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.

Effect of Environmental Conditions on the Germination of Erigeron Species
[ send me this paper ]
A 15 page scientific report regarding the germination rates of two species of fleabanes, Oregon fleabane (Erigeron speciosus) and Piper's Daisy (Erigeron piperianus). Provides information regarding the distribution and ecologies of the two species, their importance from both agricultural and ecological standpoints, and information (based on the unpublished work of Ronald J. Burkey at Washington State University Agricultural Research Center in Prosser WA) regarding their relative germinations under varying planting depths, soil types, cold treatment verses no cold treatment, and light exposure verses germination in the dark. Bibliography lists 8 sources.

Effects of Volatile Anesthetics on G Proteins
[ send me this paper ]
This 12 page
report discusses the effects of volatile (inhalation) anesthetics
on G-proteins. G proteins are a key to the chemical “switches”
that get take place in order to communicate messages in the body.
As the receptors react, they change shape which then allows for
the G protein to also change. It releases the a GDP molecule and
grabs onto a related molecule called GTP. Having attached the
GTP to itself, it then acts on membrane processes such as enzymes
and ion channels. That process then results in a new “messenger”
molecule -- cyclic AMP. An 'enzymatic cascade' then takes place
because the AMP causes a protein reaction. A literature review is
included that outlines a number of the projects regarding the
subject that have been undertaken in the past decade.
Bibliography lists 10 sources.

El Niño's Effects on Agriculture
[ send me this paper ]
A 5 page paper discussing the change of global weather patterns common with the cyclical El Niño originating in the Pacific Ocean. It has been said
that the farmer is the finest example of compulsive gambler in existence. That El Niño events will continue to occur is a given, but prediction and management of them can minimize their negative effects while allowing some producers to take advantage of temporary conditions. Bibliography lists 5 sources.

Energy Transfer in Cells
[ send me this paper ]
This 5 page paper considers energy transfer in cells. The writer looks at the process, defining what is meant by energy and how it can be seen as a two way function of energy transformation. The writer includes consideration of the Laws of Thermodynamics, the role of Adenosine triphosphate (ATP) and metabolic pathways. The bibliography cites 3 sources.

Entamoeba histolytica: Description, History, and Etiology of an Organism Associated with Infectious Diarrhea and Dysentery
[ send me this paper ]
A 5 page overview of this single-celled eukaryote, a common parasite among all classes of vertebrates, several invertebrates, and quite possibly a variety of unicellular organisms. This paper provides a morphological description of the organism, an overview of its life history, and a review of its impacts to humans and the treatment methodologies which are employed. Bibliography lists 6 sources.

Enzymes and the Krebs Cycle
[ send me this paper ]
A 5 page paper discussing enzymes at their most basic
level. Comprised of amino acids, enzymes are the catalysts of myriad biochemical reactions. In keeping with the true nature of catalysts, they accelerate and enable reactions without being materially affected themselves. The second section of the paper presents a diagram of the Krebs or citric acid cycle. Taking place in the mitochondria of the cell, the citric acid cycle is the last in a series of steps that convert 'food' into 'energy.' Bibliography lists 5 sources.

Epidermal Stem Cell and their Role in Wound Healing
[ send me this paper ]
This 6 page paper considers how epidermal stems cells may play a role in healing wounds. The paper discusses the healing process and looks at recent research which indicates the importance of dermal sheath cells in speeding and increasing the quality of wound healing. The bibliography cites 19 sources.
