Dealing with disaster - Essay Example The cavalry he referred to includes many rescue personnel and organisations. Many individuals, groups, and agencies get involved in disaster response and recovery operations. It is important for disaster response planners to understand these teams in order to assign them roles and responsibilities that they can fulfill effectively during a disaster. The United Kingdom is less susceptible to large-scale disasters than many other countries. However, the UK is not entirely immune from the effects of all hazards. According to the national risk assessment, UK is considered to be most at risk from the spread of pandemic diseases, the effects of severe weather and flooding (Caron, Kelly, and Telesetsky 2013: 81). As a result, the UK government has established its domestic disaster response framework at all levels in the central government and local authorities. Different organisations including the civil society organisations and other institutions such as the British Red Cross Society get involved in disaster response, and their roles and responsibilities are outlined in this framework. This framework is highly devolved, and it may be difficult to establish what qualifies to be a well-defined role or responsibility and what does not. However, Caron, Kelly, and Telesetsky (2013) proposed that the emergency response framework should pr ovide greater clarity and understanding for all response teams. The rate at which disasters occur has risen from about 200 disasters in the 1980s to about 400 disasters per year (United Nations 2008: 1). 0ver 90 percent of these disasters are climate-related, and it is projected that this trend will continue as the weather related hazard events will continue to be more volatile and more frequent. The vulnerability is growing, and countries have become more prone to disasters. This vulnerability has increased due to

The history and perceptions of the secession crisis Research Paper

The history and perceptions of the secession crisis - Research Paper Example The conflict between Northern and Southern politicians was brought about by the massive western territories acquired by the United States in 1848 through the peace agreement with Mexico (Bartkus 1999).Southerners petitioned for the freedom to bring slavery into the newly acquired territories if the circumstances allowed lucrative ventures; Northerners demanded slavery clearly and completely abolished (Reynolds 1970). As stated by Huston (2000), the dispute had been raised by David Wilmot in 1846, yet it only reached an agreement in 1850 when the different sections of the Compromise of 1850 were ratified in Congress. Following the congressional resolution is the electoral affirmation that this agreement was definitely amenable (Crofts 1989). The congressional elections in the 1850 spurred Democratic wins of the compromise procedures in the North, which were eventually clearly reconfirmed in the 1852 presidential election (Wakelyn 1996). The reaction of the South to the Compromise was dissimilar. States in the upper South, namely, Delaware, Missouri, Maryland, Arkansas, Tennessee, Virginia, Kentucky, and North Carolina, willingly agreed to the actions taken by Congress; however, states in the lower South, namely, Mississippi, Alabama, Georgia, and South Carolina initiated a large-scale controversy about secession (Barnwell 1982). In 1850, particularly in the gubernatorial and congressional elections as well as in state conventions, the Southern states that agreed to the Compromise of 1850 largely succeed ... rther, according to Huston (2000), for a number of historians, the major concern, and hence the core of their interest, was the secession debate, not the debate over union, and the common assumption has been that the cotton-dependent Southerners refuted secession as a remedy to the suspected Northern incursions on the constitutional rights of the South. Few recognize the attempt of Southern unionists to mitigate the secession conflict in 1850 (Wakelyn 1996). The Southern States Rights, those supporting either provisional or immediate secession, have gained most of the attention. The victors of the elections in the state of the Deep South, the Constitutional Unionists or the unionists, have been given very little emphasis (Wakelyn 1996). It is not occasionally claimed, specifically by scholars of the nineteenth century, that the winners did not only enjoy the rewards, they also gained much of the historians’ interest (Barnwell 1982), and history is thus presented from the stand point of the victors. Basically, fury over the compromise stemmed mostly from Mississippi, Alabama, Georgia, and South Carolina. South Carolina, in particular, was willing to secede but demanded for the secession of the other states as well (Coppieters & Sakwa 2003). Governor Whitemarsh Seabrook had been given advise that other states harbor low judgments of the emotional security and intentions of South Carolina policymakers that if the state decided to act prematurely, other states would refuse to follow (Wakelyn 1996). George W. Towns, the governor of Georgia, requested to the state legislature in September 1850 the permission for a special election to commission representatives to a state conference to give opinion on the Compromise procedures (Huston 2000). John A. Quitman, the expansionist

