fetal pain essays

fetal pain essays Fetal and Neonatal Pain and Long Term Implications Over the last decade, the perception of pain and stress in fetal and neonatal life has attracted great attention. This is partly due to an increasing understanding of fetal physiology and a greater number of invasive techniques used in todays medicine. The greater frequency of abortions, caesarean sections and intra uterine interventions have turned increased attention onto the subject after decades of common belief being that the fetus and neonate felt no pain. The most important evidence is anatomical. This shows that the neuroanatomical connections for nociception are in place by the 24th week of gestation. Many experts however believe that the fetus only experiences mindless reflex responses which are a mechanism of protection for an adapting organism that has not yet developed a mature sensory and effector system. There is evidence present to suggest that a single painful experience can alter development and sensitisation of the infant to pain and stress later in life. In the following essay I am going to review the evidence supporting the long term effects of painful and stressful experiences suffered by fetuses and the newborn. I will also assess whether there is a period of increased sensitivity to injury and analyse studies focusing on the use of analgesia to avoid these long term implications. There is a large amount of evidence showing that stressful events both during and just after pregnancy can influence the developing fetus and bring about a series of long term adverse effects in the infant. Recent evidence however has been conflicting and inconsistent. Research and investigation in this field is difficult however for a number of reasons. One of these reasons is that pain is not objective, but subjective. It is difficult to assess and measure pain in adults who can communicate and express their feelings. In a fetus the absence of feedback is a...

Collective Nouns and Verb Agreement in Spanish

Collective Nouns and Verb Agreement in Spanish Collective nouns - singular nouns that refer to more than one being or thing - arent consistently treated as either singular or plural in Spanish. Grammar Rules for Using Collective Nouns There is one grammar rule, however, that is clear: When the collective noun  is followed immediately by a verb, the noun is treated as singular. La gente cree que las cosas estn mal. (People believe things are bad).La muchedumbre fue manipulada. (The crowd was manipulated.)Sobre el papel, el equipo era muy competitivo. (On paper, the team was very competitive.) However, when there are words that intervene - especially de followed by a plural noun - Spanish speakers are inconsistent in the verbs they use. Authorities also disagree on which choice of verb is proper. Note the following examples, all found  through a search of mainstream Spanish-language web pages: Somos un grupo de personas que conforma la lista de correo electrà ³nico. (We are a group of people who belong to an email list.)Somos un grupo de personas que deseamos compartir con ustedes. (We are a group of people who wish to share with you.)Un rebaà ±o de nubes negras pasea por el cielo. (A group of dark clouds marches across the sky.)El rebaà ±o de hembras deben integrarse en el de los machos. (The herd of females ought to blend with one of males.)Cerca de la mitad de las personas en edad de jubilacià ³n en el mundo no reciben ningà ºn tipo de pensià ³n. (About half of the worlds people of retirement age will not receive any kind of pension.)La mitad de las empresas espaà ±olas realizar on line el 20 por ciento de sus transacciones. (Half of Spanish businesses will carry out 20 percent of their transactions online.)Una docena de chicos se alimenta en el basural. (A dozen children are feeding themselves in the dump.)Una docena de entidades crean una plataforma para impuls ar el laicismo. (A dozen entities are creating a platform to promote expanded use of the laity.) There are some authorities who indicate that the choice of singular or plural verb depends on whether it refers more to the group or to the individual entities that make up the group. But as you can see from the examples above, in real speech no such distinction is made.

