... calculating machine". It could only add numbers and they had to be entered by turning dials. It was designed to help Pascal's father who was a tax collector.
In the early 1800's, a mathematics professor named Charles Babbage designed an automatic calculation machine. It was steam powered and could store up to 1000 50-digit numbers. Built in to his machine were operations that included everything a modern general-purpose computer would need. It was programmed by--and stored data on--cards with holes punched in them, appropriately called "punchcards". His inventions were failures for the most part ...

... : 1 megahertz = 106 hertz, 1 gigahertz =
109 hertz). All radio waves fall within a frequency range of 3 kilohertz, or
3000 cycles per second to 30 gigahertz. Within the range of frequencies, radio
waves are further divided into two groups or bands such as very low frequency (
VLF 10-30 kHz ), low frequency (LF 30-300 KHz), medium frequency ( MF 300-3000
KHz), high frequency ( HF 3-30 MHZ) and very high frequency ( VHF 30-300MHZ).
Amplitude modulation is the oldest method of transmitting voice and
music through the airwaves is by amplitude modulation. This is accomplished by
combining a sound wave ...

... impact on the growth and the preservation of certain wildlife. These substance's can neutralize acids entering the body of water, thereby protecting it. However, large areas of Ontario that are near the Pre-Cambrian Shield, with quartzite or granite based geology and little topsoil; there is not enough buffering capacity to neutralize even small amounts of acid falling on the soil and the lakes. Therefore over time, the basic environment shifts from an alkaline to an acidic one.
Air Pollution, contamination of the atmosphere by gaseous, liquid, or solid wastes or by-products that can endanger huma ...

... America Online (AOL), Prodigy, and Compuserve, where consumers are able to check airline flight schedules and make reservations, purchase a wide variety of products, and discuss product performance with other consumers, are becoming very popular. Households in Chicago and San Francisco can purchase groceries from home using computer software marketed by Peapod, Inc. This latter service allows consumers to search within a product category using attributes such as price, calories, sugar content, and package size. Car manufacturers such as BMW regularly mail CD-ROMs to potential customers with video sh ...

... respond to initial drug treatment programs and treats both the positive and negative symptoms of schizophrenia (Advokat et al., 1999; Robinson et al., 1999). Moreover, a reduction in negative symptoms has also been noted to occur as individuals are treated with amisulpride and (Danion et al., 1999). The use of newer drugs to treat schizophrenia has produced fewer side effects in most patients. However, it has been found that although the use of risperidone to treat patients is very effective in treating the symptoms, there may be negative side effects for women using the drugs (Caracci,1999). As w ...

... is usually the first type of gas consumed in a
star and then other gas elements such as Carbon, Oxygen, and Helium are consumed.
This chain reaction fuels the star for millions, or billions, of years
depending upon the amount of gases there are. The star manages to avoid
collapsing at this point because of the equilibrium achieved by itself. The
gravitational pull from the core of the star is equal to the gravitational pull
of the gases forming a type of orbit, however when this equality is broken the
star can go into several different stages. Usually if the star is small in mass,
most of th ...

... stem cells. Scientists have used such mouse stem cells for nearly a decade to create genetically altered mice (Travis Par. 8). Kaye Tucker of World Socialist Web Site writes, “These basic cells are present in the earliest stages of developing embryos and are able to develop into virtually any type of cell and tissue in the body” (Par. 3). This is where genes can be altered and clones can be made. It has been a hard task locating and being able to work with these stem cells because they are only around for a short time (Tucker Par. 6). The possibilities for new research are endless.

Mineralocorticoids steroids control the overall body fluid. Mineralocorticoids are critical to regulate concentrations of minerals in extracellular fluids. The major target of aldosterone is the distal tubule of the kidneys. There it stimulates the exchange of sodium and potassium. It reaches the target goal by the distal tubule of the kidneys.
