Three Levels 3 M
618 wordsBoats have always represented technological ability and knowledge. And though the Ancient Greeks of Homer's time were not very technologically advanced (relative to the present time), their ships were quite remarkable. The most prominent among the Greek fighting ships was the trireme. The trireme first appeared around 700 BC in Corinth. After years of modification, this Mediterranean galley became the predominant warship from 500 to 300 BC. Controversy arises in trying to describe these ancient ...

Lava Flows Earth Crust
1,090 wordsVolcano: defined is a mountain or hill formed by the accumulation of materials erupted through one or more openings (called volcanic vents) in the earth's surface. The term volcano can also refer to the vents themselves. Most volcanoes have steep sides, but some can be gently sloping mountains or even flat tablelands, plateaus, or plains. The volcanoes above sea level are the best known, but the vast majority of the world's volcanoes lie beneath the sea, formed along the global oceanic ridge sys...

One Problem X 10
1,563 wordsThis essay will critically review some of the major uses of renal micro puncture techniques, focusing in particular on the stationary method, free-flow micro puncture and renal micro perfusion, the latter including both in vivo and in vitro methods. The essay will conclude with a short review of other uses of micro puncture. Were and Richards (1924) were the first people to use micro puncture successfully on the kidney. They successfully inserted a micro pipette into the glomerulus of a single a...

Gulf Of Mexico Tropical Storms
1,204 words... 30 %. A dependent of HRD scientists and technicians remained stationed at NHC to compile catalogs of output from a new storm surge model, the Sea, Lake Overland Surges from Hurricanes (SLOSH). These catalogs mapped possible hurricane flooding and required that each basin be meticulously, numerically rendered. These catalogs were then given to emergency personnel in the target cities to aid in evacuation planning. Computer modeling during the early 1980 's involved work on a 12 level nested g...

Meteor Impact Earth Objects Meteors
589 wordsMeteors are very common throughout outer space. They are being whipped around our solar system in every orbit possible. Normally they are peacefully and serenely floating through space, but one just has to look at the cratered face of our moon or Jupiter's moon Callisto to see that more than a few meteors journeys through space have been interrupted. The earth has been hit before and will be hit in the future, statistics show this. We must detect the meteors a long time before they cross paths w...

Sense Data Space Time
1,315 wordsOne night I saw a TV program, Einstein's Universe. I turned it on because it was narrated by Peter Ustinov, whom I admire, even though I'm tired of Einstein's universe. The program was well done. A great effort was made to make a clear and convincing dramatization of the universe according to Einstein; just enough mystique to sugar the dull sterility of science. What bothered me most was the subservient role of Peter Ustinov playing an average man who didn't know science, feeling privileged to b...

Million Years Ago Hot Spot
346 wordsA hot spot is said to be a volcano that is recognized by an age progression from one end of the chain to the other. An active volcano commonly serves as an "anchor" at one end of the chain. After minutes of searching the web I found a hot spot that was not included in the Hawaii or Yellow Stone hot spots. I found my hot spot near India by the island of About 66 - 68 million years ago present-day India was above the hot spot and great volumes of basaltic lava erupted to produce the Deccan Traps. ...

Left Hand Side Atmospheric Pressure
1,199 wordsChemistry Independent Study: Gas Laws Since the days of Aristotle, all substances have been classified into one of three physical states. A substance having a fixed volume and shape is a solid. A substance, which has a fixed volume but not a fixed shape, is a liquid; liquids assume the shape of their container but do not necessarily fill it. A substance having neither a fixed shape nor a fixed volume is a gas; gases assume both the shape and the volume of their container. The structures of gases...

Gram Negative Petri Dishes
1,384 wordsAbstract/Summary: Changing our focus from the properties and functions that take place within the cell to the actual cell itself, we observed three specific bacterial types within this lab: Gram-positive bacteria, Gram-negative bacteria, and cyanobacteria. We closely observed the features of cyanobacteria and were able to differentiate them from other bacteria. We specifically observed gloeocapsa, merismopedia, anabaena, and oscillator. In addition to this we observed the different characteristi...

An Introduction To Fiber Optics Technology
1,471 wordsThroughout time, speed and efficiency in the telecommunications industry has progressed at a rapid pace due to fiber optic technology. In 1979, AT& T revolutionized the telecommunications industry by producing a medium for data transmission which used light, called fiber optic cable. This medium created a bandwidth of 44. 736 Mbps and could multiplex 672 trunk circuits onto one fiber (Cole, 2000). However, this invention was only the beginning of a great addition to telecommunications, one t...

Log Cabin End Result
1,083 wordsThere are many different campfire structures that can be built to start a fire while camping. The most common are the teepee, log cabin, dugout, and tunnel structures. Almost anyone can build these fires if he or she follows some key points. A fire needs three elements: air, fuel, and an ignition of some kind. For a campfire the air element is easily accessible; its the air a person breaths or oxygen. Fuel is equivalent to wood. Sometimes lighter fluid is used to start big fires immediately, but...

This is a type of microscope that makes use of a beam of electrons rather than visible light. Because the wavelength of electrons is much smaller than the wavelength of visible light, an electron microscope not only gives a high magnification but it also has high resolution. This means that details can be seen clearly. An electron mic...

Time It Takes Surface Of Mars
1,058 wordsMars is the fourth planet from the sun at about 228 million-km (141 million miles) and the last terrestrial planet from the sun. The next five planets in order from the sun are gaseous. Mars follows closely behind Earth but is comparatively smaller, with about half the diameter of Earth and about one-tenth of Earth s mass. Thus the force of gravity on Mars is about one-third of that on Earth. Though it is much smaller, Mars does have the same surface land area as Earth. Other than Earth, Mars po...
