Carbon Fiber report Table of Contents Introduction 3 Historical events of Carbon fiber 3 Properties 4 Applications 4 Conclusion 5 Bibliography 6 Introduction There are a lot of new materials that has emerged and been used by engineers and scientists such as Aerogel, Metal foam, Bioplastic, Carbon fiber, Graphene and others. This is helping engineers build all new types of machines and instruments such as touch screen mobiles, automobile sensors, computers, planes and a lot more.This report will focus on a certain material called Carbon fiber. This material is being used lot due to It Is properties, for example Carbon fiber is five times stronger than steel and weighs three times less. Most cars use steel for body parts but imagine replacing steel with carbon fiber that would open a whole new road for car industries. The report will discuss some historical events and background information about carbon fiber. Also, it will focus on carbon fiber properties and two applications for It.H istorical events of Carbon fiber In the late 1800s Thomas Edison carbonized bamboo and cotton to produce filaments for his light bulbs Oohnson. n. d. ). In 1958 Roger Bacon created high performance carbon fibers at the Union Carbide. His method was to heat strands of a material called rayon (artificial silk) until they are carbonized, but this method proved to be inadequate because the resulting fibers had only carried 20% of carbon and the properties of it were Inefficient, such as low strength and stiffness (â€Å"Carbon (fiber) ,n. d. † ).In the early 1960s the process of Carbon fber was developed by Dr. Akio Shindo at Agency Of Industrial Science and Technology of Japan, which improved carbon fiber and contained 50% of carbon (â€Å"Carbon (fiber), n. d. In 1963, the properties of carbon fiber were acknowledged, such as high strength, by W. Watt, L. N. Philips and W. Johnson at the Royal Aircraft Establishment at Farnborough, Hampshire (â€Å"Carbon (fiber), n. d. † ). In the early 1960s, engineers began applying carbon fiber to aircraft because of it Is properties like high strength and light weight.The results of using carbon fiber In this area made aircraft much lighter, faster and also heat resistant due to the aircraft Itself and atmospherically (Johnson, n. d. ). 1 OF3 Between tne years a IYBU, Caroon TIDer was manuTacturea to De given to tne ilitary and also was produced to be used in sports such as NASCAR and Formula 1 to make the vehicles lighter and faster Oohnson, n. d. ). In the early 21st century, the manufacturing of Carbon fiber had expanded greatly through Asia, Europe and the United states, because the industries had been requesting Carbon fiber, industries such as sports and aerospace Oohnson, n. . ). Properties Carbon fiber is a material that belongs to the family of polymers. It is made with an extremely thin strings of carbon (like hair) that are twisted, then the strings are oven together to make it look like a piece of fabric. To make the shape of the fabric- carbon permanent is to place it over a selected mold or any shape that is desired and then it is covered with a stiff liquid resin or liquid plastic. Finally, it dries up to maintain the selected shape (Deaton, n. d. . Carbon fiber has a lot of amazing properties and characteristics, such as high strength and high rigidity, even though it is relatively light; it is like the property of steel's strength and the lightness of plastic combined in one material. Also, Carbon fiber resists fire and heat because the aterial itself reflects heat competently if it is in a condition of a dense layer, which leads us to the matter of expansion due to heat; this material has a low expansion to heat unlike steel.Comparing steel to Carbon fiber, steel has a low corrosion resistivity which means it is more susceptible to rust unlike carbon fiber that has a high corrosion resistivity (â€Å"Carbon fiber characteristics, n. d. † ). Carbon fiber can abso rb vibration, in other words a good vibration damping (Kiron, n. d. ). which opens a door to set or attach carbon fiber to moving machines or automobiles. Moreover, Carbon fiber appears in x-ray vision thus it cannot be stolen or for any illegal activity. Also, in a medical view, Carbon fiber is being used to support limbs or injured knees but this study is still to be researched Oohnson, n. . ). Applications Carbon fiber can be used in so many ways; it can be customized for customer's desire. In this section two applications will be discussed which are automotive and military. Carbon fiber is used for automobile racing and styling, for example car parts such as the hood (bonnet) for it is heat resistivity, trunk, lip, fender, car rims (wheels) nd much more to make the car lighter, faster, able to absorb vibration and more attractive. In addition, if the car is lighter it means that less