... environmental and life-style factors (where you live, salt and other chemicals, weight, stress, alcohol, lack of exercise). The difference between primary and secondary hypertension is that we know the causes of secondary hypertension. Usually, the causes of secondary hypertension include renal artery stenosis (or other cause of increased plasma renin), renal parenchymal disease (glomerulonephritis, diabetic nephropathy, polycystic disease, obstructive uropathy), drugs (oral contraceptives, steroids), and increased levels of catecholamines (pheochromocytoma), glucocorticoids (Cushing's disease), or mineralcorticoids. Symptoms Hypertension is referred to as "t ...

... and the file would be found in a few seconds. On a computer you could automatically put the files in alphabetical order by whatever- name, GP, date of birth e.t.c. However, in an office cabinet it really would not be easy at all to put and keep the files in some sort of alphabetical sequence. Currently the database is pen-and-paper based, which may be cost effective but is very time-consuming when compared to a computer-based database. Say you have a paper-based database. If one of your clients move house or get married, you would have to create a whole new record because of the altered information. And say it was a family who moved residence, and then after you ma ...

... one is extremely rough and old while the other is young and relatively smooth. The southern hemisphere is strewn with ancient craters of all sizes and is also elevated by a several kilometers creating a visible boundary. On the opposite end the northern hemisphere consists of a wider variety of geological features, but is obviously smoother and much younger. There are large volcanoes, a great rift valley, and a variety of channels. Volcanism is a geological process that occurs on Earth today, and has on many planetary bodies throughout the history of the solar system. No volcanism is occurring on the surface of Mars today. In the past, however, volcanism was ...

... fuel which contains energy©giving substances that our bodies can store until we need this energy to use our muscles. When we do use our muscles within us, we may not always be sure that heat is given off. Our bodies do not burst into flames but the perspiration on our skin is a clue to what is happening. The movement of the windsurfer has a different explanation. The windsurfer is propelled along by a sail which collects mechanical energy from the winds that sweep along the water. This energy has been produced by the sun which warms the earth's surface and sets the air above in motion. The sun's heat comes to the earth as a form of radiant energy. When th ...

... concept of sea level rise as a codeword for “retreat,” giving up protective measures for the barrier island communities.There has been polarization in the past between some mayors and public officials who favor public expenditures to hold back the sea and other public officials and some scientists who are skeptical about erosion-fighting programs. There were those who believed people should not be allowed to rebuild in hazardous areas and those who would not forbid them to build as long as they did not ask for recompense when they got into trouble. One group has felt property owners should not be compensated if they are forbidden to rebuild, and others say ...

... these groups can be used to identify molecules that are in that class. This lab is broken down into four different sections, the Benedict's test for reducing sugars, the iodine test for the presence of starch, the Sudan III test for fatty acids, and the Biuret test for amino groups present in proteins. The last part of this lab takes an unknown substance and by the four tests, determine what the substance is. BENEDICT'S TEST Introduction: Monosaccharides and disaccharides can be detected because of their free aldehyde groups, thus, testing positive for the Benedict's test. Such sugars act as a reducing agent, and is called a reducing sugar. By mixing the ...

... 1). Many soldiers in the Vietnam War encountered repeatedly. Their lives revolved around the 55-gallon drums, which once were filled with an extremely harmful herbicide. Unaware of the possible consequences, many soldiers built showers and hibachis out of these discarded drums (Doyle, 139). They also used the barren drums to store potatoes and watermelons (Doyle, 139). One man described to his wife how they would bathe and swim in water contaminated with because their superior said it was safe (Brooks, 2). “After the LZ was sprayed, we walked around the perimeter, strung barbed wire all around it, and this stuff [] was blowing all over the place.

... If that embryo could be cloned and turned into three or four, thechances of a successful pregnancy would increase significantly"(Elmer- Dewitt 38). The experiment the scientists performed is the equivalent of a mother producing twins. The process has been practiced and almost perfected in livestock for the past ten years, and some scientists believe that it seems only logical that it would be the next step in in-vitro fertilization. The procedure was remarkably simple. Hall and Stillman "selected embryos that were abnormal because they came from eggs that had been fertilized by more than one sperm" (Elmer-Dewitt 38), because the embryos were defective, i ...

... is commonly connected with a "wasting syndrome," which results in substantial weight loss, a general decline in health, and, in some cases, death. The virus also infects the nervous system. There, HIV may cause dementia, which is a condition characterized by sensory, thinking, and/or memory disorders. HIV infection of the brain may cause movement or coordination problems. HIV’s disruption of the immune system makes infected people susceptible to illnesses that are not normally serious. These diseases are called opportunistic illnesses because they take advantage of the damaged immune system. With the onset of several of these illnesses, an infected person ...
