The purpose of this research was to determine residual control and concentrations in flowering structures of commonly used insecticides. This research focused on the concentrations of active ingredient within the plant as well as efficacy over time. Previous research suggested chlorantraniliprole had a long residual and was highly lethal on corn earworm up to 28 days after treatment (DAT) in soybean; however, the results found in cotton were …

A Novel Chebyshev Wavelet Method For Solving Fractional-Order Optimal Control Problems, Ghodsieh Ghanbari

Theses and Dissertations

This thesis presents a numerical approach based on generalized fractional-order Chebyshev wavelets for solving fractional-order optimal control problems. The exact value of the Riemann– Liouville fractional integral operator of the generalized fractional-order Chebyshev wavelets is computed by applying the regularized beta function. We apply the given wavelets, the exact formula, and the collocation method to transform the studied problem into a new optimization problem. The convergence analysis of the proposed method is provided. The present method is extended for solving fractional-order, distributed-order, and variable-order optimal control problems. Illustrative examples are considered to show the advantage of this method in comparison …

Evaluating The Role Of Area, Isolation, And Human Behavior On Meso-Mammals In A Small Statistical Demographic Area, Brittney Palode

Theses and Dissertations

Urbanization offers unique challenges for wildlife. The urban landscape is fragmented and changes available resources for wildlife. Human-dominated landscapes can provide food, shelter, or cover through human-subsidized resources. However, to thrive in human-dominated landscapes, wildlife must adapt or disperse, otherwise they will die. In this study, I investigated how the urban landscape and human behavior influence urban wildlife occurrence. I established 35 camera sites during April 2020. I surveyed residential property dwellers around each camera site to determine what behavior they performed that could increase species occurrence. Gray fox and coyote site use decreased with increased isolation while no species …

Mapping For Meaning In A Multimodal Web: Advancing Learning Using Web-Based Instruction That Stimulates Wayfinding Behavior, Rhonda Lee Thomas

Theses and Dissertations

When learners cannot find their way through web-based instructional information, they become lost, as a result, learning stops. The operations of human wayfinding behavior (or simply, wayfinding) are the cognitive processes activated when humans must make decisions on how they will move through, primarily, novel situations. This paper examines the utility of incorporating the operations of wayfinding into instructional design models to reduce the likelihood of learners becoming lost in web-based instructional information.

The Impact Of High- Vs. Low-Load Resistance Training On Measures Of Muscle Activation, Strength, Body Composition, And Hormonal Markers, Marissa Laina Bello

Theses and Dissertations

Resistance training has shifted towards a high- vs low-load training approach. Heavier loads are suggested to maximally recruit motor units and optimize strength adaptations, whereas lower loads stimulate hypertrophy. However, a majority of the research has not used a true strength range when assessing load. Therefore, the purpose of this investigation was to examine and determine significant differences in strength, body composition, and hormonal markers over nine weeks of high- or low-load resistance training. Secondary purposes of the current investigation were to assess and quantify training load for resistance training using sEMG sensor-embedded compression shorts. 17 recreationally-trained males were randomized …

Gene Expression Analysis Revealed The Activation Of Immune Responses During The Postnatal Development Of The Cerebellum In A Mouse Model Of Niemann-Pick Type C, Sierra Elizabeth Melli

Theses and Dissertations

Niemann-Pick Type C (NPC) is a recessive neurodegenerative lysosomal storage disorder that is caused by autosomal recessive mutations. The mutations result in the inactivation of NPC1 and NPC2 proteins. Inactivation of the NPC1 protein results in the accumulation of cholesterol within the endosomal and lysosomal compartments of cells including Cerebellar Purkinje cells. This accumulation of cholesterol leads to symptoms of dementia, neurodegeneration and potential of early childhood death in cases of early onset. In this study, we analyze the gene expression levels using the RNAseq technique in order to determine whether there is a significant difference between the expression of …