Nutrition for Health and Social Care (DISCUSSION) Assignment

Nutrition for Health and Social Care (DISCUSSION) - Assignment Example One protein is differentiated from another by the sequence of amino acids, and this is responsible for the tertiary structure that defines the function of the protein. The digestion of proteins takes place in the stomach and the small intestines. In the stomach, pepsinogen is secreted from gastric glands and activated by hydrogen ions to pepsin. Pepsin works on long amino acid chains to produce fragments of various sizes referred to as peptides (Protein Digestion & Absorption , 2005). Protein digestion continues in the small intestines where hydrolysis is accomplished by the action of three proteases including procarboxypeptidase, chymotrypsinogen, and trpsinogen (Murray, et al., 2006). Digestion in the small intestines breaks peptides into smaller chains finally resulting into dipeptides and tripeptides (Protein Digestion & Absorption 2005). Individual amino acids that are yielded at the end of the digestion are absorbed through the cell lining the small intestines into the blood stream. After digestion, proteins are used in the body for various functions. About 20 amino acids are yielded after digestions are used to construct proteins for different functions in the body. Proteins are basically used to produce antibodies, for body tissues (production and repair), production of enzymes and storage of products including amino acids. Most of the fats consumed in diet are in the form of triglycerides (Murray, Harper, Granner, Mayes, & Rodwell 2006). Triglycerides are identified by the presence of a backbone, to which fatty acids are attached. Triglycerides are determined by the type of fatty acids attached, and this varies to a large extend (Murray, et al., 2006). There are three types of fatty acids that are classified depending on the number of double bonds in the molecule. The three are identified as Saturates, Monounsaturates, and polyunsaturates (Rose 2013). Polyunsaturates can

Specific Humoral Immunity B Cells Biology Essay

Specific Humoral Immunity B Cells Biology Essay The immune system is also known as the human defence system; it is made up different cells, tissues, proteins and organs which come together to play different roles in protecting the body from pathogens which are brought about by microorganisms such as: bacteria, parasites and viruses. The main cells which support the immune system include: phagocytes (white blood cells) and lymphocytes. In this section of the assignment, I will highlight the main functions of the immune system; looking specifically at how the cells of the immune system deal with infections after injuries and how this immunity is maintained in the bodys system. How the immune system responds to an infection after a cut in the finger: The human immune system responds to an infection after a cut by the process of inflammation. Inflammation is a non-specific defence response where blood and white blood cells called phagocytes are delivered to the hurt area in order to take immediate action against all kinds of pathogens which have invaded the body. After microbes and other external substances have entered the open cut, a blood clot will be produced to seal the wound in order to prevent other microbes from entering. After this barrier is placed forward, the process of inflammation can then take place effectively: Infected cells such as: mast cells and basophils start to produce chemical mediators such as: histamine. When the histamine is released, it helps increase the blood flow by widening the capillaries and arterioles which in turn increase the amount of oxygen and nutrients needed for inflammation to take place effectively. Increased blood flow also means that there will be more tissue fluid due to the pressure; this formation will not only carry the dead tissue and cells, but will allow them to drain away into the lymphatic vessels. Likewise, the increased permeability of the capillary walls allows the antibodies, white blood cells and plasma fluid to break through the walls and into the swelling tissues (tissue oedema). To finalise the healing process, the histamine attracts the white blood cells (phagocytes) sending them to the injured area where they engulf the microbes; some phagocytes, such as the neutrophils will consume them before dying to form a liquid like substance called: pus. In order to clear the area for new growth, the macrophages will also consume and absorb the microbes. How this immunity is maintained: Immunity is maintained by the adaptive response system (specific), where