The Impact Of The American Presence On Germans And German-American Grass Roots Relations In Germany, 1950-1960., Dewey Arthur Browder
The Impact Of The American Presence On Germans And German-American Grass Roots Relations In Germany, 1950-1960., Dewey Arthur Browder
LSU Historical Dissertations and Theses
This study is primarily concerned with the years 1950-1960, but the period 1945-1949 is also addressed, because many of the policies and institutions introduced to democratize Germany immediately after World War II were carried forward. The official position on both sides during the 1950s was that cooperation was of the essence. In the beginning, the Americans believed that the virtues of democracy could best be cultivated in the German consciousness if the Germans themselves implemented democratic programs under broad, philosophical guidelines, while simultaneously observing Americans and American ideas in practice. This study points out that the Germans accepted the guidelines …
Molecular Cloning And Sequencing Of The Bacillus Stearothermophilus 6-Phosphofructo-1-Kinase Gene And Of A Partial Rabbit Muscle 6-Phosphofructo-1-Kinase Complementary-Dna., Brent Arthur French
Molecular Cloning And Sequencing Of The Bacillus Stearothermophilus 6-Phosphofructo-1-Kinase Gene And Of A Partial Rabbit Muscle 6-Phosphofructo-1-Kinase Complementary-Dna., Brent Arthur French
LSU Historical Dissertations and Theses
A system is presented for determining the relationships between structure and function in the allosteric enzyme 6-phosphofructo-1-kinase (PFK). The ATP-dependent phosphorylation of fructose 6-phosphate to fructose 1,6-bisphosphate catalyzed by PFK is the first reaction unique to the glycolytic pathway. The structure-function relationships in PFK can now be addressed by site-specific mutagenesis. This is a method for directly testing hypotheses concerning the functions of individual amino acids in a protein molecule. The main body of this dissertation is composed of three sections. The first two sections describe the development of a system by which the structure-function relationships in Bacillus stearothermophilus PFK …

In Vitro Regeneration And Protein Changes Associated With Two Cultivars Of Agrostis Palustris Huds. Cultured Under High Sodium-Chloride Conditions., John Casper Hovanesian
LSU Historical Dissertations and Theses
Calli from 'Penneagle' and 'Seaside' creeping bentgrass (Agrostis palustris Huds.) were selected for enhanced ability to proliferate on media supplemented with 514 mM NaCl. Based on dry matter production and vigor, growth of plants regenerated from NaCl-adapted calli of both cultivars in saline hydroponic nutrient medium, was superior to that of plants regenerated from non-adapted calli. At 257 mM NaCl, plants from NaCl-sensitive calli died or were unable to produce measurable dry matter whereas plants from NcCl-adapted calli grew well. Growth of plants from NaCl-adapted calli was inhibited at 340 mM NaCl. At 514 mM NaCl, resistant plants no longer …
The Louisiana Cooperative Extension Service: A Descriptive History Of Its Origin And Development. (Volumes I And Ii)., Edwin Clark Forrest Jr
The Louisiana Cooperative Extension Service: A Descriptive History Of Its Origin And Development. (Volumes I And Ii)., Edwin Clark Forrest Jr
LSU Historical Dissertations and Theses
This dissertation studies the conditions which brought the Louisiana Cooperative Extension Service (LCES) into existence in 1914 and which have sustained it for over 70 years. The U.S. Department of Agriculture estimates that 40 percent of Russia's population consists of farmers and that approximately 70 percent of China's population are farmers. The significance of these figures in relation to productivity is apparent when contrasted with the United States farm population of 2 percent. The current high level of production in American agriculture, sustained by such a small percentage of the population, is not an accident, as Professor Roy V. Scott, …
Management Of Rhizoctonia Aerial Blight Of Soybean And Biology Of Sclerotia Of Rhizoctonia Solani Kuhn (Louisiana)., Gary Fischer Joye
Management Of Rhizoctonia Aerial Blight Of Soybean And Biology Of Sclerotia Of Rhizoctonia Solani Kuhn (Louisiana)., Gary Fischer Joye
LSU Historical Dissertations and Theses
Rhizoctonia Aerial Blight (RAB) has caused severe damage on susceptible soybean cultivars throughout the southern soybean growing areas in Louisiana and the southeastern United States. During the 1983, 1984, and 1985 growing seasons, several greenhouse and field experiments were conducted to determine the influence of cultural practices (row spacings, plant populations, potassium fertilizer rates, and fungicide treatments) on RAB. A row spacing of 25 cm resulted in higher yields than row spacings of 50, 75, or 100 cm, regardless of disease rating. After the crop canopy had reached its maximum density, disease ratings were not significantly different between row spacings …
Feeding And Microspatial Relationships Of Meiobenthic Harpacticoid Copepods With Microbial Flora., Alan William Decho
Feeding And Microspatial Relationships Of Meiobenthic Harpacticoid Copepods With Microbial Flora., Alan William Decho
LSU Historical Dissertations and Theses
Feeding processes and their relationship to microspatial patterns were examined for several harpacticoid species. Field evidences and laboratory radiolabel experiments suggest that diatoms comprise a major portion of the food resources ingested by harpacticoids. Bacteria and mucus-exopolymer secretions (associated with the bacteria and diatoms) are also ingested, coincidently while ingesting diatoms. Also, significant ontogenetic shifts in food resource utilization occur from naupliar to adult stages. Field grazing rate studies were conducted on an intertidal mudflat over different portions of a tidal cycle using several harpacticoid species (Scottolana canadensis, Microarthridion littorale, Paronychocamptus huntsmani). Highest grazing rates for S. canadensis occurred just …
An Experimental Investigation Into Carbon-Dioxide-Induced Organic Deposition., Josh Chia-Hsine Fu
An Experimental Investigation Into Carbon-Dioxide-Induced Organic Deposition., Josh Chia-Hsine Fu
LSU Historical Dissertations and Theses
Wettability change (or a relative permeability effect) has long been considered a mechanism for enhanced oil recovery. Reports show that adsorption of petroleum heavy ends, mainly asphaltenes and resins, onto a rock surface can alter its wettability. Reports also show that high concentrations of CO$\sb2$ will induce the formation of a solid phase in CO$\sb2$/crude mixtures. However, the propensity of a reservoir system for CO$\sb2$-induced hydrocarbon precipitation and how this deposition affects the rock wettability has not been yet investigated. Once variables such as oil composition, pressure, temperature, brine chemistry, and surface mineralogy are adequately defined it becomes possible to …
Regulation Of Dextransucrase Secretion By Proton Motive Force In Leuconostoc Mesenteroides., David Roland Otts
Regulation Of Dextransucrase Secretion By Proton Motive Force In Leuconostoc Mesenteroides., David Roland Otts
LSU Historical Dissertations and Theses
The relationship between proton motive force and the secretion of the enzyme dextransucrase (E.C. 2.4.1.5) in Leuconostoc mesenteroides was investigated. The transmembrane pH gradient was determined by measurement of the uptake of radiolabeled benzoate or methylamine while the membrane potential was determined by measurement of the uptake of radiolabeled tetraphenylphosphonium bromide. Leuconostoc mesenteroides was able to maintain a constant proton motive force of $-130$ mV when grown in fermenters at constant pH while a value of $-140$ mV was determined from concentrated cell suspensions. The contribution of the membrane potential and transmembrane pH gradient to the proton motive force varied …