fuel will be used.Also, the bodies of motorcycle racing which are called fairings are made out o f Carbon fiber; these fairings are especially designed for racing. Exhausts (mufflers) are also made out of carbon fiber for both cars and motorcycles for carbon's fiber heat resistivity and sound. Carbon fiber not only plays an important role in the racing world but also will play in the normal daily world in cars (â€Å"Carbon (fiber),n. d. † ). Carbon fiber is used in the military; it is used in planes, tanks, military cars, missiles even soldier's personal gear such as a helmet, boots, rifles, armor other equipment.Less weight means less energy and faster movement whether if it is a vehicle or a human. Of course there is a lot of information for using Carbon fiber for military reasons, but it is classified, only shallow information is given to civilians Oohnson, n. d. ). Conclusion 10 sum up, tne nlstory 0T Caroon TIDer was 01scussea ana looked Into tnrougnout tne years of development and the people who played an important role in the history of his material were introduc ed. Also, the family of the material was identified and the making of Carbon fiber was explained thoroughly.Carbon fiber has outstanding properties such as high rigidity, strength and low weight. To add, Carbon fiber has been widely used in applications such as automobiles and military. These two examples are two of many applications that are being used for carbon fiber in everyday life. Although carbon fiber can be very expensive, it is still used in many industries. Engineers can use Carbon fiber in many designs in various applications hat can be used for people such as modern bicycles, cars, baseball bats, fishing rods and much more.https://en.wikipedia.org/wiki/Carbon-based_lifehttp://auto.howstuffworks.com/fuel-efficiency/fuel-economy/carbon-fiber-oil-crisis.htmhttps://www.thoughtco.com/uses-of-carbon-fiber-820394https://www.thoughtco.com/applications-of-carbon-fiber-820384http://textilelearner.blogspot.com/http://www.christinedemerchant.com/carboncharacteristics.htmlhttps://ai tracing.com/

Alcohol Vignette

Tom has been arrested twice for Driving Under the Influence or DUI of alcohol, and in his most recent arrest, he has also been charged with assault of a law enforcement officer which is specifically a display of seemingly violent behavior since assault involves physical attack or onslaught.Tom’s blood alcohol level or BAL taken when he was arrested was 0.18 which was identified as the blood level for illegal intoxication (Hamilton, 2007). Aside from Tom’s BAL as indicator of his intoxication, he also admitted to forgetting what had transpired, his pupils were dilated, his speech was mildly impaired, and he displayed lethargic behavior. Assessing Tom’s situation was taken under the context of his claim that the case only happens during social gatherings with family and friends, not motivated by problems and such.Considering the circumstances presented, I would have to say that Tom is an alcohol abuser based on the guidelines set by The Diagnostic and Statistical M anual of Mental Disorders IV. An alcohol abuser is described as an individual who drinks alcohol in a manner that is harmful or hazardous to one’s health. (Buddy, 2008)Since Tom’s memory, speech, and physical functioning was affected by his high levels of alcohol intake, he fits into the category of an alcohol abuser. Another characteristic established and attributed to alcohol abusers include the non-dependence on alcohol.Alcohol abusers do not show strong cravings or dependence toward drinking. (â€Å"What is Alcohol Abuse?,† 2003) Basing it on Tom’s claim of having been drinking only after the holidays and during social gatherings, it clearly reveals that he does not exhibit strong cravings and dependence toward alcohol intoxication.Other characteristics of alcohol abusers that might be exhibited during a year-round observation includes recurrent apprehension for being caught due to reasons pertaining to alcohol, and other offenses that are fueled by a lcohol intoxication (ex. assault, etc.), and drinking without control or setting limitations despite having legal problems (ex. DUI arrests, etc.) in the past that were related to alcohol intoxication. (â€Å"What is Alcohol Abuse?,† 2003)Aside from the standards or guidelines that determines between alcohol abuse and alcohol dependence, there are other standards established over the years that are used to categorize drinking patterns or problems – specifically, Type I and Type II alcoholism, and Type A and B alcoholism.Type I alcoholism is attributed to alcoholism for both the male and female populations that occurs in the latter ages of life with noticeably less serious effects or implications, specifically with actions or behaviors that are related to anti-social behavior or misdemeanor. Type