Drug Identification With Gas Chromatography Mass Spectrometr

... methods for identifying chemical substances, and the two instruments have be coupled together to perform a highly complementary analytical function. The gas chromatograph and the mass spectrometer have theories behind how their techniques work, and specific forensic applications for their instrumentation. The history and theory of the gas chromatography started over forty years ago with the invention of the capillary column. The gas chromatograph offers rapid and very high-resolution separations of a very wide range of compounds, with the o ...

Growth Dynamics Of E. Coli In Varying Concentrations Of Nutrient Broths, PH, And In The Presence Of An Antibiotic

... nutrient broths of varying pH levels: 6.0, 7.0, and 8.0; and finally a nutrient broth in the presence of the drug/antibiotic chloramphenicol. A variety of OD readings were taken and calculations made to determine the number of cells present after a given time. Then two graphs were plotted, Number of cells per unit volume versus Time in minutes and Log of the number of cells per unit volume versus Time growth curve. The final cell concentration for the control was 619,500 cells/mL. Four media, after calculations, produced fewer cells ...

Nuclear Strikes

... Soviet Union). Other nations were involved, and 2 wars were fought over it (Korea and Vietnam) and a nuclear war was almost waged (Cuban Missile Crisis). Now with the breakup of the Soviet Union into a loose Commonwealth no one is exactly sure who has all the weapons. Certain nations inherited them, Belarus, Kazakhstan, Ukraine, and Russia, while others tried stealing them, Iran, Libya, and North Korea. And since the breakup certain people have been caught stealing the materials needed to make a bomb. These terrorists have never been caught in ...

It can sometimes be difficult to distinguish whether or not someone has been exposed to the other form of , genital . This is because there are very often no symptoms that go along with the virus. This is ...

Chemistry: Acid-Base Titration

... was added gradually to another solution of NaOH concentration until the chemical reaction between the two solutions were completed. The equivalence point was the point at which the acid was completely reacted with or neutralized by the base. The point was signaled by a changing of color of an indicator that had been added to the acid solution. Indicator was substance that had distinctly different colors in acidic and basic media. Phenolphthalein was a common indicator which was colorless in acidic and neutral solutions, but reddis ...

Ozone

... resides approximately between twenty and forty kilometers high in the stratosphere. The ozone layer reactions that both create and destroy ozone has come into a dynamic equilibrium. This dynamic equilibrium is very delicate and resulted during atmospheric formation (Environment Canada, 1996). Ozone, however, is very rare even in the ozone layer. Oxygen makes up approximately twenty percent of air and ozone makes up only 3 x 10-5 percent of air. Furthermore, this minuscule amount of ozone is enough to protect the earth from ...

Are UFOs Real?

... the bible, just when did the phenomenon with UFO's come about? There are certain reasons and possible explanations as to why UFO's became so popular at one particular time.

Another odd fact about UFO's is that if they are suppose to be out there somewhere why did the government stop research on ...

Nuclear Energy

... almost completely to that of the properties of kinetic fission particles, only that the properties of the nuclear energies nucleus are radioactive. These radioactive nucleuses can be contained and used as fuel for the power. Most of this power is fueled by uranium isotopes. These isotopes are highly radioactive. The isotope catches the fast moving neutrons created by the splitting atoms, it repels the slower moving protons and electrons, then gathers the neutrons and pulls them inward. While all these atoms are flying about they smash ...

Origin Of The Solar System

... of the orbits of the regular satellites of Jupiter, Saturn, and Uranus increase in a regular manner. In modern times the slow rotation of the Sun has been explained as resulting from the deceleration of its angular motion through its magnetic interaction with the outflowing solar wind, so that this feature should not have been considered a constraint on theories of the origin of the solar system. The many theories concerning the origin of the solar system that have been advanced during the last three centuries can be classified as e ...

Aids 5

... disease had spread to virtually all populated areas of the world. In the United States alone there are about 65,000 new cases every year.

Later patients included those who used unsterilized intravenous needles to inject drugs; hemophiliacs (persons with a blood-clotting disorder) and others who had received blood transfusions; females whose male sex ...

Types Of Microphones

... microphones. Dynamic mics are very good, but are less sensitive they are used in noisy places. Two problems with the microphone is that when someone talks the "p" and "s" sounds come out. Condenser microphones are becoming more and more intricate. First of all many microphones contain little batteries about the size of a hearing aid. The batteries last a very long time. The television field uses around four kinds of microphones as basic equipment; the hand-held omnidirectional, the tiny lavalier mic, which is used by clipping on clothing ...
