A Noise Figure Lower Bound And A Frequency Converter, Grant Myers

Department of Electrical and Computer Engineering: Faculty Publications

This article establishes a lower bound for the noise figure of two networks in cascade. This is illustrated by means of a passive low-level frequency converter which utilizes a back diode as a nonlinear conductance. Other investigators have analyzed the properties of low-level frequency converters. However, the greatest lower bound of a combination of the converter and intermediate frequency amplifier system was not considered previously and is the subject of this paper. Knowledge of this lower bound has practical significance because if a measured value of noise figure is less than this lower bound, it follows that the measurement is …

Digenetic Trematodes Of Marine Teleost Fishes From Biscayne Bay, Florida, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

This study includes 111 species of Digenea from 69 of 113 species of teleost fishes examined from Biscayne Bay, Florida. Biscayne Bay represents the reported northern limit along the Atlantic coast for all but 22 of the 111 species. It represents the southern limit for only one, Didymocystis scomberomori. From the known collections reported in the literature, the Digenea from Biscayne Bay appear to consist primarily of a tropical fauna. Species previously known from the Pacific Ocean only are Botulisaccus pisceus and Pseudocreadium scaphosomum. There are 81 new host records.

Two new genera are created: Claribulla (Felloclistomatidae) and …

The Chemistry Of Pesticides, Walter R. Benson

United States Food and Drug Administration: Publications

Introduction

This review is limited to the structures and a few reactions of the pesticides mainly insecticides-that affect mammalian systems and that are the subject of papers by other authors in this monograph. There is no attempt to give a complete review of the chemistry of pesticides. It is intended only to show the breadth and depth of pesticide chemistry through the use of examples. With proper use of the references, and of the papers by Crosby, Freed and Montgomery, and Owens in this monograph, the reader will be able to find information for other chemicals.

Lattice Dynamics And Second-Order Raman Spectrum Of Naf, John R. Hardy, A. M. Karo, I. W. Morrison, C. T. Sennett, J. P. Russell

John R. Hardy Papers

The second-order Raman spectrum of NaF has been measured using an argon laser source. For a light beam incident along the [010] direction, polarized along the [001] direction, and viewed along the [100] direction, the scattered radiation is almost completely polarized. It is shown theoretically that it is possible to account for the polarization and the detailed shape of the observed spectrum within the experimental resolution using a Raman polarizability tensor whose second derivatives with respect to nuclear displacements depend only on the positions of first neighbors in the crystal, provided one uses the phonon frequencies derived from a deformation …

The Biology And Ecology Of Trogoderma Glabrum (Herbst) In Stored Grains, Benjamin H. Kantack, Robert Staples

Nebraska Agricultural Experiment Station: Historical Research Bulletins

These investigations were undertaken to determine the distribution and importance of Trogoderma glabrum (Herbst) in stored grain in Nebraska, the ecological factors favoring population increase in stored wheat, corn, and sorghum, and the role T. glabrum might play in disseminating internally the Aspergillus molds commonly encountered in stored grain.

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 …

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 …

A New Rhinoceros From The Nebraska Miocene, Lloyd G. Tanner

Bulletin of the University of Nebraska State Museum (1924–2023)

A new species of rhinoceros, Menoceras marslandensis, is here proposed. It is based upon a nearly complete skull from the upper part of the Marsland Formation, Hemingford Group (Miocene), of Box Butte County, Nebraska. The new species was probably derived from Menoceras arikarense (Barbour), collected from the Agate Springs Quarries (Arikaree Group, Harrison Formation) of Sioux County, Nebraska, with which both Diceratherium niobrarensis Peterson and D. cooki Peterson are likely synonymous. From Menoceras arikarense, the presumed ancestral stock, Menoceras marslandensis differs in possessing the following characters: (1) very long, fused but slightly cleft, nasals, with flattened, rugose areas …

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 …

On Algebras Of Finite Representation Type, Spencer E. Dickson

Department of Mathematics: Faculty Publications

Since D. G. Higman proved that bounded representation type and finite representation type are equivalent for group algebras at prime characteristic, there has been a renewed interest in the Brauer-Thrall conjecture that bounded representation type implies finite representation type for arbitrary algebras. The main purpose of this paper is to present a new approach to this conjecture by showing the relevance (when the base field is algebraically closed) of questions concerning the structure of indecomposable modules of certain special types, namely, the stable (every maximal submodule is indecomposable), the costable (having the dual property), and the stable-costable (having both properties) …

The continued growth of higher green plants well supplied with water and inorganic nutrients depends primarily on (i) the accomplishment of photosynthesis in the leaves and (ii) the transport of organic compounds from the leaves to heterotrophic cells which constitute metabolic sinks.

