Crocodiles vs People: A Possible Solution?
[ send me this paper ]
A 13 page paper describing crocodiles and discussing ways in which people can coexist with them. Crocodiles coexisted with the dinosaurs, but they have survived their reptilian relatives by 65 million years. All 23 species were listed as endangered in 1971, but only seven remain so designated. In 2000, it was discovered that crocodile cartilage possesses the same anti-tumor bioactivity as does shark cartilage. Preservation of the crocodile could be important for more than only the ecosystems in which they live. Management in Australia has demonstrated that crocodiles and humans can indeed coexist, without undue strain on either the crocodiles or the humans. Bibliography lists 14 sources.

Current Research in Aspects of Cell Structure
[ send me this paper ]
A 10 page paper discussing current research trained on structure, rather than on processes. There is so much attention focused on biochemical pathways and the interactions of compounds with each other that the basics of structure are often overlooked. As it becomes more important to discover methods of industrial miniaturization and continued enhancement of return on the raw materials of meat and meat product production, we likely can expect greater focus on natural structures and their influence in regulating processes. The paper includes an outline and discussion of research focusing on bacterial flagella, cell walls, cell division and nerve cells. Bibliography lists 11 sources.

Darwin's "Origin of the Species": An Evolutionary Progression of Concepts
[ send me this paper ]
A 10 page discussion of the first eight chapters of Charles Darwin's "Origin of the Species". Presents the thesis that "Origin of the Species" itself is a product of evolutionary progression of thought. The first two-thirds of the book, Chapters 1 through 4, introduce Darwin's most basic evolutionary thoughts while the subsequent chapters 5 through 8 introduce the more complex concepts of Darwin's evolutionary theory. These chapters also show a correlation with the thoughts and work of others of Darwin's time, a correlation which builds rather than diminishes as the book moves from introduction to conclusion. These influences themselves can be contended to be environmental factors in shaping the final layout of "Origin of the Species". Bibliography lists 7 sources.

Darwin's Challenges to Convention
[ send me this paper ]
A 5 page paper discussing evolution, natural selection and social Darwinism. There are many who continue to argue today that Darwin was mistaken, that origin of species could not arise in the manner he described. There are many more, however, absolutely convinced that Darwin found the mechanism by which species arise. The controversy surrounding Darwin's theories continues, further supporting the statement that he challenged accepted scientific theories and changed the way that people viewed science.

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. 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.
