Studies on the Microbiota of Fishes and the Factors Influencing Their Composition
(2014-07-24)
In this dissertation, I aimed to characterize the microbiota of finfish including identification of the bacteria present as well as the factors that influence their composition. I examined the microbiota of the skin, gill, ...
Studies on the Role of Non-canonical Wnt/JNK Signaling During Early Anterior-Posterior Axis Formation in Sea Urchin Embryos
(2023-05-30)
The establishment of embryonic body axes is a crucial event during early metazoan embryogenesis, determining the correct shape of the adult body plan. Wnt signaling pathways are conserved cascades that regulate important ...
Studies on the Structures and Properties of Bimetallic Uranium Transition Metal and Hybrid Organic-Inorganic Compounds
(2009-06-15)
Hydrothermal synthetic methods have been utilized to synthesize many compounds containing both uranium and transition metals, as well as hybrid organic-inorganic materials. These compounds are found to adopt zero-, one-, ...
Studies on The Synthesis of B-Ring 6-Azasteroids
(2006-08-15)
Azasteroids, which carry a nitrogen in the C-6 position of the steroid nucleus are still
mysterious and very few synthesized, were found to possess antimicrobial and antifungal
properties apart from their pharmacodynamic ...
Studies on the Use of Soil Edaphic Factors for the Development of Site Specific Management Strategies for Rotylenchulus reniformis on Cotton
(2012-08-01)
The reniform nematode, Rotylenchulus reniformis, is currently one of the most limiting factors to cotton production in the United States. With no available commercial host plant resistance, options for management of R. ...
Studies on Wheat Scab in Alabama
(2013-07-09)
Wheat scab is one of the more destructive diseases of wheat in the US. In Alabama, scab was not considered a problem in the past; however, during recent years it has been reported in north Alabama. The overall goal of this ...
Studies to Elucidate the Mechanism of Reduced Flavin Transfer in the Alkanesulfonate Monooxygenase System from Escherichia coli
(2007-12-15)
The two-component alkanesulfonate monooxygenase system utilizes reduced flavin as a substrate to catalyze a unique desulfonation reaction during times of sulfur starvation. The flavin reductase (SsuE) provides reduced ...
Studio-Based Computer Supported Collaborative Learning
(2009-04-23)
The field of computing is experiencing a significant decline in incoming majors. According to the latest reports, the main reasons for this decline are (a) computing is too often related to programming, and (b) introductory ...
Study and evaluation of bigano snail (Stramonita haemastoma) as a marketable seafood species
(2013-12-03)
To evaluate whether a species is potentially edible, marketable and sustainable, we need to answer quite a few questions about what, why, where, who, when and how. This dissertation consists of five chapters. The basic ...
A Study for Playful Product Design
(2012-11-06)
Fuzzy things like sensitivity and emotion have been ignored for decades as topics of scientific study and product design. However, more and more studies are focusing on the emotional side of product design.
Highly developed ...
A study for understanding climate-induced crop production risk and relevant climate hazards in a changing environment
(2024-05-15)
Climate change poses significant challenges to global agriculture by influencing crop production through various climatic factors such as precipitation, temperature, solar radiation, and atmospheric gases. These factors ...
A Study in Capture Capability of E2 Phage, Thiolated E2 Phage, and Anti-Salmonella Antibody for Salmonella Using Magnetoelastic Biosensor Platform
(2018-08-02)
The magnetoelastic biosensor platform is a superior method that can improve food safety and protect from possible bioterrorism versus conventional culture, nucleic acid-, and immunology-based methods due to low cost, ...
