Spinitectus Beaveri Sp. N. (Nematoda: Spiruroidea) From The Bonefish, Albula Vulpes (Linnaeus), In Florida, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Spinitectus beaveri sp. n. from the stomach of Albula vulpes is described. In the male, the maximum length is 6 mm, the esophagus is approximately 30% of the body length, the spicule ratio is 1:2.5 to 3.0, and there are 4 pre- and 5 postcloacal papillae. In the female, the maximum length is 7 mm, the esophagus is approximately 27% of the body length, and approximately 38% of the body length is posterior to the vulva. The species most closely resembles S. carolini Holl, 1928, from which it differs by having 10 to 16 rather than 25 to 35 cuticular …

Concentration Of Co, In The Air Above A Sugar Beet Field, K.W. Brown, Norman J. Rosenberg

School of Natural Resources: Faculty Publications

The concentration of CO, in air sampled above a sugar beet crop was measured during July, August, and early September 1966 at Scottsbluff, Nebr. During July the mean daytime concentration decreased from 310 ppm to 283 ppm as the leaf area index increased from 0.8 to 4.0. Only small deviations from the mean daytime Concentration of 283 ppm occurred during the remainder of the season. The mean nocturnal concentration during this period was 320 ppm and was more variable than the daytime concentration. The daily amplitude of concentration averaged 70 ppm and was as great at times as 100 ppm. …

Response Of Nuclear Emulsion To Electron Beams, Robert Katz, E. J. Kobetich

Robert Katz Publications

A recent theory of particle tracks assumes that the probability P for grain development in nuclear emulsion depends on the local dose E of ionization energy deposited by secondary electrons (delta rays) in the neighborhood of the particle track. The response is assumed to be one of exponential survival; that is, if E₀ is the dose for 37% survival, then P = 1 – exp (-E/E₀). By calculation of the dose E(t) deposited at depth t in the emulsion by normally incident, monoenergetic electron beams, and applying the assumed dose-effect relationship, …

Rbe, Let, And Z/ΒΑ, Robert Katz

Robert Katz Publications

A call has been issued by Turner and Hollister in this journal for nomination of a suitable combination of charge and velocity to replace LET. It is the purpose of this communication to point out that no single combination of these variables can fully characterize track effects, as these are affected by the ratio of the range r_m of the delta ray of maximum energy to the radius a₀ of the sensitive volume.

Electrical Conductivity In Nh4Cl And Nd4Cl Single Crystals, Robert Fuller, F.W. Patten

Robert G. Fuller Publications

Electrical conductivity measurements are reported for normal and deuterated ammonium chloride single crystals in the temperature regions which characterize the pure and the impurity-dominated materials. We conclude from the data that conductivity in ammonium chloride is due to the formation of either cation or anion vacancies and a subsequent process controlled by a proton transfer. Our results are found to be consistent with a model proposed by Herrington and Staveley.

Formation Of Particle Tracks, Robert Katz, E. J. Kobetich

Robert Katz Publications

The formation of particle tracks, and such phenomena as the detection of charged particles and the damage produced by charged particles, are intimately related to the spatial distribution of ionization energy deposited by δ-rays. Changes in the spectrum of δ-rays with the velocity of the primary particle imply that linear measures of the interaction of the primary particle with the medium, such as specific energy loss, or primary ionization, are unsatisfactory measures of effects produced in the medium, for they contain no knowledge of the spatial deposition of the lost energy.

American Sculpture, Norman A. Geske

Sheldon Museum of Art: Catalogs and Publications

The occasion for the present exhibition, the dedication of the Sheldon Sculpture Garden, marks the completion of one of the most important gifts ever made to the University of Nebraska and to the people of the state. The importance of the gift lies not only in the fact of the distinguished building and the art objects which it houses, but also in the fact of their presence as a potential, a place and a situation where the creative spirit, traditional and activist, may find a laboratory, a workshop and an audience.

The garden is first of all a physical enlargement …

Influence Of Dietary Supplements Of Cholesterol And Vitamin D On Certain Components Of The Blood And Body Of Growing-Finishing Swine, M. H. Jurgens, E. R. Peo, Jr.