Preventing Nuclear Capacities in North Korean or Iran Essay

Preventing Nuclear Capacities in North Korean or Iran - Essay Example The United States can possibly employ the use of economic pressure to try and force North Korea to return t the six-party negotiations that also include South Korea, Russia, Japan and China. These talks were originally designed to try and help in the establishment of a peaceful resolution to security concerns that happen to result from the nuclear weapons program that had been conducted by North Korea. The United States can endeavor to utilize these talks to try and convince North Korea to abandon its nuclear weapons program (Cronin, 273).1 The presence of nuclear weapons in the hands of North Korea is of relatively great concern to the United States. If the Six-party negotiations continue to be ineffective, the United States will potentially find itself quite unable to effectively address the concerns posed by nuclear capabilities in North Korea unless it engages directly with the country. A possible concession that can be made is that the United States can pledge that it will not attack North Korea if it willingly shuts down its plutonium program. Other options can involve the withdrawal of American troops from the Korean Peninsula in return for North Korea ending its uranium enrichment program (Cronin, 273).2 If all options fail, and the security of the country remains in critical danger, I would order the complete elimination of the considerable nuclear threat currently being posed by North Korea. A surgical and very speedy attack on the various nuclear weapons development sites across North Korea will have the effect of completely destroying North Korea’s ability to make nuclear bomb. It might also have the effect of precipitating the downfall of the oppressive regime of Kim-Jong-II in addition to sending a an emphatic and clear message that the United States will in no way accept any nuclear proliferation that poses as a threat to it (Ochmanek and Schwartz,

Global Perspectives on Health Essay Example | Topics and Well Written Essays - 750 words

Global Perspectives on Health - Essay Example While aspects such as GDP growth, Infant Mortality Rate and Adult Literacy Rate, Tanzania records a relatively higher statistic in comparison to the whole of the average in the African Region. Nevertheless, when we look at the statistics in a global perspective, it can be concluded that the numbers for Tanzania is staggering. Total Fertility Rate, Under 5 Mortality Rate and Life Expectancy at Birth are just some of the health indicators which show how the country is struggling in indispensable area of health care. The graphs show that there is little to no progression in terms of Life Expectancy at Birth, Infant Mortality Rate, Under 5 Mortality Rate and Total Fertility Rate of Tanzania. It can be observed that Infant and Under 5 Mortality Rates gradually decreased in more recent years. Life expectancy was also augmented while Fertility Rate remained more or less at the same level. This increase in statistics is a good signifier of a move in progress in terms of health. Based on the data shown, it can be perceived that Tanzania has a reasonably high population rate wherein the number of male population is almost similar with the number of female population. It also illustrates that majority of this population are aged 20 and below. This can be directly related to the mortality and life expectancy rate of the country. The World Health Organization attributes the low level of health in the United Republic of Tanzania primarily to poor nutrition, illiteracy and gender inequality. HIV remains to be the most prevalent problem in the country’s communicable DALY but some progress is being shown. From 9.9% as reported in 2000, HIV infection slowed down to 7% within the years 2003-2004 (World Health

