On The Normalized Yield (Events/Rad/Dalton) Of Biological Molecules Irradiated With Energetic Heavy Ions, Robert Katz

Robert Katz Publications

When irradiated with electrons or γ-rays, a number of biological molecules display an approximately linear relationship between the reciprocal of the D₃₇ dose and molecular weight. This is conventionally plotted as a relation between target molecular weight and true molecular weight, where the target molecular weight M_t is given as: M_t × (D₃₇) = α (1) where α is approximately 10¹⁰ Da-rad/eV of the energy assumed to be “deposited in the target” in a single “hit” for expression of the end-point. We emphasize that D₃₇ is expressed in rads for we will later …

Radial Distribution Of Dose, Robert Katz, Matesh N. Varma

Robert Katz Publications

The radial distribution of dose about the path of a heavy ion, principally from delta rays, is one of the central contributions of atomic physics to the systematization of high LET radiation effects in condensed matter, whether the detection arises in chemical, physical, or biological systems. In addition to the radial distribution of dose, we require knowledge of the response of the system to X-rays or gamma-rays or to beams of energetic electrons such that the electron slowing-down spectra from these radiations can approximate the slowing-down spectra from delta rays even at different radial distances from the ion's path. A …

Additional Fossil Evidence On The Differentiation Of The Earliest Euprimates, Kenneth D. Rose, Thomas M. Bown

United States Geological Survey: Staff Publications

Several well-preserved jaws of the rare North American omomyid primate Steinius vespertinus, including the first known antemolar dentitions, have been discovered in 1989 and 1990 in the early Eocene Willwood Formation of the Bighorn Basin, Wyoming. They indicate that its dental formula is as primitive as those in early Eocene Donrussellia (Adapidae) and Teilhardina (Omomyidae) - widely considered to be the most primitive known euprimates - and that in various dental characters Steinius is as primitive or more so than Teilhardina. Therefore, despite its occurrence at least 2 million years later than Teilhardina, S. vespertinus is the …

Dietary And Parasitological Analysis Of Coprolites Recovered From Mummy 5, Ventana Cave, Arizona, Karl Reinhard, Richard H. Hevly

Karl Reinhard Publications

Four coprolites were excavated with Burial 5 at Ventana Cave. a partially mummified five-year-old child. Two coprolites were granular and dark in color and two were fibrous and light in color. The coprolites are remains of the child's intestinal contents and were submitted for dietary and parasitological analysis. No parasites were found. The fibrous coprolites proved to be remains of highly masticated mesquite pods (Prosopis). The granular coprolites consist of seeds of saguaro cactus (Carnegiea gigantea). Pollen analysis reveals two dietary pollen types, both derived from cactus. No evidence of cultivated plants except for a trace amount of …

The Transformation Of Professionals Into Self-Managing And Partially Self-Designing Contributors: Toward A Theory Of Leadership-Making, George B. Graen, Mary Uhl-Bien

Department of Management: Faculty Publications

Self-managing teams are rapidly approaching the popularity of Quality Circles in both the popular and organizational literature. However, before this promising notion becomes the next panacea for the ills of our declining international competitiveness, we must investigate the fundamental question of how superior managed professionals become transformed into self-managers. This paper presents a model of a leadership-making process which purports to produce the transformation of superior manager professionals into self-managing and partially self-designing units. The focus of this paper is on the upper end of the self- managing category of Hackman’s (1986) authority matrix. A life cycle model of leadership-making …

Design For Testability And Test Generation With Two Clocks, Vishwani D. Agrawal, Sharad C. Seth, Jitender S. Deogun

School of Computing: Conference and Workshop Papers

We propose a novel design for testability method that enhances the controllability of storage elements by use of additional clock lines Our scheme is applicable to synchronous circuits but is otherwise transparent to the designer. The associated area and speed penalties are minimal compared to scan based methods, however, a sequential ATPG system is necessary for test generation. The basic idea Is to use independent clock lines to control disjoint groups of flip-flops. No cyclic path are permitted among the flip-flops of the same group. During testing, a selected group can be made to hold its state by disabling its …

School Psychology At The University Of Utah, William R. Jenson, Elaine Clark, Susan M. Sheridan, Howard N. Sloane, Thomas J. Kehle

Department of Educational Psychology: Faculty Publications

The article describes the history of the school psychology program at the University of Utah from 1978, and discusses responsibilities of a school psychologist: utilizing and disseminating the knowledge base of psychology in educational problem solving; operating from a scientist-practitioner model, wherein practices prescribed are based on research-validated procedures and a sound theoretical framework. School psychologists are generalists and specialists and function as researchers, diagnosticians, interventionists, assessors, consultants, and advocates for children. Professionally, school psychologists are identified with the overarching goals of enhancing the academic, social, and emotional well-being of students.

