Prolonged Preservation of the Heart Prior to Trans Essays

Prolonged Preservation of the Heart Prior to Trans Essays Prolonged Preservation of the Heart Prior to Transplantation Biochemistry Prolonged Preservation of the Heart Prior to Transplantation Picture this. A man is involved in a severe car crash in Florida which has left him brain-dead with no hope for any kind of recovery. The majority of his vital organs are still functional and the man has designated that his organs be donated to a needy person upon his untimely death. Meanwhile, upon checking with the donor registry board, it is discovered that the best match for receiving the heart of the Florida man is a male in Oregon who is in desperate need of a heart transplant. Without the transplant, the man will most certainly die within 48 hours. The second man's tissues match up perfectly with the brain-dead man's in Florida. This seems like an excellent opportunity for a heart transplant. However, a transplant is currently not a viable option for the Oregon man since he is separated by such a vast geographic distance from the organ. Scientists and doctors are currently only able to keep a donor heart viable for four hours before the tissues become irreversibly damaged. Because of this preservation restriction, the donor heart is ultimately given to someone whose tissues do not match up as well, so there is a greatly increased chance for rejection of the organ by the recipient. As far as the man in Oregon goes, he will probably not receive a donor heart before his own expires. Currently, when a heart is being prepared for transplantation, it is simply submerged in an isotonic saline ice bath in an attempt to stop all metabolic activity of that heart. This cold submersion technique is adequate for only four hours. However, if the heart is perfused with the proper media, it can remain viable for up to 24 hours. The technique of perfusion is based on intrinsically simple principles. What occurs is a physician carefully excises the heart from the donor. He then accurately trims the vessels of the heart so they can be easily attached to the perfusion apparatus. After trimming, a cannula is inserted into the superior vena cava. Through this cannula, the preservation media can be pumped in. What if this scenario were different? What if doctors were able to preserve the donor heart and keep it viable outside the body for up to 24 hours instead of only four hours? If this were possible, the heart in Florida could have been transported across the country to Oregon where the perfect recipient waited. The biochemical composition of the preservation media for hearts during the transplant delay is drastically important for prolonging the viability of the organ. If a media can be developed that could preserve the heart for longer periods of time, many lives could be saved as a result. Another benefit of this increase in time is that it would allow doctors the time to better prepare themselves for the lengthy operation. The accidents that render people brain-dead often occur at night or in the early morning. Presently, as soon as a donor organ becomes available, doctors must immediately go to work at transplanting it. This extremely intricate and intense operation takes a long time to complete. If the transplanting doctor is exhausted from working a long day, the increase in duration would allow him enough time to get some much needed rest so he can perform the operation under the best possible circumstances. Experiments have been conducted that studied the effects of preserving excised hearts by adding several compounds to the media in which the organ is being stored. The most successful of these compounds are pyruvate and a pyruvate containing compound known as perfluoroperhydrophenanthrene-egg yolk phospholipid (APE-LM). It was determined that adding pyruvate to the media improved postpreservation cardiac function while adding glucose had little or no effect. To test the function of these two intermediates, rabbit hearts were excised and preserved for an average of 24.5 1 0.2 hours on a preservation apparatus before they were transplanted back into a recipient rabbit. While attached to the preservation apparatus, samples of the media output of the heart were taken every 2 hours and were assayed for their content. If the compound

Free Essays on Poverty And Unemployment

â€Å"Poverty is produced by circumstances, not individuals.† (Fincher and Wulff, 1998) The expansion of international poverty and unemployment in the world over the last few decades has been associated with the onset of rapid growth of the capitalist market. Economic crisis or boom assists in the growth of the so-called ‘poverty sector’(James, 2002), leading to unemployment and social unrest. When comparing the poverty and unemployment within countries such as Australia and Indonesia, several distinctions can be made of the various extent of these problems. For one, Australia is classified as a ‘First World’ country, whilst Indonesia experiences the poverty of the ‘South’ or the ‘Third World’. Consequently, this produces various measurements of poverty in each of these countries and also indicates the definition of poverty in Australia and Indonesia. Other differences between the situations of poverty with these neighbours are that there are various classes, education levels and different primary industries.

