A Stellar Parameter Calibration Of Iue Data For The Determination Of The Present Day Mass Function Of High Mass Stars, Kenneth Thomas Taylor Jan 2003

A Stellar Parameter Calibration Of Iue Data For The Determination Of The Present Day Mass Function Of High Mass Stars, Kenneth Thomas Taylor

LSU Master's Theses

A study of stellar atmosphere models and the photometric quantity R is presented here, with R being the ratio of the integrated de-reddened fluxes from the two wavelength regions of the International Ultraviolet Explorer (IUE) satellite cameras. The effective temperatures and surface gravities of the stellar atmospheres were calibrated against R and absolute magnitude, using stellar evolution tracks from the literature, and applied to over 156 LMC stars whose masses and mass function are then derived from the results. The results show that the effective temperatures and surface gravities of stars derived from R and absolute magnitude correlate well with …

Pcr Inhibition And Toxic Effects By Sediment Samples Exposed To Drilling Muds, Neal Gilpin Satterly Jan 2003

Pcr Inhibition And Toxic Effects By Sediment Samples Exposed To Drilling Muds, Neal Gilpin Satterly

LSU Master's Theses

This study evaluated the PCR inhibition and toxic effects by sediment samples exposed to drilling muds. This information was gathered in an attempt to identify what effect, if any, drilling muds had on the microbial community structure in sediments around four specific oil-drilling platforms in the Gulf of Mexico. Sediment samples were taken before and after drilling had taken place around two platforms (GB516 and VK916), and sediment samples were taken after drilling had taken place around two other platforms (MC292 and GB602). After using traditional, non-selective DNA extraction methods, successful amplification took place via PCR with all pre-drilling samples …

Effectiveness Of Copper-Oxide Wire Particles On The Control Of Haemonchus Contortus In Sheep, Ariane Diane Watkins Jan 2003

Effectiveness Of Copper-Oxide Wire Particles On The Control Of Haemonchus Contortus In Sheep, Ariane Diane Watkins

LSU Master's Theses

Among the gastrointestinal nematode parasites that cause the most problems to small ruminants, Haemonchus contortus is one of major concern. Currently, the control of H. contortus and others is almost entirely based on the use of anthelmintics. Consequently, anthelmintic resistance has developed worldwide and this has become a serious problem in small ruminant nematode parasite control programs. In view of this, there is a need for alternative control methods. The use of Copper-Oxide Wire Particles (COWP) to help reduce parasite burden is one such alternative. Three trials were conducted to determine the effect of COWP on the reduction of H. …

Truth's Veil: Language And Meaning In Merleau-Ponty And Derrida, Helen Troy Mellon Jan 2003

Truth's Veil: Language And Meaning In Merleau-Ponty And Derrida, Helen Troy Mellon

LSU Master's Theses

The linguistic structuralism of Ferdinand de Saussure (1857-1913) attracted the attention of Maurice Merleau-Ponty, prompting what is thought to be Merleau-Ponty’s “linguistic turn” of 1947. Saussure’s theory of the self-referential structure of linguistic signs as constitutive of value, was tied by Merleau-Ponty to his conception of the structure of intercommunication as constitutive of human value and meaning. Jacques Derrida, in the 1960s, also appealed to Saussure’s theory in formulating his thesis of a deferring and differing relationship between linguistic signs as constitutive of meaning, but rejected what he saw as the privileging of a metaphysics of presence-to-meaning in Saussure. One …

Feasibility Of Restoring The Louisiana Black Bear (Ursus Americanus Luteolus) To Portions Of Their Former Range, Kyle Ryan Van Why Jan 2003

Feasibility Of Restoring The Louisiana Black Bear (Ursus Americanus Luteolus) To Portions Of Their Former Range, Kyle Ryan Van Why

LSU Master's Theses

Black bears (Ursus americanus) historically occurred throughout much of North America’s forested landscapes, but loss of critical habitat and overharvest significantly reduced abundance and distribution. In the southeastern United States, black bear conservation has become a high priority and restoration has been suggested y to recolonize suitable habitat. My study focused on evaluating restoration of the Louisiana black bear (U. americanus luteolus) to the Red River Complex (RRC) in east-central Louisiana. This involved translocating female bears with new born cubs from source populations within Louisiana and monitoring their movements, habitat use, and social acceptance of the restoration program to determine …

Development And Implementation Of Fine Structure Aerosol Spectrum Coagulation Kernels And Deposition Mechanisms Using Advanced Nodal Method In The Caerot Code, Hyeongkae Park Jan 2003

