Characterization Of The Aquatic Environment In Lake Mead Near The Proposed Spring Canyon Pumped-Storage Project, And Assessment Of Potential Aquatic Impacts, Charles R. Liston, Stephen J. Grabowski, Bureau Of Reclamation

Publications (WR)

A pumped storage system consists of an upper reservoir and lower reservoir separated by an elevation difference. During low demand energy periods such as nights and weekends water is pumped from the lower to the upper reservoir using available energy from conventional steam electric power plants. During high energy demand periods, such as mornings and afternoons of weekdays, upper reservoir water is allowed to drop back down through the same system of water conduits and turbines, generating electricity to conveniently meet abrupt electrical energy requirements. The same water turbines thus act both as pumps and as conventional hydroelectric turbines. Because …

Callianassa Trilobata (Crustacea: Thalassinidea) Influences Abundance Of Meiofauna And Biomass, Composition, And Physiologic State Of Microbial Communities Within Its Burrow, Fred C. Dobbs, James B. Guckert

OES Faculty Publications

Biochemical and traditional methods were used to determine the influence of Callianassa trilobata on microbiological and meiofaunal communities within its large, highly consolidated burrow. Sediment was collected from the lining of the shrimp's burrow, the burrow matrix, and ambient, subsurface sediment. The lining and matrix were composed of poorly sorted, fine-grained material compared to sandy ambient sediment. Meiofauna, predominantly nematodes, were most abundant in ambient sediment, not in the burrow as has been found for other species of macrofauna. Concentrations of chlorophyll a were very high in the lining, consistent with the suggestion that C. trilobata lines its burrow walls …

Preconcentration And Direct Flame Ionization Method For Measurement Of Non-Methane Organic Compounds In Ambient Air And Statistical Analysis Of Experimental Data, Lianyi Zuo

Theses

A fast and reliable method for the determination of non-methane organic compounds (NMOC) in ambient air has been developed. Samples are collected in SUMMA polished stainless steel canisters using a sampling system with a critical orifice as flowrate controller. Analysis of NMOC in the atmosphere via a canister is carried out by cryogenic preconcentration and a direct flame ionization detection method (PDFID). This system is sensitive and provides accurate measurement of ambient NMOC concentration even if the concentration is as low as 0.1 ppm carbon. The performance of the method was characterized using 19 pairs of canister samples and tested …

Detection And Determination Of N-Nitrosohexamethyleneimine In Benzenesulfonamide, N-[[(Hexahydro-1-H Azepin-1-Yl)Amino]-Carbonyl]-4 Methyl By Hptlc, Anulfo A. Valdez

Theses

A simple method, by High Performance Thin Layer Chromatography HPTLC), was developed for rapid determination of N-Nitrosohexamethyleneimine in Benzenesulfonamide, N-[((hexahydro-1 H Azepin-1-yl)amino]-Carbonyl]-4 methyl, (Tolazamide). Separation of N-Nitrosohe-xamethyleneimine from a Tolazamide solution in chloroform was obtained by precipitation of Tolazamide with n-heptane and by passing the resulting clear solution through a small silica column which was eluted with methanol.

Determination of the N-nitroso compound was achieved by ultraviolet irradiation of it on activated High Performance Silica Gel Plates. Detection was performed by spraying the plates with triethylamine and fluorescamine reagent giving a fluorescent product. Visual detection limits of 25 ppb were …

Microbial Phenol Degradation Utilizing A Complete-Mix Biological Reactor : The Effects Of Dissolved Oxygen Content, Keith Kollar

Theses

Experiments were conducted using phenol as a sole carbon source in a series of completely mixed biological reactors with solids recycle (CMBR). The reactor working volume was 4 liters, and solids were recycled from 3 liter clarifiers. Dissolved oxygen concentration (DO) was varied in order to determine the impact of this important variable on system operability.

Phenol was removed at better than 99 percent efficiency during most of the runs. Filamentous growth was not observed during any run. However, bulking did occur at higher DO levels, which was the result of microbial slime production.

A New Hazardous Waste Treatment Technology Utilizing Low Power Density Microwave Energy, Gabriele Else Windgasse

Theses

Two major applications of a new hazardous waste treatment technology using low power density microwave energy have been characterized: 1) Desorption of organic materials such as: trichloro-ethylene, para-xylene, naphthalene and gasoline hydrocarbons from substrates such as: sand and granulated activated carbon was achieved by microwave induced steam distillation and the application of a new phenomenon: arcing between GAC particles when they are exposed to microwave radiation. All contaminants could be removed to 100% (non-detectable with GC and GC-MS). 2) Decomposition of organic contaminants such as: trichloro-ethylene and trichloro-ethane in arcing/heating GAC beds. A new fluidized bed reactor ("RDW-reactor", after Ray, …

Diet, Parasitism, And Anemia In The Prehistoric Southwest, Karl J. Reinhard

School of Natural Resources: Faculty Publications

The primary goal of this study is the demonstration of the utility of parasitological data retrieved from coprolites in documenting prehistoric infectious disease. The study focuses on levels of infection of two subsistence types, hunting-gathering and agriculture. Analysis of differences between the two types, and of variation of parasitism between sites of the same type, are presented. It is demonstrated that parasitism was more common among hunter-gatherers than agricultural populations. Parasitism is shown to have been mediated by ecology and human behavior among agricultural sites.

