The Effect Of Periodic Operation On Biofilters For Removal Of Methyl Ethyl Ketone From Contaminated Air, Charles William Norman Jan 2002

The Effect Of Periodic Operation On Biofilters For Removal Of Methyl Ethyl Ketone From Contaminated Air, Charles William Norman

LSU Master's Theses

In recent years, biofiltration technology has been used at numerous locations worldwide as an air pollution control technology for treating gases contaminated with low concentrations of biodegradable volatile organic compounds (VOCs). At the same time, there have been many reports in the literature of contaminant emissions from biofilters during transient loading conditions. There is currently a need to develop methods for controlling such emissions. Periodically operated bioreactors have been used successfully in treatment of wastewater and soils for several decades to mitigate the effects of uncontrolled unsteady-state loading on waste treatment systems. Such operating strategies have only recently been applied …

Perception Of And Reactions To The Presence Of Url's In Print Advertising Of A Non-Technology Brand, Neil Melancon Jan 2002

Perception Of And Reactions To The Presence Of Url's In Print Advertising Of A Non-Technology Brand, Neil Melancon

LSU Master's Theses

This thesis, through an experiment of 108 subjects, studies the relationship between the presence of a Uniform Resource Locator (URL or web address) in newspaper advertisements and perception of the product advertised as well as the likelihood to act on the advertisement. The findings reveal URLs do in fact have an effect on perception, although, as it is suggested in the theoretical framework, it does not necessarily induce the subjects to act on the ad. This study also finds there is a stronger inclination for perception change to take place versus the likelihood for consumers to either seek more information …

In-Vitro Gene Disruption Using Tn7-Based Transposition: Evaluation Of Its Utility And Efficiency In Generating A Brucella Virb1 Knockout, Jeffrey W. Mercante Jan 2002

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 …

Evaluation Of Feeding Chlamydospores Of Duddingtonia Flagrans To Ewe/Lamb Pairs And Weaned Lambs To Biologically Control Levels Of Haemonchus On Pasture, Natalee Peart

LSU Master's Theses

Gastroenteritis caused by the nematode parasite Haemonchus contortus is a serious concern for small ruminants in the tropics and subtropics. Control is traditionally by anthelmintics and pasture management, however this specific nematode parasite has become resistant to many anthelmintics and research is now focused on novel control methods including biological control using the nematode-trapping fungus, Duddingtonia flagrans. The objective of this study was to investigate the effectiveness of feeding chlamydospores of the fungus at a dosage of 5 x 105 spores/kg of BW to ewe/lamb pairs (Trial 1) and weaned lambs (Trial 2) for a total of 17 and 8 …

Movement Along The Baton Rouge Fault, Araya Eshetu Kebede Jan 2002

Movement Along The Baton Rouge Fault, Araya Eshetu Kebede

LSU Master's Theses

The Baton Rouge fault is one of two faults (the other being Denham Spring-Scotlandville fault) that traverse the city of Baton Rouge and has long been thought to be active. Structural damages to buildings, streets and sidewalks near the fault have previously been attributed to movement of the fault. Although the presence of the fault has been known for nearly 60 years, previous investigations have failed to determine its rate of movement. This study was aimed at determining the rate of modern movement along the Baton Rouge fault. Using a precise geodetic leveling technique, the current elevations of NGS (National …

Aspects Of Jazz And Classical Music In David N. Baker's Ethnic Variations On A Theme Of Paganini, Heather Koren Pinson Jan 2002

Aspects Of Jazz And Classical Music In David N. Baker's Ethnic Variations On A Theme Of Paganini, Heather Koren Pinson

LSU Master's Theses

David Baker's Ethnic Variations on a Theme of Paganini (1976) for violin and piano bring together stylistic elements of jazz and classical music, a synthesis for which Gunther Schuller in 1957 coined the term "third stream." In regard to classical aspects, Baker's work is modeled on Nicolo Paganini's Twenty-fourth Caprice for Solo Violin, itself a theme and variations. From Paganini,it borrows aspects of melody, harmony, and articulation, not only of the theme but also the variations. In regard to jazz, Baker transforms most variations (including the theme, which in comparison to Paganini's is already a variation) into distinct styles related …

Her Still Singing Limbs: A Collection Of Poetry, Anthony William Rintala Jan 2002

Her Still Singing Limbs: A Collection Of Poetry, Anthony William Rintala

LSU Master's Theses

"Her Still Singing Limbs: A Collection of Poetry" is a fragmented rumination on the intrinsic loneliness of the human condition. Using the Greek myth of Echo’s destruction at her beloved Narcissus’s hands as the foundation, these poems combine voyeuristic images of beauty and violence to explain why all poets write "songs of exquisite loneliness."

