Analyzing The Value Of Mixed Use Urban Infill: An Exploratory Analysis On Changes In Property Values And Demographics In Local Initiatives Of Dallas And Fort Worth Texas, Matthew A. Ables

Public Affairs Theses - Archive

Mixed-use infill development has gained national attention as a strategy for revitalization and redevelopment for cities. The strategy is viewed by "Smart Growth" proponents and New Urbanists as a potential solution to sprawling urban forms and a potential cure for many problems associated with auto-dependence. However, this strategy is not new, and it has been debated through different disciplines in relation to its true impacts on communities and cities. Yet, the discussion on infill has centered upon measuring the amount of infill occuring, and the economic impacts of residential infill. This thesis utilizes a descriptive analysis to observe property value …

Weight Modules Of Orthosymplectic Lie Superalgebras, Thomas Lynn Ferguson

Mathematics Dissertations - Archive

A long-standing problem in representation theory is the classification of all simple weight modules of the classical Lie superalgebras. This problem was reduced to the classification of simple bounded highest weight modules. The latter classification has been accomplished for all classical Lie superalgebras except for the orthosymplectic series osp(m|2n) where m = 1, 3, 4, 5, 6. In this thesis, we complete the classification of the simple bounded highest weight modules of osp(1|2n) (i.e., for m = 1). The classification is obtained by developing constraints on primitive vectors in tensor products of bounded (Weyl) and finite-dimensional osp(1|2n)-modules.

Strong patient-provider interaction, medical education through community events and outreach, and stable support systems within family and friends can improve a person's awareness which leads to an increased health literacy level and better well-being. The health literacy level of an individual has been shown to have a direct impact on a person's overall health. Social support and corresponding communication have also been shown as vital. This study used …

Evaluation Of Physico-Mechanical Properties Of Clayey Soils Using Electrical Resistivity Imaging Technique, Golam Kibria

Civil Engineering Dissertations - Archive

Resistivity imaging (RI) is a promising approach to obtaining continuous profile of soil subsurface. This method offers simple technique to identify moisture variation and heterogeneity of the investigated area. However, at present, only qualitative information of subsurface can be obtained using RI. A study on the quantification of geotechnical properties has become important for rigorous use of this method in the evaluation of geohazard potential and construction quality control of landfill liner system. Several studies have been performed to describe electrical resistivity of soil as a function of pore fluid conductivity and surface conductance. However, characterization tests on pore water …

Non-Destructive Sasw Evaluation Of Controlled Low Strength Material As A Pipeline Bedding Material, Rathna Phanindra Mothkuri

Civil Engineering Theses - Archive

Evaluation of stiffness properties of subsurface soil layers provides vital insight into the performance of a geotechnical entity. Stiffness properties can be determined by both field and laboratory tests. Owing to their advantages over laboratory tests, the field tests are often given priority. non-destructive seismic method Spectral Analysis of Surface Waves (SASW) has been implemented in the current research to investigate the stiffness properties of buried materials.The SASW technique works on the principle of wave propagation. The surface wave velocity obtained through the test is used to determine the shear modulus, and thus the stiffness, of the geotechnical entity. In …

Effects Of Climate Change And Perturbation In Biogeochemical Cycles On Oxygen Distribution And Ocean Acidification, Teresa Marie Beaty-Sykes

Earth & Environmental Sciences Dissertations - Archive

Dissolved oxygen (DO) concentration in the ocean is an important component of the marine biogeochemical cycles. In this study a global oceanic carbon cycle model (HAMOCC 2.0) was used to address how oxygen minimum zones (OMZ) respond to changes due to CO₂ radiative forcing. Atmospheric pCO₂ was increased at a rate of 1% annually and the model is stabilized at 2 X, 4 X, 6 X, and 8 X preindustrial pCO₂ levels. With an increase in CO₂ radiative forcing, the OMZ in the Pacific Ocean was controlled largely by changes in particulate organic carbon (POC) export. In contrast, the vertical …

Applications Of Cubical Arrays In The Study Of Finite Semifields, Kelly Casimir Aman

Mathematics Dissertations - Archive

It is well known that any finite semifield, S, can be viewed as an n-dimensional vector space over a finite field or prime order, Fp, and that the multiplication in S defines and can be defined by an n x n x n cubical array of scalars, A. For any element a E S, the matrix, La, corresponding to left multiplication by a can be determined from A. In this paper we show that there exists a unique monic polynomial of minimal degree, f E Fp[x], such that f(a) = 0, and which divides the minimal polynomial of La. Furthermore, …

Development And Analysis Of Low Calcium Flyash Based Geopolymer For Structural Applications, Gaurav Nagalia

Material Science and Engineering Theses - Archive

Geopolymers are an innovative ceramic material composed of long chains and networks of inorganic molecules are being used as an alternative to conventional Portland cement for infrastructure construction, replacement of intersection and localized repairs. Some of the advantages of this material is due to its ultra-fast setting time, rapid strength development and the phenomenal reduction in carbon foot print as compared to Portland cement. However, this material is yet to be commercialized due to the variability in its mechanical strength when using flyash from different sources. In this study aluminosilicate geopolymers with different alkali oxides (feldspars) have been prepared by …

