Delayed Phytotoxicity Syndrome In Louisiana Rice Caused By The Use Of Thiobencarb Herbicide, Chiliang Chen Jan 2002

Delayed Phytotoxicity Syndrome In Louisiana Rice Caused By The Use Of Thiobencarb Herbicide, Chiliang Chen

LSU Doctoral Dissertations

Thiobencarb (TB), widely used for the control of broadleaf weeds, grasses, and sedges in rice fields, is considered safe for rice plants when used at recommended rates. TB's reductive dechlorination product, dechlorinated thiobencarb (DTB), is highly toxic to rice. TB is naturally transformed into DTB in field soils in certain areas in Japan and the United States. The resultant syndrome is called delayed phytotoxicity syndrome (DPS). This research was conducted to characterize DPS in Louisiana, to compare the toxicity of TB and DTB to rice, to determine uptake and retention rates of TB and DTB by rice, to confirm that …

Building Community: An Environmental Approach To Crime Prevention, Gustavo A. Barreto Jan 2002

Building Community: An Environmental Approach To Crime Prevention, Gustavo A. Barreto

LSU Master's Theses

Crime cannot be understood as a single-solution problem. Participation of the community is important to complement and make more efficient any program of crime control by police authorities or any other law enforcement agency. This thesis is intended to create consciousness among designers of the urban environment of their social role. Cities must include places to promote community interaction and formation of social bonds. As social bonds among residents increase, and bonds with the place begin building a sense of territoriality in the community, the residents become active defenders of the place against crime. A theory summary presents different and …

It Came From Outer Space: The Virus, Cultural Anxiety, And Speculative Fiction, Anne-Marie Thomas Jan 2002

It Came From Outer Space: The Virus, Cultural Anxiety, And Speculative Fiction, Anne-Marie Thomas

LSU Doctoral Dissertations

This study seeks to explore and interrogate the “viral reality” of the 1990s, in which the virus, heavily indebted to representations of AIDS for its metaphorical power, emerged as a prominent agent in science and popular culture. What becomes apparent in both fictional and non-fictional texts of this era, however, is that the designation of “virus” transcends specific and material viral phenomena, making the virus itself a touchstone for modern preoccupations with self and other. As constituted by the human body’s interaction with pathogenic agents, the binary of self and other may be deconstructed by an interrogation of the virus …

Denitrification Potential Of Sediment From A Future Mississippi River Diversion Site In Louisiana, Roy Ryuta Iwai Jan 2002

Denitrification Potential Of Sediment From A Future Mississippi River Diversion Site In Louisiana, Roy Ryuta Iwai

LSU Master's Theses

Denitrification potential was determined in surface sediment from Lake Cataouatche, the receiving basin for a future Mississippi River diversion located in the northern portion of the Barataria Basin estuary. Nitrate removal and denitrification was measured in the laboratory using static sediment microcosms flooded with lake water. Dissolved potassium nitrate (KNO3) was added to the microcosms to achieve: 1) an initial nitrate concentration similar to the mean Mississippi River concentration (~1.4 mg NO3-N l-1), and, 2) a high initial nitrate concentration to elicit a denitrification potential (~50 mg NO3-N l-1). Denitrification …

Intracytoplasmic Sperm Injection (Icsi) In Fishes, German Antonio Poleo Jan 2002

Intracytoplasmic Sperm Injection (Icsi) In Fishes, German Antonio Poleo

LSU Doctoral Dissertations

Sperm from zebrafish, Danio rerio, and Nile tilapia, Oreochromis niloticus, were microinjected directly into egg cytoplasm to evaluate the potential for developing a novel method of fertilization. In zebrafish, the sperm of two lines (wild-type and gold, long-fin) were injected with or without activation into activated and non-activated eggs. No significant difference (P = 0.997) in fertilization by intracytoplasmic sperm injection (ICSI) was observed between the two lines or when the sperm were activated or not (P = 0.057). There was significance difference in fertilization between activated and non-activated eggs (P = 0.010). The highest fertilization rate was achieved by …

The Effects Of Phytase In Nutritionally Adequate Diets, Diets Deficient In Calcium And Phosphorus, And The Interactive Effects Of Phytase And Eimeria Acervulina Infection In Broiler Chicks, Brandy Centrell Watson Jan 2002

The Effects Of Phytase In Nutritionally Adequate Diets, Diets Deficient In Calcium And Phosphorus, And The Interactive Effects Of Phytase And Eimeria Acervulina Infection In Broiler Chicks, Brandy Centrell Watson