specialised white blood cells (lymphocytes) work with the phagocytes in order to identify specific antigens on the surface of microbes before they have a chance of invading the body. The two types of lymphocytes that play a part in maintaining immunity are: B-cells and T-cells. Just like B-cells, T-cells are generated in the bone marrow, but the only difference is that they develop in the thymus. Being cell-mediated, these cells will detect antigens both outside the blood and inside the cells before eliminating them. Whether on the outside or inside the cell, the macrophage will present the antigen directly to the T-cells as its surface receptor for stimulation. Following this stimulation, the T-cell will differentiate into four specialised cells which all work differently to maintain immunity: Memory T-cells= these act in the same manner as the memory B-cells to ensure that when the same antigen comes around it is dealt with quickly. Helper T-cells= these work with B-cells to make antibodies and produce a chemical called: cytokines which enables killer T-cells and macrophages to do their job properly. Killer T-cells= these attach to the antigen and demolish it. Suppressor T-cells= these turn off the whole process to prevent damaging effects of the immune system. Likewise, the B-cells are made and grown in the bone marrow and being antibody-mediated (humoral), they will secrete antibodies as surface receptors to help detect antigens in the blood and outside cells. When the antigens have been detected, the T-helper cells will work with the B-cells to expand into other functional cells known as: plasma cells and memory B-cells. The plasma cells will secrete antibodies which will in turn attach to the antigens making them targets for the macrophages as antigen presenters to take to the T- killer cells in order to be demolished. For memory and recognition, the B memory cells will ensure that when the same antigen pops up it is dealt with quickly. For example, once someone has recovered from chicken pox, next time this antigen wants to attack the memory B-cells will recognise the antigen and will instruct the bodys defence mechanisms to attack the antigen with the required amounts of T-killer cells; therefore the body would have a fast and effective way of dealing with the chicken pox to maintain immunity. Task 3 (D2) In order to protect the body against pathogens, the immune system responds in two different ways: non-specific (innate) and specific (adaptive). This section examines and contrasts the dexterity and adeptness of the role of each defence mechanism. The innate (normal) defences are known as immediate because they act quickly to help prevent any type of microbe from invading the body. Whereas adaptive (adjusted) defences only target specific pathogens and due to their delayed response they have to first examine the pathogens before taking action. Non-specific defences: Firstly, the non-specific defence mechanism fall into two categories the first and second line of defence. The first line of defence is made up of physical and chemical barriers; the second line comes under cellular defences such as: inflammation and phagocytosis. The first line of defence also known as external, can be split up into: skin, mucous membranes, secretions and natural substances such as: lysozymes and saliva. The skin and mucous membranes have different characteristics which allow them to keep the microbes away from the surfaces of the body. The skin consists of a strong outer layer which is made of different cells in particular cells covered in a protein substance called: keratin and tissues such as: connective and epithelial tissues which all come together to prevent any microbe from breaking into the skin. This process is aided by the secreted antibacterial sweat and sebum on the surface of the skin. In the same way, mucous membranes which contain ciliated tissues secrete a thick substance called: mucus. The mucus found in areas such as: the nose and throat (respiratory system) helps manoeuvre the microbes and other un-wanted substances away from external and internal areas of the body. Also, the natural chemical barriers such as: tears and saliva consist of an antibacterial enzyme called: lysozome which chemically destroys the bacteria. If this first line of defence fails to work, the now internal second line of defence will act immediately to prevent further invasion. The process which responds to tissue damage (inflammation) will release chemicals such as: histamine, which is designed to promote (phagocytosis) by attracting macrophages and neutrophils to the surface of inflammation in order to enhance healing by engulfing the microbes. Although, these lines of defence are ideal for the body, the pain, swelling and heat brought about each time can cause discomfort after the microbes have entered the body. Specific defences: In contrast to this, adaptive defences hold the third line of defence to help maintain immunity. These