Analysis On Electronic Data Imaging

... and manageable market segments. From initial exploratory research using primarily secondary resources we have developed the following overall market analysis: Digital Imaging Conversion Services Much to the dismay of many in the business world, the arrival of the "paperless office" has been slow coming. Even though the technology exists to almost eliminate paper documents, many businesses have never heard about it. This technology is collectively known as Document Imaging. Imaging has evolved out of the necessity for businesses to man ...

The Influence Of Writers On Charles Darwin

... and provided substantial proofs and he related various branches of science such as geology, botany and biology which helped validate his theories. His theory of natural selection as stated by Nelson and Jurmain (1991, p.606) in the modern form is that "the evolutionary factor causes changes in allele frequencies in populations due to differential net reproductive success of individuals." His grasp of the evolutionary process and the clarity of his work makes Charles Darwin the most popular figure in the scientific field of Evolutio ...

Acupuncture

... imbalance, resulting in disease is the aim of traditional Chinese diagnostic procedures. These involve a precise, sequential consideration of data, obtained by clinical observations, interrogation to obtain a detailed case of history, and palpation of the pulses. There are three main methods of diagnosis that are employed in the clinic: looking, asking and palpating, all of which contribute to a full and accurate diagnosis of the patient’s condition. By looking at the patient’s face, body and movements, the practitioner is already beginn ...

Limonene And Its Uses

... pesticides for reregistration, EPA obtains and reviews a complete set of studies from pesticide producers, describing the human health and environmental effects of each pesticide. The Agency imposes any regulatory controls that are needed to effectively manage each pesticide's risks. EPA then reregisters pesticides that can be used without posing unreasonable risks to human health or the environment. When a pesticide is eligible for reregistration, EPA announces this and explains why in a Reregistration Eligibility Decision (RED) ...

Global Warming 2 --

... surface and warms it even more. Some of the naturally occurring greenhouse gases are Methane and carbon dioxide. This is the way the Earth keeps itself warm enough for humans to live on it. The only problem with this is that humans enhance the process even more. Over the past 200 years the emissions of greenhouse gases have been increasing due to the increase in technology that humans have developed (example, factories). These human-induced gases include carbon dioxide, methane, nitrous oxide, and ozone depleting substances such as CFCs ...

Mitochondrion

... organelles are not a true organelle, but more of a parasite that invaded primordial cells and evolved along with them. A mitochondrian’s main purpose is to burn energy through a slow method of combustion, which will consume as much air to burn as fire will, just to break down nutrients into simpler substances. These simpler molecules then bond with the atoms that will need the energy to function. Then, enzymes in the mitochondrion break up the atoms and then recapture them again. This time, the energy atoms will be bonded in a diff ...

Alternative Fuel Source

... the soil in which it grows, without chemical fertilizers, while choking out weeds by virtue of its fast dense growth. According to the U.S. Department of Agriculture, over a twenty year period one acre planted with hemp produces as much pulp as 4.1 acres of trees. Farming hemp at such a fast rate is the key to providing large enough amounts of raw biomass at costs low enough to enable cellulose (the hydrocarbon provider necessary for fuel production) to recapture lost markets. This versatility has led people to believe it is the only biomas ...

Great White Sharks

... sharks, and every summer and fall, they actively feed in nearshore areas. The Farallan Islands, a national wildlife refuge about twenty-seven miles off San Francisco, is a common feeding ground for the great white. The coastal waters along central California, especially around the Ano Nuevo State Reserve and along the Marin Headlands, are another common area for white sharks. In the summer the sharks move to the coasts of Oregon and occasionally the Gulf of Alaska, and in the fall, they turn south and move along the ...

Deforestation

... is a significant issue of our time and must be taken seriously if we want to protect our remaining forests. The definition of deforestation by the Random House Dictionary of the English Language is "to divest or clear of forests or trees" and we must stop deforestation to save our planet. My intent on writing this essay is to enlighten the reader about the facts on deforestation and to express my opinions about deforestation. There are approximately 3 400 million hectares of forests in the world, nearly 25% of the world's land area. Clo ...

Aurora Borealis

... charged particles from the sun enter the Earth's atmosphere. This stream of particles, a form of plasma, is carried away from the sun by the solar wind. As the plasma approaches Earth, it is trapped for a time in the outermost parts of the Earth's magnetic field, an area called the Van Allen belts. Eventually the plasma is drawn down toward the North and South magnetic poles. Along the way, it ionizes (creates an electric charge within) the oxygen and nitrogen gas it encounters in the atmosphere, causing it to glow. The flow of plasma fro ...

Could The Greenhouse Effect Cause More Damage?

... steel towers, one at each corner of the grid. Hanging down from the cables are ten infrared heat lamps which are about three feet long each. This is supposed to simulate what many see as the coming apocalypse. (global warming) "By 2050, if we decide to load trace gasses - mainly carbon dioxide - into the atmosphere at our current rate, we can expect Earth's temperature to increase by any-where from three to nine degrees. The Vostok record confirms that," says Harte. The grid is divided into ten sections. Each of the ten sections c ...
