Scienece Column - Article Example This is all about thermodynamics. In essence, thermodynamics involves the examination of the internal motions of various body mechanisms; or rather it’s a subfield of natural science that involves heat and its relationship to various forms of energy and work. Therefore, heat becomes an integral and essential component of thermodynamics. Virtually, most of the substances that people encounter with in their day to day life consist of body systems of one kind or the other, that is, they either fall under solids, liquids, gases or even light. It is therefore, unsurprising that thermodynamics is a field in physics that comprises exceptional wide variety of applicability. There are numerous thermodynamic experiments used to demonstrate the movement of energy from one substance to another as a result of varying of temperature. This column shall study two of the four forms of thermodynamic experiments discussed in the past few weeks. One of the study experiment that this column shall detail on is 'the meaning of heat and this shall be illustrated using the calorimeter experiment. The second form of thermodynamic experiment to be studied is the Statistical physics lab and this will be based on the concept of thermal energy of randomly moving molecules with heat used as the mode of transfer. Meaning of heat Heat is defined as a form of energy, sometimes referred as thermal energy capable of passing through an object of high temperature to an object with low temperature. The flow of heat is essentially measured using a device known as calorimeter. This device operates in such a way that it is insulated to minimize the loss of heat to the surrounding. Within some essential temperature variance, it is easy to understand the hotness or coldness of something by simply touching it. However, it is unreliable if you place one of your hands in cold water, and the other into hot water, then you plunge both into warm water. You will note the difference, one hand will detect that the water is hot, while the other will experience some cold. In other aspects, when something is too hot to hold or even touch, we usually get an impression of how hot the substance is by approaching it and detecting the radiant heat it emits. if there is an increase in temperature, the substance glows hot. The major problem with such subjective feelings of heat is that, they are different for various persons. If two hands transmit different messages pertaining the hotness or coldness of a substance, how about a group of people? Obviously, they will report varied responses. In illustrating the flow of heat, an experiment was set up, whereby a pan of water was placed on a hot glowing fire and the temperature observed over time. It was noted that, their was steady increase in time, reflecting the transfer of heat from the fire, up to the moment the water started boiling, whereby the temperature remained constant for a long period. The steam emitted had same temperatures as the bo iling water. So, what actually happened to the heat transferred from the fire to the pan of water? It was found out that, heat was needed to change the form of water from the liquid to the gaseous form/steam. In-fact, a high amount of heat is required to change the state of water to steam form, approximately 540 calories per gram. This is far much

Death Penalty - Justified Essay -- Argumentative Persuasive Papers

Death Penalty - Justified There are many problems facing our criminal justice system today. Some of the more important ones are overcrowded jails, the increasing murder rate, and keeping tax payers content. In light of these problems, I think the death penalty is our best and most reasonable solution because it is a highly effective deterrent to murder. And, tax payers would be pleased to know that their hard-earned tax dollars are not being wasted on supporting incorrigible criminals who are menaces to society. In addition, they would not be forced to fund the development of new penitentiaries in order to make room for the growing number of inmates in our already overcrowded jails. Moreover, the death penalty would serve to curb the growth of future crimes and consequently the number of inmates would also be reduced. Thus, overcrowding in federal and state penitentiaries would be eliminated. In this essay, I will discuss these ideas and prove why capital punishment is the best viable solutio n to the problems plaguing our criminal justice system. Capital punishment could solve our problem with the increasing murder rate because it serves a highly effective deterrent. â€Å"The death penalty deters murder by putting the fear of death into would be killers. A person is less likely to do something, if he or she thinks that harm will come to him† (Studyworld 1). This fear of death is the key to reducing the murder rate. Frank G. Carrington informs us that Louis Joseph Turck..., an ex-convict with a felony record dating from 1941, was arrested May 20, 1961 for robbery. He had used guns in prior robberies in other states but only pretended to be carrying a gun in the robbery here [Cal... ...ng tax payers, and the other problems facing out criminal justice system. As we have seen, it can serve as a deterrent and reduce the murder rate. In addition, the death penalty would fee up space in overcrowded state and federal prisons. Moreover, it satisfies tax payers because it requires less tax money and can eliminate the need for additional prisons. Hence, capital punishment should be instituted everywhere.