II alcoholism on the other hand, is isolated to the male population that starts at an early age with serious effects and implications, particularly when it comes to the display of anti-social behavior or misdemeanor. (Johnson, 1996)Type A and Type B alcoholism are based on standards or guidelines that relate the magnitude or gravity of alcoholism to an individuals childhood background, time of use, dependence on alcohol, use of illegal drugs, and the efficiency of treatment.Alcoholics under Type A are those who started drinking in the latter part of their lives, with no known or minor emotional or psychological problems in their childhood, lesser dependence on alcohol and problems or issues that are related to intoxication. On the other hand, alcoholics under Type B are those who have experienced emotional or psychological problems in their younger years, have family members who are also alcoholic, greatly dependent on alcohol, and more alcohol-related problems. (Babor, et. al., 1992)Based on the above descriptions of Type I and Type II, and Type A and Type B alcoholism, Tom is more likely to be categorized as an alcohol abuser under Type II and Type B in progress.This is supported by the fact that Tom is starting to follow a pattern of alcoholism that leads him to become publicly arrested for being illegally intoxicated. Moreover, Tom has already displayed violent behavior towards a law enforcement officer, which he claims he does not recall. Since he was already arrested in the past for a DUI, and he was arrested again for the same offense, he refuses to acknowledge his drinking problem and the harmful effects that it poses to his health and safety as well as the safety of other people.2. Tom mentioned that he does not remember anything that happened while he was intoxicated, which obviously means that his being drunk is affecting his memory. Moreover, he displays mild speech impairment as well as lethargic behavior or demeanor.The implications of such admissions and overt behavior lead to the conjecture that there is something wrong with Tom, particularly the functioning of his Central Nervous System or CNS. The CNS is composed o f an individual’s brain, spinal column, and nerves or neurons. In general, drinking alcohol of any amount affects the CNS. However, it is the amount of alcohol which determines how strong or overpowering its effect would be to the physical and cognitive functioning of a human being.   (Dunlap, N.D.)Naturally, when an individual drinks too much alcohol, its effects would also be greater on the functioning of his CNS. Since the CNS is capable of handling the senses and the impulses which governs an individual’s thoughts and actions. As an individual continues to drink alcohol, the CNS also continues to depreciate causing irreversible or irreparable damage to an individual’s CNS functioning.Apparently, the content of alcohol which goes directly to an individual’s CNS, blocks out the circulation of oxygen to and from the brain which causes a temporary blackout blurring or blocking one’s memory. Once the alcohol dissipates from the body, the circulati on of oxygen in the brain normalizes, as well as an individual’s memory. This means that once an individual becomes a habitual drinker, his memory as governed by the functioning of his brain, and his impulses or senses as managed by his nerves and neurons, become permanently damaged by alcohol. (Dunlap, N.D.)The kind of behavior displayed by Tom is clear signs of CNS impairments or disabilities caused by his intake of alcohol. For instance, Cerebellar Atrophy is a condition associated to a part of the brain called the cerebellum, wherein an individual’s intake of alcohol causes an imbalance or disturbance in one’s muscle coordination. Cerebellar Atrophy will affect an individual’s balance as well as walking movements.This particular CNS condition explains why Tom’s actions or movements are lethargic or sluggish since he had trouble balancing, walking, or moving at a normal pace. Another condition related to alcohol and the CNS is the Korsakoff†™s Amnesic Syndrome. This particular syndrome has something to do with an individual’s memory. If an individual develops high dependency on alcohol and takes in alcohol that is more than the amount of normal intake, contracting Korsakoff’s Amnesic Syndrome will lead to losses in short-term memory. (â€Å"Alcohol Related Brain Impairment,† 2008)One factor which affects the length of time by which alcohol lingers inside the body, therefore, shortening or prolonging the harmful and incapacitating effects of alcohol to an individuals CNS is his metabolism. Metabolism is a process that occurs within the body which converts substances and other chemical compounds that are readily excreted from the human body.The process constitutes the contribution of the liver