromatosis 1 (NF1) and the central form or neurofibromatosis 2 (NF2). The more common one is the NF1. 4 This is autosomal dominant and 50% of cases are new mutations, 80% of which are of paternal origin. The NF1 gene, one of the largest in the human genome is a tumor suppressor gene located in the pericentromeric region of chromosome 17. It encodes the neurofibromin protein which consists of 2800 amino acids. Due to the large size of the gene and numerous mutations that may occur genetic testing is not a viable option in diagnosis. A protein truncation assay is used to detect stop mutations but this confirms the disease only in two thirds of cases and cannot predict the severity. 5,6 Diagnosis is confirmed if two or more of the diagnostic criteria are present. (Table 1) Hence clinical findings are imperative. Accurate correlations between the genotype and phenotype have not been possible because of the large size of the gene. Still it has been found that the severity of the condition increases with complete gene deletions with occurrence of large numbers of neurofibromas and a significantly higher lifetime risk for malignant peripheral nerve sheath tumors. Familial spinal neurofibromatosis corresponds with mutations at the 3’ end of the gene. Somatic mosaicism may account for the segmental forms of neurofibromatosis.5 The clinical manifestations are first seen in childhood as small macules resembling freckles which slowly increase in size and deepen in color. Microscopically melanin pigment is seen in macromelanosomes. The number of cafà © au lait spots indicates the severity of the disease. In mild forms with fewer spots the neurofibromas occur late in life and may also be restricted to one part of the body. Secondary symptoms may arise due to occurrence of neurofibromas. An abrupt increase in size may indicate malignancy or may be due to pregnancy or onset of puberty.7The central nervous system may be affected with neurofibromas example the optic nerve glioma.8 The skeleton may be affected due to primary defects and also pressure effect from the tumors. Cystic lesions are noted within the bones histologically resembling non-ossifying fibroma.9 Renovascular hypertension occurs due to vascular stenosis. The varied symptoms of neurofibroma include growth disorders, abnormal sexual development and lung abnormalities. Certain forms of neurofibroma shows atypical or incomplete features compared to the classic form. These variants are segmental neurofibroma, gastrointestinal neurofibroma, familial spinal neurofibroma and familial cafà © au lait spots.8 Neurofibroma is a disease with diverse characteristics. Early diagnosis aids in proper monitoring of patient. Genetic counseling is also required in familial cases. Frequent reviews are needed as there is possibility of development of malignant peripheral nerve sheath tumor (MPNST) in a subset of NF1. Proper histologic evaluation is essential as it is difficult to differentiate a neurofibroma with atypical histologic features from a low grade MPNST. Germ-line mutations in genes encoding RAS-ERK signaling pathway components cause a set of related, autosomal dominant developmental disorders, termed â€Å"RASopathies† , which include Noonan syndrome . Noonan syndrome with multiple lentigenes (NS-ML; formerly known as LEOPARD syndrome), cardio-facio-cutaneous syndrome (CFCS), Costello syndrome (CS), and neurofibromatosis type 1 (NF-1). RASopathy patients typically display short stature, facial dysmorphia, cardiac defects, developmental delay, and other variably penetrant features. 10 Conclusion Neurofibormatosis and concomitant symptoms are always associated with numerous manifestations. The condition including von Recklinghausen disease has to be understood in depth for proper diagnostic criteria and treatment protocols. Though, significant steps has been taken for analyzing the molecular pathway and genetic mutations involving the conditions, the finer details are still out of light as far as molecular origin and pathway is concerned. An extensive discussion and deliberation is needed in this regard so that debility and mortality rate

Control Of Sulphur Dioxide Environmental Sciences Essay

Control Of Sulphur Dioxide Environmental Sciences Essay SO2 is an kind of industry air pollution mostly from oil and coal consumption , industry activities and traffics.According to research of EAP(U.S. Environmental Protection Agency) more than 100 million tons sulphur dioxide is discharged into the atmosphere every year all over the world.In the nature,most of the sulphur emissions are in the H2S(hydrogen sulphide),CS2(carbon disulphide),COS(carbonyl sulphide) and some organic compouds.Through burning,these organics which contain sulphur element discharge the sulphur dioxide to the atmosphere,which is able to lead serious environmental problem and harm humans health.SO2 pollution may cause plants dead in a extremely high speed,and is dissolved easily into the wind,which may cause the acid rain that may distroy the outdoor buildings.The most importantly,high concentrated SO2 in the atmosphere is able to kill people or cause serious ills including bronchitis, emphysema and oculoglandular conjunctivitis.Moreover,the sulfuric acid,is a seco ndary pollutant.When sulphur dioxide is involved in additional chemical reactions,it can react with oxygen and water to sulfuric acid which is the constituent of acid rain.