Confronting The Earth Spirit: Humans And Nature In The Universe Story, Eugene R. August

University of Dayton Review

Ever since the topic of this year's symposium was announced as "Humans and Nature," I have felt an increasing empathy with old Dr. Faust in Goethe's drama Faust.

How Theodore Roosevelt Began The Salvation Of The Earth, Francis J. Henninger

University of Dayton Review

Though he himself would have enjoyed and perhaps sanctioned the title of this article, it is somewhat exaggerated. We know of peoples whose respect for earth makes them models for us of the kinds of conceptualization of our natural resources that we must strengthen and propagate if we are to increase the probability that this planet will be hospitable and adequate to our descendants. Those people existed long before Roosevelt. Even in his own day others (whom Roosevelt would himself have pointed to) worked hard to alert their fellow humans to the dangers of resource waste, abuse and overuse. Nevertheless, …

Aberrant Communication And Protein Kinase C In Experimental Autoimmune Thyroiditis, Joyce P. Lazarus

Loma Linda University Electronic Theses, Dissertations & Projects

Autoimmune diseases are a worldwide healthcare concern. Research has focused mainly on the role of the immune system and genetic susceptibility to autoimmune disease. However, this study investigates altered target tissue properties and their contributions to the pathogenesis of induced autoimmune thyroiditis in Lewis rats. Our hypothesis was; inflammation-induced lymphocytic infiltration and subsequent fibrosis results in physical disruption of gap junctional communication in the target tissue contributing to the disease process. Our study of intercellular communication in experimentally-induced autoimmune thyroiditis (EAT) in Lewis rats revealed a deficiency in connexin expression, connexin assembly and dye transfer [(results corroborated in murine model …

Subregional Planning In The San Francisco Bay Area: Tri-Valley Subregional Planning Strategy, Hing Wong

Master's Projects

Many people in the San Francisco Bay Area have noticed that their quality of life has deteriorated in recent years. Citizens are becoming increasingly aware of problems such as traffic congestion; cost and supply of housing; loss of open space and agricultural land; environmental concerns; deterioration of infrastructure; and economic uncertainties.

All of these problems have significant effects on the physical and social welfare of our communities. Many of them are interrelated, and the result of haphazard regional growth patterns. The real dilemma is not that these conditions exist, but that they are largely unresolvable by our present structure of …

The Redox State Of The [2fe-2s] Clusters In Soxr Protein Regulates Its Activity As A Transcription Factor, Huangen Ding, Elena Hidalgo, Bruce Demple

Faculty Publications

SoxR protein is a redox-responsive transcription factor that governs a regulon of oxidative stress and antibiotic resistance genes in Escherichia coli. Purified SoxR contains oxidized [2Fe-2S] clusters and stimulates in vitro transcription of its target gene soxS up to 100-fold. SoxR transcriptional activity, but not DNA binding, is completely dependent on the [2Fe-2S] clusters; apo-SoxR prepared in vitro binds the soxS promoter with unchanged affinity but does not have transcription activity. Thus, modulation of the SoxR [2Fe-2S] clusters was proposed to control the protein's function in transcription. Here, we provide evidence that SoxR with reduced [2Fe-2S] clusters is inactive. Redox …

Micronutrients And The Risk Of Colorectal Adenomas, Marilyn Tseng, Sharon C. Murray, Lawrence L. Kupper, Robert S. Sandler

Kinesiology and Public Health

Recent studies suggest that micronutrients, especially folate, calcium, iron, and antioxidant vitamins, affect the risk of colorectal neoplasia. The objective of this case-control study was to examine the association between these micronutrients and the risk of colorectal adenomas. The study was based on 236 cases with adenomatous polyps or cancer and 409 controls, all colonoscopy patients at University of North Carolina Hospitals between July 1988 and March 1991. After colonoscopy, subjects were interviewed using a semi-quantitative food frequency questionnaire, and average daily nutrient intakes were calculated. Sex-specific odds ratios relative to the lowest quartile of intake for each micronutrient were …

Writers On Organizations By D. S. Pugh And D. J. Hickson. Sage Publications, 1996., Abhoy K Ojha

IIMB Management Review

Derek S. Pugh and David J. Hickson, the authors of the fifth edition ,both very prominent contributors to the field in their own right, have presented, very lucidly, the current state of knowledge on organisations. They have included new topics (and writers) that have grown in importance since the last edition was published in 1989, updated some old topics and excluded those that in their opinion, have become less relevant to current debates on organisations.

Use Of Embedded Wireless Networks Within Instrumentation Products: Analysis And Performance Mapping Of A Distributed System, Behzad Parvahan

Master's Projects

Traditional instrumentation systems can be categorized into two groups: generic and custom systems. The former are standard, off-the-shelf machines, while the latter consist of specialty systems which perform target-specific tasks. While it is difficult to accurately characterize these specialty systems as a group (due to the varied nature of their functions), the standard machines are generally single units that provide limited customization and mobility.