A Hmm-Based Prediction Model For Spatio-Temporal Trajectories, Sakthi Kumaran Shanmuganathan

Computer Science and Engineering Theses - Archive

Spatio-temporal trajectories are time series data that represent movement of an object over the time. Hidden Markov Models (HMM), a variant of Markov Models (MM), were first applied at a large scale to speech recognition but have also been used in time series prediction by analyzing trends in historical time series data. In this research, we propose a storm prediction model using a HMM built from overall storm trajectories derived from raw rainfall data. This HMM is built by assuming the states are associated with clusters created by clustering the locations of each storm from the overall storm trajectories. Then …

Browse all Datasets

The buckwheat Eriogonum corymbosum is widely distributed throughout the southwestern United States, forming a complex of eight varieties. Eriogonum corymbosum var. nilesii is a primarily yellow-flowered taxon reported only from Clark County, Nevada. A previous genetic study by our research group found that variety nilesii is genetically distinct from other E. corymbosum varieties, based on a limited number of populations. Here, we assess genetic variation in 14 newly sampled yellow-flowered populations from southern Nevada, southern Utah, and northern Arizona, and compare them to genetic variation in six populations of previously determined E. corymbosum varieties. Of the new populations, we identified …

Seismic Stratigraphy And Tectonic Evolution Of A Transform Continental Margin, Offshore Sierra Leone, Chinwendu A Elenwa

School of Geography, Earth and Environmental Sciences Theses

The offshore Sierra Leone basin is an exploration frontier area with commercial hydrocarbon potential. The basin is located at the northernmost end of the equatorial Atlantic margin in the South Atlantic; it is bound to the South by the Gulf of Guinea Petroleum province. The Sierra Leone margin has not had the exploration attention like most basins in the equatorial Atlantic, such lack of attention may be explained by the structural complexity of the basin. Despite the recent successful petroleum activities in the basin, very little geological information have been placed in the public domain by the operators. This research …

Department of Exercise Science and Physical Education Scholarship and Creative Works

Objective:Induction of heme oxygenase-1 (HO-1) has been demonstrated to result in chronic weight loss in several rodent models of obesity. However, the specific contribution of the HO metabolite, carbon monoxide (CO) to this response remains unknown. In this study, we determined the effect of chronic low level administration of a specific CO donor on the progression of obesity and its effects on metabolism and adipocyte biology in mice fed a high-fat diet.Design:Experiments were performed on C57BL/6J mice fed a high-fat diet (60%) from 4 weeks until 30 weeks of age. Mice were administered either the CO donor, carbon monoxide releasing …

Inhalation Of Carbon Monoxide Is Ineffective As A Long-Term Therapy To Reduce Obesity In Mice Fed A High Fat Diet, Peter Hosick, Elhaitham K. Ahmed, Monette U. Gousset, Joey P. Granger, David E. Stec

Department of Exercise Science and Physical Education Scholarship and Creative Works

Background: Previous studies have demonstrated that induction of heme oxygenase-1 results in weight loss in several rodent models of obesity. However, the specific role of the heme oxygenase-1 metabolite, carbon monoxide (CO), in this response has yet to be established. We recently reported that chronic treatment with CO releasing molecules results in prevention of weight gain in mice fed a high fat diet. In the present study, we sought to determine the effect of chronic CO inhalation on the development and reversal of high fat diet induced obesity. Results: CO inhalation at both levels initially resulted in a prevention and …

Salt Loading Has A More Deleterious Effect On Flow-Mediated Dilation In Salt-Resistant Men Than Women, S. Lennon-Edwards, M. G. Ramick, Evan Matthews, M. S. Brian, W. B. Farquhar, D. G. Edwards

Department of Exercise Science and Physical Education Scholarship and Creative Works

Background and aims: Dietary sodium loading has been shown to adversely impact endothelial function independently of blood pressure (BP). However, it is unknown whether dietary sodium loading impacts endothelial function differently in men as compared to women. The aim of this study was to test the hypothesis that endothelial-dependent dilation (EDD) would be lower in men as compared to women in response to a high sodium diet. Methods and results: Thirty subjects (14F, 31±2y; 16M, 29±2y) underwent a randomized, crossover, controlled diet study consisting of 7 days of low sodium (LS; 20 mmol/day) and 7 days of high sodium (HS; …

First Principles Computational Modeling Of The Surface Properties Of Uranium Dioxide, Megan Hoover

Physics Theses - Archive

The interaction of uranium dioxide (UO₂) with environmental elements occurs at its exposed surface and a fundamental understanding of this interaction process begins at the atomic scale. In this regard, atomic scale modeling of the properties of clean and adsorbate-covered uranium dioxide (UO₂) surfaces can be used to elucidate UO₂ surface mechanisms such as corrosion and the formation of complex species via environmental gas adsorption. In this thesis, structural and electronic properties of clean and adsorbatecovered low index UO₂ surfaces were modeled using regular and hybrid density functional theory. Specifically, the properties of the clean (111) and (110) surfaces were …