Qualitative Research Proposal - Essay Example This cost doesn’t account the high cost of  £27 billion due to medical expense increased during same time (4). The alarmingly current situation and it’s accelerated pace of growth has gathered massive attention to cure the menace before it gets beyond the control. There has been increased attention toward finding the reasoning behind constantly rising obesity. Exploring this would help in adjusting life style towards healthy lifestyle habits and saving country from menace before it becomes national curse. It would also be helpful, mainly, for mothers to develop healthy dietary habits in children since early age. Obesity is a measure of an excessive or abnormal fat buildup in a human body that may perhaps harm health. Obesity, measured through BMI (Body Mass Index) is a weight equal to or greater than 30; it is 5 BMI level higher than excessive weight level defined as overweight; as World Health Organization (WHO) defines (5). Citing reason of obesity, WHO states that it is an energy imbalance of calories consumed and expended by the body. It further states this imbalance is created for the reason of either excessive intake of high calorie food or less physical activity that leads to less calorie consumption (5). This research will maintain focus on first section of reason cited by WHO and would explore the impact of behavioral, socio-environmental and genetic aspects of an individual that lead to less consumed calorie than expended. Among large number of behavioral factors studied to date, this study will focus on behavioral factors that are specifically related to dietary habits. Behavioral Factors that lead to obesity has been broadly categorized into three domains in the study of 6; that are: first, excessive food taking; second, less physical activity that that leads to less calorie consumption in caparison with intake; third being excessive diet control

Acer Group Essay Example | Topics and Well Written Essays - 1000 words

Acer Group - Essay Example When Stan Shih founded the Acer group of companies in 1976 it was more than obvious that the firm was bound to take some huge strides with this celebrated founder who made news worldwide by commercialising Taiwan's initial desktop calculatorToday Acer boasts of commendable rankings in the industry by being No. 4 in the Personal Computer market, No. 3 in the market for notebooks and No. 3 as a computer manufacturer in the face of huge competitors like Sony and others. Stan is about to retire in three years and Acer has suffered a loss of $29 million in the PC industry so Stan has diverted his expertise and attention towards making the company even more competitive in order to give it a strong foundation of support after he retires. Aspire is a large brand for Acer under which they have produced a number of technological products in the world. Aspire has had problems during the development stage whereas if these problems were dealt with proficiently then this brand would have had a tru ly aspiring brand image. Acer and Stan need to focus on the leverage points namely; efficiency (economies of scale and comparative advantage globally), knowledge leverage (strategic use of human resources and ideas on a global platform) and responsiveness (to embrace local consumer demands) (Bartlett & Ghoshal; 1989).Stan must disapprove Aspire's continued development because it is important to a put a halt to further developments in order to study the current problems it's facing. The existing discrepancies must be removed in order to develop further otherwise the problems might become deep rooted and also fatal. It is important to climb the first few steps of a ladder efficiently without being in danger of falling down and getting hurt before reaching the top. Acer faced problems during the development of Aspire and these problems still exist. Acer is a large multinational operating in Asia, Europe, and America etc. Obviously, the company has regional departments in these countrie s and in order to maintain a strong brand image in the market a common goal, strategy and communication strategy are required. Acer lacks these and due this they faced problems in positioning themselves as a strong brand when it comes to Aspire. It is important for all regional offices around the world to share a similar spirit of growth, values, standards, communication strategies etc in order to take mutual decisions as a company on the whole and not just as a regional office. Aspire has a number of brand extensions and product types being sold under one brand name and the company has not been able to position each extension with a common goal or insight in mind. Aspire is known to be a very adaptable brand since it has been changed to suit the consumer demands for every different region in a different way. This has caused major brand identity problems for Acer and Aspire. The same brand under Aspire has been positioned to be a luxurious and elite brand in Singapore and the opposi te in Europe. But it also shows that Aspire is doing a good job when it comes to responsiveness in the leverage points. This has weakened the brand equity for Aspire and has resulted in brand dilution. This shows that a strong corporate culture is absent in Acer and this results in a weak brand image and positioning for any company or brand because then customers do not know how to relate with the brand. All the regional departments and offices are working on their own values and standards to fit the culture, demand or society of the region. Due to the lack of a strong organisational culture it is evident that synergism is absent and the company is leaving loopholes for failures. All these problems must be looked into and it is important for Stan and Acer to come up with a solution before approving any further developments for Aspire.