Disease Trends and the Delivery of Health Care Servies Essay

INTRODUCTION Americans use health care services every day, and they use them for a number of different reasons. Whether it is for preventing or curing illness, mending broken bones, delivering infants, or perhaps long term care in a nursing home there has been and will always continue to be a consistent need for the health care industry. According to an article published by the National Center for Health Care Statistics, there are a number of different factors that determine how much health care people use, the various types of care that they use, and the timing of care that they seek (Bernstein, Hing, Moss, Allen, Siller and Tiggle, 2003). These factors could include many different variables; however, for the purpose of this paper we will discuss how trends such as the aging population, and the growing rate of obesity in America are likely to influence the delivery of health care services in the future. THE AGINING POPULATION The population of the United States on April 1, 2010 was 308.7 million people. This is according to an article regarding the 2010 Census report (Howden & Meyer, 2011). In the same article the age composition of the population is broken down. It shows that those aged infant to 18 accounted for 24.0 percent of the country’s population. In addition citizens between the ages of 18 and 44 represented 36.5 percent, and those 45 to 64 made up 26.4 percent of the population. Finally, individuals aged 65 or older accounted for 13.0 percent of the United States population (Howden & Meyer, 2011). These numbers are expected to change significantly over the next few decades. More specifically, the older population which consists of  individuals 65 or older is expected to grow rapidly. This expected growth is largely in part due to the generation known as the baby boomers. This concept is supported in another article published by the U.S. Census Bureau. It states, Between 2010 and 2050, the United States is projected to experience rapid growth in its older population. In 2050, the number of Americans aged 65 and older is projected to be 88.5 million, more than double its projected population of 40.2 million in 2010. The baby boomers are largely responsible for this increase in the older population, as they will begin crossing into this category in 2011. (Vincent & Velkoff, 2010, para 2). In addition, there are other factors that support the population growing older. These factors include a decline in fertility rates, and an increase in the age of average life expectancy. It goes without saying that older generations have different medical needs then do younger generation. Furthermore, as the populations grows older there will be a greater demand for health care services. According to a summary report published by the University of Albany it is estimated that 84 percent of people 65 or older are likely to suffer from at least one chronic medical condition. Such conditions include cancer, heart disease and diabetes to name a few (2006). Along with rising health care needs there will be a greater demand for prescription medications as well. In conjunction with these factors the need for long term care facilities will grow also. As we know already when there is a demand for something there must also be an adequate supply. There is great concern that as the population ages it is probable that the supply of health care services may not be enough. In the same summary published by the University of Albany it states, The expected growth of the older adult pop ulation in the U.S. over the next 50 years will have an unprecedented impact on the U.S. health care system, especially in terms of supply and demand for health care workers. The supply of health care workers may decrease as they age and large numbers retire and/or reduce their working hours. At the same time, older adults consume a disproportionately large share of American health care services, so the demand for health services will grow. The aging population will also affect the nature of the skills and services the health care workforce must be equipped to provide, and the settings in which this care is provided.  (2006, page 2) In addition, there will not just be a greater need for health care professionals such as psycians, nurses, lab technicians and more. There will also be a large necessity for advancements in health care technologies and facilities. We know that there is nothing that can be done to stop the process of aging itself; however, there are measures that can be taken to reduce the health complications that are related to aging. According to the Centers for Disease Control and Prevention, a few opportunities to improve health and quality of life in older generations include promoting healthy lifestyle choices such as quitting smoking, and increasing the use of preventative services (2011). THE GROWING RATE OF OBESITY Obesity is a disease that is associated with having an excess amount of body fat. It is condition that has been linked to a number of different medical issues including diabetes, high blood pressure, high cholesterol, and stroke to name a few. As reported by the Centers for Disease Control and Prevention, over one-third of the population is considered obese costing the United States an estimated $147 billion in 2008 (2013). Although the numbers are already astonishing they are only expected to grow in the future. An article featured in the American Medical News predicts that if the obesity trends continue to rise by 2030 an estimated 50 percent of America’s men and 45 to 52 percent of its women will be obese (Henry, 2011). There are many factors that contribute to the growing trend of obesity. According to the U.S. Department of Health and Human Services, the environment around us does not support healthy lifestyle habits (2012). This is because we live in a world with advance d technologies and conveniences. With busy schedules it is often easy for people to give in to fast food or microwave dinners because they are quick and easy. It can also be difficult for people to get physical exercise because many neighborhoods around the country lack safe places for recreation, or affordable gyms (The U.S. Department of Health and Human Services, 2012). A few different demographic factors linked to the obesity trend include age, sex, and race. As mentioned previously, Americans spent as estimated $147 billion for health care services in 2008. This number is expected to grow substantially  over time. One author wrote that the cost of obesity is expected to reach $344 billion by the year 2018 (Thorpe, n.d.). These numbers are outrages. In addition to the rising health care cost that stems from obesity we have to be concerned about the health complications that can come with the disease. Obesity has been linked to an insane number of health conditions including type II diabetes, high blood pressure, heart disease, stroke, osteoarthritis, some forms of cancer, sleep apnea and many more. There are steps that can be taken to prevent obesity, and the health issues that are associated with it. Eating healthy is vital, and not always as easy as it sounds. It can be so very easy to fall into food traps but we should focus our time and energ y towards foods that are rich in nutrients and low in calories. These foods include lean meats and proteins, fruits and vegetables, and whole grains. It is also important to exercise on a regular basis. Exercises such as walking, swimming, or running are excellent. In addition, reversing the obesity epidemic in America is going to require a community effort. Schools, places of business, and government agencies should all be involved in this mission. CONCLUSION As our population ages, and obesity rates rise in America there is no doubt that the health care industry will need to adapt. These issues will require many advancements is medical technology, as well as a larger supplies of health care professionals including doctors, nurses, mental health providers, lab technicians, long term care providers, and administrators. The list could go on and on. Therefore, in the next few decades it will be important for the industry to recruit, and adequately train new health care professionals as the baby boomer population nears retirement. Moving forward, it will also be important for the community, and not just the health care world, to implement new ways to encourage preventative care. This will require many different organizations to become involved, most especially schools because the key to prevention is education. If the younger generations are taught the healthy way to live, and if more parents lead by example the future of this country would i n turn be much more healthy. The world of health care is ever changing, and there are many different  trends that affect it. As the future rolls forward it will be most interesting to see how health care professionals adapt to each trend. REFERNCES Bernstein, A. B., Hing, E., Moss, A. J., Allen K.

