Diabetes Essay -- essays research papers

Diabetes Mellitus is a serious disease shared by 16 million Americans (PharmInfoNet1). It is a disease characterized by a failure of the pancreas to produce enough if any insulin. Insulin is the chemical in the body that turns sugar into usable energy. â€Å"While it is treatable, diabetes is still a killer. The fourth leading cause of death in America, diabetes claims an estimated 178,000 lives each year. So the treatment is aimed at holding the disease in check, reversing it where possible, and preventing complications† (Hingley 33). Due to the life threatening nature of diabetes, the necessity of controlling it is absolutely imperative. Philip Cryer, M.D., president of the American Diabetes Association and a professor at Washington University School of Medicine in St. Louis, believes that people don’t understand how much of a problem diabetes can be. He says, â€Å"Diabetes is an increasingly common, potentially devastating, treatable yet incurable, lifelong diseas e. It’s the leading cause of blindness in working aged adults, the most common cause of kidney failure leading to dialysis or transplants, and is the leading cause of amputations† (Hingley 33).   Ã‚  Ã‚  Ã‚  Ã‚  For decades since its discovery in 1920, injectable insulin has been the standard treatment for diabetes. In fact, it is the only treatment for insulin-dependent diabetes. And the standard method of administering it has remained injection with a syringe. But in recent years, there have been enormous advances made in the development of new and better ways to administer insulin. By far the best, most effective way to administer insulin that exists today – the way that most closely mimics the way the human body releases insulin into the bloodstream – is no longer through injection with a syringe, but rather, through the insulin pump.   Ã‚  Ã‚  Ã‚  Ã‚   To understand diabetes, it is important to first understand how a non-diabetic body functions to process the normal presence of glucose in the bloodstream. Everything a person consumes is converted to glucose, at different rates depending on exactly what was consumed, and ultimately deposited into the bloodstream. There it circulates, waiting to be called to action. When the body perceives that energy is running low, glucose in the bloodstream is ushered into the various cells of the body where it is converted into energy as n... ...ts today.

What Is Software Defined Radio?

What is Software Defined Radio? With the exponential growth in the ways and means by which people need to communicate – data communications, voice communications, video communications, broadcast messaging, command and control communications, emergency response communications, etc. – modifying radio devices easily and cost-effectively has become business critical. Software defined radio (SDR) technology brings the flexibility, cost efficiency and power to drive communications forward, with wide-reaching benefits realized by service providers and product developers through to end users.Defination of SDR Simply put Software Defined Radio is defined as : â€Å"Radio in which some or all of the physical layer functions are software defined† A radio is any kind of device that wirelessly transmits or receives signals in the radio frequency (RF) part of the electromagnetic spectrum to facilitate the transfer of information. In today's world, radios exist in a multitude o f items such as cell phones, computers, car door openers, vehicles, and televisions.SDR defines a collection of hardware and software technologies where some or all of the radio’s operating functions (also referred to as physical layer processing) are implemented through modifiable software or firmware operating on programmable processing technologies. Benefits of SDR For Radio Equipment Manufacturers and System Integrators, SDR Enables: 1. A family of radio â€Å"products† to be implemented using a common platform architecture, allowing new products to be more quickly introduced into the market. 2. Software to be reused across radio â€Å"products†, reducing development costs dramatically. . Over-the-air or other remote reprogramming, allowing â€Å"bug fixes† to occur while a radio is in service, thus reducing the time and costs associated with operation and maintenance. For End Users – from business travelers to soldiers on the battlefield, SDR technology aims to: 1. Reduce costs in providing end-users with access to ubiquitous wireless communications – enabling them to communicate with whomever they need, whenever they need to and in whatever manner is appropriate.

Essay on Social Inequality in the United States - 701 Words

Social Inequality in the United States There is a high degree of social inequality within the United States. Of most modern industrial countries, the United Stated has some of the richest and some of the poorest people to be found. That fact is very disturbing, however, explains why much of the inequality exists in the US. In the following essay I will explain to you about the inequality in our country and why it occurs, based on the theoretical perspectives of a functionalist, conflict theorist, and social interationist. Functionalist argue that stratification is necessary and beneficial to a society to ensure the highest qualified individuals will fill the best societal positions. Inequality in the†¦show more content†¦The functionalist feels that social inequality is necessary for the society to work as a whole. According to the conflict theory on social stratification, those in the upper levels of a stratification structure hold a monopoly over the communitys or societys desirables and the use of their monopo ly to dominate others. In Imagine a County, it reads about the US school systems that are rigged in favor of the already-privleged, with the lower caste children tracked by race and income into deficient and demoralizing classrooms. Public schools budgets are determined by property taxes, allowing the higher income districts to spend more money than the lower income districts. When talking about conflict theory, there are the bourgeoisie and the proletariats, which in this instance are the wealthy and the less fortunate. The wealthy schools are packed with well stocked libraries, and the poor schools are lucky to have up to date books. This not only causes conflict between the two classes, but a high level of inequality as well. These elements of this society tend to contribute to the instability and inequality of this society. Symbolic Interactionism suggest that humans define situations upon past experiences, and then act on those definitions. The legitimacy of the stratificatio n structure is established and perpetuated through teaching beliefs to the young and enforcing those beliefs.
