Amyotrophic Lateral Sclerosis Case-Control Study: Past Chemical Exposures And The Measurement Of The Red Blood Cell Acetylcholinesterase Reactivity In Vitro When Challenged At Various Dosages By Chlorpyrifos-Oxon, Naomi J. Bienfang

Dissertations and Theses @ UNI

The purpose of this study was to analyze the red blood cell acetylcholinesterase (RBC AChE) reactivity levels among persons with amyothropic lateral sclerosis (PALS) (cases) and their controls when challenged with the oxon form of the organophosphate insecticide chlorpyrifos. The ultimate objective was to determine if a correlation exists between the RBC AChE reactivity level and the participants' disease status and/or exposure to toxins through occupations and hobbies.

Cases in this study were individuals diagnosed by a neurologist with sporadic ALS. Controls were individuals who were not genetically related to the PALS and were neuromuscular disease free. Controls were a …

Golf Course Pollution Prevention Guide, Iowa Waste Reduction Center

Iowa Waste Reduction Center Book Gallery

According to the Environmental Protection Agency (EPA), pollution prevention can be defined as: “The use of materials, processes, or practices that reduces or eliminates the creation of pollutants or wastes at the source.” Pollution prevention represents a shift away from the old school of thought, “pollution control,” in which waste was not dealt with until after it was generated. Through pollution prevention, we look at the processes that generate the waste to see if we can avoid creating a waste in the first place, or at least reduce the hazardous nature of the waste. When this is not possible, the …

Modeling And Measuring The Dispersion Of Odors From Hog Confinements, François Béra

Dissertations and Theses @ UNI

A comparison was made between predicted and measured odor concentration downwind of two hog finishing confinements. Two Gaussian dispersion models, STINK.BAK and AERMOD, were used. The experimental cases examined odor emanating from a mechanically-ventilated facility and a curtain-sided facility during summer 2003. A field olfactometer was used to measure odor concentration. The odor concentrations served as input to STINK.BAK, which then estimated the odor emission rate from the confinement. AERMOD used this emission rate and other meteorological data to predict the peak concentration of odor around the confinement over the sampling hour. The calculated odor emission rates are slightly higher …

A Preliminary Study Of Sustainable Eco-Industrial Partnerships In The State Of Iowa, Kathleen L. Hennings

Dissertations and Theses @ UNI

The proliferation of industry around the globe, coupled with concerns about the dwindling supply of raw materials, has fostered the emergence of a new manufacturing ideology. In contrast to the linear manufacturing model, raw material in and finished product out, precision manufacturing takes waste material in and provides a new product out. Companies in this study who participated in precision manufacturing were identified as partners when one company sold or traded a waste product to a separate company who used the waste in their primary production. This study was initiated to determine the factors present in successful waste exchange partnerships …

Health Promotion Evaluation And Needs Assessment In The Transylvania Region Of Romania, Bryan C. Byrd

Dissertations and Theses @ UNI

Since the revolution of 1989, Romania has been undergoing wide ranging changes affecting all aspects of the country including health promotion. As common to many newly independent states (NIS) the changes in socio-economics, on-going poverty, unemployment status, and the overall culture shock of political transition, has resulted in health characteristics and indicators improving in some areas but suffering in others. This project was initiated as a descriptive study of the health promotion practices of Transylvania, Romania. The goal of the research was to describe and discover the philosophical practices driving current Romanian health promotion practices, as well as to conduct …

An Examination Of Environmental Sensitivity Among Supporters Of An Outdoor Recreation Area, Rodney James Blackman

Dissertations and Theses @ UNI

The environment as an issue has been prominently before the public for over three decades. Yet the question of how much people know about the natural environment and how committed they are to the environment has seldom been considered in research literature. Research of this nature is needed because without it individuals interested in the preservation and conservation of the environment cannot be sure how their efforts to increase people's environmental sensitivity should be applied. The purpose of this study was to examine the level and extent of environmental sensitivity among supporters of an outdoor recreation area/facility in northeast Iowa. …

Radon Reduction, Improvement Of Indoor Air Quality, And Energy Savings Through An Original Solar Ventilation System, Heather E. Rhoads

Dissertations and Theses @ UNI

This study evaluated the improvement of indoor air quality and energy savings achieved, by an original solar ventilation system installed at test sites exhibiting elevated radon levels. Conventional residential energy conservation measures that limit air exchange rates between the indoors and outdoors have been shown to increase concentrations of radioactive radon decay products as well as other indoor air contaminants. Growing concern about radon lung cancer risks, carbon monoxide poisoning, and the "sick building syndrome" have increased demand for improved indoor air quality. Due to added heating and cooling loads, ventilation generally incurs substantial installation and operational costs. All commercially …

The Modeling Of Phosphorus Dynamics In A Lake System, Todd N. Swift

Presidential Scholars Theses (1990 – 2006)

We have constructed a basic closed stock and flow model of lake phosphorus cycling that includes three stock concentrations: inorganic phosphorus, phosphorus in living organic material, and phosphorus in dead organic material. Stocks are connected by flows that are made stock dependent in a plausible manner. The model exhibits two equilibrium points, one stable and the other unstable, with an interesting crossover between them. Below a certain total phosphorus threshold, stable equilibrium is characterized by all of the phosphorus stock residing in the inorganic form, suggesting the collapse of the biological system. Above the threshold, this is not true. We …

Towards The Development Of A Kantian Environmental Ethic, Sally Nelson Wiedmann

Dissertations and Theses @ UNI

This thesis is a response to Aldo Leopold's 1949 call for a new, wholistic environmental ethic. Leopold's call stemmed from his concern over the increasing degradation of the environment as a result of a utilitarian approach which judges nature as good only insofar as it is good for human economic and recreational benefit. This thesis is aimed at the development of a wholistic, non-utilitarian environmental ethic grounded in the philosophy. of Immanuel Kant. The thesis begins with a brief review of the utilitarian environmental ethic which Leopold opposed and some of the consequences it has wrought in the natural world. …