The American Film Industry Essay - 3364 Words

The American Film Industry Why is the Film Industry one of the largest and fastest growing industries in the world? Simple. People like entertainment. Movies are entertainment. Movies are like books, only theyre visual. People like seeing other people cast in roles, and playing out a story. Why not turn to plays instead, you ask? Movies give people the actors and the stories, along with background music, special effects, and overall satisfaction within a 2 hour period of time. Movies can also take you to a physical state that theatre can not. They take you to real physical locations instead of just a cardboard stages. Its the same reason people like television so much. The birth of cinema came in the late 1800s. One of†¦show more content†¦In 1909 the first movie studio was started - Universal Studios. The ten year peiod of 1920-1930 was the period between the end of the Great War and the Stock Market Crash. Film theaters and studios were not initially affected in this decade by the crash. Films really blossomed in the 1920s, expanding upon the foundations of film from earlier years. Some of the best artists from European film-making circles were imported to Hollywood and adapted there. The basic pattern of the film industry, and its economic organization, was established in the 1920s - the studio system was essentially born in the second decade of the century. With films, came a need for protection, and ratings. The Motion Picture Association of America (MPAA) acted domestically as the voice and advocate of seven of the largest producers and distributors of filmed entertainment. MPAAs counterpart, the Motion Picture Association (MPA) served the same purpose on an international basis. Founded in 1922 as the trade association for the American film industry, the MPAA has broadened its authorization over the years to reflect the diversity of the expanding motion picture industry.
