End Of Tour Report Of E. A. Heinrichs, Piant Protection Advisor, Elvis A. Heinrichs

Department of Entomology: Faculty Publications

The opportunity to spend two years in Mysore (March 1970 to April 1972) working with various individuals involved in plant protection has been personally a rewarding and satisfying experience.

In general terms, the purpose of the Plant Protection Advisor was to identify the problems relating to plant protection which limit the spread and production of high yielding varieties and to assist in solving these problems .. The following Operational Work Plan, which was written by my predecessor, was followed and added to in order to achieve the overall objectives: 1. To promote widespread adoption of recommended plant protection practices. 2. …

Population Estimates Of Breeding Birds In North Dakota, Robert E. Stewart, Harold A. Kantrud

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Reasonably accurate measurements of breeding bird populations on large land areas are needed if the overall effects of man's impact on the environment are to be measured and understood. Through use of these data, we will be able to detect the average response of these populations to generalized environmental changes caused by diverse and widespread land-use practices. As this kind of information becomes available, it will serve as the basis for developing appropriate management programs for the purpose of maintaining or increasing breeding bird populations.

Observation Of A Broad Resonance In The 23S Excitation Of Helium By Electron Impact, G. B. Crooks, R. D. Dubois, D. E. Golden, M. Eugene Rudd

M. Eugene Rudd Publications

We have observed a broad P-wave resonance at about 50 eV primary energy in the angular distribution of electrons scattered after excitation of the 2³S state of helium. The resonance has a width of about 15 eV and affects the differential excitation cross section by more than 3 orders of magnitude. It is suggested that this resonance is associated with the temporary formation of triply excited states of the negative helium ion.

Form And Level Of Coumarin In Deer's Tongue, Trilisa Odoratissima, Francis A. Haskins, H. J. Gorz, R. C. Leffel

Department of Agronomy and Horticulture: Faculty Publications

Fresh leaves of deer’s tongue contain large quantities (more than 10% of the dry weight, in some cases) of o-hydroxycinnamic acid (o-HCA). Both cis- and trans-o-HCA are present, and both isomers exist in the fresh tissue predominantly as glucosides. Cured deer’s tongue leaves contain relatively high levels of coumarin and lower amounts of o-HCA glucosides. It is probable that during the curing process cis-o-HCA glucoside is hydrolyzed by an endogenous β-glucosidase, and that the liberated cis-o-HCA lactonizes spontaneously to form coumarin.

The Face Of Malone An Area Of Transition In Lincoln, Nebraska, David A. Montgomery, Frank A. Pratt, Rodney W. Schullig, Boniface N. Madubom, Darshan S. Kang

Geography Program: Faculty Publications

This report concerns Malone, a problem area of Lincoln, Nebraska, that is undergoing considerable change as a result of external influences from the city and the university. In 1971, a graduate Seminar in Urban Geography devoted a semester to the spatial aspects of blight In cities and as a part of this course prepared short reports on specific aspects of Lincoln's example of a blighted zone. The point of departure for the field work was the conceptual framework of the transition zone as it was developed by Burgess in the 1920's and refined by others at a later time, especially …

Detection Of Energetic Heavy Ions, Robert Katz, S. C. Sharma, Mehdi Homayoonfar

Robert Katz Publications

The delta-ray theory of track structure, applied earlier to such 1-or-more hit detection systems as the inactivation of dry enzymes and viruses, the NaI(Tl) scintillation counter, and nuclear emulsion, is extended to the silver activated phosphate glass dosimeter, the LiF thermoluminescent dosimeter, the creation of free radicals in solid biological substances, solid and liquid organic scintillators, and the ferrous sulfate (Fricke) dosimeter. The response of these systems to both gamma-rays and heavy ions is characterized by two parameters: 1) D_γ³⁷, the dose of gamma-rays at which 37% of the sensitive elements remain unaffected by the radiation, and …

Parasites Of Nebraska Pheasants, Ellis C. Greiner

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Parasite prevalence, intensity, and diversity in Nebraska pheasants (Phasianus colchicus) were studied during the fall of 1971. Fifty-four of 63 (86%) pheasants examined for helminths harbored at least one parasite species. Heterakis gallinarum (65% of the pheasants), Choanotaenia infundibulum (48% ). Echinoparyphiuin recurcatum (1 .6% ), and Zygocotyle lunata (1 .6% ) were recovered. Two of 15 (13% birds examined for coccidia possessed Eimeria phasiani. None of 35 pheasants examined for hematozoa had patent infections.

