The Nuclear Power Debate

... power provides 17% of the world's electricity but coal is the main source, making up 39%. However, fossil fuels such as coal, require greater quantities to produce the equivalent amount of electricity produced from Uranium. The use of nuclear power opposed to burning fossil fuels has reduced carbon dioxide emissions by 2 billion tonnes per year, minimising the global warming effect on the atmosphere. Carbon dioxide is responsible for half of man made gases contributing to the Greenhouse Effect, and has sparked action from the UN ...

Aedes Aegypti

... to moisture, lactic acid, carbon dioxide, body heat and movement (E.B. 1999) but we can not confuse the Aedes aegypti with any other mosquito for it has a very distinct look to it as well as a specific habitat. It has many related species and it’s geographic distribution is extremely wide and varied. The Aedes aegypti, with regard to both sexes, are generally similar in coloration (Womack 1993). The female adult is noticed by it’s small dark figure that is colored by white markings and banded legs. Its proboscis or snout is ...

Hurricanes

... how this happens. But when it does, it's the first step in the birth of a hurricane. With the lid off, the warm, moist air rises higher and higher. Heat energy, released as the water vapor in the air condenses. As it condenses it drives the upper drafts to heights of 50,000 to 60,000 feet. The cumuli become towering thunderheads. From outside the storm area, air moves in over the sea surface to replace the air soaring upwards in the thunderheads. The air begins swirling around the storm center, for the same reason that the air swirls aroun ...

Cosmology

... the topics that covers. Personally, I tend to believe that the big bang theory may have an explanation for the current state of our universe. The idea that all of this exploded from a super mass isn’t too hard to believe. It gives good reason to the expansion of the universe, and the 360degree view of the universe (this because the explosion would have sent mass outward in every direction), but I wouldn’t think of it as the origin of the universe. I mean, in my mind, something had to be there to cause this super mass. Was the universe c ...

Facts About Orthoptera

... live in wet grassy areas. Locust also contribute to Orthoptera. Locust plagues have been recorded since the beginning of history and are still one of the worlds major insect problems. Cockroaches are in this group too. Their are an estimated 3,000 cockroach species in the world. About 55 live in the U.S., and only 4 species ar common household pets. German cockroaches or Croton bugs, are common in the U.S. especially in the northern states. They commonly enter the house in bags or boxes from grocery stores. They tend to cluster in warm m ...

The Choosing Of A Landfill Site

... used classification of landfills, according to waste type only, is described below, together with a classification according to landfill strategy. The EU Draft Landfill Directive recognises three main types of landfill: Hazardous waste landfill Municipal waste landfill Inert waste landfill Similar categories are used in many other parts of the world. In practice, these categories are not clear-cut. The Draft Directive recognises variants, such as mono-disposal - where only a single waste type (which may or may not be ha ...

Wilderness Required

... the AIDS virus without the rare vegetation of the rainforests. Today’s technology can produce any concoction imaginable; though most are developed by duplicating and improving what nature has to offer. As long as there are natural discoveries yet to be made, then there are cures only yet to be discovered. A trek to the peak of a snow-capped mountain or an Arctic voyage through glaciers and icy waters are the journeys that most would consider essential to life. Colin Fletcher was one to claim that wilderness is needed: “And when at last ...

Surface Tension

... the surface tension of water. The razor blade is not floating: if pushed through the surface, it sinks through the water. More specifically, the tension is the force per unit length of any straight line on the liquid surface that the surface layers on the opposite sides of the line exert upon each other. The tendency of any liquid surface is to become as small as possible as a result of this tension, as in the case of mercury, which forms an almost round ball when a small quantity is placed on a horizontal surface. The near-perfect spherical ...

The Future Of NASA

... may even be considering ways to alter life on Mars, so that people would be able to live there some day. Some products developed in NASA's space program that we now incorporate in our daily lives include the vacuum cleaner, pacemaker, pens that can write upside-down, and the zero-gravity training system. The vacuum cleaner was originally a great tool for astronauts in outer space. It is now a very helpful tool for cleaning our homes. The pacemaker is a form of life-support on spacecrafts, helping astronomers' hearts pump while they are o ...

The Prospect Of Cold Fusion

... not be surprising if you thought that cold fusion was "dead," because the scientific establishment, the hot fusion community, and many in the news media have ignored the continuing cold fusion research. But cold fusion is far from dead. It is alive not only in dozens of laboratories in the United States, but in numerous foreign research centers, particularly in Japan. Cold fusion is a real but still incompletely explained energy-producing phenomenon that occurs when ordinary hydrogen and the special form of hydrogen called deuterium are broug ...

The Formation Of Rocky Shores

... sediment. Eastern Canada and New England were once covered by ice, which scraped away the sediment from the continental shelf and exposed the bare rock below. The coasts sank due to the tremendous weight of the ice and when the ice melted the coasts had rebounded or slowly rose. The bare rock had become the new coastline. Other shores had developed from geological events but in a different way. The rocky coast of Hawaii was formed by successive flows of lava into the sea which have not had time to collect sediment. Life on the ro ...