in the oxidization process which normalizes the amount of oxygen in the blood stream, including the brain. If the oxidization process is normal, then the rate of an individual’s return to consciousness is normal.However, the rate of the oxidization process as well as the metabolizing enzymes found in the liver is greatly affected by alcohol. Large amounts of alcohol intake will lead to the damage of an individual’s liver which will consequently influence metabolism rate, making it difficult for the liver to dissipate alcohol from the human body prolonging the effects of alcohol to an individual’s brain functioning. (â€Å"Alcohol and The Human Body,† N.D.)Since the effect of Tom’s alcohol intake was observable prior to his arrest which motivated a DUI charge until the time that he was apprehended, displaying bouts of memory loss, speech impairment, and lethargy, this means that the rate of his metabolism is not capable of flushing out alcohol from his system and normalizing his bodily functions through immediate oxidization.From this, we learn that Tom is an alcoholic who have been drinking alcohol either for a long time or in large amounts which is en ough to interfere with his metabolism.Tom’s stated case or situation and gathered information pertaining to the simultaneous intake of certain drugs such as Marijuana, Valium and other types of downers, and alcohol will be used to identify whether he used downers along with alcohol or not. Again, observable behaviors that may be utilized to answer such inquiry include his sudden loss of short-term memory, the dilation of his pupils, mild speech impairment, and lethargic behavior or demeanor.First, we need to understand the results or effects of drinking downers along with alcohol, differentiating it from the symptoms of alcoholism alone. Downers or depressants are intended for decreasing brain functioning or activity within the individual’s CNS in order to ease anxieties, worries, tensions, stresses, and such.Downers or depressants are appropriately prescribed for individuals who need to calm down as a means of moderating psychological tension. Since the intake of alco hol seems to display similarities to the effects of downers, the intake of alcohol and downers or depressants at the same time magnifies the effects or results of each when taken separately.

Sustainability and Innovation in Business Essay Example | Topics and Well Written Essays - 500 words

Sustainability and Innovation in Business - Essay Example In order to lead in the competition, the company needs to keep on innovating through sustainability (Nidumolu & Et. Al., â€Å"Why Sustainability Is Now The Key Driver Of Innovation†). Firstly, the company should comply with the specifications of the industry by abiding the governmental rules as well as regulations. The company needs to take heed of the emissions in their manufacturing plants and the usage of water. They should invest in new and advanced technological equipments in order to reduce the effect of their manufacturing activities on the environment. Ford needs to adopt measures to trim down the carbon emissions as well as cut down on the usage of water in order to conserve it with the introduction of advanced technological facilities. The company also needs to take care of its value chains in order to make them sustainable. Abiding by the regulations would assist the company to be environmentally conscious which would therefore make them take a notice on their resource consumption activities. They should take steps in order to trim down wastages and consumptions in their internal operations and in their workplace surroundings. After this a proper look should be provided in their arrangement of supply chain so that efficiency is escalated with the help of every individual association that forms a part of their supply chain. This would help the company to get familiar with advanced and new technologies which would pave the way for further innovation in terms of fresh product designs as well as in their business. This step would surely help them to attain sustainability (Ford, â€Å"Sustainability†; Nidumolu & Et. Al., â€Å"Why Sustainability Is Now The Key Driver Of Innovation†). The amplified emphasis on competence and freshly attained familiarity with technologies and expertise would help them to consider redesigning their offered products and take advantage of the increasing

Economics factors as barriers to effective Health Care Term Paper