are categorised as specific: cell-mediated and humoral (antibody-mediated) defences. After the non-specific defence has completed its job, the specific immune system takes on the role of finishing it off; the two types of lymphocytes involved in the neutralising and then killing of the invading microbes are: B-cells and T-cells. Both cells mature in the bone marrow, but T-cells normally activate in the thymus gland. With the help of T-cells (T-helper cells), B-cells will automatically identify the invaders and respond by producing two functioning cells: plasma cells and memory B-cells. The plasma cells will make the antibodies which attach to the antigen, encouraging the T-killer cells to come along and cause destruction. These cells secrete a chemical called: cytotoxic which immediately kills the antigen. As a result, the T-suppressor cells which have differentiated from the T-cells will turn off the whole immune response, clearing away the mess to get ready for the next attack. After this, due to their ability to remember the B-memory and T-memory cells will be able to prepare for the next antigen that comes to attack. Despite all the advantages of this defence system, the time it takes to react against the invaders is longer than that of the non-specific defence system which enhances the chances of infection in the body for example: if the body cant fight that specific virus quick enough it might lead to certain symptoms such as: flu. Also the fact that the pathogens are specific gives a delayed reaction against other pathogens. Conclusion: In conclusion, each defence system works in its own unique way. However, in my opinion the effectiveness of non-specific defence mechanisms over weighs that of specific defences. Although the processes involved in non-specific defences cause discomfort to the body, the immediate reaction against invaders is easily stimulated to protect the body against further infection. The fact that this defence system is constantly fighting external attacks from different pathogens shows how strong and effective it is. Whereas specific defences take longer to act and can only react to specific invaders which might lead to a weakened immunity system due to multiple infections in the body.

The Legalization of Assisted Suicide :: essays research papers fc

The Legalization of Assisted Suicide   Ã‚  Ã‚  Ã‚  Ã‚  Oregon, the Netherlands, and Belgium are the only three jurisdictions in the world that permit assisted suicide and/or euthanasia. Oregon became the leader of the United States in assisted suicide, when the Oregon legislation passed the Death with Dignity Act in 1994, permitting â€Å"physicians to write prescriptions for a lethal dosage of medication to people with a terminal illness† (Department of Human Services). Oregon’s act specifies who is permitted to assist a terminally ill patient in their time of choosing between life and death. But in the event that the United States as a country legalized assisted suicide, who would determine which patients qualified as terminally ill, and who would be permitted to â€Å"assist† these â€Å"terminally ill† patients? With questions still arising as to how and who on a topic such as assisted suicide, one can only prohibit the action until all aspects have been considered, eliminating confusio n.   Ã‚  Ã‚  Ã‚  Ã‚  Assisted suicide is considered as someone providing another person with information, guidance, and/or means to take his/her own life. It is only considered to be physician assisted suicide (PAS) when a doctor is the provider. In many cases it is the physician who assists a current patient with their final wish of ending his/her life, but what about in other cases? In â€Å"Last Right,† by Carrie Carmichael, Carmichael is asked by her best friend if she (Carmichael’s friend) can jump out of Carmichael’s window. While planning out the action, Carmichael began second-guessing, asking, â€Å"Could I sleep in my room after my friend plunged to her death from my window† (Carmichael, 98)? Not only was Carmichael considering her own emotions, and her own life, but she also considered how the action would affect others: â€Å"Nothing to break her fall. But nothing to protect pedestrians either† (Carmichael, 98). When a person who wishes t o commit suicide pursues assisted suicide, not only is that person affecting themselves, but also those people around them. Carrie Carmichael’s friend had been diagnosed with esophageal cancer, prohibiting her from committing suicide via an over dosage of pills. Carmichael’s friend wanted to commit the suicide before she had became too weak to perform the suicide on her own. In Carrie Carmichael’s case, the â€Å"assistance† provided to her friend was limited because Carmichael drove her friend to the hotel where she would leap from the building, in opposition to those people who injected loved ones with medications or provided the medications for over dosage, only to be provoked to suffocate the family member in time of mishap.