Development And Implementation Of Fine Structure Aerosol Spectrum Coagulation Kernels And Deposition Mechanisms Using Advanced Nodal Method In The Caerot Code, Hyeongkae Park

LSU Master's Theses

Aerosol transport in confined spaces was studied via numerical simulation using the dynamic aerosol equation, which is Boltzmann?s transport equation at the hydrodynamic limit. Until recent years, there existed no comprehensive computational tool to predict the spatial distribution and time evolution of aerosol size spectrum. A previously developed code, INDASOL3D, solves the dynamic aerosol equation by using a homogenized control-volume based finite difference method applying the group sectional method on the coagulation dynamics. However, quantitative correctness has not been satisfactory. In this thesis, two new codes (SAEROSA, and CAEROT) were developed. SAEROSA computes the time evolution of the size spectrum …

Perceptions Of Classical Armenia: Romano-Parthian Relations, 70 Bc-Ad 220, John Joseph Poirot, Iii Jan 2003

Perceptions Of Classical Armenia: Romano-Parthian Relations, 70 Bc-Ad 220, John Joseph Poirot, Iii

LSU Master's Theses

Relative to its importance, little research has been done on the Romano-Parthian rivalry that existed during the first two centuries AD. By extension, even less has been written concerning the kingdom of classical Armenia, which often served as the focal point of that bitter conflict. The absence of such research is regrettable, for it was this very rivalry that dictated how the Empire’s eastern border would be defined. According to many modern scholars and several of the classical authors, Romans feared the looming threat of the Parthian state. Although such panic was unfounded, this fear supposedly then prompted the Empire’s …

Print Media Impact On State Legislative Policy Agendas, Abby Kral Jan 2003

Print Media Impact On State Legislative Policy Agendas, Abby Kral

LSU Master's Theses

Using a survey of Louisiana’s State Legislature, this study examined the role media have in developing state legislators’ policy agendas by exploring the function of news media in the public policy process. The study also tested whether there was a correlation between media use, years of legislative service, and education level. This thesis was also able to establish a correlation between media use and gender, with results suggesting that female state legislators rely on newspapers more than their male counterparts. The results suggest that legislators do seek out issues in newspapers that affect the communities and constituents they serve and …

Optimal Age At Fostering For The Derivation Of Helicobacter Hepaticus-Free Mice, Kem Boullion Singletary Jan 2003

Optimal Age At Fostering For The Derivation Of Helicobacter Hepaticus-Free Mice, Kem Boullion Singletary

LSU Master's Theses

Helicobacter hepaticus is well established as an unwanted variable in laboratory rodent colonies. Historically, caesarean section and embryo transfer have been used to derive Helicobacter-free mouse colonies. Neonatal transfer of newborn mice onto Helicobacter-free foster dams was recently reported as an alternative method of deriving Helicobacter-free mice, but until now, the age by which pups must be fostered to remain Helicobacter-free was unknown. The purpose of this study was to determine the age by which mouse pups must be fostered to remain H. hepaticus-free. Beginning on the day of birth, 20 C57BL/6 mice were fostered from H. hepaticus-positive parents onto …

The Roles Of Silanes As Coupling Reagents And In Deoxygenative Alkylations, Andrea S. Dupre Jan 2003

The Roles Of Silanes As Coupling Reagents And In Deoxygenative Alkylations, Andrea S. Dupre

LSU Master's Theses

Silane reagents play important roles in many areas of organic synthesis. This is primarily due to the ability of silanes to bond to more ligands than the traditional four to become hypervalent (i.e. penta- or hexavalent). This hypervalency causes the silicon center to become more Lewis Acidic and causes the formation of carbon nucleophiles from organosilane ligands. These nucleophiles have been used to perform many cross-coupling reactions with organohalide reagents. The research presented in this thesis reports the utility of silane reagents in cross-coupling reactions of Grignard reagents with alkyl halides. This cross coupling was desirable because the silane should …

Thermohydrodynamic Analysis Of Compressible Gas Flow In Compliant Foil Bearings, Zhengchun Peng Jan 2003

Thermohydrodynamic Analysis Of Compressible Gas Flow In Compliant Foil Bearings, Zhengchun Peng

LSU Master's Theses

This thesis deals with the development of mathematical models and numerical schemes for simulating the hydrodynamic pressure and temperature rise of compliant foil bearings lubricated by a thin gas film in between its compliant bearing surface and the rotating shaft. The model accounts for the compressibility of gas, the compliance of the bearing surface, and the interaction between the pressure field and temperature field of the gas film in the bearing system. Numerical solutions obtained over a fairly large range of operating speeds show excellent agreement with existing experimental data from both load performance test and bearing temperature measurement.

