Play and Long Haul Network Essay

Most people don’t care about how they connect to other players when they log on to play Halo 4 or Call of duty. I am going to explain how the game player at home connects to the game player Japan or California. Information technology has expanded a whole lot from when I was a kid and there was no such thing as online game playing. Then it was only to play a game computer with really bad graphics. The people didn’t really look like people and the background was just plain. Well since it has grown so has online game playing. When you log into your Xbox live account you are giving your credentials that allows you access to their sever. This is established by connecting to the internet through your cable modem or through a wireless connection. This sends your credentials in a packet from your house through a copper or fiber optic cable to a local exchange. Once it goes into the local exchange it is then sent to an aggregating point in the city and throughout the country over a regional network. Your packet is then aggregated and transported over a long haul network so that it will reach the launching point at the country shoreline, where it is then sent over more cabling connecting the US to Japan, underwater, over the ocean network. Once it arrives in Japan, it is then distributed back to the long haul network or regional network, to the local exchange, and then back to you at your home computer or Xbox. The reason the gamers see everything in real time is because all of this happens superfast. When this occurs it happens mostly over fiber optic cable. This means that it moves at the speed of light, for example it takes about 30 to 40 milliseconds to go from New York to London. That is taking into account the undersea transmissions portion and delays caused by aggregating and switching equipment. So now you know exactly what happens to your data when you are playing a game online. This process works for all data that is transmitted via Xbox or computer. That is why when you are playing sometimes you can experience lags of data. All of this is also how you get to connect with other gamers all over the world without all these processes there would be no online gaming and a lot of unhappy kids.

Advantages Or Disadvantages Of Internet

The computer was a fundamental innovation which flipped the world upside down. Some argue that it is a blessing whilst others insist that in spite of all the commodities it brought about with it, it is a curse.Computers are necessary in all spheres of life. To begin with, the computer has a vast array of software which is beneficial for both young and old people. Young children can enjoy playing games on the computer whilst beginning to learn reading and writing. It is much safer that having children playing around in the streets since there is a high risk of someone being hurt. Computer studies are proliferating in our schools because the computer has become so important throughout our lives.In business, the computer, is a surely a real blessing. Apart from being more organized nowadays one can also extend his business and adverts throughout the world with e-commerce. Creating a website is easy and cheap to sustain. One can also work from the commodity of his home as well as doing s hopping and having the products delivered in a short time.It has become second nature for us to chat with friends and socialize through networks. One can communicate with his relatives abroad easier and it is far cheaper than phoning overseas. For students it is a real gem. Computers are a huge source of information. There is software such as encyclopedias which are very useful when doing a research for school. Besides, one can also spend less time searching in vain in books.It is also a truism that computers have their negative aspects as well. Being seated on the chair in front of the screen for a long time can lead to back problems later in life. One can even damage the wrist. Another disadvantage is that children of the computer era are lazier than the ones before. They are not adventurous at all and are brought up with the mentality of living life without pain or any effort.Many children are obsessed with gaming and some become spendthrifts as time passes by because they buy pl enty of games and upgrades for their computers. On the internet there is not enough data protection and having children surfing the net on their own is bad. Parents must be aware of the potential harm their children may be exposed to and they must be computer literate for the sake of the benefit of their own children.Life without computers is unimaginable and in the long run the computer is very useful. Although it has some negative effects, it needs to be utilized properly with proper supervision and knowledge so that all the benefits of the computer are exploited.

Deciding to decide review Essay Example | Topics and Well Written Essays - 500 words

Deciding to decide review - Essay Example Justification of petitions at the Supreme Court must meet clearly outlined criteria. This is the only way that a case on certiorari will be deemed acceptable at the Supreme Court. In the event that the Supreme Court does not necessarily have to be involved, then higher courts more or less apply the same process in justifying the certworthiness of certiorari cases. According to Perry (1991), a case on certiorari is said to be certworthy if it meets the circuit conflict, importance, and egregiousness criteria for cert. Certiorari cases capture the attention of the higher courts, and especially the Supreme Court, if they exhibit critical circuit conflicts. The availability of a circuit conflict does not automatically justify certworthiness. Higher courts or the Supreme Court for that matter has its evaluative measures that determine the criticality of the conflict, subsequently informing whether or not cert. is granted. Conflicts within and across circuits may or may not be deemed necessary for consideration by the higher courts. However, the justification process is clearly outlined so that an ultimate decision is reached from the facts, issues, concerns, or conflicts presented on the table. The importance of the certiorari case is another justification factor considered in the process of determining the certworthiness of the case. A case’s uniqueness, political and societal importance, and legal importance of a petition (Perry, 1991) are the primary factors that inform the importance of a certiorari case. Here, the implications of the petition are prioritized. Notably, the depth of the matter may not count as much. The political, societal, and legal factors subject to a certiorari case make all the difference. The process of determining the certworthiness of a certiorari case is undoubtedly intensive and extensive. What matters to the higher courts or the Supreme Court in particular are the three

Marketing Concepts Essay Example | Topics and Well Written Essays - 2000 words

Marketing Concepts - Essay Example In the UK, 28% of consumers own a smartphone and by 2015 iPhones will make up 11% of all total devices used in the UK.† (Mintel, 2010) The trend in sales has proved that customers are now looking at mobile phone as a device beyond a small instrument that helps to make phone calls. In fact, making calls have become just small of the many functions of mobile phones. Mobile phones are now a total communication and mobility solution. This trend in the industry was driven by the smart phone of iPhone, Nokia, Samsung, Blackberry and other players. This report will discuss the macro and micro environmental changes in the industry and its impacts on the marketing activities of smart phone companies. The report will be discussed with particular reference to Apple iPhone and RIM Blackberry. Mobile phone industry is one of the fastest growing and fastest changing industries in the world. The products become outdated very quickly than in any other domain. Innovation in products, services a nd marketing activities are most common in the industry. Smart phones are the power houses of mobile phone market. Globally, â€Å"Feature phones still represent the majority of mobile phone shipments, even though they are under increasing pressure from smartphones.† (Wauters, 2011) IPhone and Blackberry are among the leading smart phone makers of the world though Blackberry’s market share is slowly being taken over by Samsung. This report will deal primarily with the environmental factors affecting the smart phone industry. The report will also deal with the importance of market segmentation, targeting and positioning in the industry. The later part of the report will discuss the importance of adopting a right marketing mix for the smart phone industry. Environmental Factors and their Impact The major macro environmental factors that affect marketing in the mobile phone market are technology, economic factors, education and employment levels and social factors. (Zain Books, 2011) Technology is the primary factor that drives the handset industry. Recent developments in the market have shown that Apple has come up with the software called ‘siri’ which is expected to take the market by storm. Such developments will force Blackberry to introduce similar technology or any other differentiating factor on its further models and marketing. Economic condition is the next major factor that impacts the marketing. A slowing economy will usually dent the demand for handsets in the market. A slow economy is usually followed by low disposable income in the hands of the consumers. Therefore, the companies will mostly reduce their marketing spending in order to reduce cost and improve margin. Education and employment levels determine whether the consumers will have enough knowledge and disposable income to purchase mobile phones. Companies like Apple and Blackberry will have to decide on the pricing and product features based on the educational and employment level of the customers. The next macro environmental factor that has an impact on the marketing decisions of handset companies are social factors. The social set up and reference groups create a huge impact on the purchasing decisions of consumers. (Tutor2u, 2011) Therefore, the marketing activities of a company in one region are entirely different from that of the other region. For instance, the theme of iPhone advertisement in United States will be different from what it is in India. The main reason is the difference between social

