High Recovery Desalting Of Brackish Water By Electrodialysis: Field Tests At Yuma Desalting Test Facility & At La Verkin Springs, United States Department Of The Interior, Bureau Of Reclamation

Water

An ED (electrodialysis pilot plant achieved high desalting recoveries of nearly 95 percent at the YDTF (Yuma Desalting Test Facility, Arizona) and 92 percent at LVS (La Verkin Springs, Utah) during over 4000 hours of operation. Brine TDS (total dissolved solids) concentrations of nearly 100 000 g/m³ were obtained at LVS, which is a greater brine concentration than is possible using RO (reverse osmosis). The LVS required ED energy (while producing a product TDS concentration of about 1000 g/m³) is estimated to be about one-third the energy requirements of a commercially available distillation brine concentrator. Lowering product …

Keynote Address—Politics Of Pesticides, David H. Dietz

Vertebrate Pest Conference Proceedings: 11th (1984)

The politics of pesticides is a rather humorless topic, as I'm sure most of you know. I've always been told that when you start an address or make a speech you ought to have some kind of humor, if for no other reason that you at least get your audience to listen to you for two minutes during any presen-tation. For those of you that may be members of the Audubon Society or members of the Sierra Club, I'll, in advance, make my apologies for the joke I'm about to tell. It's not really meant as a put down if …

Rat Control In Alberta, Michael J. Dorrance

Vertebrate Pest Conference Proceedings: 11th (1984)

A rat control program, administered and coordinated by Alberta Department of Agriculture, has kept Alberta essentially free of Norway rats (Rattus norvegicus) since 1950. A control zone, 29 x 600 km, along the eastern border prevents rats from moving into Alberta from the east. Sporadic rat infestations within the interior of Alberta are reported by concerned citizens and eradicated by government personnel. Strong support for the program by citizens and local governments was developed through public education and information. The program has been successful for a variety of reasons including geography, climate, legislation, availability of warfarin, the relatively …

Finite Element Simulation Of Saturated-Unsaturated Subsurface Flow, George E. Blandford

KWRRI Research Reports

A two-dimensional transient model for flow through saturated-unsaturated porous media is developed, The model numerically solves the pressure head dependent or moisture content dependent form of Richard's equation. The model code uses isoparametric quadratic triangular and/or quadrilateral finite elements for the geometric representation and for the weak Galerkin spacial integrations. An implicit, unconditionally stable single-step numerical time integration scheme with an oscilliatory noise reduction option is utilized for the temporal discretization. The highly efficient symmetric skyline (profile) solution scheme is used to solve the resulting simultaneous equations. The nonlinear subsurface flow parameters are approximated using cubic spline interpolation. The element …

Bags Vs. Strings: Hadrons In Type I And Type Ii Superconducting Vacua, V. Parameswaran Nair, C. Rosenzweig

Publications and Research

Two popular models for hadronic structure are bags and strings. Both involve analogies with superconductivity. We claim that the most appropriate analogies are type I superconductors for bags and type II superconductors for strings. The structures of hadrons is somewhat different for the two situations. In principle, and in practice in the real world, it is the similarities which are most important. These include linear confining potentials, linearly rising Regge trajectories and short distance Coulomb potentials. These are all generic properties of bound states in a superconductor and the main distinctions between bags and strings is under what circumstances these …

Magnetosome Dynamics In Magnetotactic Bacteria, S. Ofer, I. Nowik, E. R. Bauminger, G. C. Papaefthymiou, Richard B. Frankel, Richad P. Blakemore

Physics

Diffusive motions of the magnetosomes (enveloped Fe₃O₄ particles) in the magnetotactic bacterium Aquaspirillum magnetotacticum result in a very broad-line Mössbauer spectrum (T ~ 100 mm/s) above freezing temperatures. The line width increases with increasing temperature. The data are analyzed using a bounded diffusion model to yield the rotational and translational motions of the magnetosomes as well as the effective viscosity of the material surrounding the magnetosomes. The results are <θ²>^l/2 < 1.5° and <x²>^1/2 < 8.4 Å for the rotational and translational motions, respectively, implying that the particles are fixed in whole cells. The effective viscosity is 10 cP at 295 K and increases with decreasing temperature. Additional Fe³⁺ material in the cell is shown to be associated with the magnetosomes. Fe²⁺ material in the cell appears to be …

