Food Preference As A Factor In Distribution And Abundance Of Phoetaliotes Nebrascensis, K. P. Pruess

Department of Entomology: Faculty Publications

Western wheat grass, Agropyron smithii, was the plant most frequently ingested by Phoetaliotes nebrascensis (Thomas) in 4 of 5 habitats and was preferred in all. All grasses were eaten to some extent; nonpreferred plants may support populations in otherwise suitable habitats. Most forbs were unattractive but all tested species of Cichoriaceae were acceptable. Plant-finding was by random searching; selection was made only after contact through the mouthparts. While habitats in which preferred hosts were more abundant had higher grasshopper populations, annual changes in grasshopper abundance within a habitat were independent of abundance of primary food plants.

Penicillium Urticae Bainier Enumeration In Soils, Fred A. Norstadt, T. M. Mccalla

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

Studies of stubble-mulched soils from three locations in Nebraska showed larger total counts (bacteria and actinomycetes) and fungi than in plowed soils. Penicilliurn urticae Bainier numbers increased in subtilled soil compared with either plowed soil or subtilled soil with crop residues removed.** P. urticae B. produces patulin, a phytotoxic substance. This organism is regarded as one of the possible sources of the toxicity problem arising in stubble mulching. Penicillium expansum Link and patulin were studied in the apple replant problem.

The purpose of this paper is to present methods to estimate P. urticae B. numbers in soils and demonstrate patulin …

Absence Of Dominance Of The Cu Gene In Influencing O-Hydroxycinnamic Acid Content In Melilotus Alba, Francis A. Haskins, H. J. Gorz

Department of Agronomy and Horticulture: Faculty Publications

The average content of o-hydroxycinnamic acid in sweetclover plants of the Cucu genotype was 36% of the level found in CuCu plants. Thus, the level of o-hydroxycinnamic acid in the F₂ was more like the content of the cucu parent than that of the Cucu parent, indicating that cu was partially dominant over Cu. The calculated value for the degree of dominance of cu over Cu was +0.299. The partial dominance of the cu gene provides an explanation for the difficulty experienced in classifying plants in segregating populations.

Relationship Between Type Traits And Longevity Of Daughters Of Hew York Holstein Sires, L. Dale Van Vleck, D. B. Filkins, H. W. Carter, C. L. Hart

Department of Animal Science: Faculty Publications

The percentage of 40 or more daughters having four lactations of 81 New York Holstein artificially insemination sires was correlated with the percentage of daughters in 66 type categories measured in the first lactation and their average first-lactation milk yield. Multiple regression on these type and production traits accounted for 92% of the variation in percentage of daughters having four lactations. A subset of 33 traits accounted for 82% of the variation. Traits with the largest standard partial regressions for longevity were milk production (.41), udder edema (.87 and .71), deep body (.53), medium upstandingness (.41), fore udder attachment (--.86 …

Sweetclover-Weevil Feeding Deterrent B: Isolation And Identification, W. R. Akeson, H.J. Gorz, Francis A. Haskins

Department of Agronomy and Horticulture: Faculty Publications

Deterrent B, a compound apparently involved in the resistance of Melilotus infesta to the sweetclover weevil Sitona cylindricollis, has been isolated from leaves by a combination of preparative paper chromatography, sublimation, and crystallization. The compound has been identified as ammonium nitrate. Isolated deterrent B and ammonium nitrate have identical feeding deterrent activities. Although the deterrent principle was isolated as the ammonium salt, nitrate ion is probably responsible for the deterrent activity in vivo.

Pulsational Instabilities In Hydrogen-Poor Massive Blue Stars, Norman R. Simon

Norman R. Simon Papers

The structure and pulsational properties of massive stars with helium cores and thin, hydrogen-poor envelopes have been investigated. The core structures are very insensitive to modifications of the hydrogen envelope. However, it is found that the total stellar radius and luminosity are modified by the integrated hydrogen content and by the hydrogen gradient, respectively. The models are pulsationally stable under modest conditions of central condensation (due to a hydrogen-burning shell and/or high hydrogen content). The unstable models are energized almost entirely by the helium reactions in the core, while most of the damping occurs in the thin hydrogen envelope. For …

A Descriptive Analysis Of Nebraska's Unicameral Legislature, Harry W. Wade

Nebraskiana Publications: Resources and Materials on the 37th State

What is the Nebraska "Unicameral" experience in handling problems relating to organization, procedure, leadership, and lobbying? Has the Nebraska system attracted different kinds of people to legislative service? This study was undertaken for the purpose of determining, on the basis of an investigation of the only one-house state legislative system in the nation, how Nebraska unicameralism functions in present-day circumstances and if the Nebraska experience has produced evidence of alternative ways of dealing with contemporary legislative problems which would tend to bear out the expectations of the supporters of the single-house legislature. Because the Nebraska unicameral plan employs an important …