LSU Master's Theses

Six experiments were conducted to determine the interactive effects of Eimeria acervulina (E. acervulina) infection and phytase, and the effects of phytase in nutritionally adequate diets and in diets deficient in Ca and available P (aP). Corn-soybean meal (C-SBM) diets were used. In Exp 1, treatments were: 1) C-SBM, 1.0% Ca and 0.45% aP; 2) C-SBM, 0.80% Ca and 0.25% aP; 3) Diet 1 + 600 FTU phytase/kg; 4) Diet 2 + 600 FTU phytase/kg; 5 to 8) Diets 1 to 4 but infected with coccidiosis. Weight gain (ADG), feed intake (ADFI), and gain:feed were reduced (P < 0.01) by the coccidial infection and the reduction in Ca and aP. Phytase increased (P < 0.02) ADG and ADFI, regardless of the Ca and aP content of the diet or the presence of coccidiosis. Gain:feed was increased by phytase but only in uninfected chicks (phytase x coccidiosis interaction, P < 0.02). Phytase increased (P < 0.02) bone ash percentage but only in diets deficient in Ca and aP (P < 0.01). Experiments 2 and 3 included only treatments 1 to 4 of Exp 1. The reduction in Ca and aP reduced (P < 0.01) ADG, ADFI, and gain:feed. Phytase addition increased (P < 0.02) ADG and ADFI in diets deficient in Ca and aP and in the nutritionally adequate diets. Experiments 4, 5, and 6 were conducted to determine the effects of phytase on intestinal transit time in broilers. Diets were: 1) C-SBM, 0.9% Ca and 0.35% aP; 2) C-SBM, 0.80% Ca and 0.25% aP + 600 FTU phytase/kg. Transit time on Day 1, but not on Day 7, was faster (P < 0.03) in chicks fed phytase. These data indicate that phytase is effective in the presence of a coccidial infection, but it may not be as effective as in uninfected chicks. Futhermore, phytase increases growth in diets deficient in Ca and aP and in diets formulated to be adequate in all nutrients. This increase in growth may be due to a faster transit time of feed through the digestive tract, resulting in a greater feed intake and gain.

The Role Of Attention In Affect Perception: An Examination Of Mirsky's Four Factor Model Of Attention In Chronic Schizophrenia, Dennis R. Combs Jan 2002

The Role Of Attention In Affect Perception: An Examination Of Mirsky's Four Factor Model Of Attention In Chronic Schizophrenia, Dennis R. Combs

LSU Doctoral Dissertations

Attention and affect perception was examined in a sample of sixty-five persons with chronic schizophrenia. Attentional skills may be related to deficits in affect perception due to a lack of attention to important information contained in the face. Deficits of this sort can dramatically inhibit appropriate social functioning. However, there is a lack of empirical research on this topic. Mirsky's four factor model of attention was used as a broad-based assessment of attentional functioning. The four factors of attention were: 1) Focus-Execute, 2) Encode, 3) Sustain, and 4) Shift. Neuropsychological measures reflective of attentional factor were administered. In this study, …

Pleasure Principles: The Social Construction Of Gambling And Sex Addiction Treatment, M. Kelly James Jan 2002

Pleasure Principles: The Social Construction Of Gambling And Sex Addiction Treatment, M. Kelly James

LSU Doctoral Dissertations

The transformation of behavior into deviance requires many players, individuals, and institutions invested in the social construction process and its outcomes. Although considered private recreational matters by some, gambling and having sex are gaining spotlight in the addiction arena. With the growing availability of casino entertainment, lotteries, OTB venues, prostitution, internet pornography, and 900 numbers, gambling and sex are interpreted, labeled, and treated by addiction recovery specialists. Using ethnographic methods and face-to-face interviews, I explore a southern community’s institutions and practitioners providing services to gambling and sex addicts. I examine the community’s discourse and its methods for defining and controlling …

Treatment Acceptability For The Prevention Of Obesity And Type 2 Diabetes Mellitus: The Effects Of Ethnicity, Weight, And Genetic Predisposition, Jean Marie Thaw Jan 2002

Treatment Acceptability For The Prevention Of Obesity And Type 2 Diabetes Mellitus: The Effects Of Ethnicity, Weight, And Genetic Predisposition, Jean Marie Thaw