Causes and Effects of the War of 1812

Causes and Effects of The War of 1812 The nineteenth century brought major change to The United States turning it from a developing country into a world power. The addition of Alaska, Oregon, Texas, and Florida, the Mexican Cession and The Louisiana Purchase made The United States a world power. The War of 1812 catalyzed this great expansion. There were four main concerns that led to The War of 1812. Maritime and trade issues, the Embargo Act, territorial expansion, and War Hawks. Although they were major concerns, one alone did not start up the war. â€Å"On June 18, 1812, the United States declared war against Great Britain.In what is often called America's second revolution, the countries were locked in a series of battles for more than two years, which led to few gains on either side. It was one of the most unpopular wars in American history; when its treaty was signed on December 24, 1814, diplomats agreed that the countries should return to the situations they were in before t he start of hostilities. † The troubles with maritime and trade issues on the high seas could have been the biggest concern. As America increased in it’s foreign affairs it began to effect Great Britain and France and their on going quarrel.So President Jefferson declared The United States a neutral power. However this tactic did not work because Britain felt anyone trading with France was an enemy. So from 1803 until 1812 Britain impressed approximately 10,000 Americans, forcing them to work on British ships. And in 1805 Britain decided in The Essex Case that any American commercial ship traveling between enemy or neutral ports will be seized. When word of this British interference and impressments of sailors came back to America citizens were outraged and anti-British feelings began to rise.The Embargo Act was signed on December 22,1807 by Congress under President Jefferson. As a result of tension between Great Britain and France and the risk of losing American ships to either side this act was passed to ban all foreign trade. There was talk of amending the Non-Importation Act and The Secretary of the Treasury Albert Gallatin even suggested going into a full out war, but Jefferson failed to see the benefit of a restrictive economic policy like the Non-Importation Act and preferred a peaceful end.Although it was a noble idea to end the tension with a peaceful means, the act failed to make Great Britain and France respect American rights. The Embargo Act ended up affecting everyone at home more than it did Great Britain or France. The economy of The United States started spiraling downward since the act passed, and the smuggling trade began to increase. â€Å"Although it was successful in averting war, news of evasions and other such negative consequences of the Embargo forced Thomas Jefferson and Congress to consider repealing the measure.The American economy was suffering and the American public opinion was not in support of its continuation. U ltimately, the embargo failed to have a significant effect on the British. Goods still reached Great Britain through illegal shipments; British trade was not suffering as much as the framers of the embargo had intended†. The act only had a major effect at home; making Americans furious Britain would not open up free trade. Britain began to see the increasing tension between themselves and the United States, so British officers in Canada began making friends with Indians residing in the Northwest region of The United States.It was easy for Britain to befriend the Native Americans because they felt threatened by Americans and their desire to push westward, and take their land. One of the greatest Indian chiefs in North American history, a Shawnee chief, Tecumseh, prepared to protect their land. He began by traveling the Mississippi valley as far south as Tennessee looking for assistance to create an Indian confederacy strong enough to fight the Americans. He enlisted his brother , Prophet, to begin to unite the tribes of the west to fight against Americans.A disagreement broke out over an American purchase of three million acres of land in Indian Territory. In a battle outside of Prophet’s town of Tippecanoe River, Prophet foolishly decided to attack American militiamen while they were sleeping. The town was torched in the battle that followed, and years of planning and organization was wasted. After this incident in June 1812, Tecumseh and a small company of Native Americans joined the British at Amherstburg. During the war, American’s called for an invasion of Canada mainly because the support the British gave to American Indians.In the Battle of Thames, Tecumseh died and an American victory is gained. The War Hawks were a number of young representatives voted into the twelfth congress. They were typically people from southern and western states like Henry Clay, Speaker of the House at the time, John Calhoun of Kentucky and Langdon Cheves of South Carolina who spoke