People, Organizations and Society Essay Example for Free

People, Organizations and Society Essay Most people are individually different from one another it varies from behavior, character, attitude, lifestyles and importantly the social status. We sometimes ask ourselves why are there many people who have bad traits and good traits and sometimes having diverse mood swings and frame of mind. Different theories coming from different psychiatrist and psychologist are the concrete foundation of behavioral factors. In order for us to understand the behavior of every human being, it is better to describe the two types of conditioning which involves learning process and behavior, the classical conditioning and operant conditioning. We will discuss the similarities and dissimilarities of these two types of conditioning and further relates these two to many dimensional examples of an individual’s behavior and also that of an animal pattern of behavior. Defining Classical and Operant Conditioning In order to explore the clarity of classical and operant conditioning, it is healthier to examine and define the subject from which they are strongly associated and originated which is learning. Classical and operant conditioning has several similarities on learning such as the process of extinction, unprompted recovery, stimulus conclusion, biasness and superior directive condition or secondary reinforcement. Also, it is similar because they both generate basic occurrence and phenomena which is acquisition which result in the inheritance of a behavior (SocialPC). Classical and operant conditioning are similar in some ways but they do varies in a few ways and are equally dependable method to explain and educate a person or an animal in a specific situation. Learning is any comparatively lasting transformation in behavior and manners generated by an experience (MegaEssays, 2007). These two conditioning are the two types of several theories on learning. Classical conditioning is an important type of learning which was uncovered by Ivan Pavlov, a Russian physiologist who emphasized this observable fact through his experiments on the digestive patterns in dogs (Heffner, 2004). It is a connection of one occurrence or happening with another that results in a pattern of behavior (MegaEssays, 2007). A classic example of this phenomenon is the research done by Pavlov on his dog in which he discovered a dog’s drive to produce saliva while responding to a certain stimuli, in which a reaction or spontaneous effect that was unconscious and unintentional. When he rang a bell and was offered a food to the dog, the dog recognized it and associated the food with the bell. In this case, the bell is the conditioned stimulus while food was an unconditioned stimulus. In addition, classical conditioning often linked with muscles and reflexes and instincts. It is a very important component of a training program in which we can comprehend and figure out conditioned and unconditioned stimulus or reinforcement, species exact behaviors, inducing dislike stimuli, and feelings (2007). It is significant in understanding in dealing with problems relating to fear. Another finding confirmed the thought that we build up reactions to certain stimuli that are not naturally occurring, for example when we touch a hot stove, our response is to remove our hands back from the hot stove but now some people who already experienced after getting burned tend to pull their hands back even when the stove is turned off. This lead to Pavlov’s conclusion that people tend to relate or connect one particular experience which caused a person to simplify their reaction to one stimuli into an impartial stimuli in which it is matched with. In short, a stove burner is often associated with an expression in pain like ouch and then stove is equal to burner hence, a stove is also equal to an expression like ouch (Heffner, 2004). A lot of people’s behavior these days is formed by the combination of stimuli according to Heffner. Some observations and experience like the smell of a perfume or a particular scent, a certain song and things has been paired with a specific person or group like families, friends, ex-lover, loved ones, or a particular event or happening. These connections controls and influence us to a certain extent and in fact we have been conditioned classically (Heffner, 2004). On the other hand, operant conditioning is a type of learning experience which involves on how an organism functions or operates in a particular environment, learning here takes place as a consequence of behavior. This was termed used by Skinner in explaining the results of the consequences of a particular behavior on the future incidents or happenings of that behavior (MaricopaCenter, 1999). There are four types of operant conditioning: positive reinforcement, negative reinforcement, punishment, and extinction. In order to explain it further, an example could better explore its meaning; a cat was placed inside a box which has a single exit and entrance. The box has only one button to be pressed to open the door, the cat strived to get out from the box since freedom here is reinforced. In its effort