LSU Doctoral Dissertations

Childhood obesity and its associated health consequences, such as type 2 diabetes mellitus, have dramatically increased over the past 30 years, with the greatest rise in African-American female children and adolescents. Although current prevention efforts show promising results, recent genetic findings may soon expand treatment strategies to include new medications and gene therapies specifically designed to prevent the development of obesity and type 2 diabetes in children. However, little is known about the acceptability of these interventions. The primary aim of this study was to examine the hypothetical impact of genetic knowledge on treatment acceptability in the prevention of childhood …

Fecal Coliform Decay And Regrowth Kinetics In An Anaerobic Dairy Wastewater Environment, Shufang Liu

LSU Master's Theses

The kinetics of fecal coliforms (FC) decay and regrowth were analyzed under laboratory conditions using filtered dairy wastewater under anaerobic conditions. The mean specific growth rates during the regrowth phase, µr , in the batch study were 1.79, 1.46, and 1.27d-1 for initial organic carbon concentrations of 478, 235 and 127 mg/L COD, respectively. The substrate concentrations had a significant impact on the FC regrowth. A maximum specific growth rate (mmax) of 1.92 d-1, and half-saturated coefficient (ks) of 60.92mg/L were determined from these data. The mean dark FC decay rate coefficients, kd , at 35oC in the batch study …

Perception Of And Reactions To The Presence Of Url's In Print Advertising Of A Non-Technology Brand, Neil Melancon Jan 2002

Perception Of And Reactions To The Presence Of Url's In Print Advertising Of A Non-Technology Brand, Neil Melancon

LSU Master's Theses

This thesis, through an experiment of 108 subjects, studies the relationship between the presence of a Uniform Resource Locator (URL or web address) in newspaper advertisements and perception of the product advertised as well as the likelihood to act on the advertisement. The findings reveal URLs do in fact have an effect on perception, although, as it is suggested in the theoretical framework, it does not necessarily induce the subjects to act on the ad. This study also finds there is a stronger inclination for perception change to take place versus the likelihood for consumers to either seek more information …

Effects Of Structural Marsh Management And Salinity On Sediments, Hydrology, Invertebrates, And Waterbirds In Marsh Ponds During Winter On The Gulf Coast Chenier Plain, Francois Bolduc Jan 2002

Effects Of Structural Marsh Management And Salinity On Sediments, Hydrology, Invertebrates, And Waterbirds In Marsh Ponds During Winter On The Gulf Coast Chenier Plain, Francois Bolduc

LSU Doctoral Dissertations

Compositions of wintering waterbird communities are dependent upon food accessibility (via water depth), biomasses and sizes of their invertebrate prey, which in turn are influenced by the hydrology and sediments of wetland habitats. The hydrology and sediments of marsh ponds on the Gulf Coast Chenier Plain probably are affected by structural marsh management (levees, water control structures and impoundments; SMM) and salinity; therefore, SMM and salinity ultimately may affect wintering waterbird communities. Accordingly, I measured sediment and hydrologic variables, biomasses and sizes of common aquatic invertebrates, and densities of common wintering waterbird species in ponds of impounded freshwater (IF), impounded …

The Relation Between Electrodermal Activity In Sleep, Negative Activity Affect, And Stress In Patients Referred For Nocturnal Polysomnography, Laura Elaine Lajos Jan 2002

The Relation Between Electrodermal Activity In Sleep, Negative Activity Affect, And Stress In Patients Referred For Nocturnal Polysomnography, Laura Elaine Lajos

LSU Doctoral Dissertations

The study of electrodermal activity (EDA) began over a century ago, and the phenomenon has been linked to many aspects of emotion, arousal and attention. A subset of studies has focused on the occurrence of EDA in sleep (EDAS). These investigations have led to definitive conclusions on when EDA is most likely to occur during the sleep cycle, i.e., slow-wave sleep. Studies have also shown that at least moderate stress tends to increase EDAS, but these studies have fallen short methodologically. The aims of the present study were: (a) to investigate the relation of negative affect and stress to EDAS, …

Multidemensional Goals Of Farmers In The Beef Cattle An Dairy Industries, Aydin Basarir Jan 2002

Multidemensional Goals Of Farmers In The Beef Cattle An Dairy Industries, Aydin Basarir

LSU Doctoral Dissertations

Farm firm decision making processes have long been of concern to agricultural economists. The concept of maximizing utility rather than profit is an important concept in multidimensional goal research. The prevalence of low or negative net returns in Louisiana beef and dairy production leads to the hypothesis that goals other than profit maximization compete strongly in producers' decisions. The objective of this study is to determine the hierarchy of goals that motivate beef and dairy producers and evaluate them in a multi-dimensional framework. Seven goals were evaluated in producer decision making: Maintain and Conserve Land, Maximize Profit, Increase Farm Size, …

