Field Grown Cut Flower Production In Southern Louisiana, John Burke, Jr. Young Jan 2003

Field Grown Cut Flower Production In Southern Louisiana, John Burke, Jr. Young

LSU Master's Theses

Specialty cut flowers are nontraditional cut flowers used primarily in floral arrangements. Most specialty cut flowers are grown in an open field and production is dependent on a combination of climactic factors, which in turn affects the number of days to harvest and yield. Scheduled plantings of Celosia argentea var. cristata L., Helianthus annuus L., Zinnia elegans Jacq., and Gladiolus X hortulanus L. H. Bailey were conducted to determine the effect of time on the number of days to harvest and yield. Plants were grown in an open field from February to August in 2001 and 2002. Days to harvest …

Treatment Of Mixtures Of Methyl Ethyl Ketone (Mek) And Toluene Using Continuous And Sequencing Batch Operated Biofilters, Jorge C. Atoche

LSU Master's Theses

During the past decade, biofiltration has increasingly been applied as an air pollution control technology to minimize or eliminate emissions of volatile organic compounds from industrial sources. Although of the ability of this technology to maintain high removal efficiency during relatively steady conditions has been well established for many waste streams, a limitation of this technology has been its inability to maintain high removal efficiency during transient loading conditions typical of industrial operations. In the research described herein, a conventional continuous-flow biofilter (CFB) and a sequencing batch biofilter (SBB) were operated for more than 295 days to treat a model …

"You Stupid, Lazy Kid": Perceptions Of Verbal Aggressiveness In Older Adults, Jon M. Croghan

LSU Master's Theses

Young adults' stereotypes of older adults has been well-documented in communication literature, however, there has been a lack of research on the impact of message strategy on intergenerational interactions. The purpose of this study was to examine the relationship among three factors that previous research suggests should influence the activation of stereotypes toward a target: age, relational level, and message strategy. This study examines the role that message strategy, in this case, verbal aggressiveness, plays in activating young adults' (n = 186) negative stereotypes of older adults. The young adults' self-reported levels of trait verbal aggressiveness was positively correlated with …

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 …

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 …

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 …

Field Evaluation Of In-Situ Test Technology For Qc/Qa During Construction Of Pavement Layers And Embankments, Munir Darwish Nazzal Jan 2003

Field Evaluation Of In-Situ Test Technology For Qc/Qa During Construction Of Pavement Layers And Embankments, Munir Darwish Nazzal

LSU Master's Theses

With the coming changes from an empirical to mechanistic-empirical pavement design, it becomes essential to move towards changing the quality control/quality assurance (QC/QA) procedures of compacted materials from a unit weight-based criterion to a stiffness/strength based criterion. The non-destructive in-situ tests such as Geogauge, Dynamic Cone Penetrometer (DCP), and Light Falling Weight Deflectometer (LFWD) can be used as effective tools in the assessment of subsurface conditions and in evaluating the stiffness of pavement materials and embankment. This thesis evaluates the potential use of these three devices to reliably measure the stiffness characteristics of highway materials for possible application in the …

A Comparison Of Microbial Communities In Soil With And Without A Sugarcane Cropping, Carolyn Faye Savario Jan 2003

A Comparison Of Microbial Communities In Soil With And Without A Sugarcane Cropping, Carolyn Faye Savario

LSU Master's Theses

Sugarcane (inter-specific hybrids of Saccharum) is grown largely under long-term monoculture production in Louisiana. This can lead to a complex problem termed "yield decline" that results in poor root health and reduced productive capacity of sugarcane. This problem has been documented to be a limiting factor for sugarcane production in diverse regions, including Louisiana, Hawaii, Jamaica, and Australia. Previous work showed that biological factors affect root health and contribute to yield decline. The objectives of this study were to increase our understanding of microbial communities in sugarcane soils, to determine if there are differences in microbial communities associated with sugarcane …

Role Of Eintermediaries In The United States Paper Supply Chain, Sanna Maria Kallioranta Jan 2003

Role Of Eintermediaries In The United States Paper Supply Chain, Sanna Maria Kallioranta

