Survival, Habitat Use, And Movements Of Female Mallards Wintering In Southwestern Louisiana, Paul Thomas Link Jan 2007

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 …

Feral Swine Action Plan For Oregon, Mark Sytsma, Arick Christopher Rouhe Jan 2007

Feral Swine Action Plan For Oregon, Mark Sytsma, Arick Christopher Rouhe

Center for Lakes and Reservoirs Publications and Presentations

Feral swine are defined as free roaming animals of the genus Sus that are not being held under domestic management or confinement. Swine have spread from Europe and Russia to habitats around the world via human introduction. Currently, feral swine populations are established on every continent except Antarctica. Unlike other large mammal invaders, swine have a high reproductive capacity and are omnivorous, which allows for a quick assimilation into most habitats. Once a breeding population is established in an area, the population can quickly increase and negatively impact the ecosystem. A successful invasion of feral swine is difficult, and sometimes …

Deficits In Social Skills And Feeding Behaviors Associated With Adults Diagnosed With Autistic Disorder Living In An Institutionalized Setting, Cindy Terlonge Graham Jan 2007

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, …

Paleoceanography Of The Gulf Of Papua Using Multiple Geophysical And Micropaleontological Proxies, Lawrence A. Febo Jan 2007

Paleoceanography Of The Gulf Of Papua Using Multiple Geophysical And Micropaleontological Proxies, Lawrence A. Febo

LSU Doctoral Dissertations

Recent marine and late Pleistocene sediments examined from the Gulf of Papua (GoP), Papua New Guinea investigate the flux and fate of detrital sediments and organic carbon over the last glacial-interglacial cycle. Based on surface sediment magnetic susceptibility (MS) and calcium carbonate concentrations, recent marine sediment is exported off the narrow shelf and into deeper regions via the Kerema Canyon of the northern Pandora Trough. Detrital clastic sediment is then dispersed deeper into the central and southern Pandora Trough. Except for pelagic deposition, very little detrital material reaches the Ashmore Trough and Eastern Plateau adjacent to the Great Barrier Reef. …

The Search Interest In Contract, Joshua Fairfield Jan 2007

The Search Interest In Contract, Joshua Fairfield

Articles by Maurer Faculty

Parties often do not negotiate for contract terms. Instead, parties search for the products, terms, and contractual counterparties they desire. The traditional negotiation-centered view of contract leads courts to try to determine the meaning of the parties where no meaning was negotiated and to waste time determining the benefits of bargains that were never struck. Further, while courts have ample tools to validate specifically negotiated contract terms, they lack the tools to respond to searched-for terms. Although the law and literature have long recognized that there is a disconnect between the legal fictions of negotiation and the reality of contracting …

Synaptic Boojums: Lewis Carroll, Linguistic Nonsense, And Cyberpunk, Jennifer Kelso Farrell Jan 2007

Synaptic Boojums: Lewis Carroll, Linguistic Nonsense, And Cyberpunk, Jennifer Kelso Farrell

LSU Doctoral Dissertations

Tracing a line from Lewis Carroll to 20th-century science fiction and cyberpunk, this project establishes an alternate genealogy based on the use of linguistic nonsense. Science fiction, rather than being merely a genre defined by specific narrative devices or character traits, is instead a language in and of itself. And like any language, it must be learned in order to be understood. Carroll used nonsense as a means of subverting conventional 19th-century opinions of language and, and by extension, society. Carroll was so successful at this that in 1937 American psychiatrist Paul Schilder discussed the dangers to a child's mind …

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. Partial-least-squares regression modeling (PLS-1) of spectral data for macrocycle-lysine host-guest complexes …

The Apologia Of Franchino Gafurio: A Critical Edition And Translation, Patrick Joseph Kaufman Jan 2007

The Apologia Of Franchino Gafurio: A Critical Edition And Translation, Patrick Joseph Kaufman

LSU Master's Theses

Franchino Gafurio’s Apologia (Turin, 1520) is one musical treatise in a series of works that constituted the famous “pamphlet war” between he and Giovanni Spataro. The dispute originated with the publication of Bartholomeo Ramis de Pareia’s Musica practica (Bologna, 1482). Unconventional and unapologetically critical, Ramis rejected venerated musical traditions in an attempt to align music theory with contemporary music practice. He opposed the Pythagorean division of the monochord and Guidonian solmization syllables, and instead proposed a division which produced pure thirds, and a solmization system based on the octave. His iconoclastic proposals and his highly sarcastic tone called forth a …

Subrepresentation Semirings And An Analogue Of 6j-Symbols, Nam Hee Kwon Jan 2007

Subrepresentation Semirings And An Analogue Of 6j-Symbols, Nam Hee Kwon

LSU Doctoral Dissertations

Let G be a quasi simply reducible group, and let V be a representation of G over the complex numbers $mathbb{C}$. In this thesis, we introduce the twisted 6j-symbols over G which have their origin to Wigner's 6j-symbols over the group SU(2) to study the structure constants of the subrepresentation semiring S_{G}(End(V)), and we study the representation theory of a quasi simply reducible group G laying emphasis on our new G-module objects. We also investigate properties of our twisted 6j-symbols by establishing the link between the twisted 6j-symbols and Wigner's 3j-symbols over the group G.

The Application Of Controlled Radical Polymerization Processes On The Graft Copolymerization Of Hydrophobic Substituents Onto Guar Gum And Guar Gum Derivatives, Veronica Holmes

LSU Doctoral Dissertations

Guar gum is a naturally occurring polysaccharide; guar gum and its derivatives, such as carboxymethyl guar gum (CMG) are widely used in the oil and gas industry. A hydraulic fracturing fluid for rock formations to enhance oil recovery (EOR) is comprised of viscosifier, gelled CMG, and sand particles (proppants). The gel is mixed with proppant (sand) and pumped at high rate and high pressure into an oil/gas well to the hydrocarbon-producing zone. The applied pressure will force the rock formation to fracture allowing entry of the guar gel/sand mixture. The mixture then fills the resultant fracture. The viscosity of the …

Passive Alignment Of Micro-Fluidic Chips Using The Principle Of Elastic Averaging, Sitanshu Gurung Jan 2007

Passive Alignment Of Micro-Fluidic Chips Using The Principle Of Elastic Averaging, Sitanshu Gurung

LSU Master's Theses

This thesis presents a novel design for a passive alignment feature for vertically stacking chips in a micro fluidic device. Each chip is the size of a standard microscopic slide (75mm—25mm) and is a highly specialized functional unit designed and fabricated to process fluidic samples. The fluidic samples in the device flows from one chip to another using inter connecting holes 500μm-100μm in diameter. Hence an alignment of better than 100μm between chips is necessary to allow for the interconnecting holes to overlap so as to provide with a path for the fluid to flow. The feature to be used …
