... 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. 2. Results 2.1. Electronic Absorption Spectra We made up stock solutions for both salts and diluted them down to use in the UV/vis spectrometer. Coumarin 1 C = 8 x10-5 mol dm -3 We obtained a spectrum with a maximum at 376.5nm at an absorbance of 1.4573, using Beer-Lambert's law, we deduced the molar decadic absorption coefficients. Sodium fluorescein C = 2.425 x10-5 mol dm -3 Here max was 500.5 nm at an absorbance of 2.0922 Summary of the results obtained. Dye ma ...

... long term outcomes. Any industry that capitalizes on earth's resources figuratively signs a pact with the earth. This pact bonds this industry to the earth and requires that any harvesting of resources is not done so with haste and waste. There is a symbiotic relationship between the two. For the industry to exist there must be a constant supply of the resource. Without a constant supply the industry dies. Now, many people believe that the logging industry's objective is to cut down all the trees that are currently standing. As horrific as this scenario may sound, it is far from the truth. Without trees to cut down there is no industry. The logging industry is not so foolish as t ...

... lower Volga River. By early 1347 it was in Constantinople. It hit Alexandria in the autumn of that year, and by spring 1348, a thousand people a day were dying there. In Cairo, Egypt, the count was seven times that. The disease traveled by ship as readily as by land and it was no sooner in the eastern Mediterranean than it was in the western end as well. Already in 1347, the plague had hit Sicily. By winter the plague had reached mainland Italy. By January of 1348, the plague was in Marseilles, and it reached Paris in the spring of 1348. By September of 1348 the Bubonic Plague had worked its way into Bubonic plague was caused by the bacteria Yersinia Pestis. It is an organism most ...

... Unlike these physical factors, however, fire as a disturbing force is itself influenced by the biota, particularly the plant community. Alteration of the vegetation by any number of factors can influence the nature of a subsequent fire. Fire has similarities to grazing as a force on vegetation because of such feedback effects (Whelan, 1995, 20). Fire History When cavemen learned to make and use fire, they could start to live in civilized ways. With fire, they were able to cook their food so that it was easier to eat and tasted better. By the light of torches, men could more easily find their way at night. They could also improve their wooden tools by hardening the points in fir ...

... Some conditions such as asthma, allergies, autoimmune diseases, fibromyalgia, migraine headaches, osteoarthritis, peptic ulcers, and psoriasis comprise examples of perpetual or chronic inflammation.(3) It is these chronic conditions, hallmarked by pain and fatigue, that eventually lead to loss of function. The treatment that millions of people turn to each year is Non-Steroidal Anti-Inflammatory Drugs (NSAID's). However, long-term therapy has revealed an alarming list of adverse side effects associated with these drugs such as gastrointestinal bleeding, and suppression of inherent anti-inflammatory pathways and tissue repair.(4) In addition, NSAID's have been linked to "leaky gut sy ...

... as living factories for the production of pharmaceuticals and as sources of organs for transplantation into humans in the United States and abroad. Fish are being genetically engineered to grow larger and at a faster rate. According to U.S. News and World Report, many pharmaceutical drugs, including insulin, are already genetically engineered in the laboratory. Many enzymes used in the food industry, including rennet used in cheese production, are also available in genetically engineered form and are in widespread use. Genetic screening is already used to screen for some hereditary conditions. Research is ongoing in the use of gene therapy in the attempt to correct some of these condit ...

... namely the procedures used to create a new organism whose genetic constitution is a replica of another existing individual. Such a feat can be achieved by substituting the nucleus, which contains the genes, from one of the cells making up that individual's body, for the nucleus of a fertilised egg. Since our genes dictate to a large extent what we look like, how we behave and what we can and cannot do, having identical genes, as identical twins do, ensures something more than mere similarity. Novelists and film makers have not been slow to exploit the imagery afforded by cloning. Limitless numbers of identical beings manufactured from existing or previous generations has ob ...

... as 36 wolves. Each pack always has two head leaders, one male and the other female. The pack may hunt and go as far as 130 to 13,000 sq. km.(50 to5,000 sq. miles)—and will defend all that land from intruders. The wolf would have soft fur over it body to cover it like a jacket to keep it warm during the winter. The wolf’s eyes are very keen. It can see and hear very well when hunting for the prey. When you hear a wolf howl it is not to scare you. It can be used for many different reasons such as to show it is happy or to communicate with other wolves. Habitat: Wolves can live in a variety of habitats like the arctic tundra to forest and prairie. But they never live in the deserts or ...

... because (a) one is having problems of functioning as a healthy human being and (b) one remembers being abused as a child that therefore (A) one was abused as a child and (B) the childhood abuse is the cause of one's adulthood problems. There is no evidence that supports the claim that we remember everything that we experience. In fact, there is plenty of evidence to support the claim that it is impossible for us to even attend to all the perceptual elements of any given experience, much less to recall them all. There is no evidence to support the claim that all memories of experiences happened as they remembered to have happened or that they have even happened at all. A ...