Forced Bubble Columns, Jia Ma Jan 2003

Forced Bubble Columns, Jia Ma

LSU Master's Theses

In many chemical, biochemical and pharmaceutical industrial processes, bubble breakage is very important for gas component to dissolve and react with surrounding liquid. The overall mass transfer performance can be improved greatly when the interfacial gas-liquid area is increased due to bubble breakup. In forced bubble columns operating at low forcing frequency (<30Hz) and small forcing amplitude (<3mm), bubbles undergo phenomenal breakage. Mass transfer coefficient, kLa, is increased to 250%~625% of the no forcing value depending on flow regime and configuration of membrane and piston. Two different mechanisms, induced shear slug breakage in the gas feeder tube for bubbly flow and resonant frequency bubble breakage in the column fluid phase for jet flow, seem to at work.

Phosphorus Transport And Variability In Two Louisiana Coastal Plain Soils, Gregory Joseph Waldron Jan 2003

Phosphorus Transport And Variability In Two Louisiana Coastal Plain Soils, Gregory Joseph Waldron

LSU Master's Theses

Soil phosphorus (P) build-up from long-term application of poultry litter may increase P loss in surface and subsurface water and lead to eutrophication. Anoxic conditions during water saturation may aggravate the problem by increasing P solubility and mobility. However, the same level of soil P at different locations may not yield equal runoff P if the capacity of the soil to retain P varies across the landscape. This study examined: 1) effects of soil water oxygenation and concentration of soil organic matter (SOM) on development of anoxic conditions leading to decreased P sorption and increased mobility in a Ruston (fine-loamy, …

Estimation Of Waterfowl Food Abundance In Coastal Freshwater Marshes Of Louisiana And Texas, Christian Jesse Winslow Jan 2003

Estimation Of Waterfowl Food Abundance In Coastal Freshwater Marshes Of Louisiana And Texas, Christian Jesse Winslow

LSU Master's Theses

Food abundance might limit survival or recruitment of wintering waterfowl. Nutritional requirements of wintering waterfowl have been estimated, but there are insufficient data on the abundance of seeds and submerged aquatic vegetation (SAV) to determine if enough habitat exists to support target populations of waterfowl throughout winter. I estimated waterfowl food abundance at 14 coastal freshwater marsh sites in Texas and Louisiana from August 2001 to March 2003, and tested the hypothesis that wintering waterfowl reduce food abundance. I analyzed 210 and 360 seed and SAV samples, respectively, taken during September 2001, February 2002, September 2002, and February 2003 to …

Quantifying Habitat Quality Of Larval Bay Anchovy (Anchoa Mitchilli) In Chesapeake Bay By Linking An Individual-Based Model With Spatially-Detailed Field Data, Aaron Thomas Adamack

LSU Master's Theses

Larval bay anchovy (Anchoa mitchilli) habitat quality in Chesapeake Bay was predicted using an individual-based model applied to spatially-detailed field data from Rilling and Houde (1999). Habitat quality was predicted using the ratio of instantaneous mortality rate to instantaneous growth rate. Model predictions of habitat quality were compared to field estimates of habitat quality derived from the spatially-detailed field data. Three sets of one-day simulations were performed to estimate larval growth and mortality rates throughout Chesapeake Bay during June and during July 1993. Field-based simulations used field data to estimate the model inputs of water temperature, zooplankton densities, and the …

As The Ravens Watch: Exploring The Oracle, Kathryn Lavender Hunter Jan 2003

As The Ravens Watch: Exploring The Oracle, Kathryn Lavender Hunter

LSU Master's Theses

I believe in the process in which the artist never works alone but always in collaboration with the elements of chance. As an artist I live and work everyday collaborating with chance, from reading my cards to creating ethereal birds. As I sew pieces together, the thread becomes another element of the image by chance, stitches to lines, lines to pattern. Chance leads the birds to portraying their own personality as they are each created, one’s head tilts to the right while another sits tall with dignity. This work is about the connection to the subconscious, my connection to it …