to escape, the area of the box was set off and the door opens which leads the cat to be released from the enclosed box. But this does not end the story, the experience of the cat once placed again in the box, the cat will immediately escape since the cat will immediately recall the experience last time and will once locate again the button to push. Learning from experience is the concept from the example, the cat learned from the experience through natural results and how to achieve or acquire the reinforcing freedom (Heffner, 2004). Let’s pick a broader and relevant experience in the past, several times the Philippines were colonized by different conquerors and explorers and this colonization was strongly connected with harassment, violence, sexual abuse of women, forced labor, poverty and many more. The initial reaction is to obey and follow because freedom here is not welcome. Food and water is scarce and people would rely on the given ration, in order to get that food, one must steal more food to accumulate one’s hunger. Once again, freedom is reinforced here. The people of this nation once weakened but tried to learn from their experience not to be placed in a box where freedom is impartial. They have to press a button like the cat to open the door for freedom and find the answer from that experience. It’s like every individual who naturally encountered past mistakes presumably that individual will recall that mistake when things similar to that situation happens again. Same situation for positive outcome is true where effects from that outcome you did last time will likely do that same again. Four types of operant conditioning (Heffner, 2004): Positive reinforcement: this happening is often associated to anything stimulus which strengthens the probability of a specific response which are expressed in praise or rewards. A good example is when a parent appreciated a child’s good work after they have done something positive like cleaning their own room. This will increase the possibility that the same reaction will be repeated. Negative reinforcement: this constitute on the elimination of a particular negative stimulus which is reinforcing in order to increase a response. An example of this is a nagging mother who always scolded her daughter or son to clean their house every week. After telling and complaining to their friends about the distressing words it counters and lastly performs the chore and eventually stopped the nagging. Punishment: this refers to adding together something induced dislike in order to lessen a behavior. Disciplining by way of spanking is the most common example of a specific misconduct. Punishment is disliked and will surely avoid it by behaving in a good manner. Extinction: When something is removed so as to lessen a behavior is called extinction. Example is when a child owns and addicted to a teddy bear which irritates a child’s asthma will likely to react initially but for the parents it is positive that the teddy bear be removed to decrease levels of negative outcome like grasping for air when sniffed a fabric or cotton from the teddy bear. Relevance and application to business sector: In the business sector these two types of learning method has a significant advantage and guarantee positive outcome in the future. Less emphasis on classical conditioning, the operant conditioning is more likely to apply in designing a training course or let’s say changing an employee from a specific behavior in the workplace. Since operant conditioning involves on how it operates in a certain environment and learning takes place as a result of the behavior, we will be more focused on the positive reinforcement which is a very good tool for improving an employee on its negative behavior in the workplace. However, there are times that positive reinforcement would not work so other method can be used such as negative reinforcement, punishment and extinction. Let’s take a common example of a negative manner seen in an employee like tardiness, sleeping, delayed reports, absenteeism, abuse of policies and many other unnecessary manners. In order to alleviate and ease the tension in the way it is practiced, the management can formulate a positive reinforcement like giving importance to the people who always come on time and are constantly prompt in coming to the office. This can be done through rewards and additional compensation and acknowledgement. While those employees who are intensively late all the time despite of warnings from the management should be more reprimanded and disciplined by giving them penalty. The concept of punishment is generated here to reduce tardiness and eventually employees will dislike the penalty or punishment and surely avoid the misconduct by coming on time and perform their duties in a timely manner. Negative reinforcement may or may not work as a method to prevent misconduct in a workplace since it dismays or disappoints an employee because it’s sometimes involves verbal reinforcement to decrease negative stimulus, this is more applicable to a parent-child relationship but for employees, it’s not lasting and holistic and possibly produce a unprincipled outcome.

