... that my Dad did not know, which was very rare. Though that was great, it was not the best part of my adventure. The best part of my experience was in the water. We set out to sea around 5:00pm and returned at around 9:00pm. Those four hours were probably the best four hours of my adolescent life. When I was out on the kayak I saw so many killer whales it was unbelievable. We were in the midst of two whale pods numbering about 90 whales. I had heard that killer whales can attack people. Surprisingly, I was not afraid except for the fact of how cold the water was. It was so cold that if our kayak capsized both my father and I would have died in about 10 ...
... are not suited to the careful control and flexible manipulation required for a successful ‘strike’, or actual crystallization, of solid sugar . For this purpose, the concentrated liquor is transferred from the evaporators to the ‘pan.’ The pan is essentially a simple vacuum evaporator in which the removal of water continues until the concentration is appropriate for crystallization. As this proceeds, juice continues to be drawn into the pan in order to maintain a supply of crystallizable sugar. The concentration of impurities increases in the syrup as sugar is withdrawn by crystallization, and the entire boiling mass stiffens as the viscosity inc ...
... the lamina of the leaf is within less than 15° from the normal to the sun. Many plants that exhibit diaheliotropic movements also show paraheliotropic response as well. Paraheliotropism minimizes water loss by reducing the amount of light absorbed by the leaves; the leaves orient themselves parallel to the sun’s rays. Plants that exhibit paraheliotropic behavior usually do so at midday, when the sun’s rays are perpendicular to the ground. This reorientation takes place only in leaves of plants that are capable of nastic light-driven movements, such as the trifoliate leaf of Erythrina spp. (Herbert 1984). However, this phenomenon has been observed ...
... 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 injured knee equal to ninety percent of my good one. When informed of this requirement, I could barely bend my leg twenty degrees nor use it to lift a ten-pound weight. One week after surge ...
... to our presence" (Kralijic, 1992). Ways must be found to lessen the threat of this growing crisis. If this effect were to continue and grow, the earth’s population would be exposed to serious threats. Carbon dioxide is essential for plants who use it for photosynthesis, yet too much can lead to serious threats. The problem lies in the disruption of the balance between how much carbon dioxide plants intake, and what our population produces. If this natural filtering process is unbalanced, the atmosphere will receive too much carbon dioxide and other greenhouse gases. Once these gases form in the atmosphere, they act as barriers trapping in heat and warming the ea ...
... collapse of a star, usually having a great, massive, core. A star is created when huge, gigantic, gas clouds bind together due to attractive forces and form a hot core, combined from all the energy of the two gas clouds. This energy produced is so great when it first collides, that a nuclear reaction occurs and the gases within the star start to burn continuously. The Hydrogen gas is usually the first type of gas consumed in a star and then other gas elements such as Carbon, Oxygen, and Helium are consumed. This chain reaction fuels the star for millions or billions of years depending upon the amount of gases there are. The star manages to avo ...
... within the Earths atmosphere, which is slowly increasing the average heat levels. Scientists predict that the average temperature will rise 1.6 – 6.3°F by the year 2100, which could wreak havoc with climates around the world. Why are greenhouse gas concentrations increasing? Scientists generally believe that the combustion of fossil fuels and other human activities are the primary reason for the increased concentration of carbon dioxide. Energy burned to run cars and trucks, heat homes and businesses, and power factories is responsible for about 80% of society's carbon dioxide emissions, about 25% of U.S. methane emissions, and about 20% of global nitr ...
... it is electrically neutral. The electrons have discrete kinetic energy levels, which increase with the orbital radius. When atoms bond together to form a solid, the electron energy levels merge into bands. In electrical conductors, these bands are continuous but in insulators and semiconductors there is an "energy gap", in which no electron orbits can exist, between the inner valence band and outer conduction band [Book 1]. Valence electrons help to bind together the atoms in a solid by orbiting 2 adjacent nucleii, while conduction electrons, being less closely bound to the nucleii, are free to move in response to an applied voltage or electric field. The fewer cond ...
... many people began to question the possibility of not only creating genetically identical sheep, but humans as well. There has been much controversy on whether or not the cloning of humans as well as animals is ethical or even moral. Also there has been much discussion as to whether or not the benefits of cloning outweigh the dangers. WHAT ARE THE BENEFITS IN CLONING RESEARCH? There is no doubt that Dr. Wilmut's new discoveries have brought an uproar of excitement between not only the scientific community, but the general public as well. Groups such as farmers, surgeons and even environmentalists have shown various interests in cloning research. The farmi ...
... lakes had been destroyed by acid rain. The problem has been most severe in Norway, Sweden, and Canada. The threat posed by acid rain is not limited by geographic boundaries, for prevailing winds carry the pollutants around the globe. For example, much research supports the conclusion that pollution from coal-powered electric generating stations in the midwestern United States is the ultimate cause of the severe acid-rain problem in eastern Canada and the northeastern United States. Nor are the destructive effects of acid rain limited to the natural environment. Structures made of stone, metal, and cement have also been damaged or destroyed. Some of the world's g ...
