Characterization Of Biological Types Of Cattle Iii. Carcass Composition, Quality And Palatability, R. M. Koch, M. E. Dikeman, D. M. Allen, M. May, J. D. Crouse, D. R. Campion

Department of Animal Science: Faculty Publications

Composition and quality characteristics of 1,121 steer carcasses obtained after mating Hereford and Angus cows to Hereford, Angus, Jersey, South Devon, Limousin, Charolais and Simmental sires were compared at a (1) constant age, (2) constant weight, and (3) constant percentage of fat in the longissimus muscle. Taste panel evaluation was made on a subsample of 496 carcasses. Growth rate of retail product, fat trim and bone differed significantly among sire breed groups. Breed group differences in relative proportions of retail product, fat trim and bone were largest when compared at a constant carcass weight and smallest when compared at equal …

Two Possible Source Areas For The Quartzite Artifacts Of The Hudson-Meng Site -- A Comparative Study, Frank Witzel, John Hartley

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Quartzites from quarries at Flint Hill, South Dakota and Spanish Diggings, Wyoming were examined using a binocular and petrographic microscope. A textural difference was discovered between material from the two quarries. Artifacts and debitage from the Hudson-Meng site (25 S x 115) was then examined and compared with quarry material. Tentative quarry affinities have been assigned to a portion of the Hudson-Meng collection.

A Redescription Of Crassicutis Archosargi, A Digenean Exhibiting An Unusual Tegumental Attachment, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The homalometrine Crassicutis archosargi from the northern Gulf of Mexico is redescribed, and some related digeneans are discussed. Numerous unidentified refractile bodies occurred in the tegument and other tissues of a few specimens of C. archosargi, and an intimate relationship between the parasite and its piscine host resulting from a modified tegument is reported for others. Binding by the described adhesive tegument increases the number of known ways digeneans attach to their hosts. Several specimens also harbored a histozoic myxosporidan in several tissues and a flagellate, Hexamita sp., in their ceca.

Electron Transmission Studies Of The Negative Ion States Of Substituted Benzenes In The Gas Phase, Kenneth D. Jordan, J.A. Michejda, Paul Burrow

Paul Burrow Publications

Temporary negative ions of benzene, aniline, phenol, anisole, fluoro-, chloro-, and bromobenzene, formed in the gas phase by capture of electrons into the low-lying π* orbitals, are studied by means of electron transmission spectroscopy. The electron affinities are determined and their relative values are interpreted in terms of resonance and inductive effects.

Fabespora Vermicola Sp. N., The First Myxosporidan From A Platyhelminth, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The myxosporidan Fabespora vermicola sp. n., tentatively placed in the family Myxidiidae, is described from the digenean Crassicutis archosargi in an estuarine fish. The myxosporidan becomes the first known from a platyhelminth and the third from an invertebrate. It differs from the only other member of the genus primarily by having polar filaments 32 to 44 μm long rather than about 8 μm, and an infection with it can stop reproduction in the digenean host either by physical means or by necrosis of gametes.

Interactions Between Insects And Chemical Components Of Sweetclover, G. R. Manglitz, Herman J. Gorz, Francis A. Haskins, W. R. Akeson, G. L. Beland

Department of Agronomy and Horticulture: Faculty Publications

This review concerns the relationship between chemical components found in sweetclover [Melilotus officinalis (L.) Pall. and M. alba Desr.] tissues and insects feeding on these tissues. Coumarin and its related compounds did not appear to influence the feeding of sweetclover aphids [Therioaphis riehmi [Börner)], pea aphids [Acyrthosiphum pisum (Harris)] or potato leafhoppers [Empoasca fabae (Harris)] , however, these materials appeared attractive to sweetclover weevils (Sitona cylindricollis Fåhraeus) and to adult sweetclover root borers [Walshia miscecolorella (Chambers)]. Conversely the feeding of four species of blister beetles (Epicauta sp.] was inhibited by cis-o-hydroxycinnamic acid …

Dairy Cattle Breeding: Contributions Of Research On Field Data, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Papers about dairy cattle breeding published in the Journal of Dairy Science from 1960 through 1975 were categorized according to whether the data came from institutional herds or from field collection and also according to whether the research was done with support of a regional project. Most project papers involved institutional data. The vast majority of non-project papers made use of field data. Nearly all papers classified as theoretical were also associated with field data or field recommendations. The major impact of breeding research projects with field data has been from improved genetic evaluation for production and from development of …