Research Note: Pcbs In The Acushnet River Estuary, Jacek Sulanowski

Bridgewater Review

Much media attention has recently been devoted to potentially toxic substances disseminated throughout various components of the environment. In almost every case these substances had been manufactured and distributed under the assumption that they did not pose a threat to man. Indeed when tested by methods current at the time of their initial introduction the substances were considered benign. It was only later when technologically advanced and more sensitive methods of analyses were developed that the presence of these substances was considered to be of real concern. Unfortunately, in the interval between introduction and detection, the accumulation of these substances …

Inverting The Ratio Of The Complex Parallel And Perpendicular Reflection Coefficients Of An Absorbing Substrate Using A Transparent Thin-Film Coating, R. M.A. Azzam

Electrical Engineering Faculty Publications

An absorbing substrate can be coated with a transparent thin film of refractive index N₁ (within a certain range) and thickness d such that the ratio of complex reflection coefficients for the p_and s polarizations of the film-covered substrate ρ = R_p/R_s is the inverse of that of the film-free substrate ρ¯ = R¯_p/R¯_s at an angle of incidence ø. A method to determine the relationship among ø, N₁, and d that inverts ρ (i.e., makes ρ = 1/ρ¯) for a given substrate at a given wavelength is described and is …

Electrochemical Studies Of Antimony(Iii) And Antimony(V) In Molten Mixtures Of Aluminum Chloride And Butylpyridinium Chloride, Dhia A. Habboush, Robert A. Osteryoung

Chemistry & Physics Faculty Publications

Electrochemical studies of Sb, Sb(III), and Sb(V) have been camed out in molten mixtures of AlC13 and N-1-butylpyridinium chloride (BuPyCl) at 40 OC, as a function of melt composition. Analysis of measurements in the acidic melts indicates SbC12+ as the dominant species. The reduction of this species on glassy carbon exhibits irreversible behavior. In the basic melts, SbC14- and SbC1,- are believed to be the dominant species. The reduction of Sb(II1) to Sb on glassy carbon also showed irreversible behavior while its oxidation to Sb(W revealed a quasi-reversible behavior. No Sb(II1) oxidation was observed in the acidic melts.

Derivatives Of Trifluorovinylsulfur Pentafluoride And F-(Tert-Butyl) Hypochlorite, Jo Ann Marie Canich

Dissertations and Theses

Trifluorovinylsulfur pentafluoride dimerizes to (SF₅CFCF₂)₂ in the presence of cesium fluoride. Two derivatives of trifluorovinylsulfur pentafluoride, SF₅CF(CF₃)C(O)F and SF₅CF(CF₃)C(O)NH₂, were used to prepare the new compounds, SF₅CF(CF₃)CO₂H and SF₅CF(CF₃)CN, respectively. The first was prepared by reacting the SF₅-acid fluoride with water, while the second involved the abstraction of water from the SF₅-amide using P₄O₁₀. The attempted preparation of a bis-pentafluorosulfur ketone and a pentafluorosulfur containing acid anhydride …

High Valent Chromium (V) And Chromium (Vi) Complexes, Harry Bennett Davis

Dissertations and Theses

A new preparative route to the only neutral chromium(V) oxide fluoride, chromium oxide trifluoride, has been accomplished by the reaction of xenon difluoride with chromyl fluoride at high temperature. The chromium oxide trifluoride is produced as crystals which are suitable for single crystal studies. In reactions of chromium oxide trifluoride with alkali and alkaline metal fluorides in anhydrous hydrogen fluoride, new chromium(V) oxide fluoride salts were obtained; these salts were not of high purity due to unknown problems. An attempt to prepare chromium oxide tetrafluoride by the reaction of xenon difluoride with chromyl fluoride in anhydrous hydrogen fluoride failed to …

Desulfurization Of Coal Using Carboxylic Acids & Peracids, Dwight Watson

Masters Theses & Specialist Projects

Bituminous coals were desulfurized by leaching in a 325 ml, agitated, autoclave with hot, dilute solutions of carboxylic acids, buffered carboxylic acids, carboxylic salts, and carboxylic salt:alkali combinations. The partial pressure of oxygen was not increased as it was found not to increase the amount of organic sulfur removal. The effect of increasing carboxylic size and decree of desulfurization was studied. Among the carboxylic acids studied, formic acid removed the greatest amount of organic sulfur;and iso-valeric acid removed the greatest percentage of pyritic sulfur. It was found that there is a direct correlation between the amount of organic sulfur removal …

Patterns Of Earthquakes And The Effect Of Solid Earth And Ocean Load Tides At Mount St. Helens Prior To The May 18, 1980, Eruption, Stephen R. Mcnutt, R. J. Beavan

