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. Bibliography lists 7 sources.

Denture Cleansers
[ send me this paper ]
5 pages in length. Maintaining one's own teeth is certainly a preferable alternative to having dentures; however, when the time comes to make such a decision, there are a number of considerations to be made beyond merely the fit. If dentures are not properly cleansed on a regular basis, this can lead to the same type of oral decay found in those without dentures. Denture cleansers are manufactured to help continue the process of good oral hygiene by effectively removing the build up of debris from prosthetic dental appliances. Powder, tablet or paste, the choice of material is solely a personal decision based upon past experience and preference. The write discusses various aspects of denture cleansers. Bibliography lists 10 sources.

Desert Surfaces: A Process Based Analysis of Radiation, Heat,
Precipitation, and Storage
[ send me this paper ]
A 7 page overview of the processes which
impact deserts. Summarizes geologic, climatological and biological
processes which interplay to both shape desert environments and which
are shaped by those environments. Outlines the importance of topography, substrate characteristics, precipitation, vegetative cover
(both type and extent), radiation, and cloud cover in particular and concludes that each of these factors is interrelated with the other. Bibliography lists 6 sources.

Destiny or Circumstance?: Are Human Beings in Charge of Their Destiny?
[ send me this paper ]
A 5 page discussion of destiny as it relates to the actional and nonactional theories. Associates the theory of biological determinism with the nonactional theory but observes other areas of research which indicate numerous factors, particularly parental involvement in our childhood, affect the way we live our lives. Concludes that there is some validity to the Actional Theory, the theory that it is us that determine our destiny. What becomes clear, however, is that our destinies are determined not only by factors which are under our control but also be predetermined factors such as our genes. Destiny therefore is predetermined in some instances but entirely under our control in others. Bibliography lists 5 sources.

Durable Disease Resistance
[ send me this paper ]
Durable disease reduction, an integral
component of modern plant breeding is one solution that many plant
biologists believe will be the deciding factor in whether the world's
population of 2020 will be fed. This 5 page paper argues that the goal
of durable disease resistance is not only possible but also probable
before 2020. Bibliography lists 7 sources.

E Coli
[ send me this paper ]
A 10 page paper discussing the E. coli infection. This is an infection which can
prove to be very dangerous to the health of an individual, and is normally contracted
through tainted meats and dairy products. While the majority of the cases result in
nothing more than digestive problems, there is the chance that an infection could result in
death. A description of the pathogen, and the method of transmission is discussed,
followed by a section discussing the symptoms and effects. There are also sections
covering treatment of the condition and preventive measures that can, and should, be
taken in an effort to reduce the risk of contracting E coli. Bibliography lists 10 sources.

Ecosystems: North and South
[ send me this paper ]
(5 pp). As we move into a new century we become
more aware of how hard we were on the planet in
the last one hundred years. This discussion
examines the general criteria of an ecosystem, and
then illustrates what an ecosystem is, by
describing one on a north facing slope, and one on
a south facing slope.
Bibliography lists 3 sources.
