A Mathematical Model Of A Sealed Nickel-Cadmium Battery, Deyuan Fan, Ralph E. White Jan 1991

A Mathematical Model Of A Sealed Nickel-Cadmium Battery, Deyuan Fan, Ralph E. White

Faculty Publications

A mathematical model for the charge and discharge of a sealed nickel-cadmium (Ni-Cd) battery is presented. The model is used to study the effect of transport properties of the electrolyte and kinetic parameters of the electrode reactions on the cell performance during the charge and discharge period. The model can also be used to demonstrate the changes of cell performance during cycling. Some comparisons between model predictions and experimental results indicate that the model predictions appear to fit the experimental data well. Sensitivity analyses illustrate that the sealed nickel-cadmium battery operates under activation control. It is also shown theoretically that …

Faculty Publications

Changes in the activites of S-adcnosylmethionine (SAM) synthetase (methionine adenosyltransferase, EC 2.5.1.6.) and SAM decarboxylase (EC 4.1.1.50) were studied in carrot (Daucus carota) cell cultures in response to 2,4-dichlorophenoxyacetic acid (2,4-D) and several inhibitors of polyamine biosynthesis. Activity of SAM synthetase increased significantly during the first 5 days of culture under all conditions, maximum activity being observed in thc presence of 2,4-D. DL-α-Difluoromethylarginine (DFMA), I,L-α-difluoroinethylornithine (DFMO) and cyclohexylammonium sulfatc (CHAS) had little effect on the activity of this enzyme. The enzyme activity was lower than the controls in the presence of methylglyoxal bis(guany1hydrazone) (MGBG). The activity of SAM dccarboxylasc, which …


A Modified Electrochemical Process For The Decomposition Of Hydrogen Sulfide In An Aqueous Alkaline Solution, Z. Mao, A. Anani, Ralph E. White, S. Srinivasan, A. J. Appleby Jan 1991

A Modified Electrochemical Process For The Decomposition Of Hydrogen Sulfide In An Aqueous Alkaline Solution, Z. Mao, A. Anani, Ralph E. White, S. Srinivasan, A. J. Appleby

Faculty Publications

An electrochemical process for the decomposition of hydrogen sulfide into its constituents in an aqueous alkaline solution is presented. It essentially consists of presaturation of an alkaline scrubber solution with H2S. Thereafter, partial neutralization of the presaturated solution provides not only the necessary mass balance for electrolysis, but also creates the optimum conditions under which passivation of the anode, as well as side chemical and electrochemical reactions, are minimized. Finally, the electrolysis stage of the process leads to precipitation of crystalline sulfur at the anode and evolution of hydrogen at the cathode. Regeneration of the alkaline solution via …


In Situ Degradation Of Polyhalogenated Aromatic Hydrocarbons By Electrochemically Generated Superoxide Ions, E. E. Kalu, Ralph E. White Jan 1991

In Situ Degradation Of Polyhalogenated Aromatic Hydrocarbons By Electrochemically Generated Superoxide Ions, E. E. Kalu, Ralph E. White

Faculty Publications

The reduction of dioxygen in aprotic media yields superoxide ions which react with polyhalogenated aromatic hydrocarbons by nucleophilic substitution. The degradation of hexachlorobenzene to bicarbonates and chlorides using in situ generated superoxide ions was carried out at room temperature in a flow cell system equipped with a gas fed, porous electrode. The effects of current, electrolyte flow, and aprotic media on the extent of degradation of hexachlorobenzene are presented.


Mathematical Modeling Of A Nickel-Cadmium Battery: Effects Of Intercalation And Oxygen Reactions, Deyuan Fan, Ralph E. White Jan 1991

Mathematical Modeling Of A Nickel-Cadmium Battery: Effects Of Intercalation And Oxygen Reactions, Deyuan Fan, Ralph E. White

Faculty Publications

Extensions are presented for a previously published (1) mathematical model of a nickel-cadmium (Ni-Cd) cell. These extensions consist of intercalation thermodynamics for the nickel electrode and oxygen generation and reduction reactions during charge and overcharge. The simulated results indicate that intercalation may be important in the nickel electrode and that including the oxygen reactions provides a means of predicting the efficiency of the cell on charge and discharge.

Analysis Of Bacterial Genome Organization And Replication Using Pulsed-Field Gel Electrophoresis, A. Dingwall, L. Shapiro, Bert Ely Oct 1990

Analysis Of Bacterial Genome Organization And Replication Using Pulsed-Field Gel Electrophoresis, A. Dingwall, L. Shapiro, Bert Ely

Faculty Publications

The techniques described in this chapter provide a framework with which to begin an analysis of important features of bacterial genome organization and gene function. In this report we describe the preparation of chromosomal DNA, conditions for digestion with restriction endonucleases, and electrophoretic methods that result in the optimal resolution of large DNA restriction fragments. The sizes of the separated fragments can be summed to accurately determine genome size. The fragments can also be probed in hybridization experiments to produce low-resolution genomic restriction maps, and the precise locations of insertion or deletion mutations can be rapidly identified. In addition, PFGE …

