A Gering Formation (Miocene) Pumice Conglomerate And Associated Beds From Broadwater, Nebraska, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

The Mitchell Pass Member of the Gering Formation was defined by Vondra, Schultz, and Stout in 1969 on the basis of exposures in the Wildcat Ridge area of western Nebraska. The basal part of the member in many areas of Wildcat Ridge is a pumice-pebble conglomerate bed. A newly discovered pumice-pebble conglomerate locality occurs north of Broadwater, Nebraska, some twenty miles east of the easternmost previously reported exposure of the pumice conglomerate at Redington Gap on Wildcat Ridge. Pumice samples from Redington Gap and Broadwater have the same index of refraction and similar inclusions. Beds above the conglomerate and below …

Reflection Of An Electromagnetic Plane Wave With 0 Or Π Phase Shift At The Surface Of An Absorbing Medium, R. M.A. Azzam

Electrical Engineering Faculty Publications

An electromagnetic plane wave incident obliquely from a transparent medium onto the surface of an absorbing medium can be reflected with 0 or π phase shift if (i) the wave is p (TM) polarized, and (ii) the complex relative dielectric function ε is such that 0 ≤|ε| ²/2Re(ε) ≤ 1. Furthermore, the locus of ε such that the reflection coefficient for the p polarization is real at the same angle of incidence, is a circle, and that of ε^½ (the complex relative refractive index) is Bernoulli’s lemniscate.

Temperature Dependence Of Alignment Production In He I By Beam-Foil Excitation, Timothy J. Gay, H. G. Berry

Timothy J. Gay Publications

We have measured the dependence upon target-foil temperature of the linear polarization fraction (M / I) of the 2s¹S-3p¹P, 5016-Å transition in He I for ion energies between 60 and 180 keV. The thin carbon exciter foils were heated externally by Nichrome resistance elements. The measurements of Hight et al. are duplicated; the energy and current dependencies of M / I are the same, assuming correspondence between beam heating and external heating. We also observe that γ, the number of secondary electrons produced per incident ion, decreases with increasing foil …

Magnetic Properties Of The Rare-Earth Glasses (R65Fe35)100-XBX, J.A. Gerber, S.G. Cornelison, W.L. Burmester, David J. Sellmyer

David Sellmyer Publications

Results are reported on the magnetic properties of (R₆₅Fe₃₅)_100-xB_x glasses, where R denotes Y, Gd, and Er, and x is 10 or 20. Curie-Weiss fits were made to high temperature susceptibility data to determine average effective moments per magnetic ion and Weiss temperatures. Hysteresis loops and modified Arrott plots were used to determine the spontaneous magnetizations, coercive forces, and ordering temperatures. The effective moments and spontaneous moments are compared with those calculated on the assumption of local moments on both magnetic subnetworks, and assuming various spin structures. There is evidence for moment instabilities …

Study Of Indian Nuptiality., Chitta R. Malaker Dr.

Doctoral Theses

DEFINITION OF NUPTIALITYAccordi ng to the latest International Demographic Terminelogy (Grebeni k and ill, 1974), t he term 'nuptiality' is used to denote the whole subject of the formation and dissolutien of sexual uni ons, includi ng the study of marriage, consensual uni ons, separation, di vorce, widowhood etc. It is also used, in a narrower sense, as a synonym for marriage in such terms as nuptiality rates;and nuptiality probabilities, The study of nuptiality deals with the frequency of marriage, 1.e., unions between persons of opposite sexes which involve rights and obligations fixed by law and custom; with the characteriatics …

Theory Of Estimation In Algebraic And Analytic Exponential Families With Applications To Variance Components Models., Krishnan Unni Dr.

