Enthalpies Of Solution Of Co2 In Aqueous Methyldiethanolamine Solutions, Keith E. Merkley

Theses and Dissertations

The enthalpies of solution, H^S, of carbon dioxide in aqueous methyldiethanolamine were measured with an isothermal flow calorimeter over wide ranges of temperature, pressure, weight percent MDEA, and loading (gmole CO₂/gmole MDEA). The values of H^S (kJ/gmole CO₂) were found to be constant up to the saturation concentration of CO₂ in the aqueous solution. In addition, experimental data showed that H^S was independent of the total pressure over the solution, but linearly dependent upon both temperature and weight percent MDEA as was given by a correlation. A computer program based upon …

Assessment Of Influence That The Church Of Jesus Christ Of Latter-Day Saints Has On Exercise Habit Of Members Living In Utah County, Gary L. Preston

Theses and Dissertations

This study identified and analyzed the influence the Church of Jesus Christ of Latter-day Saints had on the decision of 309 respondents to exercise. The data obtained from the questionaires were analyzed using chi-square to compare males and females. Within the limitations of this study, the following conclusions were justified: women were more influenced by the LDS Church to exercise than men; LDS males and females exercised more than average American adults; walking, jogging, and aerobic dance were the most popular choices of LDS exercisers; and, there is a need to improve the awareness of LDS members concerning the Physical …

An Evaluation Of The Effectiveness Of A Substance Abuse Awareness And Prevention Program Developed For Use With University-Level Varsity Student-Athletes, Robert Joseph Marcello

Theses and Dissertations

Substance abuse problems affect all segments of society including collegiate athletics. Drug testing programs are viewed as one method of combating this problem, however, more emphasis should be placed upon developing effective prevention programs. Towards this end, the first purpose of this study was to draw from available literature to design a prevention program which would cater to the specific needs of student- athletes. The position is taken that since multiple factors such as genetic predisposition, the pharmacological properties of various substances, psychological variables, and environmental/socio-cultural influences are implicated in the etiology of substance abuse difficulties, multi-focused/broad-spectrum intervention programs would …

Control Of Hospital Strategy In Small Multihospital Systems, Lora Hanson Warner

Theses and Dissertations

Hospitals are joining multihospital systems (MHSs) with growing frequency. About 80% of MHSs are small, composed of 2-7 hospitals. An important management issue in MHSs is the extent to which member hospitals retain control over their own strategic directions.

Using a contingency framework, this study uses both system and hospital—level determinants to explain the extent to which hospital members of MHSs control their own strategies. Survey and secondary data from 272 member hospitals of 62 small multi hospital systems (size 2-7 hospitals) are analyzed. System dispersion, size, ownership, strategic type, and age along with hospital occupancy, size, relationship to the …

Nosocomial Respiratory Tract Infections Associated With The Use Of Ventilatory Support Systems: Epidemiological And Bacteriological Study Of The Effect Of Changing Breathing Circuits At 24 Or 48 Hours, Virginia Archer Lamb

Theses and Dissertations

Nosocomial (hospital-acquired) pneumonia (HAP) continues to be an important cause of morbidity and mortality in the hospital. HAP is the third most common nosocomial infection after urinary tract and surgical wound infections. In addition, HAP is the nosocomial infection with the highest mortality rate. These infections are often difficult to treat, because most are caused by Gram-negative bacilli (GNB) that may be highly resistant to antimicrobial agents. HAPs frequently occur in intensive care patients with underlying lung and/or systemic diseases. Many patients are intubated and are on assisted ventilation. Several sources of infection associated with ventilators or respirators have been …

An Investigation Of Critical Thinking Levels And Prospective Teachers., Amy Lynn Gillett

Theses and Dissertations

The intention of the researcher was to discover the level of critical thinking skills of undergraduate teacher education students attending the University of North Dakota (UND) during the spring semester of 1987. The Watson-Glaser Critical Thinking Appraisal (CTA) was used to identify the level of critical thinking of the participants. A demographic data sheet was prepared by the researcher from which general data were gathered for the study.Data were analyzed by analyses of variance, multiple comparisons of means, and a simple t-test. No significant results were found among the different majors (elementary, secondary, elementary/early childhood, elementary/special education) and their scores …

Histamine Receptors And Cyclic-Amp Levels In Rabbit Coronary Arteries., Dale Arthur Schuschke

Theses and Dissertations

Histamine is known to cause an H$\sb 1$-receptor mediated vasoconstriction and an H$\sb2$-receptor mediated vasodilation in the coronary vasculature of the rabbit heart. In this study we looked at the role that the adenyl cyclase-cyclic AMP system plays in mediation of the histamine response in the vascular smooth muscle. Change in perfusion pressure in the isolated rabbit heart was used as the index of change in vascular tone when histamine was added to the perfusate. The vascular response to histamine was then studied while cAMP levels were altered by adenyl cyclase potentiation and phosphodiesterase inhibition. After the physiological responses of …

Electrochemical Kinetic And Mechanistic Study Of Reductive Cleavage Of Phenyl-Substituted Aryl Ethers., Todd A. Thornton

Theses and Dissertations

The electrochemical cleavages of diaryl ethers were studied. The radical anions or dianions of diphenyl ether, 1-phenoxynaphthalene, and 9-phenoxyanthracene were generated electrochemically. The cleavage reaction rates were measured and mechanisms of each cleavage reaction were postulated.Direct reduction of diphenyl ether was observed to be by one-electron at $-2.98$ V vs. SCE. A homogeneous redox catalysis process with acenaphthene as electron mediator was used to determine the rate of cleavage. Cyclic voltammetry was used to acquire peak current data. The radical anion of diphenyl ether was found to cleave by a unimolecular pathway at a rate of 4 $\times$ 10$\sp5$s$\sp{-1}$. A …

Freshman Football Players' Preceptions Of Factors Influencing Their Choice Of College, Ross Fortier

Theses and Dissertations

"

The purpose of the. study wtt'js to exai^.ne the question of why graduating high school football players make the college selection they do. The study sought to determine what factors influence athletes' decisions at three types of colleges and whether these factors are different for students from different academic, athletic, or socioeconomic backgrounds. An instrument was developed by the writer and administered to freshman football players at six selected small colleges in the upper midvestern United States.

Dietary Restraint And The Salience Of Visual Food Cues, Jeanine Elaine Kotschwar

Theses and Dissertations

A review of the literature reveals significant changes which have oc- cured in the role posited for dieting. Once considered a simple solution for weight loss, dieting has more recently been seen as playing a causal role in the development of eating disorders. Similarly, the characteristics and behaviors once thought to be attributable to obesity have more recently been said to be by-products of dieting-induced hunger. Several authors have pointed to the influence of cognitive factors in initiating and maintaining dieting and, conversely, in abandoning restraint in eating.

The purpose of this study was to explore the influence of dietary …