Denoising Techniques - A Comparison, Sarita Veera Dangeti Jan 2003

Denoising Techniques - A Comparison, Sarita Veera Dangeti

LSU Master's Theses

Visual information transmitted in the form of digital images is becoming a major method of communication in the modern age, but the image obtained after transmission is often corrupted with noise. The received image needs processing before it can be used in applications. Image denoising involves the manipulation of the image data to produce a visually high quality image. This thesis reviews the existing denoising algorithms, such as filtering approach, wavelet based approach, and multifractal approach, and performs their comparative study. Different noise models including additive and multiplicative types are used. They include Gaussian noise, salt and pepper noise, speckle …

Who Helps In A Crisis: Differentiating Among Adult Children As Sources Of Support For Their Caregiving Mothers, Michael J. Patterson Jan 2003

Who Helps In A Crisis: Differentiating Among Adult Children As Sources Of Support For Their Caregiving Mothers, Michael J. Patterson

LSU Master's Theses

This thesis uses a combination of quantitative and qualitative data collected from 134 mothers about their relationships with 381 adult children during the first few months after the mothers began caring for a spouse or older parent. Building on a framework that draws on theories of social structural similarity, I anticipated that adult children who shared more social statuses with their parents would be more likely to be sources of emotional and instrumental support and less likely to be sources of interpersonal stress to their caregiving mothers. Multivariate analyses revealed no effects of structural similarity and few effects of other …

Supply Chain Models For An Assembly System With Preprocessing Of Raw Materials, Mohammad Anwar Ashek Rahman Jan 2003

Supply Chain Models For An Assembly System With Preprocessing Of Raw Materials, Mohammad Anwar Ashek Rahman

LSU Master's Theses

An assembly line that procures raw materials from outside suppliers and processes the materials into finished products is considered in this research. An ordering policy is proposed for raw materials to meet the requirement of a production facility, which, in turn, must deliver finish products in a fixed quantity at a fixed time interval to the outside buyers. Two different types of raw materials, ‘unfinished’ and ‘ready-to-use’, are procured for the manufacturing system. The ‘unfinished raw materials’ are turned into ‘processed raw materials’ after preprocessing. In the assembly line, the ‘processed raw materials’ and the ‘ready raw materials’ are assembled …

Physical Function And Quality Of Life In The Very- And Oldest-Old: Gender Differences, Kellye A. Ferachi Jan 2003

Physical Function And Quality Of Life In The Very- And Oldest-Old: Gender Differences, Kellye A. Ferachi

LSU Master's Theses

Age is associated with deterioration in physical function (PF) and health-related quality of life (HRQL). Recent investigations suggest that a decrease in function may have a greater impact on perceived activities of daily living (ADL) competency in women than in men. The purpose of this investigation was to test the hypothesis that the association between PF and HRQL among older adults is influenced by gender. We examined 108 older adults aged 60 years or older, for PF (Continuous Scale-Physical Function Performance test (CS-PFP10) and Functional Status Index (FSI)) and HRQL (SF-36). In order to address this question we assigned subjects …

Habitat Assessment And Subspecies Identification Of Sandhill Cranes Wintering In Louisiana, Joseph Michael Mcgowan Jan 2003

Habitat Assessment And Subspecies Identification Of Sandhill Cranes Wintering In Louisiana, Joseph Michael Mcgowan

LSU Master's Theses

The two biggest flocks of Sandhill Cranes (Grus canadensis) wintering in Louisiana are located in Cheneyville and Holmwood, LA. Resident Sandhill Cranes were once located in Louisiana, but because of habitat loss and over harvest these residents were extirpated from Louisiana in the early 1900’s. In the 1960’s, migrating Sandhill Cranes had returned to LA and were wintering in Cheneyville. Observations and habitat characteristics were conducted on these two flocks in the winter of 2002 and 2003 because of the lack data on these flocks. The two flocks contained about 1,300 individuals with four other known flocks throughout Louisiana ranging …

The Attack Will Go On The 317th Infantry Regiment In World War Ii, Dean James Dominique Jan 2003

The Attack Will Go On The 317th Infantry Regiment In World War Ii, Dean James Dominique

LSU Master's Theses

The 317th Infantry Regiment was reactivated on July 15, 1942 as a subordinate element of the 80th Infantry Division. The regiment trained for two years in Tennessee, Kansas, Arizona, California, and finally New Jersey before departing for England in June 1944. Entering the European continent after D-Day, the regiment experienced its first combat in August 1944 when it assisted in closing the gap at Falaise and spearheaded Third Army's attack on Nancy. The 317th sat through the logistics shortfall that stopped the Third Army's advance during the "October Pause" in the fall of 1944. But then in November the regiment …