Nutrient Reserves Of Lesser Scaup During Spring Migration In The Mississippi Flyway: A Test Of The Spring Condition Hypothesis, Michael J. Anteau Jan 2002

Nutrient Reserves Of Lesser Scaup During Spring Migration In The Mississippi Flyway: A Test Of The Spring Condition Hypothesis, Michael J. Anteau

LSU Master's Theses

The continental scaup population (lesser [Aythya affinis] and greater scaup [A. marila] combined) has declined markedly during the past 20 years, and has remained below the population goal of the North American Waterfowl Management Plan since 1985. One hypothesis explaining the scaup population decline states that reproductive success has decreased because females presently are arriving on breeding areas in poorer condition than that historically (Spring Condition Hypothesis [SCH]). I tested the SCH by comparing fresh body masses (FBMs) and nutrient reserves (lipid, protein, and mineral) of lesser scaup at 4 locations (Louisiana, Illinois, Minnesota, and Manitoba) in the Mississippi Flyway …

Misguided By Experience: A Defense Of Custer's Actions At The Little Bighorn, Harold Douglas Baker Jan 2002

Misguided By Experience: A Defense Of Custer's Actions At The Little Bighorn, Harold Douglas Baker

LSU Master's Theses

At midday on June 25, 1876, Lieutenant Colonel George Armstrong Custer split his Seventh Cavalry Regiment into three elements and attacked an enormous village of hostile Indians situated along the Little Bighorn River in modern-day Montana. Custer and his immediate command of five troops, a total of 225 men, did not survive the fight. Immediately following the battle, officers-Reno, Benteen, Brisbin, Terry, Gibbon-began to recreate the history of the campaign's recent events in an effort to explain the disaster and clear themselves of responsibility. Their self-serving omission of facts and their convenient "remembrance" of things that had not happened fully …

Geostatistical Shale Models For A Deltaic Reservoir Analog: From 3d Gpr Data To 3d Flow Modeling, Hongmei Li Jan 2002

Geostatistical Shale Models For A Deltaic Reservoir Analog: From 3d Gpr Data To 3d Flow Modeling, Hongmei Li

LSU Master's Theses

The effects of shales on fluid flow in marine-influenced lower delta-plain distributary channel deposits are investigated using a three-dimensional ground-penetrating radar (GPR) data volume from the Cretaceous-age Ferron sandstone at Corbula Gulch in central Utah, USA. Using interpreted GPR data, we formulate a geostatistical model of the dimensions, orientations, and geometries of the internal structure from the subaerial exposure surface down to about 12 m depth. The correlation function between GPR instantaneous amplitude and shale index is built after statistical calibration of the GPR attributes (amplitude) with well data (gamma ray logs). Shale statistics are computed from this correlation function. …

Building Community: An Environmental Approach To Crime Prevention, Gustavo A. Barreto Jan 2002

Building Community: An Environmental Approach To Crime Prevention, Gustavo A. Barreto

LSU Master's Theses

Crime cannot be understood as a single-solution problem. Participation of the community is important to complement and make more efficient any program of crime control by police authorities or any other law enforcement agency. This thesis is intended to create consciousness among designers of the urban environment of their social role. Cities must include places to promote community interaction and formation of social bonds. As social bonds among residents increase, and bonds with the place begin building a sense of territoriality in the community, the residents become active defenders of the place against crime. A theory summary presents different and …

Hazard Analysis Critical Control Point (Haccp), Microbial Safety, And Shelf Life Of Smoked Blue Catfish (Ictalurus Furcatus), Ligia Virginia Antonia Da Silva Jan 2002

