Radiation heating in selected NERVA engine components

The role of heating from nuclear radiation in design of the NERVA engine is treated. Some components are subjected to very high gamma heating rates in excess of 0.5 Btu/cubic inch/sec in steel in the primary nozzle or 0.25 Btu/cubic inch/sec in aluminum in the pressure vessel. These components must be cooled by a fraction of the liquid hydrogen propellant before it is passed through the core, heated, and expanded out the nozzle as a gas. Other components that are subjected to lower heating rates such as the thrust structure and the disk shield are designed so that they would not require liquid hydrogen cooling. Typical gamma and neutron heating rates, resulting temperatures, and their design consequences are discussed. Calculational techniques used in the nuclear and thermal analyses of the NERVA engine are briefly treated

ECONOMIC ANALYSIS OF TEMIK ON CITRUS IN THE INDIAN RIVER AREA IN SOUTHEASTERN FLORIDA

Temik [R](aldicarb) is a pesticide labeled for use on several citrus crops to control rust mite, whitefly, nematode and brown citrus aphid pests. Analysis of previous research experiments indicates that this pesticide is beneficial to both orange and grapefruit production and that both cost savings and higher yields can be experienced in many types of groves. Actual grove data shows that net returns for mature grapefruit that receive Temik [R] can be $500 per acre greater than net returns for identical acreage that uses other pest control options. Also, based on grove reset data it is shown that with an application of Temik [R] the resulting increased yields for three-year-old trees more than cover the additional cost of applying the Temik [R].mature citrus, resets, revenue-cost, net return, grapefruit, Crop Production/Industries,

Using Second Harmonic Generation to Study Gram-Positive Bacterial Membranes

Understanding how small-molecules, such as drugs, interact with bacterial membranes can quickly unravel into much more perplexing questions. No two bacterial species are alike, especially when comparing their membrane compositions which can even be altered by incorporating fatty acids from their surrounding environment into their lipid-membrane composition. To further complicate the comparison, discrete alterations in small-molecule structures can result in vastly different membrane-interaction outcomes, giving rise to the need for more label-free studies when analyzing drug mechanisms. The work presented in this dissertation highlights the benefits to using nonlinear spectroscopy and microscopy techniques for probing small-molecule interactions in living bacteria. A large aim of this work focuses on the theory and applications to utilizing two nonlinear optical phenomena, second harmonic generation (SHG) and two-photon fluorescence (TPF), for understanding environmental and lipid-membrane composition effects on small-molecule uptake and transport in bacterial systems, such as: Enterococcus faecalis, Staphylococcus aureus and Escherichia coli. SHG and TPF simultaneously monitored the uptake and transport of two membrane-associated probe molecules in two gram-positive bacterial species, E. faecalis and S. aureus. Only SHG was employed for monitoring the gram-positive antibiotic, daptomycin, interactions under different environmental conditions and calcium-ratios with the gram-positive species E. faecalis and S. aureus, and the gram-negative species E. coli as a control

The Fundamentals of GAAP: Case Studies of Accounting Principles

The following paper consists of solutions to case studies that provide an overview of accounting principles in accordance with the Generally Accepted Accounting Principle set forth by the Financial Standards Accounting Board. Each case addresses a different area of financial reporting within a specific company, and demonstrates comprehension and practice of accounting concepts, financial analysis, and preparation of financial statements. These cases were completed under the direction of Dr. Victoria Dickinson in fulfillment of the requirements for the University of Mississippi ACCY 420 honors course in the 2016-2017 academic year

“A Show about Language”: A Linguistic Investigation of the Creation of Humor in Seinfeld

This study investigates the creation of humor in the dialog of the television sit-com Seinfeld to gain a deeper understanding of humor techniques in a long format. By analyzing six episodes of the series, it is seen that the Incongruity Theory of Humor, violations of Grice’s maxims of the Cooperative Principle, and perspective clashes (such as miscommunications) are essential to the humor throughout each episode

The Performance of Melancholy: Understanding the Humours through Burton, Jonson, and Shakespeare

This thesis aims to explore the relationships between dramatic texts and the Elizabethan topic of the humours. It covers Burton\u27s Anatomy of Melancholy, Jonson\u27s plays Every Man Out of His Humour and Every Man in His Humour, and Shakespeare\u27s plays Hamlet and As You Like It. Each of these works provides a glimpse into society and its opinions specifically on melancholy, from its most basic and complex definitions to how it is perceived and addressed

A study of Military Health Care Costs: Direct versus Purchased Care in a Geographical Region

Health care expenses are one of the largest contributing factors to increased personnel costs, the fastest-rising component of the Department of Defense\u27s budget. This research examines the cost implications of developing a new military treatment facility in a specified geographical region, in an effort to reduce military health care spending. Care received at a military treatment facility is referred to as direct care, while care received in the private sector is referred to as purchased care. This research leverages existing information on direct and purchased medical care to gain insights into the workload costs for medical care in a geographical region. This research uses a Monte Carlo simulation approach to determine the direct and purchased care costs for general surgery and orthopedic specialties. The method is applied to the Atlanta, Georgia region and conclude that based on workload measures, it is cheaper in Atlanta to provide direct care at a new military treatment facility
