Electric Vehicles - Term Paper Example Such finite supplies necessitate current technology and development to be concentric upon finding alternate means of locomotion that service the needs of current and future human populations. One of the most relevant alternatives that currently exists within the field of transportation science is of course the prospect of the electric vehicle. Although the technology to produce such vehicles dates back to prior to the Second World War, it is only recently that the forces of environmental preservation, global warming, and the rising cost and ultimate limitations to fossil fuels have brought this technology to the forefront yet again. Yet although electric vehicles offer a great deal of promise, the fundamental scientific proof of thermodynamics must be applied in order for the researcher/reader to understand why electric vehicles have not caught on to a more profound and/or successful degree. As such, the following analysis will consider the second law of thermodynamics as it relates to electric vehicles as well as elucidating a level of discussion as to several other drawbacks that electric vehicles currently exhibit (Tai-Hoon et al. 59). Naturally, such shortcomings should not be seen as a fatal blow to electric vehicles now and in the future; rather, it will only help to delineate why the current technology is not sufficient to provide a fundamental shift in the market and remedy to the transportation pressures that currently force the system to rely upon fossil fuels. As a matter of clarity, the second law of thermodynamics states that entropy of an isolated system cannot decrease. This is due to the fact that isolated systems continual move towards a level of thermodynamic equilibrium; also known as a state of maximum entropy. This has also been used to express why perpetual motion machines of any type are impossible (Zhang et al. 517). Many of the current design strategies and business plans surrounding the production and development of electric vehicles i s of the false belief that the creation of an effective fuel cell will herald the beginning of the end for the concept of entropy. However, rather than this being taken seriously as a legitimate and proven scientific theory, this is in fact merely a sound bite that many investors and producers of electric vehicles have latched onto; devoid of any grounding in the reality of science (Gonzalez-Romera et al. 9317). Due to the fact that the second law of thermodynamics does not allow for any self contained system to perpetuate itself indefinitely without the consumption of resources to continue such a process as it was designed, no matter how efficient a fuel cell or alternative technology is released with relation to the electronic vehicle, it is ultimately impossible to meet the expectations of many individuals within the market (Abu-Siada et al. 17). Another problematic issue that exists with regards to the laws of thermodynamics and the electric car is the lack of understanding that many within society integrate with regards to where the energy comes from that powers these aforementioned electric vehicles. Although the emphasis upon being â€Å"green† and environmentally responsible is a step in a positive direction for all those within society that seek to

Book Report on The Immortal Life of Henretta Lacks Essay

Book Report on The Immortal Life of Henretta Lacks - Essay Example The cells that belong to Henrietta Lacks are known by the code name HeLa. When Henrietta died in 1951 because of the cervix cancer, cells from her cancerous tumor were cultured by George Otto Gey and create immortal cell line for medical research. HeLa were the first human cells vigorous enough to survive outside the human body, have been productive enough, increased and multiply in test tubes long after her death. Henrietta’s family had no idea that the said cells were used according to this purpose until during the year 1970’s where the medical companies merchandised the cells for profit purposes. Rebecca Skloot describes the HeLa cells as undergoing mitosis which defines in the normal cells as dividing into two. Currently, there are over 50 metric tons of the said cells that are still booming, and flourishing. This New York Times best sellers takes the readers to an extra ordinary journey from the John Hopkins Hospital in the 1950’s to winning several awards i ncluding 2010 Chicago Tribune Heartland Prize for non fiction, 2010 Wellcome Trust Book Prize, 2011 Audie award, and has been featured on over 60 critics’ best of the year list. ... The Primary Characters of the Book Henrietta Lacks is the main characters of the book. The book tells her story from her being a tobacco farmer down to the bed of the hospital of John Hopkins, from her death to the immortality of her cancer cells. One of the main characters to be considered in the book is the family of Henrietta, they could hardly understand why despite the death of their loved ones, Henrietta’s cells still exists and live. However, the love for the family remains strong and the search for justice and to unravel the truth continues. Implications of the Ethical Leadership and Cultural Competence During the time wherein Henrietta Lacks hospitalized at John Hopkins hospital, there is no Institutional Review Boards (IRBs) to govern and approve their research protocols during that time. Even the people who are discriminated and belong to the black race are illiterate about the procedures in relations to the rights of the patient while in the premise of the hospital . Giving the comparison in the evolution of the biomedical evolution during the 1940’s-1970’s between the dilemmas that facing us today, during the time of the HeLa cell dissemination, informed consent was the main point of debate, whereas at the present, two core elements of ethics in biomedical research: privacy and managing conflicts of interest. Recently, the HIPAA privacy rule was enacted. It is a security standards and safeguards for the use of electronic health care information as well as the creation of the privacy standards for protected health information. However, the rules claim equality among all members of the community regardless of the race. How Various Aspect of the Seven Revolution Woven into the Book In the
