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 …

Control Of Two Perennial Grasses In Southern Turfgrasses, Ronald Eugene Strahan Jan 2002

Control Of Two Perennial Grasses In Southern Turfgrasses, Ronald Eugene Strahan

LSU Doctoral Dissertations

Knotgrass (Paspalum distichum L.) and torpedograss (Panicum repens L.) are perennial grasses that are extremely difficult to remove in established turfgrass. Studies were conducted to determine the potential for controlling these troublesome perennial weeds. Pot studies were conducted for two years to evaluate several herbicides with multiple modes of action for knotgrass control. In graminicides studies, 8 weeks after initial application (WAI) single or split applications of fluazifop or quizalofop provided excellent control (88 to 95%). In contrast, single or split applications of fenoxaprop at 0.21 kg ha-1 and single applications of diclofop at 0.84 kg ha-1 were no better …

Peroxynitrite-Mediated Oxidations: Nitration And Nitrosation, Rachel Bolzan Jan 2002

Peroxynitrite-Mediated Oxidations: Nitration And Nitrosation, Rachel Bolzan

LSU Doctoral Dissertations

Using a direct ultraviolet second-derivative spectroscopy method, three peroxynitrite preparative methods were investigated for the nitrite and nitrate present either as impurities or produced during peroxynitrite decomposition: (I) ozonation of azide, reaction of hydrogen peroxide with (II) isoamyl nitrite and (III) nitrous acid. The oxidation of morpholine by peroxynitrite in the presence and absence of added carbonate gives N-nitromorpholine and N-nitrosomorpholine. Nitration and nitrosation of morpholine are catalyzed by low levels of CO2; however, excess CO2 dramatically reduces the yields of nitrosation but not nitration, and the combined yields of the products are about the same under …

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.

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 …

Prevention Of Eating Disorders In Athletes: An Intervention For Coaches, Brooke L. Whisenhunt Jan 2002

Prevention Of Eating Disorders In Athletes: An Intervention For Coaches, Brooke L. Whisenhunt

LSU Doctoral Dissertations

Research has found that athletes, particularly those involved in "aesthetically-oriented" sports, are at increased risk for engaging in unhealthy weight reduction practices and developing clinical eating disorders. Prevention studies of eating disorders have had some success, but there are very few published studies that address prevention in athletes. This study was designed as an eating disorders prevention program that targeted coaches as change agents. Cheerleading coaches at national or regional conferences attended an intervention workshop or a control workshop. Coaches who attended the intervention workshop received information regarding nutrition, eating disorders, and ways to manage athletes with eating disorders. They …

The Established And Potential Mediating Variables In The Child's Understanding Of Advertising Intent: Towards A Research Agenda, Margaret-Anne Lawlor, Andrea Prothero Jan 2002

The Established And Potential Mediating Variables In The Child's Understanding Of Advertising Intent: Towards A Research Agenda, Margaret-Anne Lawlor, Andrea Prothero

Articles

This paper aims to explore in detail the issue of advertising intent, with particular reference to the child. The literature review examines the importance of age, and cognitive and social development in this field, and considers whether or not children can distinguish between television programming and advertising. What the literature review illustrates is that research studies thus far have conflicting viewpoints on these areas. Within the research to date, there are also a number of important issues which do not seem to be addressed. Most notably, there is little research which considers the impact of advertising upon children, from the …
