Durable Disease Resistance
[ send me this paper ]
Durable disease reduction, an integral
component of modern plant breeding is one solution that many plant
biologists believe will be the deciding factor in whether the world's
population of 2020 will be fed. This 5 page paper argues that the goal
of durable disease resistance is not only possible but also probable
before 2020. Bibliography lists 7 sources.

E Coli
[ send me this paper ]
A 10 page paper discussing the E. coli infection. This is an infection which can
prove to be very dangerous to the health of an individual, and is normally contracted
through tainted meats and dairy products. While the majority of the cases result in
nothing more than digestive problems, there is the chance that an infection could result in
death. A description of the pathogen, and the method of transmission is discussed,
followed by a section discussing the symptoms and effects. There are also sections
covering treatment of the condition and preventive measures that can, and should, be
taken in an effort to reduce the risk of contracting E coli. Bibliography lists 10 sources.

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of the two species, their importance from both agricultural and ecological standpoints, and information (based on the unpublished work of Ronald J. Burkey at Washington State University Agricultural Research Center in Prosser WA) regarding their relative germinations under varying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.