Economics factors as barriers to effective Health Care - Term Paper Example According to Patricia & Mary (2007) ensuring a health rich globe, may take a million years if all health hazards remained constant. With this scenario impossible it becomes the duty of nations and health bodies to protect their citizens against health hazards. Making it hard to control global health is the fact that there are emergences of diseases which have no permanent treatment yet. However, other factors play a major role in the hindrance of provision of health care. These factors are influenced mostly by human activity. They mostly include economic and social factors. In many occasions social factors get all the attention disregarding the influence of the economic factors. In an argument by Ralph (2011) economic factors pose many threats than social factors yet they don’t get enough attention as the social factors. Economic factors that hinder effective health care include poverty, job descriptions and illegal trade of counterfeit drugs. The three factors are the leading economic factors that affect the global front in terms of provision of effective health care. This paper will focus on these three economic factors as barriers to proper provision of health care. Additionally, the paper will provide guidelines which may effectively address these issues. Also included will be the probability of the issues to be addressed permanently and effectively. Economic factors Poverty levels In words by Roslyn & Rick (2008) poverty is the largest hindrance to access of quality health care in many nations. The most affected nations are in their third world stage of evolution. Nations in the third world have large numbers of their population living under the poverty level line. This is greatly attributed to the fact that unemployment levels are at high levels. As a general assumption in many third world countries, basic needs are the first priority. Health care does not fall under the brackets of basic needs in these parts of the globe. Due to poverty levels lar ge numbers of populations prefer to use over the counter drugs to treat any form of illness. According to Simon & Heather (2007) this tendency is an evidence of how quality health care is made difficult to obtain. For the past five years thousands of people have succumbed to diseases due to lack of proper health care. Health researchers argue that it is not out of will that individual choose to seek poor health care. If given the chance and ability, every single individual on the face of the earth would opt to seek the best health care services. The living conditions and financial abilities determine the quality of health care one can get. It is for this reason that health bodies advocate for free provision of health care when it comes to very serious diseases. A good example is the treatment of HIV/ Aids. The treatment of HIV/Aids was made voluntary and free since the medication of the ARVs was too expensive. This step made it possible for people with poor living standards t access the medication. the results of this move is very significant as there is evidence of people living with the virus and live up to seven years before succumbing to death (Mwabu & Ishola, 2010). In an argument by Tracy (2009) it is an obvious assumption that a person living below a dollar per day may put proper medication as a last need in their budget. Poverty or low income levels also affect nations. Below the third world nations there are nations with low revenue

Climate change Essay Example | Topics and Well Written Essays - 750 words

Climate change - Essay Example Researchers have the view that the temperature has risen by 0.8 -1o on the Celsius scale globally. The increase in the temperature may look small but it may bring a bigger difference in some of the temperature sensitive environments. The melting of the Atlantic Glaciers and glaciers at some other regions depicts the situation due to the climate change. Ecosystems and Climate Change Ecosystem plays a significant role in shaping the livelihood of the earth. However, the observed effects of the climate change are not such adverse that are estimated, as some of the organisms have the capability to adjust with the climate change. Some of the organisms within the island ecosystem such as coral reefs are much influenced with the little degree rise in the temperature (FAO 3-79). Like the Pacific Island’s mangrove area may decline from 1% to 13% as the temperature increases from 2o to 4o. In the Islands at higher altitudes, the temperature increase is causing the show to melt and thus endangering some species by increasing the amount of invasive species. Moreover, the increase in the level of the sea water might become a reason for the bleaching of the coral reef and effecting the reproduction of the coral reefs and thus lessening the life of the coral reefs. Coral reefs are important in becoming a reason for providing the other species like fish, shelter and food. Biodiversity can be influenced by the events such as the cyclones, where the repetitions of the cyclones are increased. With just an increase of 2% in the temperature, the intensities of the cyclones are increased by 