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.

Gaseous Exchange In Crop Stands, Edgar Lemon

Department of Agronomy and Horticulture: Faculty Publications

Man through the ages has evolved a strategy, albeit empirical, of manipulating the environment and the plant to his advantage. Practices such as fertilizing the soil, irrigation, weed control, and plant breeding and selection are common. Nonetheless, concentrated and coordinated efforts to understand the mechanisms controlling the whole soil-plant- atmosphere continuum is a new approach to finding new ways to favorably manipulate the whole system as well as predict response.
Conceptually and experimentally it has proven advantageous to view the total system in terms of energy, momentum, and mass exchange. This makes sense because in the first instance the foundations …

Environmental Manipulation For Higher Yields, Paul Waggoner

Department of Agronomy and Horticulture: Faculty Publications

My role in this chapter on environmental manipulations is making a prediction that can be used until experiments render the final verdict.
In chapters preceding mine, an array of physical and physiological phenomena for affecting yield has been laid before the grower of plants. Predicting whether environmental manipulation will increase yield requires that all of these phenomena be considered for foreign lands are littered with the bleaching bones of immigrant varieties and practices that were ambushed by an unsuspected environmental difference.
Interaction is the Scylla of biologic prediction. Formerly we predicted by drawing a curve or writing a formula relating …

Plant Morphology And Stand Geometry In Relation To Nitrogen, Robert F. Chandler Jr.

Department of Agronomy and Horticulture: Faculty Publications

During the past decade, the importance of plant morphology and spacing in relation to nitrogen responsiveness in terms of crop yield has been increasingly recognized, particularly in the case of the cereal grains.
It is the purpose of this paper to present examples of experimental results obtained by rice research workers which support certain significant principles. Although this treatise will be confined to the rice plant (Oryza sativa L.),as Wittwer (1968) points out, the principles elucidated are applicable to many other crops, and particularly to the small grains, such as wheat (Triticum aestivum L.), oats (Avena sativa …

From The Editors

Nebraska Law Review

It has been said that the legal profession as it exists in Nebraska is irrelevant to the real problems and needs of our society. The editors are not entirely in agreement with that statement, for it is through the practice of law, as it exists, that the needed changes and reforms must come about. However, before the long-range objectives can be obtained, indeed, before they can even be subjected to attack, the short-range goals demand attention. Only if the attorney is well trained can he hope to contend with the dimensions of today's problems in our complex society. Only if …

Ionic Transport In Potassium Chloride, Robert Fuller, Charles L. Marquardt, Michael H. Reilly, John C. Wells Jr.

Robert G. Fuller Publications

The electrical conductivity and chlorine ion diffusion in KC1 and KCl:SrC1₂ single crystals have been analyzed by least-squares methods, using as a model a perfect crystal perturbed by five defects: isolated anion vacancies, isolated cation vacancies, divalent cation impurities, divalent cation-impurity-cation-vacancy complexes, and vacancy pairs. The transport equations were derived from this five-defect model using a simple theory for noninteracting particles, except for the nearest-neighbor binding to form complexes and vacancy pairs, and using the same theory including long-range Coulomb interactions between the isolated defects. This latter theory yielded the better description of the experimental results. However, the analyses …

Zoonotic Diseases In The Changing Arctic, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Compatible with the biotic uniformity of northern regions, the occurrence of certain organisms which cause zoonotic diseases is general throughout the Arctic. In the past, most frequently affected by such diseases have been aboriginal peoples whose way of life involved encroachment upon naturally occurring parasite-host assemblages. Now, as changes take place in socioeconomic conditions in the Arctic, the importance of zoonotic diseases as a cause of morbidity may lessen among such peoples, but on the other hand, more nonaborigines may be affected. Although my remarks relate mainly to Alaska, again the biotic uniformity of the North seems to have its …
