Performance & Carcass Traits Of Swine Of Four Different Phenotypes & Three Usda Grades, Jon Althaus
Performance & Carcass Traits Of Swine Of Four Different Phenotypes & Three Usda Grades, Jon Althaus
Masters Theses & Specialist Projects
The purpose of this study was to compare the performance and carcass characteristics of swine of four different phenotypes and three USDA grades.
Hogs were placed into phenotypic groups of 24 each and penned by group. These pens were ideal, cutability, light muscled, fat, VS US and US The hops were fed a 16% corn and soybean meal ration fortified with appropriate minerals and vitamins. They were housed in a total confinement curtain-sided Kentucky plan building with a partially slatted floor. The hogs were weighed at 6-week intervals throughout the project to monitor average daily gain and pen feed efficiency. …
The Short Term Effects Of Manganese Toxicity On Isocitrate Dehydrogenase In Wheat & Tobacco, Juergen Pfeiffer
The Short Term Effects Of Manganese Toxicity On Isocitrate Dehydrogenase In Wheat & Tobacco, Juergen Pfeiffer
Masters Theses & Specialist Projects
The short term effects of high manganese levels (80 mg/L) on wheat and tobacco isocitrate dehydrogenase (IDH) activity were compared. The change in activity was then compared to the concentrations of manganese in the tissues.
As the time of manganese exposure increased, the fresh weight IDH activities in wheat and tobacco decreased. In contrast both control groups had similar enzyme activities every 6 hr over the 24 hr test period. The decrease in IDH activity of wheat and tobacco plants in experimental groups seemed to be related to an increase of the manganese in the leaf tissue. The slower decrease …
Isolation & Characterization Of Dna Polymerase Alpha And Gamma From Turnips (Brassica Rapa) And Etiolated Soybeans (Glycine Max), Donna Hill
Masters Theses & Specialist Projects
DNA polymerase alpha, the enzyme involved in nuclear DMA replication, and DNA polymerase gamma, the enzyme involved in organellular DNA replication, were isolated and purified from soybean and turnip. The enzymes were characterized following ammonium sulfate precipitation, DEAF-cellulcse, phosphocelluloca, and hydroxylapatite chromatography, and by non-denaturing polyacrylamide gel electrophoresis. Protein banct were electropluted and the enzymes characterized using kinetic studies and sensitivity to divalent cations and inhibitors. Molecular weight and subunit composition studies indicated a molecular weight for the catalytic subunit of DNA polymerase alpha in soybean and turnip to be 46kDa. DNA polymeraqe gamma was composed of a catalytic subunit …

Evaluation Of Fomesafen For Broadleaf Weed Control, In Soybeans (Glycine Max), Ricardo A. Jimenez
Evaluation Of Fomesafen For Broadleaf Weed Control, In Soybeans (Glycine Max), Ricardo A. Jimenez
Masters Theses & Specialist Projects
The lack of effective broadleaf weed control represents one of the major factors having detrimental effects on growth and yield of soybeans. Broadleaf weeds are a serious threat to soybean growers in the southeastern United States. A broad range of herbicides is being used in an effort to control broadleaf weeds in soybeans, and research is still being conducted to find new herbicides that can best work for this purpose. This study involved the use of one these herbicides. It was fomesafen, 5-[2-chloro-4-trifluromethyl) phenoxy]-N-(methyl-sulfonyl)-2-nitrobenzamide, which controls a broad spectrum of broadleaf weeds in soybeans.
The experiment was conducted in the …
Sulfur Accumulation In Xylem Tissue Of Forest Trees From Kentucky & Tennessee & Its Relation To Yearly Growth, Jennifer Sharp
Sulfur Accumulation In Xylem Tissue Of Forest Trees From Kentucky & Tennessee & Its Relation To Yearly Growth, Jennifer Sharp
Masters Theses & Specialist Projects
The levels of sulfur present in xylem tissue of Quercus alba (white oak) show a statistically significant increase from 1970 to 1983. This increase was found in trees from three different sites in Kentucky and Tennessee. The levels of sulfur present in Tsuga canadensis (hemlock) show a statistically significant increase from 1955 to 1970. Sensitivity, growth response to the tree's environment, decreased in oaks from 1933 to 1968 but increased slightly in hemlocks during the same time period. The data tend to support a direct relationship between increasing sulfur levels and a reduction in growth. Physiological and ecological studies of …

