LSU Doctoral Dissertations
Vibrio parahaemolyticus is a marine bacterium which is the leading cause of bacterial gastroenteritis due to consumption of raw or undercooked bivalve molluscan shellfish in United States and is considered an important seafood-borne pathogen throughout the world. The conventional methods for enumerating this bacteria from seafood is laborious and time consuming, hence the objective of our study was to develop antibody based method which would be sensitive, user-friendly and less time consuming to detect and enumerate Vibrio parahaemolyticus from oysters. In order to condense time and material two rapid and specific antibody based test methods were developed. In the first …
Effect Of Rotational Or Continuous Stocking Method Of Winter Pasture On Beef Heifer Performance, David G. Skeans
Effect Of Rotational Or Continuous Stocking Method Of Winter Pasture On Beef Heifer Performance, David G. Skeans
LSU Master's Theses
Considerable research has been conducted comparing the effect of continuous and some form of rotational stocking method on animal and forage performance, but most research utilizes put-and-take stocking rates. The purpose of this research was to determine the effect of 12-paddock rotational stocking method (ROT) or continuous stocking method (CONT) of winter wheat (Triticum aestivum) and annual ryegrass (Lolium multiflorum) pastures on beef heifer and forage performance while maintaining a continuous stocking rate of 3.7 heifers/ha. Two experiments were conducted and analyzed separately due to confounding year and location. Heifer ADG and WG/ha tended to be increased by ROT compared …
A Divided-Attention Timed Stepping Accuracy Task As A Procedural Learning Intervention Improves Balance And Functional Performance In Healthy Older Adults, Susan Joy Leach
LSU Doctoral Dissertations
For both healthy individuals and individuals at high risk of falling, certain environments, such as a dual-task situation, require more resources than others to prevent a loss of balance. Stepping assessment tasks can be used to predict falls, and it has been suggested that impaired voluntary stepping may be a contributing factor to falls (Lord & Fitzpatrick, 2001). In this research, a stepping task was used not as an assessment, but as a therapeutic intervention. The purpose of this research was to determine how training with a task that provides a procedural learning environment can affect balance and functional outcomes. …
Isoflavone Distribution In Soy Seed And Antioxidant Activity Of Defatted Soy Flour Extract, Xiaohua Yue
Isoflavone Distribution In Soy Seed And Antioxidant Activity Of Defatted Soy Flour Extract, Xiaohua Yue
LSU Doctoral Dissertations
Soy isoflavones distribution in soy cotelydon, coat and germ were determined. The ƒÀ-Glucoside form of isoflavones was the major class of isoflavones in all three soy parts. Soy germ was the richest source of the isoflavones among the three soybean parts. Distribution of the isoflavones in soy cotyledon was different from that in soy coat or germ. As defatted soy flour is a main byproduct in the soy oil refining process, utilizing the low value byproduct as a valuable food antioxidant was investigated in this study. The level of isoflavones in the defatted soy flour extract was 55 mg/g, which …
Essays On Environmental Issues Associated With The Diary Production Region In Louisiana, Larry Michael Hall
Essays On Environmental Issues Associated With The Diary Production Region In Louisiana, Larry Michael Hall
LSU Doctoral Dissertations
The Louisiana dairy production region (LDPR) is located in southeast Louisiana and includes five parishes (Tangipahoa, Washington, Livingston, St. Helena, and St. Tammany). It is home to approximately 90% of the state’s dairy industry and is a major contributor to nonpoint source pollution (NPS) in the area’s watershed through nitrogen, phosphorus, and sediment effluents. While point source (PS) effluents are easily identified and subject to federal and state regulations, NPS mitigation efforts must address uncertainties such as location of the NPS as well as stochastic parameters such as rainfall and its effect on nutrient and sediment flow. This dissertation presents …

Comparisons Of Physicochemical Properties Of Watermelon Juice Treated With Pulsed Electric Fields And Thermal Pasteurization, Lauren Nicole Cook
LSU Master's Theses
Pulsed electric field (PEF) treatment is a non-thermal and alternative pasteurization treatment for fruit juices. PEF applies short pulses of electricity to a liquid food sample which inactivates microorganisms and enzymes. Thermal pasteurization is commonly used to pasteurize juice in the fruit juice industry but the process tends to deteriorate color, nutrients, and overall juice appearance. The overall goal of this study was to determine the effects of PEF treatment (30 kv/cm for 57 ìs in bipolar 2 ìs pulses at 22°C) on color, lycopene content, vitamin C content, pH, °Brix, and microbial count when compared with the effects of …
Survivorship, Tunneling And Feeding Behaviors Of Formosan Subterranean Termite (Isoptera: Rhinotermitidae) In Response To Trans-Caryophyllene, Qiaoling Qi
LSU Master's Theses
The Formosan subterranean termite, Coptotermes formosanus Shiraki, an invasive species from southern China, is one of the most destructive wood pests in the United States. Presently, termites are managed through chemical control. However, some synthetic chemicals cause serious environmental problems due to their persistence and toxicity. There is growing interest in using natural compounds with low toxicity to mammals to control termites. Trans-caryophyllene is a component of essential oil found in many flowering plants. It is especially abundant in clove oil. It has also been found to be released from the roots of maize damaged by insects. I investigated caryophyllene …
