Double-Bond Isomerization Of Long Chain Olefins, James Edward Bruno

LSU Master's Theses

Bruno, James Edward, B.S., Western Michigan University, 2010 Master of Science, Fall Commencement, 2012 Major: Chemical Engineering Double-Bond Isomerization of Long Chain Olefins Thesis directed by Professor Kerry Dooley Pages in thesis, 54. Words in Abstract, 349. ABSTRACT Alkenyl Succinic Anhydride (ASA) is commonly used in the paper industry as a sizing agent. ASA is produced by reacting maleic anhydride with long-chain internal olefins. Such olefins are only available with the double bond in the terminal position, so an isomerization step is necessary. The isomerization can be catalyzed using solid strong acid catalysts, such as those containing sulfonic acid groups. …

Evading Legislative Jurisdiction, Austen L. Parrish

Articles by Maurer Faculty

In the last few years, and mostly unnoticed, courts have adopted a radically different approach to issues of legislative jurisdiction. Instead of grappling with the difficult question of whether Congress intended a law to reach beyond U.S. borders, courts have side-stepped it entirely. Courts have done so by redefining the definition of extraterritoriality. Significant and contentious decisions in the Ninth and D.C. Circuits paved the way by holding that not all regulation of overseas foreign conduct is extraterritorial. And then suddenly, last term, the U.S. Supreme Court breathed life into the practice. In its landmark Morrison v. National Australia Bank …

Evaluating The Differential Effects Of Parental Involvement On Check In/Check Out In Children With Externalizing Behavior Problems, Aaron Jason Fischer

LSU Master's Theses

School-based interventions are typically implemented based on a Response to Intervention model, i.e., a 3-tiered support system. Tier 1 provides universal support for all students; Tier 2 targets children who are at risk for developing problems; Tier 3 focuses on remediation for children with severe problems. The interventions in Tier 2 are important because they provide an opportunity to access children before their problems become critically dysfunctional. Check in/Check out (CICO) is a Tier 2 intervention that has been evaluated for children with externalizing behavior problems. In the current CICO literature, parent involvement during CICO integrates school and home life, …

Photojournalism As Photonationalism, Jeremy Kreusch

LSU Master's Theses

The public saw the wars in Iraq (2003 – 2012) and Afghanistan (2001 – present) through the lens of reverence and sentimentality toward the soldier. This was manifest not simply in the catchy “support our troops” rhetoric, but in the one-sided depiction of the experience of battle by the photojournalists who worked for the major news organizations in the Western world. From the emotionally bloated to the nationalistic, the photographs taken by “embedded” photojournalists, whether the result of heavy-handed censorship or merely political influence, presented a consistent image: the soldier as a selfless victim of his or her own heroism. …

"Condoms And Candy": Pro-Choice Students On Campus, Jordan Rebecca Kea

LSU Master's Theses

This thesis seeks to understand the dynamics of a feminist student organization within the context of a college campus in southern Louisiana. Through a methodology of participant observation, interviews, spot observations and archival research I examine how this pro-choice organization navigates campus public space. This project focuses on aspects of collaboration or collective action within a network of organizations, the participation of members, and the discursive processes of storytelling and audience effects. This collaborative ethnography also investigates how cross-sex interactions mediate topics of motherhood, abortion, and sexuality.  

Lung Carcinoma In The Era Of Personalized Medicine: The Role Of Cytology., Maureen F Zakowski, Marluce Bibbo

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

In 2004, three groups working independently [1–3] , almost simultaneously, reported remarkable findings: that activating mutations in the epidermal growth factor receptor (EGFR) were common in certain lung carcinomas and that these mutations correlated with the response of those lung tumors to therapy with gefitinib and erlotinib, both EGFR tyrosine kinase inhibitors (TKIs). This was the first time driver mutations in lung cancer that responded to targeted therapy had been identified, marking the beginning of a new era of personalized medicine in lung cancer. Prior to the discovery of these mutations, patients had been treated with EGFR TKIs but predicting …