Disappearance And Uptake Of [125I]Fsh In The Rat, Rabbit, Ewe And Cow, D. B. Laster

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

Follicle-stimulating hormone (_NIH-FSH-S8) was labelled with ¹²⁵I to determine its disappearance rate after a single intravenous injection and to determine the level of circulating [¹²⁵I]fsh in the blood after a single intramuscular or subcutaneous injection in the rat, rabbit, ewe and cow. There was a difference in the disappearance and uptake rates among the four species, but the shape of the curve for rate of loss and uptake of labelled fsh was similar in all species. The disappearance of radioactivity occurred at two rates; the first from 1 to 8 min and the second from …

Review Of Check List Of The Helminth Parasites Of African Freshwater Fishes, Glenn L. Hoffman

United States Fish and Wildlife Service: Publications

In spite of the fact that freshwater covers about 74,000 square miles of Africa, surprisingly little work has been done on the helminth parasites of African fishes. This well written and documented book consists of excellent parasite/host and host/ parasite check lists followed by indices of parasites and countries. As the author stated, "It is hoped that this list, combined with the increasing recognition of the importance of fish as a source of protein and, therefore, of the significance of potential pathogens, will provide the necessary stimulus to research workers to rectify these gaps."

Identification Of Experiences In Applied Biological Science And Agribusiness Of Seventh Grade Students, Roy D. Dillon, University Of Nebraska W. Walker

Department of Agricultural Leadership, Education, and Communication: Faculty Publications

In a study to identify the applied biological science-oriented experiences of seventh grade students and to describe student aspirations for future study of applied biological and agribusiness subjects, a random sample of 1,286 7th-grade students was selected in Nebraska. The sample represented l0.l% of the 7th-grade students in Nebraska in 1970, and was selected by drawing a 5% random sample of schools within each of 8 mutually-exclusive class groupings as defined by the Nebraska State Department of Education.

It is clearly evident from the results described that 7th-grade students in Nebraska have gained considerable exploratory experiences through formal and informal …

Considerations Of Professional Responsibility In Probate Matters, William L. Killion

Nebraska Law Review

The legal profession, contrary to the belief of some skeptics, is generally quite concerned with the rigorous observation of ethical standards. All too often, however, the ethical standard becomes hidden in a maze of technical legal problems. Probate, probably more than any other area of practice, abounds in ethical pitfalls. Since such a large portion of probate is thought of as nonadversarial, conflicts of interest often pass unnoticed. Recognizing this recurrence of ethical problems, this comment is both a presentation of some of the more salient problems of professional responsibility arising in probate matters and a critical analysis of the …

Shubnikov-De Haas Effect And Magnetic Breakdown In Be , David J. Sellmyer, I.S. Goldstein, B.L. Averbach

David Sellmyer Publications

Magnetic breakdown in the basal plane of Be was investigated in fields up to 150 kG. Geometrical aspects of the open orbits caused by breakdown are discussed. An estimate of 30 kG for the characteristic breakdown field is obtained by applying the theory of Falicov et al. Shubnikov-de Haas frequency measurements are reported for the central-cigar cross section. These measurements are relevant to a recent conjecture that the Onsager-Lifshitz quantization scheme may be violated in the presence of magnetic breakdown.