Department of Animal Science: Faculty Publications

The American public has been made extremely conscious of the concept that saturated fat and cholesterol may be involved in atherosclerosis in man. Likewise, because of their content of cholesterol and saturated fatty acids, animal products have become engrossed in a controversy concerning their role in the atherogenic process. No definite conclusions have been made in this area and until further research advances in the field of atherosclerosis, the animal scientist may have to concern himself with modifying the animal product in such a way that it will be more acceptable to the American public. The degree to which this …

Effect Of Feeding-Fasting Interval On Finishing Pigs: Weight Gain, Feed Utilization And Physical And Chemical Carcass Measurements, T. L. Veum, W. G. Pond, L. Dale Van Vleck, E. F. Walker Jr., L. Krook

Department of Animal Science: Faculty Publications

Thirty-two Yorkshire pigs (49 kg body weight, 108 days of age) were used to determine the effect of feeding-fasting interval on rate of body weight gain, feed utilization and carcass and organ measurements at a slaughter weight of approximately 90 kilograms. Treatments were: (1) Continuous ad libitum feeding,(2) ad libitum 1 day, fasted on alternate days, (3) ad libitum 1 day, fasted 2 days, (4) ad libitum 1 day, fasted 3 days. Average daily gain was reduced progressively as severity of the fasting-feeding interval was increased. Efficiency of feed utilization, likewise, was reduced as the severity of feed restriction increased, …

Influence Of Dietary Supplements Of Vitamin D3 And Various Fats On Cholesterol And Fatty Acid Composition Of The Blood And Body Of Growing-Finishing Swine, M. H. Jurgens, E. R. Peo, Jr., P. E. Vipperman, Jr., R. W. Mandingo

Department of Animal Science: Faculty Publications

Previous work at this station suggested that vitamin D₂, when fed with or without dietary cholesterol, depressed blood cholesterol levels of swine (Jurgens, Peo and Vipperman, 1967) and rats (Jurgens, Blunn and Peo, 1968). While not proven to be the cause, blood cholesterol levels have been used as one of the main criteria to estimate the development of atherosclerosis in man (Rabinowitz, Meyerson and Wohl, 1960; Swell, Law and Treadwell, 1962). Several investigators have reported that supplementation of unsaturated fats (Ahrens et al., 1957; Okey and Lyman, 1957; Avigan and Steinberg, 1958; Peifer, 1966) and especially linoleic …

Diammonium Citrate And Diammonium Phosphate As Sources Of Dietary Nitrogen For Growing-Finishing Swine, G. F. Wehrbein, P. E. Vipperman Jr., E. R. Peo, Jr., P. J. Cunningham

Department of Animal Science: Faculty Publications

Many scientists are concerned about the possibility Of a protein shortage in the near future. Since the pig will be placed in direct competition with man for many of the proteins presently used in feeds, it has become increasingly important to determine if other sources of nitrogen can serve as a replacement for some of the non-essential amino acid nitrogen in natural proteins.

Effect Of Feeding-Fasting Interval On Finishing Pigs: Blood Urea And Serum Lipid, Cholesterol And Protein Concentrations, T. L. Veum, W. G. Pond, E. F. Walker Jr., L. Dale Van Vleck

Department of Animal Science: Faculty Publications

A system of restricted feeding in which feed is entirely withheld for intervals of 24, 48 or 72 hr. following a 24-hr. period of ad libitum feeding in continuous sequence throughout the finishing period depresses weight gain and efficiency of feed utilization in direct relation to duration of the fasting period and has marked associated effects on carcass measurements, gland and organ weights and a small effect on fatty acid composition of the back fat (Veum et al., 1970). Cohn (1963) and Leveille and Hanson (1965, 1966) have shown marked changes in metabolism of nutrients and in body composition associated …

Systematic Infections For The Assay Of Plant Viruses, Myron K. Brakke

Department of Plant Pathology: Faculty Publications

The first infectivity assays of plant viruses relied on the percentage of inoculated plants becoming systemically infected. The use of systemic infections for assays became unfashionable, however, after the discovery of local lesions and the demonstration that their numbers depended on virus concentration. Continued emphasis on local lesions over the years led to the widely held belief that systemic infections could not be used for a reliable and accurate assay of plant viruses. There was never any good statistical evidence for this viewpoint. In fact, no thorough investigation has been published of the accuracy of "systemic assays" of plant viruses, …

Effect Of Temperature On Food And Water Intake And Rumen Fermentation, W. R. Gengler, F. A. Martz, H. D. Johnson, G. F. Krause, Leroy Hahn

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

The purpose was to determine volatile fatty acid concentrations at normal (18 C) and high (35 C) ambient temperature, and to determine the effect of increasing the rumen temperature with an intra-ruminal heating coil in an 18 C ambient temperature.