Electronic And Magnetic Properties Of Amorphous And Crystalline Zr40Cu60-XFeX Alloys, F.R. Szofran, G.R. Gruzalski, John W. Weymouth, David J. Sellmyer, B.C. Giessen

David Sellmyer Publications

Electronic states and localized magnetic moments and their interactions were studied in amorphous and crystalline Zr₄₀Cu_60-xFe_x alloys for 0≤x≤12. Electrical resistivity, magnetic susceptibility, and high-field magnetization measurements were performed. In the dilute crystalline alloys Curie-Weiss behavior is seen in the susceptibility and is associated with localized moments (μ_eff≈3μ_B) on the iron atoms. At higher iron concentrations ferromagnetism is observed. Curie-Weiss behavior also is seen in the susceptibility of the dilute (0eff≈0.7μ_B). There is some evidence that the local environment of the Fe atoms is important and may depend …

Economic Impact Of Railroad Branch-Line Abandonments: Results Of A Southcentral Nebraska Case Study, Dale G. Anderson, Floyd D. Gaibler, Mary Berglund

Department of Agricultural Economics: Faculty Publications

Some 249 miles of Nebraska rail line have been abandoned since 1963; another 310 miles are in contention at abandonment proceedings. The abandonment of these and other lines could have serious economic implications for grain elevators, farmers, and rural communities.

Track abandonment is occurring during a time of rapid expansion in the grain industry. U. S. corn and grain sorghum production increased more than 40 percent during the decade ending in 1973. Exports of these commodities increased 157 percent during the same period. Increases in grain production and exports, along with a shorter harvest season, are placing great strains on …

Mosses Of The Great Plains: Introduction And Catalogue, Steven P. Churchill

School of Biological Sciences: Faculty Publications

This account initiates a series of articles concerning the mosses of the Great Plains. The boundary of this region (Fig. 1) is adopted in part from a parallel study currently in progress on vascular plants (McGregor et aI., 1977). However, in addition, this moss study includes that region of Canada studied by Bird (1962). The total area included in this study of the Great Plains thus occupies about 665 thousand square miles, extending from southern Manitoba to southeastern Alberta, south to northeastern New Mexico and northwestern Oklahoma.

Crum, Steere and Anderson (1973) have listed 1,170 species, 267 genera, and 58 …

Properties Of Soils In The Solid Set Irrigation Area Of The Sandhills Agricultural Laboratory, David T. Lewis

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The introduction of irrigated agriculture and the attendant increase in intensity of land use for agricultural purposes in the Sandhills region of Nebraska requires additional data regarding soils in the area. This work investigated landscape relationships and some of the morphological, physical, chemical, and mineralogical properties of the soil in one irrigated valley. The soils in this valley contain greater amounts of silt and clay than do the soils on the nearby dunes. In addition, some of the valley soils contain layers of much higher clay content and corresponding cation exchange and water holding capacity than the dunal soils and …

Botanical Pioneers Of The Nebraska Sandhills, Curtis Twedt, Carl Wolfe

Nebraska Game and Parks Commission: Staff Research Publications

The Nebraska Sandhills comprise an area of about 20,000 square miles, extending from about 980 30' to 1030 . Northern and southern boundaries are parallel with the Niobrara and Platte River valleys, respectively. The Sandhills merge with the Loess Hills physiographic region at the southeast, resulting in irregular interfaces of low dunes with clay bluffs and canyons of the latter region (Elder, 1969).

Supralinearity Of Thermoluminescent Dosimeters, Leif Larsson, Robert Katz

Robert Katz Publications

The supralinear response of thermoluminescent dosimeters (TLDs) after irradiation with gamma- or beta-rays can be decomposed by use of the cumulative Poisson distribution into a sum of 1-or-more and 2-or-more hit components, suggesting the coexistence of both types of trap structures. Following the response of other 1-hit detectors, and of biological cells to energetic heavy ions, we expect and find that the supralinear response tends to disappear with alpha particle, and with neutron irradiation, and that the supralinear, or 2-hit, component tends to be more responsive to high LET (Linear Energy Transfer) radiations. Since the response of biological cells to …

