Fluorescence Study Of Dyes
.... is enhanced trough energy transfer. We will distinguish between collisional energy transfer and dipole-dipole transfer. From here we will try to determine the quenching constant and the distance at which decay and energy transfer are equally probable, as well as prove that Stern-Volmer's law and Förster's theory are obeyed.

We made up stock solutions for both salts and diluted them down to use in the UV/vis spectrometer.

Forensic Psychology
.... Some examples of the services for the family court cases are: child custody evaluations, visitation risk assessment, evaluations to access termination of parental rights, adoption readiness evaluations ("Forensic Psychological Evaluations").
Forensic counseling for anger management usually occurs in child abuse, domestic violence or assault cases. When a parent has been found to lose control with a child, the parent will be required to receive anger control counseling as a condition of contact with .....

Forensic Science
.... to visit the crime scene, conduct an autopsy (examination
of the body) in cases of death, examine the medical evidence and lab reports,
study the victims history, and put all the information together in a report to be
turned in to the district attorney.
Medical examiners are usually physicians specializing in forensic
pathology, the study of structural and functional changes in the body as a
result of injury. Their training and qualifications most often include a medical
degree and an apprent .....

Forest Management
.... should be
made to manage a wide range of forest structures. Maintaining diversity would
be best served by using a broader range of management tools. Those would
include harvesting on federal land - not simply thinning - and increasing the
commitment to old-growth attributes on private forest land through
techniques such as retaining large trees and snags. As long as federal lands
are substantially committed to providing late successional habitat, private
forest land can be substantially c .....

Forests And Oceans As Carbon Sinks
.... Through the ice sheet, we know that 160 000 years ago, carbon dioxide concentrations were about 180 ppm and have presently exceeded 350 ppm.
5) There are mainly 3 major sources of carbon dioxide presently and historically. They are industrial activity, land use change and cement plants. The carbon dioxide from industrial activity mainly comes from fossil fuel burning and is by far the most abundant of sources. The carbon dioxide from land use change comes mostly from deforestation which occurs mo .....

Formation Of Protocells
.... -- grow and multiply. A trace of these microspheres where found in fossils believed to be 3.4 billion years old. This once again inforces the theory of amino acids being the first building blocks on earth.
These amino acids, with the help of fatty acids, were able to form protocells.
These cell-like organisms were able to survive and reproduce in a very limited environment because of their simplicity. Over time, some of these protocells came together and shared their specialization in a symbio .....

The hazy smog that hangs over us in the summer is actually ground level ozone; the most harmful pollutant of our air (Information 59). Pollutants of the air we breathe are very dangerous and cause many problems especially to people with breathing disorders. For instance, the E.P.A. estimates that emissions of .....

You might be able to shop around for an airplane ticket and might decide to buy one over the internet, yet the minute you type in your credit card number you attract people in finding that number and using it without your consent. You might be amazed at how easy and helpful sending e-mails is, yet it is also easy for someone to send you unsolicited information, which you might not be interested in and in some instances you might even have objections to it.

Frog Disection
.... enzymes but still manages to break down fat into tiny droplets that are ready for faster chemical breakdown. The frog’s stomach is not as complex as a herbivore’s because they have to break down cellulose, which takes a longer time. (Giffard R. & Nat, M 1986)
This concludes my study on the digestion system of the frog.
FROG'S CIRCULATORY SYSTEM
A frog has a closed circulatory system just like humans. This means blood is always enclosed in blood vessels as it circulates the orga .....

From Legend To Science The Health Benefits Of Tea
.... that it was originally consumed for its therapeutic effects. Zhang Binglun says that ¡§much was written in ancient Chinese books¡¨ about tea, and in particular, about its health benefits:
Drinking genuine tea aids in quenching thirst and in digestion, checks phlegm, wards off sleepiness, stimulates renal activity, improves eyesight and mental prowess, dispels boredom and dissolves greasy food. One cannot do without tea for a single day. (Binglun 334)
Zhang Binglun refers to modern studies that that l .....

From Water To Land
.... earliest tetrapod known is Acanthostega. It is also considered the most primitive tetrapod. It is very close to its fish ancestry, but still anatomically far from its terrestrial relatives. These creatures still lived in water, but they had a lot of the terrestrial tetrapod anatomical characteristics.
Introduction:
Before tetrapods existed, all vertebrates were confined to living in aquatic habitats. The only animals that lived on land were arthropods. Through natural adaptations, the fish developed i .....

.... been blocked. How has this affected your digestive process and what two hormones might be able to alleviate one of the affects.
Secretion inhibits stomach movement, emptying, slows secretion of gastric juices and causes bicarbonate to be dumped in from the pancreas and liver to the small intestine. This neutralizes the acid that is coming in. Since this process does not occur there is an increase of emptying of chyme into the small intestine. The small intestine fills and gastric juices keep flowi .....

Fusion 2
.... Stars, including the Sun, consist of plasma that generates energy by fusion reactions. In these “natural fusion reactors” the reacting, or burning, plasma is confirmed by its own gravity. It is not possible to assemble on Earth a plasma sufficiently massive to be gravitationally confined. The hydrogen bomb is an example of fusion reactions produced in an uncontrolled, unconfined manner in which the energy density is so high that the energy release is explosive. By contrast, th .....

As technology becomes more advanced, this will change, and soon people will not think much of having full access the Internet from a tiny box that they can carry anywhere, just as a person with a Walkman is nothing remarkable. One of the great things about wireless communication is the freedom to be anywhere. The natural extension of the Internet is to allow the elimination of the wires and place the Internet into the car, in public, and the "Netman" on .....

Future Psychology

Our ancient habit is to stumble backwards into the future. We feel that we as individuals make little difference, as if history and the future just happen at us. Obscure plans, which have guided people forward in the past, have now rendered themselves useless. There are no known maps to show pathways into the future.
We’ll need to consider back to our hearts, common sense and basic human capabilities. We’ll need to consider the deep issues at stake and .....