in Congress advocating going to war with Great Britain. They believed it was our right to expansion, and declared that a thousand Kentucky riflemen could take on Canada alone. They expected the war to be short, considering the British were in Europe fighting Napoleon.Although opposed by the Federalist of New York, New Jersey, and most of New England, on June 18, 1812 James Madison declared war on Great Britain. â€Å"However the War Hawks had displayed much more energy in talking about war than in planning and preparing for war. At the beginning of hostilities there were about 7,000 men in the regular forces and these were commanded by senior officers who were old, incompetent or lacking in experience. Congress had voted for war, but seemed reluctant to spend the necessary funds upon equipment and supplies.A bill introduced into Congress with the purpose of increasing the size of the American Navy was turned down by the members. Volunteer soldiers were bad ly fed and disgracefully clothed. In winter, the unfortunate sentries who patrolled the Canadian-American border shivered and shook on duty because they lacked overcoats. † Some historians say the war hawks are the ones to blame for the war, because they wanted to wage a war knowing the United States military was inadequate at the time. The war ended December 24,1814 with The Treaty of Ghent. Not a single senator voted against peace.Although the war did not have much effect at the time, besides gaining land conquered during battle, the effect of the War of 1812 would become grate. After the war, America gained international respect for resisting Great Britain’s control for the second time in less than forty years. Also, marking the last armed conflict between the two countries. Not only did the war prove the United States military, but also it’s army. It gave The United States battle tested leaders, and the opportunity to train servicemen; which proves to be need ed to expand by land acquisitions from the Spanish-American and Mexican-American Wars.The British blockade leading up to the War of 1812 strengthened the United States economy by requiring workers to manufacture most goods normally imported, diminishing foreign dependence. After the federalist did not support the war and were considered traitors for attempting to secede at the Hartford Convention, the party was destroyed. The end to this party marked an era of Good Feeling for the United States, since they did not have to deal with inter-party disputes. â€Å"Manifest Destiny†, America’s destiny to span from the Atlantic to the Pacific, would not be possible without the courage and wisdom The War of 1812 gave America.The military would not have be what it is today without taking off the way it did after the war, or the nationalism Americans felt and have been able to span the difference between the oceans. Many nations saw how The United States struggled but kept holdi ng on throughout the war to come to a peaceful agreement. By showing this, America became a force to be reckoned with and would prove to be a world power.

History of organic chemistry Essay

Chemistry has been called the science of what things are. Its intent is the exploration of the nature of the materials that fabricate our physical environment, why they hold the different properties that depict them, how their atomic structure may be fathomed, and how they may be manipulated and changed. Although organic reactions have been conducted by man since the discovery of fire, the science of Organic chemistry did not develop until the turn of the eighteenth century, mainly in France at first, then in Germany, later on in England. By far the largest variety of materials that bombard us are made up of organic elements. The beginning of the Ninetieth century was also the dawn of chemistry, all organic substances were understood as all being materials produced by living organisms: wood, bone, cloth, food, medicines, and the complex substances that configure the human body. Inorganic material was believed to come from the Earth: salt, metals, and rock, just to name a few. Because of the human’s wonder of natural life, organic materials were believed to possess an enigmatic â€Å"Vital Force.† Thus organic chemistry was separated from inorganic chemistry, and it became it’s own field of science. By the turn of the Nineteenth the â€Å"Vital Force† theory was immensely discredited, but this branch of science still stayed separated from inorganic chemistry. Back when Organic chemistry was the chemistry of living matter, Professor Wohler succeeded in synthesizing in the labo†¦ The name organic chemistry came from the word organism. Prior to 1828, all organic compounds had been obtained from organisms or their remains. The scientific philosophy back then was that the synthesis of organic compounds could only be produced within living matter while inorganic compounds were synthesized from non-living matter. A theory known as â€Å"Vitalism† stated that a â€Å"vital force† from living organisms was necessary to make an organic compound. 