Some Parameters Of The Second-Order Conditioning Of Fear In Rats, Alan Kamil

Papers in Behavior in Biological Sciences

The effects of CS1 duration, partial reinforcement, and trace conditioning on second-order conditioned suppression were investigated, employing 64 rats as Ss. In Experiment 1, the clearest second-order conditioning was obtained when CS1 duration was the same during both the first- and the second-order conditioning phases of the experiment. In Experiment 2, somewhat better second-order conditioning was obtained when first-order conditioning had been under conditions of partial reinforcement, delay CS-US pairing. In neither experiment were CS1 suppression and CS2 suppression during second-order testing well correlated. This aspect of the results raised the question of the influence of nonclassical conditioning factors on …

The Identification Of Cis-Ii, I2-Methylene-2-Hydroxyoctadecanoic Acid From Thiobacillus Thiooxidans, H. W. Knoche, J. M. Shively

Department of Biochemistry: Faculty Publications

A polar fatty acid has been observed as a component of an

ornithine-containing lipid of Thiobacillus thiooxidans. A

comparison of thin layer chromatographic mobilities of reference

compounds to those of the natural acid and its derivatives

suggested that the acid was a 2-hydroxy fatty acid.

The presence of a cyclopropane function in the acid was

indicated by l4e-Iabeling experiments and infrared spectroscopy.

Mass spectrometry of the methyl ester and the acetylated

methyl ester of the natural acid provided a molecular

weight for the acid. Equivalent chain lengths were determined

for the natural acid, the acid obtained by oxidative

decarboxylation of …

Levels Of Calcium And Phosphorus For Growing-Finishing Swine, G. W. Libal, E. R. Peo, Jr., R. P. Andrews, P. E. Vipperman, Jr.

Department of Animal Science: Faculty Publications

The calcium and phosphorus requirements of growing-finishing swine have not been satisfactorily resolved. Recently it was suggested that levels of calcium and phosphorus needed in diets of growing-finishing (G-F) swine for optimum growth and feed conversion may be different from those needed for optimum bone development (Miller et al., 1960; Lloyd et al., 1961; Rutledge et al., 1961; Combs et al., 1966). The problem of determining calcium and phosphorus requirements is further magnified by the observation of Chapman et al. (1955) that G-F swine do not utilize plant phosphorus as efficiently as inorganic phosphorus. In …

Business In Nebraska #296, May 1969, Dorothy Switzer, E. S. Wallace, Warren Viessman Jr., R. L. Busboom

Business in Nebraska

Employment in Export-Related Jobs in Nebraska (Dorothy Switzer)

How many Nebraskans are employed in export-related jobs? What percentage of the state's total private employment is auributable to export business ?

These questions are raised frequently, but until recently no answers could be based on more up- to - date data than 1960 figures. Estimates of employment related to exports of goods, by state, based on data from a 1965 survey of the origins of exports, have now been provided, however, by the Bureau of Labor Statistics of the U.S. Department of Labor. Although unfortunately these estimates do not reflect the …

The Lewis And Clark Trail

United States National Park Service: Publications

The idea of a Lewis and Clark Trail was conceived in May 1961 by the late J. N. "Ding" Darling, cartoonist-conservationist for the Des Moines Iowa, Register. Following his death, friends and associates created the J. N. "Ding" Darling Foundation to advance his ideas on resource conservation.

Effects Of Dietary Levels Of Manganese And Magnesium On Performance Of Growing-Finishing Swine Raised In Confinement And On Pasture, A. J. Svajgr, E. R. Peo, Jr., P. E. Vipperman, Jr.

Department of Animal Science: Faculty Publications

Research on the optimum dietary levels of manganese and magnesium for growing swine is limited. Johnson (1940) fed pigs diets containing 0.3 to 100 ppm Mn and observed no difference in growth rate. Similarly, Liebholz, Speer and Hays (1962) found that 0.4 ppm Mn in the diet of baby pigs was sufficient to support maximum growth. A level of 4,000 ppm Mn was not toxic but growth rate of the pigs was reduced.

