Vitamin D And Malignant Melanoma Outcomes, Jenna L. Green
Vitamin D And Malignant Melanoma Outcomes, Jenna L. Green
Theses and Dissertations
Ultraviolet exposure from sunlight and other sources is the major risk factor for the development of malignant melanoma of the skin. Exposure to sunlight is also the main pathway the human body obtains vitamin D. Cell proliferation, differentiation and inhibition is mediated in part by vitamin D, leading researchers to suspect vitamin D has a protective role in various cancers, including melanoma. The purpose of the project was to review the current available literature focusing on the relationship between vitamin D levels and melanoma outcomes. The review of the literature was designed to address the clinical question: What is the …
Assessment Of Pain In The Older Adult With Dementia, Helen Laferriere
Assessment Of Pain In The Older Adult With Dementia, Helen Laferriere
Theses and Dissertations
Pain is common in the older adult as they continue to age regardless of their cognitive ability. Whether the older adult resides in the community, in a nursing facility or is hospitalized, pain is prevalent in this population. The assessment and management of pain in the older adult with cognitive impairment is a challenge for those in healthcare. Based on the severity of the dementia, the older adult may not be able to verbalize or describe their pain. Therefore, it is vital that healthcare providers are able to identify pain in this population. Observational assessment scales, such as the Abbey …
Developing A Remote Sensing Algorithm For Deriving Soil Moisture From Spectral Reflectance, Santosh Rijal
Developing A Remote Sensing Algorithm For Deriving Soil Moisture From Spectral Reflectance, Santosh Rijal
Theses and Dissertations
Wet weather cycle since 1993 has brought ground water level closer to the surface of the soil in many areas in the Red River Valley (RRV) of the North basin. Many farmers have to delay spring plantation or autumn harvest due to excessive moisture in', their farmland. In such case, it becomes increasingly important to have timely and accurate information on the soil moisture conditions. Conventional soil moisture measurement techniques are point-based that results in poor spatial representation of soil moisture. Remote sensing techniques offer many potential advantages over traditional means such as repetitive coverage and areal representation. The objective …
Communication Barriers Between Providers And Parents Of Adhd Adolescent Patients Who Use Complementary And Alternative Medicine, Angela Sietz
Theses and Dissertations
There is increased use of complementary and alternative medicine (CAM) to treat attention deficit hyperactivity disorder (ADHD) symptoms in children and adolescents. Some of the most common types of CAM used in ADHD include: modified diet, vitamins/and or minerals, dietary supplements, aromatherapy and chiropractic care. Many parents/patients do not share their use of CAM with their provider. This inadequate communication between parents and health care providers can be dangerous. This paper addresses the prevalence of ADHD, the types of CAM being used and discusses evidence in support of these therapies. Communication between patients and providers regarding the use of CAM …
The Effectiveness Of Using Non-Pharmacological Interventions In Managing Behavioral And Psychological Symptoms Of Dementia (Bpsd) In Long Term Care Facilities, Sandra J. Holmgren
The Effectiveness Of Using Non-Pharmacological Interventions In Managing Behavioral And Psychological Symptoms Of Dementia (Bpsd) In Long Term Care Facilities, Sandra J. Holmgren
Theses and Dissertations
Neuropsychiatric symptoms such as aggression, agitation, anxiety, mood disorders, and psychosis are frequently associated with the diagnosis of dementia (Schneder, Dagennan, & lnsel, 2005; Wand et al., 2005; Zee & Burkett, 2008). These tenns have been grouped together under the term 'behavioral and psychological symptoms of dementia' (BPSD) by the International Psychogeriatiic Association (Douglas, James, & Ballard, 2004). Neuropsychiatric symptoms are often reasons for institutionalization in nursing homes due to increased burden and stress on the caregiver (Douglas, James & Clive, 2004; Murman et al, 2002). As the elderly population continues to grow, dementia and its related symptoms will remain …

