Analysis Of Bacteriorhodopsin Suspended In A Bilayer Lipid Membrane, Moath Alhejji

Graduate Theses and Dissertations

The bacteriorhodopsin protein’s unique characteristic of proton pumping can convert light energy to electric energy. The aim of this research was to generate photocurrent using bacteriorhodopsin in a bi-layer lipid membrane. Lipid monolayer and bilayer were formed using painting and folding methods, respectively. Capacitance and resistance of the lipid membranes were measured and used to validate the best methodology. My results show that the folding method is more efficient in incorporating Bacteriorhodopsin. The photocurrent was generated by illuminating a green laser (532 nm) on the bilayer lipid membranes. The patch clamp electrophysiology technique was used to apply voltage across the …

Stress Among Ncaa Division Ii Head Coaches, Dee Gerlach

Graduate Theses and Dissertations

The purpose of this quantitative study was to identify factors that create stress among head coaches at the National Association Athletic Association Division II level. Data was collected through a demographic questionnaire and the Coaching Issues Survey (CIS), a tool used to measure specific factors that may create stress among coaches. The factors of the CIS include four subscales: Athlete-Concerns, Time-Role, Program-Success, and Win-Loss. Participants (N=416) consisted of head coaches representing the following sports: baseball, men’s basketball, women’s basketball, men’s golf, women’s golf, men’s and women’s golf, softball, women’s tennis, and men’s and women’s tennis. The independent variables for this …

Efficacy Of Selected Powdered Floor Treatments And Turmeric Rhizome Powder Against Salmonella, E. Coli, And L. Monocytogenes On Polyurethane-Concrete Flooring Material Carriers, Robert Sidney Fuller

Graduate Theses and Dissertations

The flooring in a food processing environment can become contaminated with pathogenic bacteria in many ways including foot and equipment traffic, incoming materials, and drain backups. Turmeric (Curcuma longa L.) rhizome powder and seventeen other commercially available powdered floor treatments with a variety of active ingredients including quaternary ammonium compounds (QAC), sodium percarbonate and similar perhydrates (SPC), urea, and borax, were investigated for reducing the levels of pathogens on flooring thereby reducing the risk of cross-contamination from the floor to food contact surfaces. Some of the commercially available floor treatments were Environmental Protection Agency (EPA) registered antimicrobials while others were …

Investigation Of Iron-Nickel Films Based Catalysts: Controlling Hydrogen Evolution Reaction (Her) Through An Electrode-Electrolyte Engineering Approach, Sergio Ivan Perez Bakovic

Graduate Theses and Dissertations

Electrochemical energy conversion technologies need to be economically viable in order to be adopted. Earth-abundant transition metals (i.e., Fe, Co, and Ni) have attracted attention due to their high availability, low cost, and catalytic characteristics that are in many cases found in and exploited by nature. Herein, we synthesize FexNi100-xOy electrocatalyst films and study how the electrocatalyst-electrolyte interactions alter the hydrogen evolution reaction (HER).In this work, FexNi100-xOy films were synthesized to study the composition, chemical state, and morphology. Characterization results provided a well-established electrocatalyst film platform to then proceed with electrochemical evaluations. The effects of the electrode composition and electrochemically …

A Case Study Of Eastern Region Arkansas Promise Participants And Their Expectations For The Future, Robin Freeman

Graduate Theses and Dissertations

The purpose of this study was to develop an in-depth understanding of how Eastern Arkansas youth with disabilities and their parents describe their expectations for the future, after participating in the Arkansas PROMISE program. The study sought an understanding of how participants viewed themselves and their expectations for the future, for employment, for participation in higher education, for independent living, and for future financial support. The research used a case study approach, interviewing five students and five parent participants. Participants were asked a series of questions to get an understanding of their experiences, their expectations for the future, and their …

Catalytic Activity Of Molybdenum-Dioxo Complexes, Randy Tran

Graduate Theses and Dissertations

This dissertation details the development of rationally designed dioxomolybdenum catalyst active for deoxydehydration (DODH), the net reduction of diols and polyols into alkenes and dienes. Catalyst design involved variations on dioxomolybdenum(VI) supported by a dianionic meridional pincer ligand. Rational substrate scope was explored using aliphatic diols, aromatic diols, and biomass derived diols. Various reductants were tested for ability to catalyze the reaction. The substrate specific mechanism of DODH was explored utilizing NMR and in-situ infrared spectroscopy and important rate constants and rate determining steps were found to aid in the optimization of ideal reaction conditions. Catalytic activity was observed to …

Voltage And Frequency Control In Ac Islanded Microgrid, Hamad Mohammad Al Sharif

Theses

Microgrids are described as linking many power sources (renewable energy and traditional sources) to meet the load consumption in real-time. Because renewable energy sources are intermittent, battery storage systems are required, typically used as a backup system. An energy management strategy (EMS) is required to govern power flows across the entire microgrid. In recent research, various methods have been proposed for controlling the micro-grids, especially voltage and frequency control. This study introduces a microgrid system, an overview of local control in the microgrid, and an efficient EMS for effective microgrid operations using three smart controllers for optimal microgrid stability. We …

Two-Way Load Flow Analysis Using Newton-Raphson And Neural Network Methods, Aya Emad Omar Al Shaltouni

Theses

This research presents a study of the optimal power flow for networked microgrids with multiple renewable energy sources (PV panels and wind turbines), storage systems, generators, and load. The OPF problem is performed using a conventional method and an Artificial Intelligence method. In this research, we investigated the performance of MGs system with renewable energy integration with focus on power flow studies. The calculation of the power flow is based on the well-known Newton-Raphson method and Neural Network method. The power flow calculation aims to evaluate the grid performance parameters such as voltage bus magnitude, angle, real and reactive power …