The Atlantic Slave Trade Essay Example for Free

The Atlantic Slave Trade Essay The Atlantic Slave Trade had a both positive and negative impact on those involved in it to an extent. Britain’s economy benefited greatly from the slave trade as many industries flourished. This was an immense opportunity for those who were unemployed as it provided thousands of jobs. People were employed in industries like the building and repair of slave ships, selling the goods produced by slaves such as sugar and cotton, and banking. This resulted in the slave trade becoming the financial base of development of Britain. However, not everyone benefited from this trade as it had an enormous negative impact on Africa’s society and economy. The 37 years of slave capturing and exporting resulted in wars between tribes and drained Africa’s population of 12 million of its strongest youth. This resulted in Africa’s economic development in being hindered. For Africans the physical experience of slavery was painful, traumatic and long-lasting. Britain benefited from the slave trade in many ways including the economy, as slavery became part of the financial base of development in Britain. Many economic factors contributed to slavery including the demands of plantation farming, servant slaves and the growth of the slave trade as its own industry. Plantation farming emerged as a way to earn a profitable crop and dominated the southern colonies. In plantations African slaves worked in hundreds from dawn until dusk producing goods that supplied Britain. These goods consisted of sugar, cotton, tobacco and rum. All these crops were very labour intensive requiring hundreds of workers to preserve them. The British became the largest and most efficient carriers of slaves to the new world. Therefore huge profits were made by the labour of unpaid slaves. Liverpool and Bristol were the main trading ports in Britain, Liverpool alone made  £300,000 per year from the slave trade. Scotland was also heavily involved in the slave trade, Scots went out to colonies and generated great wealth for Scotland based on slave labour. Glasgow’s â€Å"Tobacco Lords† profited from the slave trade, as did the merchants of London, Liverpool and Bristol. The city of London catered the economic services that were necessary for the slave trade, this included insurance and loans for slave traders. F.G Kay wrote about the social changes that happened in Britain following the growth of the slave trade, in a book named â€Å"The Shameful Trade† published in 1967. He states â€Å"the slave trade created a new class of wealthy colonial  families†. Bristol merchants who were great dealers increased their trade with the islands of the Caribbean. They also became specialists in trading with West Africa and retailing captured slaves. The trade also created, sustained and relied on a large support of shipping services, ports and finance companies employing tho usands of ordinary people. Many slave ships were need and thousands of jobs were created through this. Jobs in making slave ships, repairing, financing and insuring all flourished. By 1780 Liverpool had become the largest slave-ship building site in Britain. This also provided thousands of sailors with work. . Insurance was one of the biggest industries during the slave trade, insurance and long term loans created new opportunities for making more money. Slave merchants and sugar plantation owners needed to borrow money to keep their businesses going. Merchants involved in the triangular trade found that insurance was vital because if their ship hit a storm during the voyage its cargo could be lost, and if that ship is not insured then they could lose everything. There were huge profits in selling the goods produced by slaves such as cotton, sugar and tobacco. Thousands of people were employed in factories to make exportable goods that were traded in for slaves in Africa these were guns, textiles and pottery. People were also employed in making brass and copper in Yorkshire, weavers in Birmingham, chain makers and sugar refiners in Greenock. The slave trade made Britain the world’s leading sea power and it helped finance the indus trial revolution. The British government made a fortune from the taxes related to the slave trade. Nonetheless not everyone profited from the slave trade, The Atlantic Slave Trade had enormous negative effects on the continent of Africa. Many parts of Africa suffered from an increase in violence, drain of people and an economy increasingly reliant on slavery. As a result of this Africa fell behind the rest of the world. Having fewer young healthy people to produce food would make famine more likely and the rates of death worse. Slavery led to the movement of thousands of people across Africa, allowing disease to spread between different parts of Africa. A lot of good land was left uncultivated and not looked after because there were not enough young people left to farm it. African slaves took with them their religion, traditions, cooking, clothes, music and dance. These had a negative impact on Americans  as it led to voodoo in the West Indies. The slave trade encouraged conflicts between African tribes, raids and kidnapping. The demand for more slaves led to increased hatred and violence between communities in Africa. There was also the spread of racist ideology to justify the enslavement of Africans. It is estimated that up to 12 million Africans were snatched from their homeland shipped to the Caribbean to work on plantations. Thousands of African villages were ruined as they were raided for slaves. The farming in Africa changed to grow crops which were brought to supply slave ships. African chiefs and kings stopped ruling by law as they became greedy cunning tradesmen. The 37 years of slave capturing and exporting drained Africa of millions of its strongest youth. As a result of this the population became unbalanced and the adult male population was reduced to 20%. Overall Africa was the only continent to be affected in this way, and because of the loss in population it became a major factor leading to its economic hardship. John Newton was a British slave trader in West Africa. In a small extract from his journal he comments on the immoral methods used between Africans and Europeans, he states â€Å"Europeans try to cheat Africans at every turn. Any article of trade that can be cheapened is so. Spirits are diluted with water, kegs of gunpowder have false bottoms and pieces are cut out of rolls of cloth†. In conclusion it is clear that Britain benefited from the Atlantic Slave Trade. We know this because of how it boosted the British economy as many industries grew, created thousands of jobs and supplied Britain with essential everyday life goods. We also know that colonies were established on the backs of hard-working African slaves. However not everyone benefited from the slave trade as it made Africa suffer greatly. Up to 12 million young strong Africans were forced out of their homelands and brought to the Caribbean to work without pay. Families separated and sold to go and work on plantations from dawn until dusk. Thousands of villages were wrecked because of the raiding for slaves. African leaders became dishonest, deceptive greedy tradesmen which resulted in Africa becoming corrupt.