In this paper, replacing complete or partly of growth mediums with secondarily wastewater was studied. Lipid content of Neochloris oleoabundans grown in a 0.3 X SE medium and autoclaved secondarily treated wastewater mixture was 22.27 % (w/w). The maximum biomass concentration of N. oleoabundans grown in wastewater with no additional nutrients was 0.636 g/L with 33% (w/w) glucose. Two culture lines, MA, and NA were isolated within our laboratory and could grow in secondarily treated wastewater with no additional nutrients. The maximum biomass concentration of MA in batch culture was 0.860 g/L and the sum of glucose and xylose was …
A Minimum Spanning Tree Based Clustering Algorithm For High Throughput Biological Data, Harun Pirim
A Minimum Spanning Tree Based Clustering Algorithm For High Throughput Biological Data, Harun Pirim
Theses and Dissertations
A new minimum spanning tree (MST) based heuristic for clustering biological data is proposed. The heuristic uses MSTs to generate initial solutions and applies a local search to improve the solutions. Local search transfers the nodes to the clusters with which they have the most connections, if this transfer improves the objective function value. A new objective function is defined and used in the heuristic. The objective function considers both tightness and separation of the clusters. Tightness is obtained by minimizing the maximum diameter among all clusters. Separation is obtained by minimizing the maximum number of connections of a gene …
Linear Dynamic Model For Continuous Speech Recognition, Tao Ma
Linear Dynamic Model For Continuous Speech Recognition, Tao Ma
Theses and Dissertations
In the past decades, statistics-based hidden Markov models (HMMs) have become the predominant approach to speech recognition. Under this framework, the speech signal is modeled as a piecewise stationary signal (typically over an interval of 10 milliseconds). Speech features are assumed to be temporally uncorrelated. While these simplifications have enabled tremendous advances in speech processing systems, for the past several years progress on the core statistical models has stagnated. Since machine performance still significantly lags human performance, especially in noisy environments, researchers have been looking beyond the traditional HMM approach. Recent theoretical and experimental studies suggest that exploiting frame-torame correlations …
Dynamics Of Classical Particles And Quantum Spin Systems, Marta Licelis Guerra
Dynamics Of Classical Particles And Quantum Spin Systems, Marta Licelis Guerra
Theses and Dissertations
This dissertation is divided in two parts. In the first part, we study the dynamics of a classical particle system. We calculate the efficiency of a rejectionree dynamic Monte Carlo method in the limit of low temperatures and/or high densities for d-dimensional off-lattice homogeneous particles interacting through a repulsive power-law potential r−p. Theoretically we find the algorithmic efficiency is asymptotically proportional to ρ (p+2)/2 T-d/2 with the particle density ρ and the temperature T. Dynamic Monte Carlo simulations are performed in 1-, 2- and 3-dimensional systems with different powers p, and the results agree with the theoretical predictions. In the …
Analysis Of Conservation Practices In The Blackland Prairie Region Of Mississippi And Construction Of A Predictor For Locating New Sites For Conservation Efforts, Steven Cameron Hughes
Analysis Of Conservation Practices In The Blackland Prairie Region Of Mississippi And Construction Of A Predictor For Locating New Sites For Conservation Efforts, Steven Cameron Hughes
Theses and Dissertations
Mississippi’s Blackland Prairie has been reduced below 10% of pre-Columbian extent, with few conservation practices in place. To determine efficacy of current restoration practices, plant species at remnant sites were compared with those at restoration sites. Analyses using multivariate statistical approaches revealed no generalizable patterns among four available remnants versus two available restoration sites. Thus, the aim of this project shifted to evaluating methods of identifying Blackland Prairie remnants or potential restoration sites. Location data for Blackland Prairie plant species and potentially informative environmental variables were used to develop geographic information system (GIS)-based habitat models. The best models were selected …
Wildlife Habitat Quality In Southern Mississippi 8 Years After Intensive Pine Plantation Establishment, Tamara Nicole Campbell
