Thoughts On Acid Rain

... and trucks are the main sources for nitric acid(about 40% of the total), while power generating plants and industrial commercial and residential fuel combustion together contribute most of the rest. In the air, the sulphur dioxide and nitrogen oxides can be transformed into sulphuric acid and nitric acid, and air current can send them thousands of kilometres from the source.When the acids fall to the earth in any form it will have large impact on the growth or the preservation of certain wildlife. NO DEFENSE Areas in Ontar ...

Circus Animals

... Florence Lambert. When traveling, animals spend hours, even days between sites in confinement. Even when they are not traveling relief facilities for animals to exercise and play. A water supply is not always readily available in all locations, leaving many animals with out water. Furthermore, with out water, cleaning becomes a low priority. This is very hard on animals especially elephants who bathe frequently in their natural environment. But, the circus environment is very different from an animal’s natural habitats. Summer c ...

Ecommerce

... Almost each and every superstore has their web site and facility to their customers to buy products online. In the 21st century each and every individual among us will be running out of time and nobody wants to go out to shop and waste 4 to 5 hours rather every one of us would prefer to shop online at the same price and get delivered at our door step. The electronic retail marketplace demands the highest attention to visual graphic design quality, coupled with the ability to construct an electronic catalog. This catalog must support mult ...

Cells

... The DNA of a cell is found in the nucleus along with RNA. The nucleus is surrounded by two membranes due to the need to be highly selective with materials that enter the cell's nucleus. The cell itself is surrounded by a membrane. In between the membrane of the nucleus and the cell membrane is cytoplasm. It is in the cytoplasm where all of the other organelles are stored. There are six main organelles in the cytoplasm. First, the mitochondria, which provides energy to the cell through ATP and respiration. Then there is the endoplasmic re ...

Bioluminescence In Fungi

... of a bioluminescent fungi is displayed in figure 1). One of the features of biological light that distinguishes it from other forms of light is that it is cold light. Unlike the light of a candle, a lightbulb, bioluminescent light is produced with very little heat radiation. This aspect of bioluminescence especially interested early scientists who explored it. The light is the result of a biochemical reaction in which the oxidation of a compound called "Luciferin" and the reaction was catalyzed by an enzyme called "Luciferase". The light ge ...

Effects Of Secondhand Smoke

... bronchitis and pneumonia in infants and children under 18 months of age every year from secondhand smoke. Children from birth to 2 years of age are especially vulnerable to lung diseases because their lungs are not fully developed. Asthma is more likely to develop with children who breathe secondhand smoke (www.alaw.org). It can also exacerbate frequent attacks. Babies are three times more likely to die form Sudden Infant Death Syndrome (SIDS) if their mothers smoke during pregnancy. Ear infection, coughs, sore throat and even cancer can also ...

Daltons Atomic Theory

... the results of those experiments, Dalton developed the hypothesis that the sizes of the particles making up different gases must be different. Dalton's exceptional gift for recognizing and interpreting patterns in experimental data lead him from a problem in meteorology to the idea of atoms as fundamental constituents of matter. He realized the vital theoretical connection between atomic weights and weight relations in chemical reactions. He was the first to associate the ancient idea of atoms with stoichiometry. The existence of atoms w ...

Preserving Our Earth

... Many believe that our secluded wildlife areas should be available for the public. But what is to be offered through this? Many recreational activities I presume, but what about our biggest environmental concern - pollution. Pollution is so widespread throughout our world that it is overwhelming. Drinking water supplies are contaminated with runoff from nearby factories and even with pollutants from our own backyards. Demands of skyscrapers and condominiums wipe out our decreasing rainforests. This drudges wildlife from its n ...

Internet Security 2

... problem because they thought about just how vulnerable we are; from bank records and accounts to their driving history and insurance information. There have been countless cases of breaches in security, including theft of money, because of the lack of security on the Internet. I feel that the need for greater security measures on the net is increasing as we move towards the millennium and bigger security problems are created as we depend on computers more and more everyday. Computer Systems these days are protected in one of two ways, or b ...

Environmental Protection

... efforts to protect endangered species invariably point this out. They also suggest that the role of homo sapiens in causing extinction should not be distinguished from that of any other species. This position, most often espoused by individuals whose other views are curiously much more anthropocentric, is contrary to some well established facts. Unlike other creatures that have inhabited the Earth, human beings are the first to possess the technological ability to cause wholesale extermination of species, genera or even entire families ...

Bipolar Disorder 4

... have committed suicide. This rate is nearly 30 times greater than that of the general population. Research suggests that people who commit suicide, whether depressed or not, tend to be more impulsive in their behavior. Manic-depressives, due to their spontaneous nature, are more likely to commit suicide than depressives. Manic depression involves alternating episodes of serious mania and depression. An affected person’s mood can swing from excessive highs (mania) to deep hopelessness (depression), usually with periods of normal m ...

Gold And Its Uses

... the flow of charged particles in a current, metals that are conductive allow this current to flow unimpeded. "Gold is able to convey even a tiny electrical current in temperatures varying from -55° to +200° centigrade." (Gold Institute) Gold is the most ductile of all metals, allowing it to be drawn out into tiny wires or threads without breaking. Consequently, a single ounce of gold can be drawn into a wire five miles long. Gold's malleability is also unparalleled. It can be shaped or extended into extraordinarily thin sheets. For example ...
