Mtbindingsim: Simulate Protein Binding To Microtubules, Julia T. Philip, Charles H. Pence, Holly V. Goodson
Faculty Publications
Summary: Many protein–protein interactions are more complex than can be accounted for by 1:1 binding models. However, biochemists have few tools available to help them recognize and predict the behaviors of these more complicated systems, making it difficult to design experiments that distinguish between possible binding models. MTBindingSim provides researchers with an environment in which they can rapidly compare different models of binding for a given scenario. It is written specifically with microtubule polymers in mind, but many of its models apply equally well to any polymer or any protein–protein interaction. MTBindingSim can thus both help in training intuition about …
Oyun: A New, Free Program For Iterated Prisoner’S Dilemma Tournaments In The Classroom, Charles H. Pence, Lara Buchak
Oyun: A New, Free Program For Iterated Prisoner’S Dilemma Tournaments In The Classroom, Charles H. Pence, Lara Buchak
Faculty Publications
Evolutionary applications of game theory present one of the most pedagogically accessible varieties of genuine, contemporary theoretical biology. We present here Oyun (oy-oon, http://charlespence.net/oyun), a program designed to run iterated prisoner's dilemma tournaments, competitions between prisoner's dilemma strategies developed by the students themselves. Using this software, students are able to readily design and tweak their own strategies, and to see how they fare both in round-robin tournaments and in “evolutionary” tournaments, where the scores in a given “generation” directly determine contribution to the population in the next generation. Oyun is freely available, runs on Windows, Mac, and Linux computers, …

Economic And Attitudinal Perspectives Of The Recreational For-Hire Fishing Industry In The U.S. Gulf Of Mexico, Michelle Savolainen
LSU Master's Theses
Socioeconomic and policy information is important to fisheries management in order to assess potential social and economic impacts of proposed fishing regulations. Previous surveys which collect this type of data for the recreational for-hire (RFH) fishing industry in the U.S. Gulf of Mexico were conducted in 1987 and 1997. The third Gulf-wide survey was conducted in 2010 to update the socioeconomic and policy data available on the RFH industry. More specifically, the survey collected captain, vessel, and trip characteristics, firm and trip financial data, targeted species, and opinions on policy issues and hurricane impacts. State license information indicated that 3,315 …

A Survey Of Ballistosporic Phylloplane Yeasts In Baton Rouge, Louisiana, Sebastian Albu
LSU Master's Theses
A study documenting basidiomycete yeast biodiversity was conducted in Baton Rouge, Louisiana during 2010 and 2011. Using the spore-fall method, the leaf surfaces of seven ferns were sampled at biweekly intervals. Maximum likelihood phylogenetic analyses of the internal transcribed spacer (ITS) region and the D1/D2 domain of the large subunit (LSU) of nuclear ribosomal DNA were used to identify 463 isolates representing 81 species spanning 12 orders within six classes in Basidiomycota. Nearly 30 of these isolates appear to be species new to science. Data indicate fern leaf developmental stage has an effect on the number of yeasts present. A …

Integrated Management Of The Red Imported Fire Ant In Pastures, William Sullivan Hilbun
LSU Master's Theses
The effects and interactions of chemical, cultural, and biological control of red imported fire ant (RIFA) populations were evaluated in two replicated studies in pastures. The first study was conducted from 2005 through 2007 in Washington parish, Louisiana (WP) where the biological control Psuedacteon tricupsis phorid flies were present and at the LSU AgCenter St. Gabriel Research Station in St. Gabriel, Louisiana (SG) where Psuedacteon tricuspis flies were absent. The second study was conducted from May 2009 to May 2010 at St. Gabriel in the presence of phorid flies. In both studies, RIFA population indices in sites treated with methoprene …
Molecular Approaches To Detect And Control Cercospora Kikuchii In Soybeans, Ashok Kumar Chanda
Molecular Approaches To Detect And Control Cercospora Kikuchii In Soybeans, Ashok Kumar Chanda
LSU Doctoral Dissertations
Cercospora leaf blight (CLB) caused by Cercospora kikuchii, has become a troublesome disease in the southern United States. C. kikuchii produces a non-hostspecific phytotoxin and a pathogenicity factor known as cercosporin during infection of soybean. A quantitative real-time PCR assay was developed for detection and quantification of C. kikuchii. The sensitivity of detection is 1 pg of genomic DNA. The assay detected the presence of C. kikuchii in soybean leaves long before the appearance of disease symptoms. C. kikuchii DNA levels in soybean leaves increased slowly during early soybean development, followed by a quick increase at late reproductive stages. Results …

