Religio-Scientific Relationships In The Twentieth And The Thirteenth Centuries, Nicholas Dietz Jr.
Religio-Scientific Relationships In The Twentieth And The Thirteenth Centuries, Nicholas Dietz Jr.
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
Our whole planet became conscious of a religio-scientific relationship during the moon-orbiting Apollo 8 flight, at Christmas, 1968. Its astronauts were the first men to leave the gravitation of Earth, the first to come under another gravitational body, the first to travel so far from Earth (233,000 miles), the first to see the other side of the moon. Contemplation of the scientific and technical achievements of their Mission against a new background of the incredibly immense Universe and the wonders of its creation, led them to depart from flight plan to re-read to planet Earth from outer space the Genesis …
Seriation Of Certain Arikara Villages, J.J. Hoffman
Seriation Of Certain Arikara Villages, J.J. Hoffman
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
Selected villages of 18th century Arikara Indians are seriated on the basis of presumably sensitive pottery traits. Two agreeing temporal models, one statistical and one graphical, are derived from the manipulated data. The statistical model is further abstracted to present a relative temporal placement of the individual villages. The models and their interpretations differ somewhat from previous work on the subject. Certain ideas regarding modification of the techniques employed are discussed. A few thoughts are also injected regarding the use of temporal models, seriation, and statistics in general for the interpretation of past behavior.

On November 29, 1971, the Hamilton County Ground Water Con·servation District sponsored a meeting on groundwater management and regulation. The meeting was held at Aurora, Nebraska, and was designed for irrigators from groundwater conservation districts and county irrigation associations. Various men from state and federal agencies spoke about a variety of problems that a.re related to groundwater management. Two of the talks that were presented at the meeting are reproduced here, as is a discussion of the rules and regulations that relate to the use of groundwater in the state of Nebraska.

Power Requirements Of Indoor Model Aircraft Having Tandem Lifting Surfaces, Walter Erbach
Power Requirements Of Indoor Model Aircraft Having Tandem Lifting Surfaces, Walter Erbach
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
The indoor model is a free-flying rubber-powered model aircraft designed to achieve maximum flight duration through light construction and proper aerodynamic configuration. So fragile it can be flown only indoors, a world competition model weighs approximately one gram, is powered by a motor of equivalent weight, and under ideal conditions in sufficiently large halls is capable of single-flight durations exceeding forty-five minutes. World competition regulations established by the Federation Aeronautique Internationale restrict only wing span, thus design problems arise from a different direction from those of man-carrying aircraft. With the wing planform largely determined by the given span, the designer …
Multi-Interval Sturm-Liouville Transform And Its Applications, Pau-Chang Lu
Multi-Interval Sturm-Liouville Transform And Its Applications, Pau-Chang Lu
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
The method of finite integral transforms (Eringen, 1954; Churchill, 1955; Sneddon, 1955; Cinelli, 1965; Roettinger, 1947) has gradually replaced the classical method of separation of variables. This is undoubtedly due to its compact and almost drill-like formalism. Wherever applicable, it has also replaced the Laplace transform with the resulting avoidance of cumbersome contour integrals in the inversion.
In this paper, we are concerned with solving, by such a transformational or operational method, the following general boundary-value problem:
Li (fi) + M (fi) = gi (x), Ci-l

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.

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) Dγ37, the dose of gamma-rays at which 37% of the sensitive elements remain unaffected by the radiation, and …
Late Quaternary Eustatic Sea-Level Changes Along The Malibu Coast, Los Angeles County, California, Peter W. Birkeland
Late Quaternary Eustatic Sea-Level Changes Along The Malibu Coast, Los Angeles County, California, Peter W. Birkeland
United States Geological Survey: Staff Publications
Late Quaternary relative sea-level changes along the Malibu coast can be deciphered by study of geomorphic features and marine and associated stream deposits. Evidence for such changes includes (a) stream downcutting in large valleys during low stands of sea level, (b) stream aggradation in the same valleys during high stands of sea level, and (c) marine shoreline angles whose altitudes coincide with the tops of valley-fill stream deposits. This evidence, and open-system uranium-series dates for shells from the Corral and Dume terrace deposits, provide a time scale for certain sea-level changes. Evidence from other …

Miocene Amphicyonids (Mammalia, Carnivora) From The Agate Spring Quarries, Sioux County, Nebraska, Robert M. Hunt Jr.
Miocene Amphicyonids (Mammalia, Carnivora) From The Agate Spring Quarries, Sioux County, Nebraska, Robert M. Hunt Jr.
Department of Earth and Atmospheric Sciences: Faculty Publications
The Miocene late Arikareean land mammal "age" is largely defined by the faunal assemblage from the Agate Spring Quarries and other nearby localities in the Harrison Formation of Sioux County, Nebraska. Amphicyonid carnivores of the genera Cynelos Jourdan and Ysengrinia Ginsburg were previously known only from European Oligocene and Miocene deposits. These genera are now known from the Harrison Formation of Sioux and Box Butte counties, western Nebraska, and therefore the late Arikareean fauna now includes three amphicyonids: Cynelos sp., (?) Ysengrinia sp., Daphoenodon superbus Peterson. The stage of evolution of these carnivores suggests a correlation of the Agate Spring …

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.

Even-Parity Lattice Resonances And Anharmonicity In Ki: Ag+, Roger D. Kirby
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 …
Survival Of Some Freshwater Fishes In The Alkaline Eutrophic Waters Of Nebraska, D. B. Mccarraher
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
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.
Cellular Inactivation By Heavy Ions, Neutrons, And Pions, Robert Katz, S. C. Sharma, M. Hamayoonfar
Cellular Inactivation By Heavy Ions, Neutrons, And Pions, Robert Katz, S. C. Sharma, M. Hamayoonfar
Robert Katz Publications
The delta-ray theory of the inactivation of cells by energetic heavy ions describes cellular survival after heavy ion bombardment through a two-component survival model, in which 4 operational parameters (E0,m0, σ0, and κ) describe the response of a particular cellular variety in a particular ambient condition, for an arbitrary radiation environment. The quantities m and E0 are the extrapolation number and extrapolated D-37 dose of the survival curve after gamma-ray irradiation. The quantities σ0 and κ are found from the initial slope of survival curves after irradiation with ions of different LET, …