Evaluating Circulation Cleaning By Analysis Of Soil Depletion From Surfaces, R. G. Arnold, R.B. Maxcy

Department of Food Science and Technology: Faculty Publications

The rate of soil removal and its nature were studied with a small commercial high-temperature short-time pasteurizer. The commercial recirculation system was altered to provide a single pass of cleaning solution through the equipment to observe progress of cleaning. A composite of the first 38 liters was taken after 1.5 minutes. Subsequent samples were taken after 3, 6, 22 and 21 to 22 minutes. Cleaning solutions were analyzed by centrifugal fractionation, solvent extraction, gas liquid chromatography, thin layer chromatography and infrared spectroscopy to determine the composition of residue and rate of its depletion.
Results showed both the nature of the …

The Genealogy Of The Outsider's Role In Disclosure Of Equity Ownership In Corporate Acquisition, Melvin Robert Katskee

Nebraska Law Review

The primary issue to be analyzed in this article is the effect which Public Law 90-439, providing for full disclosure of equity ownership of securities under the Securities Act of 1934, will have on the disclosure duty of an outsider making a tender offer for control of a corporation. Resolution of this issue inevitably leads to the battle currently being fought among those learned in the area over the wisdom or lack thereof of placing any disclosure duty upon the outsider.

System Analysis And Nematode Phylogeny, Armand R. Maggenti

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The purpose here is to suggest a method which will permit understanding of the phylogenetic relationships of contemporary representatives of the phylum Nematoda without fossils. It is not my intent to again offer a phylogeny for the Nematoda. To say that no real benefit or knowledge of phylogeny or evolution is possible without fossils is succumbing to apathy. One cannot deny or ignore that all systems, morphological, biological and chemical manifested in modern forms developed by evolutionary sequence. It is true that with a complete fossil record the rates of evolution and developmental pressures could be accurately evaluated. However, in …

Evidence On The Validity Of Management Education, Fred Luthans, James W. Walker, Richard M. Hodgetts

Department of Management: Faculty Publications

The authors feel that more attention should be given to the empirical validation of management education. In order to determine what effect a college degree and the academic major have on promotability, 3,202 marketing personnel of a major petroleum corporation were analyzed.

What effect does a college education have on executive success? Does the major area of study make any difference? Does any kind of management education or development yield tangible returns to an employing organization? In other words, have management formal education and development been empirically validated? Many organizations are seriously beginning to ask these questions. The current body …

Protein Synthesis During Fungal Spore Germination. Iv. Transfer Ribonucleic Acid From Germinated And Ungerminated Spores, James L. Van Etten, R. Kent Koski, Mahmoud El-Olemy

Department of Plant Pathology: Faculty Publications

Transfer ribonucleic acid (tRNA) fractions isolated from germinated and ungerminated spores of Botryodiplodia theobromae and Rhizopus stolonifer had acceptor activity for all 20 amino acids commonly found in protein, when tested with an enzyme fraction from germinated spores. Accordingly, it is unlikely that the absence of tRNA for a particular amino acid limits protein synthesis in fungal spores.

Hatching Of Sod Webworm Eggs In Relation To Low Temperatures, E. A. Heinrichs, Ellis L. Matheny

Department of Entomology: Faculty Publications

Eggs of Chrysoteuchia topiaria (Zeller), Crambus pascuellus floridus (Zeller), and Pediasia trisecta (Walker) were exposed to temperatures of 25, 15, 10, 4, and –10°C. Only those of P. trisecta hatched after exposure to 4°C for 30 days, while none hatched after exposure to –10°C. Eggs of none of the species hatched after exposure to 4 and 10°C for 60 days. Pre-exposure and post-exposure conditioning had no significant effect on percent hatch of P. trisecta eggs, while length of exposure period had a significant effect.