Epidemiology and Treatment of Bovine Spongiform Encephalopathy Essay

The Epidemiology and Treatment of Bovine Spongiform Encephalopathy (BSE) Bovine Spongiform encephalopathy (BSE) is a serious disease found mainly in the U.K. that effects cows and humans alike. Humans can get the new variant Creutzfeldt-Jakob disease by eating beef contaminated with BSE. The exact cause of BSE has yet to be discovered, but there are many theories that suggest that the infectious agent of scrapie and mutated prions have something to do with it. Bovine Spongiform Encephalopathy, more commonly known as Mad Cow Disease, is a Transmissible Spongiform Encephalopathy (TSE). A TSE is a progressive disease believed to be caused by the folding (mutating) of prion proteins found in the brain and causing brain deterioration. Other forms of TSEs are scrapie, Kuru and Creutzfeldt-Jakob disease. TSEs are contracted either sporadically or by inheritance. In order for an animal or human to contract a TSE sporadically, they must not have had the mutant prion protein allele in their body prior to an infection of the said protein. When the prion enters the body, it causes a chain re...

Japanese Culture and Politics Essay

The historical development of Shinto cannot be separated from the entire history of Japanese religion, culture and politics holding the Japanese mentality to the path of creative progress and versatility of self-development. From the fate of the Emperor’s courts in different eras, with the rise and fall of other religious orders such as the Buddhist groups and the overall destiny of the nation, the fate of Shinto is intertwined in every aspect. Shinto had already started to about 300 B. C. E. and was considered as the most significant religion in Japan. In reality, there is no specific dates nor enough data or hard evidence of Shinto’s origins, as such, it may trace back even before the 300 B. C. E. Just like Shinto’s origins, the origins of civilization on the Japanese islands remain cloudy. Various communities gathered together during the Stone Age. As early as the 300s and 200s B. C. E. , tightly knit societies were appearing, but the mountainous terrain of the home islands kept settlements relatively isolated. Although Shinto tradition traces the ancestry of the Japanese imperial family back to the 600s B. C. E., there is no evidence of an organized Japanese government before the 300s or 400s C. E. Body The history of Shinto is connected to the development of growth of states. The first imperial state was ruled by the Yamato family, starting in the 300s or 400s C. E. From the start, the Shinto religion- which remained important even after the arrival of new faiths like Buddhism- legitimated the emperors, declaring them descendants of the sun goddess. The Yamato initially ruled from Nara, which, until the late 700s, serves as Japan’s capital. During the Nara period (ca. 300-794 C. E. ), the foundations of the Japanese nation were laid. Japan also came into contact with Korea and China. The Chinese had a tremendous influence on the development of Japanese art, architecture, literature and religion. It was from China and through Korea that, in 522 Buddhism arrived in Japan (McCannon 2006). However, Shinto was already greatly present in early Japan, as such, they were able to develop their own state different from that of China Shinto has been considered to be the creative spirit, and on the contrary, as a firmly fixed source of nationalism in Japan. Although the roles need not be incompatible, the question draws attention to two faces of Shinto. There are folk origins as well as cults encouraged by governments, and these have not always coexisted harmoniously. During the development of State Shinto, the conflict and peace reaches its peak. The Meiji period government, in the interests of manipulating Shinto as a state ideology, was prepared to sacrifice the entire popular spirituality of Shinto to the extent of suppressing shrines and removing kami from communities. This underlines the dual origins of Shinto and the ways in which local and national interests have not always been harmonized. The august status of the Grand Shrines of Ise, the Amaterasu greatly shows how Shinto had affected the people’s respect towards the Imperial tradition (Picken, 1994). Shinto religion became the core of some social classes and basis for economy, traditions and customs. During the time when sengoku daimyo and the three great unifiers were struggling for political supremacy, they adopted and utilized various methods with varying degrees of success to overcome basic administrative difficulties. Sengoku daimyo and the national hegemons encountered difficulty in bringing the commercial segments of the society under their control. The existence of a growing national market in central Japan where most of the large scale transactions involving goods from the distant provinces were conducted in the sixteenth century and which remained relatively free of any political control during much of that century, did not permit the sengoku daimyo and the national hegemons to regulate the growing commercial activities to their advantages (Hall et. al. 1983). Through Shinto, the society was divided into classes, where many sengoku daimyo introduced the system of rule by law to strengthen their authority in their respective domains. Also, by focusing on Shinto religion, sengoku daimyo was able to have the absolute loyalty of its subordinates, discouraging localized or scattered loyalties. Moreover, early believers of Shinto greatly respected animals. They believed that these are God’s messengers and because of these, the early Japanese created statues such as â€Å"Koma-inu† on their temple grounds. Japanese culture also flourished with ceremonies correlated to the practice of Shinto and some of these include cleansing, prayers and dances greatly attributed to Kami. In addition to this, they also practiced Kagura, a dance perfected by its performers with an accompaniment of ancient musical instruments (Robinson 1995). Conclusion The historical development of Shinto cannot be separated from the entire history of Japanese religion, culture and politics holding the Japanese mentality to the path of creative progress and versatility of self-development. From the development or origins of Shinto, the states of early Japanese period came into realization. State Shinto is one of the great examples of the states created using Shinto as its foundation. Aside from its states, the rulers of state before the Tokugawa period were chosen with the blessings of the gods of Shinto. The divine providence given to these rulers strengthened their power over their subordinates. Just like the power of the sengoku daimyo during the Warring period. They were able to obtain absolute loyalty from their subordinates and the other classes. Shinto did not only create Japan’s early states and leaders, but also molded its culture, customs and traditions. Early beliefs on Shinto gave life to the Japanese society, illuminating it with dances and ceremonies. As a whole, early Japanese culture and politics developed its own identity becoming one of the countries with great sense of nationalism because of Shinto.