Decorin Protein Core Affects The Global Gene Expression Profile Of The Tumor Microenvironment In A Triple-Negative Orthotopic Breast Carcinoma Xenograft Model., Simone Buraschi, Thomas Neill, Rick T Owens, Leonardo A Iniguez, George Purkins, Rajanikanth Vadigepalli, Barry Evans, Liliana Schaefer, Stephen C Peiper, Zi-Xuan Wang, Renato V Iozzo

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Decorin, a member of the small leucine-rich proteoglycan gene family, exists and functions wholly within the tumor microenvironment to suppress tumorigenesis by directly targeting and antagonizing multiple receptor tyrosine kinases, such as the EGFR and Met. This leads to potent and sustained signal attenuation, growth arrest, and angiostasis. We thus sought to evaluate the tumoricidal benefits of systemic decorin on a triple-negative orthotopic breast carcinoma xenograft model. To this end, we employed a novel high-density mixed expression array capable of differentiating and simultaneously measuring gene signatures of both Mus musculus (stromal) and Homo sapiens (epithelial) tissue origins. We found that …

Temporal Changes In Innate Immune Signals In A Rat Model Of Alcohol Withdrawal In Emotional And Cardiorespiratory Homeostatic Nuclei., Kate Freeman, Anthony Brureau, Rajanikanth Vadigepalli, Mary M Staehle, Melanie M Brureau, Gregory E Gonye, Jan B Hoek, D Craig Hooper, James S Schwaber

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: Chronic alcohol use changes the brain's inflammatory state. However, there is little work examining the progression of the cytokine response during alcohol withdrawal, a period of profound autonomic and emotional upset. This study examines the inflammatory response in the central nucleus of the amygdala (CeA) and dorsal vagal complex (DVC), brain regions neuroanatomically associated with affective and cardiorespiratory regulation in an in vivo rat model of withdrawal following a single chronic exposure.

METHODS: For qRT-PCR studies, we measured the expression of TNF-α, NOS-2, Ccl2 (MCP-1), MHC II invariant chain CD74, and the TNF receptor Tnfrsf1a in CeA and DVC …

Finding A Forum For North Korea, Morse Tan

Faculty Articles, Papers, and Other Scholarship

North Korea’s gross and systematic violations of human rights violate international law, including contravention of the treaties that North Korea itself has ratified (i.e., the International Covenant on Civil and Political Rights; the International Covenant on Economic, Social and Cultural Rights; the Convention on the Rights of the Child; and the Convention on the Elimination of All Forms of Discrimination Against Women). Nevertheless, a surprising dearth of legal scholarship exists with respect to arguably the worst human rights situation in the world. This Article analyzes possible tribunals to provide a measure of redress for the victims of these heinous violations …

Combination Of The Top Quark Mass Measurements From The Tevatron Collider, David Hedin

Faculty Articles, Papers, and Other Scholarship

The top quark is the heaviest known elementary particle, with a mass about 40 times larger than the mass of its isospin partner, the bottom quark. It decays almost 100% of the time to a W boson and a bottom quark. Using top-antitop pairs at the Tevatron proton-antiproton collider, the CDF and D0 Collaborations have measured the top quark’s mass in different final states for integrated luminosities of up to 5.8 fb-1. This paper reports on a combination of these measurements that results in a more precise value of the mass than any individual decay channel can provide. It describes …

Activist Cartoons Without Borders: The Political Cartoons Of Brazilian Artist Carlos Latuff, Orayb Najjar

Faculty Articles, Papers, and Other Scholarship

Brazilian cartoonist Carlos Latuff has been described by Allers in Menassat as `a one-man cartoon wrecking-ball when he hits the ink.' In the last few years of penning sharp cartoons, he `has been alternatively praised and vilified in the press for his depictions of suffering' in places like the Palestinian territories, Iraq, and the slums of Latin America. In this study, I use Latuff's work to illustrate how the artist has formed a global identity based on political affiliation, rather than national origin. I show how the `affordances' of the Internet, namely, the ability of non-mainstream individuals and groups to …

Commercial Burmanization: Two Adverts By Burmah Oil Company In Postcolonial Burma, Tharaphi Than

