Fitness: Philosophical Problems, Grant Ramsey, Charles H. Pence
Fitness: Philosophical Problems, Grant Ramsey, Charles H. Pence
Faculty Publications
Fitness plays many roles throughout evolutionary theory, from a measure of populations in the wild to a central element in abstract theoretical presentations of natural selection. It has thus been the subject of an extensive philosophical literature, which has primarily centred on the way to understand the relationship between fitness values and reproductive outcomes. If fitness is a probabilistic or statistical quantity, how is it to be defined in general theoretical contexts? How can it be measured? Can a single conceptual model for fitness be offered that applies to all biological cases, or must fitness measures be case-specific? Philosophers have …

Oxygen Consumption During Exercise: The Role Of Venous Occlusion, Tiffany Noel Saltzman
Oxygen Consumption During Exercise: The Role Of Venous Occlusion, Tiffany Noel Saltzman
LSU Master's Theses
Abstract Oxygen consumption during exercise is typically used to advance performance, determine fitness level, and make clinical diagnoses. The rate at which VO2 adjusts to and recovers from (i.e. on- and off- kinetics) a bout of exercise is typically associated with certain metabolic processes such as stores of PCr, ATP, replenishing myoglobin, hemoglobin, and removing metabolic waste. The ability of an individual to utilize these processes can determine the speed at which oxygen consumption rises and falls, and thus is associated with the health of the individual (i.e. faster=fitter; slower=unhealthy). The use of circulatory occlusion training has recently become a …
The Use Of Duddingtonia Flagrans For Gastrointestinal Parasitic Nematode Control In Feces Of Exotic Artiodactylids At Disney's Animal Kingdom®, Jenna Terry
LSU Master's Theses
Gastrointestinal nematodes (GIN) are parasites of major concern for domestic and exotic ruminant species around the world. In the past, zoological facilities used anthelmintics as their primary control method. Challenges in accurate dosing and administration of anthelmintics to exotic hoofstock contributed to the development of resistant nematode populations in zoological settings. The historic dependency on anthelmintics to control GIN populations is no longer an option. Biological alternatives are urgently needed, in both exotic and domestic ruminants, in the war against resistance. One such alternative is the use of the nematophagous fungus, Duddingtonia flagrans. Three independent studies were conducted: A nine …
A Linear Programming Model And Partial Budget Analysis To Optimize Management Strategies Of Western Flower Thrips In Greenhouse Impatiens Production, Xiaohua Yue
LSU Master's Theses
The research problem of this thesis was to compare strategies and costs of protecting impatiens in greenhouse culture from western flower thrips that would provide a plant of acceptable quality to the market and would address the issue of development of resistance to commonly used pesticides by evaluating biopesticides. Partial budgets based on alternative strategies were identified. Six control strategies were identified from a combination of commercial growers, research experts and biopesticide recommendations from product distributors. The research-recommended strategy 6 had the highest total production cost ($197.44), while one of the grower strategies based on conventional pesticides had the lowest …
Assessing The Efficiency Of Alternative Best Management Practices To Reduce Nonpoint Source Pollution In The Broiler Production Region Of Louisiana, Bryan Gottshall
Assessing The Efficiency Of Alternative Best Management Practices To Reduce Nonpoint Source Pollution In The Broiler Production Region Of Louisiana, Bryan Gottshall
LSU Master's Theses
The Louisiana broiler production region is located in North Central and Northwestern Louisiana. The region consists of twelve parishes in Northwestern and North Central Louisiana. The broiler production region is a significant contributor of nonpoint source (NPS) pollution to nearby waterways. This pollution is a consequence of sediment, nitrogen and phosphorus runoff caused by agricultural production. NPS pollution is difficult to mitigate due to uncertainties in its point of origin as well as a host of other factors ranging from rainfall to topographical parameters. Best Management Practices (BMPS) have been shown to be a reliable method for reducing nonpoint source …
Perceptions Of The Motivational Climate And Gender Class Structure In Physical Education, Lauren E. Delgado
Perceptions Of The Motivational Climate And Gender Class Structure In Physical Education, Lauren E. Delgado
LSU Master's Theses
Many children do not engage in the recommended levels of physical activity, and they ten to become even less active during adolescence. Girls are less active then boys, and it is important to explore ways that physical education teachers can foster girls’ motivation to be more physically active. The specific research questions for this study were: (a) How does gender class structure affect girls’ perception of the motivational climate?; and (b) How do girls’ views of the motivation climate in different gender class structures relate to intentions to participate in physical activity outside of physical education? A phenomenological framework guided …