Ultrastructural And Molecular Studies Of The Fungus {\It Mucor\/}: The Mitochondrion And The Recombinant-Rna Genome., Geun Eog Ji
LSU Historical Dissertations and Theses
Mitochondria from aerobic hyphae of Mucor racemosus displayed a relatively elongated morphology with well developed cristae and stained in positive contrast. Mitochondria from anaerobic yeast cells were more circular in form, displayed less distinct but well recognizable cristae, and stained in negative contrast. Tween 80, ergosterol or cerulenin did not alter mitochondrial morphology when added to cultures. Mitochondria from cells grown in the presence of chloramphenicol displayed a morphology intermediate between those of yeast and hyphae and stained in negative contrast. Mitochondria were isolated by isopycnic centrifugation in Percoll. A single band in hyphal preparations displayed cyanide-sensitive respiration and was …
Marital Relationships And Conflict Resolution Skills Of Bulimics., Dorothy Jo Van Buren
Marital Relationships And Conflict Resolution Skills Of Bulimics., Dorothy Jo Van Buren
LSU Historical Dissertations and Theses
Bulimia is an eating disorder characterized by episodic binge eating and other related symptomatology. Previous research suggests that bulimics experience interpersonal problems particularly in the areas of conflict resolution and in their satisfaction with their roles within their families and marriages. The present study compared 12 bulimic couples to 14 maritally distressed couples and 15 normal control couples on measures of relationship satisfaction, conflict resolution styles, and beliefs about intimate relationships. In addition, couples' communication styles were analyzed based on their participation in an analogue conflict situation. Results of this study provided support for the contention that bulimics experience dissatisfaction …
Development Of Wash And Cook-Proof Methods For Rice Enrichment., Esmond Winston Joseph
Development Of Wash And Cook-Proof Methods For Rice Enrichment., Esmond Winston Joseph
LSU Historical Dissertations and Theses
Rice grains were simultaneously enriched with vitamin (thiamine, riboflavin, niacin and pyridoxine) mixes and cross-linked under acidic and alkali conditions using acetaldehyde and epichlorohydrin, respectively. Results indicated that acidic cross-linked rices had higher vitamin contents than corresponding alkali cross-linked rices. Acidic rices were also shown to be more successful in allowing the vitamin mixes to penetrate the surface of rice grains and to subsequently interact with and become an integral part of rice starch matrix. These acidic enriched rices had higher individual vitamin values of greater than 100% at the 3 gram level than both the control (untreated rice grains) …