Faculty Articles, Papers, and Other Scholarship

Burma gained independence on 4 January 1948. Immediately after independence, Burmese media launched a campaign to ‘resurrect’ the country’s ‘lost’ culture. Bamakhit newspaper argued that the building of a new nation must be based upon customs, religion, and traditions that were indigenous.1 The new Burma needed to be built upon the foundations of Buddhism and cultures unique to the country. Indeed Burma not only had to recover its own customs, but also needed to distinguish, with the aim of discarding, cultures that were foreign to the country. In this article, I discuss how the (British-owned) Burmah Oil Company (BOC) used …

Hydraulic Conductivity Of The High Plains Aquifer Re-Evaluated Using Surface Drainage Patterns, W. Luo, D.T. Pederson

Faculty Articles, Papers, and Other Scholarship

The High Plains Aquifer (HPA), underlying parts of 8 states from South Dakota to Texas, is one of the largest fresh water aquifers in the world and accounts for 30% of the groundwater used for irrigation in the US. Determining the distribution of HPA's hydraulic conductivity (K) is critical for water management and addressing water quality issues. K is traditionally estimated from well pumping data coupled with computer modeling and is known to be highly variable, spanning several orders of magnitude for the same type of rock. Here we show that applying our innovative method of determining effective horizontal K …

The Spatial-Temporal Dynamics Of China’S Changing Urban Hierarchy (1950–2005), Xuwei Chen, Richard Greene

Faculty Articles, Papers, and Other Scholarship

This paper examines the dynamic spatial and temporal patterns of China’s urban hierarchy from 1950 to 2005. We limit the study to mainland China’s 137 urban agglomerations of 750,000 or more population as of 2005. The paper improves upon a classic approach to measuring shifting ranks within an urban hierarchy by applying advanced spatial analysis techniques. We use a Getis-Ord G∗ i , a space-timeMoran scatter plot, and dynamic LISA paths to examine the regional difference and change for these urban agglomerations. Our study revealed a north-south divide in the changing urban hierarchy of China after 1990. The analysis demonstrated …

Variations In Pore Water Salinities Above And Below Allochthonous Salt Sheets In The Deepwater Gulf Of Mexico: Implications For Mechanisms Of Solute Transport, Miles Alexander Mccammon

LSU Master's Theses

Spatial variations in salinity of pore waters in marine sediments provide useful information on processes and rates of subseafloor fluid flow and solute transport, particularly if there are evaporites in the section. Pore water salinities were determined for 18 drill holes which penetrated allochthonous salt bodies in 12 widely-scattered protraction blocks on the Louisiana offshore continental shelf and slope. Salinities were calculated from Log ASCII Standard-Logging While Drilling (LAS-LWD) logs using the Revil et al. (1998) dual-conductivity technique. The sites represent a wide range of field settings. Water depths range from 30 to 1990 m, depths to the top of …

Improving Middle School Math Achievement Using A Web-Based Program And Extended Written Tasks, Sarah Claire Dyer

LSU Master's Theses

This thesis outlines a dual-intensity approach using a web-based program, MyMathLab, for procedural fluency and, in parallel, extended written tasks for helping students improve their reasoning skills, to learn to use multiple representations, and securing mathematical knowledge. The new Common Core State Standards have increased expectations and achievement goals at all grade levels, the required changes being most significant at earlier grade levels (in elementary and middle schools). It is my assertion that a combined approach, one that encompasses both procedure-oriented practice for fluency and extended written tasks designed to stretch thinking and reasoning is needed to meet these goals.

