Studies On The Helminth Fauna Of Alaska. Xi. Helminth Parasites Of Microtine Rodents--Taxonomic Considerations, Robert L. Rausch
Harold W. Manter Laboratory of Parasitology: Faculty Publications
A survey of the helminth parasites of Alaskan rodents has been carried on by the writer since the winter of 1948-1949, as a continuation of an investigation begun in the central United States in 1942. Results of this work indicate that, despite the size of the Territory of Alaska, the survey is complete enough to furnish a reasonable knowledge of the species of helminths parasitic in microtine rodents in Alaska. Information derived from previous investigations serves as a standard against which the completeness of the present work may be judged. In the writer's opinion, the continuation of this work on …

John Wesley Powell: Frontiersman Of Science, Paul Meadows
University Studies (University of Nebraska) (1888–1984)
I should explain that this book is more or less an accident. It started with a suggestion by my friend and former colleague, the late Joseph Kinsey Howard, that the Major was worth knowing. A Montana newspaperman and writer, Howard had been impressed by the amazing far-sightedness of Powell's report, published in 1878, on the arid lands of the West. At the time I was preparing a report of my own for a Rockefeller Foundation research project in the humanities. Upon reading the Major's study of the arid lands, it occurred to me that it would be profitable to review …

Chemical Reactions Near Equilibrium, W.R. Gilkerson, M.M. Jones, Gordon A. Gallup
Gordon Gallup Publications
In seeming contradiction to usual deductions from thermodynamics, it has been shown by De Donderi on the basis of his affinity function, by Prigogine2 on the basis of the Chapman- Enskog model, and by Manes, Hofer, and Wellers using purely mathematical methods, that the rate of a chemical reaction close to equilibrium is directly proportional to the free energy difference between reactants and products. This relation may be shown to be a consequence of the theory of absolute reaction rates, also.

Helminths From The Round-Tailed Muskrat, Neofiber Alleni Nigrescens Howell, With Descriptions Of Two New Species, Robert L. Rausch
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Two specimens of round-tailed muskrat, Neofiber alleni nigrescens Howell, were examined for helminth parasites. Four species, a trematode and three cestodes, were collected. Two of these, Quinqueserialis floridensis and Paranoplocephala neofibrinus, are described as new. Cittotaenia praecoquis Stiles, 1895, is recorded from this host, and larval cestodes are tentatively identified as Taenia lyncis Skinker, 1935.

Audio Census Of Some Wisconsin Game Birds, Donald R. Thompson, Charles W. Lemke
Audio Census Of Some Wisconsin Game Birds, Donald R. Thompson, Charles W. Lemke
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
Audio censuses of Wisconsin game birds were commenced in 1948, and now include the bobwhite quail, the pheasant and the ruffed grouse, in the order in which censuses were introduced.
Briefly, audio censuses are based on the characteristic sounds given by the male of the species concerned during the breeding season. An observer strategically located at a station, or stations in the field tallies the number of individuals calling, and/or the number of calls heard during a given time period.
In Wisconsin, only the transect method is used, with the observer following a given route and making listening stops of …
Red-Backed Vole With A Tick Attached Near Eyeball, H. L. Gunderson
Red-Backed Vole With A Tick Attached Near Eyeball, H. L. Gunderson
University of Nebraska State Museum: Mammalogy Papers
A red-backed vole (Clethrionomys gapperi), with a tick attached to or just under the inner corner of the eyelid at the canthus, was caught in a live trap on July 11, 1961. This is an unusual place of attachment and it is difficult to understand how the tick could have become attached at a point where it could easily be scratched off by either the forefoot or hind foot of the vole.

The Relationship Between Altitude – I.Q. Discrepancy And Anxiety, Claire Kepler Purcell, John Drevdahl, Kenneth Purcell
Department of Psychology: Faculty Publications
Recently there has been increasing interest in the use of intra-individual test discrepancies as a measure of functioning efficiency. One of the major problems in establishing scatter patterns has been that of finding a suitable internal reference point. The three reference points most commonly employed are the mean or IQ, the vocabulary score, and the altitude or maximum score. Psychologists who believe that the G factor is an ability argue for the use of the IQ as a reference point while those who believe that it is a capacity use altitude as a reference point. In regarding intelligence as a …

Insect Types In The Collections Of The University Of Nebraska State Museum, Martin H. Muma
Insect Types In The Collections Of The University Of Nebraska State Museum, Martin H. Muma
Bulletin of the University of Nebraska State Museum (1924–2023)
In 1948 the insect collections at the University of Nebraska State Museum were placed in the care of the author. Prior to that date curatorial duties were assumed or assigned to full time teaching or research staff members. As would be expected under the latter circumstances, the organization of study material and types was neglected in many families and genera. Since 1948 type material, because of its intrinsic value, has received considerable attention. All primary and representative secondary types have been assembled in three museum cases and one slide cabinet for curatorial and study convenience.