Value of entrepreneurship to emerging economies Assignment

Value of entrepreneurship to emerging economies - Assignment Example A very unique feature and characteristic of the global market, a perfect reflection of which could be paralleled to the structure of any country is that it is made up people from different socio-economic backgrounds, each of which plays a contributory role towards the collective success of the market. As far as emerging markets are concerned, they can be compared to those players on the market who trade in not so huge forms of business, but yet, having the little contributions they bring on the market, significant enough to be counted as part of collective growth and development (Sandee, Isdijoso and Sulandjari, 2002). But for the roles and contributions of these emerging markets to be felt in a perfect sense, there are some key inputs that must be present. One of these is the contributory roles that entrepreneurship plays in the emerging markets (Acs and Szerb, 2007). Generally, an emerging market may be described as a country that has social and economic activity climate that is se t on the lines of rapid growth and development (Liedholm, 2002). Because entrepreneurs have a common goal of investing in markets, their contributions to these markets have been studied in several works of literature. In this paper, five major points that make a case for the value of entrepreneurship in Brazil as an emerging market are discussed. Increased Competitive Pressure In Brazil, the political environment allows that there can be as many entrepreneurship openings as possible. With such policy, the private sector, most of which have been controlled by entrepreneurship have had so much grounds to operate. Currently, there are several entrepreneurial based companies and businesses operating in the country. Generally, the size and economic worth of these entrepreneurial businesses are not seen to be as huge as those that are presented by multinational and international companies (Valliere and Peterson, 2009). However, because the entrepreneurial businesses have their own market and client base, it has always been important for them to engage in increased competitive marketing to ensure their survival. Economically, as these increased competitive pressures take place, entrepreneurs are forced to be rigorous on the emerging market, injecting capital into their businesses. On a larger scale, the fact that these enterprises are competitive enough and have higher asset base, revenues, capital, and manpower base, they contribute to the collective expansion and growth of the emerging markets in which they find themselves (Sandee, Isdijoso and Sulandjari, 2002). In Brazil, there are multinational companies that started merely as enterprises but due to the competition that they received from other enterprises and the need for them to be proactive in their growth; they have today become key stakeholders in that emerging market. Exploitation of Innovation Valliere and Peterson (2009) note that most entrepreneurial based companies and businesses in emerging markets ar e forced to engage in the exploitation of innovation because that is the only way by which they can be competitive against traditional multinational companies. Through the exploitation of innovation, these enterprises have critically gone into research and development to understudy marketing trends and principles that works best with the local markets in which they operate (Williams, 2009). Part of the exploitation of innovation has also included the need to use highly skilled and talented human resource within the corridors of the markets in which they find themselves to growth their business. Invariably, entrepreneurship has been valuable in ensuring that the emerging markets as a collective entity, rather than their enterprises alone are borne on the wings of innovative business. As it will be noted a major characteristic of developed markets is the abundance of innovation (Valliere and Pet

Code of Ethics Research Paper Example | Topics and Well Written Essays - 2500 words

Code of Ethics - Research Paper Example This paper’s focal point is to create an appropriate code of ethics that would be perfectly suited for any business. All the staff, board members, and volunteer members that work within an organization must encompass virtues that illustrate integrity in their personal and professional relations. Honesty and transparency are the most important virtues in this regard. The focal point of existence for an organization needs consideration. For instance, in an online banking organization, this could be to ensure that clients receive banking service provision of the highest quality from the comfort of their homes. The organization’s code should be well within & aims to fulfill all the requirements sets within the State’s /Country’s Constitution. It ought to regard of the necessary laws and regulations (Bailey, 2011). Information concerning financial and social dealing of an organization should be provided to the media, public, and all stakeholders in an efficient and timely procedure. Any variations in management or strategies are to be provided to the parties stated with immediate effect (McCloskey, 2006). An organization should be conscious to ensure that there is no discrimination in the processes of hiring, firing, retention, and promotion. All the staff, volunteers, clients, as well as board members of the organization ought to be accorded, given equal opportunity. While in the process of solicitation, an organization must maintain truthfulness when relating with its donors. The organization must respect all the concerns of donors, with regard to privacy, and only expect funds that are in direct inclination with intents of the donor. The statement of values regarded above is based solely on humanity. Formulation of the principles occurs after incorporation of the process of social imagination. This is whereby one

Opportunity Cost Term Paper Example | Topics and Well Written Essays - 1750 words

Opportunity Cost - Term Paper Example   This is due to the fact that whereas the needs could be unlimited, the resources will always be scarce such that there is not one time when a person can afford to satisfy all his needs without sacrificing (Bloom 2004 p 26).   In this essay, various examples have been used to substantiate the definition of opportunity cost which is the value of the sacrificed alternative in favor of the decision or choice made.   It goes on to compare the relationship between scarcity and opportunity cost thereby showing that scarcity is the major factor that contributes to situations that result to households and firms undergoing opportunity cost.   The essay also continues to examine the environmental impacts that are not of financial nature but which exerts pressure on the choices and alternatives which are available. A case of oil mining has been used as an example that has both positive and negative impacts on the economy and the ecosystem respectively, factors that can create conflicts between the investor and the environmentalists. In some cases like this, it has been noted that the opportunity cost can be influenced by availing incentives so as to add weight to the importance of choosing an alternative over another. Further areas of research regarding opportunity cost have also been suggested in this essay.   Opportunity cost  Opportunity cost can be referred to as the foregone cost or a decision made over a range of alternatives favoring one of the alternatives.

Gentrification Essay Example | Topics and Well Written Essays - 1750 words

Gentrification - Essay Example What is Gentrification? Through researching this phenomenon, one discovers that there is no finite definition of the term. The term was coined in 1964 by sociologist Ruth Glass when she used examples of London Districts as illustrations to define what the term meant: One by one, many of the working quarters of London have been invaded by the middle-class upper and lower. Shabby modest mews and cottages-two rooms up an two rooms down-have taken over, when their leases have expired, and become elegant, expensive residences [†¦] once this process of gentrification starts in a district it goes on rapidly until all or most of the working class occupiers are displaced and the whole social character is changed. In the Encyclopedia of Housing it is defined as â€Å"the process by which central urban neighborhoods that have undergone disinvestments and economic decline experience a reversal, reinvestments, and the in-migration of relatively well off, middle and upper middle class popula tion† (Smith) Then Hammel and Wyly difine gentrification as â€Å"the replacement of low-income, inner-city working class residents by middle-or upper –class households, either through the market for existing housing or demolition to make way for new up-scale housing construction: (Hammel) And the United States Department of Housing and Urban development defines gentrification as â€Å"the process by which a neighborhood occupied by low-income households undergo revitalization or reinvestment through the arrival of upper-income households†.... predominant common thread and motivation point to, (3) influx or the relatively affluent or gentry and (4) an increase in investment. Friedmann who lays down a hypothetical framework on which to build a study of global cities, used one of his components to his seven part theory the emergence of a bifurcated (to divide into two branches) service industry in major cities, which is composed of on the one hand, a high percentage of professionals specialized in control functions and, on the other, a vast army of low-skilled workers engaged inpersonal services[that] cater to the privileged classes for those whose sake the city primarily exists. (Friedmann) In Amsterdam social cleansing seems to be the appropriate name for deliberate policies aimed at removing a section of the population-a criminal underclass, or those with low-incomes. It is often inspired by a belief that a city (and its administration) has failed, if such people live there. The emergence of active policies to change the population mix in an entire city is related to the neoliberal idea that cities are a sort of business, competing in a global market of cities, and that successful cities have successful inhabitants. Unlike gentrification, Social cleansing is always government initiated. However, in Amsterdam, it is difficult to discern the difference between the two in either stated purpose or actual implementation. Low income bans in Amsterdam is a legal instrument. The first phase of gentrification in Amsterdam is where art and culture areprominent-the first art gallery in a working class neighborhood is a classic sign of

The Youth Today - Are They More Impatient Than a Few Decades Ago Essay Example for Free

