The Effects Of Avian Influenza Outbreak On U.S. Poultry Prices, Shang-Ho Yang Aug 2006

The Effects Of Avian Influenza Outbreak On U.S. Poultry Prices, Shang-Ho Yang

Masters Theses & Specialist Projects

Even in the absence of proven human-to-human transmission of the disease, the uncertainty surrounding bird flu could devastate regional economic growth and financial markets. Confirmed cases of human infection from several subtypes of avian influenza infection have been reported since 1997. According to WHO (World Health Organization), experts indicate that there is a possible risk of infection to people who have contact with infected birds or surfaces that have been contaminated with secretions or excretions from infected birds during an outbreak of avian influenza among poultry. On May 8, 2006, WHO reported on 207 cases that resulted in 115 people's …

The Effect Of Varying Cadence In Cycle Ergometry On Submaximal Predictions Of Peak Oxygen Uptake, Zachary Callahan Aug 2006

The Effect Of Varying Cadence In Cycle Ergometry On Submaximal Predictions Of Peak Oxygen Uptake, Zachary Callahan

Masters Theses & Specialist Projects

The purpose of this study was to investigate the effect that varying cadence had on the ability of a submaximal cycle ergometry test to accurately predict peak oxygen uptake (VO2) using the standard YMCA protocol workloads. There has been limited scholarship investigating the effect that varying cadence has on trained cyclists and almost none on untrained participants. For this study twelve moderately healthy participants (age: 20.75 ± 1.87, body fat: 15.8 ± 4.91 %) who did not use cycling as part of their workout regime performed a peak VO2 cycle test and three randomized submaximal tests. The three submaximal tests …

Strategies For Reducing Mosquito-Borne Disease Vulnerability In Equine Populations: A Kentucky Case Study, Sara Dalton Aug 2006

Strategies For Reducing Mosquito-Borne Disease Vulnerability In Equine Populations: A Kentucky Case Study, Sara Dalton

Masters Theses & Specialist Projects

This research examined equine management practices that limit or contribute to the spread of West Nile virus and other mosquito-bome disease. I hypothesize that there is a relationship between equine management practices and outbreaks of mosquito-borne disease in horse populations. Improved and appropriate mosquito habitat management may limit the risk of mosquito-borne disease in humans and horses by helping to lower the mosquito populations. The study goals were to recognize equine management practices and mosquito prevention practices that foster outbreaks of mosquito-borne disease. This study used a questionnaire for county level analysis of equine management practices and the relationship to …

Performance Of Pre And Post-Partum Weather Stressed Cows Supplemented With Yeast Culture, Fabian Ortiz May 2006

Performance Of Pre And Post-Partum Weather Stressed Cows Supplemented With Yeast Culture, Fabian Ortiz

Masters Theses & Specialist Projects

Livestock have been fed yeast as a feed supplement for more than 100 years Stone, C. 00). Yeast is a microscopic, single cell fungi of the plant kingdom. Of the 50,000 species of fungi, only 60 different genera of yeast representing about 500 different species exist. A few of these are used commercially in the animal feed industry as active dry yeast or yeast culture (Kreger, van Rij, 1984). Yeast culture consists of live yeast cells, plus the medium on which yeast is grown. Yeast products are commonly fed as pro-biotics, but little is known about their effects. Some studies …

Identifying Exclusion Genes Of Bacteriophage Hk239, Ali Wright Jan 2006

Identifying Exclusion Genes Of Bacteriophage Hk239, Ali Wright

Mahurin Honors College Capstone Experience/Thesis Projects

Temperate bacteriophage can adopt either a lytic or a lysogenic lifestyle. In the lytic lifestyle, the bacteriophage infects a cell, uses the host's cellular machinery to replicate, and lyses the cell to release the phage progeny. In the lysogenic lifestyle the bacteriophage genome is integrated into the bacterial genome to generate a prophage. Most of the genes of the prophage are repressed. However, those genes that are expressed have a wide variety of functions including exclusion, the prevention of phage infection. Lysogens of bacteriophage HK239 have the ability to exclude a wide variety of phage, including (lambda), T4rII, Plvir, P2, …

The Effects Of Heat Stress On High Oil Corn, Summer Goldman Dec 2005

The Effects Of Heat Stress On High Oil Corn, Summer Goldman

Masters Theses & Specialist Projects

High oil corn (HOC) is essentially dent corn that has been selected for high oil content in the scutellum. It is a value-added crop that can potentially offer a premium price for producers. Though southeastern U.S. producers have not had problems achieving sufficient yields, the oil content necessary for premium prices has been elusive. One of the most evident differences between these growers and their northern counterparts is the climate. Temperatures during the reproductive growth and grain fill periods are higher in southern latitudes. A two-part research project was conducted to further investigate the significance of temperature on oil content. …