Wildlife Habitat Quality In Southern Mississippi 8 Years After Intensive Pine Plantation Establishment, Tamara Nicole Campbell
Theses and Dissertations
I evaluated effects of 5 pine plantation establishment regimes 6 – 8 years postestablishment on loblolly pine (Pinus taeda) growth, vegetation characteristics, nutritional carrying capacity for white-tailed deer, and breeding birds in the Lower Coastal Plain of Mississippi. Treatments combined mechanical site preparation (MSP), chemical site preparation (CSP), and herbaceous weed control (HWC) designed to represent a range of operational intensities. Chemical SP provided greater long-term control of woody competition than MSP, but did not provide significant pine growth advantage. Vegetation richness, diversity, and structure were best maintained with MSP and year 1 banded HWC. Canopy cover appears to be …

Aquatic Invertebrate Biomass And Community Composition In Greentree Reservoirs And Naturally Flooded Forests In The Mississippi Alluvial Valley And Interior Flatwoods, Justyn Richard Foth
Theses and Dissertations
The Mississippi Alluvial Valley (MAV) contained vast bottomland hardwood forests into the 20th century. Humans cleared forests, and altered hydrology, yet the MAV remains important for North American waterfowl and other wildlife. To estimate standing crops of aquatic invertebrates as food in hardwood bottomlands for wintering waterfowl, I quantified dry mass of invertebrates in naturally flooded forests (NFFs) and greentree reservoirs (GTRs) during winters 2008–2010. The MAV had greater invertebrate mass in NFFs (x̄ = 18.39 kg/ha; SE = 2.815 [CV = 15.3%]) than GTRs (x̄ = 5.16; SE = 0.492 [CV = 9.5%]), compared with lesser masses in Mississippi …
Agricultural Conservation Buffers For Breeding Grassland Birds In Eastern Mississippi, Heidi Lynn Adams
Agricultural Conservation Buffers For Breeding Grassland Birds In Eastern Mississippi, Heidi Lynn Adams
Theses and Dissertations
Periodic disturbance in CP33 habitat buffers is required to maintain early-successional plant communities for grassland birds. However, effects of disturbance on habitat suitability and nesting success of grassland birds are unknown. Furthermore, the grassland bird community and reproductive performance in CP33 habitat buffers may be influenced by the landscape context (e.g., edge habitat, surrounding land cover). My objectives for this study were to determine how periodic disturbance and the agricultural landscape mosaic influence the breeding grassland bird community in buffers, and how these same factors influence grassland bird nesting success and density in buffers. Data collected during line-transect surveys conducted …

Assessment And Prediction Of Streambank Erosion Rates In A Southeastern Plains Ecoregion Watershed In Mississippi, John Jairo Ramirez Avila
Theses and Dissertations
The Town Creek Watershed (TCW) is a representative area of the Tombigbee River Basin and the Southeastern Plains Ecoregion in Mississippi. The principal channel and four main tributaries have been included for several years within the MS Section 303(d) list of waterbodies biologically impaired due to sediment. The TMDL developed for TCW recommended that streams located near cultivated lands, road crossings and construction activities are a priority for streambank and riparian buffer zone restoration and sediment loads reduction. Development of remedial measures and future BMPs within TCW for reducing water quality impairment and downstream dredging costs requires identification of sediment …
Stand Level Compatible Diameter Distribution Models For Red Oak-Sweetgum Complexes On Minor Stream Bottoms In The South, Wesley James Howard
Stand Level Compatible Diameter Distribution Models For Red Oak-Sweetgum Complexes On Minor Stream Bottoms In The South, Wesley James Howard
Theses and Dissertations
Southern bottomland hardwood forests lack effective growth and yield predictive models primarily due to the complexity of the ecosystems. These models are important tools for relative comparison of management schemes and making sound management decisions to obtain optimal future yields. Starting in 1982, 150 red oak-sweetgum bottomland hardwood growth and yield plots were established in northern and central parts of Mississippi. These plots were remeasured in 1988, 1992, 1993, 2005, 2006, and 2007 along with the addition of new plots. A diameter distribution model was developed from stand level component equations constructed in a previous study (Iles 2008; Schultz et …