The Youth Today Are They More Impatient Than a Few Decades Ago Essay It has been rightly said that we spend the first half of our lives trying to understand the older generation, and the rest half in understanding the younger generation. Every age has its own charm. Youth has always felt somewhat exasperated with age and age has always been suspicious of youth. With their natural ebullience and impatience, a majority of young people are keen to act and learn on their own rather being guided by the experience of elders. The older people being more at home with words rather than action often make noises about the youth being impatient and rude. In every generation, old men are found to shaking their hoary heads and waxing nostalgic about the good old days when youth of their time knew better and showed due reverence to age and tradition. Some of the charges brought against modern youth are that they represent a rudderless generation without any ideals to live by or cause to live for. They are afflicted with compulsive irreverence which manifests itself in increasing defiance of parental authority and revolt against established social norms. On the slightest pretext they take to streets, indulging in violence. They want to attract attention through unconventional behavior. They are becoming a generation of drug addicts and have developed an aversion to honest hard work, ever on the look out to have something for nothing. Its no longer anxious youth going forth, into a hostile world. Now its hostile youth going forth into an anxious world this is not sure what to expect from it. If we come to think about it, it is not only the youth which is restless, human society itself is in a state of flux. Growing affluence in developed societies has generated among the youth there a restlessness which pined for instant rewards. The children get all the money they need from parents and seldom face the need to work for a living. In the under developed countries also, young generation are feeling disgruntled because their visions of a happy future are being obliterated either by internal strife or political opportunism. This provokes the youth to protest against rampant corruption in society and the denial of social justice. In the circumstances, is it to be wondered at if all talk of dedication to ideals, renewed moral vigor and basic virtues leaves the youth cold and unconvinced? They are no longer prepared to blindly accept whatever their elders choose to ram down their throats. They are prone to subject to critical review all the social and political values they are called upon to accept. When they se high sounding principles invariably being ignored for expediency, political leaders deliberately hoodwinking the masses, vested interests being allowed to frustrate the state of every step, corruption common in high places and other gaping differences between promise and performance, they naturally become cynical and clamor for change. Students form a very important group among the youth of all nations. Their biggest and most legitimate grievance is that what they learn after putting so much time, effort and money has very little relevance to the realities of life with which they come face to face after leaving the university. It is but natural that they should want to have a say in determining what should be taught so that it has some relevance to their future. They would no longer tolerate politickers veiled as teachers. They consider themselves quite capable of looking after themselves. If we look at youth today in the light of foregoing, it will be apparent that it’s not the young alone who are to blame for the state of mind in which we find them. They may well be charged with being ignorance of what they want. Theirs is a movement of protest against hypocrisy and lack of integrity in their elders. Evidently, this concern for the future and this anxiety to rescue life from hypocrisy is very laudable indeed. But it cannot be said that the young are all the time guided by such high purpose. Dissent is required in fact obligatory when things go wrong. Violence comes natural to youth. The young, supremely sure that the authority against which they are up in arms is unjust and oppressive and feeling cretin of the correctness of their own stand, react emotionally. The intensity of their feelings is such that it fills them with hatred and they turn to violence. On the whole, the younger generation today is much misunderstood and more maligned than it deserves. The world which it is going to inherit will be immensely more exciting than the world of its predecessors ever was or could be. At the same time, life will present to it a much bigger and far more complex challenge. It would not do to condemn it and find fault with it that is easy enough. What is really important is that it is treated with understanding so that it can develop to faculties to reshape the world it is going to inherit in accordance with its noblest vision.

Social Structure Of Mesopotamians And Egyptians History Essay

Social Structure Of Mesopotamians And Egyptians History Essay The social structure from one empire to another can vary a lot. It depended mostly on the wealth of the empire, the way the empire came to be, and other factors. In the case of the Mesopotamians and Egyptians, there were some similarities, but also some differences. Those differences included the social roles that women played in their respective empires, among other things. The Mesopotamian Empire had many opportunities to accumulate wealth. Thus, their social structure became much more clearly defined than other Neolithic communities. In early Mesopotamia, the ruling class consisted of kings and nobles who previously were great warriors. Later on, however, royal status became hereditary. The royal class was looked upon highly, and people often thought of them as part divine. Next in the social chain were the priests and priestesses, many of whom were related to the rulers in some way. Their main responsibility was to intervene with the gods and ensure good fortune for their communities. In exchange for this service, priests and priestesses led a luxurious life. Also in the social structure were free commoners. They mostly worked as farmers in the countryside or in other manufacturing jobs. Dependent clients were another class in the social structure. They possessed no property and usually worked as agricultural laborers. The last rung on the social lad der were slaves. Slaves came from three main sources: prisoners of war, convicted criminals, and people who sold themselves into slavery in order to satisfy their obligations. Most slaves were domestic servants in wealthy households, but some worked as agricultural laborers as well. The Egyptian social structure had some similarities and differences. Like the Mesopotamians, Egyptians had a well-defined social class system. Also, the Egyptian peasants and slaves played a similar role in society as the Mesopotamian peasants and slaves. However, the organization of the ruling classes differed significantly. While Mesopotamians had a series of urban kings, Egyptians had one supreme, central ruler called the pharaoh. The Egyptians had no need for nobles since the pharaoh was the absolute ruler. Instead, Egyptians relied on professional military forces and government officials. This allowed for individuals of common birth to have a higher likelihood of attaining high positions compared to Mesopotamians. The differences between the social classes of the Egyptians and Mesopotamians allowed each of them to have their own unique empires. The conditions of women were also very different between the Mesopotamians and the Egyptians. In Mesopotamia, women had subordinate legal status. However, they did have a certain amount of influence politically, economically, and socially. At ruling courts in Mesopotamia, women sometimes advised the government. Other held great power as high-ranking priestesses. Other Mesopotamian women were able to receive a formal education and pursue a career. Unfortunately, Mesopotamian men began to progressively tighten their control over the social and sexual behavior of women in the second millennium B.C.E. Egyptian women were able to have an even bigger impact on society. There was a time when a woman pharaoh took power (Queen Hatshepsut). Other women also had substantial amounts of power as priestesses. Some got formal educations as well. The Mesopotamian and Egyptian social structures had both differences and similarities. Both empires social systems were well-defined, and included similar roles for peasants and slaves. However, the rest of their system was somewhat different, especially their ruling classes. Though both gave women some social influence, Egyptians provided more powerful opportunities for women. Both empires had a successful and well-enforced social class system.

Jealousy and Self-Love in My Last Duchess by Robert Browning Essay

Robert Browning's dramatic poem "My Last Duchess" defines how extremely a person may lose touch with reality, as a result of jealousy and self-love. Â  This central thought is achieved through an aristocrat's conversation with a visitor concerning a painting of his ex-wife; within the conversation, the aristocrat--Alfonso II, Duke of Ferrara--reveals that he has been a key figure in the murder of his late wife. Â  The Duke's sense of reality and his misuse of power stand as important facets within the fabrication of the central idea. The Duke almost seems to be encouraging the reader to focus on the fact that his sense of reality is defective. Â  He begins pressing this notion to the reader within the early stages of the poem, while talking to the visitor about a portrait of his murdered wife: "I call that piece a wonder now: Fra Pandolf's hands worked busily a day, and there she stands"(Browning 695-696). Â  Upon reading this so early in the Duke's conversation, the reader is taken back; how could an individual be more interested in the quality of work in a piece of art than his dead...

Notes on Cry Essay

The dance’s intent is to portray the struggle & strength of the African American women who were in the slave trade; how women so enslaved & trapped can still manage to be so free. â€Å"I heard about lynching’s, Having that kind of experience as a child left a feeling of rage in me that I think pervades my work† Alvin Ailey. â€Å"She rises again to wear the cloth as a shawl, then steps on its ends as if bound by it to the ground†¦Ã¢â‚¬  â€Å"The final posture mirrors the opening posture of the dance, suggesting a cyclical inevitable progression of frustration and despair†¦Ã¢â‚¬  Ailey has abstracted this narrative to portray the woman’s despair.

As a depiction of contemporary African American  identity, the dance liberated audience and dancer in its  modernistic layering of movement genres, especially its  conspicuous use of neoAfrican  body part isolations.† In this work there are three distinct sections and for each new section, there is a new song that is played. The songs used in this work are ‘Something About John Coltrane’ by Alice Coltrane, ‘Been On A Train’ by Laura Nyro and ‘Right On. Be Free.’ by The Voices Of East Harlem. In a couple of these songs the word ‘north’ is used quite a bit. My personal  interpretation is that these slaves perhaps saw freedom and/or refuge in North America, wished to be there but something stopped them.  She clearly demonstrated Ailey’s mother’s struggles as well as any other African American woman’s struggles at the time as a slave to their fight for freedom.