Adolescent Smoking Status And Socioeconomic Dependence On The Tobacco Crop In Southeastern Kentucky, Gregory Colwell
Adolescent Smoking Status And Socioeconomic Dependence On The Tobacco Crop In Southeastern Kentucky, Gregory Colwell
Masters Theses & Specialist Projects
The purpose of the study was to quantify the relationship between adolescent smoking and economic dependence on the tobacco crop. A survey of 1322 students from a random sample of all secondary schools in four counties in southeastern Kentucky was performed. The survey gathered information concerning smoking behavior and social variables. Chi-square analysis was performed to assess the relationships between these variables in students from families who worked with tobacco and families who did not.
Chi square analysis of female adolescent smoking behavior revealed a significant association between the instances of adolescent smoking and age, friend smoking status and sibling …

Patterns Of Sulfur Deposition In The Wood Of Pinus Echinatia Mill. From The Cumberland Plateau In Kentucky, Darrell Ray
Patterns Of Sulfur Deposition In The Wood Of Pinus Echinatia Mill. From The Cumberland Plateau In Kentucky, Darrell Ray
Masters Theses & Specialist Projects
Air pollution and acid precipitation have long had an influence on plant and animal life. In this study, the level of sulfur in the stem tissue of Pinus echinata Mill. was measured in trees from various sites along the western edge of the Cumberland Plateau to determine the presence and pattern of sulfur deposition in this species. Overall, a 40.28% increase in sulfur levels was observed from four sites along the plateau with levels increasing from 0.072 mgS/gdwt in the 1962-66 growth increment to 0.101 mg in the 1982-86 increment. According to a computer generated analysis of variance, the differences …
Response Of Three Cultivars Of Bell Pepper (Capsicum Annuum L.) To Mulching & Irrigation, Cesar Gonzalez
Response Of Three Cultivars Of Bell Pepper (Capsicum Annuum L.) To Mulching & Irrigation, Cesar Gonzalez
Masters Theses & Specialist Projects
The effect of black polyethylene mulching and drip irrigation on the yield and quality of three cultivars of bell pepper was studied during the 1987 growing season. This study was conducted on a Pembroke silt loam soil on the Western Kentucky University Farm in Bowling Green, Kentucky. The experimental design was a split-plot arranged in randomized complete blocks in four replications with treatment as the main plot and cultivars as the sub-plot.
'California Wonder,' 'Lady Bell F1 Hybrid: and' Keystone Resistant Giant' cultivars of bell pepper were established in the field during the last week of May. The cultivars …

Sensory Stimuli Involved In Eliciting Agonistic Behavior In The Northern Fence Lizard, Sceloporus Undulatus Hyacinthinus, Laura Taylor
Sensory Stimuli Involved In Eliciting Agonistic Behavior In The Northern Fence Lizard, Sceloporus Undulatus Hyacinthinus, Laura Taylor
Masters Theses & Specialist Projects
Comparisons among sequence analyses of actions in response to various treatments of visual and olfactory cues were carried out in the lizard, Sceloporus undulatus hyacinthinus, to determine the relative roles of these cues in eliciting agonistic behavior. Visual cues were tested using mirrors, models and clear partitions between cages. Chemical cues were tested using the secretion from the cloaca of males. A combination of visual and olfactory cues was tested by streaking a mirror with the substance from the cloaca of a male. The responses to these treatment conditions were videotaped, and the transition frequencies between the most frequently …