Volunteer Based Organizations: Bridging The Gap Between Political Efficacy And Civic Engagement, Kristin Nicole Marks

LSU Master's Theses

With the declining participation in civic engagement behaviors such as voting, people are turning to other means to demonstrate civic participation. This study examined the role of volunteering as a means to establish civic engagement. Because of this civic participation behavioral shift, the relationship between civic engagement and the communication tactics used by volunteer based organizations was investigated. This study investigated the relationship between civic engagement and political efficacy. Additionally, this study examined the interplay between organizational characteristics (trust, control mutuality, exchange relationship, and commitment) and civic engagement. Lastly, perceptions of new and traditional methods of communications to encourage civic …

Consumer And Processor Methods To Control Salmonella And Listeria In Shrimp, Genevieve Anne Edwards

LSU Master's Theses

A common method used by consumers to determine if shrimp are thoroughly cooked when boiling, is to wait until the shrimp float to the top of the water and are pink in color. The purpose of this study was to determine whether the current floating and color cooking method is adequate to ensure the elimination of Listeria and Salmonella species. Furthermore, to determine if processing and storage methods reduce the effectiveness of this method. Shrimp samples were submerged into bacterial suspensions for 30 min then allowed to air dry for 1 hr and color parameters were measured using a colorimeter. …

A Seismic Attribute Study To Assess Well Productivity In The Ninilchik Field, Cook Inlet Basin, Alaska, Andrew Sampson

LSU Master's Theses

Coal bed methane which has formed in the Tertiary Kenai Group strata has been produced from the Ninilchik field of Cook Inlet, Alaska since 2001. Ninilchik field is located on the eastern margin of the central Cook Inlet along the Kenai Peninsula. Cook Inlet is a forearc basin and is characterized by northeast trending anticlines with upwards of 10,000 feet of Late Oligocene and younger, non-marine sediments. Highly variable well production within the Oligocene to Miocene Tyonek formation of the Kenai Group has been a source of uncertainty. A series of seismic attributes visualized in Schlumberger's Petrel® software were studied …

The Truth About Lying: The Memorial Effects Of Deliberately Producing Misinformation, Kathleen M. Vieira

LSU Master's Theses

There are different ways of lying and these lies may have different impacts on memory. In this study, participants studied pictures of objects, and later lied and told the truth about these and other objects by describing them or by denying they had seen them. Forty-eight hours later, participants were tested on their source memory. Results revealed that participants had good memory for having falsely described a never-seen object, but poor memory for having falsely denied seeing a studied object. These results suggest that telling certain types of lies may make a person more likely to forget having lied at …

Air Quality At Bus Stops: Empirical Analysis Of Exposure To Particulate Matter At Bus Stop Shelters, Miguel Figliozzi, Adam Moore, Christopher Monsere

Civil and Environmental Engineering Faculty Publications and Presentations

Congested traffic corridors in dense urban areas are key contributors to the degradation of urban air quality. While waiting at bus stops, transit patrons may be exposed to greater amounts of vehicle-based pollution, including particulate matter (PM), because of their proximity to the roadway. Current guidelines for the location and the design of bus stops do not take into account air quality or exposure considerations. This study compared the exposure of transit riders waiting at three-sided bus stop shelters that either faced the roadway traffic or faced away from the roadway traffic. Shelters were instrumented with air quality monitoring equipment, …

Palynostratigraphy Of The Umir Formation, Middle Magdalena Valley Basin (Mmvb) Colombia, Carlos Enrique Santos

LSU Master's Theses

The Late Cretaceous Umir Formation in Middle Magdalena Valley Basin (MMVB) was recently acknowledged as a new target. However, there is little known about the regional distribution of the Umir Formation since it is affected by structural complexity and a major regional unconformity. To improve biosteering of the Umir Formation and reduce exploratory risks, a detailed biostratigraphic analysis of the Umir Formation in the MMVB is presented. Eighty samples from four cores drilled in the Central Eastern MMVB were analyzed for palynological content. These cores represent 976.6 meters of the Middle to Upper Umir Formation. The sediment yielded a good …

Shear Strength Evaluation Of An Erosional Soil System At Fourchon Beach, Jacques Pierre Boudreaux

LSU Master's Theses

South Louisiana is vanishing. Subsidence due to relative sea level rise with erosion of weak wetland soils together produce devastating rates of land loss for this area. It is believed that high rates of erosion are due to weak strength properties of fine-grained sediments in the beaches, marshes, and other wetlands in coastal Louisiana. Wave action is known to initiate the movement of weak coastal soils in a manner that is related to the difference between the shear stresses applied by waves and the critical shear strength of erosional sediments. Direct shear tests were performed on samples obtained from the …