This report explores the feasibility of a system that maintains the functionality of standard test equipment, while adding a scaleable, mobile, distributed architecture that reduces size, subsystem power consumption, and ultimately overall cost when compared to …

New Enantioselective Lewis Acid Catalysts, Mustafa Guzel

All Theses

Recently, many organic chemists have been ultimately interested in research in the synthesis of enantiomerically pure organics which are useful to synthesis of biologically active agents and prodrug substances. In the past decades, the new concepts in catalyst design unexpectedly explored the direction of natural product synthesis. In many cases, using enantioselective catalysts are the most suitable and efficient method into enantiopure systems.

Analysis Of Linkage-Friendly Genetic Algorithms, Laurence D. Merkle

Theses and Dissertations

Evolutionary algorithms (EAs) are stochastic population-based algorithms inspired by the natural processes of selection, mutation, and recombination. EAs are often employed as optimum seeking techniques. A formal framework for EAs is proposed, in which evolutionary operators are viewed as mappings from parameter spaces to spaces of random functions. Formal definitions within this framework capture the distinguishing characteristics of the classes of recombination, mutation, and selection operators. EAs which use strictly invariant selection operators and order invariant representation schemes comprise the class of linkage-friendly genetic algorithms (lfGAs). Fast messy genetic algorithms (fmGAs) are lfGAs which use binary tournament selection (BTS) with …

Multidisciplinary And Multiobjective Optimization In Conceptual Design For Mixed-Stream Turbofan Engines, Luc J. J. P. Nadon

Theses and Dissertations

Despite major advances in design tools such as engine cycle analysis software and computer aided design, conceptual gas turbine engine design is essentially a trial-and-error process based on the experience of engineers. Modern optimization concepts, such as multidisciplinary optimization (MDO), and multiobjective optimization (MOO), linked with sequential quadratic programming (SQP) methods and genetic algorithms (GA), were applied to the conceptual engine design process to automate the conceptual design phase. Robust integrated computer codes were created to find the optimal values of eight engine parameters in order to minimize fuel usage, aircraft cost and engine annulus area over a given mission. …

Refined Genetic Algorithms For Polypeptide Structure Prediction, Charles E. Kaiser Jr.

Theses and Dissertations

Accurate and reliable prediction of macromolecular structures has eluded researchers for nearly 40 years. Prediction via energy minimization assumes the native conformation has the globally minimal energy potential. An exhaustive search is impossible since for molecules of normal size, the size of the search space exceeds the size of the universe. Domain knowledge sources, such as the Brookhaven PDB can be mined for constraints to limit the search space. Genetic algorithms (GAs) are stochastic, population based, search algorithms of polynomial (P) time complexity that can produce semi-optimal solutions for problems of nondeterministic polynomial (NP) time complexity such as PSP. Three …

An Approach To Evaluate Software Effectiveness, Timothy J. Schalick

Theses and Dissertations

The Air Force Operational Test and Evaluation Center (AFOTEC) is tasked with the evaluation of operational effectiveness of new systems for the Air Force. Currently, the software analysis team within AFOTEC has no methodology to directly address the effectiveness of the software portion of these new systems. This research develops a working definition for software effectiveness, then outlines an approach to evaluate software effectiveness-- the Software Effectiveness Traceability Approach (SETA). Effectiveness is defined as the degree to which the software requirements are satisfied and is therefore application-independent. With SETA, requirements satisfaction is measured by the "degree of traceability" throughout the …

Neural Network Classification Of Environmental Samples, Jeffrey L. Blackmon

Theses and Dissertations

This research develops a general methodology for designing neural network classifiers for real-world environmental problems. This methodology is demonstrated through the design of a multi-layer perceptron to classify stainless steel and actinide samples. Neural networks, sometimes called artificial neural networks, have been shown capable of classifying complex patterns. Artificial neural networks are physiologically motivated computer algorithms which attempt to mimic the function of the large interconnected network of neurons in the human brain, which has extraordinary pattern recognition capabilities. These artificial neural networks learn to map a set of input features, elemental composition, onto a set of outputs such as …

Investigation Of Sorption Mass Transfer Models Using Synthetic Soils, Karla K. Mika

Theses and Dissertations

Grain-scale sorption mass transfer is an important process that must be considered when predicting clean-up time and choosing remediation techniques for subsurface hazardous waste contamination. Rate-limited sorption is responsible for the rebound effect, where remediated groundwater is recontaminated by desorption. Sorbed contaminants are not available for microbial degradation, and the desorption rate may govern the effectiveness of natural attenuation by biodegradation. Grain-scale sorption nonequilibrium is generally attributed to diffusive transport, either in SOM or in mineral micropores. Typically used sorption mass transfer models either fail to reproduce long-term slow desorption (first-order models), or are based on diffusion in assumed (often …
