The Effect Of Phytase On Nutrient Availability In Diets For Swine And Poultry., Sara Leann Johnston Jan 2000

The Effect Of Phytase On Nutrient Availability In Diets For Swine And Poultry., Sara Leann Johnston

LSU Historical Dissertations and Theses

A series of experiments was conducted to determine the effect of increasing phytase coefficient of variation (CV) in chick diets, and to determine the effect of phytase addition on nutrient availability in diets for swine and poultry. The first experiment (EXP) simulated varying mix uniformity of phytase by alternately providing two diets with two different concentrations of microbial phytase (FTU). Increasing phytase CV had little effect on growth performance, whereas bone ash and breaking strength and Ca and P retention and excretion decreased only at the most extreme CV. These data suggest that a phytase CV of between 34 and …

Extended Topics In The Integration Of Data Envelopment Analysis And The Analytic Hierarchy Process In Decision Making., Tae-Sung Kim

LSU Historical Dissertations and Theses

The Analytic Hierarchy Process (AHP) is a procedure, which can only consider relative priorities as estimated by decision-makers. A Data Envelopment Analysis (DEA) model is a data-oriented approach for evaluating the relative efficiency of a group of entities referred to as Decision Making Units (DMUs). This research work integrates and combines positive aspects of AHP's estimated qualitative data and DEA's quantitative data. This combination is accomplished by specifying two variants of the DEA methodology for selection of the best DMU. Initially the priority weights of AHP are integrated with the DEA methodology to provide results that are logic based. Next, …

Glucocorticoid Regulation Of The Leptin Receptor Signaling System In The Rat., Abram Madimabe Madiehe Jan 2000

Glucocorticoid Regulation Of The Leptin Receptor Signaling System In The Rat., Abram Madimabe Madiehe

LSU Historical Dissertations and Theses

Obesity, a recognized health problem, is associated with cardiovascular disease, diabetes and hypertension. Removal of adrenal steroids by adrenalectomy (ADX) slows the development of obesity. Leptin decreases food intake through effects initiated by activation of the JAK-STAT pathway. Defects in leptin signaling lead to obesity, which is associated with hyperleptinemia and leptin resistance. In chapter 4, leptin induces phosphoenolpyruvate carboxykinase (PEPCK) mRNA expression and increases glucose production in hepatocytes from lean but not obese Zucker rats. This suggests that hyperleptinemia in obesity causes hyperglycemia. In chapter 5, ADX decreased the levels of PEPCK mRNA, and increased leptin receptor mRNA expression …

Structure, Expression And Promoter Activity Of Ubiquitin Genes From Rice (Oryza Sativa L.)., Jianlin Wang

LSU Historical Dissertations and Theses

Successful transgenic plant production is largely dependent on the use of suitable promoters. In this study, we described isolation of rice ubiquitin genes, and demonstrated the potential utility of the rice ubiquitin promoters in plant transformation systems. Two polyubiquitin genes (RUBQ1 and RUBQ2) and two ubiquitin extension/fusion genes (RUBQ3 and RUBQ4) have been isolated from a rice genomic BAC library. DNA sequence data revealed that both RUBQ1 and RUBQ2 contained an open reading frame encoding a hexameric precursor ubiquitin and an intron immediate upstream of the initiation codon. The two ubiquitin fusion/extension genes RUBQ3 and RUBQ4 contained one repeat of …

Prospective Memory: Contributions Of Age, Individual Differences, And Metamemory., Celinda M. Reese Jan 2000

Prospective Memory: Contributions Of Age, Individual Differences, And Metamemory., Celinda M. Reese

LSU Historical Dissertations and Theses

The influence of age, ability, monitoring, and metamemory on event-based prospective memory was examined using an adapted version of G. O. Einstein and M. A. McDaniel's (1990) task. Two samples of younger and older adults who differed in educational attainment and verbal ability were compared. Contrary to previous research (Cherry & LeCompte, 1999), the age/ability groups did not differ on prospective memory performance. On-line monitoring ratings were not related to prospective memory but posttest monitoring ratings were. Age differences in reports of task-irrelevant thoughts emerged from the on-line monitoring data. Although age and ability group differences on self-reports of memory …