Effect Of Electrical Vehicles On Residential Distribution Systems, Paul Haley

LSU Master's Theses

This thesis focuses on the present state of electrical vehicles (EVs) in the market and the effects that these vehicles could have on residential distribution systems. The current EVs available on the market and the current level of market penetration were investigated. Advantages and disadvantages of EVs from a consumer and governmental perspective were identified. The efficiencies of the whole energy delivery process of electrical vehicles and gasoline vehicles were estimated. Efficiency estimation was used to estimate the impact of EVs on the consumption of fossil fuels and emission of greenhouse gases. Measurement of an EV battery charging cycle and …

Catalytic Oxidative Desulfurization: A Comparison Of Reactors, Andrew Marshall Madrid

LSU Master's Theses

A novel technology, a pulsed oscillating monolith reactor (POMR), was compared to a standard autoclave reactor for oxidative desulfurization (ODS) of a model diesel fuel. Two classes of catalysts, mesoporous Ti-MCM-41 and Pd on carbon, were used for ODS. The oxidants used were O2 and peroxide. The model diesel compound was 75 wt% alkanes, 24 wt% alkylaromatic, 0.95 wt% sulfur heterocycles and 0.05% nitrogen heterocycles. ODS reactions were conducted from 343-423 K and pressures from 1.0-1.3 MPa O2. The only component that was not oxidized was the alkane. The POMR showed promise; there was up to a factor of 20 …

Social Influences On Sculpted Romanesque Corbels In The Eleventh And Twelfth Centuries, Chelsea Buras

LSU Master's Theses

Sculpted corbels of the Romanesque period are often categorized as obscene or grotesque, and frequently dismissed as medieval humor or an individual artist’s imagination. Common themes on corbels include images of debauchery and obscenity, as well as depictions of the effects of sin. These themes are usually communicated through the image of entertainers (acrobats, musicians, and dancers), acts of excess such as overindulgence in alcohol or sexual vice, threatening gestures, monstrous animals, or the human visage transformed by idiocy. As titillating and lowbrow as the images on corbels may seem, they should not be relegated to categories of absurdity or …

Economic And Attitudinal Perspectives Of The Recreational For-Hire Fishing Industry In The U.S. Gulf Of Mexico, Michelle Savolainen

LSU Master's Theses

Socioeconomic and policy information is important to fisheries management in order to assess potential social and economic impacts of proposed fishing regulations. Previous surveys which collect this type of data for the recreational for-hire (RFH) fishing industry in the U.S. Gulf of Mexico were conducted in 1987 and 1997. The third Gulf-wide survey was conducted in 2010 to update the socioeconomic and policy data available on the RFH industry. More specifically, the survey collected captain, vessel, and trip characteristics, firm and trip financial data, targeted species, and opinions on policy issues and hurricane impacts. State license information indicated that 3,315 …

LSU Master's Theses

The purpose of this study was to examine the use and determine the preferred method of social media among 4-H alumni in Louisiana. Based on a review of literature, communicating with youth through social media has become a major trend and necessity, especially among 4-H Youth Development and Cooperative Extension Service professionals. The Zammit Social Media Questionnaire, a 24-item instrument that includes multiple choice, multiple answer, open-ended, ranking, and Likert scale questions, was developed and administered online to 161 Louisiana 4-H alumni who received the 2011 Louisiana 4-H Senior Honor Cord and provided usable e-mails. The final response count was …

Examining Reliability And Validity Of The Roadsign Perception Test, Justin Hull Ory

LSU Master's Theses

The Road Sign Perception Test (RSPT) is a newly developed assessment procedure related to driver advisement, and its psychometric properties have not yet been examined systematically. The present study examined the construct validity and the reliability of RSPT measurements. Cronbach’s α and test-retest reliability statistics were completed, as were correlations reflecting on the test’s construct validity. Results indicated that the RSPT possesses marginal test-retest reliability, adequate internal consistency for duration of stimulus presentation and for specific stimuli, but low for number of signs presented. RSPT performance was significantly correlated with convergent variables measuring aspects of attention, working memory, and spatial …
