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.

Alfalfa and 'Yellow Rocket' (Barbarea vulgaris)
[ send me this paper ]
This 6 page report discusses the interaction between alfalfa crops and a common weed. The weed chosen for examination is Barbarea vulgaris, most commonly known as 'yellow rocket.' Yellow rocket is usually biennial or perennial with some plants flowering, setting seed and dying after their first growing season; reproducing only by seed but the seeds are notable for their ability to germinate with minimal soil requirements. Yellow rocket and other weeds reduce alfalfa production during establishment by competing with and choking out young alfalfa seedlings, invade established alfalfa fields, and reducing forage quality and yield. Several aspects of intervention and eradication are discussed. Bibliography lists 6 sources.

Altered States of Consciousness and Hypnosis
[ send me this paper ]
This 10 page
report discusses hypnosis and the altered state of consciousness
it produces. While the term “hypnosis” often carries a certain
number of negative connotations that do not truly convey the
beneficial and physiological relation response that is the
legitimate hypnotic response, many people are still hesitant
about the concept in general. The simple fact is that hypnosis is
not a form of mind control and is not the will of one person
being exerted over another. Health professionals, mental health
counselors, even sports performance consultants advocate hypnosis
as a form of stress reduction, pain management and personal
performance enhancement. Bibliography lists 8 sources.