(NATHANSON,J.(1986)) Generally,to solve the serious environmental problem,there are two research torwards in removing sulphur dioxide:pretreatment and afterwards absorbing. No matter what methods people use were all included in such two research directions. Pretreatment means separate the sulfur element from the coal mineral before it was burned. Because the main organises of sulfur element in coal are FeS2 and organic sulfur, generally, in industry people often use independent ways to do separation. For the inorganic sulfur including FeS2, the most traditional way is gravitational segregation which means separate the ore containing sulfur element from the coal with the differences in density. Such method is extremely financial and technical simple, however its effects sometimes are limited. Because of the differentia of the coal ore all over the world, the strainaway rate of the sulfur element is highly different. In some area the gravitational segregation can remove approximately 90% of the sulfur element in coal ore, while in some certain coal mines of 40% of the total sulfur content can be wiped off. For the organic sulfur element, it seems that there is not a efffective pretreatment approach to solve it. What people can do is just absorb the SO2 from burning organic sulfocompound. Unfortunately, because of the complicated organization of organic matter, generally, the sulfur contained in the coal ore would be burned in to a series of sulfocompounds including H2S,CS2,SO,SO2 instead of only SO2.So before people assimilate the SO2, people have to transform these compounds into SO2 first. Nowdays the most common way is fluidized bed. Fludized bed is a kind of organization for gasification of coal which is created by Fritz Winkler of Germany on December 16, 1921. Since the early 1960s, Douglas Elliott put forward that the coal should be burned instead of gasifying coal in a bubbling fluidized bed, because the it can generate steam by immersing boiler tubes. In 1982, the first CFB boiler which can burn low-grade coal was built in the Vereingte Aluminum Werke at Luenen, Germany in 1982 which is designed exclusively for the supply of steam and heat. The general gas-solid fluidizetion has 5 major application: Energy conversion, Petro-chemical processing, Mineral processing, Chemical and pharmaceutical and Physical processing, and the basic one is energy conversion. FIGURE 1.2 Schematic of a high temperature fluidized bed gasifier In general coal would be fed into bubbling fludized bed at 950 degree. Steam would be fed into the base of the fluidized bed through a sparge pipe-type of distributor. Then the coal would leave the hot solids in the bed and the cleaned and used gasification products leave the bed from the top. In this process limestone (CaCO3) and dolomite (CaCO3Â ·MgCO3) would be mixed with the coal ores to abstract the SO2 from the burning.The chemical equation is as follow: (1.1) After the fluidized bed step, there is still approximately 20% SO2 left in the offgas. To solve this SO2, people need some technologies including Calcium-Based Reactions and Sodium-Based Reactions, which were called afterburning absorbing. Until now, there is not a cheap and effective approach.The effective methods usually are expensive and lay a heavy burdon on finance,at the same time ,the cheap ones disable to remove the sulphur dioxide satisfactorily. The major information of this paper includes the benefits and defects of the traditional ways controlling the SO2, the rational of the new aspect: magnetic method, the problems may meet and the solutions of this approach..The ultimate purpose of the assignment is to point out a solution both financial and efficient.All the experiments and theories mentioned in this essay are based on theories and logical deductions. Analysis Advantages Nowdays in technology aspect people are able to control the SO2 letting effectively, after all the steps the SO2 discharged into the atmosphere is less then 1%. Materials of these technologies are all hackneved,. Moreover, some certain technologies can produce a series of cost efficient second products such as vitrol and compound fertilizers. Pretreatment is best method to control the sulfur dioxide, personally. Not only because the FeS2 can be separated from the coal ore easily, but also FeS2 can be another useful materials in industry. Because of the characters of coal mines, the associate ore of coal is FeS2 generally. As a result the FeS2 ore occupies a big part of coal mines in anywhere of the world, and the FeS2 ore is the most common material of puddling. So the pretreatment is a both efficient and financial approach. Fluidized bed is the second steps of the whole sulfur dioxide, the absobents of fluidized bed are very cheap and common. So this technology resently is used widly in the countries which are occupying a roomy area such as China and American as a normal skill. And such technology is extraordinary suit for the large-scale factories. Afterburning absorbing is the most efficient way to control the sulfur dioxide discharging regardless of the concentration. The ultimate consistence of SO2 in off gas which is disposed by the