Although all Basking sharks are large, the females tend to be quite a bit bigger than the males, which is probably because they have to carry a whole other organism within (Harman, 1996, 21). Basking sharks have, at some point in time, also been known as the elephant shark, the Bon ...

Electronics- Logic Probe

... the black goes to the ground. The input enters from pin 6 and 2 of the 555 IC. If the voltage is LOW, the bottom LED lights. If the input voltage is HIGH, the top LED lights. When the input probe is disconnected, both LEDs light. Note that pin 3 of the 555 IC always goes to the opposite logic level of the input. Therefore, if the input is HIGH, the output of the 555 IC, which is pin 3, goes LOW. This in turn activates and lights the top LED (the HIGH indicator). Logic probes derive their operating power from the PCB under test. Care should be ...

Solar Energy - The Energy Of The Future?

... absorb heat more efficiently. However this method only supplies enough energy for activities such as washing and bathing. The solar panels generate "low grade" heat, that is, they generate low temperatures for the amount of heat needed in a day. In order to generate "high grade" heat, intense enough to convert water into high-pressure steam which can then be used to turn electric generators there must be another method. The concentrated beams of sunlight are collected in a device called a solar furnace, which acts on the same princip ...

Lipids

... can find lipids in many places. They are usually in fatty foods like butter, salad dressing, and cooking oils. They can also be found inside of animals as the form of fat. Lipids are always found in fat because when you get a build up of lipids it forms fat. Lipids have many uses amongst plants and animals. The main use of these are for energy and storing energy. When they store energy they make triglycerides also known as fat. There are also many other uses such as insulation and protection. They are also used in making cell membr ...

Tiger Subspecies

... say that the number of Sumatra tigers today is between 300 and 400, it doesn't tell one that the 1975 census was 1500. Therefore saying that the Bali tiger, theCaspian tiger, the Javan tiger, the Manchurian tiger, and the Southwest Chinese tiger are now extinct doesn't give you aportrait of the process of extinction. The Javan tiger became extinct in the 1970's in a set aside special national park under full protection. Politicans and bureaucrats seem to be obsessed with numbers and not trends. Let me illustrate this with tigers. There are f ...

Barrier reefs lie farther offshore, separated from land by lagoons more than ten meters deep. Atolls, on the other hand, are formed far offshore and they make a ring-shaped reef that close a circular lagoon. Coral reefs a ...
