Geochemistry Of The Cenozoic Volcanic Rocks Of Ross Island And Vicinity, Antarctica, S. S. Goldich, S. B. Treves, N. H. Suhr, J. S. Stuckless

Department of Earth and Atmospheric Sciences: Faculty Publications

The Cenozoic volcanic rocks of Ross Island and vicinity, Antarctica, are surface flows, tuffs, breccias, and small intrusives. The prominent rock is basanitoid. Alkali-basalt magma reached the surface over an appreciable length of time and was differentiated to produce a rock series: basanitoid → trachybasalt → phonolite. The alkalic, silica-undersaturated rocks are part of a larger petrologic province composed of volcanic centers in a belt nearly 2,000 km long roughly parallel to the Transantarctic Mountains. Two trends of magmatic differentiation are apparent. At depth the fractional crystallization of olivine, clinopyroxene, and opaque oxide minerals, all of which are abundant as …

Bionomics Of Insects Associated With Corn In The Nebraska Sandhills, J. L. Wedberg, J. B. Campbell, T. J. Helms

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Investigations were conducted in the Nebraska Sandhills to determine the impact of transition from grassland to irrigated corn on selected insect species, to identify indigenous species that may be economically important to corn production, and to provide a point of reference for future development of pest management programs for irrigated corn.

Sodium Bentonite In Ruminant Rations, Daniel P. Colling

Open Access Master's Theses (through 2010)

Sodium bentonite, an expanding clay, is being used in many different ways in industry today.The livestock and feed industry, for example, use it in many different ways.It is used as a pellet binder to maintain a fat test in dairy animals, as a digestive aid in the poultry industry and as a “buffering agent” in feedlot rations.

A two-pronged investigation was undertaken to determine the effect sodium bentonite could have on the ruminant feeding industry.One part of the investigation sought to determine if bentonite could partially or entirely alleviate subclinical lactic acidosis with problem rations.The other part of the investigation …

Collecting Nebraska's Colorful Agates, Roger K. Pagian

Conservation and Survey Division: Faculty and Staff Publications

The inexperienced gemstone collector may sometimes think of Nebraska as being a place Mother Natural forgot. Mother Nature, however, may be enjoying a little chuckle at the many gem collectors who drive right through Nebraska on their way to more exotic gem fields.

Critical Flicker Frequency In A Harp Seal: Evidence For Duplex Retinal Organization, Charles D. Bernholz, Michael L. Matthews

University of Nebraska-Lincoln Libraries: Faculty Publications

Critical flicker frequency (CFF) was investigated in a free swimming harp seal using behavioral techniques. The resulting CFF vs intensity curve indicates a definite rod/cone break, suggesting a duplex photoreceptor population, whose presence had not been observed in previous morphological reports.

Path Integrals With Arbitrary Generators And The Eigenfunction Problem, William B. Campbell, Paul Finkler, C. E. Jones, M. N. Misheloff

Paul Finkler Papers

We generalize the path integral formalism of quantum mechanics to include the use of arbitrary infinitesimal generators, thus providing explicit expressions for solutions of a wide class of differential equations. In particular, we develop a method of calculating the eigenfunctions of a large class of operators.

Pollution Abatement From Cattle Feedlots In Northeastern Colorado And Nebraska, L. K. Porter, F. G. Viets Jr., T. M. Mccalla, L. F. Elliott, F. A. Norstadt, H. R. Duke, N. P. Swanson, L. N. Mielke, G. L. Hutchinson., A. R. Mosier, G. E. Schuman, Lynn R. Shuyler, C. E. Evans

United States Environmental Protection Agency: Publications

Climatic factors, feedlot runoff, and organic material in the runoff were evaluated in experimental and commercial feedlots. The effects of slope, stocking rates, terraces, basins, and holding ponds were evaluated to obtain the best controls for containing runoff. In eastern Nebraska, 70 cm annual precipitation produces 23 cm of runoff; whereas, in northeastern Colorado, 37 cm annual precipitation gives only 5.5 cm of runoff. Large applications of runoff liquid, up to 91 cmon grass-Ladino and 76 cm on corn, in Nebraska did not decrease yields; however, in northeastern Colorado, the concentrated high-salt runoff required dilution before direct application to crops. …

Vegetation Development In Relation To Age Of River Stabilization Structures Along A Channelized Segment Of The Missouri River, John Arthur Vaubel

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

During the summer of 1974, I sampled sites of vegetation representative of successional trends in plant communities along the Missouri River floodplain from Sioux City, Iowa, to Rulo, Nebraska. Five district community types listed from youngest to oldest are as follows: Salix spp. – dominated, Populus deltoides – dominated, Platanus occidentalis-Ulmus rubra – dominated, Tilia americana-Quercus rubra – dominated, and Quercus macrocarpa-Carya ovata – dominated vegetation.

