High-Field Magnetoresistance Of Ordered Beta Brass , David J. Sellmyer, J. Ahn, J.-P. Jan
High-Field Magnetoresistance Of Ordered Beta Brass , David J. Sellmyer, J. Ahn, J.-P. Jan
David Sellmyer Publications
The magnetoresistance of several single-crystal specimens of ordered β-brass has been investigated in fields up to 150 kG. The purity of the samples is sufficiently high (ρ295/ρ4.2≃400) that the high-field condition is satisfied. The results indicate that ordered β-brass is an uncompensated metal and that its Fermi surface is multiply connected. Strong open orbits were observed when the field was in {110} or {100} planes, and this behavior is compatible with the Fermi-surface model predicted by augmented-plane-wave and Green's-function energy-band calculations. Evidence for the existence of higher-order open orbits and two-dimensional regions of open orbits is …
Problems Encountered With Control Networks In Highly-Restructurable Digital Systems, Donald F. Wann, Robert A. Ellis, Mishell J. Stucki, Robert M. Keller
Problems Encountered With Control Networks In Highly-Restructurable Digital Systems, Donald F. Wann, Robert A. Ellis, Mishell J. Stucki, Robert M. Keller
All HMC Faculty Publications and Research
This paper discusses problems encountered with control networks in highly restructurable digital systems. In particular the treatment of implementation errors is covered with emphasis on concurrent processing. The implementation of concurrent processing networks may result in errors which will be quite complex to detect and systematic methods are warranted. Four meta control elements are employed in obtaining convenient concurrent structures. We analyze several error detecting schemes and conclude that the arc-node method with node partitioning appears to be the most realistic approach at this time.
A Noteworthy Record Of The Swift Fox In Mcpherson County, Nebraska, Lawrence J. Blus, Glenn R. Sherman, John Henderson
A Noteworthy Record Of The Swift Fox In Mcpherson County, Nebraska, Lawrence J. Blus, Glenn R. Sherman, John Henderson
Nebraska Game and Parks Commission: Staff Research Publications
An adult female swift fox (Vulpes velox) was killed by an automobile 1 mile E Ringgold, McPherson Co., Nebraska, on 25 March 1966. Standard external measurements (mm) of this specimen are: 723, 275, 132, 59, and weight, 2000 g. This record is approximately 80 miles south of the nearest occurrence listed by Jones (Univ. Kansas Publ., Mus. Nat. Hist., 16: 1-356, 1964) and appears to be the first verification of the occurrence of this fox in the Nebraska Sandhills, although specimens have been taken on all sides of this area. Jones (1964) indicated that this species may have …
Room-Temperature Second-Order Raman Spectra Of Csc1, Csbr, And Csi, A. M. Karo, John R. Hardy
Room-Temperature Second-Order Raman Spectra Of Csc1, Csbr, And Csi, A. M. Karo, John R. Hardy
John R. Hardy Papers
The room-temperature Raman spectra of CsC1, CsBr, and CsI have been computed from a simple, combined density-of-states approximation. Calculations have been made for four different model potential functions and compared with experiment in the cases of CsBr and CsI. In this way it is found that one of the variations, called the DD(-) model, is the most satisfactory. The agreement with the observed spectra is surprisingly close when one considers that no allowance has been made for variations in the elements of the Raman polarizability tensor.

Molecular Orbital Theory Of The Electronic Structure Of Organic Compounds. I. Substituent Effects And Dipole Moments, J. A. Pople, Mark S. Gordon
Molecular Orbital Theory Of The Electronic Structure Of Organic Compounds. I. Substituent Effects And Dipole Moments, J. A. Pople, Mark S. Gordon
Mark S. Gordon
A recent approximate self-consistent molecular orbital theory (complete neglect of differential overlap or CNDO) is used to calculate charge distributions and electronic dipole moments of a series of simple organic molecules. The nuclear coordinates are chosen to correspond to a standard geometrical model. The calculated dipole moments are in reasonable agreement with experimental values in most cases and reproduce many of the observed trends. The associated charge distributions of dipolar molecules show widespread alternation of polarity in both saturated and unsaturated systems. These results suggest that charge alternation may be an intrinsic property of all inductive and mesomeric electronic displacements.

