| A Fermi-style thermal neutron disc chopper was designed, constructed, and calibrated in conjunction with a boron-loaded organic scintillator for use in creating a forward edge neutron time-of-flight spectroscopy technique. The forward edge neutron time-of-flight spectroscopy technique inferred the characteristics of a neutron energy spectrum. The system analyzed the spectrum of a moderated and unmoderated PuBe source with the aid of a MATLAB code. Through the use of pulse shape analysis ... |

| Human papillomavims (HPV) types infect the skin and mucosal epithelium. Lesions resulting from HPV infection can linger for months or years suggesting that HPV - presence goes unnoticed by the host immune system. If allowed to persist, the high-risk HPV types can result in malignant cellular transformation and eventual progression to invasive carcinoma. The importance of the immune system in clearing HPV infection is substantiated by studies involving immunocompromised individuals. ... |

| Small ruminants represent an important role in the pastoral life of the Maasai people of northern Tanzania. Although the Maasai culture centers on cattle, East African goats and Fat-tailed sheep are the predominant livestock in this area and are extensively managed on free range semi-arid landscape. The milk and meat from these animals are a main component of the Maasai diet. The milk is often consumed hot, combined with tea ... |

ABSTRACT: In situ chemical oxidation (ISCO) using permanganate is a promising technology for remediating groundwater and soil contaminated by chlorinated solvents present as dense non-aqueous phase liquids (DNAPLs). However, there remain gaps in knowledge about ISCO effects on mass depletion from complex DNAPL source MnO2(s) formation, impacting field application of the technology. Further, ... |

| Accurate tropical cyclone (TC) intensity estimates are best achieved from satellite observations. The Advanced Microwave Sounding Unit (AMSU) has operated since 1998 on polar-orbiting environmental satellites and is able to measure the warm temperature anomaly in the upper troposphere above a TC's center. Through hydrostatic equilibrium, this warm anomaly is roughly proportional to the TC's sea-level pressure anomaly. Based on this principle, the Cooperative Institute for Meteorological Satellite Studies (CIMSS) ... |

| When a non-US spacecraft reenters the Earth's atmosphere, having the ability to accurately determine its performance characteristics is a primary concern. This study investigated the atmospheric re-entry profiles of a maneuverable re-entry vehicle. The re-entry vehicle was modeled as a point mass with aerodynamic properties. Equations of motion were numerically integrated, giving the time histories of position, velocity and flight path angle. The algorithm is able to generate a complete ... |

| Federal environmental remediation projects are laden with risks - risks that are often undetectable before remediation work begins. Recognizing they cannot specifically account for such unknown contingencies via contract, the Government and remediation contractors employ contractual and insurance-based methods to shift or reduce their respective risks. This thesis examines and critiques the effectiveness of such risk-shifting measures as they pertain to the Government, the remediation contractor, and, most importantly, getting ... |

| One of the functions of nurses is to assist individuals to achieve a peaceful death. In order to fulfill this role, patient end-of-life wishes must be communicated to family members and health care providers. Since passage of the Patient Self-Determination Act (PSDA) in 1990, advance directives have served as the legal vehicle and communication tool for bringing about an understanding of these wishes, should the patient be unable to competently ... |

| Emdogain (trademark) or enamel matrix derivative (EMD), is a preparation of matrix proteins derived from developing porcine teeth. Although EMD has been shown to enhance both soft tissue healing and regeneration of the periodontium, the mechanism of this action is still unknown. It is assumed, but not yet proven, that amelogenin, the most abundant protein in EMD, is the protein primarily responsible for the effects of EMD. The purpose of ... |

| In order to solve the dynamics of a system, the kinetic energy operator of the Hamiltonian must be diagonalized. Diagonalization requires rotation of the system into a non-adiabatic representation. This rotation is a coupling angle determined by the derivative coupling terms. Derivative coupling terms are calculated using Columbus and Brooklyn, software packages. Separation of internal dynamics characterized by Jacobi coordinates, and external dynamics characterized by a set of Euler angles ... |

| This research examines the performance of a spectrally encoded, multi-carrier, phase shift keying communications system in a frequency-selective, slowly-fading multipath channel. The specific communications system modeled is the transform domain communication system (TDCS) originally researched as an interference avoidance technique. Previous TDCS research assumed an additive white gaussian noise channel, which is not representative of a realistic environment. This thesis presents overviews of previous TDCS research, the multipath fading channel, ... |

A rally 'round the flag effect did occur at the outset of the Iraq War, which caused Republicans, Democrats and Independents to support the war. Both party affiliation and news attentiveness explained a significant amount of variability in a person's opinion of ... |

| Although mortality related to heart failure (HF) is high, the number of patients living with HF increases annually. Therefore, health status is an increasingly important concept in the management of HF. In fact, most symptomatic patients are more concerned about their everyday health status than the length of their life. Yet, most investigators conduct intervention studies that are designed to reduce mortality. As a result, health status is poorly understood ... |

| Current limitations of atmospheric predictive skill are investigated through comparison of correlation and error statistics of operational and research global models for two boreal winter seasons. In 1993, bias-corrected models produced anomaly correlations of 0.6 after 7 days, with relatively little forecast skill beyond that point. In 2003, the forecast skill of a more developed, higher-resolution operational model has been extended 36-48 h, while the skill of the unchanged, low-resolution ... |

| With regard to heat stress, the limiting factor inherent in clothing ensembles is the total evaporative resistance. For the same work demands, clothing with higher evaporative resistance impedes the ability to cool by sweat evaporation. Knowing the evaporative resistance provides a means to compare candidate ensembles. Further, a value for evaporative resistance means that a rational method can be used to assess the heat stress exposure. Evaporative resistance of five ... |

They include the effect of gravity, as well as constraints on the terminal flight path and heading angle, and are designed for tracking moving targets. These guidance laws yield equations for the commanded accelerations. They are based firmly on optimal control theory and meet the first and second variation necessary conditions that originate from Pontryagin's Minimum ... |
