Regulation Of Adipose Tissue Metabolism By Nfkb P65 In Transgenic Mice, Tianyi Tang Jan 2009

Regulation Of Adipose Tissue Metabolism By Nfkb P65 In Transgenic Mice, Tianyi Tang

LSU Master's Theses

Inflammation has been widely reported to regulate adipocyte functions in adipose tissue. Our early study suggests that NFkB signaling pathway is activated by inflammation and involved in inhibition of insulin sensitivity in adipocytes. NFkB was found to inhibit PPARg function through several possible mechanisms in 3T3-L1 adipocytes. To test this possibility in vivo, we increased the NFkB activity in adipocytes in transgenic mice by expression of NFkB p65 subunit under the aP2 gene promoter. The phenotype study shows that the food intake, physical activity and development are similar in the two groups. The reproductivity was not different in the two …

Investigation Into The Hydrothermal Treatment Of Sugarcane Bagasse Under Near- And Supercritical Conditions, John E. White Jan 2009

Investigation Into The Hydrothermal Treatment Of Sugarcane Bagasse Under Near- And Supercritical Conditions, John E. White

LSU Doctoral Dissertations

Processing biomass in near- and supercritical water has garnered increasing attention because of its ability to accept a variety of wet feedstocks, energy efficiency, and ability to regulate the solubility and separation of components. Very few studies of biomass hydrothermal conversion provide a comprehensive evaluation of multiple process parameters and various additives and their effects on a single product phase. This research examined the influence of temperature, residence time, biomass concentration, and particle size on volatiles production from the hydrothermal conversion of sugarcane bagasse. Temperature had the greatest impact on volatile yields with the largest increase (23 wt %) occurring …

The Effect Of Interactive Homework On Dibels Performance, Shelley M. Scott Jan 2009

The Effect Of Interactive Homework On Dibels Performance, Shelley M. Scott

LSU Master's Theses

Homework is a common practice in most kindergarten classrooms. There are varying opinions on the purpose of homework, the frequency in which homework should be given, the duration of time kindergarten-aged students should spend on homework, and how the use of homework impacts student performance. The DIBELS (Good & Kamanski, 2003) is an assessment tool that measures student performance on early literacy skills and identifies students who are at-risk for failure to read. The proposed study will incorporate recommendations for creating developmentally appropriate homework that addresses skill deficiencies identified by the DIBELS to determine the impact of homework on DIBELS …

Motivating Middle School Students To Be Physically Active: The Role Of Supportive Environments, Tao Zhang Jan 2009

Motivating Middle School Students To Be Physically Active: The Role Of Supportive Environments, Tao Zhang

LSU Doctoral Dissertations

It is clearly documented that promoting regular physical activity participation at young ages increases the likelihood that school-aged students will lead active lifestyles as adults. Unfortunately, more than a third of school-aged students do not engage in sufficient amounts of physical activity necessary to produce significant health benefits (USDHHS, 2000, 2008). Public health officials and physical educators highlight the importance of promoting motivation for physical activity by creating a supportive physical activity environment that should positively influence students’ choices to be physically active. The major objective of this dissertation was to explore the roles of supportive social environments and physical …

Population Characteristics Of A White-Tailed Deer Herd In A Bottomland Hardwood Forest Of South-Central Louisiana, Justin W. Thayer Jan 2009

Population Characteristics Of A White-Tailed Deer Herd In A Bottomland Hardwood Forest Of South-Central Louisiana, Justin W. Thayer

LSU Master's Theses

White-tailed deer are an important economic and recreational resource in Louisiana. A basic understanding of population dynamics is essential to ensure sound management, but baseline information in Louisiana is lacking. Likewise, the notion of Quality Deer Management (QDM) continues to gain momentum in Louisiana. Our objectives were to evaluate space use, survival, and mortality for a deer herd managed under a QDM regime in south Louisiana. We captured 65 deer in West Baton Rouge and Iberville Parishes during 2007 and 2008, radio-marked 37 males and 11 females, and ear-marked an additional 10 males and 7 females.

Project-Based High School Geometry, Danica Le'trice Robinson Jan 2009

Project-Based High School Geometry, Danica Le'trice Robinson

LSU Master's Theses

Project-based learning (PBL) is an instructional strategy that allows students the autonomy to learn, explore and investigate throughout the learning process by means of projects. Many educators have seen the need for such a strategy in the classroom as a remedy for motivating students, showing relevance of student’s education to everyday life, preparing students for college and the work force, and the dire need for students to develop critical thinking skills to encourage future success. In my thesis I will define project-based learning, discuss its characteristics, compare PBL to traditional teaching methods and reflect on my experiences with project-based learning …

Spot-Carp Symposium And Collective Dissent: A Cross-National And Sub-National Analysis, Swetasree Ghosh Roy Jan 2009

Spot-Carp Symposium And Collective Dissent: A Cross-National And Sub-National Analysis, Swetasree Ghosh Roy

LSU Doctoral Dissertations

The main analytical concern of this dissertation is to develop theoretical and methodological tool to improve our understanding of collective violence, like civil wars, riots, etc. There are essentially two major problems in the existing literature: compartmentalization of focus on structure or action and inadequate systematic analysis of bridging this gap. This dissertation is an attempt to address these deficiencies in the literature. Using the opportunity-willingness framework of interstate conflicts, I propose a mid-range theoretical approach to the structure-action problem. I argue that structural and political opportunities lead to more collective action if willingness is present in the form of …

Studies Of States And State Transitions In Low Mass X-Ray Binaries, Charles Bradley Jan 2009