1828, a German chemist Friedrich Wà ¶hler (1800-1882) amazed the science community by using the inorganic compound ammonium cyanate, NH4OCN to synthesize urea, H2NCONH2, an organic substance found in the urine of many animals. This led to the disappearance of the â€Å"Vitalism† theory. Today, chemists consider organic compounds to be those containing carbon and  one or more other elements, most often hydrogen, oxygen, nitrogen, sulfur, or the halogens, but sometimes others as well. Organic chemistry is defined as the chemistry of carbon and its compounds. Organic chemistry is also known under the short-term organic. The organic chemistry as a branch of chemistry can be viewed and engaged in the carbon content. Particularly the structure, composition and the chemical reactions of carbon will be investigated. To the organic chemistry include the elements that go with the carbon compounds. Therefore we understand today as the organic chemistry, the chemistry of carbon compounds, and not focusing only on the compounds from nature. The organic chemistry is, however, also limits for inorganic chemistry. This limit is usually denied to the concept of hydrocyanic acid. The division of natural science in organic chemistry and inorganic chemistry is historical. The term â€Å"organic† was first used by Berzilius about 1810 because by then all investigated compounds derived from living organisms and in the laboratory could not be synthesized. Berzilius found it impossible to produce organic compounds from nature artificial. This theory was refuted, however, then in 1828 by the chemist Friedrich Wohler. In later times it was always more to produce organic substances synthetically, which contained all the carbon. The simplest organic compounds consist only of the elements of water and carbon. Only compounds such as carbon oxides, carbonates, carbides and cyanides are expected to inorganic compounds. Before the nineteenth century, chemists generally believed that compounds obtained from living organisms were endowed with a vital force that distinguished them from inorganic compounds. According to the concept of vitalism (vital force theory), organic matter was endowed with a â€Å"vital force†.[8] During the first half of the nineteenth century, some of the first systematic studies of organic compounds were reported. Around 1816 Michel Chevreul started a study of soaps made from various fats and alkalis. He separated the different acids that, in combination with the alkali, produced the soap. Since these were all individual compounds, he demonstrated that it was possible to make a chemical change in various fats  (which traditionally come from organic sources), producing new compounds, without â€Å"vital force†. In 1828 Friedrich Wà ¶hler produced the organic chemical urea (carbamide), a constituent of urine, from the inorganic ammonium cyanate NH4CNO, in what i s now called the Wà ¶hler synthesis. Although Wà ¶hler was always cautious about claiming that he had disproved the theory of vital force, this event has often been thought of as a turning point.[8] In 1856 William Henry Perkin, while trying to manufacture quinine, accidentally manufactured the organic dye now known as Perkin’s mauve. Through its great financial success, this discovery greatly increased interest in organic chemistry.[9] The crucial breakthrough for organic chemistry was the concept of chemical structure, developed independently and simultaneously by Friedrich August Kekulà © and Archibald Scott Couper in 1858.[10] Both men suggested that tetravalent carbon atoms could link to each other to form a carbon lattice, and that the detailed patterns of atomic bonding could be discerned by skillful interpretations of appropriate chemical reactions. The pharmaceutical industry began in the last decade of the 19th century when the manufacturing of acetylsalicylic acid (more commonly referred to as aspirin) in Germany was started by Bayer.[11] The first time a drug was systematically improved was with arsphenamine (Salvarsan). Though numerous derivatives of the dangerous toxic atoxyl were examined by Paul Ehrlich and his group, the compound with best effectiveness and toxicity characteristics was selected for production.[citation needed] Early examples of organic reactions and applications were often serendipitous. The latter half of the 19th century however witnessed systematic studies of organic compounds, Illustrative is the development of synthetic indigo. The production of indigo from plant sources dropped from 19,000 tons in 1897 to 1,000 tons by 1914 thanks to the synthetic methods developed by Adolf von Baeyer. In 2002, 17,000 tons of synthetic indigo were produced from petrochemicals.