The Quantum Defect Theory Approach, Anthony F. Starace

Anthony F. Starace Publications

The Quantum Defect Theory (QDT) is a method of using the analytically known properties of excited electrons moving in a pure Coulomb field to describe atomic photoabsorption and electron-ion scattering processes in terms of a few parameters. These parameters may be determined either from experimental data or from ab initio theoretical calculations. In addition, they are usually nearly independent of energy in the threshold energy region (i.e., within a few eV of the atomic ionization threshold). Thus the determination of these parameters at any single energy suffices to predict the variation with energy of numerous atomic properties in the threshold …

An Evaluation Of Transactional Analysis As A Strategy Of Organization Development, Gilbert Frank Nykodym Ii

Department of Communication Studies: Dissertations, Theses, and Student Research

Introduction

Organizational Development (OD) and Transactional Analysis embrace a humanistic philosophy of organizational life. Connor noted: "Commitment to traditional humanistic concerns of individual growth, development, dignity, worth, and meaning is expressed in all OD literature (1975, p. 349)." Transactional Analysis (TA) takes an identical position.

We are living in the Age of Aquarius. Knowledge is no longer coveted by the chosen few who call themselves experts. Anyone who can read can gain expertise. It is fitting and appropriate at this time in human history that a model for behavior and human interaction (TA) has come along that can be used …

Flight Of The Sea Ducks, Paul A. Johnsgard

Papers in Ornithology

Their migration routes have been charted. Their breeding biology is known. Their eggs meat and feathers have long been used by man. But eiders at sea remain an enigma.

Nesting in colonies that can number hundreds of birds, the eiders are among the most conspicuous of tundra-breeding birds. Although female eiders are a study in grays and browns that match the arctic tundra, the males are most boldly patterned in black and white, with striking green head colors. When the nesting season ends, the birds disperse over the vastnesses of the northern oceans, out of range of most human observers. …

An Evaluation Of Treatment Recommendations For The Greenbug, Schizaphis Graminum, On Susceptible Grain Sorghum In The Clay County, Nebraska Pest Management Project, Bruce John Monke

Open Access Master's Theses (through 2010)

All fields involved in this study were located in Clay County, Nebraska and were farmed by cooperators in the Pest Management Project. Many of the field procedures were adapted from those used by the University of Nebraska Agronomy Department Outstate Testing Service. The purpose of this study was to examine, under Nebraska conditions, the accuracy of the currently accepted guidelines for determining the necessity of greenbug control on grain sorghum.

The data in this study do not support specific guidelines based only on greenbug populations or plant damage sustained due to greenbug feeding, for controlling greenbugs on susceptible grain sorghum. …

Performance Of Certified Seed Lots Of Dawson Alfalfa, W. R. Kehr, G. R. Manglitz

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Breeder, foundation, and certified seed lots of Dawson alfalfa, Medicago sativa L., were tested to determine stability in performance during three generations of seed increase under certification. Two field experiments were conducted, a seeded forage yield test and a space-planted test. Greenhouse experiments included separate tests for resistance to pea aphids, spotted alfalfa aphids, and bacterial wilt. Results obtained on certified Dawson alfalfa seed classes in field and greenhouse experiments were in agreement with the original variety description.

Bacteria In The Air Of Housed Swine Units, L.F. Elliot, T.M. Mccalla, J.A. Deshazer

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Two housed, swine-growing-finishing units were studied for numbers of total bacteria, fecal coliforms, Staphylococcus, and Salmonella in the air. At 30.5 and 122 cm from the floor, total colony-forming particles, as tested, averaged 3.4 x 10) and 1.3 x 105/m³ of air, respectively; whereas fecal coliform counts averaged 24 x 103 and 1.9 x 103/m³ of air, respectively. Only 41% of the organisms growing on Staphylococcus 110 medium tested as Staphylococcus. Of 458 Staphylococcus isolates, 5 were coagulase-positive. No Salmonella were detected in the air of the units tested.

Liberalized Agricultural Trade -- At The Multilateral Trade Negotiations, Bilaterally Or Not At All!, Clayton K. Yeutter

Clayton K. Yeutter, United States Secretary of Agriculture: Papers

For most of the 20th century, much of the world has fretted about agricultural surpluses. This has been particularly true of the major producing nations, with the United States being in the forefront. Only a decade ago, our "ever normal granaries" were bursting at their steel seams, and we were immersed in another agonizing appraisal of U.S. farm policy.

Then the shock came! In 1972 everything went wrong on the production front droughts, early frosts, monsoon problems, even the fish meal supply diminished because of an uncooperative ocean current. We suddenly realized that man was not quite as omniscient as …
