Use Of Infrared Spectrometry To Determine The Effect Of Temperature On The Description Rates Of Trichloroethylene From Plastic Clay 98b, Abdellatif Fares

Theses and Dissertations

This thesis investigated the influence of temperature on the desorption rated of trichloroethylene (TCE) from plastic clay. It was expected that an increase in temperature will cause an increase in both the desorption rates of TCE and in the desorbed quantity. Previous studies on other chemicals indicated a faster decrease in the remaining sorbed concentration with an increase in temperature. This research made use of the infrared optical absorption technique. IR spectroscopy was used to measure the concentration of the vapor TCE that desorbed from the soil. The soil was exposed to liquid TCE for 2 days then placed inside …

Changes In Nursing Students' Knowledge Of Bloodborne Pathogens And Perception Of Safety In Practice From Sophomore To Senior Years In School, Ellen J. O'Connor

Theses and Dissertations

Bloodborne pathogens have received increasing attention since Acguired Immune Deficiency Syndrome (AIDS) became known in the United States. Until that time, antibiotics, immunizations, and increasingly sophisticated infection control practices had markedly decreased health care workers' occupational risk for contraction of bloodborne and other infectious diseases. From a nursing education perspective, it was important to ascertain knowledge deficits students have related to caring for clients infected with Human Immunodeficiency Virus (HIV) and the Hepatitis B Virus (HBV).

Therefore, the purposes of this study were to compare sophomore and senior nursing students relative to: a) their knowledge of bloodborne pathogens (particularly HIV …

Parents' Reactions To The Sexual Abuse Of Their Children, Donna Greifer

Theses and Dissertations

The present study examined 100 parents' predictions of their reactions to child sexual abuse. Subjects consisted of two groups, parents with a self-reported history of sexual abuse and parents with no reported history of sexual abuse. They were assigned to one of three experimental conditions to consider a case where their own child is abused (hypothetically) by: 1) an adult relative 2) an adult non- relative 3) a spouse or partner (i.e., a case of incest). Thus, the present study examined parents' reactions, how the reactions of parents' relationship to reported perpetrator affects these reactions, and how parents' prior history …

Analysis Of The Potential For Plant Uptake Of Trichloroethylene And An Assessment Of The Relative Risk From Different Crop Types, Roy-Alan C. Agustin

Theses and Dissertations

This research expands our limited knowledge on the influence of plants on the fate and effects of trichloroethylene (TCE), providing a screening tool on which to base decisions regarding the need for actual sampling of plants. First, physicochemical properties of TCE--vapor pressure, Henry's Law constant, water solubility, octanol-water partition coefficient, molecular weight, and half-life--were screened against relationships reported in literature to evaluate TCE plant uptake potential. This screening approach indicated TCE may be transferred to plants via retention by root surfaces, root uptake and translocation, and foliar uptake. Next, the PLANTX model developed by Trapp and others was applied to …

An Investigation Of Simulated Annealing Applied To Structural Optimization Problems, Richard C. Mceachin

Theses and Dissertations

This thesis investigates the feasibility of using Simulated Annealing SA in structural optimization problems. The investigation involves solving benchmark structural optimization problems with an SA algorithm, and comparing its solutions to those found by four other optimizers. Overall, the analysis shows that SA has limited applicability in structural optimization. Two primary factors were found to adversely impact the performance of the SA algorithm in these problems. These factors are high dimensionality, and high levels of constraint. The difficulty involved in solving these problems with a random search increases exponentially with the number of dimensions. The number, and non-linearity, of the …

Risk-Taking Predispositions Among Mormon Women: Improving Communication About Health And Environmental Risks, Shelly Nicholls

Theses and Dissertations

This study measures risk-taking predisposition among a conservative religious population of women, in this instance Mormon women. Risk taking is defined as a recognition of some probability of negative consequences to an action, which can include the loss of a potential reward as well as a punishment. A risk-taking predisposition results when individuals are not risk aversive but, in fact, enjoy risk taking.

Survey research collected at two conferences in Utah reveal the likelihood of moderate levels of rebellious and adventurous risk-taking predisposition among the over 500 Mormon women respondents. It is suggested that religious affiliation or economic and educational …
