Oxygen Reduction In A Proton Exchange Membrane Test Cell, S. J. Ridge, Ralph E. White, Y. Tsou, R. N. Beaver, G. A. Eisman Jan 1989

Oxygen Reduction In A Proton Exchange Membrane Test Cell, S. J. Ridge, Ralph E. White, Y. Tsou, R. N. Beaver, G. A. Eisman

Faculty Publications

Oxygen reduction in a gas-fed porous electrode attached to a proton exchange membrane is discussed. Experimental data and a mathematical model are presented for the test cell used. Various membrane and electrode assemblies were tested at different levels of platinum loading and Teflon® content. The model accounts for the diffusion and reaction of oxygen and the diffusion and reaction of hydrogen ions. Sulfuric acid was placed above the membrane in the test cell reservoir to provide a source of protons for the reduction of oxygen at the cathode. Based upon model predictions, it is shown that the transport of the …

An Algebraic Model For A Zinc/Bromine Flow Cell, G. D. Simpson, Ralph E. White Jan 1989

An Algebraic Model For A Zinc/Bromine Flow Cell, G. D. Simpson, Ralph E. White

Faculty Publications

An algebraic model for a parallel plate, zinc/bromine flow cell is presented and used to predict various performance quantities, which are compared to those predicted by using previously published differential equation models. The results presented compare well with previous work. The model is based on the concept of using well-mixed zones and linear concentration and potential profiles for the diffusion layers and the separator. The Butler-Volmer equation is used for the electrochemical reactions, and the homogeneous reaction between bromine and bromide is included.

Unobtrusive Studies And The Quality Of Academic Library Reference Services, Jo Bell Whitlatch Jan 1989

Unobtrusive Studies And The Quality Of Academic Library Reference Services, Jo Bell Whitlatch

Faculty Publications

This article uses empirical data from a recent obtrusive study of reference performance to explore content validity and assumptions regarding unobtrusive studies. Data collected by author support the contention that improvements are highly desirable before conducting more unobtrusive studies of reference service. The two most important changes concern the development of test questions representing all types of queries and supplementing the correct fill rate with other measures of reference performance.

Union Effects On Productivity, Profits, And Growth - Has The Long Run Arrived?, John T. Addison, Barry T. Hirsch Jan 1989

Union Effects On Productivity, Profits, And Growth - Has The Long Run Arrived?, John T. Addison, Barry T. Hirsch

Faculty Publications

This article interprets literature examining union effects on economic performance. Production function studies indicate small overall union impacts on productivity; positive effects, where they exist, appear to result from management response to decreased profit expectations and from a natural selection process. Lower profitability among unionized firms is well established; more interesting is the possibility that unions appropriate quasi rents deriving from long-lived tangible and intangible capital. the connection between unions, investment behavior, and productivity growth emerges as a particularly fruitful line of empirical inquiry, although it does not encourage a sanguine view of unionism's long-run impact.

Models And Tests In Functional Morphology: The Significance Of Description And Integration, Dominique G. Homberger Dec 1988

Models And Tests In Functional Morphology: The Significance Of Description And Integration, Dominique G. Homberger

Faculty Publications

SYNOPSIS: Functional-anatomical work on complex structural systems is handicapped by several difficulties: (1) Lack of established guidelines on how to select the structures that are relevant for the intended study, (2) lack of methods to check the accuracy of the description of a system's morphology, and (3) the need to integrate a large mass of results obtained through a variety of approaches taken from different disciplines, such as anatomy, physiology, physics, biochemistry, ecology and evolutionary biology. Suggestions to alleviate some of the problems include (1) to use information on the physiological and physical properties of the tissues in a system …

The UNISOR on-line nuclear orientation facility (UNISOR/NOF) consists of a3He-4He dilution refrigerator on line to the isotope separator. Nuclei are implanted directly into a target foil which is soldered to the bottom accessed cold finger of the refrigerator. A 1.5 T superconducting magnet polarizes the ferromagnetic target foils and determines the axis of symmetry. Up to eight gamma detectors can be positioned around the refrigerator, each 9 cm from the target. A unique feature of this system is that the k=4 term in the directional distribution function can be directly and unambigously deduced so that a single solution for the …

Tomorrow's Research Library: Vigor Or Rigor Mortis?, Richard Hacken Nov 1988

Tomorrow's Research Library: Vigor Or Rigor Mortis?, Richard Hacken

Faculty Publications

The gamut of futuristic visions in library literature—from optimistic to pessimistic, from realistic to fanciful. Contradictory answers to recurring questions are found: Can we finally say goodbye to Gutenberg? Will the library card be replaced by the telephone credit card? Will book ownership give way entirely to information access. Will "books without pages" and "libraries without walls" necessarily lead to librarians without jobs? Is it possible to set timetables? After past crystal ball gazers are compared, contrasted, and critiqued, positive plans for progress are suggested.