Theses and Dissertations
Little research has been done to validate the biomechanical principles of tibial tuberosity advancement (TTA) throughout stance. The present study evaluates the effects of TTA on kinematics of the cranial cruciate (CrCL) deficient stifle during early, middle, and late stance. Cadaveric pelvic limbs were evaluated for the effects of TTA on kinematics under a load equivalent to 30% bodyweight and under the following treatment conditions: intact CrCL, CrCL deficient, TTA-treated, and TTA treated + meniscal release. Electromagnetic tracking sensors were used to determine tibial subluxation and rotation relative to the femur. Transection of the CrCL resulted in significant cranial tibial …
Empirical Studies Of Arundinaria Species For Restoration Purposes, Mary Catherine Mills
Empirical Studies Of Arundinaria Species For Restoration Purposes, Mary Catherine Mills
Theses and Dissertations
The research in this thesis concentrates on investigation of the ecology of Arundinaria species for restoration purposes. Arundinaria species are key components in the canebrake ecosystem that was once prominent in the southeastern United States. Arundinaria still occurs as an understory component of bottomland hardwood forests, but with intense agricultural development and urbanization over the past 200 years, canebrakes are now a critically endangered ecosystem with greater than 98% loss. Specifically the thesis addresses the establishment of Arundinaria with other plant species and site preparation techniques. This study indicated that A. gigantea planted into plots dominated by non-native plants benefited …

Theses and Dissertations
A point intercept survey was conducted from 2005 to 2010 on the Ross Barnett Reservoir near Jackson, MS to calculate the frequency of occurrence of all aquatic plant species in the Reservoir. style='mso-spacerun:yes'> Water lotus ( style='mso-bidiont-style:normal'>Nelumbo lutea Willd.) was the native species that occurred most often, while alligatorweed (Alternanthera style='mso-bidiont-style:normal'> philoxeroides [Mart.] Griseb.) occurred most often with regard to non-natives. A logistic regression model indicated that as species richness increases, the probability of observing a non-native species also increases. Herbicide evaluations implied that the chemical imazapyr provided the largest biomass reduction in alligatorweed over a twelve week period; …
Effect Of Hunting Frequency On Duck Abundance, Harvest, And Hunt Quality In Mississippi, Elizabeth Anne St James
Effect Of Hunting Frequency On Duck Abundance, Harvest, And Hunt Quality In Mississippi, Elizabeth Anne St James
Theses and Dissertations
Waterfowl hunting is important historically, culturally, and economically in Mississippi and North America. I evaluated effect of hunting frequency (2 or 4 days/week) on duck abundance, harvest, and hunters’ perceived quality of their experience on Mississippi Wildlife Management Areas (WMAs). Neither relative abundance nor harvest of all ducks, mallard (Anas platyrhynchos), northern shoveler (A. clypeata), or green-winged teal (A. crecca) differed between experimental hunting frequencies. Duck harvest increased with hours spent afield. Hunters’ perceived quality did not differ between hunting frequencies but was greatest when hunters harvested > 4 ducks/ day and increased with harvest of larger sized ducks. I suggest …
Deoxygenation Catalysis On Titania For Renewable Fuel Applications, Prashant Reuben Daggolu
Deoxygenation Catalysis On Titania For Renewable Fuel Applications, Prashant Reuben Daggolu
Theses and Dissertations
This research studies the use of class=SpellE>titania (titanium dioxide, TiO2) as a catalyst for deoxygenation of class=SpellE>syngas derived oxygenates. These oxygenates are formed as byproducts when biomass derived syngas (CO & H2) is converted to ethanol on Rhodium or Molybdenum based catalysts. Conversion of these oxygenates to hydrocarbon would enhance the viability of class=SpellE>syngas to gasoline technology. This study revealed that class=SpellE>titania can indeed be used to convert syngas derived oxygenates to hydrocarbon at high temperature and pressure. Acetone condensation to mesitylene was studied very closely. The study revealed that the acid-base dual nature of class=SpellE …
