Dual cathode system for electron beam instruments
An electron beam source having a single electron optical axis is provided with two coplanar cathodes equally spaced on opposite sides from the electron optical axis. A switch permits selecting either cathode, and a deflection system comprised of electromagnets, each with separate pole pieces equally spaced from the plane of the cathodes and electron optical axis, first deflects the electron beam from a selected cathode toward the electron optical axis, and then in an opposite direction into convergence with the electron optical axis. The result is that the electron beam from one selected cathode undergoes a sigmoid deflection in two opposite directions, like the letter S, with the sigmoid deflection of each being a mirror image of the other

Edcation\u27s Unsung Heroes
The Alabama African American Historic Project has as its objective to research and document the history and culture of Huntsville, Alabama’s 19th Century African Americans. This project originated from a question asked by students during a field study to Huntsville’s historic Maple Hill Cemetery. While at the cemetery, students located graves of Civil War veterans and former governors of Alabama. Magnificent stories about their lives and outstanding contributions to the city were told. “Where were the African Americans?” was the question asked. This question evolved into Field Studies, Pictorial and Artifacts Exhibits, and Interdisciplinary Units
Using Critical and Creative Thinking Skills to Enhance Integrity in Business Organizations
In this thesis I explore some of the ways in which critical thinking skills can be used to facilitate the development of integrity in business organizations. The vehicle I have developed to bring these thinking skills to organizations is a one-day intensive workshop with a follow-up half-day evaluation session. In chapter one, I define integrity and compare it to Stephen Carter\u27s definition. I also analyze five specific critical thinking skills and relate them to two actual cases: Dow Corning and fictitiously named, First National Bank. In the Dow Corning case, I argue that management might have produced a less destructive outcome had they used critical thinking skills to analyze their problems and come to a resolution. In the second case, with First National Bank, I discuss how the bank managers successfully used critical thinking skills to arrive at an ethical decision. In chapter two, I present the workshop which is designed to develop critical thinking skills and enhance integrity. The last part of the chapter is concerned with evaluating and reinforcing the skills developed in the workshop. In chapter three, I integrate the material from the first two chapters. I review Carter\u27s definition of integrity and examine it in light of the five critical thinking skills, the workshop skills and the Dow Coming and First National cases. Those who read this thesis should come away with a clear idea of some ways in which critical thinking can facilitate the development of integrity in business organizations
Structured COPD Discharge Education and Quality of Life: A Feasibility Evaluation
Background: Multiple internal and external factors are responsible for the development and progression of chronic obstructive pulmonary disease (COPD). Noxious stimuli such as cigarette smoking and other air borne pollutants set off the ongoing inflammatory process of COPD resulting in air flow limitation and lung tissue destruction. Objectives: Examination of inflammatory mediators of COPD and risk factors that coincide with hospital admission for AECOPD. The aim of this dissertation was to conduct a feasibility study to implement an educational intervention for hospitalized patients and evaluate their quality of life (QOL), using the RE-AIM framework to evaluate outcomes. Design: This dissertation includes three papers: a principle-based concept analysis on inflammatory mediators related to COPD, an integrative review of the psychometric instruments used to measure risk factors for hospitalization among patients with COPD, and a feasibility study using the American Lung Association’s modified COPD Action Plan to instruct patients with COPD on identifying early signs of an exacerbation and when to seek medical care. In addition, quality of life perceptions were evaluated using the World Health Organization-BREF (WHOQOL-BREF) before hospital discharge and 30 days post discharge via phone call. Conclusions: COPD is a complex chronic disease with an insidious onset by inflammatory mediator(s) or genetic origin. The episodic acute exacerbations of COPD (AECOPD) are responsible for high healthcare utilization and perceptions of low quality of life. The feasibility study results suggest implementation of the American Lung Association modified COPD Action Plan can be carried out as discharge instructions and QOL evaluated using the WHOQOL-BREF questionnaire. Positive ratings and comments on the delivery and content of the COPD Action Plan were found in a small sample of participants who responded to follow up

Periodic Variation of Stress in Sputter Deposited Si/WSi2 Multilayers
A tension increment after sputter deposition of 1 nm of WSi2 onto sputtered
Si was observed at low Ar gas pressures. Wafer curvature data on multilayers
were found to have a periodic variation corresponding to the multilayer period,
and this permitted statistical analyses to improve the sensitivity to small
stresses. The observation of tension instead of compression in the initial
stage of growth is new and a model invoking surface rearrangement is invoked.
The data also bear on an unusual surface smoothing phenomena for sputtered Si
surfaces caused by the sputter deposition of WSi2 . We furthermore report that
for low Ar pressures the Si layers are the predominant source of built-up
stress