How to Lie with Statistics

A Synopsis of How to Lie with Statistics by Darrell Huff When most people hear or read a statistic, they quickly have to decide if the numbers listed are valid or invalid. It is usually assumed that the author of the statistic is knowledgeable in the field to which the statistic pertains. However, on many occasions, the statistic is false, due to the author’s wording. Darrell Huff’s novel How to Lie with Statistics is a manual that can help individuals catch these lies. The novel allows readers to solve marketing ploys and dismiss certain statistics as faulty.The first chapter focuses on bias. The book states that all statistics are based on samples, and these samples have bias. This means that no matter what the reader will have a biased opinion. This bias is spawned from the respondents replying dishonesty, the author choosing a sample that gives better results, and the availability of data. Huff uses a survey of readership of two magazines, which had refuting results . This is because, due to the readers’ personal biases, they answered the survey dishonestly.This example closes the chapter, teaching readers to always assume that the sample has a bias. The second chapter focuses on averages. It states that there are actually three types of averages: mean, median, and mode. Mean is the arithmetic average. Median is the name given to the midpoint of the date. Finally, mode is the data point that occurs the most often in the data. Thus, the type of average used can alter the results of the statistics. The next chapter explains how sample data is chosen to prove certain results.Many marketing campaigns use this technique. They choose sample sizes that give their wanted results. Huff’s solution is that one must determine if the information is a discrete quantity or if a range is involved. The following chapter discusses errors in measurement. It explains two measures for measuring error: Probable Error and Standard Error. The probable er ror uses the error in the measuring device used to measure the error in the measurement. The standard error is the standard deviation of the sampling distribution of a statistic.Chapter five explains how to manipulate a graph in order to show the results one wants. For example, if one was using a line graph to show a 10% climb, they could remove the unused parts of the graph to make their results seem more extreme. The next chapter discusses how two-dimensional images can deceive readers. A picture may be increased in all dimensions, making it seem much larger than it really is, giving the impression of a greater increase. Chapter seven focuses on the semi-attached figure.Simply put, if one cannot prove what they wish to prove, they can merely prove something else and then give the impression that these two things are the same. Huff uses cold medicine as an example. A pharmacist wants the reader to believe that their medicine cures the cold, but instead the label reads that the medi cine kills 32, 132 cold germs. The pharmacist then hopes that the reader makes the assumption that because the medicine kills such a high number of germs, then it cures the cold. Huff is therefore teaching not to assume.The following chapter focuses on cause and effect. Huff stresses that readers must ask for when certain data was collected and if the amount of data was adequate for the entirety of the experiment. Chapter nine teachers readers how to ‘statisticulate’, meaning how to manipulate readers by using statistics. This chapter is essentially a list of what to look for when determining the validity of a statistic. Huff explains various tricks, such as measuring profit on a cost price and how income calculations mislead by using children of a family as the average.The final chapter instructs readers on how to talk back to a statistic. Huff emphasizes that readers must ask who the author his and how did he come to collect the knowledge listed in the statistic. Also , he encourages readers to question if someone changed the subject of the statistic. Finally, he explains that one must be able to understand the data presented, and if it does not make sense, then it is most likely untrue. Overall, Huff assists readers in how to determine if a statistic is valid or invalid. Though the book was published over fifty years ago, these methods are still in use.

Culture similarities and differences in early East Asian history Essay

Culture refers to people’s way of life. Culture is transmitted from one generation to another. Culture is leaned. Culture is a means through which society share values, beliefs, customs, behavior and artifacts. Tradition refers to the process of doing an action more than once. For example, repeating an action now and again makes it be a tradition. Going home to celebrate festivals together as a family could become a tradition if every festive you go home. Culture in the Asian countries rotates around art, beauty, medicine and cuisines. Chinese culture In the Chinese society, there are five necessities that define their culture. These necessities are: Food, clothing, housing, transportation and education. Chinese cooking is of two types. That is, Northern and Southern cooking styles. Northern dishes have a lot of oil and garlic and vinegar are usually pronounced. Pasta is valued in the Northern style of cooking. In the Southern cooking styles, chili peppers are valued. Rice and rice products are usually used as accompaniments. In Chinese cooking, color, smell and taste are given same value in meal preparation. Most of the time, a meal will include three to five colors. Most valued during cooking is the preservation of the fresh natural taste of the spices. The three properties of color, aroma and taste are not only the issues valued in Chinese cooking, but nutrition is of great importance. According to Shang dynasty(Chinese culture 16th to 11th B. C ) Yi Yin, he related the five tastes of sweet, sour, bitter, piquant and salty to the nutritional needs of the five major system organs of the body( the heart, liver, spleen, lungs and kidneys) and emphasized their function in maintaining good physical health. Most of the vegetables used in Chinese cooking such as garlic, dried lily buds, tree fungus have components that help in preventing and alleviating diseases. Chinese culture believes that food and medicine share the same origin. Chinese culture has got certain restrictions associated with eating. That is, meals taken while seated, sitting arrangement is based on age and gender. The dishes are arranged per table basis with a table capturing around ten to twelve people. Chinese dressing symbolizes a meaning of its own. The main types of Chinese traditional dressing are: pien-fu, long robe and shen-i. The pien-fu is a ceremonial costume in which one had to wear a tunic like top that extends to the knees and a skirt that touches to the ankles. A pien is a cylindrical cap. Similarities between these clothing are wide cut and voluminous sleeves with straight lines. They are also made more attracting by adding ornaments onto them such as doing embroidery along the edges, decorated bands, draped cloths and silk. In the traditional Chinese clothing, dull colors were favored to light colors. Bright colored clothes were used by common people around the houses. Chinese culture associated certain colors with specific times such as green symbolizes spring, white representing autumn, black for winter and red for summer. Traditional Chinese housing is characterized by a rectangular- shaped unit space that is joined into a house. The Chinese structures combine rectangular patterns of different sizes and positioned in order of preference, with every stage clearly distinguished. In the traditional buildings, the principle of balance and symmetry is taken into consideration. The main building is the axis with the other buildings being joined to the sides to form wings on both sides serving as the main room and yards. All other Chinese structure such the church, residential houses, palaces and official structures follow the same design. The interior space is allocated in away that it defines the Chinese social setting and ethics. For instance the main room is for the master, elder members of the master occupy the backyard of the main room while the junior members live in the right and left wings with the most senior occupying the left wing and the others right wing. Certain pronounced features of Chinese structures are its wooden structural frame with pillars and a beam, and mud made walls surrounding the three faces. The main doors and windows are constructed on the front face of the building. Woods is used in Chinese structures because they believe that wood represents life which is the essence of their culture. Chinese people build houses that have deep and over hanging roofs. Because of this, they came up with their own way of giving the roofs support. This invention is called ‘tou-kung’, which goes up stage by stage from pillar to pillar. The tou-kung gives support to the structure and at the same time acts as a unique and attractive ornamentation. The significance of using wood in the Chinese construction is that the size of the rooms depends on the wooden frame used. Again, color is applied to prevent the wood and third is the skill of building a structure on a platform to prevent moisture. The use of various colors in Chinese buildings has both symbolic and aesthetic meaning. In the transport system, china did not have any kind of wheeled vehicles until importation of the chariot was done from central Asia in the period of 1200bc. Scholars also ague that early Bronze Age china did not own the skills of the chariot and never invented any other means of transportation such as wheelbarrows or carts. For example, Edward Shaughessy found out that during the Shang periods, â€Å"there is absolutely no artifactual evidence for other types of wheeled conveyance†. In the 19th and 20th centuries, rickshaws became most popular but were later overtaken by cycle rickshaws and auto rickshaws. Bicycles today are so many in china that, they cause traffic jams. Today china use both railways and waterways as modes of transportation. Education system in china is socialist oriented with a classroom having a capacity of about 50 students. Learning is always through group work to promote team spirit and cooperation among the students. Chinese value education because they believe it is a stepping stone to success. In china excellence is the main purpose for education. This is because they aim at producing responsible citizens who can give quality service to society. That is, a student excels to benefit the country but not him or her. Japanese culture Japanese culture is largely borrowed from china but Japanese culture is mainly influenced by its language. Japanese language is a combination of subset languages that are borrowed from china. That is, hiragana, katakana and kanji. Japanese usually have different types of traditional foods for various seasons such as osechi-ryori foods for New Year, kabochi on winters, weeding foods and mother dinners. Japanese also use spices in food preparation so as to make it tasty and give an appetizing smell. Japanese have got eating manners that they expect people to adhere to when eating. These tips on how to eat varies from one meal to another. Their dishes include sushi, tempura and teriyaki. Japanese performing art is characterized by costumes, mask and stylish gestures. Their four theatres are noh, kabuki and bunraku. Japanese way of building is also an important aspect of their culture. It was heavily influenced by the Chinese architecture and examples of these are seen in the temples, shrines and castles. In terms of clothing, Japanese wear kimono. Kimono implies â€Å"something to wear. † Initially Japanese used the word kimono to refer to all types of dressing but today it only implies long dress that is worn by men, women and children. Kimono is available in different colors with men prioritizing dark colors and women prioritizing brighter colors. The summer kimono is light and it’s called yukata. In the world of sports, methods that were used to train warriors in the past have been organized into sports. For example, kenjutsu, kyudo, and sumo. Again, Japanese popular culture presents a link to the past. Favorite films, television programs and music are all established from the traditions. Japanese also have got aculture of making sculptures. The oldest sculpture made is known as Amitabha in the Zenko-ji temple and it is made of wood. Japanese value wood and it has been used in Japan as one of the main materials by architectures. Other materials that have also been used are stone and pottery. They also have a flower arrangement art known as Ikebana which emphasizes on harmony, rhythm and color use. Comparison between the two cultures However there are certain variations in the two cultures. That is, in Japan buildings are structured around grand palaces while in china, they are based on the concept of walled cities. In terms of food, their primary dish is rice even though the mode of preparation is different. In their concept of beauty, Japanese considers beauty as a concept that is temporary to life. They use a symbol known as sakura (cherry blossom) to express the fleeting property and wilting nature of beauty. But in china, beauty is part of nature and this explains the common paintings of lions, cats and tigers. Musically, Japanese love more vocal music that takes its routes from dramatic styles such as Noh, Kabukl, and Bunraku while Chinese traditional music is dominated by instruments such as the flute and oboe. Traditionally the two societies do not like each other. Japanese have a collective kind of culture than Chinese. Both Chinese and Japanese up hold respect for tradition, family and beauty but Japanese tend to be consistent with the practice. Taking the above discussion into consideration, I wish to conclude that the two cultures are different even though Japanese culture was influenced mainly by Chinese culture, References Chinese culture and tradition.

