Binding affinity between two molecules is an essential property in drug and sensor discovery. Several computational and experimental methods exist to find molecules with high binding affinities to desired target molecules. These methods are often complementary, where fast computational methods can be used for the initial screening of molecules, and experimental methods can then screen and determine the molecules of interest and sometimes define the structures of bound complexes. After these steps, computational methods, like molecular dynamics (MD) simulations, can provide detailed insights into atomic interactions and binding, and machine learning approaches can analyze experiment-derived data to discern patterns and …

Evaluation Of The Efficacy Of Synthetic Glycovaccines Against Both Murine Acute Chagas Disease And Cutaneous Leishmaniasis, Colin D. Knight

Open Access Theses & Dissertations

Chagas disease (CD) and cutaneous leishmaniasis (CL) are neglected tropical diseases caused by the protozoan trypanosomatids, Trypanosoma cruzi and Leishmania spp., respectively. There are approximately 6-8 million people infected with T. cruzi worldwide and ~300,000 people in the US. Between 700,000 and 1.2 million new cases of CL occur worldwide yearly. The approved chemotherapies for both diseases are partially effective and may cause serious adverse events, resulting in premature treatment interruption. Moreover, no effective vaccine for either disease is available. Therefore, developing a vaccine that would provide effective cross-protection against both diseases would provide a cost-effective alternative to the existing …

Tess Of The D'Urbervilles -- A Pure Survivor An Analysis Of Thomas Hardy, Victorian Women, & Modern Media, Jesse C. Marin

Open Access Theses & Dissertations

Context is vital to understanding the circumstances and the society that produced Thomas Hardy’s novel.

Using Shallow Electromagnetic And Magnetic Techniques To Map Soil Texture And Characterize Salinity And Water Dynamics Below Pecan Orchards, El Paso County, Texas, Kristina Sasser

Open Access Theses & Dissertations

Non-invasive, near surface geophysical tools provide a time efficient and cost-effective approach to study the shallow subsurface. Electromagnetic induction (EMI) instruments are a category of these near surface methods that provide spatial and temporal information (2-D to 4-D) about shallow (<6 m) subsurface properties, from which soil salinity, clay content, and water content can be estimated. However, deconstructing soil apparent electrical conductivity (ECa) from EMI methods into its component parts remains a challenge. This research uses EMI and magnetic geophysical techniques to: (1) compare and contrast the distribution and behavior of ECa, both spatially and temporally, at two flood irrigated agricultural sites (pecan orchards) with different soil layers, properties, and controls on electrical conductivities that lie within the same floodplain in far west Texas; and (2) develop a one-dimensional inversion model using ECa and soil texture data at specified layers from established sites of known high and low ECa to determine soil layer resistivities at various dates during the irrigation season. Data are compared to soil sensor bulk EC and volumetric water content data at corresponding depths to validate results. Soils at both sites exhibit large ECa contributions from textural controls, and irrigation frequency. The combination of these two controls dictate where and how quickly secondary minerals precipitate, clog soil pores, reduce infiltration, and salinize the groundwater. Insight from this research aids in ongoing efforts to characterize vadose zone hydrology in dryland critical zones with high infiltration and serves as a guide for locations where future soil sampling will occur.

The Blueberry Gall Midge Complex And Its Specialist Parasitoids, Monique Michele Raymond

Master's Theses and Capstones

The cosmopolitan blueberry gall midge complex causes serious damage to the terminal vegetation of blueberry plants. The nature of their infestation, paired with prolonged periods of abundance, requires an integrated pest management approach. Of all known parasitoids present in the system, members of the subfamily Platygastrinae are the only oligophagous clade specialized against true gall midges. In this study, we present the results of blueberry gall midge and platygastrid surveys in high- and low-bush blueberry crops in the northeastern and southeastern United States, along with an identification key, with emphasis on blueberry parasitoid Synopeas species to facilitate their identification.

A History Of Complex Simple Lie Algebras, Avrila Frazier

Electronic Theses and Dissertations

In 1869, prompted by his work in differential equations, Sophus Lie wondered about categorizing what he called “closed systems of commutative transformations,” while around the same time, Wilhelm Killing’s work on non-Euclidean geometry encountered related topics. As mathematicians recognized this as a division of abstract algebra, the area became known as “continuous transformation groups," but we now refer to them as Lie groups.

Patterns and structures emerged from their work, such as describing Lie groups in connection with their associated Lie algebras, which can be categorized in many important ways. In this paper, we focus on Lie algebras over the …
