Multiscale Structure-Function Relations Of A Tendon, Lakiesha Nicole Williams
Multiscale Structure-Function Relations Of A Tendon, Lakiesha Nicole Williams
Theses and Dissertations
In 1998, the United States National Committee on Biomechanics (USNCB) established an evolving discipline called Functional Tissue Engineering (FTE). In establishing this discipline, the goals of the USNCB were to advance FTE by increasing awareness among tissue engineers about the importance of restoring function when engineering tissue constructs. Another goal was to encourage tissue engineers to incorporate these functional criteria in the design, manufacturing and optimization of tissue engineered constructs. Based on this motivation, an investigation of the structure and mechanical properties of the rabbit patellar tendon will be executed, with the ultimate goal of creating a multiscale soft tissue …
Single-Step Treatment Of 2,4-Dinitrotoluene Via Zero-Valent Metal Reduction And Chemical Oxidation, J. Mathew Thomas
Single-Step Treatment Of 2,4-Dinitrotoluene Via Zero-Valent Metal Reduction And Chemical Oxidation, J. Mathew Thomas
Theses and Dissertations
Many nitroaromatic compounds (NACs) are considered toxic and potential carcinogens. The purpose of this study was to develop an integrated reductive/oxidative process for treating NAC contaminated waters. The process consists of the combination of zero-valent manganese or iron and a hydroxyl radical based treatment technique. Corrosion promoters were added to the contaminated water to minimize passivation of the metallic species. Water contaminated with 2,4-dinitrotoluen (DNT) was treated with the integrated process using a recirculating batch reactor. It was demonstrated that addition of corrosion promoters to the contaminated water enhanced the rate of reaction of 2,4-DNT with zero-valent iron or manganese. …

Bacterial Source Tracking Of A Watershed Impacted By Cattle Pastures, Celina Phelps
Bacterial Source Tracking Of A Watershed Impacted By Cattle Pastures, Celina Phelps
Theses and Dissertations
Pathogenic microorganisms introduced by cattle may be transported to distant locations via watershed runoff. Escherichia coli, Enterococcus spp., and Streptococcus spp. are a few species present in runoff from land impacted by humans, cattle, and wildlife. Initial data reveals that E. coli concentrations in water are greater in areas impacted by cattle than by humans. And, wildlife contributes greater concentration fluctuations than either humans or cattle. When cattle are removed from a pasture, the bacterial concentrations rapidly decrease; however, slight variations in cattle herd size do not appear to significantly influence these counts. Amplified fragment length polymorphisms (AFLP) and repeated-sequence …
Clustering Multiple Contextually Related Heterogeneous Datasets, Mahmood Hossain
Clustering Multiple Contextually Related Heterogeneous Datasets, Mahmood Hossain
Theses and Dissertations
Traditional clustering is typically based on a single feature set. In some domains, several feature sets may be available to represent the same objects, but it may not be easy to compute a useful and effective integrated feature set. We hypothesize that clustering individual datasets and then combining them using a suitable ensemble algorithm will yield better quality clusters compared to the individual clustering or clustering based on an integrated feature set. We present two classes of algorithms to address the problem of combining the results of clustering obtained from multiple related datasets where the datasets represent identical or overlapping …

InlA expression was not detected in silver stained SDS gels but was detected in Western blotting images. Internalin A was only detected in protein extracts of L. monocytogenes 19111 and 7644 with band intensities of 50.1 and 2.5 pixels, respectively. Greater InlA expression was correlated with higher attachment strength in L. monocytogenes 19111. Listeria monocytogenes 19115 did not express InlA but it had a stronger attachment …
The Chemical And Mechanical Effects Of Binding Chitosan To Implant Quality Titanium, Holly Joy Martin
The Chemical And Mechanical Effects Of Binding Chitosan To Implant Quality Titanium, Holly Joy Martin
Theses and Dissertations
Biomedical implants are commonly made from commercially pure titanium and other metal alloys, which are chosen for their strength and density. To improve the stability and promote bone cell growth into the implant, efforts to bond coatings to metal have been extensively studied. Many coatings used are considered bioactive, which promote the adhesion and growth of the bone cells surrounding the implant [A.1]. Of these, the most commonly investigated coating is a ceramic called hydroxyapatite, which is brittle, leading to flaking and inadequate bone cell growth [A.2]. Alternate bioactive coatings are being examined, including chitosan, the deacetylated form of chitin. …
Effects Of Vasoactive Agents On The Mechanical Properties Of Aortic Heart Valve Leaflets, Rebecca Lynn Pounders Mathis
Effects Of Vasoactive Agents On The Mechanical Properties Of Aortic Heart Valve Leaflets, Rebecca Lynn Pounders Mathis
Theses and Dissertations
Heart valve disease is currently one of the leading forms of heart disease. Current literature has shown that endothelin I, angiotension II and 5-HT are vasoactive agents which cause concentration dependent contractions in aortic valve leaflet tissue. This study tested the mechanical properties of leaflets cut in the radial direction after they were exposed to the agents at varied concentrations or for 0.5, 6 or 24 hours. The elastic modulus, ultimate tensile strength and the yield strength were calculated. In the time trials the elastic modulus and the ultimate tensile strength both showed a significant increase at 24-hours. However, there …
Heat Transfer And Friction In Helically-Finned Tubes Using Artificial Neural Networks, Gregory J. Zdaniuk
Heat Transfer And Friction In Helically-Finned Tubes Using Artificial Neural Networks, Gregory J. Zdaniuk
Theses and Dissertations
The last few decades have seen a significant development of complex heat transfer enhancement geometries such as a helicallyinned tube. The arising problem is that as the fins become more complex, so does the prediction of their performance. In addition to discussing existing prediction tools, this dissertation demonstrates the successful use of artificial neural networks as a correlating method for experimentally- measured heat transfer and friction data of helicallyinned tubes.

