Can We Guarantee The Safety Of Genetically Engineered Organisms In The Environment?, Kathleen H. Keeler, Frances E. Sharples

School of Biological Sciences: Faculty Publications

Can we guarantee the safety of genetically engineered organisms in the environment? To anticipate my remarks, the answer to the title question is “No, we cannot guarantee the safety of genetically engineered organisms released into the environment.” Indeed, it is a tenet of the scientific method that nothing can be proved, only disproved. Thus, we can never show that a release will be safe. We could only show that it would be unsafe, if that were the case. However, if the question is posed differently, for example, can we safely release genetically engineered organisms into the environment?, the answer is …

Human Health Effects Assays, Ronald C. Sims, J. L. Sims, R. R. Dupont

Biological Engineering Faculty Publications

Environmental health risk assessments based upon animal study results, epidemiology, quantitative structure activity relationships (QSARs), dose-response relationships, risk perception, and expert systems approaches, and the evaluation of mechanisms of carcinogenesis represent the focus for 1987. The term "biological risk assessment" was discussed by Clayson¹ to describe that part of risk assessment concerned with the relevance of specific animal results to the induction of human cancer. Guidelines for health assessment of suspect developmental toxicants addressed evaluation of data from animal testing studies.² Animal toxicity data on 200 chemicals and epidemiologic data on 30 chemicals was included within a data …

An Analysis Of The Abaca Natural Fiber In Reinforcing Concrete Composites As A Construction Material In Developing Countries, Rolando V. Magdamo

Dissertations and Theses @ UNI

This study was undertaken to analyze the flexural and splitting tensile strengths and the ductility of abaca fiber-reinforced concrete composites. Abaca fibers are natural fibers of vegetable origin prepared from the abaca plant which is a native plant of the Philippine Islands. The purpose of the study was to investigate how various volume-fractions of the abaca fiber in the concrete mix could affect the mechanical properties of the concrete matrix.

A concrete design mix containing a volume ratio of 1.0 part Type I Portland...cernent and 3.0 parts sand was utilized in the preparation of laboratory test samples. Abaca fibers were …

Nebraska's Modified-Open-Front Farrowing Houses Design And Operation, Gerald R. Bodman, Donald G. Levis, Duane E. Reese

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Two modified-open-front non-mechanically ventilated farrowing houses with creep boxes were operated over a two year period. Annual energy requirements were in the range of 10.6 to 10.9 cents per crate per day. No adverse effects on pig performance were realized. In most instances pig performance exceeded national standards of excellent performance—survival rates in excess of 90% and 21-day pig weights of 5.9 to 6.8 kg (13 to 15 lb). The study verified that another alternative is available to producers who do not want additional mechanical equipment to operate and maintain.

A Theory Of Lexical Semantics, William C. Purdy

Electrical Engineering and Computer Science - All Scholarship

The linguistic theory of Richard Montague (variously referred to as Montague Grammar or Montague Semantics) provides a comprehensive formalized account of natural language semantics. It appears to be particularly applicable to the problem of natural language understanding by computer systems. However the theory does not deal with meaning at the lexical level. With few exceptions, lexical items are treated simply as unanalyzed basic expressions. As a result, comparison of distinct lexical meanings or of semantic expressions containing these lexical meanings falls outside the theory. In this paper, I attempt to provide a compatible compatible theory of lexical semantics which may …

Approaches To The Synthesis Of Dentin Bonding Agents Containing Vinyl And Carbamate Functional Groups, Steven W. Amato

Theses

The synthesis of four new monomers containing vinyl and carbamate functional groups was attempted. The desired products were N-m-methacryloxyphenyl-O-phenyl carbamate, N-p-methacryloxy-O-phenyl carbamate, m-N-phenylcarbamato-2-methacryloxyethoxy benzoate, and p-N-phenylcarbamato-2-methacryloxyethoxy benzoate. The carbamate functional group was derived by the Lewis Acid catalyzed reaction of meta-aminophenol, para-aminophenol, meta-aminobenzoic acid, and para-aminobenzoic acid with diphenyl carbonate. The vinyl function was derived, in the case of the aminophenols, by reaction with methacrylyl chloride, and in the case of the aminobenzoic acids, with 2-hydroxyethyl methacrylate.

Partial products only were prepared, these being the two carbamate functional phenols, the two carbamate functional benzoic acids, the two methacryloxy functional derivatives …

The Relationship Between Linguistic And Image Based Learning Approaches For Complex Problem Solving: A Case For Computer Generated Animation In Instructional Presentation Of Complex Technical Processes, Stanley T. Bissinger

Graduate Research Papers

The purpose of this study is to provide a rationale for development of new approaches to educating students about complex technical processes. This study may also prove helpful for determining what type of technical content is better suited for computer animated presentation.

Nucleation And Growth Of Zinc Electrodeposited From Acidic Zinc Solutions, A. C. Beshore, B. J. Flori, G. Schade, Thomas J. O'Keefe

Materials Science and Engineering Faculty Research & Creative Works

The nucleation and initial crystal growth kinetics by electrodeposition from acidic zinc solutions was studied in the absence and presence of antimony and glue on a glassy carbon electrode. Zinc exhibits instantaneous nucleation under the experimental conditions employed in the potential region from -1600 to -2000 mV (mercurous sulphate reference). At low overpotentials antimony and glue increase the number of nuclei. © 1987 Chapman and Hall Ltd.

Expert Potentiometric Surface Modification For Groundwater Contaminant Management, R. L. Ward, Richard C. Peralta, J. R. Brashar

Civil and Environmental Engineering Faculty Publications

An expert system is linked to an previously reported optimization program. The expert system prompts the user for information about a groundwater contamination problem. The expert system determines whether pumping is a suitable containment strategy. If appropriate. it selects several well arrangements to be evaluated by an optimization algorithm.

Agenda: Water As A Public Resource: Emerging Rights And Obligations, University Of Colorado Boulder. Natural Resources Law Center

Water as a Public Resource: Emerging Rights and Obligations (Summer Conference, June 1-3)

Conference organizers and/or faculty included University of Colorado School of Law professors Lawrence J. MacDonnell, David H. Getches, and Charles F. Wilkinson.

This conference focused on the legal rights associated with a broad range of public uses and interests in water including recreation, fish and wildlife protection, and water quality. Evolving legal areas such as the public trust doctrine, instream flow laws, federal reserved rights, and wetlands protection were discussed.

Water as a Public Resource: Emerging Rights and Obligations considered the extension of the public trust doctrine to areas previously not covered by this concept, as well as developments in …