Bartolome de las Casas’s Destruction of the Indies Essay

Bartolomà © de las Casas was a Spanish historian and a social reformer who was writing in the 16th century, during the time of the Spanish occupation of the Indies. In A Short Account of the Destruction of the Indies, Casas provides a scathing commentary on the cruelty exercised by the Spanish colonizers on the natives of Hispaniola—as well as explain the aims that motivated this behavior. The account acts as not only an observation on the practices of the colonizers, but is also a reflection of the imperial policies of the Spanish Empire. Through writing A Short Account of the Destruction of the Indies, Casas aims at bringing the Spanish Crown’s attention to the atrocities committed by the citizens of the empire on the natives. In keeping with that aim, he utilizes a rhetoric that seeks to arouse the sympathy of his readers towards the natives and a sense of horror over how they are being treated. Right from the beginning of the account, in the preface, he paints an i mage of the natives as being simple, and harmless. He describes them as, â€Å"the simplest people in the world†¦they are without malice or guilt†¦never quarrelsome or belligerent or boisterous, they harbour no grudges†¦indeed the notions of revenge, rancour and hatred are quite foreign to them†. In contrast to that, he describes the Spaniards as â€Å"ravening wolves† who fell upon the natives like â€Å"tigers or savage lions who had not eaten meat for days .â€Å" Casas sets up a comparison between the helplessness of the natives and the savagery of the Spaniards, and this comparison holds throughout the document. Examples of this comparison are in the frequent accounts he gives of the before and after native population levels once the Spanish occupy an area—â€Å"when the Spanish first journeyed here, the indigenous population of the island of Hispaniola stood at some three million; today only two hundred survive† or â€Å"not a living soul remains today on any of the islands of the Bahamas.† Casas uses concrete numbers in describing the decline in the population level, in the number deaths—he does this as a means of stressing the official nature of the document, to lend it a sense authority. These numbers also help in giving his reade rs a very clear idea of the terrifying extent of the Spanish cruelty. He enumerates the different ways through which the locals are being exterminated, which gives a fair idea of the general colonial practices in the Indies— through â€Å"forcible expatriation†, â€Å"unjust†¦tyrannical war,† working the natives to the  point of death—Casas gives an example of a man who worked the natives under him so hard that within a month, out of three hundred, only thirty survived. More importantly, Casas reveals the motives behind the widespread cruelty as being simple, materialistic greed. He explains that the greed for the gold that the natives have is the driving force behind the actions of the Spanish. The one instance that effectively reflects this fanatical greed is of the local lord who makes an offering of nine thousand castilians to the Spanish and is still seized and tortured for more gold—â€Å"tying him in a sitting position to a stake set in the ground, lit a fire under his outstretched feet to induce him to hand over yet more gold†¦when he produced no further gold, they carried on until all the marrow ran out through the soles of his feet.† What is worth noting is that Casas when first talking about this greed, refers to the Spanish as Christians—â€Å"the reason the Christians have murdered on such a vast scale and killed anyone and everyone in their way is purely and simply greed.† Casas obviously uses the term â€Å"Christian† ironically to draw attention to the un-Christian behavior that the Spanish are displaying in the colonies. Casas was the Bishop of Chiapas. He was a clerical man, and so his primary concern was the un-Christian activities that were taking place in the colonies. He exclaims that the colonizers have â€Å"little concern over their [natives] souls as for their bodies, all the millions that have perished, having gone to their deaths with no knowledge of God.† This clearly defines exactly what A Short Account of the Destruction of the Indies as a text is—it is not a text that is arguing for equal rights, it is instead a text that shows the priorities and concerns of a man living under the Spanish Empire at the time. Casas views the natives not as people equal to the Spaniards, but as potential Christians. He describes them as being, â€Å"innocent and pure in mind and have a lively intelligence, all of which makes them particularly receptive to learning and understanding the truths of our Catholic faith and to being instructed in virtue.† Casas is outraged because the Spanish policy of â€Å"conversion a nd saving of souls as first priority† was not being followed. Instead, it was being used as an excuse—â€Å"The gulf that yawns between theory and practice has meant that, in fact, the’ local people have been presented with an ultimatum: either they adopt the Christian religion and swear allegiance to the Crown of Castile, or they will find themselves faced with  military action.† He describes how the Spanish would unnecessarily pillage an area, but would essentially be within their legal rights as they would make sure that they presented the natives with the royal ultimatum. Casas’ account is a good reflection of the general imperial policy of expansion of the Spanish Empire. The Spanish Empire used religion as a tool to further its aims—the Spanish Inquisition, for example, was established in 1478 by Catholic Monarchs Ferdinand and Isabella as a way of increasing their political authority via religion and to suppress any tension that may arise from social and cultural differences. While the activities of the colonizers wasn’t the same as the inquisition, as Casas points out, the Spanish in the colonies were using religion in a similar way. Therefore, Casas’A Short Account of the Destruction of the Indies gives important insight into the practices of the Spanish Empire. It also presents an interesting perspective from someone who is a part and within the empire—who is aware and recognizes the malpractices of the Crown and more importantly, is attempting to do something to put a stop to it. It’s also important that the way he goes about this, is through literature—it shows us the importance of the written word in the process of trying to affect a change. Though Casas’ sentiment in the account might not be a common one at the time, it does signal a rising awareness of the moral blindness displayed in the activities of the empires/colonies.

