A Sensitivity Analysis Of The Coefficients For The Transformation Of The Electrocardiographic Orthogonal Three-Lead System (Frank) To The Standard Twelve-Lead System, Rasa Ona Draugelis

Loma Linda University Electronic Theses, Dissertations & Projects

The SENSITIVITY ANALYSIS is performed on the transformation coefficients of the Frank XYZ signals generating standard 12-lead ECG with respect to diagnosis. The analysis is adapted for the individual waveform and per each lead. The disease/abnormality categories are described in terms of discrete pattern classes based on criteria used by Marquette Electronics, Inc. The nonlinear global sensitivity analysis method developed by Shuler, et al, is selected for this project. The diagnostic change in the waveform is denoted by a distance measurement from the pattern class boundary corresponding to the best-experimental coefficient estimates (Dower coefficients) to the alternate coefficient specification measurement …

The Effects Of An Intervention Program On Nursing Burnout, Maria Rosa-Morales

Loma Linda University Electronic Theses, Dissertations & Projects

The risk for professional burnout has become commonly recognized and in the past several years has been a focus of research efforts. Nursing is one of the professions generating a high level of stress which results in burnout.

The purpose of this study was to test the effects of an intervention program for nurses who felt they were experiencing burnout. Nursing burnout was defined as a chronic condition of stress among nurses, which leads to a syndrome of emotional exhaustion, depersonalization, and lack of personal accomplishment. The design used was a true experiment. Fifty-two nurses served as voluntary participants who …

The Survival Of Mesophilic And Thermophilic Bacteria Subjected To Uv Irradiation, Sajida A. Shaikh

Masters Theses

Survival curves were determined for the mesophile, Bacillus licheniformis and the thermophile, Bacillus stearothermophilus after subjecting the cells to ultraviolet irradiation. Cells were grown at 37°C for the mesophile and at 55°C for the thermophile.

At low UV exposure times, the thermophile was more resistant to UV irradiation (had a better survival rate) than was the case for the mesophile. At higher exposure times, the situation was reversed, the mesophile having a greater survival rate than the thermophile.

The effect of changes in the temperature during irradiation was also determined. Thermophiles were greatly affected by changes in temperature while the …

Smoking Behavior Among Alabama Student Nurses : The Role Of Behavioral Beliefs And Normative Referencing, Judith Rausch

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to determine predictors of smoking behavior for the senior student nurses in the state of Alabama using Ajzen and Fishbein's Theory of Reasoned Action. Smoking prevalence by level of educational preparation and selected health behaviors were examined for relationship to cigarette use.

A sample of 11 schools of nursing were selected from Alabama's 34, using a random numbers table. There were 13 total programs as two of the schools had both A.D. and B.S. nursing programs. Thirty-two percent (N=555) of senior A.D., B.S. & diploma students nurses in Alabama responded to an 87 item …