Characteristics Of Rumen Fluid And Particulate Microorganisms And The Effect Of Particulate Microorganisms On In Situ Forage Digestibility., John Adeoye Olubobokun
LSU Historical Dissertations and Theses
The effect of diet and time after feeding on microbial crude protein (CP) and dry matter (DM) associated with undigested rumen particles was investigated using diaminopimelic acid (DAPA) as a microbial marker. In a subsequent experiment, in situ CP and DM digestibilities were corrected for microbial contamination of non-masticated and masticated (M) forages. Particle-associated (PA) microorganisms had a higher (P $<$.01) concentration of organic matter (OM) than fluid microorganisms 2 and 23 h after feeding. Bacterial fraction had a higher (P $<$.01) concentration of CP than protozoal fraction. However, the quantity of OM, CP and DAPA per ml of strained rumen fluid equivalent were higher (P $<$.01) in the protozoal than in respective bacterial fractions. In experiment two, CP and DAPA concentrations (%) and quantity (mg/ml SRFE) of OM, CP and DAPA were constant over time (P $>$.10) in fluid, loosely-associated (LA) and firmly-associated (FA) populations. Mean CP and DAPA concentrations were in the order fluid $>$ LA $>$ FA and fluid = FA $$ fluid (P =.07). Over 50% of the PA population …$.01)>

LSU Historical Dissertations and Theses
Human rectal tumor-18 (HRT-18) cell clones 3F3, 3E3, D2, and 4B3 exhibited differences in cellular morphology in Giemsa-stained cultures and developing monolayers. Differences were evident in growth kinetics and plating efficiency of each clone. The clones produced colonies in soft agar, demonstrating anchorage independence. Cytopathic expression (CPE) including cytoplasmic vacuolization and cell fusion occurred in BCV-L9-infected clones 3F3, D2, and 3E3. Cell fusion was inapparent in clone 4B3. Bovine coronavirus strain L9 (BCV-L9) and 5 wild-type isolates replicated in HRT-18 cells, inducing cell fusion. Strain L9, exclusively, replicated in D2BFS cells, requiring trypsin to induce cell fusion. Strain L9 produced …

The Public Reading Career Of Agnes Moorehead: An Investigation Of Her Theory And Practice., Orville Leon Perkins
LSU Historical Dissertations and Theses
Agnes Moorehead worked as a professional actress for forty-five years. She was employed in all the major entertainment fields of her time--theatre, vaudeville, radio, film, television and the recording industry. A significant reason for this almost constant employment was Moorehead's career as a public reader of literature. The purpose of this study is twofold. First, it seeks to document Moorehead's public reading career with emphasis upon her solo performances of literature and in so doing to provide an investigation of those people and events that most influenced her success as an oral reader. The second purpose is to postulate Moorehead's …

Effects Of Chloride On Paramagnetic Coupling Of Manganese In Calcium Chloride-Washed Photosystem Ii Preparations, Gopinath Mavankal, Douglas C. Mccain, Terry M. Bricker
Faculty Publications
The effect of chloride on paramagnetic coupling of manganese in the oxygen-evolving complex of CaCl2--washed PS II preparations was examined using Q-band ESR. When these PS II preparations were depleted of chloride, a strong 6-line ESR signal characteristic of protein-bound, uncoupled manganese was observed. Incubation at high chloride concentrations caused the disappearance of this signal. By repeated removal and addition of chloride, the signal could be cycled on and off without loss of bound manganese. When in a chloride-depleted state, the ESR-detectable protein-bound manganese could be removed by treatment with EDTA. Subsequent heating of EDTA-treated preparations revealed a second pool …