afterburning absorbing usually is less than 5%. In summary, the technologys resent used in the SO2 control are highly mature, however there are still some disadvantages can not be ignored. Disadvantages Although pretreatment is the most efficient and financial method to control the sulfur dioxide, it has the deadliest defect: the restriction of area. Because of the difference of the organization of coal ore in different area, such technology disables to be spreaded. For the fluidized bed the problems are secondary products and the processing ratio.When the chalks go into the boiler the active principle, CaCO3 would be resolve into CaO and CO2. The burned CO2 would sepatate out and enlarge the interspace on the CaO to form the lacunose CaO which can response with the SO2 easily. However it is impossible to make all of the CaO be the CaSO4, because the sulphating would make the interspace fullfilled by CaSO4. As a result the most chalks would not response with the SO2 and a great deal of chalks are wasted. Moreover, the secondary products are the mixture of CaSO4, CaO and CaCO3, so that the only way to manage them is dumping which may cause the salinized land. Afterburning absorbing is an efficient approach including wet limestone, wet soda ash/caustic lime spray dryer, circulating lime reactor and sodium bicarbonate/trona injection to control the SO2,however, it also has irrefusable disadvantages: the finance. After the advanced two step there is a lot of SO2 in the offgas, most of which is CO2, so that afterburning absorbing usually is extremely expensive. Moreover such technology has a great deal of problems such as the corrosion on equipments, pipeline blocking and the lack of material use ratio. Discussion Rationale Personally, the basic method to control the sulfur dioxide from the coal, is to separate the sulfur element from the coal ore before burning. In other words, to forbide the shaping of sulfur dioxide is the best way to control it .This kind of ideas is not impossible. If we can make most of the sulfur element separated from the coal before burned into sulfur dioxide, we do not need the afterburn aborbing. Personally people should use another aspect to think about the coal burning. The coal ore is consist of FeS2, ash content and organic organizations. After the pretreatment, almost all of the FeS2 would be remove out of the coal ore, so most of the substance left is organics and ash content. In the fluidized bed, the coal would be transfor into gas, the majority of which is CO2 and sulfide gas. Fortunately the CO2 molecule organizationis nonpolar, and the most of sulfide gas is polar molecule, such as SO2. As we know gaseous phase and solid phase do not have the material difference, nowdays the magnetic force is used widely in the solid waste control. So it is possible that use the magnetic force in separating two kinds of gas which have differences in magnetism. Problems may meet and solution The biggest problem people may meet is the differences between CO2 and sulfur dioxide are too small. This kind of force is only a little bigger than VDW(Van der Waals force), it is impossible to separate all of the CO2 and sulfide gas completely. The method to solve this problem actually is very easy, which is magnify the differences of force suffered. As we know, at the same temperature and pession, the density of SO2 is bigger than that of CO2, that means the climbing velocity of CO2 is bigger than SO2. All the factories need chimneys which are used to let the off gas to upper atmosphere to forbid the impact on daily life. If we add a magnetic field at the bottom of the chimney, it is sure that CO2 would climb up much faster than SO2. That means we can magnify the differences of suffered force between SO2 and CO2. The second problem of this opinion is how to gather the SO2. In my way, it is still to use the magnetic force. The chimney in my plan is not simple one, it should the a concentric tube. There would be a lot of interspace all over the inside tube, which is used to separate the SO2 from the off gas. In the whole chimney, there would be a magnetic field, so that SO2 in the off gas would suffer the magnetic force which is able to make the SO2 run over the inside tube. The outside tube is obfurage, so that SO2 would not be discharged into the atmosphere. The last problem is finance. It seems that the technologies and skills used nowdays play a better role in financial problems than the method mentioned above due to the high cost of basic built and daily power consumption. Although I can not submit the compellent datas about the basic built and daily consumption, I strongly believe that it performs better on the finance than the technologies and skills used now. Most skills of afterburning absorb would consume 15% electronic of the total vield for power plant. That means only 85% power is useful. On the other hand the power consumed in establishing magnetic field is obviously much less. All the power plants in the world would have chimneys, so the basic building cost would not be unacceptable. Furthurmore the secondary product: sulfur dioxide is the resource of manufacturing vitriol. In my opinion, the consumption in power even would be less than the money earned from the secondary product. Advantages and disadvantages