Doctoral Theses

There are many important statistical problems of the following kind. The family of probability measures O is parametrized by a vector parame ter n varying in a q-dimen- sional domain. P can be represented as an exponential family of probability distributions with k canonical para- me ters where k is greater than q. The canonical parameters do not vary in a domain in R, but are restricted by polyno- mial or analytic equations. They vary on a curved surface defined by the polynomial or analytic equations within the natural parame ter space of the exponential family. The present work is …

Doctoral Theses

The prime concem of economist: traditionally has been the system of markets and their role in rasource allocat on. Walrasian equilibrium theory, which is believed to províde an ajequate framework for resource allocation through markets, has been extensively analysed in the recent past. At the sane time, it has been realined, mainly throunh Keynesian influence, that the market machanism is prone to failures, DOwnward Inflezibility of wages is an obvious example of this. It is further possi that a central authority concerned with improving general welfare may tamper vith the market mechanism or do away with it altoer.Thered ar three …

Kinematics And Thermodynamics Of Nickel(Ii)-Glycine Complexes Using Carbon Magnetic Resonance, Donald Frederick Shepard

Chemistry and Chemical Biology ETDs

l- ¹³C glycine was studied in nickel(II) solutions using carbon magnetic resonance (CMR). The carboxy bound nickel(II)-glycine complex and the kinetics of complexation between aquated nickel(II) ion and aquated glycine are described. It has been hypothesized that solutions containing no complexation higher than the chelated mono nickel(II)-glycine complex contain five magnetically different glycine species. The effects of these five magnetically different glycine species on the CMR spectra of the nickel(II)-glycine solutions are discussed.

An Objective Forecast Method Developed For Lake Ontario Induced Snowfall Systems, K. F. Dewey

School of Natural Resources: Faculty Publications

A research effort was initiated in 1976 to develop an objective lake-effect snowfall forecast model for each of the Great Lakes. It is the purpose of this paper to present the development and evaluation of the forecast method which was created for the Lake Ontario induced snowfall systems. All Lake Ontario lake-effect days were identified for a 10-yead period prior to the 1976 snowfall season. Upper air surface observations were combined with overlake data for these lake-effect periods. The dominant predictors were derived through the diagnostic ability of stepwise multiple discriminant analysis. The final product of this research effort was …

The Status Of The Endrin Rpar, Kyle R. Barbehenn

Eastern Pine and Meadow Vole Symposia

The Agency's "Preliminary Determination" published in the Federal Register on November 2, 1978 proposed that the use of endrin to control voles in apple orchards be continued providing that several modifications in the label be made. What I would like to discuss briefly are (1) some of the bases for the decision, (2), one of the new requirements, and (3) comments received from the Office of Endangered Species, U.S. Fish and Wildlife service.

Embryo Rejection In The Pine Vole, Kenneth J. Marks, Margaret Horsfall Schadler

Eastern Pine and Meadow Vole Symposia

When a pregnant pine vole is placed in a cage with a strange (unfamiliar) male, one that did not cause her pregnancy, this female goes into "heat", indicating she has rejected the embryos she was carrying. This pine vole can later be impregnated by the strange, or second male. This phenomenon of pregnancy termination, called the "Bruce effect", was first noticed by Hilda Bruce, who saw it occur in labratory mice. Many investigators have noted it in a variety of labratory mice, deer mice, and other species of voles. We set out to see if the Bruce effect was reproducible …

Impacts Of Amended Pesticide Statutes On Requirements For Registration Of Products For The Control Of Voles In Orchards, William W. Jacobs, Raymond W. Matheny

Eastern Pine and Meadow Vole Symposia

The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) has recently been amended by the passage of The Federal Pesticide Act of 1978 (Public Law 95-396, passed September 30, 1978). While many aspects of the FIFRA have been amended, the changes of most immediate relevance to those interested in developing data in support of products used in the control of orchard voles are the authorities given the EPA Administrator to grant conditional registrations and to waive efficacy data requirements.