Impact Of Foliar Fungicides On Yield And Net Returns In Soybeans, Benjamin L. Spinks
Theses and Dissertations
Field studies were conducted in 2003, 2004, and 2005 in the Mississippi delta at 12 locations across common production practices to evaluate the impact of 12 single applications of fungicides at the R3 and R5 growth stage on soybean yield, seed quality, and net returns. Averaged across locations, azoxystrobin alone and mixed with other fungicides increased yields 161 to 343 kg/ha compared to the nontreated control. Fungicide applications made at R3-R4 were more efficacious and resulted in larger yield increases than applications made at R5-R6. Plots treated at the R3-R4 growth stage with 0.11kg ai/ha azoxystrobin alone or in combination …
Functional Role Of Recombinant Cysteine Protease On Spodoptera Frugiperda Peritrophic Matrix, Srinidi Mohan
Functional Role Of Recombinant Cysteine Protease On Spodoptera Frugiperda Peritrophic Matrix, Srinidi Mohan
Theses and Dissertations
Fall armyworm larvae (FAW), which are serious pests in the southern United States, show retarded growth when they feed on insect-resistant maize inbreds Mp704 and Mp708. These maize genotypes are not only resistant to FAW, but to a number of other lepidopteran pests. In these genotypes, a unique, extracellular, 33-KDa cysteine protease (Mir1-CP) rapidly accumulates in the whorl in response to insect feeding. Initial morphological studies on larvae feeding on resistant maize plants over-expressing the cysteine protease showed severe damage in insect?s first line of defense, the peritrophic matrix (PM). But it is not known whether the cysteine protease has …

Effectiveness Of Postharvest Sanitation Treatments On Microbial Load Of Blueberries, Wei-Chun Chen
Theses and Dissertations
The purpose of this study was to determine the quality and microbial load of blueberries at different maturity stages, to develop the effective microbial recovery method and to compare sanitation postharvest treatments on microbial counts of blueberries. The soluble solids and the sugar to acid ratio increased, while pH and TA decreased with maturity. Ripe berries had lower yeast and mold counts (YMC) at other maturity stages, but there were no differences on aerobic plate counts (APC). The medium pH was lower for stomaching and blending than hand massaged samples. This leads to higher recovery of microorganisms by massaging. Sodium …

Angiotensin Ii Mediated Regulation Of Signal Transduction In Metabolic Syndrome And Cancer, Ravindra Bharatrao Kolhe
Angiotensin Ii Mediated Regulation Of Signal Transduction In Metabolic Syndrome And Cancer, Ravindra Bharatrao Kolhe
Theses and Dissertations
Patients suffering from hypertension often develop non-Insulin dependent diabetes mellitus (NIDDM), a condition caused by Insulin resistance. Though these patients have normal Insulin receptor (IR) and high levels of Insulin in blood, they fail to have IR-mediated signaling essential for glucose uptake and availability. NIDDM usually begins as insulin resistance, a condition in which Insulin Receptor (IR)-mediated signaling that leads to glucose uptake and glucose availability to cells is inhibited even in the presence of high levels of Insulin in blood. Mechanisms for the development of this Insulin resistance in patients suffering from hypertension are unclear. Angiotensin II (Ang II) …
