.... in soil can be grown in a hydroponic system! Flowers, herbs, vegetables, fruit trees, vines, and ornamental shrubs. Everything from Aloe Vera to Zucchinis can be grown in this unique system. There are many advantages to using a hydroponic system for growing plants. The most obvious being that it is easier to control the plant growing environment. Some others are restricted supply of suitable water, lack of suitable soil, high labor cost of traditional cultivation, high cost of sterilizing soil, and there is a greater reliability and predictability of plant production. In addition, It's easy! Depending on what is being grown, most of the time hydroponic plants require l ....

.... less than one million years. It has even been speculated that some of the younger stars within the cluster are only 300,000 years old. The is an emission nebula because of the O-type and B-type stars contained within it. These high-temperature stars emit ultraviolet (UV) light that ionizes the surrounding hydrogen atoms into protons (H+) and electrons (e-). When the protons and electrons recombine, the electrons enter a higher energy level (n=3). Then, when the electron drops from the n=3 level to the n=2 level, an Hphoton is emitted. 2 This photon has a wavelength of 6563 Å, and therefore corresponds to the red portion of the visible spectrum. It is t ....

.... surgery was an athletic badge of honor to be displayed on one's knees with corrugated streaks of purplish flesh. Little did I realize what it takes to recover. My father had orthoscopic surgery twice, and both times he was walking within a day and cycling within a week. I assumed my recovery time would be similar to his. Never in my life have I been so wrong. Due to the nature of the injury, the doctor elected to stitch my cartilage back together. Because of the intricacy of the operation, I was restricted to non-weight bearing activities for three weeks. If I wished to return to wrestling, the doctor stated that I would have to demonstrate a muscle strength in my ....

.... made up of carbon, nitrogen, oxygen, and hydrogen. When combined with more conventional compost ingredients such as manures, sawdust, straw, and fruit and vegetable processing wastes, the explosives become broken down into harmless chemical forms. The Army is using composting to clean up munitions processing wastes at several of its ammunition plants, including ones in Louisiana, Wisconsin, and Oregon. At the Oregon site, composting is projected to save 2.6 million dollars compared with incinerating the contaminated soils. In addition to saving money, composting will also avoid the need for burning fossil fuels and will produce an end product usable for backfilling, landscap ....

.... on the horizon now, is the possibility of designing your child to be “perfect”. Over the years, there has been heated, ethical controversy on each of these issues, especially designer babies. How far will we let biotechnological discovery take us? What will come of the world if designer babies become standard procedure? The earliest and maybe simplest use of genetic manipulation was in the selection of the sex of an unborn child. In Vitro Fertilization(IVF - A procedure in which a woman’s eggs are removed from her body, fertilized outside using sperm from her husband or another donor, and then transferred back to her body.) was originally lim ....

.... this mysterious planet will expand. The atmosphere of Mars is quite different from that of Earth. It is composed primarily of carbon dioxide with small amounts of other gases. The six most common components of the atmosphere are Carbon Dioxide at 95.32%; Nitrogen at 2.7%; Argon at 1.6%; Oxygen at 0.13%; Water at 0.03%; and Neon at 0.00025 %. Martian air contains only about 1/1,000 as much water as our air, but even this small amount can condense out, forming clouds that rise high in the atmosphere or swirl around the slopes of towering volcanoes. Local patches of early morning fog can form in valleys. At the Viking Lander 2 site, a thin layer of water frost covered the gro ....

.... United States alone. It is difficult to obtain accurate statistics on lightning injuries and fatalities since a systematic compilation of information on lightning casualties does not exist. Many case histories show heart damage. Inflated lungs and brain damage have also been observed from lightning fatalities. Loss of consciousness, amnesia, paralysis and burns are reported by many who have survived. Deaths and injuries to livestock and other animals, thousands of forest and brush fires, as well as millions of dollars in damage to buildings, communications systems, power lines, and electrical systems are also the result of lightning. Finally, the threat of lightning causes ....

.... Physical Effects of Alcohol The effects of alcohol on the human body depend on the amount of alcohol in the blood (blood-alcohol concentration). This varies with the rate of consumption and with the rate at which the drinker's physical system absorbs and metabolizes alcohol. The higher the alcohol content of the beverage consumed, the more alcohol will enter the bloodstream. The amount and type of food in the stomach also affect the absorption rate. Drinking when the stomach is filled is less intoxicating than when it is empty; the foods in the stomach, which contain fat and protein, delay alcohol absorption. Body weight is also a factor; the heavier the person, the ....