Studies On The Molecular Cloning Of A Gene For Beta-Glucosidase From A Bacillus Cereus/Cellulomonas Sp. Hybrid Bacterium Derived Through Protoplast Fusion., Eun Soo Han
LSU Historical Dissertations and Theses
A (beta)-glucosidase gene was cloned from a cellulolytic bacterium, which was obtained by hybrid-formation between Bacillus cereus and a Cellulomonas sp. through protoplast fusion, into Escherichia coli plasmid pBR322 using recombinant DNA techniques. E. coli strain transformants of JM83 harboring this cloned plasmid were able to utilize cellobiose as a carbon source. (beta)-glucosidase activity was assayed in these cells by P-nitrophenyl (beta)-D-glucopyranoside (PNPG) hydrolysis. Hybridization of the cloned DNA fragment with DNA from the hybrid organism was performed by Southern transfer (92) and DNA/DNA dot blot procedures. The hybridization data strongly suggested that the DNA cloned into pBR322 was from …
The Effect Of Educational Technology Variables On Elementary Education Student Achievement (Instructional Materials, Educational Media)., Deborah Scruggs Miller
The Effect Of Educational Technology Variables On Elementary Education Student Achievement (Instructional Materials, Educational Media)., Deborah Scruggs Miller
LSU Historical Dissertations and Theses
The purpose of this study was to determine whether educational technology variables differentiate between "effective" and "ineffective" elementary schools. It was hypothesized that "effective schools" use educational media in instruction more frequently than "ineffective schools". It was also expected that "effective schools" use educational media in qualitatively superior ways to "ineffective schools". In addition, it was predicted that "effective schools" would have better prepared teachers in educational media and teachers with more years of teaching experience than "ineffective schools". The sample consisted of fourteen elementary schools located in 12 school districts throughout Louisiana. Each school was determined to be either …

Improvement Of Rice Through Somaculture (Somaclonal Variation, Plant Histology, Cell Culture)., Cao Jun
LSU Historical Dissertations and Theses
Research was conducted to develop methods for improving rice through somaclonal variation using plant tissue culture techniques. Experiments were directed toward developing an efficient culture system by which plants could be efficiently regenerated in rice somaculture. Histological studies of the process of callus formation and plant regeneration were also carried out. Explant sources evaluated for their potential for callus induction and plant regeneration included seedling mesocotyl, root-tips, embryos from mature seeds, nodes, immature panicles, and mature panicles. Immature panicles gave the best callus induction and plant regeneration. It was determined that it was necessary to add 2,4-D to the medium …

Explicit Instruction In Story Structure: Effects On Preschoolers' Listening Comprehension (Story Grammar)., Joanne L. Ratliff
LSU Historical Dissertations and Theses
The purpose of the present study was to examine whether instruction in story structure improved preschoolers' comprehension of stories. Preschool children were pretested on: (a) oral story production, (b) story rule knowledge (structural elements), (c) free recall of a story, and (d) probed recall. Students who were identified as less skilled by these four measures were randomly assigned to one of three groups: instruction, story, or control. The instruction group received two weeks of explicit instruction in story structure based on a story rule format. The story group listened to the same rule format. The story group listened to the …

The thermal death time of Clostridium botulinum type E spores in crawfish tailmeat was determined at temperatures ranging from 80 to 95(DEGREES)C. Crawfish paste containing 10('6) spores per gram was dispensed into 16 x 125 mm test tubes, which were subsequently placed in water baths preset at the test temperatures. Sample tubes were removed from the baths at predetermined time intervals and incubated anaerobically for up to two months. The D value for the spores in crawfish tailmeat was determined from the corrected time of exposure to the heat and survival data using three methods of calculation. D values were …
Circadian Lipogenic Responses To Insulin And Prolactin., Anthony Henry Cincotta
Circadian Lipogenic Responses To Insulin And Prolactin., Anthony Henry Cincotta
LSU Historical Dissertations and Theses
Lipogenic responsiveness to insulin was investigated at different times of day in freshly isolated hepatocytes and in primary cultured hepatocytes of Syrian hamsters, Mesocricetus auratus held on 14 hour daily photoperiods (lights on: 08.00) by following (('14)C)acetate incorporation into total cell lipid. The influence of prolactin on lipogenesis was tested by adding the hormone in vivo and directly to primary cultured hepatocytes. The findings of these studies are unique in that they demonstrate important roles of temporal interaction between prolactin and insulin in regulation of lipogenesis in cultured hepatocytes. They are summarized as follows: (1) A circadian variation of lipogenesis …

The Christian Preacher As Poet: A Method For Exposition Of Narrative Portions Of Scripture Based On Aristotle's "Poetics"., William Sherman Phillips Jr
The Christian Preacher As Poet: A Method For Exposition Of Narrative Portions Of Scripture Based On Aristotle's "Poetics"., William Sherman Phillips Jr
LSU Historical Dissertations and Theses
It is the thesis of this study that Aristotle's Poetics provides the basis for a method of exposition that is "distinctively appropriate" for preaching upon the narrative portions of Scripture. The relationship between Aristotelian poetics and narrative exposition of Scripture is examined in terms of the following two questions: (1) How does Aristotelian poetics meet the expository or interpretive need for narrative exposition of Scripture? (2) How does Aristotelian poetics meet the exhortatory or applicative need for narrative exposition of Scripture? The following arguments are made: (1) Aristotelian poetics provides the basis for a method of narrative exposition that unifies …