In comparison of any other technologies and skills, the ultimate advantage of magnetic force is no secondary pollution. No matter what kind of skills used now have the problem of secondary pollution, such as the mixture of CaCO3 and CaSO4. These substances can not be recycled and do not have financial values, the simple managements such as landfill may cause the salinization and soil erosion. On the other side the secondary products of the magnetic method is the mixture of SO2 and CO2. This mixture is able to react with O2 under the catalysis of V2O5 to produce vitriol which can be the chemical engineering material. Furthurmore, this approach is extremely suitable for the Third World Countries. As we know, because of the financial problems the environmental problems in the Third World Countries usually are usually negelected. Controlling the sulfur dioxide is a heavy burdon on the companies and coutries of the Third World. If they can gain economic benefits from controlling SO2, it i s obvious that there would not be any problems on the popularize in the Third World countries. However, it also has some problems the most evident one is the problem of strainaway rate. Due to the restriction of circumstance, I can not do any experiment until now, so nobody knows how much the strainaway rate is. The most urgent and effective solution is doing experiments. Any valuable and successful technologies and skills are based on doing a mass of experiment to find problems and change the process. Moreover it seems that to reach the target mentioned above, there would be a simple but endless process, that means it is only suitable to the sweeping factories. Conclusion In conclusion, the way that author put forward obviously is a new aspect to regard the control of sulfur dioxide. After more than 100 years research on the traditional methods, they are all extremely ripe and difficult to improve. The magenic approach has the innate superiorities in comparision of the traditional ways. It is a definit physical technology which means there would not be any new extra pllutant to harm the environment. Moreover compared with the other new methods researched now, it is incredible convinient. All the basic building can be remaked from the existing equipments such as chimney and fluidized bed. In developing countries such as China and Africa countries which are not willing to pay attention on the environmenal protection, this technology can improve their enthusiasm, because they can gain a high economical benefits from the secondary products: vitrial with only a little investment. Although there are still some undeniable problems on this magenic way, it mus t be a valuable toward to research. The method mentioned in this paper is based on the 4 years experience in studying environmental subject of the author. Although the perspective and theoretical knowledge are sometimes naive and idealize, I strongly believe that this method must be valuable. Not only because the method itself, but also the aspect to deliberate and research. Environmental science is a wide ranged major which is not restricted in chemistry or biology, but also physics, physical chemistry, manage and biochemistry. The workers of protecting environment should expanse their own field of vision to all the relational knowledge instead of the major itself. In this career, not matter the organizations and physical properties, not matter the fields people consentrate on, as environment protection workers, we can all learn a lot of things and acquire inspiration from the whole science and engineering region.

The Use of Laughter in Poetry by Langston Hughes Essay -- Biography Bi

The Use of Laughter in Poetry by Langston Hughes Jessie Fauset explains in her essay The Gift of Laughter that black comedy developed not as a method for blacks to make people laugh, but as a necessary emotional outlet for black people to express their struggles and hardships. The "funny man" took on a much more serious emotion than appeared on the surface level. Comedy was one of the few means black people had available to them to express themselves. The paradoxical definition of laughter is applicable to all human beings; the limited means of expression is unique to those in an inferior place in society, such as the black Americans of the Harlem Renaissance. In a sense, what makes the struggles represented by the black comedian comic is the white audience member's ability "to retain mastery over himself and the situation" (Swabey 184). The white audience can laugh at the struggles and hardships on stage because of their refusal to accept the role they have played in the oppressions that caused them. Marie Collins Swabe y also writes in her book Comic Laughter that "By uncovering neglected hypocrisies, illusions, vanities, and deceptions in the behavior of persons and societies...while making us laugh, also removes in part our blindness with regard to certain factual and moral weaknesses in mankind" (11). Generally speaking, comedy makes us aware of certain character flaws. Fauset entertains this idea in her essay by wondering, "...if this picture of the black American as a living comic supplement has not been painted in order to camouflage the real feeling and knowledge of his white compatriot" (161).