Radiolysis Of The Extract From The Sawdust Of The Ponderosa Pine, Mervin B. York
Loma Linda University Electronic Theses, Dissertations & Projects
Portions of an acetone-hexane (1:4) extract of Ponderosa pine sawdust were exposed to gamma and ultraviolet radiation. The three solutions, including the original, were checked for antibiotic activity on: Staphylococcus aureus Escherichia coli and Bacillus cereus. Results indicated that each solution inhibited the growth of the bacteria.
The three solutions were separated into fractions by 'column' chromatography on silica gel, using chloroform-carbon tetrachloride (1:1) as the elutant and then 10-20-50-80% ethanol in the chloroform- carbon tetrachloride mixture and finally 100% ethanol. Ten fractions were obtained from each sample and these were each tested on the bacteria. Results indicated a number …

Conductive Sphere On A Charged Conductive Plane, Birney Robert Fish
Conductive Sphere On A Charged Conductive Plane, Birney Robert Fish
Masters Theses
Statement of the Problem: If a conductive sphere is placed in contact with a semi-infinite, conductive plane, the configuration constitutes a three-dimensional equipotential surface. Assuming an isolated plane to be electrically charged to a known surface charge density (σ°) originally, it is desired to determine the effect produced by placing a sphere on the plane. Specifically, the purpose of this investigation is to determine the force exerted on the sphere normal to the plane, the total charge acquired by the sphere and the perturbation in the electrical field due to its presence on the plane.

Secondary Reactions And Partial Rate Factors In The Sulfonation Of Chlorobenzene And Toluene, Ernest Arthur Brown
Secondary Reactions And Partial Rate Factors In The Sulfonation Of Chlorobenzene And Toluene, Ernest Arthur Brown
Theses and Dissertations
The sulfonation of chlorobenzene, chlorobenzene-benzene, and toluene-benzene mixtures by sulfur trioxide in liquid sulfur dioxide at -12.5° C. was studied to obtain isomer distribution and relative rate data. The isomer distribution for the reaction on chlorobenzene was determined by an isotope dillution technique. Relative rate experiments were conducted by sulfonating C14 labeled benzene in competition with nonradioactive chlorobenzene and toluene and the count rate of the products was used to determine product composition. Ultraviolet spectrophotometry was also used to investigate variations in isomer distributions as a function of sulfur trioxide concentration. The apparent relative rates of sulfonation (kX/kB) as calculated …

Nurse-Patient Interpretations Of The Nurse's Touch, Judith Ann Trowbridge
Loma Linda University Electronic Theses, Dissertations & Projects
The purpose of this study was to discover whether or not patients and nurses derived a similar meaning from pictures of a nurse touching a patient in various ways. Five by seven inch black and white photographs were shown to thirty patients and thirty registered nurses. The subjects were controlled in regard to sex, race, residence, language, and physical and emotional orientation. They were asked to focus upon the photographed nurse's touch and to tell in one or two words what meaning they felt that the nurse was trying to convey to the patient by her touch. Responses were recorded …

Evaluation Of The Dispersion Relations Of Photoproduction, Paul Finkler
Evaluation Of The Dispersion Relations Of Photoproduction, Paul Finkler
Paul Finkler Papers
A modification of the Omnes method is used to solve the singular integral equations for the 3-3 partialwave amplitudes of photoproduction. The effects of multipion production are assumed to be negligible. The method requires a knowledge of the phase at all energies. Consequently, it is necessary to treat the corresponding pion-nucleon scattering problem to determine the eBect of the high-energy behavior of the phase on the solution for the scattering amplitude at low energies. The sharply resonant nature of the problen suggests an approximation in the form of solution, rather than in the Born terms, which leads to relatively simple …
Anion Contributions To The Electrical Conductivity Of Alkali Chlorides, Robert Fuller, M.H. Reilly
Anion Contributions To The Electrical Conductivity Of Alkali Chlorides, Robert Fuller, M.H. Reilly
Robert G. Fuller Publications
The measured electrical conductivity of pure RbCl is separated into the usual anion and cation contributions with activation energies of 2.55 and 1.58 eV, respectively. By comparison with corresponding results for KC1 and NaCl it is found that the alkali-chloride anion and cation activation energies differ most for nearly equal anion and cation radii. We conclude from this anomalous trend that an extension of conventional theory is required.