Three-Dimensional Triple-Resonance Nmr Of 13C/15N-Enriched Proteins Using Constant-Time Evolution, Robert Powers, Angela M. Gronenborn, G. Marius Clore, Ad Bax

Robert Powers Publications

Recently it has been convincingly demonstrated that 30 triple-resonance NMR provides a practical alternative for obtaining sequential resonance assignments in larger proteins ( 1, 2). This approach requires a set of five or six 30 NMR experiments that correlate the various protein backbone nuclei. Details regarding the mechanisms and technical implementations of these experiments have been described previously ( 3- 5). Two of the experiments used in this approach correlate backbone Hα and Cα resonances with either the intraresidue carbonyl resonance (CO) or the ¹⁵N resonance of the succeeding residue and are referred to as HCACO and HCA(CO)N, respectively. …

‘Starlight’ —Great Northern Dry Bean, D.P. Coyne, James R. Steadman, Dale T. Lindgren, D.S. Nuland

Department of Agronomy and Horticulture: Faculty Publications

The release of ‘Starlight’, a Great Northern dry bean cultivar (Phaseolus vulgaris L.), fulfills a need in western Nebraska for a cultivar with a relatively large seed size and a uniformly bright-white seedcoat (Korban et al., 1981). Foreign buyers of Great Northern beans desire a larger seed than the current predominant Great Northern cultivar Beryl (J.A. McGill, Jr., personal communication). In addition, the cultivar possesses improved architectural avoidance mechanisms to white mold disease (WMD) incited by Sclerotinia sclerotiorum (Lib.) de Bary (Coyne, 1980), a serious problem in some seasons in western Nebraska.

Monofilament Lines Fail To Protect Grapes From Bird Damage, Don Steinegger, Danilo A. Agüero, Ron J. Johnson, Kent M. Eskridge

Department of Agronomy and Horticulture: Faculty Publications

Birds feeding on horticultural crops may cause extensive losses, but control techniques currently available are not always practical or otherwise appropriate. Control of certain birds is attempted by placing widely spaced lines or wires over or around sites needing protection (Pochop et al., 1990). Recently, Knight (1988) reported observations that monofilament lines could be used to protect various horticultural crops, including grapes, from bird damage. However, more closely controlled research was needed to better quantify effectiveness of this technique for various bird species. The objectives of this study were to determine the effectiveness of monofilament lines in protecting ripening grapes …

Plasmodium Falciparum Appears To Have Arisen As A Result Of Lateral Transfer Between Avian And Human Hosts, A. P. Waters, D. G. Higgins, T. F. Mccutchan

Harold W. Manter Laboratory of Parasitology: Library Materials

It has been proposed that the acquisition of Plasmodium falciparum by man is a relatively recent event and that the sustained presence of this disease in man is unlikely to have been possible prior to the establishment of agriculture. To establish phylogenetic relationships among the Plasmodum species and to unravel the mystery of the orign of P. fakiparum, we have analyzed and compared phylogenetically the small-subunit ribosomal RNA gene sequences of the species of malaria that infect humans as well as a number of those sequences from species that infect animals. Although this comparison confirmed the three established …

Modeling AiXGa1-XAs Optical Constants As Functions Of Composition, Paul G. Snyder, John A. Woollam, Samuel A. Alterovitz, Blaine D. Johs

Department of Electrical and Computer Engineering: Faculty Publications

Three models for the dielectric function ε_x (hv) of Ag_xGa1_1-xAs are reviewed. All are based on measured optical constants at discrete compositions. The validity of each mode1 near critical pint energies, and otherwise, is evaluated. Only the energy-shift model is appropriate over the entire available spectrum ( 1.5-6.0 eV), including the band-gap (E₀) region.

