- 101: Over Population
- ... the earth7. As the population increases, atmospheric concentrations of greenhouse gases rise rapidly which affect the ability of the outgoing energy to pass through the atmosphere, [which] effectively heats the Earth8. Another predicament is the acid rain created by air pollution, which in turn, is created by the increasing population. Acid rain’s spread and damage involves weather, soil, and the life cycles of plants and animals on the land9. Air pollution is created from the burning of fossil fuels in cars, trucks, planes, and ...
- 102: The Cat In The Rain: Self Control and Communication
- The Cat In The Rain: Self Control and Communication It was a windy spring day in Chicago. I stood on the bridge of Michigan Avenue looking down the Chicago river. The river was choppy and crashed against the concrete walls ... myself why was the father going so fast in that boat if his daughter was so blatantly miserable. Ernest Hemingway also deals with self control and communication in his short story ‘The Cat In The Rain’. Hemingway opens up the story during a dismal rainy day. It is a common fact that people tend to become more grouchy during rainy days. The wife Hemingway introduces seems to be extremely bored. She ...
- 103: Creative Writing: Under The Spell - A travel tale by Danny O'brien
- ... truth, mind you, certainly not for our mutual amusement, to describe another Irish road story, much to the dismay of the Irish Tourist Board and Ministry of Roads. It was another typical Irish day, soft rain falling. While driving on a rather nice road I saw what appeared to be nothing more than a large shallow puddle on the road, the kind that are great fun to run through to hear ... into our wee for hire red Ford Fiesta and headed off for Killarney. A rare sunny day in Ireland is a day when the sun is out over a few hours and it doesn't rain too much. By the time we reached Ballydehob on the Mizen peninsula our thoughts were back to finding the appropriate weather gear for Ireland. The prevailing direction of Ireland's rain is horizontal, our umbrellas were useless. On the main street of the village of Ballydehob we spotted a very small bright red store with rainwear, boots, and about everything else hanging outside the door. ...
- 104: Deforestation in the Brazilian Amazon
- ... part is called Amazonia, after the Amazon river, which runs through it. This region covers 40% of Brazil's surface and extends into many of the surrounding countries. It is mostly covered with dense tropical rain forests and contains an enormous variety of plants and animals. Although rain forests constitute only 7% of the earth's land surface, they contain 50% of its living species! (Revkin, 34) Unfortunately, these forests are now being cut down for profit. Some say this is not a ... few advantages all of which are in the short term, it has terrible consequences and its long term effects are devastating, this is why it should be stopped. Since its discovery, 30% of Brazil's rain forests have disappeared, and the country is still losing more rain forest each year than any other on the planet. Brazilian forests are burned or felled at the rate of 1800 hectares (about 4500 ...
- 105: The Rain Forest - Example of a Flourishing Ecosystem
- The Rain Forest - Example of a Flourishing Ecosystem Simply stated the word "ecology" means the relationship of living things to their surrounding and to each other. The rainforest is on of the biggest and best examples of ... it rains, which happens often, this thin topsoil is washed away into the nearest river. This results in a loss of many seeds which have been released from larger plants. Those not lost in the rain can be eaten by such species as agoutis, weevils and other animals. All of these things paint a picture of how hard it is for a seed to germinate and grow into a mature plant ...
- 106: Cyclohexanone
- ... the amount of IR light that was not absorbed. The frequencies are normally listed in wave numbers (in units of reciprocal centimeters). Experiment The oxidation of cyclohexanol by dichromate occurred in the presence of sulfuric acid which yielded cyclohexanone according to the balanced redox reaction below: 3 + Cr2O7-2 + 8H+ -- 3 + 2Cr+3 + 7H2O In the presence of excess dichromate, cyclohexanol oxidizes to adipic acid. To maximize yield, the following reaction was prevented: 3 + 4Cr2O7-2 + 32H+ -- 3HOOC(CH2)4COOH + 8Cr+3 + 19H2O The addition of methanol reduced the excess dichromate according to the balanced redox reaction below: CH3OH + Cr2O7 ... s “Organic Chemistry” has two distinctive absorption’s relevant in this experiment, the aliphatic C-H stretch around 2900 cm-1 and the C=O stretch around 1750 cm-1. The Infrared spectrum for adipic acid below, from McMurry’s “Organic Chemistry” also has two distinctive absorption’s relevant in this experiment, the C=O stretch around 1750 cm-1 and the O-H stretch around 3000 cm-1. The ...
- 107: Lysergic Acid Diethlamide (LSD)
- Lysergic Acid Diethlamide (LSD) LSD or lysergic acid diethlamide is a commonly used drug of teens. LSD is a hallucinogenic drug which effects the nervous system. The drug is ingested in many different ways, absorbed through the skin, taken orally or absorbed through ...
- 108: Black Rain
- ... from the initial "new weapon" through "new-type bomb," "secret weapon," "special new-type bomb," to "special high-capacity bomb." That day, I learned for the first time to call it an "atomic bomb." (Black Rain 282) The importance of the name of the bomb may seem ineffectual, but he seems to dwell on finding out what caused this type of destruction. Something else that Mr. Shizuma wants to do is ... The title has a lot to do with the book because the title is how the whole thing started, with Mr. Shizuma's daughter coming home with black spots on her skin where the black rain had hit her. It could not be washed off and it burnt through clothing. The ending to the novel was satisfactory because the end of the war was a good place to end the novel ...
- 109: Dna Replication
- ... strand; that is, A pairs only with T, and G pairs only with C. Moreover, each set of three bases on a strand, such as AAA, AGC, GGG, or CGT, codes for a specific amino acid (or in the case of a few triplets, for an end to the protein-making process). Thus, a base triplet corresponds to a particular amino acid in the same way that a unit of the Morse telegraph code corresponds to an alphabet letter. In this manner, DNA directs the sequencing of the amino acids that grow into proteins. In many organisms ... the endoplasmic reticulum are the ribosomes, "workbenches" for protein construction. Since the ribosomes are away from the nucleus, the building code must somehow be communicated from DNA to the ribosomes. This is done through ribonucleic acid (RNA). RNA is closely related to DNA and can carry genetic messages. First, DNA unwinds and separates its strands so that complementary strands of RNA can be assembled on them. A strand of so- ...
- 110: Clinical Chemistry Tests In Medicine
- ... glucose and polyuria (excessive urination) results. In order to prevent dehydration, more water than normal is consumed (polydipsia). In the absence of insulin, fatty acids released form adipose tissue are converted to ketone bodies (acetoacetic acid, B-hydroxybutyric acid, and acetone). Although ketone bodies can be used a energy sources, insulin deficiency impairs the ability of tissues to use ketone bodies, which accumulate in the blood. Because they are acids, ketones may exhaust the ... be caused by hemolysis, bile duct obstruction, fever, and starvation (Bistner, 1995). Two important serum lipids are cholesterol and triglycerides. Cholesterol is a precursor to bile salts and steroid hormones. The principle bile salts, taurocholic acid and glycocholic acid, are important in the digestion of food and the solubilization of ingested fats. The desmolase reaction converts cholesterol, in mitochondria, to pregnenolone which is transported to the endoplasmic reticulum and converted ...