Hazard Analysis Critical Control Point (Haccp), Microbial Safety, And Shelf Life Of Smoked Blue Catfish (Ictalurus Furcatus), Ligia Virginia Antonia Da Silva

LSU Master's Theses

Quality deterioration of smoked catfish is caused by lipid oxidation and microbial spoilage. Smoked catfish can be cross-contaminated during processing and may harbor several pathogens, e.g., Listeria monocytogenes, and Salmonella spp. Lipid oxidation causes unpleasant flavor, thus making smoked fish unacceptable. Hydroperoxides and free radicals, formed during oxidation, may directly react with fish tissues to promote complex reactions. Through such complex reactions, physicochemical properties of smoked catfish may be adversely affected. A combination of smoking and treatments with antimicrobial agents and antioxidants would retard microbial spoilage, extend shelf life, and enhance safety of smoked catfish. The objective of this study …

Tension Lap Splice Lengths Of Carbon Fiber Reinforced Polymer Bars, Gregory Patrick Sepeda Jan 2002

Tension Lap Splice Lengths Of Carbon Fiber Reinforced Polymer Bars, Gregory Patrick Sepeda

LSU Master's Theses

With recent advances in the area of fiber reinforced polymers (FRP), more effort has been spent trying to incorporate the use of FRP in design applications. FRP bars offer both an ultimate strength and a corrosion resistance greater than traditional steel reinforcing. Fiber reinforced polymer bars can either consist of continuous glass (GFRP), aramid (AFRP) or carbon fibers (CFRP). CFRP bars, while lighter than GFRP typically offer a much greater tensile strength. With the recent release of the American Concrete Institute’s first edition manual ACI-440.1R “Guide for the Design and Construction of Concrete Reinforced with FRP Bars” (2001), unified design …

A Model Of Heat And Mass Transfer In An Idealized Micro Heat Pipe, Jin Zhang Jan 2002

A Model Of Heat And Mass Transfer In An Idealized Micro Heat Pipe, Jin Zhang

LSU Master's Theses

Micro heat pipes have been used to cool computer chips, but their heat transfer coefficients are low compared with that of conventional heat pipes. To understand this deficiency, an idealized micro heat pipe is proposed that has simplified interfacial geometry but retains the essential physics. It is a long and narrow cavity of rectangular cross section with the bottom made of a wetting material and the top a non-wetting material. A wetting liquid fills the bottom half of the cavity, and its vapor fills the rest. This configuration ensures that the liquid-vapor interface is pinned at the contact line. Since …

The Division Of Domestic Labor In Taiwanese Households, Chiung-Yin Hu Jan 2002

The Division Of Domestic Labor In Taiwanese Households, Chiung-Yin Hu

LSU Master's Theses

Using the 1995-1996 Taiwan Social Survey, this research applied major perspectives developed in the United States, the economic resources model and the gender ideology model, to the division of household labor in Taiwan, where gender norms have been strongly influenced by traditional patriarchal thinking while rapid economic growth in the past two decades has improved women’s socioeconomic status. The results show that while men’s economic resources and the gender ideology can explain their housework participation relatively well, the same variables for women explained their share of the housework rather poorly. I also examined the gender display/deviance neutralization model but failed …

Control Of Food Intake And Body Weight Following Smoking Cessation In Premenopausal Women, Jamie Lynn Neal Jan 2002

Control Of Food Intake And Body Weight Following Smoking Cessation In Premenopausal Women, Jamie Lynn Neal

LSU Master's Theses

Women experience more weight gain than men postcessation and are more aware of nicotine’s weight suppressing effects than men. Postcessation weight gain in women can be largely accounted for by significant increases in high fat foods from pre- to postcessation. Overeating found in the luteal phase, further compounds the increased caloric intake found postcessation. Few studies have evaluated the long-term effects of smoking cessation on macronutrient content and weight gain; and most have relied on self-report data. This study used the Macronutrient Self-Selection Paradigm (MSSP) and Food Preference Questionnaire (FPQ) to assess food intake in 17 women in the luteal …