A New Chloroplast Protein Is Induced By Growth On Low Co2 In Chlamydomonas Reinhardtii, Catherine B. Mason, Livingston J. Manuel, James V. Moroney Jan 1990

A New Chloroplast Protein Is Induced By Growth On Low Co2 In Chlamydomonas Reinhardtii, Catherine B. Mason, Livingston J. Manuel, James V. Moroney

Faculty Publications

The biosynthesis of a 36 kilodalton polypeptide of Chlamydomonas reinhardtii was induced by photoautotrophic growth on low CO2. Fractionation studies using the cell-wall-deficient strain of C. reinhardtii, CC-400, showed that this polypeptide was different from the low CO2-induced periplasmic carbonic anhydrase. In addition, the 36 kilodalton polypeptide was found to be localized in intact chloroplasts isolated from low CO2-adapting cultures. This protein may, in part, account for the different inorganic carbon uptake characteristics observed in chloroplasts isolated from high and low CO2-grown C. reinhardtii cells.


Insulin Responsiveness In Skeletal Muscle Is Determined By Glucose Transporter (Glut4) Protein Level, M. Kern, J. A. Wells, J. M. Stephens, C. W. Elton, J. E. Friedman, E. B. Tapscott, P. H. Pekala, G. L. Dohm Jan 1990

Faculty Publications

Glucose transport in skeletal muscle is mediated by two distinct transporter isoforms, designated muscle/adipose glucose transporter (Glut4) and erythrocyte/HepG2/brain glucose transporter (Glut1), which differ in both abundance and membrane distribution. The present study was designed to investigate whether differences in insulin responsiveness of red and white muscle might be due to differential expression of the glucose transporter isoforms. Glucose transport, as well as Glut1 and Glut4 protein and mRNA levels, were determined in red and white portions of the quadriceps and gastrocnemius muscles of male Sprague-Dawley rats (body wt. approx. 250 g). Maximal glucose transport (in response to 100 nM-insulin) …

The Costs Of Settlement: The Impact Of Scarcity Of Adjudication On Litigating Lawyers, Kevin C. Mcmunigal Jan 1990

The Costs Of Settlement: The Impact Of Scarcity Of Adjudication On Litigating Lawyers, Kevin C. Mcmunigal

Faculty Publications

This Article, by comparison, focuses on the implications of lack of trial experience for litigating lawyers. Does lack of trial experience affect the way lawyers function in litigation? Does it influence their performance as advocates? As negotiators settling cases? Does it affect adherence to existing ethical standards such as those regarding competence and conflict of interest? Can one expect lawyers to understand, respect, and adhere to the values of an ethical and legal system premised, as ours is, upon a process of adjudication lawyers seldom, if ever, experience? Do the answers to these questions yield any insight for guiding reform …


Design Of High Performance Soft X-Ray Windows, Raymond T. Perkins, David D. Allred, Larry V. Knight, James M. Thorne Jan 1990

Design Of High Performance Soft X-Ray Windows, Raymond T. Perkins, David D. Allred, Larry V. Knight, James M. Thorne

Faculty Publications

X-ray windows are used in sources and detectors to separate the neighborhood of the x-ray generation or detection from the use environment. While each use has its own requirements, there are some principles that should be used in designing an optimal x-ray window. Because x-rays are absorbed to some extent by all materials, minimizing absorption is one criterion in preparing windows. Also, for most uses there is a pressure difference across the window so that ensuring pinhole-free structure and sufficient mechanical strength to support the differential is another criterion for window design. Traditionally, absorption is minimized by fabricating the window …

Rheology Of Aqueous Suspensions Of Polystyrene Latex Stabilized By Grafted Poly(Ethylene Oxide), Harry J. Ploehn, J. W. Goodwin Jan 1990

Rheology Of Aqueous Suspensions Of Polystyrene Latex Stabilized By Grafted Poly(Ethylene Oxide), Harry J. Ploehn, J. W. Goodwin

Faculty Publications

A water-soluble carbodiimide has been used to end-graft aminated poly (ethylene oxide)(PEO) chemically onto colloidal polystyrene particles. Two particle sizes (115 and 347 nm diameter) and two PEO molecular weights (112 000 and 615 000 g mol–1) were combined to give suspensions with four different ratios of polymer layer thickness to particle radius. Electrophoresis demonstrated that the PEO was grafted, not just adsorbed. Dynamic light scattering showed that the adsorbed and grafted layers had similar structures and that non-ionic surfactant perturbed the PEO configurations. Steady shear and oscillatory rheometry indicated that long-ranged polymeric forces between particles governed the …

Predicted Secondary Current Distributions For Linear Kinetics In A Modified Three-Dimensional Hull Cell, F. A. Jagush, Ralph E. White, William E. Ryan Jan 1990

Predicted Secondary Current Distributions For Linear Kinetics In A Modified Three-Dimensional Hull Cell, F. A. Jagush, Ralph E. White, William E. Ryan

Faculty Publications

Current density distribution is an important consideration
for those involved in designing electrochemical systems
and electroplating systems in particular. Although it
is important, the common practice in industry is to use
trial and error to determine designs that optimize current
density distributions in electroplating. The purpose of this
paper is to illustrate the use of the finite element method
(FEM) to predict three-dimensional current density distributions.
