.... bathing. The solar panels generate "low grade" heat, that is, they generate low temperatures for the amount of heat needed in a day. In order to generate "high grade" heat, intense enough to convert water into high-pressure steam which can then be used to turn electric generators there must be another method. The concentrated beams of sunlight are collected in a device called a solar furnace, which acts on the same principles as a large magnifying glass. The solar furnace takes the sunlight from a large area and by the use of lenses and mirrors can focus the light into a very small area. Very elaborate solar furnaces have machines that angle the mirrors and lenses to the ....

.... obtained by clinical observations, interrogation to obtain a detailed case of history, and palpation of the pulses. There are three main methods of diagnosis that are employed in the clinic: looking, asking and palpating, all of which contribute to a full and accurate diagnosis of the patient’s condition. By looking at the patient’s face, body and movements, the practitioner is already beginning to create a diagnosis. Another major diagnostic tool is the tongue. It is said that the state of the internal organs is reflected in the tongue, and the practitioner will note the color and shape of the tongue as well as its coating. All patients can expect their pulse to be taken ....

.... the genetic defect. In about 5% of cases, hemophilia-A results from partial deletion of the factor VIII gene, and is severe. Other cases result from a single base mutation in the gene. This can result in nonsense mutations which result in premature stop codons, and a severe expression of the disorder, or missense mutations which cause milder forms of the disorder. In some cases the disorder can also result from spontaneous mutations, but this is less common. The gene for hemophilia-A is located at Xq28 while the gene for hemophilia-B is located at Xq27.1-q27.2. There are about thirty other disorders associated with the Xq28 area including manic depression and favism. This m ....

.... life cycle of a monarch revolves around the Butterfly weed plant. First the monarch lays its egg on the leaf of the plant. Once the Caterpillar is born it eats the leaf for nutrition. The Monarch caterpillar is striped black and yellow. As it grows and becomes ready to become a chrysalis by forming a cocoon it uses the plant again. The caterpillar forms its cocoon on the Butterfly Weed. By the time the caterpillar is ready to become a chrysalis it has grown to be about 45 millimeters in length. The chrysalis is pale green and spotted with gold. It becomes more transparent as the butterfly gets ready to break free. The adult Monarch has a wingspan of about 4 inches. Th ....

.... discovered until around 1750, when the Spaniards discovered it in Peru. They named the metal platinum, deriving from their word plata, meaning silver. The ore, called native platinum, usually occurs in beds of gold-bearing sand. Miners call it white gold. Native platinum contains from 60 to 85 percent pure platinum. The small, irregular grains that contain the ore also contain other rare metals, such as iridium, osmium, palladium, rhodium, and ruthenium. The grains also contain small amounts of iron, copper, chromium, and titanium. A large nugget of platinum will be found only on occasion, like in 1843, a lump weighing over 21 pounds was found in Russia. Russia produc ....

.... of life on Mars." ( Sagan and Shklovskii 273) Some scientist believe man should look up in the sky searching for new habitats for future generations, since human kind today seems to be going backwards in many aspects of the earth's ecology. The first attempt would be to study the moon; the second, our neighbor planet. Unfortunately, our actual technology slightly provides strong, useful information about the red planet because of the vast distance between us. While people such as Steven Spielberg and George Lucas try to convince us with hundred million dollar movies that we are not alone, engineers and geologists like from the NASA-Stanford University team pursue, ....

.... known to medicine: the ectopic pregnancy. Ectopic pregnancies are the number one cause of death of women in the first trimester of pregnancy. There are many aspects that have to taken care of when an ectopic pregnancy is identified. Not only are there the symptoms, the diagnosis, the treatments, and the results to deal with, but also moral ethics come into play. The term “ectopic” literally means “out of place”. Other things in the human body can also be considered ectopic if it sits in an abnormal position in the body. A heart beat that originates from and unusual part of the heart is an “ectopic” heart beat, and a baby that is not properly nestled in the ut ....

.... there is a considerable source of heat. This is necessary to maintain a consistent supply of rising air in the form of currents. There needs to be a large supply of moisture, as it is necessary for condensation to take place in order to release latent heat and it is the latent heat that initiates the development of the storm and consequently produces heavy rainfall. When the hurricane reaches its maturity an eye develops in the centre, in the eye there is a relative area of subsiding pressure. Which is what causes clear skies, anomalous high temperatures and light winds. Eventually the eye disappears as a result of the descending air increasing instability, which in turn warm ....
