Improving Phosphorus Use Efficiency Through Organically Bonded Phosphorus, Micheal W. Hill

Theses and Dissertations

Current maximum efficiency of phosphorus (P) fertilizers that is utilized by plants in the same year of application ranges from near zero to thirty percent. Despite low utilization of P in crop production, yields are often limited by P deficiencies. Innovative technology is requisite to achieve greater efficiency as fertilizer demands are increasing, while phosphorus mineral resources are rapidly being depleted. A growing environmental concern for nutrient pollution of surface waters also carries significant weight. A novel new product, Carbond® P, is promising technology to increase P use efficiency. Research is needed to understand its capabilities and the functioning mechanisms …

Depletion Of Endothelial Or Smooth Muscle Cell-Specific Angiotensin Ii Type 1a Receptors Does Not Influence Aortic Aneurysms Or Atherosclerosis In Ldl Receptor Deficient Mice, Debra L. Rateri, Jessica J. Moorleghen, Victoria Knight, Anju Balakrishnan, Deborah A. Howatt, Lisa A. Cassis, Alan Daugherty

Saha Cardiovascular Research Center Faculty Publications

BACKGROUND: Whole body genetic deletion of AT1a receptors in mice uniformly reduces hypercholesterolemia and angiotensin II-(AngII) induced atherosclerosis and abdominal aortic aneurysms (AAAs). However, the role of AT1a receptor stimulation of principal cell types resident in the arterial wall remains undefined. Therefore, the aim of this study was to determine whether deletion of AT1a receptors in either endothelial cells or smooth muscle cells influences the development of atherosclerosis and AAAs.

METHODOLOGY/PRINCIPAL FINDINGS: AT1a receptor floxed mice were developed in an LDL receptor -/- background. To generate endothelial or smooth muscle cell specific deficiency, AT1a receptor floxed mice were bred with …

Vibrotactile Feedback Generation Using Envelope Waveforms And Eccentric-Mass Motors, Michael G. Plooster

Theses and Dissertations

The usefulness of vibrotactile feedback as a channel to communicate information has been widely recognized. However, most of the recent work on this subject uses actuators that are either too expensive or too large for many practical applications. This thesis explores the generation of vibrotacatile feedback patterns using a simple, inexpensive eccentric-mass motor that is constrained to use a constant voltage and a low on/off switching frequency. In particular, it explores the pulse timing method, which utilizes the slow transient response of the eccentric-mass motor to calculate pulse and rest times for an arbitrary envelope waveform shape. Several hardware tests …

Impact Of Margin Size On The Predicted Risk Of Radiogenic Second Cancers Following Proton Arc Therapy And Volumetric Modulated Arc Therapy For Prostate Cancer, Laura A. Rechner, Rebecca M. Howell, Rui Zhang, Wayne D. Newhauser

Faculty Publications

We previously determined that the predicted risk of radiogenic second cancer in the bladder and rectum after proton arc therapy (PAT) was less than or equal to that after volumetric modulated arc therapy (VMAT) with photons, but we did not consider the impact of margin size on that risk. The current study was thus conducted to evaluate margin size's effect on the predicted risks of second cancer for the two modalities and the relative risk between them. Seven treatment plans with margins ranging from 0 mm in all directions to 6 mm posteriorly and 8 mm in all other directions …

Recognition Of Compassion Fatigue Among Medical-Surgical Nurses: The Provision Of Education To Manage The Effects, Kandace Woodruff

Doctor of Nursing Practice (DNP) Projects

The Institute of Medicine (IOM) (2010) recommends that healthcare organizations make the “recruitment and retention of qualified nurses a priority”. The ability to comply with the recommendation is fraught with challenges. Nurses are required to care for patients across the age span with varying medical complexities. There are work related stressors which are inherent to the care of a more acutely ill patient population. The tenuousness produced by this type of environment can predispose the nurse to a stress induced phenomenon known as, Compassion Fatigue. The literature is abounding with information related to compassion fatigue among various nursing specialties. However, …

