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.
Filename: TEstemce.rtf
Equine Protozoal Myeloencephalitis
[ send me this paper ]
A 5 page overview of Equine Protozoal Myeloencephalitis, its life cycle and its effect on horses. Bibliography lists five sources.
Filename: Eqenceph.wps
Erythrina Speciosa
[ send me this paper ]
A 3 page paper which offers an overview of the plant erythrina speciosa or the coral tree. Bibliography lists 5 sources.
Filename: RAcrlee.rtf
Ethics and Brain Research
[ send me this paper ]
A 7 page research paper & argumentative essay that considers the ramifications of the latest advancements in neuroscience, such as "smart pills." The writer argue that policymakers would be wise to listen to voices warning against the hubris of altering humanity's most distinguished feature, its capacity for reason, the human brain. Bibliography lists 5 sources.

Evidence for Evolution
[ send me this paper ]
A 3 page overview of the theory of evolution. This paper outlines the usefulness of the fossil record, biogeography, comparative anatomy, comparative embryology, and molecular biology as evidence that evolution is a valid concept. Bibliography lists 2 sources.
Filename: PPevolEvdnc.rtf
Evidence of Violent and Non-Violent Cultures in Non-Human Primates
[ send me this paper ]
This 11
page report discusses the fact that when the concept of culture is examined in relationship
to biological anthropology, it offers insight to the ways in which certain behaviors have
developed and whether as they can be thought of as unique to one species or if there is a
biological predetermination to be addressed. Therefore, it is important to look at the
behaviors and cultures of different non-human primates and determine the ways in which
that has influenced the development of humanity. The author of the report uses the
example of violent (chimpanzees) and non-violent (bonobos) social relationships to
consider such questions. Bibliography lists 7 sources.

Evolution & Christian Theology
[ send me this paper ]
A 7 page research paper that examines whether or not Christian theology can accommodate scientific theories about the evolution. The writer, citing the emerging science of chaos and complexity theory, argues that science and theology can be reconciled. Bibliography lists 5 sources.
Filename: khevocom.rtf
Evolution of Bacterial Pathogens
[ send me this paper ]
A 10 page discussion of the mechanisms through which bacterial pathogens evolve. Bacterial pathogens evolve in reference to a number of factors. These are both natural factors and manmade factors. Bacterial evolution in response to antibiotics is one example of this relationship. This evolution occurs both clinically and in areas such as uncontained landfills that have been the recipient of hospital wastes. Once bacteria evolve to reflect a resistance to antibodies they retain that evolutionary feature. Bibliography lists 6 sources.

Evolutionary Mechanisms: The Theory of Heterozygote Superiority Verses The Selfish Gene Theory
[ send me this paper ]
A 9 page discussion of the mechanisms by which evolution occurs. Contrasts the theory of the selfish gene proposed by Richard Dawkins with that of the theory of heterozygote superiority held to by evolutionary biologists such as E. Sober. An overview of each theory is presented. The conclusion is drawn that although certain “selfish” elements do exist (such as is the case with certain highly repetitive DNA sequences) if these elements replicated to the point where it constituted the entire genome of the organism the organism would be sterile and without offspring the too successful gene would be doomed to death. Bibliography lists 10 sources.

Evolutionary Theory and the Existence of Art in the Human Experience
[ send me this paper ]
This 5 page report discusses the reasons behind the existence of art from the point of view of writers and researchers who see it as a fundamental component of the evolutionary processes of humanity. Bibliography lists 5 sources.
Filename: BWevoart.rtf
Evolutionary Wonders: Examples from the Plant and Animal Kingdoms
[ send me this paper ]
A 7 page overview of the marvels of evolution as reflected in six very different representatives of the plant and animal kingdom. This paper notes the lessons mankind might learn from birds, insects, and even the lowly parasitic worms as well as food crops such as corn, medicinal plants such as foxglove, and ornamentals such as the exotic water hyacinth. Bibliography lists 7 sources.
Filename: PPbioFav.rtf
Examination of Journal Articles on Cells
[ send me this paper ]
A 5 page paper which examines and
analyzes two separate articles dealing with cells. The articles, both originating from
Scientific American, are “A ready-made controversy. (SA Perspectives). (cloning and its
controversies)” and “What clones? Widespread scientific doubts greet word of the first
human embryo clones. (Stem Cells).” No additional sources cited.
Filename: RAcells.rtf
Exotic and Invasive Plants
[ send me this paper ]
A 10 page discussion of the attributes of certain plants which give them an advantage over other plants. This paper notes the deleterious impacts on biodiversity which are associated with the arrival of exotics. Bibliography lists 13 sources.
