Double Cysteine Mutations In Staphylococcal Nuclease: The Effect Of Artificially Introduced Disulfide Bonds On Protein Structure And Stability, Anna Terry Jan 2000

Double Cysteine Mutations In Staphylococcal Nuclease: The Effect Of Artificially Introduced Disulfide Bonds On Protein Structure And Stability, Anna Terry

Inquiry: The University of Arkansas Undergraduate Research Journal

Since a protein's function depends on its structure, basic research in protein structure facilitates the solution of many practical problems, such as the synthesis of more effective medicines. With this larger goal in sight, the purpose of this research project is to understand better the chemical principles that underlie protein structure and stability. Disulfide bonds are a potentially stabilizing feature of many proteins. They may form between cysteine residues in close proximity to one another if the orientation is favorable. Often found in proteins produced by organisms that grow at high temperatures, disulfide bonds may anchor side chains together, making …

Cultural Atrocity Expressed In Cultural Art, Marlie Mcgovern Jan 2000

Cultural Atrocity Expressed In Cultural Art, Marlie Mcgovern

Inquiry: The University of Arkansas Undergraduate Research Journal

Some of the most horrific chapters in human history have involved an ethnic dimension, notably the centuries-long obliteration of traditional Nigerian cultures by European colonizers, the attempted destruction of European Jews in the Holocaust, and the World War ll decision to assault the Japanese with atomic bombs. The consequences of the above atrocities are not contained within temporal or cultural barriers, but hold profound and pervasive ramifications within contemporary society in its entirety. More recent conflicts in Africa, Southeast Asia and the Balkans reemphasize the horror and suffering brought about by cultural collisions. One of the most potent reactions to …

An Analysis Of The Theory Of Functions Of One Real Variable, Robert J. Reed Jan 2000

An Analysis Of The Theory Of Functions Of One Real Variable, Robert J. Reed

Inquiry: The University of Arkansas Undergraduate Research Journal

Few undergraduates are aware that the Riemann integral taught in introductory calculus courses has only limited application-essentially this integral can be used only to integrate continuous functions over intervals. The necessity to integrate a broader class of functions over a wider range of sets that arises in many applications motivates the theory of abstract integration and functional analysis. The founder of this theory was the French mathematician Henri Lebesgue, who in 1902 defined the "Lebesgue measure" of subsets of the real line. The purpose of this project is to elucidate the theory of abstract measure spaces and of important spaces …

Pentoxifylline Modulation Of The Cytotoxic T-Cell Differentiation Pathway To Enhance Immunological Memory, Eric Goodspeed Jan 2000

Pentoxifylline Modulation Of The Cytotoxic T-Cell Differentiation Pathway To Enhance Immunological Memory, Eric Goodspeed

Inquiry: The University of Arkansas Undergraduate Research Journal

Immunological memory, acquired either by previous infection or vaccination, affords vertebrates a large margin of survival. Subsequent exposure to a "remembered" pathogen signals memory cells to undergo a rapid, clonal proliferation into armed effector cells. This rapidly mobilized clone mediates the specific clearance of the trespassing pathogen. Typically, this secondary recall response effectively dispatches the particular pathogen prior to any manifest disease pathology. This is the age-old, enjoyed benefit of immunity. Though this appreciation for immunological memory has been in documentation for nearly 3 millennia, our ability to intentionally increase its normal level of formation is only now beginning. The …


Old Myths And New Realities: Uncovering The Implications Of Senator J. William Fulbright's Middle East Peace Plan, Angie Maxwell Jan 2000

Old Myths And New Realities: Uncovering The Implications Of Senator J. William Fulbright's Middle East Peace Plan, Angie Maxwell

Inquiry: The University of Arkansas Undergraduate Research Journal

On August 24, 1970, Senator J. William Fulbright presented the speech "Old Myths and New Realities II: The Middle East" to the United States Senate. The intent of this paper is to uncover the significant implications of Senator Fulbright's delivery of this particular speech at this particular moment in American History. In brief, Fulbright proposed a bilateral agreement between the United States and Israel, whereby Israel would return the conquered Arab lands of the I967 War in exchange for military protection from the United States. The speech, when taken out of context, provides a fairly simple plan to initiate peace …


Journeys: The Interpretation Of Modern Myth Through Art, Karen V. Dick Jan 2000

Journeys: The Interpretation Of Modern Myth Through Art, Karen V. Dick

Inquiry: The University of Arkansas Undergraduate Research Journal

"Journeys" primarily investigates the interpretation of one form of expression to another; i.e., the visual interpretation of myth through an in terms of the contemporary individual's psychological voyage. The basis for this study comes from the writings of noted scholar Joseph Campbell and others who place myth in the position of the inward, not the outward journey in the quest for human discovery. As Bill Moyers so eloquently states in The Power of Myth. "myths are the stories of our search through the ages for truth, for meaning, for significance. We all need to tell our story and to understand …

