... close to the sun, and has no substantial atmosphere, it has the greatest temperature range of any planet or natural satellite in our solar system. The surface temperature on the side of Mercury closest to the Sun reaches 427 degrees Celsius, a temperature hot enough to melt tin. On the side facing away from the Sun, or the night side, the temperature drops to -183 degrees Celsius. Scientists have detected a magnetic field surrounding Mercury, though it is not as strong as the field around the Earth. Scientists theorize that Mercury's field is due to an iron-bearing core or possibly to the solar winds. Mercury's atmosphere is very thin and is composed of helium ...
... that there is nothing to be afraid of and that there is no possibility of a major accident. They take the public's biggest fears, meltdowns and contaminations, and make them into "events" and "infiltrations." This use of doublespeak is misleading to the public and may make them believe that a major accident hasn't happened, or the accident was a normal event or minor incident. In 1979 a valve in the Three Mile Island stuck open, allowing coolant, an important part of the plant, to escape from the reactor. An installed emergency system did its job and supplied the reactor with necessary coolant, but the system was shot off for a few hours due to employee error. Co ...
... of Arizona in Tucson. "This is just our first tentative glimpse into the very remote universe," says Alan Dressler of the Carnegie Observatories in Pasadena, CA. "What we see may be the first stages of galaxy formation. But the objects are so faint that their true nature can only be explored with the advanced telescopes of the future." "This observation is a major step toward fulfilling one of Hubble's key objectives: to search for the faintest and farthest objects in the universe," adds Ed Weiler, NASA's acting Associate Administrator for Space Science. In a separate discovery, Thompson also found that faint red galaxies matched up with compact blue knots of ...
... tube to the closed end, where it is reflected. the wave has now completed a single cycle. It has passed through the tube four times making the closed tube, one fourth the length of a sound wave. By a continuous sound frequency, standing waves are produced in the tube. This creates a pure tone. We can use this knowledge of one fourth wavelength to create our own demonstration. It does not only have to be done using wind, but can also be demonstrated using tuning forks. If the frequency of the tuning forks is known, then v=f(wavelength) can find you the length of your air column. Using a tuning fork of frequency 512 c/s, and the speed of sound is ...
... collapse of a star, usually having a great, massive, core. A star is created when huge, gigantic, gas clouds bind together due to attractive forces and form a hot core, combined from all the energy of the two gas clouds. This energy produced is so great when it first collides, that a nuclear reaction occurs and the gases within the star start to burn continuously. The Hydrogen gas 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 av ...
... for targeted research to try to explain these occurrences. "It may be valuable to carefully evaluate UFO reports to extract information about unusual phenomena currently unknown to science," the report stated, adding that such research could also improve understanding of, and in some cases debunk, supposed UFO events. For example, Earth science researchers have eventually accepted several phenomena "originally dismissed as folk tales," including meteorites and certain types of lightning, the panel noted. The findings are from a four-day workshop held in Tarrytown, N.Y., followed by a second three-day meeting in San Francisco, both last fall. The results are ...
... result in the inheritance of a behavior. One of the most famous of experiments that illustrates classical conditioning is Pavlov's Dogs. In this experiment, Pavlov sat behind a one-way mirror and controlled the presentation of a bell. The bell was the conditioned stimulus. A conditioned stimulus was an originally neutral stimulus that could eventually produce a desired response when presented alone. Directly after the ringing of the bell, Pavlov gave the dog food. The food was the unconditioned stimulus. This means that the food caused an uncontrollable response whenever it was presented alone. That response would be the salivation of the dog. A tube that w ...
... is ingested orally and is rapidly and completely absorbed into the gastrointestinal tract. It works in about one hour. The liver detoxifies 90% of it by mixing it with sulfuric acid, and another 3-5% is catabolized by enzyme reactions to the acid. The metabolites are excreted in the urine. The dosage of the drug should be used according to the carton instructions. A 10 gram over dose in adults, 140 mg for kids, can cause permanent liver damage. Also if you had just taken some other drugs , The may become more toxic since the drugs are catabolized in the liver. To protect yourself from injury, you should take 1 gram of vitamin C and Cysteine -a bodily a ...
... Barclay, an anti-materialist, greatly influenced Owen. Through Barclay's recommendation of Owen to John Abernathy, President of the Royal College of Surgeons, Owen was granted membership to the Royal College in 1826. Owen was later appointed assistant in the cataloging of a collection containing thirteen thousand specimens (known as the Hunterian Collection (Rupke 17)). It was probably this that lead Owen interest in the field of anatomy, which eventually lead him into becoming a naturalist. By 1836, he published anatomical work on the Memoir on the Pearly Nautilus (Rupke 119). Within a year, he was giving lectures to the public on the the Hunterian Col ...
... 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 mostly black with regard to the white palp tips (Russel 1996). The dorsal pattern of white scales on the scutum is in the shape of a ‘lyre’ with two central based stripes that contrast with the dark scales present on the insect (Womack 1993, Russel 1996). Its wings are dark scaled and femur and hind legs are pale scaled for about three-quarters, and dark scaled for about two-thirds (Russel 1996). The first through the fourth segments of the hind tarsi are ...
