On The Mechanism Of Low-Temperature Termolecular Atomic Recombination, Russell T. Pack, Richard L. Snow, Wesley D. Smith Jan 1972

On The Mechanism Of Low-Temperature Termolecular Atomic Recombination, Russell T. Pack, Richard L. Snow, Wesley D. Smith

Faculty Publications

A simple theory of gas-phase termolecular atomic recombination kinetics is presented which treats the bound-complex (BC) mechanism in a fashion which parallels the Roberts, Bernstein, and Curtiss resonance theory of the energy-transfer (ET) mechanism. The ET rate constant has a low temperature maximum, but the BC rate constant does not. The contributions of the two mechanisms to the low-temperature recombination of hydrogen atoms, with He, Ar, and H2 as third bodies, are estimated and compared. The presence (absence) of a low-temperature maximum in the observable total rate constant is determined by absence (presence) of bound vibrational levels of the hydrogen-third …

A Study Of Cross-Cultural Groups At Malcolm Price Laboratory School; University Of Northern Iowa, Leander A. Brown, Richard F. Strub, Shirlee Rainey Jan 1972

A Study Of Cross-Cultural Groups At Malcolm Price Laboratory School; University Of Northern Iowa, Leander A. Brown, Richard F. Strub, Shirlee Rainey

Faculty Publications

A brief history of the integration efforts of the school and the resulting interracial conflict is presented. From this background evolved the cross-cultural groups which are the focus of this paper. Essentially; discussion was used for exploring the issues which were identified as impediments to good relationships within the school; (1) too few black faculty and students; (2) the impact of "Tomism;" (3) geographic location of students' homes; (4) differing interests of black and white students; (5) the need for extra-school interracial contact; and (6) inhibitions; both social and parental; against interracial contact; especially dating. The results of a questionnaire; …


An Assessment Of The Differences Between High And Low Achieving Students. Final Report, Ralph Scott, Jon A. Ford Jan 1972

An Assessment Of The Differences Between High And Low Achieving Students. Final Report, Ralph Scott, Jon A. Ford

Faculty Publications

Primarily a longitudinal and quantitative analysis of achievement functioning; this experiment sought to identify factors which promote or impair the learning of individual children. The 683 Junior High students were divided into one of eight groups according to sex; race and whether their seventh grade Iowa Test of Basic Skills Composite score was above or below that expected from their Kindergarten Metropolitan Readiness Test performance. The incidence of males and females making unexpected gains (Ups) or losses (Downs) was approximately the same; but a significantly greater proportion of black children made greater than expected achievement gains. Thirty-three Up Ss were …

High-Pressure Equation Of State For Nacl, Kcl, And Cscl, Daniel L. Decker Jul 1971

High-Pressure Equation Of State For Nacl, Kcl, And Cscl, Daniel L. Decker

Faculty Publications

A calculation of the equation of state for NaCl from a Mie-Grüneisen equation was repeated using more accurate values of the zero-pressure compressibility. It was also extended to KCl and CsCl. An analysis of this approach to pressure calibration indicates that it will yield pressures with about the same accuracy as can be presently achieved by experimental measurements above 25 kbar, and thus furnishes a temporary practical pressure scale.

Lamb-Mössbauer Factor Of Sodium Ferrocyanide, Daniel L. Decker, L. E. Lortz Feb 1971

Lamb-Mössbauer Factor Of Sodium Ferrocyanide, Daniel L. Decker, L. E. Lortz

Faculty Publications

Using a set of commercially prepared sodium ferrocyanide absorbers enriched to 91.2% Fe57 the Lamb-Mössbauer factor was measured to be 0.28±0.03. The thickness of Fe57 for these absorbers was measured using x-ray absorption techniques and was found to be considerably smaller than that advertised by the manufacturer even after correcting for the size of the ferrocyanide particles in the absorbers.

A Variable Coeficient Of Restitution Experiment On A Linear Air Track, R. Gruebel, James C. Dennis, L. Choate

Faculty Publications

A system consisting of two pendula attached to an air cart is mathematically analyzed, and the coefficient of restitution is shown to pass through a deep minimum. The solution to the small angle equation of motion is transcendental and provides an exercise in graphical methods for the beginning mechanics student.