Prevention of Calcium Carbonate Precipitation in Synthetic Formation Waters

A new graduated table inhibitor for bar of Ca carbonate precipitation in man-made formation Waterss Abstraction In this probe, a new repressive chemical composing was developed. The made inhibitor is based on the aqueous solutions of oxiethilidendiphosphone acid, hydrochloric acid, ammonium chloride, polyethylene polyamine-N-methylphosphonic acid and isopropyl intoxicant to forestall the precipitation of Ca carbonate in a long clip operation of the well. The laboratory surveies of new inhibitor showed that the developed inhibitor has a greater suppression efficaciousness and continuance of desorption in comparing with the tried inhibitor SNPH-5312, which is widely used in the Fieldss in Russia to forestall the precipitation of Ca carbonate. The efficiency and corrosion aggressivity of new developed inhibitor were evaluated in three different man-made formation Waterss, which contained assorted ion concentrations and were disposed for precipitation of Ca carbonate. Introduction Huge sums of H2O are injected into the reservoir to keep the reservoir force per unit area at the needed degree, whereby, salt deposition occurs as a consequence of the H2O combination [ 1 ] . As the depletion of the oil field and its transportation to the late phase of development with increasing high H2O cut Wellss, scaling job is aggravated. Besides, there is the demand for backdown residuary oil, necessitating the usage of modern engineerings to better oil recovery, including physical and chemical exposure, which besides stimulates the deposition of salts. The chief grounds of deposition of salts are altering of thermobaric conditions in the procedure of production and the mutual exclusiveness of injected and formation Waterss [ 2 ] . Inorganic salts deposition on the interior surface of oilfield equipment takes topographic point in the procedure of field development of production of moire oil. Salt precipitation occurs in all operation methods of Wellss, but the most negative effects of scaling occur during oil production by electric submergible pumps ( ESPs ) [ 3 ] . Intense deposition of Ca carbonate on impellers ESP is due to the flow temperature addition of produced fluids, which is caused by the heat emanation of runing the submergible motor. Along with salt deposition in Wellss, intense salt precipitation is observed in the wellspring, oil grapevine assemblage, metering devices and installations for the readying of oil and besides in reservoir force per unit area care systems [ 4 ] . The procedure of precipitation of Ca carbonate occurs in three phases. In the first measure, ions of Ca combine with carbonate ions to organize the molecule. Following, molecules combine in microcrystals that serve as crystallisation centres for the reminder of the solution. Crystal aggregates grow and precipitate or attached to the walls of equipment at certain sizes [ 5, 6 ] . Calcium carbonate is found in the signifier of solid white crystals. Factors act uponing the formation of carbonate sedimentations include that formation H2O must be supersaturated with Ca, carbonate or hydrogen carbonate ions [ 7 ] . All control engineering of grading is divided into bar and remotion of scaling. The most effectual method is chemical method of bar by utilizing scale inhibitors. Basic technologies of inhibitor injection are divided as follows: reagent bringing into the wellbore and into the formation. Dose into the well is carried out by agencies of batcher dosing into the ring, into a given point along the capillary and the periodic injection into the ring through collectors. Dose into formation is done through squashing scale inhibitor, injection via injection Wellss ( in force per unit area care system ) , add-on of inhibitor by proppant during fracturing ( ScaleProp ) and injection of the inhibitor with the fracturing fluid during fracturing ( ScaleFrac ) [ 8, 9 ] . The intent of this work is increasing of operational efficiency of bring forthing Wellss by bar of formation of Ca carbonate in the downhole equipment, utilizing the developed inhibiting composing. Methods In the conducted research lab experiments for the readying of chemical solutions was used distilled H2O, in connexion with necessity to extinguish the influence on the belongingss of the composing and the consequences of experiments of ion finding, which were contained in different fresh H2O in assorted concentrations and ratios of their common concentrations. In the readying of look intoing composing harmonizing to the needed volume of the composing and concentrations of constituents, were weighed deliberate sum of H2O and reagents. Medical panpipes and high preciseness research lab balances were used for the exact values aˆâ€ ¹aˆâ€ ¹of the reagents multitudes. Scale inhibitor should be to the full compatible with formation H2O without the precipitation formation while salvaging their belongingss [ 10 ] . For the analysis, man-made solution, the ionic composing of which is near to the composing of formation H2O, is prepared. Inhibitory belongingss mostly depend on the content of Ca in the formation Waterss. Therefore, the compatibility standards can be that if in the readying of the inhibitor solutions in the H2O with a certain content of Ca2+, turbidness is non observed within 24 hours, the inhibitor at a given concentration is considered compatible with the given H2O. The prepared graduated table inhibitor should be more effectual and stable. The effectivity of the inhibitor is evaluated by its consequence on formation H2O or man-made theoretical account of H2O. Using theoretical accounts provides high truth measurings [ 11 ] . Determination of an inhibitor ‘s effectivity is made by appraisal of mass alteration of precipitation, which is formed in mineralized H2O in the presence of inhibitor with regard to H2O with no inhibitor [ 12 ] . Calculation of the protective consequence of an inhibitor is carried out harmonizing to the equation: E % =? 100( 1 ) Where Tocopherol is the scale inhibitor efficiency, m0and m are the multitudes of salt precipitate in the H2O with inhibitor and without inhibitor in gm, severally. The new graduated table inhibitor must hold the low corrosiveness. Corrosiveness of the developed composing is evaluated through the mass decrease of mention samples after their submergence in the inhibitor solution. Corrosion aggressivity of reagents was evaluated by hydrometric method – the weight loss of the samples. The corrosion rate of samples ( denseness of steel samples is 7821 kg.m-3) was calculated from the equation: Voltdegree Celsiuss=( 2 ) Where Vdegree Celsiussis the corrosion rate of the used sample in mm/year, m1and m2are the mass of the metal samples before and after the trial in gm, severally, S is the surface country of samples in m2, t is the trial clip in hr. Scale inhibitors should hold good adsorption-desorption features, heat opposition and minimum toxicity [ 13 ] . Evaluation of surface assimilation and desorption ability of suppressing composing is performed through research lab filtering of suppressing solutions for nucleus samples. Filtration surveies of developed inhibitor on nucleus samples are investigated by utilizing the setup FDES-645 ( Formation Damage Evaluation System ) . Reservoir temperature and force per unit area conditions are applied when utilizing this setup. Result and treatment The consequences of surveies to find the ionic composing of the man-made formation Waterss are shown in table 1. Table 1.

Sulin ‘s system is more descriptive of crude oil formation Waterss than are the other systems [ 14 ] . The entire mineralization of Waterss is located in the scope of 54 – 62 g/l. The theoretical accounts of H2O have the big concentration of hydrogen carbonate, carbonate and Ca ions, which are the chief factor of formation of Ca carbonate salt in the H2O because formation H2O must be supersaturated with thes e ions to precipitate this salt [ 15 ] . The developed composing of inhibitor is evaluated by finding the residuary content of scale inhibitors in samples of liquid. The concentration finding of P of inhibitor in the formation H2O is based on the reaction of phosphate ion with molybdate in acerb medium [ 16 ] . The optical density ( optical denseness ) of the obtained solutions is measured by a exposure tintometer at length ?=540 nanometer in cells with an absorbing bed thickness of 30 millimeter. The optical denseness should non transcend one. Control sample is taken as a standard solution. Each sample is measured on photoelectrocolorimeter two or three times, the arithmetic obtained values are used for the consequence of measuring. From the obtained informations, a standardization curve is plotted by utilizing on the horizontal axis the concentration of inhibitor in mg/l, and on the perpendicular axis the magnitude of its matching optical denseness. As shown in figure 1, the ensuing values of the optical denseness are cor related with the standardization graph and the concentration of inhibitor is found in the trial solution as a consequence of the experiments. Figure 1. The alteration in optical denseness of the solution, depending on the content of the inhibitor in H2O Evaluation of the effectiveness action of graduated table inhibitors by their ability to forestall the salt precipitation were carried out in the liquid solution of man-made formation Waterss. Trials were performed at a temperature of 25 ?C at the exposure clip of 24 hours. The consequences are presented in table 2. Table 2.

The inhibitor figure 1 gives the higher effectivity for bar of Ca carbonate precipitation in all formation Waterss. The difference be tween the inhibitors figure one and two is the alteration in mass fraction of inhibitor constituents. Inhibitor SNPH-5312 is an industrial inhibitor for bar of Ca carbonate formation, which is used in oil field. This inhibitor is based on the composite reagent of P. Table 2 illustrates that SNPH-5312 can protect Ca carbonate formation up to 87 % . Surveies have been conducted to find the compatibility of scale inhibitors with the formation Waterss. All inhibitors were compatible in three man-made formation Waterss, and the consequences showed all the above chemical composing can be prepared in the formation Waterss. The usage of chemical reagents for forestalling the deposition of salts in the Wellss is associated with the usage of chemically aggressive environments. A scale inhibitor is anticorrosion if there is no opposing on the surface of the sample and corrosion rate does non transcend 0.1 mm /year. The caustic activity of above graduated table inhibitors was carried out by hydrometric method by utilizing metal home bases through soaking for 72 hours at 25 ?C. Table 3.

