Diabetes Contents Introduction Overview of Diabetes Type I What is diabetes type I Health implications of diabetes type I Physical Activity What is physical activity? Why do we need physical activity in our lives? Physical Activity and Diabetes (Epidemiology) Conclusion Bibliography Introduction For our seminar topic "physical activity and disease" we chose diabetes as the focus of our research. Since diabetes is such a complex disease with many different forms, we decided to focus on diabetes type I. This is known as insulin-dependent diabetes mellitus (IDDM). This type of diabetes includes people who are dependant on injections of insulin on a daily basis in order to satisfy the bodies insulin needs, they cannot survive without these injections. OVERVIEW OF DIABETES TYPE I What is diabetes type I? In order to understand the disease we firstly need to know about insulin. Insulin is a hormone. The role of insulin is to convert the food we eat into various useful substances, discarding everything that is wasteful. It is the job of insulin to see that the useful substances are put to best use for our well-being. The useful substances are used for building cells, are made ready for immediate expenditure as energy and also stored for later energy expenditure. The cause of diabetes is an absolute or lack of the hormone insulin. As a result of this lack of insulin the processes that involve converting the foods we eat into various useful substances does not occur. Insulin comes from the beta cells which are located in the pancreas. In the case of diabetes type I almost all of the beta cells have been destroyed. Therefore daily injections of insulin become essential to life. Health implications of diabetes type I One of the products that is of vital importance in our bodies is glucose, a simple carbohydrate sugar which is needed by virtually every part of our body as fuel to function. Insulin controls the amount of glucose distributed to vital organs and also the muscles. In diabetics due to the lack of insulin and therefore the control of glucose given to different body parts they face death if they don't inject themselves with insulin daily. Since strict monitoring of diabetes is needed for the control of the disease, little room is left for carelessness. As a result diabetic patients are susceptible to many other diseases and serious conditions if a proper course of treatment is not followed. Other diseases a diabetic is open to: Cardiovascular disease, stroke, Peripheral artery disease, gangrene, kidney disease, blindness, hypertension, nerve damage, impotence etc. Basically there is an increased incident of infection in diabetic sufferers. Therefore special care needs to be taken to decrease the chances of getting these other serious diseases. PHYSICAL ACTIVITY What is physical activity? (Bouchard 1988) States that physical activity is any bodily movement produced by skeletal muscles resulting in energy expenditure. Therefore this includes sports and leisure activities of all forms. Why do we need physical activity in our lives? Physical activity and exercise helps tune the "human machine", our bodies. Imagine a car constantly driven only to stop for fuel. It would be a client for all sorts of damage, rusting, oil leaking, dehydration and the chances are most likely it would die in the middle of the road not long after. This is what the body would be like if we didn't exercise at all. We would be and as a result of todays lifestyle many of us are, the perfect target to all kinds of diseases and infections. For those of us who are carrier of some disease or illness we are still encouraged to exercise by our physicians if we have the strength to. This is to help make our organs, muscles, bones and arteries more efficient and better equipped to fight against the disease or illness. This is our way of counter attacking. And if we are still healthy then we reduce the chances of getting an illness or a disease. PHYSICAL ACTIVITY AND DIABETES (EPIDEMIOLOGY) Recently insulin injections have become available to dependant patients. However in the pre-insulin era physical exercise was one of the few therapies available to physicians in combating diabetes. For an IDDM carrier to

Tacitus essays

Tacitus essays During the 1st century A.D., Rome was experiencing extreme political instability. Neither of the dynasties during the century, the Julio-Claudian and the Flavian, provided long-term stability because of the ineptitude of the emperors. Most of the emperors of the period were fearful of other family members overthrowing their reign. The emperors fear of being overthrown lead to mass executions of the royal family, which caused further political instability. Tacitus came to prominence in the political arena during this highly unstable period. Born to an upper class family, he was a senator during the reign of the last Flavian emperor, Domitian. He was fearful of the abuse of power and intimidation brought upon by Domitian. He states, The worst of our torments under Domitian was to see him with his eyes fixed upon us. Every sigh was registered against us and when we all turned pale, he did not scruple to make us marked men by a glance of his savage countenance. (98). In Tactitus writings, The Agricola In The Agricola, Tacitus reflects on the life of his father-in-law Agrippa, a Roman military commander. The story discusses Agrippas occupation of Britain, his subsequent reign, and finally his return to Rome, during the latter part of the 1st century A.D. Tacitus focuses on the struggles the Britons faced during Agricolas rule of Britain, and Agricolas struggle upon his return to Rome. In the first part of the story, the Britons attempted to fight the Roman onslaught, only to be conquered by Agricola. While numerous groups of barbarians attempted to stem the Roman charge, the opposition was brutally vanquished, and Agricola consolidated his reign. The Britons that did not attempt to halt the Roman advances were spared. ...

Telecommunications Essay Example | Topics and Well Written Essays - 6500 words

Telecommunications - Essay Example Nevertheless information is also important to economic activities, ranging from agriculture to manufacturing and services. If information is significant to advancement, then telecommunications, as a way of sharing information is not only a relationship between people, although a connection in the sequence of the advancement processes itself. The role of telecommunications in broadcasting information can be predominantly important in rural regions where other methods of acquiring and transmission information for instance personal contact, transport, and postal services are expected to be less available. Distance signifies time, in an all the time more time-conscious world. In economies that rely forcefully upon agriculture or the mining of resources, remoteness from urban markets has usually been improved only with the setting up of enhanced transportation facilities, usually roads. Nevertheless transportation links leave industries without the availability of information which is becoming ever more important for production and marketing of their products. Yet another difficulty experienced by many developing countries is economic field. As they endeavor to expand their economies, judicious availability of information becomes especially significant. In the demand of physical goods and amenities, rural areas could only vie across obstacles of distance and geography if they had a natural resource advantage. Telecommunications is also critical to the rising information fields in developing areas. In the areas of information goods and services, dependable telecommunications infrastructure can make geography and distance immaterial. For instance, the National Research Council reveals that for Africa, where populations and economic activities continue mostly rural-based, sharing information is crucial if Africans are to contribute to finding solutions to their own development problems: "Economic development in Africa will depend heavily on the development of the information sector. Countries will need the ability to communicate efficiently with local and overseas markets to determine where they many have comparative advantages for supplying their products to consumers or to purchase essential imports, based on current prices and services. Many of the economic development problems facing African countries have scientific and technological components that will require solutions to be developed in Africa by African scientists.... Lack of information is a critical constraint" (National Research Council, 1990). In the past several years, the role of telecommunications in the development process has acquired extensive focus. The ITU performed a series of analyses starting with a literature research, followed by a series of case studies on different developmental applications of telecommunications, which were summed up in Telecommunications for Development (1983). Other case studies were compiled in Information, Telecommunications, and Development (1986). The ITU's Maitland Commission pointed at the significance of telecommunica