Influence Of "Added" Whey Protein Isolate On Probiotic Properties Of Yogurt Culture Bacteria And Yogurt Characteristics, Luis Alfonso Vargas Lopez
Influence Of "Added" Whey Protein Isolate On Probiotic Properties Of Yogurt Culture Bacteria And Yogurt Characteristics, Luis Alfonso Vargas Lopez
LSU Master's Theses
Consumers are becoming conscious of their diet, increasing protein intake and avoiding carbohydrates and fats. Whey proteins have branch chain amino acids responsible for muscle building. Whey protein isolate (WPI) contains more than 90% protein. The effect of incremental addition of WPI on probiotic characteristics of pure cultures and cultures in yogurt and yogurt characteristics are not known. The hypothesis was that “added” WPI will influence the characteristics of yogurt culture bacteria in pure form and in yogurt. The objectives were: to determine the influence of added WPI on (1) acid and bile tolerance, growth and protease activity of pure …
Proteomics-Based Study Of Host-Fungus Interaction Between Soybean And Phakopsora Pachyrhizi Using Recombinant Inbred Line (Ril) Derived Sister Lines, Mala Ganiger
LSU Master's Theses
Phakopsora pachyrhizi, the causal agent of Asian soybean rust (ASR), has the potential to cause severe yield losses as all United States commercial soybean varieties are susceptible. In this study, 10 soybean recombinant inbred line (RIL) derived sibling lines of two populations (RN06-32-2 and RN06-16-1) were evaluated for differences in response to infection by P. pachyrhizi. These lines, which had previously shown differential responses to Florida soybean rust isolates, were evaluated using Louisiana soybean rust isolates under both detached leaf assay and greenhouse in planta inoculation conditions. Sibling lines showed significant differences in response to P. pachyrhizi infection under both …
Concentration And Detection Of Hepatitis A Virus And Its Indicator From Seawater, Jiemin Cormier
Concentration And Detection Of Hepatitis A Virus And Its Indicator From Seawater, Jiemin Cormier
LSU Doctoral Dissertations
Hepatitis A virus (HAV) infection is the leading worldwide cause of acute viral hepatitis, and its outbreaks often occur from fecal contaminated shellfish. HAV is extremely stable in the environment and can survive 3~10 months in water. In addition, HAV can be bio-concentrated by shellfish by as much as 100 fold from fecal contaminated waters. Bacteriophage MS2 is used widely as a surrogate for HAV, and its presence has been proven to be a reliable indication of the presence of HAV. A rapid detection of viral contamination in water environments can prevent economic loss and can identify the source of …

To better ensure the safety of these products and protect public health, rapid, accurate, and reliable detection methods for Salmonella are needed. Molecular-based methods like loop-mediated isothermal amplification (LAMP), have gained wide applications in Salmonella detection, owning to their rapidity, specificity, and sensitivity. However, there is a paucity of data on the robustness of these assays. And very …
Mathematical And Computer-Based Models For Optimizing Microwave Heating Processes Of Frozen Oysters, Jie Zhang
Mathematical And Computer-Based Models For Optimizing Microwave Heating Processes Of Frozen Oysters, Jie Zhang
LSU Doctoral Dissertations
Consumers with full-time jobs prefer microwavable-frozen-meals for convenience when lack time to cook. Microwaves do not require a medium for heat transfer and provide quick heating even in low thermal conductivity foods, which does not occur in conventional heating. The main problem in utilizing microwave-heating for cooking is the non-uniform temperature distribution in foods which may result in insufficient lethality of microorganisms in some part. This non-uniformity can be due to a number of factors including composition and geometry of food. The objectives of this study were to develop a mathematical-model based on Maxwell¡¯s equations for predicting the temperature distribution …