Liquid-Liquid Equilibrium Of Biodiesel Components, Joseph C. Bell

Theses and Dissertations

Biodiesel is produced from vegetable oils through transesterification. Triglyceride mixtures extracted from oilseed feedstocks are upgraded by reaction with an alcohol in the presence of a catalyst to produce fatty acid esters. This reaction produces a mixture of esters, glycerin, alcohol, and catalyst. Separation of the fatty acid esters (biodiesel) and glycerin can be accomplished through liquid-liquid extraction by water addition. Designing liquid-liquid extraction with water as the solvent requires ternary liquid-liquid equilibrium data for mixtures of water, glycerin, and fatty acid esters. Ternary mixture LLE data have been experimentally measured for several of these systems. Those measured include mixtures …

Best Practices Using Building Information Modeling In Commercial Construction, Simon Beveridge

Theses and Dissertations

There has been an increase in adoption of building information modeling (BIM) by commercial contractors over the past few years but there is not a clear indication of current application or the frequency of each use. This research was undertaken to determine the frequency and best practices of using BIM in commercial construction. Leading commercial contracting firms were contacted and employees were selected to complete a telephone survey that was designed to determine how they are using BIM. It was found that BIM is being used with more frequency on projects, with plans to continue to implement it even further …

Efficient Estimation For Small Multi-Rotor Air Vehicles Operating In Unknown, Indoor Environments, John Charles Macdonald

Theses and Dissertations

In this dissertation we present advances in developing an autonomous air vehicle capable of navigating through unknown, indoor environments. The problem imposes stringent limits on the computational power available onboard the vehicle, but the environment necessitates using 3D sensors such as stereo or RGB-D cameras whose data requires significant processing. We address the problem by proposing and developing key elements of a relative navigation scheme that moves as many processing tasks as possible out of the time-critical functions needed to maintain flight. We present in Chapter 2 analysis and results for an improved multirotor helicopter state estimator. The filter generates …

Website Adaptive Navigation Effects On User Experiences, James C. Speirs

Theses and Dissertations

The information search process within a website can often be frustrating and confusing for website visitors. Navigational structures are often complex and multitiered, hiding links with several layers of navigation that user's might be interested in. Poor navigation causes user frustration. Adaptive navigation can be used to improve the user's navigational experience by flattening the navigational structure and reducing the number of accessible links to only those that the user would be interested in. This examines the effects on a user's navigational experience, of using adaptive navigation as the main navigational structure on a website. This study measured these effects …

Interpreting The War Anew: An Appraisal Of Richmond’S Civil War Centennial Commemoration, Brandon Butterworth

Theses and Dissertations

In existence from 1959 to 1965, the Richmond Civil War Centennial Committee was formed for the purpose of planning and executing Richmond’s Civil War centennial commemoration. In this thesis, the author will examine the history of the Richmond Civil War Centennial Committee (RCWCC) and its efforts to develop a new historical narrative of Richmond and the Civil War. This paper will assess Richmond’s previous attempts to commemorate the Civil War and will argue that the RCWCC contributed to the advancement of Richmond’s Civil War narrative by de-emphasizing past Confederate celebration attempts led by heritage groups and advancing a “reconciliation” narrative. …

Investigation Of Possible Novel Peptide Inhibitors To Bag-1 Based On Peptidyl-Biomimetics, Jonathan Brunn

Theses and Dissertations

In this Master’s Thesis Research the results can be summarized from two major tasks: (1) In our first task, we utilized our two protein system (BAG-1 and HSP 70) as part of beta testing of a computational software 1 that can take three dimensional x-ray crystallography information about protein complexes and predict the strength of atom –atom interactions between amino-acid residues Open Contact predicts binding hotspots that can be used to identify short amino acid chains or peptides that mimic that particular binding segment of the larger protein. These peptides are called pepidyl-biomimetics. The peptide can potentially act as an …

Streamlined Extract Preparation For E. Coli-Based Cell-Free Protein Synthesis And Rapid Site-Specific Incorporation Of Unnatural Amino Acids In Proteins, Prashanta Shrestha

Theses and Dissertations

This thesis reports the viability of E. coli cell extracts prepared using equipment that is both common to biotechnology laboratories and able to process small volume samples and expression of proteins containing unnatural amino acids (UAAs) at higher level using PCR amplified linear DNA templates (LETs) in cell-free protein synthesis (CFPS) system. E. coli-based cell extracts are a vital component of inexpensive and high-yielding CFPS reactions. However, effective preparation of E. coli cell extract is limited to high-pressure homogenizers (French press style or impinge-style) or bead mill homogenizers, which all require a significant capital investment. This work specifically assessed the …
