- Biomass - 1,670 words
Biomass Many factors contribute to the diversity of life in an environment. The availability of nutrients and sunlight, along with other factors that play a pivotal role in determining what and how much life an area can sustain. While studying the Second Law of Thermodynamics, it came to my attention that the classical pyramid shape of the producer, C1, C2, C3, biomass pyramid did little to take into account the amount of detrital input. I hypothesized that the amount detrital input greatly effected the number of C1, C2, and C3 consumers and thus the overall biodiversity of an ecosystem. Further, if you could find a test-bed where detrital input was the only real difference between two simil ...

- Brisbane River - 1,955 words
Brisbane River 1.0 INTRODUCTION The Brisbane River has flowed for over 400 million years. The catchment of the Brisbane River has overcome phases of flood and drought while its origins altered as the surrounding land changed overtime. In 1823, John Oxley entered the river for the first time. At the time the river appeared clean and unpolluted. Oxley immediately recognised the river's potential as a site for new settlement, through his recommendation the city of Brisbane was established in 1825. The Brisbane River extends inland for 300km reaching its source at the foothills of the Great Dividing Range. The river's catchment occupies an area of approximately 30,000km2 and releases it waters i ...

- Cancer Treatment - 1,837 words
Cancer Treatment There are many ways to treat cancer. In fact, when you enter "cancer treatments" into any web browser you will find millions of web sites on how to treat cancer. Some examples of these treatments are chemotherapy, oxygen therapy, vitamin D therapy, food therapy, immunotherapy, and many others. Certain types of therapies go with certain types of cancers. For example, vitamin D therapy goes with breast cancer and immunotherapy goes with colon cancer. Cancer has taken the lives of millions of people and I believe it is important to inform people of what treatments are circulating in the medical profession. The human genome project's goal is to map and sequence the tens of thous ...

- Concentrations On Maximal Exercise Capacity Or Ventilation In Stable Heart Failure - 757 words
Concentrations On Maximal Exercise Capacity Or Ventilation In Stable Heart Failure Critical Inquiry 10/31/00 The goal of the article, (Lack of Effect of Increased Inspired Oxygen Concentrations on Maximal Exercise Capacity or Ventilation in Stable Heart Failure. The American Journal of Cardiology, 84(12), Dec.15, 99. pp 1412-1416.) is to further study the effects of administration of increased inspired oxygen concentrations on maximal exercise capacity and exercise ventilation in heart failure. Recent uncontrolled studies have suggested improvement on maximal exercise capacity and a decreased exercise ventilation. This study used 21% as normal and 60% as increased inspired oxygen concentrati ...

- Earth Summary - 430 words
Earth Summary Earth An Inner Terrestrial Planet Size: About 8,000 miles in diameter Distance: 1 A.U. from the Sun Day: About 24 hours Year: About 365 days General Description: Earth may be the most unique of all planets because of the life forms we know exist here and the way they utilize the Suns energy. The Earth is composed of a great amount of water, mostly in the form of oceans, which make up most of its surface. It also contains various gases, of which make it possible for us humans to exist and is a system that exists between plants and animals here. Core/Interior: The Earth has three layers to it's interior, the inner core, outer core, and mantle. Of these the outer core is thought t ...

- Fish Gills - 562 words
Fish Gills Not all animals have lungs. Many animals live in environments where lungs would be efficient enough for survival. Gills are another type of respiratory system, which are very efficient at removing oxygen from water: there is only 1/20 the amount of oxygen present in water as in the same volume of air. Gills greatly increase the surface area for gas exchange and they occur in a variety of animal groups including arthropods (including some terrestrial crustaceans), annelids, fish, and amphibians. Gills are typically comprised of a gill arch, which contain veins and arteries that supply blood flow to the attached gill filaments. The arches are a rigid stucture which provide support a ...

- Freshwater Regions - 1,507 words
Freshwater Regions Freshwater is defined as having a low salt concentrationusually less than 1%. Plants and animals in freshwater regions are adjusted to the low salt content and would not be able to survive in areas of high salt concentration (i.e, ocean). There are different types of freshwater regions: ponds and lakes, streams and rivers, and wetlands. The following sections describe the characteristics of these three freshwater zones. Ponds and Lakes These regions range in size from just a few square meters to thousands of square kilometers. Scattered throughout the earth, several are remnants from the Pleistocene glaciation. Many ponds are seasonal, lasting just a couple of months (such ...

- Ozonification In Water Treatment - 267 words
Ozonification In Water Treatment Ozonification in Water Treatment Report Ozone is nature's agent for cleaning and treating both air and water. That clean fresh smell in the air following a thunderstorm, the bright sky and brilliant colors of nature are due to ozone - created by lightning and the Sun's energy. Ozone is a gas that is created naturally in our atmosphere when oxygen in the air is exposed to high intensity ultraviolet rays. Both the sun and lightning create the ozone. Ozone is also one of nature's best bleaching agents, restoring discolored water to its naturally clear state. As an oxidizer and microflocculant, it also helps reduce unwanted organic material form water, such as ir ...

- Sulfuric Acid Industry In Ontario - 1,026 words
... o electrons lost by the hydrogen atoms, thus becoming negatively charged (SO4--). These groups can combine with others of opposite charge to form other compounds. The lead-acid cell uses sulfuric acid as the electrolyte. The lead-acid storage battery is the most common secondary battery used today, and is typical of those used in automobiles. The following will describe both the charging and discharging phase of the lead-storage battery and how sulfuric acid, as the electrolyte, is used in the process. The lead storage battery consists of two electrodes or plates, which are made of lead and lead peroxide and are immersed in an electrolytic solution of sulfuric acid. The lead is the anode ...

The History Of Carbon The History of Carbon I. Introduction A. The History of Carbon II. Occurrences in Nature A. Diamond B. Graphite C. Coal and Charcoal D. Amorphous Carbon III. Carbon Compounds A. Inorganic B. Organic IV. The Carbon Cycle IV. Conclusion Carbon, an element discovered before history itself, is one of the most abundant elements in the universe. It can be found in the sun, the stars, comets, and the atmospheres of most planets. There are close to ten million known carbon compounds, many thousands of which are vital to the basis of life itself (WWW 1). Carbon occurs in many forms in nature. One of its purest forms is diamond. Diamond is the hardest substance known on earth. Al ...
