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.

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.

Designer Babies
[ send me this paper ]
An 8 page research paper that investigates the possible ethical ramifications of biotechnological advancements that predict the advent of "designer babies," that is, children whose genes have been manipulated for certain traits or bodily characteristics. Based on futuristic predictions, the writer argues against the morality of such technology. Bibliography lists 6 sources.

Designing a Research Framework
[ send me this paper ]
This 4 page paper helps the student design research to test an hypothesis. The framework shown is the framing of the null hypothesis (H0) and the alternative hypothesis (H1), the decision on what level of confidence to choose, looking at which statistics to test and deciding on which tests are most suitable. The example used is testing to see if genetically modified food and non modified food are the same. The bibliography cites 4 sources.