Growth Of Yorkshire Suckling Pigs, W. F. Gipp, W. G. Pond, L. Dale Van Vleck, P. D. Miller

Department of Animal Science: Faculty Publications

The birth weights and daily liveweights for 87 male and 99 female pigs reared under drylot conditions were obtained over a 3-week period and used to construct a growth curve for the very young male and female pig. Analysis of variance was used to test litter and sex main effects and the litter x sex interaction effect on liveweight. The daily standard deviations of the 186 pig sample were calculated and are presented in graphic form. No significant difference between the growth of male and female pigs of this young age were found. The average birth and first-, second- and …

Sire Evaluation For Economic Merit, J. W. Wilton, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Procedures for selecting sires are compared in terms of making maximum genetic progress in economic merit. A quadratic index, a simplified form of the quadratic index and a linear index to evaluate economic merit, and a restricted index to improve milk as much as possible while holding milk fat percentage constant, all result in nearly equal expected genetic progress in economic merit. Selection for milk production results in less expected genetic progress in economic merit, the extent of the decrease depending on the economic value of milk production at a given base test and on the test differential.

Predicted Versus Measured Production Differences Using Summer Air Conditioning For Lactating Dairy Cows, Leroy Hahn

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

Predicted summer production losses were made for Holstein cows in three widely separated locations in the United States where field investigations of air conditioning for dairy barns have been completed. These losses, based on a functional relationship developed from Missouri Climatic Laboratory data and local climatological data, were compared to the measured losses at each location. Correlation of losses for Holstein cows varied from excellent in northern Ohio to good in southern Louisiana and central Missouri. Variations due to hotter- or cooler-than-normal summer seasons and level of production were reasonable at all locations.

Life Insurance Prices, Joseph M. Belth

Nebraska Law Review

Life insurance textbooks refer only briefly to the subject of price competition, and even some of these references contain statements that are inconsistent in certain respects. On the one hand, in discussions of regulation, the statement is sometimes made that life insurance rates generally are not regulated and that competition is felt to be a sufficient protection against excessive rates. On the other hand, in discussions of differences among insurance carriers, the statement is sometimes made that price comparisons in life insurance are sufficiently complex to be well beyond comprehension for the layman. Taken together, such statements raise an important …

The Nebraska Judicial Article: A Time For Reform, Thomas D. Sutherland

Nebraska Law Review

The purpose of this Comment is to examine further a proposal for complete court reform in Nebraska put forth in an article entitled The Justice of the Peace in Nebraska, and to study some of the advantages of a unified court system. Such a court system would vest the judicial power of the state in one court of justice, rather than in several autonomous courts. However, this one court would be divided into courts of different levels under one administrative head. The problem is approached in two ways, which will first indicate the need for some kind of reform, …

Equilibrium Concentration Of Impurity-Vacancy Complexes, Robert Fuller, H.B. Rosenstock

Robert G. Fuller Publications

In recent years the transport properties of alkali halide crystals have been discussed in terms of fi ve defects, i.e. isolated anion vacancies, isolated cation vacancies, isolated impurity ions, nearest neighbor vacancies of opposite electric charge (divacancies), and nearest neighbor impurity- vacancy complexes [1]. Originally these defects were treated as noninteracting particles located at appropriate lattice sites (the presence of divacancies and complexes was not assumed) and the defect concentrations were obtained from statistical mechanics. Subsequently the defects were allowed to interact with oppositely charged defects located at nearest neighbor lattice sites and the concentrations of divacancies and complexes were …

Axenic Ovarial Explants From The Marine Nematode Deontostoma Californicum On Culture Media, D. R. Viglierchio, Armand R. Maggenti, R. N. Johnson

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The gonads of Deontostoma californicum were isolated from the organismal environment by dissection. In an attempt to approximate the in vivo condition and to maintain in vitro architecture and function ten media recommended for the culture of insect cells or organs were tested. The media were prepared in two series: one according to published recommendations and the second substituting filtered seawater for the inorganic salts and distilled water. Media were prepared as both liquid and gel (agar) with and without antibiotics. Whole animals and eggs were placed on the same culture media series as the ovarial explants. Ovarial explant reaction …

Managerial Analysis Of Doctoral Candidates And Professors: Research Attitudes And Interpersonal Relations, Fred Luthans, Richard M. Hodgetts

Department of Management: Faculty Publications

The authors feel that managerial analysis can contribute to the better understanding of many problems facing the modern university. This study, in analyzing the staffing problems of colleges of business administration, utilizes the research attitudes and interpersonal relations between doctoral candidates and their professors. The body of management knowledge is usually associated with business organizations. However, many other types of organizations in modern society have utilized management knowledge to solve their problems. Government organizations, hospitals, and the military draw from and add to the general body of management knowledge.
