Influence Of Various Factors On Aggregation Of Peorian Loess By Microorganisms, T. M. Mccalla, Francis A. Haskins, E. F. Frolik

Department of Agronomy and Horticulture: Faculty Publications

Soil structure is important in the attainment of adequate aeration for the aerobic microorganisms whose activities maintain such higher plant nutrients as sulfur, phosphorus, and nitrogen in a highly oxidized and thus readily available state. Good soil structure is also necessary for soil and water conservation, Under Nebraska conditions microorganisms and their decomposition products constitute a major source of soil-aggregating agents. The decomposition of crop residues and plant roots is important in the nutrition of these aggregating microorganisms. Other microorganisms, however, also utilize crop residues and plant roots, and they may decompose the aggregating agents as well, so that the …

Fluorometric Assay Of Free And Bound Coumarin Rn Sweetclover, Francis A. Haskins, Herman J. Gorz

Department of Agronomy and Horticulture: Faculty Publications

Free and bound coumarin are extracted by autoclaving leaf tissue in water. Free coumarin is determined directly from an aliquot of the water extract diluted in alkali. Additional autoclaving of the extract in concentrated alkali is required for release of the coumarin from the bound form, permitting an assay for total coumarin. Bound coumarin values are then obtained by difference. Results of the assay as applied to four different phenotypes of sweetclover are given.

Correlation Between Grades In Engineering Physics And Performance In Engineering Curricula, Donald Hoyt, Louis D. Ellsworth, Robert Katz

Robert Katz Publications

A survey of grades in Engineering Physics I at Kansas State College showed that the inner structure of the course was highly consistent. The correlation coefficient between the average of the first three tests and the final grade was about 0.88. More significantly, valuable prognostic data could be obtained from the final grade in the course. The correlation coefficient between the Engineering Physics I grade and the final grade point average of students who completed the course was about 0.83. Only 21% of the students initially failing the course successfully completed an engineering degree, while about 75% of the A, …

Observations On Shipleya Inermis Fuhrmann, 1908 (Cestoda: Acoleidae), Marietta Voge, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Shipleya inermis, described by Fuhrmann (1908) and redescribed by Baer (1940), is known from only few specimens. The first and only North American record of this species was published by Webster (1951), who reported the finding of two specimens in dowitchers. Examination of a large number of cestodes from dowitchers collected by Rausch, and of cestodes from the Helminthological Collection of the United States National Museum yielded specimens which are without doubt Shipleya inermis. However, some of our observations which are reported here do not agree with Baer's description. In particular, we are unable to agree with Baer …

Stream Pollution- Aquatic Macro-Invertebrate Communities As Indicators Of Organic Pollution In Lytle Creek, Arden R. Gaufin, Clarence M. Tarzwell

United States Environmental Protection Agency: Publications

Year-round field studies of the com position and ecology of stream communities associated with the purification of organic wastes in streams were initiated on Lytle Creek in October, 1949. This creek, which is located about 45 miles northeast of Cincinnati, Ohio, is a tributary of the Little Miami River. Its drainage basin comprises 27 sq. mi., a third of which is contained within the city limits of Wilmington, Ohio, a city of some 7,412 persons

Studies On The Helminth Fauna Of Alaska. Xxvii. The Occurrence Of Larvae Of Trichinella Spiralis In Alaskan Mammals, Robert L. Rausch, B. B. Babero, Virginia R. Rausch, Everett L. Schiller

Harold W. Manter Laboratory of Parasitology: Faculty Publications

In 1948 much interest in trichinosis in arctic regions was aroused, particularly by the findings of Thorborg et al. (1948), who investigated serious outbreaks occurring among the Eskimo of West Greenland during 1947. Consequently, with the founding of the Arctic Health Research Center in the autumn of 1948, a study of trichinosis in Alaska was the first project to be initiated by the Zoonotic Disease Section (formerly Animal-borne Disease Section) of this Center.

Field work was begun in January, 1949, and a preliminary note on trichinosis in Alaskan mammals was published by Brandly and Rausch (1950). The subject of trichinosis …

Waterfowl Sex Ratios During Spring In Washington State And Their Interpretation, Paul A. Johnsgard, Irven O. Buss

Papers in Ornithology

Sex-ratio studies have received much attention from research workers in recent years. The contributions of Hochbaum (1944), Petrides (1944) and others have yielded considerable information on sex ratios in waterfowl; Beer (1945) and Yocom (1949) have presented data for the state of Washington. To interpret regional data on waterfowl sex ratios adequately, it is necessary to obtain a series of uninterrupted observations covering the entire migration period of the species concerned. In 1954, an ecologic study was conducted in the Potholes area, Grant County, central Washington (Johnsgard, 1956). During the period February 15 to May 16, sex-ratio data were collected …

Grasslands Of The Great Plains: Their Nature And Use, J. E. Weaver, F. W. Albertson, B. W. Allred, Arnold Heerwagen

Papers of John E. Weaver (1884–1956)

This book is the result of a long-felt need by the authors and their students for a comprehensive survey of the numerous studies that have been made on plains grasslands. From southern Texas far into Saskatchewan the mid and short grasses form a magnificent prairie nearly 2,500 miles in length and approximately 400 miles wide. Kinds of communities, their composition, nature, significance and uses are fully described. Such information is of value not only to students, range technicians, and other professional conservationists, but also to ranchers and other land owners-in fact, to anyone interested in the economy of our midwestern …

Ostracoda Of The Silurian Decker And Manlius Limestones In New Jersey And Eastern New York, Frank M. Swartz, Frank C. Whitmore Jr.

