In The Dark Woods I Lost My Way, Debbie Kupinsky Jan 2002

In The Dark Woods I Lost My Way, Debbie Kupinsky

LSU Master's Theses

When I had journeyed half our life's way, I found myself in a shadowed forest. For I had Lost the path that does not stray Ah, it is hard to speak of what it was, That savage forest, dense and difficult, Which even in recall renews my fear: So bitter-death is hardly so severe! Dante Alegheri Inferno Canto 1 Dante's passage refers to the losing of a spiritual path, but for me it refers to the destruction of the past, memory and self. My work deals with the loss of the past and the burdens of memory. It deals with …

Characteristic Avifauna Of White-Sand Forests In Northern Peruvian Amazonia, Jose Alvarez Alonso Jan 2002

Characteristic Avifauna Of White-Sand Forests In Northern Peruvian Amazonia, Jose Alvarez Alonso

LSU Master's Theses

Recently, it has been shown that the high species richness in western Amazonia is related to habitat heterogeneity. Some habitats are rapidly disappearing or deteriorating as a result of anthropogenic activities, resulting in loss of species. One such unique habitat is white-sand forest (hereafter WSF), which is patchily distributed and restricted to a few areas in the northern Peruvian Amazonia. Although it is known that these unique forests are rich in endemic plants, very few studies of the fauna or ecology of these habitats have been conducted. I evaluated and determined the species composition of the avifauna of the white-sand …

In-Vitro Gene Disruption Using Tn7-Based Transposition: Evaluation Of Its Utility And Efficiency In Generating A Brucella Virb1 Knockout, Jeffrey W. Mercante

LSU Master's Theses

A Tn7-based transposition system carrying a kanamycin resistance gene has been used to disrupt a known virulence gene of Brucella melitensis 16M and Brucella abortus 2308 in-vitro. The suicide plasmid pBAvirB1::kan-29 was created, in part, by cloning the B. abortus virB1 gene into a vector that is not stably maintained in Brucella spp. The cloned virB1 gene was then mutagenized by in-vitro transposition of a Tn7-based transposon. This construct was used in-vivo to insert a disrupted virB1 gene in place of the wild type virB1 found in B. abortus 2308 and B. melitensis 16M by homologous recombination. The resulting virB1 …

Decentralized And Adaptive Sensor Data Routing, Mengxia Zhu Jan 2002

Decentralized And Adaptive Sensor Data Routing, Mengxia Zhu

LSU Master's Theses

Wireless sensor network (WSN) has been attracting research efforts due to the rapidly increasing applications in military and civilian fields. An important issue in wireless sensor network is how to send information in an efficient and adaptive way. Information can be directly sent back to the base station or through a sequence of intermediate nodes. In the later case, it becomes the problem of routing. Current routing protocols can be categorized into two groups, namely table-drive (proactive) routing protocols and source-initiated on-demand (reactive) routing. For ad hoc wireless sensor network, routing protocols must deal with some unique constraints such as …

Effects Of Repeat Sampling In The U.S. Waterfowl Parts Collection Survey, Jesse G. Oetgen Jan 2002

Effects Of Repeat Sampling In The U.S. Waterfowl Parts Collection Survey, Jesse G. Oetgen

LSU Master's Theses

Age ratio estimates obtained annually by the Cooperative Waterfowl Parts Collection Survey (PCS) serve as important estimates of annual waterfowl recruitment. To determine if age and sex ratios are biased due to repeat sampling of hunters across years, I examined PCS data collected from 1991-2000. Mean seasonal harvest increased with number of consecutive years hunters responded to the PCS. Proportions of juveniles in the mallard (Anas platyrhynchos) harvest and harvest of all species combined decreased with increasing seasonal harvest level. Proportions of males in the harvest increased with increasing harvest level. Proportions of juveniles in the harvest of hunters responding …

Occurrence Of Degenerative Joint Disease In The Radius: Analysis Of Skeletal Remains From The Poole-Rose Ossuary, Mirenda Ann Parks Jan 2002

Occurrence Of Degenerative Joint Disease In The Radius: Analysis Of Skeletal Remains From The Poole-Rose Ossuary, Mirenda Ann Parks

LSU Master's Theses

This study focuses on radii excavated from the Poole-Rose ossuary and analyzes the occurrence and patterning of degenerative joint disease (DJD) on the proximal and distal joint surfaces. The Poole-Rose ossuary, located in eastern Ontario, is dated to A.D. 1550 +/- 50. The Poole-Rose population, dating to the Late Woodland period, were agricultural in their subsistence activities. The disarticulated patterning of the skeletal remains suggests this site was associated with the “Feast of the Dead,” a mass interment burial ceremony. This ceremony took place about every eight to twelve years. Frequencies of lipping, porosity, and eburnation were reported in degree …

Feeding Habits Of Blacktip Sharks, Carcharhinus Limbatus, And Atlantic Sharpnose Sharks, Rhizoprionodon Terraenovae, In Louisiana Coastal Waters, Kevin Patrick Barry Jan 2002

Feeding Habits Of Blacktip Sharks, Carcharhinus Limbatus, And Atlantic Sharpnose Sharks, Rhizoprionodon Terraenovae, In Louisiana Coastal Waters, Kevin Patrick Barry

LSU Master's Theses

Little is known regarding the feeding behavior of many shark species. Even less is known about shark feeding habits in Louisiana coastal waters. The stomach contents of gillnet-captured blacktip sharks (n=356), Carcharhinus limbatus, and Atlantic sharpnose sharks (n=55), Rhizoprionodon terraenovae, were examined in this study. Roughly half of the blacktip stomachs (52%) and sharpnose stomachs (45%) contained prey items. The primary prey item in terms of percent number, occurrence, and weight for blacktips and sharpnose was the gulf menhaden, Brevoortia patronus. Both blacktips and sharpnose appear to mainly be piscivores; however, no members of Sciaenidae, the most common family of …