Eugenics: the Artificial Selection

S R August 26, 2008 Biology 340 Eugenics: The Artificial Selection In the 1800’s, well-known biologist, Charles Darwin enlightened us with his theory of evolution and natural selection. In short, natural selection states that random genetic changes transpire within an organism's genetic code, such changes are preserved because they are valuable for survival. Darwin’s ideas came from economics applied to biology. By the late 1800’s Francis Galton, Darwin’s cousin, had thoroughly studied his cousins findings and disclosed his beliefs in biology, which he related to human beings.His philosophy was known as Eugenics. Eugenics was an idea was based on ways to control reproduction so that human race can better succeed, in other words, a revised sequel of Darwin’s natural selection, artificial selection. Galton understood that good advancement of mankind was let down by generous outreach to the underprivileged when such hard work motivated people to have m ore children. Galton sought after expanding his eugenics idealism from science to a policy and religion. This science was a form of perfecting the human race through improved reproduction.That alone should have scared people, however, it began to evolve, as Galton desired. Eugenicist aspired the development of advantageous characteristics and abolition of the adverse ones. Eugenics was seen as a means to resolve the combined problems because it located the cause in the flawed germ cells within the embryo of individuals of certain ethnic groups instead of focusing on the structure of society. Eugenicist alleged that inherited disorders with basic modes of inheritance could be construed from derivations of inheritance contained by families, such as polydactyl.Psychiatric disorders, such as manic depression, were also considered when researching inherited disorders. Geneticist understood that behavioral personality had the utmost impact on society. They assumed that people inherited a trait that made them have an affinity to be poor. This was termed as shiftlessness. Other predispositions that were deemed inherited were alcoholism and sexual immorality, which was a notion to be part of the cause to criminal behavior.In the 1920’s restrictive immigration laws were passed because eugenicist believed that undesirable traits were linked to racial and ethnic groups, which was detrimental to society. Furthermore, eugenics was incorporate by Adolf Hitler’s attempt at a master race. His barbaric behavior and massacre of Jews made the initiative of developing a master race became exceedingly ostracized. However, eugenics should not be considered eradicated from society. Some believe that the advancement and encouragement of birth control is considered a major eugenic success.It was seen as a eugenic success because of a sudden increase in population and frenzy to control this. I understand that eugenics may be intended to promote reproduction among the genet ically advantaged. Therefore, in that sense I find it to be acceptable to some extent. The practices that follow this type of positive eugenics, nowadays, is slowly being accepted in society. Such as, in vitro fertilization, a couple may find this option as a gift in life. However, others may argue that adoption is always the best option when infertility is an issue.The fact that there are millions of children that do not have parents, would make me opt for child adoption. As previously mentioned, birth control is considered a eugenic success. In this area I would agree with that generalization. I find that women should take care of themselves form of eugenics that I consider eugenics negative when the attempt is to subordinate fertility amongst the genetically underprivileged. Such an example would be to have an abortion knowing that your child will have a disability.Overall, this subject matter is more complicated and thought provoking that it may seem when once introduced. Howeve r, the evolution of society has made modifications to the early eugenic standards.Work Cited EugenicsArchive. org Image Archive on the American Eugenics Movement http://www. eugenicsarchive. org/eugenics/list3. pl Adams, Mark, ed.