Therefore, these reagents can be considered as reagents to forestall grading in Wellss. The initial concentrations of the reagents in suppressing composings are different, and so it is possible to compare the kineticss of the comparative concentrations of the solutions. The used nucleus samples had mean porousness of 20 % and permeableness of 70 mendeleviums. Figure 2 shows the consequences of finding of the comparative concentrations of the inhibitor reagents in the composings for the surface assimilation procedure at temperature of 120 ?C and force per unit area of 300 standard pressure. Laboratory surveies showed that the confining surface assimilation is achieved when pumping 14 pore volumes for suppressing composings figure 1 and 2, for complete surface assimilation of SNPH-5312, 15 pore volumes must be pumped. By comparing the comparative concentrations of reagents in figure 2 during surface assimilation, it can be concluded that the surface assimilation is faster when utilizing suppressing composings figure 1 and 2. Harmonizing figure 2, more unvarying surface as similation is observed in the composing figure 1. Figure 2. Concentration alterations of the inhibitor solution in the surface assimilation procedure in the nucleus Once the nucleus left for 24 hours to find the surface assimilation equilibrium, formation H2O is pumped into the nucleus to displace suppressing composing. Consequences of finding of the comparative concentrations of inhibitors are shown during the desorption procedure in figure 3. The optimum and recommended concentration of oxiethilidendiphosphone acid in the composing for field conditions, is 10-15 mg/l, it corresponds to the comparative concentration of 0.0001. Harmonizing to figure 2, utilizing the inhibitor SNPH-5312 can supply the needed remotion of the inhibitor, which is sufficient for effectual protection of precipitation of Ca carbonate, when pumping through the nucleus sample of 27 pore volumes of H2O. Effective protection against formation of Ca carbonate under similar conditions persists in pumping 37 pore volumes of H2O when utilizing the developed suppressing composing figure 1, and 32 pore volumes of H2O by composing figure 2. This demonstrates that the developed co mposing have 1.37 times greater continuance of desorption in comparing with the inhibitor SNPH-5312. ( a ) ( B ) Figure 3. Concentration changing of the inhibitor solution in the desorption procedure on the nucleus, ( a ) from 5 to 20 pore volumes, ( B ) from 20 to 40 Data analysis on remotion of considered repressive composings show that a important part of the free inhibitor ( non-adsorbed ) is passed in pumping the first two volumes of pore infinite. The efficiency of the developed composing is explained by the mechanism of influence on the stone acidic additives belonging to its composing. Decisions Inhibitory chemical composing was developed for the bar of deposition of Ca carbonate with an optimum ratio of constituent oxiethilidendiphosphone acid 3 % , ammonium chloride 4 % , polyethylene polyamine-N-methylphosphonic acid 4 % , hydrochloric acid 10 % , isopropyl alcohol 2 % , H2O – balance. The used graduated table inhibitor was evaluated in footings of influence on corrosion actions and it was in the scope of 0.040-0.053 mm/year when the maximal allowable rate is 0.1 mm/year. The new inhibitor was effectual for scale bar of Ca carbonate up to 92 % . The research lab surveies showed that the developed composings have about 1.37 times longer continuance in comparing with the desorption of the tried inhibitor SNPH-5312, which is widely used in the Fieldss for forestalling formation of Ca carbonate.

This paper illustrates that the information revolution has spawned numerous technologies geared towards automating the office. Information systems have created new paradigm shifts in organisational processes. The trend in organisations is to implement office information systems solutions such as groupware and enterprise applications, databases or shared repositories, intranets, workflow, imaging systems, and other customised applications. All these need a specialized skill possessed by business and systems analysts. Internal and external environments in organisations are becoming complicated. These processes and new applications have to be handled by an experienced and specialized workforce composed of analysts who must bewell versed in technology and the business functions. Business analysis encompasses assessments, studies, and analysis of the business functions applied with IT and software applications. Business analysis reconciles the traditional business functions and the techno logy or software so that without it the whole thing will crumble – for example, an organisation conducting outsourcing of human resource has to incorporate the traditional functions with the new personnel who will be handling human resource management. The organisational knowledge and functions have to be ‘transferred’ to the outsourcing company, and this process has to be handled by an analysis team (or an executive team) to analyse the business functions. This is how the business and IT analysts evolved.

The History of Irish Education Part B Essay Example | Topics and Well Written Essays - 1750 words

The History of Irish Education Part B - Essay Example Through years of suppression and political discrimination, politics, in the end, and the shear determination of the Irish to educate their children evolved through concession and necessity into the creation of the National School System--a system destined to provide the basis for public education. Historical Background Originally set up by sects other than the majority Roman Catholics, small schools evolved in the early nineteenth century to educate the poor, manned by teachers most often untrained. Administration of the schools was quickly taken over by the Protestant Church of Ireland as both a religious and political move to Anglicise young Irish students. The Roman Catholic Church, while the majority, and Presbyterians felt pressured by these circumstances and feared a good deal of proselytising was ongoing within in schools. Both the Roman Catholic Church, gaining influential ground in the early nineteenth century after years of social, political and religious suppression, and P resbyterians, viewed as a strong Scottish influence to the Irish brand of Protestantism, had sought as a counter educational measure state support for schools of their own religious tradition. With the Irish Church most influential politically, it was charged that in the small schools of the time children of other denominations were being proselytised by Church of Ireland teachers as part of the educational curriculum. As early as 1812, education commissioners had called for better supervision of proselytizing in schools attended by various denominations, and by 1827 pressure was mounting for the state to cease channeling state aid through ‘voluntary agencies’(Hyland, Milne, 1987, p. 98) most often connected with particular religious groups. The Stanley Letter In October 1831, E.G. Stanley, then Chief Secretary of Ireland, wrote a letter to the Duke of Leinster , a liberal Protestant (Coolahan, 1981, p. 13) outlining plans for proposed national schools guided and overse en by a new sectarian educational board. The letter, now known as the ‘Stanley Letter’, addressed how the government would distribute aid to the board and outlined the basis upon which the board would support the schools. As suggested by Hyland and Milne (1987), the letter is generally accepted as the legal basis for national schools in Ireland, forwarding the recommendation of the Commissioners of 1812 that would effectively ‘banished [banish] even the suspicion of proselytism†¦admitting children of all religious persuasions†¦[and] not interfere with the particular tenets of any’ (Stanley, 1831 in Hyland et al, p. 99). As suggested in the letter (Stanley, 1831 in Hyland et al, p. 99-103) the system was set up as multi-denominational, with the schools governed by a member board consisting of two Roman Catholics, two from the Church of Ireland, and two Presbyterians. The multi-denominational concept at the beginning stages was met with resistance a nd suspicion, particularly by the Catholics and Presbyterians. (Coolahan, 1981) To overcome suspicion and due to Ireland’s history of past religious strife, there were imposed strict limits on the educational component of the proposal. According to Hyland and Milne (1987), during the school day ‘the teacher had to declare that religious education was beginning, hang a sign on

Creating a good system to report medical errors Thesis

Creating a good system to report medical errors - Thesis Example The best solution of the problem is to have comprehensive approach for different aspects of reporting of medical errors and related adverse episodes. The culture of reporting medical errors should be inculcated at all levels including hospitals, clinics, outpatient surgery centers, nursing homes, pharmacies and patients’ home. All the issues associated with reporting should be sorted out. The reporting of medical mistakes can provide invaluable advice to improve medical systems. Building a robust database error reporting system is the step towards delivering quality healthcare. Medical error reporting system should involve both adverse events and close calls nationwide. This will held healthcare providers responsible for any mishap leading to serious injury or even death of the patient. The reporting is automatically going to reduce negligent healthcare errors. This ultimately is going to reflect healthcare system to reach at the highest standard. NYPORTS system of New York de livers information to the state and hospital by identifying, analyzing medical errors and recommends strategies to ameliorate them. IOM has reported that the analysis of errors is very informative. The analysis of deadly mishaps which land up patients to bear life time fatal disabilities might be able to figure out the patterns of system flop. IOM recommends two types of reporting systems: voluntary reporting system and mandatory reporting system. These systems will able to identify potential precursors to errors and it will eventually focus on identifying threats to safety of the patient. The data of the error records should be kept confidential to protect privacy of very individual involved in dealing with particular treatment from patient to healthcare providers. Healthcare providers should be encouraged by their organizations to report committed or observed medical errors during the course of the service to patients. Learning from the mistakes is the