Effects Of Stretching On Jumping Performance, Carisa Chavez Aug 2005

Effects Of Stretching On Jumping Performance, Carisa Chavez

Masters Theses & Specialist Projects

Stretching has been a part of warm-up for a very long time. Some recent research has shown that stretching could possibly hinder performance and others have shown it enhances performance. The purpose of this study was to examine whether stretching has an effect on vertical jump, and if so, how long the effects last. Twenty Western Kentucky students (10 M and 10 F) performed three trials each. There was a non-stretching group, a pre-stretching group and a between-stretching group; each of the subjects performed all three. The stretching protocol included a static stretching routine of the gluteus maximus, hamstrings, quadriceps, …

Alfred Russel Wallace: Past And Future [Guest Editorial], Charles H. Smith Jan 2005

Alfred Russel Wallace: Past And Future [Guest Editorial], Charles H. Smith

DLPS Faculty Publications

The naturalist Alfred Russel Wallace (1823–1913) has for many years been standing in the shadow of his more famed co-discoverer of the principle of natural selection, Charles Darwin. Despite outward similarities between the two men’s formulation of the principle, Wallace had fit his appreciation of natural selection into views on evolution that were quite different from Darwin’s. A closer examination of what Wallace had in mind suggests a model of process in which natural selection per se acts as the negative feedback mechanism (actually, a ‘statespace’) in the relation between population and environment, and environmental engagement as made possible by …

Phylogenetics Of Rubus Ursinus And R. Macraai (Rosaceae): Evidence Of Hybrid Origin, Brittany Sutherland Jan 2005

Phylogenetics Of Rubus Ursinus And R. Macraai (Rosaceae): Evidence Of Hybrid Origin, Brittany Sutherland

Mahurin Honors College Capstone Experience/Thesis Projects

This study had three goals: elucidating the affinity between Rubus ursin us and Rubus macraei, assessing the hybrid origin of both species, and determining closely related species that may be putative parents. To this end, three chloroplast DNA regions-rp1l6, trnK, trnL-tmF-and two nuclear DNA regions-the ribosomal internal transcribed spacer (ITS) and granule-bound starch synthase (GBSSI)-were sequenced for five R. ursinus individuals, including 6x, 8x, l lx, 12x, and 13x ploidy levels, and R. macraei, which is hexaploid. Sequence data were placed into an existing framework of a Rubus phylogeny. Three phylogenies were created that demonstrate a close association between R. …

Does Genertic Variation Support Geographical And Morphological Patterns? A Phylogentic Interpretation Of Mentha Longifolia (Lamiaceae) Using Molecular Data, Kate L. Hertwick Jan 2005

Does Genertic Variation Support Geographical And Morphological Patterns? A Phylogentic Interpretation Of Mentha Longifolia (Lamiaceae) Using Molecular Data, Kate L. Hertwick

Mahurin Honors College Capstone Experience/Thesis Projects

Traditional taxonomic studies ofMentha longifolia (European horsemint) have utilized geographical and morphological criteria to classify and define the species. This has led to the recognition of 22 different M longifolia subspecies from Europe, the Middle East, central Asia, and southern Africa. Using nucleotide sequences of chloroplast and nuclear DNA regions of 23 accessions of M. longifolia, we assessed levels of genetic divergence to determine if discrete groupings exist. The results ofthis phylogeographic study indicate that there is sufficient variation among samples to warrant splitting of M. longifolia into several different taxa. For example, two subspecies from South Africa share distinct …

Improving The Accuracy Of The Vo2 Max Prediction Obtained From Submaxial Ymca Testing, Lindsay Parson Dec 2004

Improving The Accuracy Of The Vo2 Max Prediction Obtained From Submaxial Ymca Testing, Lindsay Parson

Masters Theses & Specialist Projects

Maximal oxygen uptake (VO2 max) is the best criterion measure for aerobic fitness and the prescription of exercise intensity for programs designed to enhance cardiorespiratory fitness. There are two ways of obtaining VO2 max: maximal tests, which require subjects to exercise to the point of volitional exhaustion and provide the most accurate measure; and submaximal tests, which are less physically strenuous but have lower accuracy. A popular submaximal protocol is the YMCA bike test. Steady state heart rate (HR) is measured at multiple submaximal workloads and extrapolated to the subject's estimated maximal HR (220-age). The VO2 corresponding to the estimated …