The technique of relating vegetation succession to age of river stabilization structures was found to be useful and offered a quite precise method of developing a timescale …

Phyllodistomum scrippsi sp. n. is described from the urinary bladder and Neobenedenia girellae is reported from the skin of Pimelometopon pulchrum from La Jolla, California. Phyllodistomum scrippsi differs from P. borisbychowskyi in possessing lobed vitell ari a, fewer extracecal uterine loops, irregular to lobed gonads, and larger eggs; and from P. acceptum in possessing a short esophagus, nondigitiform vitelline lobes, and an oral sucker larger than the acetabulum. An annotated checklist of trematodes parasitizing P. pulchrum is given.

Stages In Corporate Stability And The Risks Of Corporate Failure, Richard C. Edwards

Department of Economics: Faculty Publications

Few would deny that the U.S. economy is today dominated by huge corporations. Much recent writing has proposed that these corporations form a stable and monopolistic (or oligopolistic) "core" around which a more competitive "peripheral" sector exists. Firms in the core are said to be "eternal," while firms in the periphery demonstrate the mortality and high turnover expected in competitive industries. In another context, Paul Baran and Paul Sweezy emphasized the permanence of big corporations when they noted:

The real capitalist today is not the individual businessman but the corporation. .. . The giant corporation of today is an engine …

Platyhelminths Of Nebraska Turtles With Descriptions Of Two New Species Of Spirorchiids (Trematoda: Spirorchiidae), Daniel R. Brooks, Monte A. Mayes

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Twenty-one species of platyhelminth parasites are reported from 8 species of turtles collected in Nebraska. Two species of spirorchiids are reported as new. Vasotrema brevitestis sp. n. from Trionyx muticus and T. spiniferus differs from V. amydae Stunkard, 1926, in possessing a relatively shorter, more compact testis, postcecal length equal to one-fifth the body length, a cirrus sac which does not extend to the opposite cecum, and vitellaria composed of discrete follicles more restricted in distribution. Hapalorhynchus foliorchis sp. n. from Chelydra serpentina differs from H. gracilis Stunkard, 1922, in possessing a narrower oral sucker and larger acetabulum, a prominent …

Polygons Have Ears, G.H. Meisters

Department of Mathematics: Faculty Publications

We refer to a simple closed polygonal plane curve with a finite number of sides as a Jordan polygon. We assume the truth of the famous Jordan Curve Theorem only for Jordan polygons. (For elementary proofs see Appendix 2 of Chapter V of [4] or Appendix B1 of [5].) Three consecutive vertices V₁, V₂, V₃ of a Jordan polygon P = V₁V₂V₃V₄... V_nV₁ (n > 4) are said to form an ear (regarded as the region enclosed by the triangle …

Reproductive Efficiency Of Jerseys, Red Sindhis, And Crossbreds, R. E. Mcdowell, B. F. Hollow, J. K. Camoens, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Ten measures related to breeding efficiency were used for comparisons among pure Jerseys and Red Sindhis and crossbreds with ¾, ½, or ¼ European dairy inheritance (Brown Swiss, Holstein, or Jersey) at two locations. Jerseys and crossbreds were common to both herds with Sindhis only at Jeanerette. Means for age at puberty (first estrus after 12 mo) were 425 ± 4.2, 434 ± 6.9, 459 ± 6.9, 504 ± 14.1, and 717 ± 40.4 days for Jerseys, crosses of ¾, ½, or ¼ and Sindhi. The increase in age of puberty was additive but not entirely. The ¾and ½ tended …

Resonance Raman Scattering And Collision-Induced Redistribution Scattering In I2, D. L. Rousseau, G. D. Patterson, P. F. Williams

P. F. (Paul Frazer) Williams Publications

We report the first experimental observation of broad-banded re-emission resulting from quasi-elastic collisional transfer processes. The data may be interpreted by the general theory of scattering of monochromatic light in gases. The connection between this theory and one derived for solids is discussed.