John Bergers Ways of Knowing Essay example -- Ways of Knowing Essays

In his first essay of Ways of Seeing, John Berger claims that all power, authority, and meaning that was once held by an original work of art has been lost through the mass reproduction of these works that has occurred in recent years. He writes of an entirely bogus religiosity (116-117) that surrounds these art objects and that the meaning of the original work no longer lies in what it uniquely says but in what it uniquely is (117). He claims that because of reproduction, the art of the past no longer exists as it once did (127). Obviously, something created hundreds of years ago is not the same as it once was, but the distribution of art and music to the general public has had a positive effect on society rather than a negative one. Works of art have even more meaning than they had when first created through the interpretations offered them by generations of critics and artists. Fresh new sources have been given the ability to offer their insight and abilities into art, creating en tire new genres of art, music, theatre, and the like. It has allowed for a truer search for knowledge than was ever possible before. And ultimately, the search to find the true meaning of art and of the ideas of the artists forms a true sense of religiosity, which gives passion and meaning to the lives of groups stretching far beyond the cultural elite. An example that Berger uses to illustrate his points is that of a filmmaker who uses images in film. Berger states that Awhen a painting is put to use, its meaning is either modified or totally changed (120) and when a painting is reproduced by a film camera it inevitably becomes material for the film-maker’s argument (121). He concludes from this that only the original painting holds integrity while the image shown on film is an expression of the film-maker’s argument. However, this idea furthers the meaning of the painting by adding connotations to the one the artist intended. When an artist creates a painting, he or she hopes for this work to be critiqued and interpreted by others. These critiques and interpretations add to the full meaning of the work for everyone seeing it afterwards. Thus, we undermine the true meaning of the work by saying it can only mean what the artist originally meant it to, because this is something we can never know. The viewer should deter mine the value and meaning of each painting. The paintings... ...nable future of what we could have, and is empowered by envy. Ultimately, Berger claims that the sublime quality of art has been transformed into simple information through reproduction, when in reality; this type of culture has always been about information. Through reproduction, we can strive for a truer sense of information, in reaching the true meaning of art rather than using the information for a sign of status. It is no longer a matter just of knowing of art and culture; it is a matter of knowing about it. The available levels of information have increased, and have allowed more people to experience a true sense of religiosity toward art, music, and other culture than was ever previously possible. Rather than ruining the integrity and credibility of culture by offering it to the masses, it remains a symbol of status and power for those who wish to use it as such, and has become a source for passion and knowledge for others. It has also allowed new ideas and insight to thes e fields from non-traditional sources. Finally, instead of taking away from the meaning of original works of art, reproduction has added to it.

Transit of venus

The play Transit of Venus was authored by Maureen Hunter. The storyline was based on the life of an 18th century French astronomer named Guillaume le Gentil de la Galaisià ¨re. As an astronomer Le Gentil attempted to chart the crossing of the planet Venus across the sun and the Earth, hence the title, Transit of Venus.Le Gentil was obsessed in charting the transit of Venus across the sun to the point that he neglected his fiancà ©e, Celeste. His obsession took him away from home for long periods of time. On one of his absences, Celeste thought that he died on his journey and thus, turned her love to Le Gentil’s assistant, Demarais.Upon Le Gentil’s return, after his unsuccessful journey, he tried to win back Celeste but failed. Thus, the play showed Le Gentil’s unsuccessful attempt in love – his love for his occupation as well as his love for his fiancà ©e.We could see signs of symbolisms used throughout the play. For instance, the opening of the play wa s accompanied by a storm which reflects the character’s obsession and incessant desire which is very much evident all throughout the play.While we know that the main character of the story, Le Gentil needs love, he was not able to know just how much he needs it until it was too late as he was blinded by the frenzy of mapping Venus’ journey across the sun, an obsession quite common among astronomers during the 18th century.It is also evident that Celeste desires Le Gentil and was even willing to wait for him for long periods of time. In the end, Celeste learned to let go of her feelings for Le Gentil as she found the love which she seeks on Le Gentil’s assistant, Demarais.While the transit of Venus is often associated with science, the play itself focused more on how Venus was used to symbolize love. The use of the planet Venus to symbolize love is not surprising as Venus is also the Roman counterpart of the Greek’s goddess of love and beauty, Aphrodite. T hroughout the play, we could see how love (Venus) made its way (transit) across the characters of the story.The opera also showed us different faces of love. For instance, while we know that Le Gentil’s love for his fiancà ©e is real we could also see that it was outweighed by his devotion to serve God.The story revealed that Le Gentil’s obsession was driven by his need to serve God. It was not uncommon during Le Gentil’s time for scientists to correlate science with religion and there are many people who believed that by mapping the transit of Venus across the sun they would be able to prove that science could coexist with religion.Le Gentil was greatly driven by the need to map the transit of Venus to the point that he was not able to see what is really important, his love for his fiancà ©e, Celeste.As I have already mentioned earlier, Le Gentil failed to map the transit of Venus and at the same time he also failed to pursue his love for Celeste. We could se e that this was symbolized by the fact that his attempt to map the transit of Venus failed as clouds blurred his vision and disabled him from witnessing Venus’ transit.The opera also made use of expressionism. Expressionism gives emphasis on the characters’ divine awakening, pain, and suffering. In watching the play, the audience would be drawn to the sufferings of the characters.Expressionism is evident on Le Gentil’s desire to fulfill his spiritual hunger which he believed could only be done by serving God. His journey to serve God, to unite science with religion, led him to a path filled with pain and suffering as he did not succeed in his journey and at the same time lost the love of his fiancà ©e.Expressionism is also present on Le Gentil’s relationship with Celeste in that at first, Celeste was willing to sacrifice for Le Gentil. For love, Celeste was willing to wait until Le Gentil was done with his journey. While it pained her that Le Gentil†™s work is more important than her, she endured the pain and silently waited for her fiancà ©e’s return.Women, during Celeste’s time, were not exactly on the same footing with men. This is evident on how Celeste’s character showed how she allowed her fiancà ©e to subjugate her own desire. However, at the end of the play we saw how their positions were reversed as Celeste rejected Le Gentil’s love.