School of Geosciences Faculty and Staff Publications

Seismographs near Mount St. Helens Volcano recorded an earthquake swarm lasting nearly 2 months prior to the catastrophic May 18, 1980, eruption. The earthquakes are divided into four classes based on station CPW (Δ = 116 km) seismogram characteristics: (1) events with Sv:P amplitude ratio >3 and dominant frequency >3 Hz; (2) events with Sv:P ratio between 1 and 3 and dominant frequency >2 Hz; (3) events similar to characteristic 2 but with a strong (probably surface wave) phase just after the S phase; and (4) events with frequencies between 1 and 2 Hz lacking a clear S phase. The …

Photoaffinity Labeling Of The Antimycin Binding Site In Rhodopseudomonas Sphaeroides, Emily Wilson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to identify the site of interaction of antimycin with the ubiquinone-cytochrome b-c1 oxidoreductase in the photosynthetic bacteria, Rhodopseudomonas sphaeroides. To accomplish this goal, three areas of research were undertaken: the synthesis of a radiolabeled, photoaffinity analog of antimycin, identification of the inhibitory characteristics of this analog, and the photoaffinity labeling of the antimycin binding site. All three areas were accomplished.

The major finding of this study was the identification of an 11,000 dalton polypeptide as the predominantly labeled protein. Although this polypeptide was not exclusively labeled, it was consistently labeled and showed competition …

Group Comparability: A Multiattribute Utility Measurement Approach To The Use Of Random Assignment With Small Numbers Of Aggregated Units, C. Anderson Johnson, John W. Graham, Brian R. Flay, William B. Hansen, Linda M. Collins

CGU Faculty Publications and Research

It is not always possible, especially in large-scale evaluation research, to ensure that random assignment will produce groups that are comparable on any number of potentially important factors. Typically, gaining comparability has been achieved only at the expense of random assignment. A method is presented that allows multivariate comparability while making only minimal restrictions on randomization. The procedure is demonstrated in the context of assigning 63 aggregated units (schools) to 28 experimental and control conditions. Good comparability of groups for all primary main effects and interactions was verified for 15 individual variables.

Ixtoc I: Case Study Of A Major Oil Spill, Peter G. Myer

Marine Affairs Theses and Major Papers

The most disastrous oil spill the western hemisphere has ever witnessed occurred during the 10 months between June 1979 and March 1980, when the experimental well IXTOC I blew out off the coast of Mexico's Yucatan Peninsula. The disaster's effects on South Texas virtually destroyed a year's earnings for the region's tourism industry and cut into the profits of many commercial fishermen. The activities at the well that caused the blowout and subsequent spill, the effects of the oil on Texas' Gulf Coast, and the legal attempts to recover against losses suffered as a result of the spill will be …

Investigation Of Matrix Effects On The Furnace Atomic Absorption Signals Of Chromium, Nickel And Selenium, Susan Marie Viet

Chemistry & Biochemistry Theses & Dissertations

The flameless atomic absorption signals of chromium, nickel and selenium are subject to matrix interferences arising from inorganic salts and anions commonly found in urine. The effects of such salts on the atomic absorption signals were investigated using Polarized Zeeman Effect background correction in conjunction with a detector/readout system capable of resolving absorbance signals in 18 msec readings. Both optical temperature control and current temperature control were employed for each analysis. Peak area, peak height, peak shape and appearance time were compared for matrix-free standards and matrix-containing standards.

The influence of the inorganic salts on the metal analyses was found …

Toxic Characteristics Of Fluorocitrate, The Toxic Metabolite Of Compound 1080 , Peter J. Savarie

Vertebrate Pest Conference Proceedings: 11th (1984)

This paper reviews toxicological research involving fluorocitrate, the toxic metabolite of sodium monofluoroacetate (fluoroacetate), which is the active ingredient in the pesticide Compound 1080. Many toxicological studies have been done with fluoroacetate and the results obtained are actually due to the fluorocitrate because it has been definitely proved that, from a biochemical perspective, fluoroacetate is not toxic but fluorocitrate is. The classical explanation of the toxic action of fluorocitrate is that it inhibits the enzyme aconitase in the tricarboxylic acid cycle. Deactivation of aconitase results in decreased energy production by cells and ultimately death of the organism. However, the more …

A Weather-Resistant Tracking Board, D.S. Shepherd, J.H. Greaves

Vertebrate Pest Conference Proceedings: 11th (1984)

The main practical limitation of tracking boards for the study of small mammals is that the sensitive surface is very vulnerable to damage by rain or dew. A tracking board is described that is easily prepared for use in the field, is resistant to rain and running water, and is sensitive enough to record the footprints of mice. The literature on tracking board techniques is reviewed briefly.