Approaches To Measuring The Frequency Of Achondroplasia And Hypochondroplasia Causing Fgfr-3 Mutations In Human Sperm, Andrew Timothy Daters Jan 2002

Approaches To Measuring The Frequency Of Achondroplasia And Hypochondroplasia Causing Fgfr-3 Mutations In Human Sperm, Andrew Timothy Daters

LSU Master's Theses

Achondroplasia and hypochondroplasia are two forms of skeletal dysplasias caused predominantly by single base mutations in the fibroblast growth factor receptor 3 gene (FGFR-3). The mutation for achondroplasia is a G1138A/C substitution and the mutation for hypochondroplasia (occurring about 50% of the time) is a C1620A/G substitution. Recent genetic studies have shown that spontaneous mutations for achondroplasia and hypochondroplasia occur exclusively on the paternally derived chromosome, suggesting that these mutations occur preferentially during spermatogenesis. For unknown reasons, the mutation rates at these FGFR-3 nucleotides appear to occur at a much higher frequency than nucleotide specific mutation rates observed in other …

Christio-Conjure In Voodoo Dreams, Baby Of The Family, The Salt Eaters, Sassafrass, Cypress & Indigo, And Mama Day, Laura Sams Haynes Jan 2002

Christio-Conjure In Voodoo Dreams, Baby Of The Family, The Salt Eaters, Sassafrass, Cypress & Indigo, And Mama Day, Laura Sams Haynes

LSU Doctoral Dissertations

This project examines contemporary African American women’s literature and the legacy established by literary foremother, Zora Neale Hurston. The discussion is positioned at the cross-section of three on-going conversations: 1) current discourses on Conjure in African American women’s literature, 2) analyses of Africanisms in black culture, and 3) previous scholarship on recurring topics in African American women’s writing. Here these frames are unified under one thematic: Christio-Conjure—a rubric borne of the trans-Atlantic slave trade that designates the fusing of Christian and West African religious tradition in African American culture. Thus, this project establishes a new literary matrix for analyzing twentieth-century …

Enhanced Bioremediation Of 1,1,2,2-Tetrachloroethane In Wetland Soils, Jason S. House Jan 2002

Enhanced Bioremediation Of 1,1,2,2-Tetrachloroethane In Wetland Soils, Jason S. House

LSU Master's Theses

This research investigated the capability of wetland soils to function as a medium for the degradation of 1,1,2,2-TeCA and its daughter products, and the influence of different hydrogen donors and nutrients on this process. The rate constants calculated for this study, show that removal of 1,1,2,2-TeCA is occurring in the microcosms receiving hydrogen donors as well as the biotic controls. The parent compound was undergoing complete degradation to ethene, which was confirmed by ethene analysis, as well as monitoring the intermediate compounds. The analysis for the degradation products of 1,1,2,2-tetrachloroethene is important in determining the overall potential for successful degradation …

Development Of A Magnetite Tracer Protocol For Seasonal Measurement Of Bed Sediment Biodiffusion Coefficients, Paul D. Libbers Jan 2002

Development Of A Magnetite Tracer Protocol For Seasonal Measurement Of Bed Sediment Biodiffusion Coefficients, Paul D. Libbers

LSU Master's Theses

This thesis describes the development of a particle tracer technique for making short-term, in situ measurements of aquatic bed sediment biodiffusion coefficients. The bioturbation process in the upper sediment layers of streams, lakes, estuaries, and the marine environment moves particles and porewater. When present, organic chemicals, metals, colloids, etc., are transported across these layers and exchanges may occur at the sediment-water interface. Fickian biodiffusion coefficients that characterize such particle movements, Db (cm2/yr), are used for assessing chemical diagenesis rates and contaminant fluxes and are specific to each site. Chemical Fate and Transport (CFaT) models, developed for tracking contaminants in aquatic …

Development Of A Phosphorus Management Model To Address Filamentous Algae In A Shallow, Subtropical, Urban Hypereutrophic Lake, Jennifer Eileen Ruley

LSU Master's Theses

City Park Lake is a shallow, subtropical, urban hypereutrophic lake located in Baton Rouge, Louisiana. By the late 1970’s, this artificial lake had experienced extreme eutrophication and suffered from frequent algal blooms and fish kills. Restoration of City Park Lake occurred in 1983 and consisted of dredging nutrient-laden sediments and the rehabilitation of sewage pipelines. Pre- and post-restoration water quality monitoring programs have provided valuable information by which to gage the long-term success of the restoration work. Following the restoration effort, dramatic improvements were observed in the lake including lower nitrogen, phosphorus and chlorophyll-a concentrations, reduced frequencies in algal blooms …

Postmortem Interval (Pmi) Determination At Three Biogeoclimatic Zones In Southwest Colorado, Maria T. Allaire

LSU Master's Theses

Three pig (Sus scrofa L.) carcasses were exposed during the summer in three different biogeoclimatic zones ranging in elevations from 6,700 to 11,100 feet in order to determine the rates of carrion decomposition and arthropod succession patterns on carrion in southwest Colorado. The carcasses were exposed in three scenarios: sun-exposed, shaded, and sun-exposed/shaded. Of the total 63 taxa collected, thirty species overlapped between two biogeoclimatic zones. A strong elevational preference is indicated for the Sarcophagidae taxon. A previously undescribed Boettcheria species was collected at 11,100 feet. The rates of decomposition lengthened as elevation increased due to a prolongation of the …