Domestic Polices of Johnson and Eisenhower Essay

The decades of 1950s and early 60s were periods of unprecedented affluence, prosperity and economic growth for USA, at scales that is difficult to match by any other country in human history. Years of persistent industrial growth, technological advances, and a full-time developed economy during the Second World War set the platform for USA to experience continued improvements in its industrial outputs, living standards, individual income, business and commercial profits, and infrastructural and capital growth. With its GDP and GNP repeatedly touching new record heights, USA had undisputedly become world’s richest behemoth. However, amidst this spectacular mantle of prosperity, there remained large patches of poverty, racial discriminations, unemployment and inequality that did not conform to high level of affluence generally attained through out the nation. To bridge this yawning gap, President Johnson launched the concept of ‘Great Society’ with aim to bring equality and justice in US and distribute fruits of growth and prosperity to every citizen. Policies and Programs of ‘Great Society’ The landslide victory of Lyndon Johnson in 1964 general election gave him suitable platform introduce a series of legislations concerning education, healthcare, environmental protection, consumer rights, regional and urban development, civil rights, employment opportunities, social welfare and income supplement programs, as part of his vision towards the great society. As Johnson himself belonged to middle class family, his ideas were well shaped and oriented towards the exact framework that he wished to create. Pursuant to this vision he proceeded to introduce a number of legislations that included, Food Stamp legislation, Civil Rights Acts, Economic Opportunity Act, Mass Transport Program, Public Work and Employment Act, and Medical Health Car, Social Support, and Education Programs. The notable programs under Johnson’s ‘Great Society’ were 1. Income Assistance: Under the Income Assistance program, financial coverage and assistance were provided to people to enable them to support themselves and become self-dependent. People were counseled, advices and encouraged to strive to meet their own requirements, under government aegis. 2. Education and training: Johnson was of firm view that education and training had crucial role in uplift deprived people to general levels of prosperity and affluence, providing tools and paths to break the vicious cycle of poverty and seclusion. Therefore, he put special emphasis on providing equal educational opportunities to economically deprived children. In the ‘Great Society’ Elementary and Secondary Education Act of 1965, special provisions were included to provide financial help, services and required assistance to schooling agencies and boards covering areas with economically disadvantaged families. Further, provisions were instituted that provided direct financial help and support to individual disadvantaged students. A number of training programs were launched in semi urban and rural areas to provide work exposure, work related training and vocational training to people, to enable them to earn and break free of poverty. 3. Healthcare and Medicare Programs: Recognizing the requirement of healthcare for all, an integral part of ‘Great Society’ vision was to provide medical care for elder and poor people, who are unable to look after themselves. The Social Security Act of 1965 and 66 ensured health care and medical treatment for people belonging to all age groups. 4. Housing: A rapidly emerging urban America required houses to support the millions that came to cities to full fill their dreams. Concurrent were the problems of providing secure shelter to thousands homeless poor, left stranded on streets in inclement conditions. Therefore through Housing and Urban Development Act of 1968 one the one hand government targeted construction of 26 million additional rehabilitation units and on other provided for easy flow of real estate credit, liberalized loan market, expanded public housing fund, and low installments to enable people in low and middle income groups to own houses. 5. Environment: One of significant achievements of Great Society vision was launching policies to make environment as free of pollutants and chemicals as possible, and thus imitating the drive towards environmental awareness. Armed with a number of acts and legislations such as Clear Air, Water Quality and Clean Water Restoration Acts and Amendments, Wilderness Act of 1964, Wild and Scenic Rivers Act of 1968, Land and Water Conservation Act of 1965, Motor Vehicle Air Pollution Control Act of 1965 etc, Johnson tried to create a social culture that is aware of its responsibilities in protecting environment. Differences with Eisenhower People, and especially poor oriented polices launched by Johnson stood in contrast with the generally industrial and business focused programs adopted by Eisenhower in his regime from 1953-61. During the Presidency of Eisenhower, social welfare programs had taken backstage before large-scale industrial, infrastructural, and military programs. Although the entire nation as an entity move ahead, serious gaps had remained in its fabrics that Johnson tried to cover with his welfare programs under ‘Great Society’