Article Critique Example | Topics and Well Written Essays - 1500 words

Critique - Article Example To be specific, the study concentrates on the girls’ accounts of their enculturation into secrecy. These accounts have pertinent value as they disclose how the girls treated secrets as social objects and often depersonalized secrets when using them as social currency. Merten also points out that â€Å"using secrets to shape friendship and enhance social position was part of the larger process whereby secrecy became a vehicle for developing subjective reason and an exchange perspective among these girls.† (Merten, 1999). The study, therefore, specifically concentrates on relating secrecy with enculturation and the findings have immense value in a deeper understanding of the concept of secrecy. The research is undertaken to develop competencies in evaluating qualitative research; develop analytical skills, the approach is investigative, and the result of the study is that the findings are not logical and satisfactory. The research has been conducted in a suburban community near Chicago at junior high school and interviews with 83 female students and 77 male students provided the data for the study. The purpose of the interviews was to find out the various aspects in the lives of the participant students and the importance of events and relationships in their lives. The observational field notes along with the findings of the interview were used to make the investigation in the study. The relevance of the interviews which were open-ended and informal in style was great in making the ultimate conclusion of the research. The accounts of the girls concerning their experience with secrets in their lives were not the result of a natural dialogue. The accounts by the girls, thoug h were mainly influenced by the peers, could give a complete idea about the various aspects relating to secrecy. Throughout the analysis carried out in the research, the methodology had a pertinent role in the findings of the study. The strategy

Gallery review Essay Example | Topics and Well Written Essays - 250 words - 2

Gallery review - Essay Example The painting is done oil on canvas. The size of the painting is 18 3/8 inches x 21 Â ¾ inches. The overall work is proportionally correct even though the second lady who is sitting is disproportionate in structure. One cannot find out whether she is sitting on a bed sheet or if she has a comforter on her lap. The two ladies are the focal point in the portrait. The work is balanced as the painter as used dark and light colors both. However, It is noticed that the lady who is wearing the black dress has the dark background whereas the second lady is also wearing a dark dress but the background color is light which makes one wonder whether the colors schemes should be less vibrant in order to have a balanced portrait. The color schemes are vibrant. It is a very colorful image. The artist has used warm colors and tried using contrasting colors that make the characters of the painting stand out in the portrait (Gardini). One of the formal characteristics identified in the painting is that the artist has not emphasized on the hair of the two women. One can only tell that the characters are women while looking at the shape of the dresses. Moreover, the expressions of both the women are not intense. While looking at the portrait, it would be difficult to estimate the mood of the women, which should be an essential part of the painting. However, the vibrant colors are the main attraction of the portrait. The main function of the piece is to represent women in vibrant and colorful colors. It shows two women who may be enjoying a leisure time with each other in a garden or a place where there is beauty and they are thinking or talking to each other

Lab report Essay Example | Topics and Well Written Essays - 500 words

Lab report - Essay Example Apart from primary aluminum obtained from bauxite, secondary aluminum and aluminum compounds are obtained through recycling. Recycling aluminum prevents depletion of aluminum ore reserves. Compared with primary production, production of secondary aluminum requires a lower amount of energy. (Davis, 1993) One compound that can be obtained by chemical treatment of used aluminum is potash alum. Potash alum or common alum (potassium aluminum sulfate dodecahydrate, KAl(SO4)2.12H2O) is a double salt. The Al3+ ions in alum act as flocculating agent during water treatment and purification and also as a blood congealer in medicine. (Atkins & de Paula, 2006) To investigate a possible method for recycling used aluminum cans, potash alum was prepared from a piece of aluminum can. Feasibility of the recycling process was studied by calculating the percentage yield. Collecting and weighing aluminum. The aluminum beverage can was washed. A 5Ãâ€"8 cm piece of aluminum was cut from the can. Paint from the outer surface of the can and plastic from the inner surface of the can were scraped off. The aluminum piece was cut into small squares. The aluminum squares were weighed and 0.996 g of aluminum was placed in a 250 mL beaker. Addition of potassium hydroxide. To the aluminum in the beaker, 50 mL of 1.4 M potassium hydroxide was added. The reaction mixture of aluminum and KOH was heated on a hot plate in the hood. Heating was stopped when the mixture turned grey. Vacuum filtering. Vacuum filtration apparatus was set up. The hot solution was vacuum filtered. The beaker used was rinsed with distilled water (5 mL) and this solution was also vacuum filtered. The filtrate obtained was cooled in an ice-water bath for a few minutes. Addition of sulfuric acid and crystallization of alum. To the cooled filtrate, 20 mL of 9.0 M sulfuric

Gmf (Genetically Modified Food) Essay Example for Free

Gmf (Genetically Modified Food) Essay Genetically modified foods is the term most commonly used to refer to crop plants created for human or ani mal consumption, which have been modified in the laboratory to enhance desired traits or improved nutritional content. The enhancement of desired traits has traditionally been undertaken through breeding, but conventional plant breeding methods can be very time consuming and are often not very accurate. Genetic engineering, on the other hand, can create plants with the exact desired trait very rapidly and with great accuracy. Development. GM foods were first put on the market in the early 1990s. Typically, genetically modified foods are plant products: soybean, corn, canola, and cotton seed oil, but animal products have been proposed. The first commercially grown genetically modified whole food crop was the tomato puree (called FlavrSavr), which was made more resistant to rotting by Californian company Calgene. Currently, th ere are a number of foods of which a genetically modified version exists. What plants are involved? Some foods have been modified to make them resistant to insects and viruses and more able to tolerate herbicides. Crops that have been modified for these purposes, with approval from the relevant authorities, in a number of countries, include: maize, soybean, oilseed rape (canola), chicory, squash, potato. Some of the advantages of GM foods: There is a need to produce inexpensive, safe and nutritious foods to help feed the world’s growing population. Genetic modification may provide: ï‚ · Better quality food. ï‚ · Higher nutritional yields. ï‚ · Inexpensive and nutritious food, like carrots with more antioxidants. ï‚ · Foods with a greater shelf life, like tomatoes that taste better and last longer. ï‚ · Food with medicinal benefits, such as edible vaccines for example, bananas with bacterial or rotavirus antigens. ï‚ · Crops and produce that require less chemical application, such as herbicide resistant canola. Some of the disadvantages of GM foods: Food regulatory authorities require that GM foods receive individual pre-market safety assessments. Also, the principle of ‘substantial equivalence’ is used. This means that an existing food is compared with its genetically modified coun terpart to find any differences between the existing food and the new product. The assessment investigates: ï‚ · Toxicity (using similar methods to those used for conventional foods). ï‚ · Tendency to provoke any allergic reaction. ï‚ · Stability of the inserted gene. ï‚ · Whether there is any nutritional deficit or change in the GM food. ï‚ · Any other unintended effects of the gene insertion. Economic concerns: Bringing a GM food to market is a lengthy and costly process, and of course agri -biotech companies wish to ensure a profitable return on their investment. Many new plant genetic engineering technologies and GM plants have been patented, and patent infringement is a big concern of agribusiness. Yet consumer advocates are worried that patenting these new plant varieties will raise the price of seeds so high that small farmers and third world countries will not be able to afford seeds for GM crops, thus widening the gap between the wealthy and the poor. One way to combat possible patent infringement is to introduce a suici de gene into GM plants. These plants would be viable for only one growing season and would produce sterile seeds that do not germinate. Farmers would need to buy a fresh supply of seeds each year. However, this would be financially disastrous for farmers in third world countries who cannot afford to buy seed each year and traditionally set aside a portion of their harvest to plant in the next growing season. How are GM foods labeled? Labeling of GM foods and food products is also a contentious issue. On th e whole, agribusiness industries believe that labeling should be voluntary and influenced by the demands of the free market. If consumers show preference for labeled foods over non -labeled foods, then industry will have the incentive to regulate itself or risk alienating the customer. There are many questions that must be answered if labeling of GM foods becomes mandatory such as; are consumers willing to absorb the cost of such an initiative? If the food production industry is required to label GM foods, factories will need to construct two separate processing streams and monitor the production lines accordingly. Farmers must be able to keep GM crops and non -GM crops from mixing during planting, harvesting and shipping. It is almost assured that industry will pass along these additional costs to consumers in the form of higher prices. Food labels must be designed to clearly convey accurate information about the product in simple language that everyone can understand. Conclusion: Genetically-modified foods have the potential to solve many of the worlds hunger and malnutrition problems, and to help protect and preserve the environment by increasing yield and reducing reliance upon chemical pesticides and herbicides. However, we must proceed with caution to avoid causing unintended harm to human health and the environment as a result of our enthusiasm for this powerful technology.
