Cleaner Plastics; Lifecycle and Recycling
[ send me this paper ]
Plastics are associated with poor environmental practices consuming fossil fuels in their production and disposal. This 20 page paper considers the way in plastics production and recycling may be undertaken in a cleaner way. The paper focuses on recycling looking at the lifecycle from the recycling perspective including the creation of plastics using plants that result in biodegradable plastics as well as the ways in which plastics may be recycled.

Defining Osmosis
[ send me this paper ]
This 5 page report discusses and explains the concept of osmosis which is how one element or ingredient of a solution flows through a membrane while other components of a solutuon are shut out and unable to pass through the membrane. In order to determine which membranes allow the flow of which constituents of a solution requires experimentation since not all membranes act the same way. Bibliography lists 8 sources.

Dental Fillings: History, Types and Uses
[ send me this paper ]
An 8 page discussion of the history of dental fillings. Traces the filling from ancient times to present exploring the various types of materials which were used. Explains that the choice of filling is related to performance but also to availability and cost. Notes that the evolutionary path of fillings is tied as well to the evolutionary paths of other dentistry aspects such as drill evolution and the development of molding techniques and materials.

Drug Chemistry: The Effect of Ionization of Absorption and Excretion
[ send me this paper ]
A 4 page overview of the relation of drug ionization, specifically of whether the drug is a weak acid or a weak base, to its absorption into the body and consequent excretion from the body. Notes a differential absorption and excretion, according to physiological pH, as to where the drug is absorbed and when it is excreted. Bibliography lists 3 sources.

Early Photography: The Calotype
[ send me this paper ]
(7pp) The base of a calotype negative, rather than the glass or film to which we have become accustomed, was high quality writing paper. The sheet of paper was carefully selected to have a smooth and uniform texture and, wherever possible, to avoid the watermark. It was offered as the chief alternative to the Daguerreotype and was more popular with amateur photographers, artists, and scientists, who used it widely, since the negative could be corrected with pencil. Bibliography lists 5 sources.

Effects of Volatile Anesthetics on G Proteins
[ send me this paper ]
This 12 page report discusses the effects of volatile (inhalation) anesthetics on G-proteins. G proteins are a key to the chemical “switches” that get take place in order to communicate messages in the body. As the receptors react, they change shape which then allows for the G protein to also change. It releases the a GDP molecule and grabs onto a related molecule called GTP. Having attached the GTP to itself, it then acts on membrane processes such as enzymes and ion channels. That process then results in a new “messenger” molecule -- cyclic AMP. An 'enzymatic cascade' then takes place because the AMP causes a protein reaction. A literature review is included that outlines a number of the projects regarding the subject that have been undertaken in the past decade. Bibliography lists 10 sources.

Energy Transfer in Cells
[ send me this paper ]
This 5 page paper considers energy transfer in cells. The writer looks at the process, defining what is meant by energy and how it can be seen as a two way function of energy transformation. The writer includes consideration of the Laws of Thermodynamics, the role of Adenosine triphosphate (ATP) and metabolic pathways. The bibliography cites 3 sources.

Enzymes and the Krebs Cycle
[ send me this paper ]
A 5 page paper discussing enzymes at their most basic level. Comprised of amino acids, enzymes are the catalysts of myriad biochemical reactions. In keeping with the true nature of catalysts, they accelerate and enable reactions without being materially affected themselves. The second section of the paper presents a diagram of the Krebs or citric acid cycle. Taking place in the mitochondria of the cell, the citric acid cycle is the last in a series of steps that convert 'food' into 'energy.' Bibliography lists 5 sources.