LSU Master's Theses

In an attempt to streamline the paper supply chain, paper industry vertical business-to-business eMarketplaces were established to help industry players to decrease inefficiencies in their supply chains, to minimize negative effects of economic cyclicality, and to achieve better visibility. eMarketplaces rode the hype of revolutionizing the way in which industries conduct business, citing the cost savings achieved by expanded market reach, operational efficiencies, aggregated purchasing, and finding the least expensive suppliers. Adoption of eIntermediaries has been lower than expected in the paper industry and many of the paper vertical start-ups failed when the economy softened and the dot.com bubble burst. …

U.S. Regional Newspapers' Coverage On China's Entry Into The Wto--A Regional Economy Approach, Ying Kong Jan 2003

U.S. Regional Newspapers' Coverage On China's Entry Into The Wto--A Regional Economy Approach, Ying Kong

LSU Master's Theses

The purpose of this study is to examine whether a region's economy has an impact on regional coverage of China's WTO entry. It is predicted that regional newspapers vary in reporting this issue because of variation in the regional economic structure. The findings of the study support this prediction. A content analysis of 282 news articles in the U.S. regional newspapers finds that the regional economy can be a predictor of regional newspaper's coverage. For North Carolina, Illinois and California, significant differences exist in the regional coverage of China's WTO accession in terms of reference to key economic issue, reference …

Bureaucratic Influence In Congressional Roll-Call Voting, William Blair Jan 2003

Bureaucratic Influence In Congressional Roll-Call Voting, William Blair

LSU Doctoral Dissertations

The focus of this dissertation is on one of the many relationships that exist between the bureaucracy and government: decision-making by elected representatives and the political influence of government employees on their decision-making. Specifically, it is with bureaucrats and the degree to which they may utilize political influence to create a disproportionate influence over government policy and decision-making in the United States House of Representatives. I argue that the inherent qualities of bureaucrats suggest that they are significant and influential constituency for representatives. They are an identifiable constituency to representatives, and have the means and opportunity to wield political influence. …

Global Expression Analysis Of Deinococcus Radiodurans' Response To Ionizing Radiation: Irre Is A Novel Regulator Of This Response, Ashlee M. Earl

LSU Doctoral Dissertations

IRS24 is a strain of Deinococcus radiodurans carrying mutations in two loci, uvrA and irrE, rendering it sensitive to the lethal effects of UV and ionizing radiation. These sensitivities can be reversed by introducing the wild type irrE allele back into IRS24 via natural transformation. The irrE allele was localized to a 970bp region of D. radiodurans R1 Chromosome I containing one putative open reading frame, DR0167, and 179bp of upstream sequence. Subsequent sequence analysis of the irrE allele in IRS24 revealed a transition mutation at codon 111 of DR0167 (IrrE) resulting in an arginine to cysteine amino acid substitution. …

"Science In Skirts": Representations Of Women In Science In The "B" Science Fiction Films Of The 1950s, Bonnie Noonan Jan 2003

"Science In Skirts": Representations Of Women In Science In The "B" Science Fiction Films Of The 1950s, Bonnie Noonan

LSU Doctoral Dissertations

This project shows how central representations of women in science were to the “B” science fiction films of the 1950s and uses these films as valuable indicators for cultural analysis. I argue that the emergence of the modern American science fiction film in 1950 combined with the situation of post-W.W.II women in science to create a genre explicitly amenable to exploring the tension between a woman’s place in the home and her place in the work force, particularly in the fields of science. Out of a context of 114 “B” science fiction films produced between 1950 and 1966, I offer …

Application Of Mechanistic Models In Predicting Flow Behavior In Deviated Wells Under Ubd Conditions, Faisal Abdullah Aladwani

LSU Master's Theses

Underbalanced drilling (UBD) has increased in recent years because of the many advantages associated with it. These include increase in the rate of penetration and reduction of lost circulation and formation damage. Drilling of deviated and horizontal wells also increased since recovery can be improved from a horizontal or a deviated well. The drilling of deviated wells using UBD method will reduce several drilling related problems such as hole cleaning and formation damage. Prediction of flow and pressure profiles while drilling underbalanced in such wells will help in designing and planning of the well. The main aim of this research …