The Case of the Elusive Car Salesman Essays - Sedans, Sports Sedans

The Case of the Elusive Car Salesman Essays - Sedans, Sports Sedans The Case of the Elusive Car Salesman Subject: English Short Story The Case of the Elusive Car Salesman I was pacing around Lexington, waiting for my local mechanic to finish the latest repairs on my 77 Chevy Impala. My name's Yesterday, Sam Yesterday. It was hot in Lexington, by that is not uncommon for mid-July. I'd had a good several months, and I was in good financial position for the first time since I bought that Impala back in 1977. That car had served me well, but lately it had been failing. Maybe it was time for a trade, I thought; so I walked over to the nearest friendly (sort of) car dealership. As soon as I set foot on the shiny showroom floor, it seized me. It was the most beautiful thing I had ever seen. A sparkling combination of steel, leather, electronics, and a very large engine. The muscle car had been revitalized in the form of a 1995 Chevy Impala SS. It was sleek, resembling the type of car Darth Vader would drive. I grabbed the nearest salesman, hopped into the body hugging leather bucket, fired up the 275 bhp. LT1 engine and took off. As the 6-speaker CD stereo belted out Aerosmith the poor salesman tried to sell me a car that had already sold itself. I had fallen in love, it was the only car that I had loved since that 77 Impala. It had an engine large enough to satisfy my primitive need for power, an image that screamed "Hey you with the radar gun! See if you can catch me!" Granted, it was heavy, it had watery boat-like handling, and drank gas like my Uncle Bubba drinks beer. Still, I loved it. It wasn't Japanese, German, Korean, or otherwise. It was a big hunk of purebred, American muscle car, dammit. I picked out a nice shiny new one, called the bank and drove home in my new wheels. I decided to spring for all the bells and whistles; leather, CD player, alarm system, keyless entry, etc. I figured that if this car was going to run as long as my last Impala it should be well-equipped. As I was admiring the view from my office in the Financial Center, the phone rang. I answered and was greeted by a rather hysterical woman named Diane who thought that she had been cheated by her car dealership. "That evil Car salesman has kidnaped my car!" she explained. I calmed her down and asked what happened. "Well, Larry, the salesman, picked up my Lexus for servicing, just as usual. Also as usual, he left a more expensive car as a loaner. Later in the day, I received a call saying that my car had been destroyed. Larry said that one of the technicians had accidentally cranked it right up into the ceiling while it was sitting on the lift. I found it hard to believe, but he promised me a new model if I would just come over and sign the papers. As soon as I arrived, Larry said that he would credit me the value of the car if I wanted to by a nicer mor expensive model. I agreed and ended up with a lovely new sports coupe." "Nice car," I remarked, realizing that the salesman was making a tidy profit on the transaction. "Yes, it is. But I still miss my Essie." "Essie?" I interrupted, quizzically. "Yes, Essie was the name of my old car, the ES300, I loved Essie, and the new car wasn't the same." "You had a brand new $55,000 Lexus, which you got for only $25,00 and you miss you older $35,000 Lexus?" I asked, beginning to wonder whether she was playing this game with a full deck. "Yes, I did. So, anyway, I read the article in the paper covering the incident, and was struck by something. The general manager said that he was baffled, because there are safety mechanisms on the lifts, preventing them from going that high. I also realized that Larry would be making his regular commission on a $55,000 Lexus, and not a $25,000 one, because the payment for the ES was made by the insurance company after the sale. So, not only had he made money on Essie, but on the new car as well." "Interesting. Is that all?" I asked. "Yes. If the accident wasn't really an accident, I want to know, and I want a lot more than a new sports coupe, that car meant a lot to me." She concluded,

