- 221: Nuclear Power
- ... pellets coated with ferrous oxide and maintained at a temperature of 500 C. In the treatment of liquid wastes, the condensates collected contain about 15% ruthenium. This is then concentrated in an evaporator where nitric acid is destroyed by formaldehyde so as to maintain low acidity. The concentration is then neutralized and enters the vitrification pot. Once the vitrification process is finished, the containers are stored in a storage pit. This ... the best for all receiving formations. With such a pH range, breakdown of the formation rock and dissociation of the formation water are avoided. The stability of waste containing metal cations which become hydrolysed in acid can be guaranteed only by complexing agents which form 'water-soluble complexes' with cations in the relevant pH range. The importance of complexing in the preparation of wastes increases because raising of the waste solution ... the bonds between isotopes and formation rock. Now preparation of the formation is as equally important. To reduce the possibility of chemical interaction between the waste and the formation, the waste is first flushed with acid solutions. This operation removes the principal minerals likely to become involved in exchange reactions and the soluble rock particles, thereby creating a porous zone capable of accommodating the waste. In this case the required ...
- 222: Protein Synthesis
- ... without risking the DNA in the cytoplasm. The mRNA travels through the cell to a ribosome. Here tRNA which contain the appropriate anti-codon collect the amino acids coded for in the mRNA. Each amino acid is connected to the next amino acid. The mRNA thus transverses the ribosome with each three nitrogen base condon selecting an amino acid. This continues until the ribosome encounters a stop condon. When this happens the amino acid chain is released from the tRNA and is a protein. This process allows for the genetic information stored in ...
- 223: Prions
- ... as a sign of respect their brains where eaten and the chain went on and on. The thing that makes prions so special is the fact that they lack the basic elements for reproduction, deoxyribonucleic acid and ribonucleic acid DNA and RNA respectively. This is what has given science a great deal of doubt as this would give the dogma of the beginning of live a radical turn. Prions have been in research for ... of the scrapie agent depends on a protein (PrP, called later when discovered it was a single molecular specie protein). This protein was found to be a glycoprotein (PrP): sugars are bounded to the amino acid, and it is half the size of hemoglobin. PrP is the protein, but we can also find today PrPc (for cellular) and PrPsc (for scrapie). Prp can be found in steak ( skeletal muscle) and ...
- 224: Lsd 2
- ... wrong belief by users that it is a safer drug than marijuana because it isn't physically addicting. However, LSD is a hallucinogenic drug that is very dangerous, despite popular belief. LSD stands for Lysergic Acid Diethylamide. Lysergic acid is extracted from the fungus Ergot, and then left to crystallize until it is pure. It was first accidentally discovered by Albert Hoffman in 1938 in Switzerland, who was searching for possible therapeutic uses of ... his experiments, but never came in contact with the crystals until1943. (LSD can be absorbed through the skin.) Hoffman then sent LSD around the world to be tested and investigated to find medical uses. Lysergic acid deviates were found to relieve migraines and control postpartum hemorrhage because it causes veins to contract, but also caused gangrene of the limbs, and so further experimentation with the drug was abandoned. In the ...
- 225: Noah's Ark and The Great Flood
- ... height of Everest is 1,087,190,293,000 km³. Subtracting the first volume from the second gives approx. 4,493,361,000, or four thousand, five hundred million cubic kilometers of water! Also, the rain is supposed to have fallen in about 40 days. That means that there would have been about 220 m of rainfall every day over the entire planet (8800/40 = 220)! (Note: volume of sphere = 4/3 pi r³, and I use the American billion of 1,000,000,000 here). Since rain is fresh water, this would have severely diluted the oceans, causing devastation among the marine creatures. Ask anyone with a marine fish-tank just how sensitive reef-fish and corals are to changes in water ... south poles? How did the giant tortoises get back to the Galapagos Islands? How did the dodos get back to Mauritius (or was it Madagascar)? How did the army ants get back to the Amazon rain-forests? And as you will see under the next topic, what of the dinosaurs? As there were only two (or seven, depending) of each species, how did they manage to travel thousands of miles ...
