Sedimentation Coefficients Of The Virions Of Soil-Borne Wheat Mosaic Virus, Myron K. Brakke

Department of Plant Pathology: Faculty Publications

The sedimentation coefficient of virion I of soil-borne wheat mosaic virus was estimated to be 219S, the same, within error, as the sedimentation coefficient of the dimer of virion II, estimated to be 218S. The monomer of virion II sedimented at 177S, and was 138 nm long. Another strain of the virus had a virion II (designated lIb) that was 92 nm long and sedimented at 159S. The two virus strains coexist in some fields.

Absence Of Spermine In Filamentous Fungi, Kenneth W. Nickerson, Larry D. Dunkle, James L. Van Etten

Papers in Microbiology

Polyamines were examined in several yeasts and filamentous fungi. Whereas putrescine, spermidine, and spennine were present in the yeasts, spernine was not detected in any of the filamentous fungi.

Absolute Doubly Differential Cross Sections For Ejection Of Secondary Electrons From Gases By Electron Impact. I. 100- And 200-Ev Electrons On Helium, M. Eugene Rudd, R. D. Dubois

M. Eugene Rudd Publications

We have measured absolute values of the cross sections for ejection of electrons from helium gas by 100- and 200-eV electrons. These cross sections were measured for emission angles from 10° to 150° and for electron energies from 3 eV to a value equal to the primary energy minus the ionization potential. The measurements were made using a static-gas target and an electrostatic analyzer. The resulting cross sections agree reasonably well with those of Opal, Peterson, and Beaty near 90°, but show the need for an adjustment of their angular distributions. Comparison with Born-approximation calculations of Manson et al. at …

A New Host For Pleistophora Ovariae (Microsporida), Glenn L. Hoffman, Mary L. Nagel

United States Fish and Wildlife Service: Publications

Pleistophora ovariae, a microsporidan parasite that infects ovaries of the golden shiner (Notemigonus crysoleucas), is a widespread problem for minnow culturists. It occurred in shiners held at 45 of 49 commercial fish farms inspected by Summerfelt and Warner (1970, Journal of Wildlife Diseases 6: 457-465). This microsporidan causes considerable damage to golden shiner ovaries, reducing fecundity, but most fish farmers obtain an adequate supply of eggs from young fish (1 or 2 years old) in which ovarian damage is not yet extensive.

Proceedings Of Perdix I: Hungarian Partridge Workshop, The Wildlife Society, Central Mountains And Plains Section, The Wildlife Society, North Dakota Chapter, North Dakota Game And Fish Department

Galliformes Specialist Group and Affiliated Societies: Conference Proceedings

Perdix I has succeeded in its major objective of bringing Hungarian partridge research and management people together in one place for introduction to one another and for a mutually beneficial exchange of information. A major communications bridge has been gapped by the informalization that occurs with the development of face-to-face relationships, a realization of how similar everyone's technical problems are, and an expression of concern regarding the need to develop work plans and guidelines to help direct future research and management by avoiding unnecessary duplication that often occurs with poor communications. As regards communications, it is refreshing to know that …

A Taxonomic Investigation Of Some Rhizomatous Species Of The Genus Muhlenbergia (Gramineae), James Kurtz, David M. Sutherland

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Seven species of the grass genus Muhlenbergia were studied using gross morphological and anatomical characters. The anatomical criteria proved to be of limited taxonomic value. A key to the species of the east-central plains was developed.

The genus Muhlenbergia is a large, widely distributed group of grasses, encompassing numerous species and various growth forms. The subgenus Muhlenbergia, comprised of mesic, broad-leaved, usually rhizomatous species, can easily be separated from the rest of the genus on the basis of growth habit and habitat preferences (Pohl, 1969). Species of the subgenus are widely distributed in North America but are most abundant …

Calcium Carbonate Inclusions In Pottery: Some Cautions For The Archaeologist, Raymond Leicht

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Studies of original firing temperature of pottery based on thermal properties of calcium carbonate and cultural inferences about potters' capabilities derived from such studies must be examined in the context of other intervening variables. These variables include original firing atmosphere, length of firing, size and concentration of the carbonate inclusions.

Carnivores From The Jamber Local Fauna (Pliocene, Valentinian), Boyd County, Nebraska, Karen Kreycik Messenger, Charles L. Messenger

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Five types of carnivores have so far been recognized in the preliminary study of the Jamber Local Fauna (University of Nebraska State Museum Collecting Locality Boyd County no. 6), northern Nebraska. These include Tomarctus cf. brevirostris, Aelurodon haydeni, Aelurodon sp., Leptocyon cf. vafer, and Pseudaelurus cf. marshi The Jamber Quarry carnivores and associated fauna appear to be Early Valentinian in age.