Three Essays On Modeling Economic And Fiscal Change For Communities Under Disequilibrium Following Natural Disasters, Arun Adhikari
Three Essays On Modeling Economic And Fiscal Change For Communities Under Disequilibrium Following Natural Disasters, Arun Adhikari
LSU Doctoral Dissertations
Regional economists and policy makers are interested in forecasting economic changes that are likely to take place at local and state levels after exogenous shocks to an economy; that is, create disequilibrium conditions in terms of supply and demand. Impacts of such shocks could be observed at the level of employment, unemployment, commuting patterns, assessed property values, property and sales taxes and local level of expenditures in several categories. The objective of the first essay was to model the employment change decompositions of different effects in two major industries using a shift share analysis technique in context of Louisiana parishes …
Consumer And Processor Methods To Control Salmonella And Listeria In Shrimp, Genevieve Anne Edwards
Consumer And Processor Methods To Control Salmonella And Listeria In Shrimp, Genevieve Anne Edwards
LSU Master's Theses
A common method used by consumers to determine if shrimp are thoroughly cooked when boiling, is to wait until the shrimp float to the top of the water and are pink in color. The purpose of this study was to determine whether the current floating and color cooking method is adequate to ensure the elimination of Listeria and Salmonella species. Furthermore, to determine if processing and storage methods reduce the effectiveness of this method. Shrimp samples were submerged into bacterial suspensions for 30 min then allowed to air dry for 1 hr and color parameters were measured using a colorimeter. …

Reduced Protein For Late-Lactation Dairy Cows, Andre De Barros Duarte Pereira
LSU Master's Theses
Excess protein in dairy cattle diets unnecessarily increases the cost of production and may contribute to environmental pollution. The objective of this research was to evaluate the effect of feeding dairy cows with two levels of dietary protein on animal performance and manure characteristics. Two experiments were carried out with 24 lactating dairy cows each. Experiment 1 was corn silage based and had a control TMR (HP1) estimated to contain 16.5% CP with SBM and treatment TMR (LP1; 13.5% CP) using DDGS and rumen protected Lys and Met. Experiment 2 was ryegrass haylage based and had a control TMR (HP2) …
Three Essays On Technology Adoption And The Roles Of Off-Farm Labor, Human Capital, And Risk In Contemporary Us Agriculture, Hiroki Uematsu
Three Essays On Technology Adoption And The Roles Of Off-Farm Labor, Human Capital, And Risk In Contemporary Us Agriculture, Hiroki Uematsu
LSU Doctoral Dissertations
Agriculture can be defined as the domestication and farming of plant and animal species to produce food and fiber products. Our society is fundamentally dependent on agriculture as it is the primary source of nutrients essential to human activities. Historically, the introduction of agriculture and technological development thereafter drastically changed the way human civilization has evolved into what it is today. New technologies allow farmers to produce more outputs with fewer inputs. Saved resources from agricultural production, such as land, labor and time, were used elsewhere to produce other goods and services that enrich the quality of our life. The …
Vitamin D Status, Adiposity, And Athletic Performance Measures In College-Aged Students, Laura Forney
Vitamin D Status, Adiposity, And Athletic Performance Measures In College-Aged Students, Laura Forney
LSU Master's Theses
Research suggests that elevated serum concentrations of 25-hydroxyvitamin D (25OHD) are associated with slowing the development of many age-related chronic diseases. Recent reports also show a positive relationship between 25OHD and muscle synthesis, strength, power and decreased body fat in elderly individuals. However, these findings have not been consistently reported in younger, healthy populations. PURPOSE: To investigate the relationship between 25OHD levels, body composition, measures of aerobic fitness and muscular strength and power in a young, physically active population. METHODS: Thirty-nine active subjects (20 males, 19 females; 23 ± 0.7 years old) reported to the lab six times for testing. …
Three Essays On The Efficiency Of Rural Hospitals In The United States, Iustin Cristian Nedelea
Three Essays On The Efficiency Of Rural Hospitals In The United States, Iustin Cristian Nedelea
LSU Doctoral Dissertations
The Critical Access Hospital (CAH) Program was created in response to the dramatic deterioration of financial conditions and the potential threat of closure of small rural hospitals under the Prospective Payment System (PPS). CAHs receive cost-based reimbursement for services provided to Medicare patients in exchange for accepting a number of restrictions. The PPS, which pays a fixed price per case, provides an incentive for hospitals to reduce costs and increase efficiency. In the first essay, I examine the impact of conversion to CAH status on hospital efficiency. The estimated results show that CAHs are less cost and allocatively efficient than …