Aging as a Genetic Process in essays

Aging as a Genetic Process in essays There are several theories on aging in humans due to genetics. There are four main theories involving genetics and these are the wear and tear theory, the free radical theory, cross-linking theory and somatic mutation theory. Aging is defined as The process of growing old or maturing. Most of these theories follow that though some sort of damage to the DNA other parts of the cell, the cell dies with leads to the human body to age. These theories are not all proved to be correct some people believe that some are better then others as there is no known reason for aging in genetics. The cross-linked theory of aging, this theory follows the basis of that with age, the proteins in our body, our DNA and other structural molecules in our cells develop over time inappropriate attachments or a more appropriate name cross-linked. These bonds can inhibit protein enzymes breaking them down so these damaged (cross-linked) proteins stick around. As they are in the cell and cannot be broken down, they can then cause problems and therefore they can lead to cell damage, which can lead to aging. For example cross-linking of the protein collagen ahs been shown to cause wrinkles which is a common sign of aging. If cross-linking occurs in the DNA, then when the DNA is used to produce proteins and other things it will produce the wrong ones or be deleted which will cause aging too. This theory however is not very favoured as the direct physical (experimental) evidence at this time is not very conclusive that this is the primary cause of aging. The wear and tear theory of aging suggests however that the due to years of damage to cells, tissues and organs, which wears them out and eventually, kills them. This can be especially be seen in the liver fro damage due to alcohol. On a DNA level, it sustains damage from a wide range of toxins, ultraviolet light and radiation. DNA can be repaired but not all can be repaired or sometimes the repair c ...

The primary problem with ravish is that it has romantic connotations: it means not only to rape but also to fill with ecstasy or delight. The latter sense renders the word unfit for acting as a technical or legal equivalent of rape, The term describing the act should evoke outrage; it should not be a romantic abstraction, as ravish is.Still, the word ravishing ( captivating, enchanting) is generally considered a perfectly good and complimentary adjective.(Bryan A. Garner, Garners Modern American Usage, Oxford University Press, 2003)Both words refer to powerful and usually destructive forces. Ravage is used when destruction is spread over a wide area by war or other overwhelming forces: ravaged by inflation / tribal warfare / acid rain.

Detailed explanations of the IOT (internet of things) and implications technology - Essay Example This will be made possible through the increased connectivity between the physical items and the virtual world (Mattern & Floerkemeier, 2010). The Internet of Things is not created by a single novel technology. However, it is made up of a variety of technical developments that create the capacity to bridge the existing gap between virtual and physical world. The capacities that would be created include communication and cooperation, addressability, identification, sensing, actuation, embedded information processing, localization and user interfaces (Mattern & Floerkemeier, 2010). The objects through communication and cooperation would have the capabilities to network between each other as well as with the internet sources, and to update their state using data and services. In addressability, the objects have the capacity to be remotely configured and interrogated through effective location and address through discovery. The physical objects will also be uniquely identified. The optically readable bar codes and the Near Field Communication are just a few of the technologies that incapacitate passive objects that lack inbuilt energy resources to be identifiable. With sensing, the objects will be or are equipped with sensors enabling them to collect data, record and interpret it accordingly then forward or reacts to it. They also have actuators for environment manipulation. They have microcontrollers, processors, in addition to storage capacities. By localization, the objects are conscious of their physical locations or better still can be located. With the user interfaces, the objects are able to effectively communicate with people in appropriate and relevant manner. The concept is premised on the trends witnessed towards the end of the 20th century, where there exist gradual advances in communication and information technology, as well as in microelectronics. These changes