Chromosome Analysis Of Bidens Polylepis And Bidens Coronata (Compositae), Merlin G. Butler, Ronald R. Weedon

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The closely related species Bidens coronata (L.) Britt. and B. polylepis Blake are morphologically similar and may hybridize readily. Sympatric eastward, the species are allopatric in Nebraska-and adjacent states. Karyotype analysis of the two species revealed not only a number of similarities but also some significant differences. Chromosomal analysis of the awn forms of B. polylepis (designated as varieties by some) revealed no significant differences, indicating, along with morphological evidence, that B. polylepis is- a single taxonomic entity, although phenotypically highly plastic.

Drought And The Model Of A Quaternary Terrace-Cycle, C. Bertrand Schultz, Thompson Mylan Stout

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The concept of a "terrace-cyole" in the Quaternary history of the Central Great Plains was fust proposed by us at the 1944 "Symposium on Loess," sponsored by 1his Academy (1945). However, certain aspects have never been fully presented, particularly (a) the relations of drought to this "terrace-cycle" concept and (b) as a recurrent phenomenon in this and similar continental regi,pns. There also may be a possible relation to the fixation of sodium salts in vegetation and to selenium and nitrogen poisoning. Prediction requires scientific data not only from the near past, but also from the distant past. It is now …

Enargeia: A Concept For All Seasons, Dennis R. Bormann

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Aristotle, writing in the fourth century B.C., defined rhetoric as the "faculty of discovering in the particular case what are the available means of persuasion" (Aristotle, 1932, 1:2). He then proceeded to classify proofs intrinsic to the art of speaking into three modes-logos, ethos, and pathos. Consistent with his ''scientific'' point of view, he deplored writers of the arts of speaking who ignored argument; and his treatise emphasized the logical element in persuasion. As he said, persuasion is "effected by the arguments, when we demonstrate the truth, real or apparent, by such means as inhere in particular …

Kant As Internalist: The Synthetic A Priori Proposition Of Kant's Ethical Theory, Nelson T. Potter

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Kant claims that his categorical imperative is a synthetic, a priori proposition, but he does not make clear what makes this proposition synthetic or a priori. In this essay it is argued that in Kant's view the proposition is synthetic a priori because it states a quasi-psychological fact: that rational beings are capable of acting from purely moral motives. This means that Kant is an "internalist" in W.D. Falk's sense.

Preliminary Post-Cranial Metric Analysis Of Mammoths From The Hot Springs Mammoth Site, South Dakota, Barbara Lee Dutrow

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Salvage investigations of a Karst depression containing more than nine Late Pleistocene mammoth were conducted during approximately twenty field days in the summers of 1974 and 1975. The deposit contains a local death assemblage of a mammoth population. A post-cranial metric analysis has been conducted on the fossil elephant remains.

Sandhill Crane Dancing During The Spring Migration, James R. Gray, Thomas F. Sweeney

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The role, intensity, and frequency of Lesser Sandhill Crane (Grus canadensis) dances were interpreted from observations of 1,167 dance sequences from March 6, 1975, to April 15,1975. The observations were from 27 sites in Kearney and Hall Counties, Nebraska.

Nineteen variables, selected as possible determinants of dance frequency (dances/minute), were recorded on field observation forms along with a description of each dance and the approximate duration.

The 19 variables were regressed against the dance frequency of the total dances as well as 6 subgroups-courtship display, emotion or tension-release, aggression-related activity, pre-flight and pre-walk communication, and response to possible …

Some Aspects Of Lithification In Chalk, Nagaraja Kirumakki

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Chalk is affected by different diagenetic processes in comparison with other carbonate rocks. Commonly observed lithification processes are pressure-solution and reprecipitation and neomorphism. The first process is divisible into: (a) spot-welding or welding; (b) overgrowth; (c) stylolitization and cementation. Further, pressure-solution and reprecipitation is dependent on (a) geostatic pressure and (b) the ratio of Mg/Ca in the pore fluid. Overgrowth of calcite cement is controlled by the size and shape of the biogenic crystals. Neomorphism is also important in diagenesis. Neomorphic process dominates when pressure-solution process is ineffective. Organic and insoluble residue content dictate neomorphism. In conclusion, pressure-solution or neomorphism …

The Antiquity Of Bison Latifrons (Harlan) In The Great Plains Of North America, C. Bertrand Schultz, John M. Hillerud

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

There is abundant evidence available which strongly supports the Middle Pleistocene (Sheridanian) stratigraphic position of the fossilized remains of Bison latifrons (Harlan) in the Great Plains of North America. This would place the geologic age of this giant beast as post-Kansas to Early Illinoian. Fourteen localities, where the bones of B. latifrons have been found in the central part of North America, have been examined for stratigraphic and geomorphologic evidence.

