20th Century Knowledge -- Revolution or Evolution?
[ send me this paper ]
This 5 page report discusses technological and intellectual advances that have taken place in the 20th century and whether or not such an expansion of knowledge has been due to great new ideas suddenly appearing on the intellectual horizon or a technological evolution of ideas that has led to such commonplace realities as photocopy machines, personal computers, and jet travel. It is important to understand that the foundations of any enterprise determine the heights to which it can rise and the breadth to which it can expand. This writer takes the viewpoint that the advancement of knowledge over the past century has been evolutionary rather than revolutionary. Bibliography lists 2 sources.

Acid Tolerance in Streptococcus mutans
[ send me this paper ]
A 14 page discussion of the physiological mechanism employed by this species of oral bacteria which allow it to exist in the rapidly fluctuating pH levels of the human mouth. The author details how the cellular membrane of the organism is critical in this process, selectively allowing protons to pass out of the cell and preventing them from passing into the cell. This ability allows S. mutans a selective advantage. Acidogenicity (the ability to generate acid) and acidurance (the ability to function in an acidic environment) are the primary physiological traits of this organism which make it such an important factor in the production of dental caries as well. Bibliography lists 7 sources.