Pink Paper And The Composition Of Flann O'Brien's At-Swim-Two-Birds, Samuel Kauffman Anderson Jan 2002

Pink Paper And The Composition Of Flann O'Brien's At-Swim-Two-Birds, Samuel Kauffman Anderson

LSU Master's Theses

This thesis is an analysis of the two surviving typescripts of Flann O'Brien's At Swim-Two-Birds. After a brief overview of both typescripts, the thesis focuses on the earlier of the two, especially its use of pink paper, and suggests (based on subject matter, pagination, and stylistic patterns) that the pink pages were written before the typescript's white pages, and therefore that they represent O'Brien's earliest conception of the novel.

Screening And Characterization Of Pathogenic Fungi For Possible Control Of Coptotermes Formosanus, Jianzhong Sun Jan 2002

Screening And Characterization Of Pathogenic Fungi For Possible Control Of Coptotermes Formosanus, Jianzhong Sun

LSU Doctoral Dissertations

Coptotermes formosanus was used as “bait” to isolate pathogenic fungi from soil. Fifteen pathogenic fungal isolates were obtained, all either Metarhizium anisopliae (six isolates) or Beauveria bassiana (nine isolates). There were no differences in numbers of fungal isolates from the three sampling locations. However, significantly more isolates were found in woodlands (eleven) than in pastures (four). Median lethal doses (LD50s) of these fungal species to C. formosanus were interspersed, indicating that fungal isolates rather than species had the greatest effect on virulence. In vitro growth characteristics were significantly correlated with virulence against termites, suggesting that fungal virulence might be predicted …

Interacting Color And Behavior Responses To Multiple Selection Pressures In The Sister Salamander Species Ambystoma Barbouri And Ambystoma Texanum., Tiffany Sacra Garcia Jan 2002

Interacting Color And Behavior Responses To Multiple Selection Pressures In The Sister Salamander Species Ambystoma Barbouri And Ambystoma Texanum., Tiffany Sacra Garcia

University of Kentucky Doctoral Dissertations

My research explores the complex strategies animals adapt to cope with multiple selection pressures. I studied the behavioral and color response of two salamander sister species, Ambystoma barbouri and A. texanum, to temperature, predation risk and ultraviolet radiation (UVR, 280-320 nm). Ambystoma barbouri undergo development in streams, while A. texanum larvae inhabit ponds. Thus, A. barbouri are exposed to increased habitat ephemerality, enhanced predation risk, and UVR exposure. I show how A. barbouri have evolved alternate coping mechanisms in response to these environmental factors, relative to A. texanum. In this comparison study, I've quantified the affects of these selection pressures …

The Effects Of Oryzanol On Bone Mineral Density In Ovariectomized, Retired Breeder Rats, Heather Compton Colona

LSU Master's Theses

The accelerated rate of bone loss that occurs after menopause may be reduced by consuming rice bran oil (RBO), which contains natural oryzanol. Three different forms of oryzanol (natural oryzanol, NO; crystalline oryzanol, CO; and solubilized oryzanol, SO) were evaluated in a rat model of postmenopausal women. Retired Sprague-Dawley breeder rats were stratified by weight and assigned randomly to one of five groups for a thirteen week study. Rats were either variectomized (O, n=37) or sham-operated (ShC, n=10) and assigned to control (C) diets (OC, n=10 or ShC, n=10) or one of three forms of oryzanol (NO, n=9; CO, n=9; …

Bacillus Anthracis Spore Concentrations At Various Carcass Sites, Pamala Rose Coker Jan 2002

Bacillus Anthracis Spore Concentrations At Various Carcass Sites, Pamala Rose Coker

LSU Doctoral Dissertations

Bacillus anthracis, the etiological agent of the disease anthrax, is a bacteria of great importance, both in the past and today. Despite this importance, many questions remain regarding defending against its use as a biological weapon, the bacteria's variation in virulence, and its epidemiology in nature. Using Etest strips (AB BIODISK, Solna, Sweden) to measure the MICs, 25 genetically diverse isolates of B. anthracis were tested to determine their susceptibility to seven clinically relevant antimicrobial agents. Using the NCCLS MIC breakpoints for staphylococci, three isolates were found to be resistant to penicillin and negative for beta-lactamase production. From a group …
