... and deadly gas given off when any fuel is incompletely burned by, for example, a furnace or water heater (Marable 97). Unlike a fire where you can immediately see smoke and flames, carbon monoxide poisoning gives no physical evidence of its presence. But, when taught to see and look for the warning signs of carbon monoxide, deaths in the home due to carbon monoxide poisoning can be prevented. Sometimes, in a home the hot water supply is low, or the furnace fails to keep the house warm. A natural reaction in any of these situations would be to turn up the tempeture on both appliances. But, did you know that a low supply of hot water, and a furnace that doe ...
... became quite an expert. “Do your best” was the general idea, and most surgeons did, or at least tried. Nearly all the older doctors had received their education on an apprenticeship basis but the younger men, those who made up the bulk of the army surgeons, usually held a medical school diploma along with an office internship. Little attention was paid to clinical instruction, and in most cases the laboratory was all but forgotten. Further, stethoscopes, thermometers, syringes, and the like were widely used in Europe while many doctors here at home had never seen them let alone used them. In regard to ability and competence, there is no reason to bel ...
... that microwaves, with their short wavelength, could be focussed ina narrow beam with an antenna many times smaller. This enabled them to make more effective use of radar since an antenna could be carried on aircraft, ships and mobile ground stations. This characteristic of microwaves, the efficiency with which they are concentrated in a narrow beam, is one reason why they can be used in cooking. You can produce a high-powered microwave beam in a small oven, but you can't do the same with radio waves, which are simply too long. Microwaves and their Use The idea of cooking with radiation may seem like a fairly new one, but in fact it reaches back thousands o ...
... the air is due to the subtropical highs. These highs like the ITCZ migrate during the different seasons. The idealized belt model is a great representation of the general circulation of the atmosphere. The equatorial belt of variable winds and calms ranges from 5 degrees north to 5 degrees south. This wind belt is characterized by weak winds and low pressure from the inter tropical convergence zone. As you go further north or south you encounter the Hadley Cells. Hadley cell circulation is caused by the movement of high pressure from the latitudes at 5 to 30 degrees north and 5 to 30 degrees south to low pressure areas around ...
... the treatment methods. In about 1743 gentle stretching was recommended. During that same century, a mechanical device resembling a turnbuckle was used to help stretch the tendons. By this time was pretty well known around the world, using the typical stretching and splinting methods. In the 1800’s plaster of paris was first introduced, and later that same century, the introduction of aseptic technique and anasthesia diminished, but not eliminated infection. As the 70’s and 80’s rolled around, other more reliable methods were depended upon. These new methods were less dependent on wrapping and taping. The majority of clubfeet results from abnormal devel ...

... have been "cloned". So far, scientists have used genetic engineering to produce, for example: - improve vaccines against animal diseases such as footrot and pig scours; - pure human products such as insulin, and human growth hormone in commercial quantities; - existing antibiotics by more economical methods; - new kinds of antibiotics not otherwise available; - plants with resistance to some pesticides, insects and diseases; - plants with improved nutritional qualities to enhance livestock productivity. Methods: - Manipulation of the Gene pool, which is related to Hybridization which is the breeding of species but the species are not the same but they are relate ...
... is linked to an inner, light-sensitive circadian rhythm. In the temperate zones, day lengths during the natural 24-hour cycle vary with the seasons. In winter and spring, the period of light lengthens; in summer and autumn, it shortens. Plants in these zones undergo alternate 12-hour phases of light sensitivity. During one 12-hour phase, decreasing exposure to light induces a short-day reaction. For example, deciduous trees under the influence of the shorter days of fall drop their leaves. During the other 12-hour phase, more exposure to light creates a long-day reaction. Deciduous trees grow leaves again during the lengthening days of spring. This indicates tha ...
... From outside the storm area, air moves in over the sea surface to replace the air soaring upwards in the thunderheads. The air begins swirling around the storm center, for the same reason that the air swirls around a tornado center. As this air swirls in over the sea surface, it soaks up more and more water vapour. At the storm center, this new supply of water vapor gets pulled into the thunderhead updrafts, releasing still more energy as the water vapor condenses. This makes the updrafts rise faster, pulling in even larger amounts of air and water vapor from the storm's edges. And as the updrafts speed up, air swirls faster and faster around the storm cen ...
... became an "organic soup". Eventually, the proteins in this "organic soup" joined, a membrane grew around the proteins, and the first complete cell was formed (Dawkins 16). According to evolution, this process was the beginning of life. But, there are minimal chances that this organic soup would form. Consider the experiment of Stanley Miller. In 1953, Stanley Miller passed an electric spark through an atmosphere of hydrogen, methane, ammonia, and water vapor; an atmosphere similar to the so-called "primitive atmosphere." But, this produced only 4 out of the 20 amino acids essential to form life. Interestingly, though, Miller saved the four amino acids only by remo ...