Thank you very much, Heinz.

You know, this program has gone so well this morning, that it is with some trepidation that l even stand up.

My compliments to everybody here at the table who has been before this podium today.

Hans, I think this is the best organized, best presented program on which I have appeared in many, many months and, I have appeared on a lot of them.

I "take my hat off" to all of you.

Beyond that, I want to say to all of you, before I get into the substance of my remarks, that although …

Leaf Freckles And Wilt Of Corn Incited By Corynebacterium Nebraskense Schuster, Hoff, Mandel, Lazar, 1972, M. L. Schuster

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The new bacterial disease Leaf Freckles and Wilt (LFW) of corn (Zea mays L.) was first observed in 1969 on two farms in southcentral Nebraska. Since then it has spread to other areas in the state. LFW is a serious disease on farms in six Nebraska counties (Clay, Custer, Dawson, Furnas, Hall and Phelps) and has been found in isolated cases in at least 28 other counties. In 1971 LFW was found in a seedcorn field in western Iowa, in 1973 in two Kansas counties, and in 1974 in South Dakota and Colorado. Because of its explosive nature, several …

Microfossils From The Big Springs Limestone (Pennsylvanian) In Nebraska, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

Sand-sized residues from partial acetic acid digestion of three samples of the Big Springs Limestone Member of the Lecompton Limestone (Pennsylvanian) from two localities in Cass County, Nebraska, have yielded sixteen genera of microfossils from five major groups of organisms and numerous other whole and partial fossils from seven other groups not identified to the genus level. These fossils include: Protozoa (fusulinids*); Porifera (one spicule type); Bryozoa (two undetermined genera); Brachiopoda (fragments); Gastropoda (two undetermined forms); Ostracoda (Bairdia*, Hollinella*, Moorites*, and one undetermined genus); Crinoidea (whole and partial ossicles*); Echinoidea (whole and partial spines and spine bases*); Holothuroidea (Achistrum …

Rbe-Dose Relations For Neutrons And Pions, Robert Katz, S. C. Sharma

Robert Katz Publications

RBE-Dose relations have been calculated from cellular radiosensitivity parameters and theoretical particle-energy spectra in tissue, of the secondary particles from neutron and negative pion irradiations. The theoretical results are compared with clinical and radiobiological data for normal tissue, tumors, and cells in culture. Formulae for calculation, cellular parameters, and the needed properties of equivalent “track-segment bombardments” are given, for several mammalian cells irradiated with pions and with neutrons of several energies.

Collections Of Recent Mammals In North America, Jerry R. Choate, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Mammalogy is the only systematic discipline that has previously undertaken periodic (that is, more than one) surveys of its holdings in North American collections. The first such survey (reported on by Howell, 1923) pertained to mammals in collections as of April of 1922. The report of the second survey (Doutt et al., 1945) summarized collections of mammals in North America as of 1943. The report of the third survey (Anderson et al., 1963) pertained to specimens of mammals in North American collections as of 1962. At that time, it was assumed that to prepare an updated report on North American …

Effects Of Anisotropic Electron-Ion Interactions In Atomic Photoelectron Angular Distributions, Dan Dill, Anthony F. Starace, Steven T. Manson

Anthony F. Starace Publications

The photoelectron asymmetry parameter β in LS coupling is obtained as an expansion into contributions from alternative angular-momentum transfers j_t. The physical significance of this expansion of β is shown to be that (i) the electric-dipole interaction transfers to the atom a characteristic single angular momentum j_t=l₀, where l₀ is the photoelectron's initial orbital momentum, whereas (ii) angular-momentum transfers j_t≠l₀ indicate the presence of anisotropic (i.e., term-dependent) interaction of the outgoing photoelectron with the residual ion. For open-shell atoms the photoelectron-ion interaction is generally anisotropic; photoelectron phase shifts …

The Differentiability Of AX, J. A. Eidswick

Department of Mathematics: Faculty Publications

A "from scratch" proof of the differentiability of a^x, a > 0, is avoided by essentially all modern-day authors. A slick and popular way of handling the problem is to define a^x as e^x log a its differentiability and other properties following from that of the functions e^x and log x. Unfortunately, the usual definitions of e^x and log x involve relatively sophisticated ideas (e.g., integration or power series). Furthermore, the student, having heard of e, the natural logarithm base, at an early stage of his development, is hardly enlightened when he is …