Physical aspects such as range, interference factors, and frequency capabilities and restrictions are assessed. Capacity analysis including round trip times, latency, and throughput are done as well. Issues of authentication and addressing protocols are researched to determine optimal performance and convenience …


Melanocortin-1-Receptor (Mcr-1) Gene Polymorphisms Associated With The Chicken E Locus Alleles, Andrew Ellett Jan 2000

Melanocortin-1-Receptor (Mcr-1) Gene Polymorphisms Associated With The Chicken E Locus Alleles, Andrew Ellett

Inquiry: The University of Arkansas Undergraduate Research Journal

The melanocortin 1-receptor (MCl-R) gene has been associated with E locus phenotypes in chickens. Variant alleles of the E locus are important for accurate down color sexing and also for the inhibition of unwanted tissue pigmentation in broilers. PCR (polymerase chain reaction) based tests for various replacement substitutions found in the published E allele sequences gave unexpected results when tested against known alleles of the E locus. To resolve these issues and gain a better understanding of how replacement substitutions in the MCl-R gene are affecting E locus phenotypes, a number of accessions of the e+, eb, wheaten ( ewh …

The Loop: A Plan For The Future Of Rogers, Rebecca L. Turner

Inquiry: The University of Arkansas Undergraduate Research Journal

Storm water management in urban areas is not only a necessary infrastructure, it is also a valuable resource to provide an aesthetic experience for the public while furthering ecological awareness, recreation, and the cultural fabric. Through the restructuring of current development ordinances and through greater attention to the true needs of the natural and built communities, storm water management becomes the tool to breach the gap between man and nature. Rogers, Arkansas, a city of exciting and alarming growth, maintains traditional planning and environmental practices that have created a center of disequilibrium among the natural and built systems. Local streams …

Studies Of Tryptophans In Membrane- Spanning "Walp" Peptides By Deuterium Nmr Spectroscopy, Nichole Reed Jan 2000

Studies Of Tryptophans In Membrane- Spanning "Walp" Peptides By Deuterium Nmr Spectroscopy, Nichole Reed

Inquiry: The University of Arkansas Undergraduate Research Journal

WALP pep tides of sequence acetyl-Gly-Trp-Trp-(Leu-Ala)-Trp-Trp-Ala-ethanolamine insert into lipid bilayers as membrane-spanning a-helices and modulate the lipid phase behavior as functions of n and the lipid acyl chain length. A key feature of the WALP peptides is the positioning of tryptophan (Trp) indole rings at the membrane/water interface. For the examples WALP19 with n = 6.5 and WALP23 with n = 8.5, we have labeled individual indoles with deuterium and incorporated the labeled peptides in oriented, hydrated bilayers of Dimyristoyl-phosphatidylcholine (DMPC). Deuterium NMR spectra from these samples show sharp resonances when the membrane normal is aligned either parallel (Beta = …

Design, Implementation, And Evaluation Of Virtual Interface Architecture For Power Pc Machines, Ben Mckenzie

Inquiry: The University of Arkansas Undergraduate Research Journal

The Virtual Interface Architecture (VIA) standard is a low-latency protocol that was designed for use in high-performance networks. VIA improves performance by reducing overhead in messaging. This research has two components. The first part of this research project is the development of a new tool for measuring the performance of a VIA implementation and comparing it to the more traditional high-overhead protocols used on the Internet. The development of the tool represents a significant contribution in and of itself, since the tool has been put into the public domain and will likely become useful by Lima users, both for measuring …


Lymphocyte Profiles In Blood And Tumors Of Arkansas Rous Sarcoma Regressor And Progressor Chickens, Brant Ward Jan 2000

Lymphocyte Profiles In Blood And Tumors Of Arkansas Rous Sarcoma Regressor And Progressor Chickens, Brant Ward

Inquiry: The University of Arkansas Undergraduate Research Journal

The Arkansas Rous Sarcoma Regressor (AR) and Progressor (AP) lines of chickens represent an excellent model to study immune responses to tumors. Both lines of chickens initially develop tumors when injected with Rous sarcoma viros (RSV) or with DNA coding for the RSV oncogene v-src (v-src DNA). AR chickens will eventually regress the tumors whereas AP chickens will allow the tumors to progress to a terminal stage. By using both v-src DNA and RSV for tumor induction, we were able to compare the immune response to tumor antigens alone and tumor antigens in combination with viral components, respectively. To study …
