Genotypic Variability And Inheritance Of Iron And Zinc In Sweetpotato, Michael William Courtney Jan 2007

Genotypic Variability And Inheritance Of Iron And Zinc In Sweetpotato, Michael William Courtney

LSU Master's Theses

Sweetpotato [Ipomœa batatas (L.) Lam.] is a major subsistence crop in Sub-Saharan Africa, where iron and zinc deficiency in humans is an important health problem. A sweetpotato cultivar suited for subsistence farming, with high iron and zinc concentration, would be important in alleviating these deficiencies. The main objective of this research was to identify the extent of genetic variability of iron and zinc concentration in sweetpotato germplasm. An important subcomponent of this research was to determine the heritability of iron and zinc in sweetpotato. Protocol development studies were also conducted to aid in determining proper sampling technique. The results of …

Reevaluating Age In Subadult Remains In Response To Secular Changes In Skeletal Growth, Katherine Ann Blackwelder Jan 2007

Reevaluating Age In Subadult Remains In Response To Secular Changes In Skeletal Growth, Katherine Ann Blackwelder

LSU Master's Theses

The goal of forensic anthropology is the analysis and identification of human skeletal remains in a medicolegal context (Byers 2005:1-2). A forensic anthropologist can determine the age of subadult remains by various means, including dentition, centers of ossification, cranial suture closure, and epiphyseal union. Epiphyseal union is when all bones have completed their growth and fused, which happens for all bones by early adulthood. In this way, a forensic anthropologist can analyze the extent of epiphyseal union to determine the age of a deceased individual. This is done by comparing the skeletal remains to age-specific x-ray images of bones featured …

Evaluating The Effect Of Two Commercial Antimicrobial Products On Salmonella Spp. In The Aquatic Habitat Of The Red-Eared Slider Turtle (Trachemys Scripta Elegans), Trevor Theadore Zachariah Jan 2007

Evaluating The Effect Of Two Commercial Antimicrobial Products On Salmonella Spp. In The Aquatic Habitat Of The Red-Eared Slider Turtle (Trachemys Scripta Elegans), Trevor Theadore Zachariah

LSU Master's Theses

Turtle-associated salmonellosis was recognized as a public health concern in the 1960’s, particularly due to an increase in the incidence of disease among children. In response to the public health threat, the United States Food and Drug Administration (FDA) implemented regulations in 1975 restricting the sale of turtle eggs and turtles with a carapace length less than 10.2 cm. Since that time, attempts to eliminate Salmonella from turtles using antibiotics have been unsuccessful and lead to antibiotic resistant strains of Salmonella on turtle farms. Recent work has focused on identifying non-antibiotic products to suppress or eliminate Salmonella and reverse the …

Survival, Habitat Use, And Movements Of Female Mallards Wintering In Southwestern Louisiana, Paul Thomas Link

LSU Master's Theses

Little information is available concerning survival, habitat use, and movements of mallards (Anas platyrhychos) wintering on the Gulf Coast Chenier Plain (GCCP). Quantitative data on these parameters would be useful in making effective management decisions by GCCP waterfowl managers. Accordingly, I radio-marked 135 female mallards during winters 2004-2005 and 2005-2006 in southwestern Louisiana. My estimated survival rate for both winters combined was 0.68 ± 0.06 and did not differ by female age. Hazard ratios indicated that radio-marked females were 21-24 times more likely to die during hunted time periods than during non-hunted time periods. Estimated hunting and non-hunting mortality rates …

Deficits In Social Skills And Feeding Behaviors Associated With Adults Diagnosed With Autistic Disorder Living In An Institutionalized Setting, Cindy Terlonge Graham

LSU Master's Theses

Autistic disorder, a syndrome beginning in infancy and persisting into adulthood, has captured the attention of researchers and clinicians alike. Although this disorder has been studied since the mid-1940s, there is a lack of literature addressing certain adaptive skills in adults with autism. The aim of this study was to examine the differences in social and feeding skills between individuals with and without autistic disorder. Given the importance of acquiring these skills to facilitate proper adjustment and decrease potential health risks, better understanding of these behaviors in persons with autism is warranted. Participants comprised three separate groups: an autism group, …

Mitigating Disaster: Mapping Cognitive Processes In Applying Technology To Crises, John Clinton Borne Jan 2007

Mitigating Disaster: Mapping Cognitive Processes In Applying Technology To Crises, John Clinton Borne