The Boiling Point of Alcohol

The Boiling Point of Alcohol The boiling point of alcohol depends on which type of alcohol youre using, as well as the atmospheric pressure. The boiling point decreases as atmospheric pressure decreases, so it will be slightly lower unless you are at sea level. Here is a look at the boiling point of different types of alcohol. The boiling point of ethanol or grain alcohol (C2H5OH) at atmospheric pressure (14.7 psia, 1 bar absolute) is 173.1 F (78.37 C). Methanol (methyl alcohol, wood alcohol): 66 °C or 151 °FIsopropyl Alcohol (isopropanol): 80.3 °C or 177 °F Implications of Different Boiling Points One practical application of the different boiling points of alcohols and of alcohol with respect to water and other liquids is that it can be used to separate them using distillation. In the process of distillation, a liquid is carefully heated so more volatile compounds boil away. They may be collected, as a method of distilling alcohol, or the method may be used to purify the original liquid by removing compounds with a lower boiling point. Different types of alcohol have different boiling points, so this can be used to separate them from each other and from other organic compounds. Distillation may also be used to separate alcohol and water. The boiling point of water is 212 F or 100 C, which is higher than that of alcohol. However, distillation cant be used to fully separate the two chemicals. The Myth About Cooking Alcohol out of Food Many people believe alcohol added during the cooking process boils away, adding flavor without retaining alcohol. While it makes sense cooking food above 173 F or  78 C would drive off the alcohol and leave the water, scientists at the University of Idaho Department of Agriculture  have measured the amount of alcohol remaining in foods and found most cooking methods dont actually affect the alcohol content as much as you might think. The highest amount of alcohol remains when alcohol is added to boiling liquid and then removed from heat. About 85 percent of the alcohol remained.Flaming the liquid to burn off the alcohol still allowed for 75 percent retention.Storing food containing alcohol overnight with no heat applied resulted in 70 percent retention. Here, the loss of alcohol occurred because it has a higher vapor pressure than water, so some of it evaporated.Baking a recipe containing alcohol resulted in alcohol retention ranging from 25  percent (1 hour baking time) to 45 percent (25 minutes, no stirring). A recipe had to be baked 2 hours or longer to bring the alcohol content down to 10  percent or lower. Why cant you cook the  alcohol out of food? The reason is that alcohol and water bind to each other, forming an azeotrope. The components of the mixture cant be easily separated using heat. This is also why distillation isnt sufficient to get 100  percent or absolute alcohol. The only way to completely remove alcohol from a liquid is to boil it away completely or allow it to evaporate until its dry.

Quotes from Ludwig Wittgenstein (The book, Tractatus Essay

Quotes from Ludwig Wittgenstein (The book, Tractatus Logico-Philosophicus) - Essay Example in determining meaning arrives through the process of determination of whether an elementary proposition can be considered true or false depending on how it relates to the perceived reality of the world that is accepted as real by the multitudes. Language can therefore be said to consist entirely of propositions all of which can be analyzed for the purpose of breaking them down into elementary propositions. In turn, elementary propositions are actually simply name combinations used to refer to objects. On the metaphysical level, elementary propositions can also be termed logical representations of atomic facts. It is at the level of atomic facts that metaphysical language becomes particularly confusing because atomic facts are combination of complex facts that represent truth in the world (3.261) If language is a series of elemental propositions representing logical representations of atomic facts, then the obvious answer to the question of metaphysical meaning lies in the realization that any meaning of a particular word must be divorced from the thing it is intended to represent and instead pulled forth from this distortion of meaning so that it is applied instead to how the word is utilized. The meaning of language essentially becomes intertwined with context constructed from the elementary proposition. If elementary propositions are intended as a logical representation of an atomic fact then it becomes true that facts can change through context. As an example, consider the blue heron in scenario one. The blue heron can be broken down into several elementary propositions and the one the participant chooses to use in the scenario becomes a logical representation of the atomic fact that represents only the truth that some people do seen signs and make connection. Essentially this entire scenario can be read as a language game in which words like â€Å"sign† â€Å"soul† and â€Å"being† are all capable of being used with a broad amount of variability. Due the