- 226: Skeptical Views On Noahs Ark
- ... flood was coming and built the barge solely as a lifeboat. Alternatively, if he built the barge to transport cattle and grain to market and had no inkling that a flood was coming until the rain began to fall, then using the barge to escape a local flood makes sense. When the river overflowed the levees, it was too late to evacuate to the foothills of the Zagros mountains which were ... built as a lifeboat. It was built long before the flood as a commercial river barge for transporting cattle, grain, and other cargo. Noah learned that the flood was coming only when he saw heavy rain falling. This was a few hours before the river overflowed the levees. Noah did not know the flood was coming when he commissioned building the river barge. How do you explain the conflict between the ... and family overland to the foothills of the Zagros mountains? Your hidden assumption is that Noah knew long in advance that the flood was coming. Actually he knew the flood was coming only when heavy rain began to fall. By then it was too late to travel to the mountains that were more than a hundred miles away. How did Noah know the flood was coming? During the annual inundation, ...
- 227: Marketing A New Product
- ... a market, or at least, there is no similar existing product. It is a conventional swivel clothesline, but with an additional feature. It will have the ability to keep clothes dry when it starts to rain. This is achieved by the water sensors, which are integrated into the design. They then activate an umbrella like cover that shields the clothes from the rain. Marketing Environmental Analysis The marketing environment consists of a Microenvironment and a Macroenvironment. The microenvironment deals with internal factors, which could affect the company's ability to service its market, such as competitors, suppliers, distributors ... society is changing to become more rushed and people have less time for household chores. 'No Worries' clothesline will mean that people can go out without worrying about whether or not it is going to rain and their fresh laundry will get wet again. My company could affect the region, in that more people from that area are being employed. Legal Forces My company would have to work within the ...
- 228: Jaguars
- ... to the tip of South America, now centres on the north and central parts of the South American continent. The jaguar is predominantly a forest dweller with the highest population densities centring on the lowland rain forests of the Amazon Basin - dry woodland and grassland also serve as suitable terrain, although the cat is rarely found in areas above 8000 feet. The overall body size and coloration of the cat often ... he water to hide the carcass in the dense undergrowth. Equally at home as a climber, although not as adept as the leopard, the jaguar will hunt monkeys in the lower branches of the large rain forest trees. In much of its range where man lives close by, the jaguar now has to compete with the human hunter and poacher who takes many of the same species as the big cat ... on the establishment of protected National Park areas which may serve to reduce the decline of the jaguars natural habitat. In Belize, the government, aided by the WWF, have set aside 150 square miles of rain forest in the Cockscomb Basin Wildlife Preserve, which currently provides a protected environment for around 200 jaguars, the largest concentration of the wild cats species in the world. The WWF are also providing aid ...
- 229: Ghosts 2
- ... Ghosts , Ibsen forces the reader to think about his own ideas and believes, as well as those of society and past ages. Symbolism is one technique repeatedly used to portray the author s ideas through rain, light, fire, the orphanage, Oswald, and through Engstrand himself. The use of religion is also interesting in the way the town people and Pastor Mander uses it. There are many symbols present throughout Ibsen s work. Rain is used as a symbol of the cleansing of evil and impurities. Outside of Mrs. Alving s home it remains rainy and stormy until she faces the truth about her husband. The rain washes away the disguises so that the truth may be seen. Generally when this takes place the sun, another symbol, rises, revealing the reality of the situation. Mrs. Alving said, And there we are, ...

- ... a strong cough surpe and it made him drunk. After they got him settled down they were off to California. Chapter 11 Now the houses were left vacant and completely abandoned. When a small little rain fell grass grew up where there was never any before. The grass grew in between the boards in the porch and the doors swung open. The families were gone from the land they once loved ... a good meal every day. Chapter 29 The chapter talks about the on coming rains. The rains will last a couple of months. The rains are much like the peoples spirits, dark and gloomy. The rain will stop all work for months and the people will starve. No work means no food. The rain leaks in the cars and the cars wont start. The people are stuck where they are. Chapter 30 The rain has started. They hoped it would last for only a couple of days ...