Melvin Randolph Gilmore, Incipient Cultural Ecologist: A Biographic Analysis, David L. Erickson

Open Access Master's Theses (through 2010)

This thesis will be a study in microcosm of Melvin R. Gilmore’s Nebraska research. The study analyzes his ethnobiological field work and writings in terms of biographic factors.Gilmore’s ethnobiological research manifests both bioecological and cultural ecological rationales. The thesis shows that Gilmore’s pioneering work in ethnobiology, together with studies by Harrington and others, laid the groundwork for modern cultural ecology as practiced by Julian Steward and others. The author of the thesis used original documents from the Nebraska State Historical Society in his research.

While in Nebraska Gilmore developed an interest in ethnobiology. His initial ethnobotanical field work was related …

Effect Of Fertilization And Management On The Production Of Bromegrass In Northeast Nebraska, G. W. Rehm, W. J. Moline, E. J. Schwartz, R. S. Moomaw

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Several experiments were conducted in northeast Nebraska to determine the effect of fertility and management practices on the production of smooth bromegrass (Bromus inermis Leyss). The effectiveness of the various fertilizer treatments was measured in units of dry matter produced per acre as well as beef produced per acre. Results of these studies showed that the production of bromegrass pastures in Nebraska could be markedly improved through proper fertilization.

Even-Parity Lattice Resonances And Anharmonicity In Ki: Ag+, Roger D. Kirby

Roger Kirby Publications

We report here the observation of four impurity-induced lattice resonances in KI:Ag+. In addition to the well-known T1u symmetry resonant mode at 17.3 cm-1, we have observed two even-parity resonant modes of A1g and Eg symmetries at 25 and 16.35 cm-1, respectively, and a T1u symmetry gap mode at 86.2 cm-1. The two even-parity modes were detected using far-infrared spectroscopic techniques with the sample in an external electric field. The field induces a strong mixing of the modes of opposite parity and results in large field-induced shifts. The Eg symmetry resonance has also been seen in the Raman spectrum of …

Penstemon In Your Garden, R. D. Uhlinger, G. Viehmeyer

Nebraska Agricultural Experiment Station: Historical Circulars

A new race of hardy perennials is beginning to appear in American gardens. These are the penstemons, a genus of plants closely related to the familiar snapdragon, which may become important ornamentals as they be come better known to gardeners. The purpose of this bulletin is to show the possibility of the genus as an ornamental and to suggest species and species hybrids of possible value to Great Plains gardeners; to provide information about propagation and culture; and to encourage gardeners to engage in penstemon breeding as an avocation.

Survival Of Some Freshwater Fishes In The Alkaline Eutrophic Waters Of Nebraska, D. B. Mccarraher

Nebraska Game and Parks Commission: Staff Research Publications

Of 14 species of freshwater fishes held in cages in one or more of 13 alkaline lakes and ponds in Nebraska, few species survived more than a month where carbonate alkalinity, mostly as compounds of Na₂C0₃ and KC0₃, was above 300 mg/liter. Of the 14 species tested, Sacramento perch (Archoplites interruptus), fathead minnow (Pimephales promelas), northern pike (Esox lucius), and the black bullhead (lctalurus melas), were the most tolerant of alkaline environments. Most centrachid fishes except A. interruptusand the green sunfish (Lepomis cyanel!us), did …

Telescopic Observation Of The Moon As A Means For Observing Migration Of The Army Cutworm, Chorizagrotis Auxiliaris (Lepidoptera: Noctuidae), K. P. Pruess, Neva C. Pruess

Department of Entomology: Faculty Publications

Nocturnal insect activity was observed through telescopes focused on the moon. Flight direction was computed and methods were developed for estimating height and determining vertical distribution. Total density was correlated with light-trap catches; effective range of a light-trap was about 7 meters. Species identification was impossible but the method was selective for larger and higher-flying insects. Characteristics of insect activity observed during periods of army cutworm abundance indicate that it orients to the west during spring migration. Activity and altitude of flight were modified by wind direction and velocity, but flight direction during migration was independent of wind.