Evaluating The States Of Mind Model: Comparison To An Alternative Model And Effects Of Method Of Cognitive Assessment, Richard G. Heimberg, Monroe A. Bruch, Debra A. Hope, Mark Dombeck

Department of Psychology: Faculty Publications

Two studies were conducted evaluating aspects of the States of Mind (SOM) Model proposed by Schwartz (1986; Schwartz & Garamoni, 1986, 1989) with a sample of social phobic subjects. First, the SOM ratio [positive thoughts/(positive + negative thoughts)] based on a thought-listing task was compared to a ratio based on Kendall and Hollon’s (1981) “power-of-nonnegative-thinking” model [negative thoughts/(positive + negative + neutral thoughts)], and the relationship of each ratio to criterion measures was assessed. The two ratios were highly correlated and related to several criterion measures, raising questions about the role of neutral thoughts in the internal dialogue. Second, SOM …

Current And Future Job Responsibilities Of The Secondary Agriculture Education Instructor As Perceived By Teachers, Superintendents, And Principals In Nebraska, Noel Erskine

Department of Agricultural Leadership, Education, and Communication: Dissertations, Theses, and Student Research

The study was conducted to evaluate the differences in how Nebraska agricultural educators and their administrators viewed the current and future importance of selected job responsibilities of the secondary agriculture education instructor in Nebraska. A mailed survey was used to collect data for the survey. The questionnaire was mailed to a random sample of 40 instructors, principals and superintendents of high schools in Nebraska that offer agricultural education. An overall return rate of 69 percent was achieved. Respondents were asked to rate the current and future importance of 58 selected job responsibilities of the agricultural education instructor. A 1 to …

A Report On Black-Tailed Prairie Dogs In Nebraska, Their Biology, Behavior, Ecology, Management, And Responses To A Visual Barrier Fence, Nancy S. Foster

School of Natural Resources: Dissertations, Theses, and Student Research

I examined the effects of a visual barrier fence, which had a see-through visibility of 600/0, on the foraging, vigilance, and aggressive behaviors of adult female black-tailed prairie dogs from June through August 1990 in central Nebraska. I also examined changes in their home ranges and use of an area in response to this fence. Prairie dogs prefer an open view of their surroundings. Therefore, I expected animals near a visual barrier to spend more time in vigilance and aggression, and less time foraging. Adult female prairie dogs exposed to the visual barrier devoted more time to foraging and less …

Kinetic-Energy Density Functional For A Special Shape-Invariant Potential Of A One-Dimensional Two-Level System , Jiushu Shao, John J. Stezowski

John J. Stezowski Publications

By introducing the concept of supersymmetry to quantum mechanics, several authors have shown that exactly soluble potentials, including all those well known, are easily constructed. Is the kinetic-energy density functional corresponding to these potentials a simple form? We show that the answer is no, even to the simplest one, the harmonic potential, if one builds the kinetic-energy density functional from the reduced density matrix.

Predictions Of Cell Damage Rates For Lifesat Missions, Francis A. Cucinotta, William Atwell, Alva C. Hardy, Michael J. Golightly, John W. Wilson, Lawrence W. Townsend, Judy Shinn, John E. Nealy, Robert Katz

Robert Katz Publications

Radiological experiments with cell cultures are expected to be performed on Lifesat to study possible gravitational dependence on cellular response. Predictions of cell damage rates for well-studied systems are expected to help guide in the selection of orbits and the design of experiments. In this report we estimate the fractions of cell death and neoplastic transformation of C3H10T1/2 cells (cultured mouse cells) for the proposed Lifesat orbits. The parametric cellular track model of Katz et al. (refs. 1 and 2) is employed using cellular response parameters derived from the experiments of Yang et al. (refs. 3 and 4). The contributions …

Media Stereotyping: A Comparison Of The Way Elderly Women And Men Are Portrayed On Prime-Time Television, Joetta A. Vernon, J. Allen Williams Jr., Terri Phillips, Janet Wilson

Department of Sociology: Faculty Publications

This content analysis of 139 programs and 2,211 characters updates and extends previous research on the way elderly people, and especially elderly women, are presented on prime-time television. Findings indicate that females and the elderly continue to be significantly underrepresented. Comparisons of elderly men and women showed patterns of traditional stereotypes, with men more likely to be depicted positively on 7 of 9 desirable traits and women more likely to be depicted negatively on 6 of the 7 undesirable traits which showed a gender difference. However, the proportional differences for specific characteristics typically were neither large nor statistically significant, suggesting …