LSU Master's Theses

Extreme events are sometimes defined as unexpected events in which local resources are insufficient to cope with the extent of the damage and require outside resources to address the hazards specific to the event. For that reason, communities immediately adjacent to disaster areas have a unique and important role in the study of measures to mitigate the effects of the resulting hazards to human life and property. This exploratory study looks at the use of information technology in conjunction with disaster mitigation activities in areas adjacent to a large disaster. The experiences, thoughts, and beliefs of individuals involved in mitigation …

Assessment Of The Phosphorus Index For Louisiana, William Lucas Felicien Jan 2007

Assessment Of The Phosphorus Index For Louisiana, William Lucas Felicien

LSU Master's Theses

A phosphorus index is a semi-quantitative to qualitative model for assessing the potential for loss of soil and fertilizer phosphorus (P) to ground and surface water, therefore,eutrophication risk. The concept of a P Index is recent and popular, with most states having developed a P Index that is either a simplification or extension the original 1993 concept. The Louisiana P Index assigns ratings for P loss potential depending on soil properties, topography and land use. These ratings are intended to guide P fertilizer (including animal waste materials) application so as to preserve water quality. This project has examined measured loss …

The Use Of A Chiral Fluorescent Resorcinarene For The Enantiomeric Recognition Of Amino Acids, Gerald I. Richard Jan 2007

The Use Of A Chiral Fluorescent Resorcinarene For The Enantiomeric Recognition Of Amino Acids, Gerald I. Richard

LSU Master's Theses

The spectroscopic properties of a chiral boronic acid based resorcinarene macrocycle employed for chiral analysis were investigated. Specifically, the emission and excitation characteristics of tetraarylboronate resorcinarene macrocycle (TBRM) and its quantum yield were evaluated. The chiral selector TBRM was investigated as a chiral reagent for the enantiomeric discrimination of amino acids using steady-state fluorescence spectroscopy. Chiral recognition of amino acids in the presence of the macrocycle was based on diastereomeric complexes. Results demonstrated that TBRM had better chiral discrimination ability for lysine as compared to the other amino acids.

Transcendental Eigenvalue Problems Associated With Vibration, Buckling And Control, Jayaram Subramanian Jan 2007

Transcendental Eigenvalue Problems Associated With Vibration, Buckling And Control, Jayaram Subramanian

LSU Master's Theses

The static and dynamic analysis of structures requires us to obtain solutions of their espective governing differential equations subject to appropriate boundary conditions. The dynamic analysis of non-uniform continuous structures is of primary interest, as most traditional methods take the help of discrete models to analyze them. Well established discrete model methods lead to an algebraic eigenvalue problem, the characteristic equation associated with which is a polynomial. The spectral characteristics of a continuous system nevertheless are represented by transcendental functions and cannot be approximated by polynomials efficiently. Hence finite dimensional discrete models are not capable of predicting the response of …

Pre-Treatment Of Dynamically Varying Waste Gas Concentrations Using Activated Carbon Prior To Biofiltration: Effect Of Cycle Length On Degree Of Load Equalization, Kodi L. Collins Jan 2007

Pre-Treatment Of Dynamically Varying Waste Gas Concentrations Using Activated Carbon Prior To Biofiltration: Effect Of Cycle Length On Degree Of Load Equalization, Kodi L. Collins

LSU Master's Theses

Dynamically varying waste gas concentrations pose challenges to the operation and design of air pollution control techniques such as biofilters. Although design approaches are becoming well established for biofilters treating gases containing VOC concentrations that are constant as a function of time, many industrial processes emit gas streams contaminated with volatile organic compounds at concentrations that fluctuate with time. Application of an effective load equalization technique could eliminate some challenges associated with fluctuating pollutant concentrations. Recent research has demonstrated that granular activated carbon (GAC) can serve as a passively controlled system to provide load-equalization as a pre-treatment prior to biofiltration. …

A Return To Civilian Leadership: New Orleans 1865-1866, Arthur Wendel Stout

LSU Master's Theses

In the aftermath of the Civil War, southern cities such as New Orleans had to reconstitute local civilian government under extremely difficult circumstances. Different aspects of their physical infrastructure had been worn down and required revitalization. Sudden changes in the size and demographics of the population made social cohesion and provision of services more difficult and complicated. A depressed economy limited the financial resources available to government and business to confront the needs of growth. These recovery problems were common to all areas of the South, but in New Orleans they were greatly exacerbated by the city’s unusually high population …