Theories Of Water Pollution Litigation, Peter N. Davis Jan 1971

Theories Of Water Pollution Litigation, Peter N. Davis

Faculty Publications

The common law has traditionally provided the rules that govern relationships among landowners in their use of watercourses. These rules are embodied in the eastern United States in the doctrine of riparian rights, which addresses itself both to water quantity, and to water quality. Persons complaining of pollution of waters abutting their lands have, in addition to redress by complaint to the state pollution control agency, redress by lawsuit against the alleged polluter. This common law supplements the body of statutory law regulating the waters of the state for the benefit of the people.

High-Pressure Phase Studies On Sodium–Potassium Alloys, D. Ray Anderson, J. Bevan Ott, Rex J. Goates, H. Tracy Hall Jan 1971

High-Pressure Phase Studies On Sodium–Potassium Alloys, D. Ray Anderson, J. Bevan Ott, Rex J. Goates, H. Tracy Hall

Faculty Publications

The solid–liquid phase diagrams were investigated to 60 kbar for elemental sodium, potassium, and various sodium–potassium alloys. The data for Na and K are in general agreement with those of earlier workers. In the alloy system the temperatures of both the peritectic and eutectic halts increase as the pressure increases, but with different slopes, so that the two invariant points merge at approximately 35 kbar. Above this pressure, two halts are again observed. One increases with increasing pressure, and the other decreases with increasing pressure up to 55 kbar, where it abruptly starts increasing again. Melting points for samples in …


Two-, Three-, And Four-Particle Spatial Correlations Among Tertiary Cosmic Ray Muons, David D. Busath, R O. Stevenson Jan 1971

Two-, Three-, And Four-Particle Spatial Correlations Among Tertiary Cosmic Ray Muons, David D. Busath, R O. Stevenson

Faculty Publications

Showers of muons which result from interactions of primary cosmic rays high in the atmosphere appear deep underground as bundles of nearly parallel muons. For threshold energies of 1 TeV and arrival zenith angles of 45 degrees, those events having a small mean number of muons are described by a power law distribution in shower size having an exponent of ≅ -3.7 and a radial density distribution that decreases with distance R from the shower axis a little less rapidly than exp(-R/5.4 m). Comparison of new data on four muon spatial correlations in terms of the same phenomenology with data …

Rayleigh Hysteresis Shape: Its Relationship To Displacement Distance Of A Single Domain Wall In 50% Ni–Fe, R. C. Woodbury, M. R. Hunt Mar 1970

Rayleigh Hysteresis Shape: Its Relationship To Displacement Distance Of A Single Domain Wall In 50% Ni–Fe, R. C. Woodbury, M. R. Hunt

Faculty Publications

The need to measure the displacement distance of domain walls from equilibrium for very weak alternating fields (H ≪ coercive force) in bulk magnetic material has prompted a study of the possible use of the opening of the Rayleigh hysteresis loop to indicate the amount of wall displacement. This paper contains (1) a review of the theoretical relationship between hysteresis shape and the displacement distance of a domain wall, based upon defect-energy models of Rodbell and Bean, and Baldwin; and (2) an experimental approach which provides a measure of the wall displacements versus hysteresis shape for 50% Ni–Fe tape. Discrepancies …


Proposed Thermodynamic Pressure Scale For An Absolute High-Pressure Calibration, Daniel L. Decker, J. Dean Barnett Feb 1970

Proposed Thermodynamic Pressure Scale For An Absolute High-Pressure Calibration, Daniel L. Decker, J. Dean Barnett

Faculty Publications

The field of high pressure has developed rapidly over the past few years to a point where relatively sophisticated experiments are being attempted. In many experiments it is no longer sufficient to qualitatively estimate the pressure or to base conclusions on experimental results tied to an empirical pressure parameter. One desires to accurately know the pressure dependence of physical quantities related to a true thermodynamic scale.
