Factors Influencing Agriscience Students Membership Choice in the Alabama FFA Association
(2013-07-15)
The agricultural education youth organization, FFA, has always been considered an integral part of high school agriscience courses. However, there are many students who enroll in agricultural education courses and do not ...
Gasification, Liquefaction and Deoxy-Liquefaction of Switchgrass using Sub- and Supercritical Water
(2013-07-15)
Increased demand in transportation fuels, environmental concerns and depletion of fossil fuel require development of efficient conversion technologies for second-generation biofuels. In this dissertation, sub- and supercritical ...
Biology of Blaptica dubia (Blattodea: Blaberidae)
(2013-07-15)
The Dubia Cockroach, Blaptica dubia Serville, has become a popular food choice among amphibian and reptile enthusiasts. However, there has been little scientific research conducted on this species. My research consists of ...
Does chronic leptin treatment decrease glucagon responsiveness in STZ-induced type 1 diabetic rats?
(2013-07-15)
Central administration of leptin normalizes blood glucose (BG) concentrations in streptozotocin (STZ)-induced diabetic rats. We hypothesize that this is due to a leptin-mediated decrease in glucagon responsiveness.
Male ...
The Effect of Male Plumage Coloration on Parental Effort in Eastern Bluebirds (Sialia sialis)
(2013-07-15)
In iteroparous species, there is tradeoff between current and future reproductive investment. Parents that invest more in current offspring will provide resources that give those offspring better chances of survival and ...
Morphological Analysis in Creative Furniture Design
(2013-07-15)
Design can be defined as a creative process that designers arrange one or more elements and principles in organized for one purpose. The purpose here is to convey a strong message to the reader so the reader can understand ...
Macrophage CXCR7: A Potential New Target for Atherosclerosis
(2013-07-15)
Objective—The discovery of CXCR7 as a new receptor for SDF-1 places many previously described SDF-1 functions attributed to CXCR4 in question, though whether CXCR7 acts as a signaling or “decoy” receptor has been in debate. ...
Evaluation of Toxicity Levels and Cytotoxicity Mechanisms of Corexit 9500
(2013-07-15)
The 2010 British Petroleum (BP) oil spill in the Gulf of Mexico has raised many ecological and health concerns. BP predominately used Corexit9500A to disperse crude oil in the Gulf of Mexico to prevent shoreline contamination. ...
Multivariate Characterization, Modeling, and Design of Chemical Products in Property Cluster Space
(2013-07-15)
The focus of this dissertation is on the development of in silico approaches for the logical and systematic solution of chemical product design problems. The application of multivariate characterization, modeling, and ...
Passive microfluidic methods for sampling hormone secretions from primary islets and adipocytes
(2013-07-11)
We have developed an 8-channel passive microfluidic device that is capable of sampling both primary islet and adipocytes. Although there are microdevices already published in the literature; they require bulky external ...
Fracture Behavior of Particulate Polymer Composites (PPCs) and Interpenetrating Polymer Networks (IPNs): Study of Filler Size, Filler Stiffness and Loading Rate Effects
(2013-07-11)
Particulate Polymer Composites (PPCs) generally consist of nano- or micro-fillers of various sizes and shapes randomly dispersed in a polymer matrix. Introduction of second phase fillers of different stiffness and alteration ...
A Study of the Effect of Various Material Combinations on the Bolted Contacts of Busbars
(2013-07-11)
The reliability of bolted joints is a concern for high-powered devices as the generated heat and thermal expansion could loosen the connections over many actuation cycles. There currently appears to be relatively little ...
Counterproductive behavior's impact on external stakeholders' decisions: Does "I'm sorry" remedy deviance?
(2013-07-11)
Counterproductive work behaviors (CWBs) are acts that hinder or are intended to hinder the objectives of organizations or their members. To date, several studies have examined the organizational and interpersonal consequences ...
Examining the Career Thoughts of Veterans Enrolled in College
(2013-07-11)
Veterans returning from the Operation Enduring Freedom (OEF) and Operation Iraqi
Freedom (OIF) conflicts are enrolling in colleges and universities at the highest number since
post World War II (Cook & Kim, 2009). However, ...
Water Balance Analysis Using WARMF in Support of an EFDC Hydrodynamic Model
(2013-07-11)
An Environmental Fluid Dynamics Code (EFDC) model was previously developed for Bankhead Reservoir, located in northwest Alabama. The EFDC model inaccurately predicted water surface elevations in the reservoir, due to sources ...
Three-Dimensional Modeling of Elasto-Plastic Sinusoidal Contact under Time Dependent Deformation Including Both Stress Relaxation and Creep Analysis
(2013-07-11)
Computational modeling of contact between rough surfaces has attracted a great deal of attention due to the developing technological needs of industry. Most of the early models of rough surface contacts assumed a cylindrical ...
Evaluation of the accessory sex glands of the bull for the presence of Tritrichomonas foetus
(2013-07-11)
A bull infected with the venereal protozoan Tritrichomonas foetus can become a chronic carrier, remaining infected for life. It has been theorized that as a bull ages he develops deep folds or crypts in the epithelium ...
The effect of collimation on image quality and radiation safety in digital radiography of small animals
(2013-07-11)