Advantages of Being Bilingual Essay

In today’s society, twenty percent of the United States citizens are bilingual which demonstrates that America is rapidly growing. With all this growth, people are becoming fast learners when it comes to accumulating multiple languages. With the good comes the bad, therefore not all people are fortunate enough to learn and develop another language. By understanding and comprehending two languages you have achieved a big accomplishment. Being bilingual is important, especially in today’s society, because it allows people to become a dependable source – when it comes to their occupation. Being bilingual is also important because it shows the time and effort put into learning a new language, which shows devotion. Overall, being bilingual is a huge benefit because it allows people to work globally, increases job opportunities, and it opens the doors to a new culture. Many businesses around the United States associate with their workers and customers globally. Being bilingual is efficient because as the businesses expand, they need people to talk to others from across the globe. Plus, if you can speak a language someone else cannot then you are reliable for that business. Another plus about being bilingual in the cooperate world is they usually offer a higher pay or rank to people who know multiple languages. Most companies do that because it is hard to find people out there that can fluently speak another language and can handle the situation and if those people were not there it would be chaotic. Therefore by stating all of this information, companies need bilingual people because they do not just deal with English speaking people, they also speak to people from all over the globe which is an important role to fill in a corporate job. Studies have shown that bilingual people have better task switching capacities because of their acquired ability to inhibit one language while using another. In other words, speaking two languages forces your brain to recognize two different language systems. So, basically you become smarter. Researchers set lingual, arithmetical and physical tasks for 121 children, aged about nine, in Scotland and Sardinia, Italy. They found that the 62 bilingual children were significantly more successful in the tasks set for them. The study also assessed the children’s vocabulary, not so much for their  knowledge of words as their understanding of them. Again, there was a marked difference in the level of detail and richness in description from the bilingual pupils. Bilinguals score higher on average on tests involving creative thinking or problem-solving. The ability to translate abstract concepts from one language to another also develops the skill to look at tangible problems in more than one abstract way. Did you know that people who speak more than one language tend to make fewer errors in their driving? A side benefit, nonetheless! Bilingual adults and children seem to have social and emotional benefits like being able to internalize negative states like anxiety, aggression, anger, loneliness or low self-esteem less frequently. They have greater tolerance and less racism. It seems likely bilinguals would be more tolerant of differences and more open to diversity. According to studies, bilinguals tend to make better rational and financial decisions. Bilingual children are more likely to have an interest in the cultures that speak their second language, whether it is a â€Å"heritage† language or not. This can manifest early in life as an active interest in different educational avenues. Museums, fairs and street festivals, and even just visits to neighborhoods will have an inherent interest to bilingual children that monolingual children may not share. Children raised bilingual are more likely to show tolerance for other cultures at a young age. They play more easily with children who do not speak their language or who come from different socioeconomic backgrounds, and are more likely to show an interest in socializing beyond their established circle. In early childhood, this helps greatly with school, which focuses heavily on social skills in the lower grades. It can also help prevent disciplinary needs later in life — more tolerant children are, overall, better-behaved children. Bilingualism promotes overall cognitive development because a bilingual individual encounters the world from two different language perspectives, which prevents them from having a limited experience. This extended way of thinking facilitates the approach to cognitive problems and higher level of abstract thinking. Bilingual adults have a clear edge in business world. By being able to communicate in two languages, you have twice as many opportunities to land a great job. Being bilingual makes it easier to  travel, find a job and belong to this new global world inside and outside of the U.S. Children’s brains are primed for the necessary language skill developments in a way that adults’ aren’t. Many of the advantages described here will show up most strongly if you start bilingualism in your child’s early age (the earlier – the better!). Adults can acquire the same skills and strengths through bilingual training, but it happens much more slowly (how much spare time do we have in our busy adult lives?) and with a greater need for tedious repetition. In conclusion, Bilingual individuals are the new norm and if you are monolingual you are staying behind the curve. It’s adapt to survive or you will not make it in this new world order.