Effects Of Reading Styles On African-American Preschoolers Of Disadvantage., Elizabeth Nowlin Witt Jan 2000

Effects Of Reading Styles On African-American Preschoolers Of Disadvantage., Elizabeth Nowlin Witt

LSU Historical Dissertations and Theses

This study investigated the effects of two styles of storybook reading within the storybook reading event (SBRE) upon African-American preschoolers of disadvantage (AAP-D). One style, performance-oriented, was thought to be closer to cultural frameworks familiar for this population. This style was contrasted with the interactive style familiar to children of middle-class. Each style was utilized with two groups of five children (ten children per condition) across three storybooks, which were each read six times. Pre- and posttesting were used to determine changes in language (semantic and discourse ability, as measured by retelling), literacy, and world knowledge. A control group of …

Well Integrity Mechanism, Failure, And Testing In Shallow Marine Sediments., Desheng Zhou Jan 2000

Well Integrity Mechanism, Failure, And Testing In Shallow Marine Sediments., Desheng Zhou

LSU Historical Dissertations and Theses

The leak-off test (LOT) is an in-situ method for testing casing shoe integrity in a well. It is used to evaluate the cement and formation integrity relative to the well plan specifications. The results determine whether any remedial cementing or corrective actions are required and are a basis for planning future wells in the area. Typical analysis of LOTs assumes an elastic wellbore and involves identification of linear trends on the recorded plots. However, LOTs recorded in shallow marine sediments (SMS) are inherently nonlinear and their analysis is a problem. Starting from the analyses of shallow soil properties, LOT plots, …

An Information Theoretic Approach To Content Based Image Retrieval., John Morris Zachary Jr Jan 2000

An Information Theoretic Approach To Content Based Image Retrieval., John Morris Zachary Jr

LSU Historical Dissertations and Theses

We propose an information theoretic approach to the representation and comparison of color features in digital images to handle various problems in the area of content-based image retrieval. The interpretation of color histograms as joint probability density functions enables the use of a wide range of concepts from information theory to be considered in the extraction of color features from images and the computation of similarity between pairs of images. The entropy of an image is a measure of the randomness of the color distribution in an image. Rather than replacing color histograms as an image representation, we demonstrate that …

Révision De Quelques Hypothèses Sur Le Creusement Karstique, Jacques Choppy Jan 2000

Révision De Quelques Hypothèses Sur Le Creusement Karstique, Jacques Choppy

International Journal of Speleology

Quite often, as we know better karst phenomena and the evolution of the karst environment, several hypotheses on speleogenesis appeared to be flimsy. Some of these hypotheses, concerning processes playing a part in the creation of karst forms, exceed the limits of their field. Others suggest hydraulic mechanisms, and interventions of geological or geographical factors likely to be questioned. Hypotheses relating to the evolution of karst, as well as the classification of karst types, suffer from the lack of an analytical approach. However, some of these hypotheses still have an important place in the current vision of speleologists and karstologists.

Investigation Of Pattern Classification And Feature Selection Of Gaussian Processes, Vivek Ramaprasad Jan 2000

Investigation Of Pattern Classification And Feature Selection Of Gaussian Processes, Vivek Ramaprasad

Masters Theses

"This thesis focuses on the application of statistical techniques for pattern classification where the patterns are power spectra of the recorded acoustic signals of occluded objects. Different approaches used to classify are : The Bayes linear and piece-wise linear classifiers, the correlation classifier, classification using error spectra and the clustering algorithm. Classifiers were designed and experiments were conducted to investigate the performance. The performance is evaluated in terms of the percentage efficiency by counting the number of vectors identified correctly and the number of vectors which were misclassified. The feature vectors from primitive measurement space is then reduced to lesser …
