Trace Evidence
Trace Evidence Trace evidence is very important in forensic investigations. This category of evidence encompasses many diverse types of microscopic materials as well as some examples that are easily visible to the naked eye. The subject is broad and diverse because of the number of different types of evidence that are commonly encountered. Trace evidence can be thought of as evidence occuring in sizes so small that it can be transferred or exchanged between two surfaces without being noticed. V

PLATE TECTONICS PAPER In 1912 Alfred Wegener, a meteorologist, revived a theory that the continents of the eastern and western hemispheres were once joined. Wegener, along with his followers showed how the east coast of the Americas align with the westside of the Old World, a coincidence that Leonardo da Vinci commented upon. But no one could come up with a convincing way to push, shove, or drift whole continents for thousands of kilometers. It was thought that the deep granite continental mass

One Of The Earliest Inventions Of The Ancient World, The Candle Is Sti
One of the earliest inventions of the ancient world, the candle is still favored for the beautiful light cast by its flame. In its most basic form the candle consists of a cylinder of wax, tallow, or similar material surrounding and saturating a fibrous wick. Ancient Egyptian tombs at Thebes bear relief carvings of cone-shaped candles on dish-like holders, or candlesticks. The oldest known candle fragment was found at Vaison, near Avignon, in France and dates from the 1st century AD. During the

THE EFFECTS OF ALTITUDE ON HUMAN PHYSIOLOGY Changes In Altitude Have A
THE EFFECTS OF ALTITUDE ON HUMAN PHYSIOLOGY Changes in altitude have a profound effect on the human body. The body attempts to maintain a state of homeostasis or balance to ensure the optimal operating environment for its complex chemical systems. Any change from this homeostasis is a change away from the optimal operating environment. The body attempts to correct this imbalance. One such imbalance is the effect of increasing altitude on the body's ability to provide adequate oxygen to be utiliz

Radioactive Wastes, Must For The Protection Of Mankind Be Stored Or Di
Radioactive wastes, must for the protection of mankind be stored or disposed in such a manner that isolation from the biosphere is assured until they have decayed to innocuous levels. If this is not done, the world could face severe physical problems to living species living on this planet. Some atoms can disintegrate spontaneously. As they do, they emit ionizing radiation. Atoms having this property are called radioactive. By far the greatest number of uses for radioactivity in Canada relate n

Solar Cells Today Are Mostly Made Of Silicon, One Of The Most Common E
Solar cells today are mostly made of silicon, one of the most common elements on Earth. The crystalline silicon solar cell was one of the first types to be developed and it is still the most common type in use today. They do not pollute the atmosphere and they leave behind no harmful waste products. Photovoltaic cells work effectively even in cloudy weather and unlike solar heaters, are more efficient at low temperatures. They do their job silently and there are no moving parts to wear out. It

The art of design is not only rooted in the aesthetic form, but in the soul of the work. In Phenomena and Idea, Stephen Holl once wrote, The thinking-making couple of architecture occurs in silence. Afterward, these thoughts are communicated in the silence of phenomenal experiences. We hear the music of architecture as we move through spaces while

The safety issues discussed focus on the inspection of Boeing 747 engine pylons, meteorological hazards to aircraft, the lateral load-carrying capability of engine pylon structures, and aircraft departure routes at Anchorage International Airport during turbulent weather

Epoxy Resins Epoxy resins The group of synthetic resins called epoxies produce the strongest adhesives in current use, as well as plastics and corrosion-resistant coatings. Epoxy adhesives are thermosetting; that is, after initial hardening, they cannot be remelted by heat. They have excellent resistance to solvents and weathering agents, and high electrical and temperature resistance. Their adhesion to almost any type of surface--including metal, ceramic, wood, and fabric--is unmatched. Epoxies

Nearly every individual has his or her own idea of what our universe is. During our modern era of advanced scientific knowledge, we feel that we have a good grasp on how the universe works. We have our Chemistry and Physics, along with Mathematics, to examine the universe with. Any person educated in these fields will tell you that they

Flight Research: Airplanes are an efficient way of traveling to far places. Airplanes are amazing if you know what and how the air keeps the plane airborne. There are three components of flight: aerodynamics, the Bernoulli principal and supersonic flight. Some other things about flight are the four forces, lift, drag, weight, and thrust. One of the basic things you need to know about airplanes is that the places where the plane can balance on one point called the center of gravity. The tail on t