Inulin-125I-Tyramine, An Improved Residualizing Label For Studies On Sites Of Catabolism Of Circulating Proteins, Janet L. Maxwell, John W. Baynes, Suzanne R. Thorpe Oct 1988

Inulin-125I-Tyramine, An Improved Residualizing Label For Studies On Sites Of Catabolism Of Circulating Proteins, Janet L. Maxwell, John W. Baynes, Suzanne R. Thorpe

Faculty Publications

Residualizing labels for protein, such as dilactitol-125I-tyramine (125I-DLT) and cellobiitol-125I-tyramine, have been used to identify the tissue and cellular sites of catabolism of long-lived plasma proteins, such as albumin, immunoglobulins, and lipoproteins. The radioactive degradation products formed from labeled proteins are relatively large, hydrophilic, resistant to lysosomal hydrolases, and accumulate in lysosomes in the cells involved in degradation of the carrier protein. However, the gradual loss of the catabolites from cells (t1/2 approximately 2 days) has limited the usefulness of residualizing labels in studies on longer lived proteins. We describe here a higher molecular weight (Mr approximately 5000), more efficient …

Independent Oscillator Model Of A Heat Bath: Exact Diagonalization Of The Hamiltonian, G. W. Ford, J. T. Lewis, R. F. O'Connell Oct 1988

Independent Oscillator Model Of A Heat Bath: Exact Diagonalization Of The Hamiltonian, G. W. Ford, J. T. Lewis, R. F. O'Connell

Faculty Publications

The problem of a quantum oscillator coupled to an independent-oscillator model of a heat bath is discussed. The transformation to normal coordinates is explicitly constructed using the method of Ullersma. With this transformation an alternative derivation of an exact formula for the oscillator free energy is constructed. The various contributions to the oscillator energy are calculated, with the aim of further understanding this formula. Finally, the limitations of linear coupling models, such as that used by Ullersma, are discussed in the form of some critical remarks. © 1988 Plenum Publishing Corporation.

Cutting The Loss From Federal Irrigation Water Subsidies, B. Gardner Delworth, Ray G. Huffaker Oct 1988

Cutting The Loss From Federal Irrigation Water Subsidies, B. Gardner Delworth, Ray G. Huffaker

Faculty Publications

The Bureau of Reclamation recently announced that its prime mission since 1902-building dams to make the desert bloom in the American West-is pretty much complete. While never really admitting that its newer projects have been economically infeasible, Bureau management has at last recognized that the days of the big public water project are gone. The Bureau now plans to turn its attention and resources to other more pressing problems, such as helping other agencies with construction projects needed to cope with hazardous waste.

Analysis Of The Convergence History Of Fluid Flow Through Nozzles With Shocks, Mohammad Saleem, A Cheer, M Hafez, T Pulliam Jul 1988

Analysis Of The Convergence History Of Fluid Flow Through Nozzles With Shocks, Mohammad Saleem, A Cheer, M Hafez, T Pulliam

Faculty Publications

"Convergence of iterative methods for the solution of the steady quasi-one-dimensional nozzle problem with shocks is considered. The finite-difference algorithms obtained from implicit schemes are used to approximate both the Euler and Navier-Stokes Equations. These algorithms are investigated for stability and convergence characteristics. The numerical methods are broken down into their matrix-vector components and then analyzed by examining a subset of the eigensystem using a method based on the Arnoldi process. The eigenvalues obtained by this method are accurate to within 5 digits for the largest ones and to within 2 digits for the ones smaller in magnitude compared the …

How Do Harpacticoid Grazing Rates Differ Over A Tidal Cycle? Field Verification Using Chlorophyll-Pigment Analyses, Alan W. Decho Jun 1988

How Do Harpacticoid Grazing Rates Differ Over A Tidal Cycle? Field Verification Using Chlorophyll-Pigment Analyses, Alan W. Decho

Faculty Publications

Four species of meiobenthic copepods were examined for diatom feeding. Microscopic analysis of gut-pellet contents from field-collected individuals indicated frequent ingestion of diatoms by 3 harpacticoids (Scottolana canadensis, Microarthridion littorale, Cletocamptus deitersi) while occasional diatom ingestion occurred Paronychocamptus huntsmani. Frustules were usually empty and broken, indicating that contents were digested. Laboratory experiments using 14C-labeling showed assimilation of diatoms by the 3 species examined. Field grazing rate studies were conducted over different portions of a tidal cycle using fluorescent chlorophyll-pigment analysis of gut-contents. Highest diatom consumption (p<0.05) occurred just after the mudflat became exposed (i.e. Early Low Water level, ELW) for S. canadensis, while consumption at Late Low Water …