[12] In the early part of the 20th Century, polymers and enzymes were shown to be large organic molecules, and petroleum was shown to be of biological origin. The multistep synthesis of complex organic compounds is called total synthesis. Total synthesis of complex natural compounds increased in complexity to glucose and terpineol. For example, cholesterol-related compounds have opened ways to synthesize complex human hormones and their modified derivatives. Since the start of the 20th century, complexity of total syntheses has been increased to include molecules of high complexity such as lysergic acid and vitamin B12.[13] The total synthesis of vitamin B12 marked a major achievement in organic chemistry. The development of organic chemistry benefited from the discovery of petroleum and the development of the petrochemical industry. The conversion of individual compounds obtained from petroleum into different compound types by various chemical processes led to the birth of the petrochemical industry, which successfully manufactured artificial rubbers, various organic adhesives, property-modifying petroleum additives, and plastics. The majority of chemical compounds occurring in biological organisms are in fact carbon compounds, so the association between organic chemistry and biochemistry is so close that biochemistry might be regarded as in essence a branch of organic chemistry. Although the history of biochemistry might be taken to span some four centuries, fundamental understanding of the field only began to develop in the late 19th century and the actual term biochemistry was coined around the start of 20th century. Research in the field increased throughout the twentieth century, without any indication of slackening in the rate of increase, as may be verified by inspection of abstraction and indexing services such as BIOSIS Previews and Biological Abstracts, which began in the 1920s as a single annual volume, but has grown so drastically that by the end of the 20th century it was only available to the everyday user as an online electronic database.[14] The Importance of Chemistry in Everyday Life During laboratory technique 1 we learned how to separate insoluble liquids from solids by means of filtration, and how to separate a dissolved solid from a liquid by means of evaporation. I have often asked myself the importance of some of the required classes in my schedule and how they can relate to everyday life. I believe in the saying that if you don’t use it you will lose it, meaning that if the concepts I learn cannot be applied to something that I will remember on a daily basis then the possibilities of me not remembering them at all are greater. This is especially true if you’re not a science or medical major as I am not. However in this class I am discovering that things we are learning can definitely be applied to processes that my mind uses daily and procedures that are performed daily and are as close to me as my own kitchen. In pondering the idea of filtration and evaporation I begin to think of the water that I drink on a daily basis. Without even being aware of the process I have been using filtration on a daily basis. I purchased a filter for my sink a number of years ago to improve the taste of my water and get rid of what I called the (bad things) that my body didn’t need. At the time I had no idea I was making a scientific decision and using a scientific method. I had determined that the water in my house did not taste well and that the taste could be improved. Listening to others who had boasted about the success of filtered water I decided to test their hypothesis out for myself. I bought from the local hardware store a basic water filter system that could be attached to the faucet of your sink. Supposedly this water filter would remove the harmful substances from my water and improve the taste. I tested the hypothesis by first pouring myself a glass of unfiltered water and sitting it aside. I then attached my filter system and poured myself a glass of filtered water. I tasted both and observed the differences in each taste. The hypothesis was now justified in my eyes, the filtered water tasted better. I offered my hypothesis to my husband and children and allowed them to make their own observations. We all agreed that the filtered water tested better. The hypothesis had now become theory in my household. Now since this class I’ve been observing just how this filter system works. I have discovered that the residue that remains after filtering in some way affected the taste of my regular tap water. I have since learned that this residue consists of salt and other stuff that could definitely dramatically affect the test. Interestingly enough though, this filtration process didn’t start with me. Scientist years ago began to filter water for health reasons. Elements that are deadly to our human bodies (such as chloride) are filtered out daily through our elaborate water system to ensure that our water is healthy to drink. Without this process we would have entire cities dying just like the colony of Jamestown centuries ago! Wow I guess science is a necessary in my daily life, I just never knew that’s what it was called.