Studies Of States And State Transitions In Low Mass X-Ray Binaries, Charles Bradley

LSU Doctoral Dissertations

We investigate the model of a disk/coronal accretion flow into a black hole. We build a numerical code to ascertain whether the inner regions of an accretion disk in X-ray binaries can transform from a cool standard disk to an advection-dominated flow through the known properties of Coulomb interaction in a two-temperature plasma, taking into account viscous heating, standard radiation processes, and thermal conduction. A hot, diffuse corona covering the whole disk is powered by accretion, but it exchanges energy with the underlying cool disk through radiative interactions and conduction. If the accretion rate is low enough, at some intermediate …

Environmental Influences On The Mobility And Speciation Of Arsenic In The Geothermal Waters Of El Tatio Geyser Field, Chile, Lindsey R. Johnson Jan 2009

Environmental Influences On The Mobility And Speciation Of Arsenic In The Geothermal Waters Of El Tatio Geyser Field, Chile, Lindsey R. Johnson

LSU Master's Theses

El Tatio geyser field, northern Chile, impacts regional water quality, policy, and agricultural commerce due to the geothermal waters containing high concentrations of naturally-occurring arsenic (As). In the circumneutral pH, non-sulfidic thermal waters at El Tatio, dissolved arsenite [As(III)] dominates geyser discharge water upstream, but dissolved arsenate [As(V)] dominates downstream. Microbial mats and sediments were analyzed for changes in As speciation using X-ray spectroscopy methods, such as XANES and EXAFS at both the As and Fe K-edges, combined with ATR-FTIR spectroscopy and molecular genetics, to understand As cycling. The sediments and microbial mats were dominated by As(V) speciated as both …

Size Controlled Metal Oxide Nanoparticles:Synthesis, Characterization, And Application To Catalysis, Hongyi Wu Jan 2009

Size Controlled Metal Oxide Nanoparticles:Synthesis, Characterization, And Application To Catalysis, Hongyi Wu

LSU Doctoral Dissertations

The research in this dissertation focuses on the synthesis of size-controlled metal oxide nanoclusters (< 10 nm) on amorphous silica and their catalytic performance in thermal degradation of chlorinated benzenes with regard to the cluster size effect. Furthermore, with the concern that metal can condense as the nano-size nuclei core for particle growth in combustion process, a flow reactor was built to investigate the effect of metal oxide nanoparticles on the formation of soot in fuel-rich combustion. The synthesis of copper oxide nanoclusters was carried by calcination of silica impregnated with dendrimer-metal complexes. The 4th generation poly(propylene imine) dendrimer DAB-Am32 was used in this template-based method. The sizes of copper oxide nanoclusters were exquisitely controlled in the range of 1-5 nm with narrow size distribution by changing the stoichiometric ratio of metal ion to the terminal primary amines of dendrimer, the equivalent metal oxide loading on surface, and the impregnation procedure. XANES and XPS studies revealed that CuO was the dominant component of copper oxide nanoclusters. This method was also experimentally proven to be valid in the preparation of other metal oxide nanoparticles, e.g., Ni and Fe, and with other oxide substrates, e.g., titanium oxide. Chlorinated benzenes were selected as the model compound for studying the activity of metal (Cu and Fe) oxide catalysts with regard to their cluster sizes. Compared to the surrogate of coarse metal oxide samples, which was prepared by incipient wetness method, their nanosize analogues showed superior catalytic activity on the conversion of chlorinated benzenes under both pyrolytic and oxidative thermal condition. Furthermore, such catalytic size effect was also observed on the selectivity of products yields. Sooting combustion was performed using a two-zone flow reactor with precise control on experimental parameters. Gas suspended metal oxide nanoparticles were generated by burning off the organic backbone of the dendrimer-metal complexes in zone 1 and immediately transferred to zone 2, where the hydrocarbon combustion occurred. TEM results of the particulate sample collected at the outlet of reactor indicated that metal oxide nanoparticles promoted soot formation. GC/MS analysis of the extracted organic materials from soot samples suggested the formation of PAH was also promoted by metal addition as well.

Protecting Private Property With Constitutional Judicial Review: A Social Welfare Approach, Daniel H. Cole, Peter Z. Grossman Jan 2009

Protecting Private Property With Constitutional Judicial Review: A Social Welfare Approach, Daniel H. Cole, Peter Z. Grossman

Articles by Maurer Faculty

This article uses a social welfare approach to determine if and when the institution of constitutional judicial review of property regulation and expropriation is efficient. A model is proposed in which property rights protection is a component of social costs. Constitutional judicial review is assumed to either add to or subtract on net from those costs, affecting social welfare generally. It will be shown that under realistic conditions, reflected in real instances, that constitutional judicial review might not enhance economic efficiency or overall social welfare. We show that the efficiency of constitutional judicial review is likely to vary within the …

The Influence Of Alcohol Advertising On Associative Memory And Consideration Sets, James Charles Smith Jan 2009

The Influence Of Alcohol Advertising On Associative Memory And Consideration Sets, James Charles Smith

LSU Doctoral Dissertations

Survey studies suggest that alcohol advertising influences attitudes and beliefs that promote alcohol use. Strategies from memory research and marketing were used to test the influence of beer advertising found in popular magazines. Effects on preference for alcohol and memory associations between alcohol and the positive outcomes of drinking were measured. One hundred eighty undergraduate women and men viewed 5 ads. A 2 x 2 + 1 (control group) factorial design simultaneously varied ad type (arousing or sedating messages) with processing type (selective attention or elaborative processing). Preferences for alcohol and memory associations did not differ between the control group …