Dynamics Of A Pine Vole Population In A Pennsylvania Orchard, D. A. Simpson, R. G. Anthony, G. M. Kelly, G. L. Storm

Eastern Pine and Meadow Vole Symposia

Because of the lack of long-term studies on the population dynamics of pine voles in Pennsylvania orchards, a study intended to collect various population parameters was initiated in Adams County in November 1973 and continued until November 1977. Two orchards, 0.3 km apart, were chosen for study. Pine voles in Orchard A were live-trapped, and those in Orchard B were snap-trapped. Population density estimates were determined from capture-recapture data from Orchard A, and information on age structure, reproduction, and physical condition were recorded from necropsied voles from Orchard B. Both orchards were maintained and treated by orchard personnel with Endrin …

Vole Control With Volak Rodenticide, Dale E. Kaukeinen

Eastern Pine and Meadow Vole Symposia

Field trials with VOLAK rodenticide containing 50 ppm brodifacoum have been conducted in eight states and against four vole species during 1977-78. Hand baiting at 5-10 lb/A and broadcast applications at 10-20 lb/A gave more effective control than other products tested in most cases.

The Endrin Rpar, Lawrence S. Ebner

Eastern Pine and Meadow Vole Symposia

In July, 1976 the U.S. Environmental Protection Agency issued a "Notice of Rebuttable Presumption Against Registration and Continued Registration of Pesticide Products Containing Endrin" (41 Fed. Reg. 31,316). The purpose of this Notice was to initiate an "RPAR" review to determine whether continued usage of endrin, including the use of endrin for vole control, poses a "substantial question of safety" necessitating cancellation proceedings under Section 6(b) of the Federal Insecticide, Fungicide and Rodenticide Act ("FIFRA").

The Vole Control Program That Is Too Expensive, John E. Crumpacker

Eastern Pine and Meadow Vole Symposia

We have had some success for the past two years in controlling voles on a commercial scale at our orchards in Virginia. For years, vole control would vary from not acceptable to marginal control using various cultural methods and using ground sprays, such as Endrin and Chlorophacinone.

Preliminary Results Of Two Research Projects In New York, Jonathan Bart, Milo E. Richmond

Eastern Pine and Meadow Vole Symposia

In the fall of 1977, New York fruit growers in the state's Hudson Valley region were given a temporary permit to use endrin in an effort to curb an increasing vole damage problem. The approval of endrin for this use was the first such large scale release of a chemical in this class since the banning in 1971 of most chlorinated hydrocarbons in this state. With approval for limited use came the obligation to monitor the Hudson Valley region for 1) efficacy of the material, 2) non-target effects on aquatic and terrestrial wildlife and 3) persistence in the orchard environment. …

Results Of Pine Vole Control Studies In 1978, Ross E. Byers

Eastern Pine and Meadow Vole Symposia

Broadcast treatments of a number of anticoagulant baits were found to be effective for the control of pine voles in orchards. Rates necessary for good control were: Volak - 15 lbs/A; Bromodiolone 15 lbs/A; Rozol - 20 lbs/A; two applications of Ramik-Brown - 20 lbs/A each. At least 3 days of good weather appeared to be required for good vole control. Cellophane packeted baits of Volak placed at each tree in vole runways under cinder blocks gave excellent control. Bait remained in excellent condition for long periods of time or until opened by voles. An electromagnetic device was evaluated for …

Progress Report -- Experimental Comparison Of Vole Control Methods, Don W. Hayne

Eastern Pine and Meadow Vole Symposia

At last year's meeting in Beltsville, William T. Sullivan, Jr., read a paper describing an experiment we had set up to compare vole control methods (Sullivan and Hayne 1978). In particular, this investigation attempts to measure the effect of clean orchard culture. This year I am describing some of our experiences with this experiment, with a preliminary appraisal of the different methods of study. Obviously, our observations must be accepted as very tentative, made as they are so early in the experiment.

Impact Of Spacing Behavior And Predation On Population Growth In Meadow Voles, Dale M. Madison

Eastern Pine and Meadow Vole Symposia

Free-ranging, sexually mature meadow voles (Microtus pennsylvanicus) were tracked using radiotelemetry from June through August 1974, 1975 and 1978. Up to 20 voles were monitored concurrently to derive estimates of intraspecific spacing and natural predation in an effort to clarify processes involved in the limitation of population growth. The daily ranges of the males, as compared to those of the females, were larger, more variable in size, and changed location more from one day to the next. Adult females usually maintained territories free of other females; males overlapped considerably among themselves. Males temporarily moved into the areas occupied by estrous …