Cutoff Frequencies For Alfven Waves In The Solar Atmosphere, B L Harsha Kalpanie Perera

Physics Dissertations - Archive

Propagation of linear Alfven waves in the isothermal and non-isothermal solaratmosphere is investigated numerically and analytically. It is shown that thetwo wave variables, the velocity and magnetic field perturbations, behave differently and that there is a range of wave frequencies for which the wave behavior changes from propagating to non-propagating. The so-called transition and turning points corresponding to this change are determined analytically, and their locations in the atmosphere are calculated and verified against the numerical results. The transition and turning points are then used to introduce cutoff frequencies, which are different for different wave variables. The main result is …

Purpose: Although risk factors for squamous cell carcinoma of the esophagus and adenocarcinomas of the esophagus (EA), gastric cardia (GC), and other (noncardia) gastric (OG) sites have been identified, little is known about interactions among risk factors. We sought to examine interactions of diet, other lifestyle, and medical factors with risks of subtypes of esophageal and gastric cancers. Methods: We used classification tree analysis to analyze data from a population-based case-control study (1095 cases, 687 controls) conducted in Connecticut, New Jersey, and western Washington State. Results: Frequency of reported gastroesophageal reflux disease symptoms was the most important risk stratification factor …

Response Of Free-Living Nitrogen-Fixing Microorganisms To Land Use Change In The Amazon Rainforest, Babur S. Mirza, C. Potisap, K. Nusslein, B. Bohannan, J. L.M. Rodrigues

Civil and Environmental Engineering Faculty Publications

The Amazon rainforest, the largest equatorial forest in the world, is being cleared for pasture and agricultural use at alarming rates. Tropical deforestation is known to cause alterations in microbial communities at taxonomic and phylogenetic levels, but it is unclear whether microbial functional groups are altered. We asked whether free-living nitrogen-fixing microorganisms (diazotrophs) respond to deforestation in the Amazon rainforest, using analysis of the marker gene nifH. Clone libraries were generated from soil samples collected from a primary forest, a 5-year-old pasture originally converted from primary forest, and a secondary forest established after pasture abandonment. Although diazotroph richness did not …

Background:A strategy to combat infectious diseases, including neglected tropical diseases (NTDs), will depend on the development of reliable epidemiological surveillance methods. To establish a simple and practical seroprevalence detection system, we developed a microsphere-based multiplex immunoassay system and evaluated utility using samples obtained in Kenya.Methods:We developed a microsphere-based immuno-assay system to simultaneously measure the individual levels of plasma antibody (IgG) against 8 antigens derived from 6 pathogens: Entamoeba histolytica (C-IgL), Leishmania donovani (KRP42), Toxoplasma gondii (SAG1), Wuchereria bancrofti (SXP1), HIV (gag, gp120 and gp41), and Vibrio cholerae (cholera toxin). The assay system was validated using appropriate control samples. The assay …

Volatile Phytochemicals As Mosquito Semiochemicals, Vincent O. Nyasembe, Baldwyn Torto

All Peer-Reviewed Publications

Plant biochemical processes result in the release of an array of volatile chemical substances into the environment, some of which are known to play important plant fitness enhancing functions, such as attracting pollinators, thermal tolerance of photosynthesis, and defense against herbivores. Cunningly, phytophagous insects have evolved mechanisms to utilize these volatiles to their own advantage, either to colonize a suitable host for feeding, reproduction and oviposition or avoid an unsuitable one. The volatile compounds involved in plant-insect chemical interactions have been widely exploited in the management of agricultural pests. On the other hand, use of plant volatiles in the management …

The fauna of phytoseiid mites in the state of Mato Grosso do Sul, in midwestern Brazil, is poorly known. The tomato red spider mite, Tetranychus evansi Baker and Pritchard, is an important pest of Solanaceae in several countries, but it is usually found in low densities in Brazil. It has been hypothesized that this is due to the effect of natural enemies. The objective of this study was to identify phytoseiid mites from Mato Grosso do Sul associated with T. evansi, to identify promising biological control agents for T. evansi in Africa. A survey was conducted in October – November …

Resistance To Iris Yellow Spot Virus And Onion Thrips Among Onion Varieties Grown In Kenya, R. K. Birithia, S. Subramanian, J. W. Muthomi, R. D. Narla

All Peer-Reviewed Publications

Iris yellow spot virus (IYSV) vectored by Thrips tabaci threatens profitable onion production in eastern Africa. Host plant resistance is considered to be the first line of defence against insect-transmitted virus diseases. Hence, information on resistance to IYSV and T. tabaci among common onion cultivars in Kenya is crucial for the development of integrated pest management strategies. This study evaluated the resistance to thrips and IYSV among widely grown onion cultivars in Kenya, viz. Red Pinoy, Red Creole, Bombay Red, Green Bunching and Texas Grano, over two growing seasons. Straw-coloured, diamond-shaped necrotic lesions typical of IYSV infection were observed 2 …