12 or 15% (IFAD, n.pag.). Moreover, the climate change impacted the generation of ice over the... Natural processes have a set impact on the earth’s climate; however, the utilization of the fossil fuel sources to produce energy has produced many problems. The most distinguished problem of the burning of the fossil fuel is the emission of the green house gases. The green house gases are named due to having the ability to trap the solar radiations inside the earth’s atmosphere in the presence of water vapors in the atmosphere. In this way, the solar radiation never go back to the space and constantly warm up the earth’s atmosphere. The green house effect is created artificially in the green houses to develop certain plant species. Human activity is the major cause of the climate change. The utilization of the fossil fuel resources to attain energy is highly impacting the earth’s climate. There is a need reduce the utilization of the fossil fuel resources, as fossil fuels produce green house gas emissions that are capable of trapping the solar radiations. It is recommended to utilize the sustainable and renewable resources to produce energy like solar, wind, geothermal, hydropower, etc. as sustainable and renewable resources produce no or little green house gas emissions. If it is not feasible to utilize the renewable resources, the fossil fuel resources that lave lower percentage of emission must be utilized like natural gas is better than both coal and oil, as it has lower quantity of emissions. There is need to control the climate change for the existence of the human life and for the existence of our planet.

Analysis of Education Reforms Research Paper Example | Topics and Well Written Essays - 1500 words

Analysis of Education Reforms - Research Paper Example The meaning of education has changed severally throughout history. This has been due to debates by scholars over what experiences and content result in an individual or society being educated. Education can be formal and informal. Formal education refers to the organized process of instructing, developing and training individuals within a formally structured, certified and approved program or environment. Formal education follows a pre-described curriculum that is administered by trained and qualified personnel. It is usually supported by governments and it leads to formal certification. Informal education, on the other hand, refers to education that takes place outside a formally structured and organized school environment. It is usually not compulsory and some governments may support it while others may not. Formal certification is not given for informal education (Guthrie 43). Generally, formal education in most jurisdictions begins at pre-school. It then proceeds to primary schoo l, secondary school and finally to higher education. The demand for improved education and the efforts towards high-quality standards have necessitated education reforms in the education sector. Education reform is broadly interpreted to mean the major change in how individuals formally access information and knowledge. Education reforms can be implemented by enforcing broad changes in the curriculum. The reforms can also be implemented by educational stakeholders and individual educators (Blackburn 19). This paper focuses on the stands of ancient scholars concerning education and the opinions of modern reformists on the same. It also highlights my position as the writer and which side I agree with. It describes why I subscribe to the school of thought that I have chosen and why I think the ancient schools of thought were misleading. According to Plato, children can never be forced to learn! They can only learn effectively if they want to. In his book, The Republic, he says that lea rning which is compulsory will never stick in the mind of the learner. However, modern education reforms focus on the spread of compulsory education worldwide. Those who subscribe to this school of thought claim that there were no widespread educational reforms until organized schooling became adequately systematized. Personally, I vehemently disagree with Plato and all those who subscribed to his school of thought. I believe in compulsory education for all. Compulsory education may be described as a period whereby all persons that fall under a prescribed age group, usually 6 to 16 years, attend formal educational facilities. It may also be the compulsory educational attendance of all persons up to a certain grade. In the modern world, democracy, economic growth, and compulsory education have improved the quality, attendance, and value of education. They have created an awareness of the importance of education for all (Swassing 28). I believe that all persons, children or adults, sh ould have continuous access to effective and high-quality education.  Ã‚