The General Form Of The New Riddle Of Induction, Edward F. Becker

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Nelson Goodman has maintained that a definition of confirmation which does not include a criterion of law-likeness will allow the "confirmation" of any prediction whatsoever on the basis of any given body of data. Unfortunately, Goodman does not give an argument for this claim, but contents himself with illustrating it by examples. This paper supplies the argument which Goodman did not give, and thus shows that his claim is justified. My argument brings out what is essential to the construction of "grue"-type predicates, and thereby clarifies the nature of "the new riddle of induction."

The History Of Agriculture In The United States Beginning With The Seventeenth Century, Elvin F. Frolik

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The purpose of this paper is to summarize important historical developments in agriculture in what is now the United States, from the earliest colonial times to the present. In terms of the length of time of human history on this world, this period is so short as to seem almost insignificant. However, in terms of progress, the situation is the opposite-more has been accomplished in agriculture in this fraction of a millennium than in all previous history combined.

Agriculture, under immigrant settlers in what is now the United States, had its beginnings in the seventeenth century. The thirteen original colonies …

The Nature And Function Of Fundamental Propositions In Accounting Theory Construction, Jack L. Krogstad

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Accounting scholars such as Chambers, Ijiri, Mattessich, Moonitz, and Sterling emphasize the central importance of fundamental propositions in accounting theory construction. Theory building in accounting has proceeded, however, without the insight provided by delineation of the respective natures and functions germane to different types of fundamental propositions. Accounting theorists have not gone far enough in identifying the unique roles of the various statements used as basic assumptions in theory construction. Accordingly, premises, axioms, and postulates are differentiated in harmony with philosophic substance. Premises are closely linked to systems of formal deductive logic and the inherent processes of valid inference. Axioms …

Wood Duck Production In The Salt Creek Watershed Of Eastern Nebraska, Calvin L. Cink

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Counts of Wood Ducks made during the spring and summer of 1970 on the creeks and reservoirs of the Salt Creek watershed in southeastern Nebraska yielded a conservative estimate of 40 breeding pairs; 16 broods were counted. Estimates of production are biased by numerous variables, including intrinsic sampling problems.

Use Of Multicorporate F Reorganizations To Carry Back Net Operating Losses: Rev. Rul. 75-561, 1975-2 Cum. Bull. 129, Thomas N. Lawson

Nebraska Law Review

A corporate reorganization involving the transfer of the assets of one or more corporations to another corporation often raises questions regarding the ability of the transferee corporation to carry back postacquisition net operating losses under Internal Revenue Code section 172 to the preacquisition taxable years of the transferor corporations. This note more fully examines the provisions and significance of Revenue Ruling 75-561 regarding F reorganizations. The discussion is divided into three parts: (1) a brief historical overview of the case law that gave rise to Revenue Ruling 75-561; (2) an examination of the provisions of the ruling; and (3) an …

Withdrawal Of Pleas In Nebraska: The Rejected Plea Bargain: State V. Evans, 194 Neb. 559, 234 N.W.2d 199 (1975), Rick L. Ediger

Nebraska Law Review

This Note deals specifically with one particular aspect of the plea bargaining process in Nebraska: whether a criminal defendant has the right to withdraw a plea of guilty or nolo contendere entered pursuant to a plea bargain. In State v. Evans, the Nebraska Supreme Court held that not only is there no right to withdraw a guilty plea entered upon a plea bargain, but, absent a manifest injustice, it is improper for a trial judge to permit the withdrawal of a plea of guilty. This Note discusses the implications of this decision and examine alternatives which merit serious consideration.

Long-Run Economic Loss: Conflicting Interests Of Class Members: Blankenship V. Omaha Public Power District, 195 Neb. 170, 237 N.W.2d 86 (1976), Bradley D. Holtorf

Nebraska Law Review

In order to maintain a class action in either the state or federal court system, the representative party must fairly and adequately protect the interests of the other class members. It is axiomatic that a representative cannot adequately protect the interests of the class if his interests are antagonistic to or in conflict with those of the class he purports to represent. The Nebraska Supreme Court in considering the issue of adequacy of representation has applied an economic standard to determine when there is a conflict of interest within a class. In Blankenship v. Omaha Public Power District the court …

Joinder Of Criminal Offenses In Nebraska: Judicial Discretion V. Fair And Impartial Trial: State V. Nance, 197 Neb. 95, 246 N.W.2d 868 (1976), Lavern Holdeman

Nebraska Law Review

In State v. Nance, the Supreme Court of Nebraska, over the dissent of Justice McCown, held that two or more separate criminal offenses may be joined in the same information and indictment, and tried in the same proceeding when the offenses charged are of the "same or similar character." Although the defendant in Nance moved for severance of the offenses, the supreme court held that the trial court had complete discretion in deciding whether to grant or deny such a motion absent a showing of "actual" prejudice to the defendant. In applying such a strict rule on severance, the …
