Patterns Of Cell Division, Dna Base Compositions, And Fine Structures Of Some Radiation-Resistant Vegetative Bacteria Found In Food, S. W. Sanders, R. Burt Maxcy

Department of Food Science and Technology: Faculty Publications

Representative highly radiation-resistant Moraxella-Acinetobacter (M-A), Pseudomonas radiora, Micrococcus radiodurans, and Micrococcus radiophilus exhibited a wide variety of division systems and cell wall characteristics. However, the most resistant M-A possessed unusually thick cell walls, indicating a possible role of the cell wall in radiation resistance in the M-A. Thick septation was present in most of the bacteria studied, but was absent in P. radiora, thus excluding this as a necessity for high resistance. Reliable determination of the number of division planes of the M-A for use as a taxonomic criterion was achieved by the direct observation of dividing cells. …

"External Fact As An Editorial Problem", G. Thomas Tanselle

Documentary Editing: Journal of the Association for Documentary Editing (1979–2011)

In 1978 a provocative article by Dr. Tanselle. "The Editing of Historical Documents;' appeared in the annual volume of Studies in Bibliography, edited by Fredson Bowers. In the 1979 edition of Studies, Dr. Tanselle has followed his earlier survey with a probe of specific problems. The Bibliographical Society of the University of Virginia has permitted the newsletter to reproduce several paragraphs from Tanselle's latest contribution.

Check Readers Cheaply, Ronald T. Farrar, Will Norton Jr.

College of Journalism and Mass Communications: Faculty Publications

Newspaper readership is in decline throughout the country. Circulation, though increasing, is not increasing as rapidly as new households are being created. People who do buy newspapers seem to spend less and less time reading them. There is, in short, profoundly serious competition for the reader's time and the advertiser's dollar, and a number of newspapers--notably afternoon newspapers in major markets--have been, or are being, overwhelmed.

One by-product of this struggle for readership has been the development by many publishers of a deep and respectful major metropolitan daily newspaper now employs a research director--or an expensive outside research consulting firm, …

Bacteriocin-Like Substances Produced By Rhizobium Japonicum And Other Slow-Growing Rhizobia, D. C. Gross, A. K. Vidaver

Department of Plant Pathology: Faculty Publications

Bacteriocin-like substances were commonly produced by slow-growing Rhizobium japonicum and cowpea rhizobia on an L-arabinose medium. Antagonism between strains of R. japonicum was not detected in vitro; however, such strains were often sensitive to some bacteriocins produced by cowpea rhizobia. Inhibitory zones (2 to 8 mm from colony margins), produced by 58 of 66 R. japonicum test strains, were reproducibly detected with Corynebacterium nebraskense as an indicator. Quantitative production was not related to symbiotic properties of effective strains, since nine noninfective strains and one ineffective strain produced bacteriocin. Eight R. japonicum strains that did not produce bacteriocin nevertheless formed effective …

The Status Of Student Press Freedom In Nebraska’S High Schools, Robin W. Hadfield

Open Access Master's Theses (through 2010)

Have student rights to a free press advanced during the period since certain free expression rights of high school students were established by the U.S. Supreme Court in 1969? Are students censored in what they print in their high school newspapers? And if they are, who is doing the censoring – principals, advisers or the student themselves? In an attempt to examine these questions, the author undertook a study of student press rights in Nebraska’s high schools. Previous cases and literature on the topic were studied and a survey was taken of Nebraska high school principals and high school press …

Chapter 7: The Inexpensive Unification Of Clio And Piaget, L. C. Duly

ADAPT Program: Essays

The ADAPT History course at the University of Nebraska-Lincoln is still very much in its infancy. To date it has consisted of a two-semester course dealing with the nature of “revolution and other forms of change" in Modern Europe from 1776 to the present. The thematic tone of its title has been kept deliberately vague; its content has tended to stress the origin, development, and change of ideas, institutions, and value-structures within the established chronology, all of which one would likely find in the traditional “Western Civilization” course. The course has not attempted to present the study of man in …

Radiobiological Aspects Of Supralinear Photographic Emulsions, Robert Katz, Edward C. Pennington

Robert Katz Publications

Abstract Nuclear emulsions of the Ilford K series, exposed to X-rays from 15 to 150 kV_p and systematically underdeveloped, exhibit supralinear blackness-exposure curves ranging from 1- to 4-hit in character, and whose shape is the same at all excitation voltages. Processing can be so adjusted that the curve shape is well represented by the model, and matches an experimental dose-response curve obtained with hamster cells after irradiation with gamma rays. The effective grain size of these emulsions is 1.3 μm when normalized to unit density material for comparison with the radiation-sensitive elements of biological cells. With fractionated exposures, response …

Micro-Relief Surface Depression Storage: Changes During Rainfall Events And Their Application To Rainfall-Runoff Models, J. Kent Mitchell, Benjamin A. Jones Jr.

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Micro-relief surface depression storage is one of the dynamic components of the rainfall-runoff process. The quantification of the effect of rainfall intensity and duration on the micro-relief was the subject of this study. Micro-relief measurements were made on 88 soil bin samples before and after the application of simulated rainfall events. The surface depression changes are described with empirical equations, using basic rainfall, surface hydrology, and soil parameters and their cross products as independent variables. A rainfall-runoff model demonstrates the value of a dynamic description of the surface depression storage function.

Development Of Thermal Infrared Imagery To The Detection Of Urban Heat Islands, Ronald L. Block

Open Access Master's Theses (through 2010)

The primary objective of this study is to demonstrate the scientific validity of using airborne and satellite thermal infrared sensing as a technique for detecting the urban heat islands of selected towns and cities in eastern Nebraska. Emphasis is on the development of the technique, rather than on specific applications of its methodology.Two objectives of application include ascertaining the relationship between: 1) large structural density index values and high density renditions; and 2) increasing city size and increased density ranges.Several instruments and techniques were used to determine the feasibility of thermal infrared sensing. Density renditions were obtained by use of …

Double Mode Pulsation As A Resonance Phenomenon, Norman R. Simon

Norman R. Simon Papers

It is proposed that the maintenance of stable double-mode pulsation involves a resonant interaction between the two excited modes. This hypothesis yields a simple explanation of the narrow range of period ratio (P₁/P₀) observed in both the double-mode Cepheids and the double-mode AI Velorum stars. The resonance idea is consistent with the under-massive models previously invoked to match the double-mode Cepheids, but seems to rule out normal Population I masses for the AI Velorum stars. It is argued that observational evidence regarding the pulsations of the AI Vel objects does not at present preclude …

Calculated Yields And Slowing-Down Spectra For Electrons In Liquid Water: Implications For Electron And Photon Rbe, R. N. Hamm, H. A. Wright, Robert Katz, J. E. Turner, R. H. Ritchie

Robert Katz Publications

Detailed Monte Carlo calculations have been carried out of slowing-down spectra and yields for a number of end-points for electrons in liquid water. These investigations were made to study differences in physical effects of different low-LET radiations and implications for RBE. Initial electron energies from 1 keV to 1 MeV were used, and all secondary electrons were followed in the computations until their energies fell below 10 eV. Though there are substantial differences in the slowing-down spectra at energies near and above the K-shell ionization potential of oxygen, the energy spectrum of electrons at lower energies is found to be …