A second goal is the integration of parasitological data with evidence of pathology derived from …

Use Of Economic Instruments In Biodiversity Conservation Projects: The Sustainability Of Projects In The Ecuadorian Amazon, Amy Lyons

Honors Theses

Under what conditions do biodiversity conservation projects that use economic incentives promote the most significant and sustainable biodiversity protection? The study of how nations can best invest their resources to promote conservation while simultaneously encouraging a sustainable form of economic development has recently become a major focus for ecologically rich, less-developed countries. There have been many innovative and successful attempts at combining biodiversity protection with economic development, and others that have done more harm than good. Since there is no guaranteed recipe for a successful project, it is crucial to examine projects in detail to discern which type of project …

Hylleraas Variational Perturbation Theory: Application To Correlation Problems In Molecular Systems, Robert J. Cave, Ernest R. Davidson

All HMC Faculty Publications and Research

Hylleraas variational perturbation theory is applied through second order in energy to estimate the correlation energy in several molecular systems. The specific choices for H₀ and V which are made lead to equations nearly identical to the multireference linearized coupled‐cluster method of Laidig and Bartlett. The results obtained are in virtually exact agreement where comparisons have been made. Results from test calculations are presented for BeH₂, CH₂, and C₂H₄. In addition, the utility of perturbation theory for selecting correlating configurations is examined. This procedure is found to be quite accurate while …

A Cytochemical Study Of The Transcriptional And Translational Regulation Of Nuclear Transition Protein 1 (Tp1), A Major Chromosomal Protein Of Mammalian Spermatids, Mohammad A. Heidaran, Richard M. Showman, Wilson Stephen Kistler

Faculty Publications

Immunocytochemical localization and in situ hybridization techniques were used to investigate the presence of spermatid nuclear transition protein 1 (TP1) and its mRNA during the various stages of spermatogenesis in the rat. A specific antiserum to TP1 was raised in a rabbit and used to show that TP1 is immunologically crossreactive among many mammals including humans. During spermatogenesis the protein appears in spermatids as they progress from step 12 to step 13, a period in which nuclear condensation is underway. The protein is lost during step 15. An asymmetric RNA probe generated from a TP1 cDNA clone identified TP1 mRNA …

1-Acyldihydropyridones As Synthetic Intermediates, Michael Andrew Foley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The most efficient and stereoselective total synthesis of (+/-)- lausbine II to date has been achieved. The key steps in this are the copper-mediated conjugate addition reaction of the Grignard reagent of 1-bromo-4-chlorobutane to a dihydropyridone and a stereoselective reduction of a quinolizidinone.

Methodology has been developed for the convenient synthesis of 1-acyl-2-substituted-1,2,5,6-tetrahydropyridines. This was accomplished by adding novel alkylzinc iodides to the 1-acyliminium ion derived from N-phenoxycarbonyl-4-methoxy-1,2,3,4-tetrahydropyridine.

Structure-Activity Relationships Of Retinoids In Developmental Toxicology, W. Brian Howard

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The teratogenic potency of retinoid analogs was determined in Syrian hamsters and compared to the teratogenic potency of all-trans-retinoic acid (all-trans-RA, ED₅₀ = 10.5 mg/kg). A total of 15 analogs having variations in the cyclohexene ring were evaluated following various amounts of single oral doses on day 8 of gestation. Retinoids containing a five- or six-membered ring were as teratogenic as all-trans-RA, provided they had sufficient lipophilic substituents on the ring. The same pattern emerged for retinoids that had six-membered aromatic ring substitution for the natural cyclohexene ring of vitamin A. Incorporation of a supplementary …

Overall Life Satisfaction Of Ileostomates: Conventional Brooke Ileostomy Versus Modified Kock Pouch, Sandra Sisson Briscoe

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this thesis is to analyze various aspects of quality of life and to determine if there is a difference in quality of life offered by a conventional ileostomy versus a continent ileostomy.

An instrument was developed to measure several factors thought to influence quality of life as well as several structural/demographic variables. This instrument was designed for persons with a conventional ileostomy and was modified for persons who had undergone conversion surgery from conventional to continent ileostomy.

Analysis of variance was performed to determine differences in quality of life for persons with a conventional, conversion, or original …

Synthetic Studies Toward Key Portions Of The Didemnins, Ok-Soon Kim

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Three different synthetic approaches toward N-[(2SR, 4S) - 4-hydroxy-2,5-dimethyl-3-oxohexanoyl]-Lleucine methyl esters were carried out by use of i) aldol condensation and amination ii) Claisen condensation and soft acid coupling reaction iii) methylation of Hia-Leu derivative in relatively high yields. (4S)-3-[(2SR, 4S)-2,5-Dimethyl-1,3-dioxo-4-(methoxyethoxy-methyloxy)hexyl]-4-(1-methyletheyl-2-oxazolidinone was prepared by the reaction of aldol condensation of lithium enolate of Evans' chiral auxilary in 80:20 diastereomeric ratio. A new method for the synthesis of (4S)-4-(t-butoxycarbonyl)amino-5-methyl-3-oxoheptanoic acid ethyl ester (Statone) was developed by the reaction of Boc-leucine with Meldrum's acid, followed by transesterification and decarboxylation in modest yield. Other a-amino acids also were applied to this methodology in …

Reactions Of Aqueous Chlorine In The Gastric Fluid Of The Rat, Michael Gary Nickelsen

Chemistry & Biochemistry Theses & Dissertations

Gastric fluid was recovered from Sprague-Dawley rats that had been fasted for 24 hr or 48 hr and administered 4 mL deionized water. The protein, carbohydrate and chloride ion content of the gastric fluid was determined.

When gastric fluid is chlorinated with radiolabeled chlorine to concentrations between 323 and 375 mg/L, analyzed by high performance chromatography followed by liquid scintillation counting, as much as 59% of the radiolabeled chlorine was associated with organic components of the gastric fluid.

Model studies with the aromatic amino acids and the protein pepsin showed the formation of chlorinated analogs. Two chlorinated amino acid derivatives …
