Mathematical Modeling Of Chemical Vapor Deposition Processes And Its Application To Thin Film Technology, Norman W. Loney

Dissertations

A number of workers in the field of Chemical vapor deposition (CVD) have presented mathematical models in the literature. Some workers were able to produce analytical expressions for the interwafer concentration profile. These analytical expressions were based entirely on zero or first order chemical reaction rates. Until now, it appears that a chemical reaction rate expression that is not zero or first order directly, must be handled by a numerical scheme.

Presented herein is a mathematical model with an analytical interwafer concentration profile. This concentration profile is neither zero nor first order but shifts from zero to first order as …

Kinetic Studies On Pyrolytic And Oxidative Decomposition Of Chlorocarbons In A Tubular Flow Reactor, Yang Soo Won

Crime And Development: A Comparative Analysis, Dick Taver'shima Andzenge

Dissertations

The study examines the extent to which social and economic development might be related to crime. Modernization theory of crime posits that the process of social and economic development involves changes in the society which are criminogenic. These changes include: urbanization, industrialization, longevity or increased life expectancy, increased manufacturing and gross domestic products. According to this theory these characteristics alter social tendencies to stability and conformity, and therefore result in increased deviance and crime.

This study tests the theory by using longitudinal data collected over a 25-year period from 54 countries. A sample of these data representing 34 countries from …

A comparative study has been performed between two bioreactors treating phenol, one using calcium alginate entrapped microorganisms, and the other using microorganisms attached on the surface of a polymeric membrane. Laboratory experiments conducted in batch recirculation mode, as well as a continuous feed mode, showed that the calcium alginate bio-bead reactor is more efficient in treating high feed concentrations of phenol, while the membrane bioreactor is more effective in the lower concentration regime (less than 150 ppm). In batch recirculation mode, the reaction rates (expressed as mg phenol/hr*gm dry cells) in the membrane reactor are an order of magnitude higher …

Thermodynamics Of Strong Electrolyte Solutions : Prediction Of Osmotic Coefficients By Pair Correlation Function Method, One Kwon Rim

Dissertations

Thermodynamic properties (osmotic coefficients) of strong electrolyte solutions have been studied by the method of statistical mechanics. First the charged soft sphere potential is developed based on the Pauling type model. Next the charged soft sphere potential is converted to the thermodynamically corresponding charged hard sphere potential by way of the perturbation method developed by Verlet and Weis. Simultaneously, the radial distribution function is developed by modification of the Exponential theory through introduction of the Stillinger-Lovett moment condition. The effective hard sphere diameter values calculated by the perturbation method are combined with the modified Exponential theory, and these quantities are …

The Effect Of Sexual Harassment On Female Naval Officers: A Phenomenological Study, Kathleen Anne Krohne Edd

Dissertations

Sexual harassment has grown to epidemic proportions since being documented as a workplace problem. Court cases are rising along with costs to organizations from litigation, turnover, absenteeism and stress-related medical claims. Courts are continually refining the legal definition of sexual harassment, resulting in a steady expansion of employers' liability. Perceptions of men and women regarding what constitutes sexual harassment differ markedly as do their responses to sexually oriented behaviors at work. Development of a formula for effectively preventing sexual harassment is, therefore, a complex and perplexing exercise. Two of three women serving in the military report that they have been …

The Leadership Process And Its Effects On Self-Managed Work Groups In American Manufacturing Companies, Stephen R. Wirkus Edd

Dissertations

Over the past 75 years, leadership has become a widely studied phenomenon, with many theories and models offered to assist the layman to become an effective leader. Most of these theories have been based on management models, that is, models that adapt management behaviors and goals into what the authors call leadership. These theories fall into several categories: great man, trait, contingency and situational among others. While these theories have provided practitioners some valid ideas on how to improve their managerial effectiveness, they have done little in the way of expanding the knowledge of the process of leadership. This study …

Memory Change And Cognitive Function Among The Elderly, Janet L. Conant Edd

Dissertations

The Problem: The deleterious effects of aging on various cognitive abilities are widely recognized, yet little is known regarding what constitutes "normal" memory test performance in individuals over the age of 74. In this study, forgetting rates for verbal and nonverbal material from the Wechsler Memory Scale-Revised (WMS-R) were examined in groups of older healthy individuals aged 50-74 and 75-95. Despite equivalent scores on measures of global cognitive status and attention/concentration, the older group demonstrated significantly poorer performance on the Delayed Memory Index. Preliminary normative data for normal elderly subjects on the WMS-R are presented, and the need for appropriate …

A Model Of Organizational Commitment In Staff Nurses, Donna Burgener Adams Dnsc

Dissertations

The purpose of this study was to describe and explain the impact of work stress, sex role organization, and organizational tenure on self-esteem and work satisfaction, and ultimately, on the organizational commitment of registered nurses. An eclectic framework was utilized which incorporated organizational and personal variables. The correlational design resulted in a temporally ordered causal recursive model with linkages supported by a literature review. Past research has demonstrated less organizationally committed nurses more prone to leave their positions, and high turnover is detrimental to patient care as well as costly to the health care system. The sample consisted of 143 …

Factors Related To Body Image Appraisal Associated With Receiving Treatment For A Malignant Brain Tumor, Ruth Ann Mulnard Dnsc

Dissertations

Within a stress-coping-adaptation framework, a path analytic model was hypothesized to explain the interrelationships among the variables of gender, age, duration of illness, steroid dosage, social support, perceived health status limitations, and coping skills, and their subsequent effect on body image appraisal in the population of subjects undergoing treatment for a malignant brain tumor. The many potential changes in physical appearance and functional abilities, including the loss of hair, the onset of Cushing's syndrome and varied physical disabilities, may cause devastating alterations in body image, requiring tremendous coping skills for adaptation in these individuals. One hundred and ten subjects were …
