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

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.

Estimation Of Electrode Kinetic Parameters Of The Lithium/Thionyl Chloride Cell Using A Mathematical Model, T. I. Evans, Ralph E. White

Faculty Publications

A one-dimensional mathematical model for the lithium/thionyl chloride primary cell is used in conjunction with a parameter estimation technique, in order to estimate the electrode kinetic parameters of this electrochemical system. The electrode kinetic parameters include the anodic transfer coefficient and exchange current density of the lithium oxidation, _a,1 and i_0,1,ref; the cathodic transfer coefficient and the effective exchange current density of the thionyl chloride reduction, _c,4 and a⁰i_0,4,ref, and a morphology parameter, . The parameter estimation is performed on simulated data first in order to gain confidence in the method. Data reported in …

A Mathematical Model Of A Lithium/Thionyl Chloride Primary Cell, T. I. Evans, T. V. Nguyen, Ralph E. White

Faculty Publications

A one-dimensional mathematical model for the lithium/thionyl chloride primary cell has been developed to investigate methods of improving its performance and safety. The model includes many of the components of a typical lithium/thionyl chloride cell such as the porous lithium chloride film which forms on the lithium anode surface. The governing equations are formulated from fundamental conservation laws using porous electrode theory and concentrated solution theory. The model is used to predict one-dimensional, time dependent profiles of concentration, porosity, current, and potentialas well as cell temperature and voltage. When a certain discharge rate is required, the model can be used …

A Thermal Analysis Of A Spirally Wound Battery Using A Simple Mathematical Model, T. I. Evans, Ralph E. White

Faculty Publications

A two-dimensional thermal model for spirally wound batteries has been developed. The governing equation of the model is the energy balance. Convective and insulated boundary conditions are used, and the equations are solved using a finite element code called TOPAZ2D. The finite element mesh is generated using a preprocessor to TOPAZ2D called MAZE. The model is used to estimate temperature profiles within a spirally wound D-size cell. The model is applied to the lithium/thionyl chloride cell because of the thermal management problems that this cell exhibits. Simplified one-dimensional models are presented that can be used to predict best and worst …

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

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.

Executive Loans From Corporate Funds, Jayne W. Barnard

Faculty Publications

The author surveys the laws affecting loans made by a corporation to its executives, including the state loan enabling statutes, the applicable tax laws, and any disclosurerequirements. Also discussed is the applicability of Regulation G to loans made by a corporation to facilitate share purchases by its executives. Finally, the author enumerates the risks inherent in executive lending and makes suggestions for risk minimization.

An Incentive-Based Wild Horse Management System On Public Rangeland, Ray G. Huffaker, James E. Wilen, B. Gardner Delworth

Faculty Publications

This paper explores an incentive-based management system to induce federal grazing permittees to choose sustained cattle stocking strategies which accommodate government-set wild horse numbers and nongrazing uses. Particular attention is paid to constraints imposed by federal grazing statutes. The proposed system employs increased livestock grazing fees to induce permittees to provide increased vegetation for consumption by wild horses and nongrazing uses. The negative impact of increased fees on permittee wealth is counterbalanced with compensatory transfer payments. Taken together, grazing fees and compensation payments induce multiple-use compliance by permittee-stewards and keep their discounted livestock profits intact at some predetermined level.

Creating A Shared History: Serial Narratives In The Young Woman's Journal, 1889-1894, Sherry Baker

Faculty Publications

"Creating a Shared History: Serial Narratives in The Young Woman's Journal, 1889-1894" is a cultural press history and textual analysis of contemporary indigenous serial literature in a nineteenth-century Mormon young women's periodical. It tests press historian Catherine Covert's assertions that some of the functions of the press are (1) to be a conservator of values, and (2) to engender harmony and affiliation among community members. The investigator places the Journal within the historical/ cultural context from which it was written, and identifies specific messages in the serial narratives that encouraged the preservation of Mormon values and Mormon community affiliation. The …

Removing Impediments To Water Markets, B. Delworth Gardner

Faculty Publications

A few years ago it was mostly economists, notably those of a libertarian stripe who were advocating voluntary market exchanges of water in the West. Now these exchanges, or transfers as they are sometimes referred to, are being unabashedly recommended by water users, politicians, bureaucrats, and even environmental organizations, who have come to see their value for achieving a more efficient water allocation. Water markets are an idea whose time has finally arrived.

Modeling Wetland Loss In Coastal Louisiana: Geology, Geography, And Human Modifications, James H. Cowan Jr., R. Eugene Turner

Faculty Publications

Habitat change in coastal Louisiana from 1955/6 to 1978 was analyzed to determine the influence of geological and man-made changes on landscape patterns within 7.5 min quadrangle maps. Three quantitative analyses were used: principal components analysis, multiple regression analysis, and cluster analysis.

Regional differences in land loss rates reflect variations in geology and the deltaic growth/decay cycles, man-induced changes in hydrology (principally canal dredging and spoil banking), and land-use changes (principally urbanization and agricultural expansion). The coastal zone is not homogeneous with respect to these variables and the interaction between causal factors leading to wetland loss is therefore locally variable …

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

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 …

Regional Security Organizations And National Interests: Analyzing The Nato-Greek Relationship, Constantine P. Danopoulos

Faculty Publications

This article analyzes the reasons which account for Greece's continuing membership in the Atlantic Alliance, even though NATO has not lived up to expectations and has failed to protect the nation's security against threats from Turkey. Following a brief examination of Greek attitudes toward NATO and the nature of dissatisfaction, the article argues that strategic concerns are, at best, of secondary importance. Instead, Greece's continuing membership in the Alliance is a result of the nation's economic ties to the West and the dependency of its military on NATO and Washington for advanced training, arms, war materiel, and other professional considerations. …

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.