United States Geological Survey: Staff Publications

Descriptions and illustrations are given for 44 ostracode species of the Decker, Rondout and Manlius limestones of the William Nearpass quarries and Dalton Nearpass farm in northwestern New Jersey, and at Austin's Glen and Trilobite Mountain in New York. One brachiopod variety is proposed. The ostracode species are distributed through 11 families and 23 genera. Thirty-two species and one variety are new, and there are eight new genera. Holotype or syntype specimens of 13 of Weller's ostracode species have been restudied and are refigured and redescribed. Stratigraphic sections are described to provide details of the ostracode occurrences, and zonal potentialities …

The Life Cycle Of Crassiphiala Bulboglossa (Trematoda: Strgeida): Development Of The Metacercaria And Cyst, And Effect On The Fish Hosts, Glenn L. Hoffman

United States Fish and Wildlife Service: Publications

The adult of Crassiphiala bulboglossa was described by Van Haitsma (1925) from the kingfisher, Ceryle alcycon. It can be differentiated from Uvulifer ambloplitis (Hughes, 1927), apparently its closest relative in North America, by the presence of a large bulbous holdfast occupying most of a cup-shaped forebody, and the absence of a ventral sucker. In U. ambloplitis the holdfast is small, the forebody is not cupped, and a ventral sucker is present. These species can be readily identified with the keys given by Dubois (1953).

Early Ceramic Period Sites In Northeastern Nebraska, Raymond S. Price

Department of Anthropology: Theses and Student Research

The Central Plains has become an increasingly important  area of archeological research during the last half century.  The major culture complexes have been identified, the chronological sequences of these cultures have been determined, and  the general framework or Central Plains prehistory has been  outlined. Three main time periods are recognized for the Central Plains on the basis of a combined stratigraphic and  dendrochronological study (Ohampe, 1946). These three general  time divisions are, identified as beginning with the oldest: the Lithic, the Ceramic, and the Historic Periods. The Ceramic Period is further divided into the Early, Middle, and  Late divisions. The …

Flight Path Of Least Time, Robert Katz

Robert Katz Publications

A problem which one might assume to be of considerable practical interest, but certainly a problem to arouse the curiosity of the undergraduate student, is the problem of determining the most economical flight path of an airplane in the presence of known winds. In general one must assume that the wind system between source and destination is a complex one involving circulation about several centers with winds of variable speed and direction. The geodesic between source and destination is clearly not the flight path of least time in the presence of winds, nor is a cursory examination of a weather …

Effects Of Irradiation, Maleic Hydrazide, Temperature, And Age On Enzyme Activity In Seedlings Of Corn (Zea Mays L.), Francis A. Haskins, Harold Chapman

Department of Agronomy and Horticulture: Faculty Publications

The work of Schmidt and Frolik (1951) and of Beard (1955) has shown that plants of corn (Zea mays L.) grown from seeds treated with appropriate doses of X-rays or thermal neutrons are greatly reduced in stature and survival in comparison with control plants, and that pronounced increases in chromosomal abnormalities and pollen sterility also result from seed irradiation. It is reasonable to suspect that these morphological and cytological effects might be associated with changes in the metabolism of the plant. Accordingly, a series of experiments has been conducted in which preparations of normal corn seedlings and preparations of …

God And Caesar In Nebraska: A Study Of The Legal Relationship Of Church And State, 1854 -1954, Orville H. Zabel

University Studies (University of Nebraska) (1888–1984)

At a time when the control over the relationship of church and state seems to be shifting from the state governments to the Federal Government, it was decided to undertake a case study of the church-state problem in Nebraska. Such a study, stretching over a century, appeared to make possible a contribution to the understanding and solution of problems which have recently gained prominence and which will probably appear frequently in coming years. Any contribution, however slight, to an understanding of what constitutes the most desirable relationship of the church and the state may be of considerable value. Such a …

Occurrence And Distribution Of Hymenolepidid Cestodes In Shrews, Marietta Voge, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A survey of the literature dealing with cestodes of shrews reveals the increasing interest of contemporary parasitologists in this poorly known group of symbionts. In the United States, approximately 18 species have been described from shrews in the last 15 years. These reports deal almost exclusively with morphology of the cestodes; however, information on distribution, host specificity, rate and intensity of infection, is either fragmentary or not available in published form.

Settlement In The Santa Cruz Area: A Proposed Program For The Development Of An Area With European Immigrants And Bolivian Indians, Ernesto Wende-Frankel

Open Access Master's Theses (through 2010)

Introduction

This study involves conceptual analysis in a broad interpretation of the term of a public administration problem situation embracing cultural, as well as politico-economic factors. A program ot action is recommended in considerable detail, calling tor the settlement of colonists to develop agriculturally a large amount of Bolivian land that promises to become, with proper husbandry, highly productive.

The author is a Bolivian agricultural economist who is making public administration his career, with particular emphasis upon the efficient utilization or land--and manpower, which for sometime past in his native country has been poorly organized and under employed. During the …

A Survey Of The Effects Of Changes In PH, Solvent And Salt Concentration Upon The Rate Of The Periodate-Glycol Reaction, Jay E. Taylor, Benadetto Soldano, George A. Hall

Department of Chemistry: Faculty Publications

A quantitative study of the effect of the periodate- glycol complex upon the rate of the periodate-glycol reaction was made in an earlier paper. The data for the present paper were taken before those of the previously published paper and, for the most part, before the importance of the periodate-glycol complex had been recognized. It has not been possible therefore to interpret the present data with the degree of thoroughness of the earlier paper. However, certain very interesting conclusions can be made.
The Effect of Variation of pH.
Effect of Changes in Solvent.
The Effects of Certain Salts.