Radioactive Disintegration, Robert Katz
Radioactive Disintegration, Robert Katz
Robert Katz Publications
The conventional development of parent-daughter relationships in radioactive disintegration follows the treatment given in Rutherford, Chadwick, and Ellis in which a trial solution of the differential equations appropriate to the process is proposed, and the arbitrary constants are evaluated by application of boundary conditions. At the senior-graduate level at which the first course in nuclear physics is usually taught, the following derivation is believed to be considerably more instructive.
Studies On The Helminth Fauna Of Alaska. Vii. On Some Helminths From Arctic Marmots With The Description Of Catenotaenia Reggiae N. Sp. (Cestoda: Anoplocephalidae), Robert L. Rausch
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Among Alaskan mammals examined for helminthic parasites during 1950 was a series of marmots, Marmota caligata broweri Hall and Gilmore, 1934, from the Brooks Range, Arctic Alaska. The animals were collected a few miles south of Tolugak Lake (lat. 68° 24' N, long. 151° 26' W), and from the vicinity of Kanayut Lake, about 15 miles northeast of Tolugak Lake. This distinctive marmot has been hitherto represented in collections only by the three specimens comprising the type material. In addition to greatly extending the known range of this form, the collection of these specimens also contributes the first information on …

The Uranyl Nitrate-Water System Above 60°, W. L. Marshall, Jr., J. S. Gill, C. H. Secoy
United States Department of Energy: Publications
Although there are some data in the literature for the solubility of uranyl nitrate in water, the discrepancy of these data indicated the necessity for a check on the measurements. We have measured the solubility from the incongruent melting point of the hexahydrate at about 60° to the melting point of the dihydrate at 184°. Our results show a lower solubility than that given in most of the earlier data and also indicate an incongruent melting point for the trihydrate rather than the congruent point inferred in some of the previous work. The system is thermally stable up to the …

The Sedimentation Rate Of Potato Yellow-Dwarf Virus, M. K. Brakke, L. M. Black, Ralph W. G. Wyckoff
Department of Plant Pathology: Faculty Publications
BLACK et al. (1948) have published electron micrographs of bodies believed to represent the New York variety of potato yellow-dwarf virus (Aureogenus vastans (H) Black) (Holmes 1948). The photographs showed bodies in several different extracts of infected plants of Nicotiana rustica L., but not in corresponding preparations from healthy plants. Similar bodies were found in concentrates from plants infected with the New Jersey variety of the virus (var. agalliae Black). These bodies were larger than, and of a different character from, those of plant viruses hitherto examined in the electron microscope. The present study was undertaken to obtain evidence …

Application Of X-Ray Technique To The Detection Of Internal Insect Infestation Of Grain, Max Milner, Milford R. Lee, Robert Katz
Application Of X-Ray Technique To The Detection Of Internal Insect Infestation Of Grain, Max Milner, Milford R. Lee, Robert Katz
Robert Katz Publications
During the course of a comprehensive investigation of methods for the determination of internal insect infestation in commercial wheat, radiographic techniques have been developed at this station which provide satisfactory delineation of internal infestation. We have applied these techniques to the observation of the growth of such insects as granary weevil, Sitophilus granaries L., and rice weevil, Sitophilus oryza L., from the hatching of the egg within the kernel through larval and pupal growth to emergence as a mature insect. Although considerable detail is always lost in the reproduction of radiographs during engraving and printing, the accompanying figures (1, …

This is a textbook used at the Army Transportation School run by the Transportation Corps. In the 1950s, military schools related to one of the Army Technical Services were run by that service.
The modern US Army vision of the technical intelligence developed during World War II. Shortly before World War II, Army Technical Services had been instructed to set up intelligence sections in the offices of their chiefs. The technical services were bureaus which supplied weapons, equipment, and services to the Army, managed the careers of officers in a particular branch, trained specialists, and organized and trained special purpose …

This experiment requires apparatus consisting of two ring stands, two bunsen burners, safety matches, a sheet of hard asbestos board and a sheet of aluminum of approximately the same dimensions (6 in. long by 3½ in. wide by ⅛ in. thick). The ring stands are set side-by-side with the sheet of aluminum on one and the sheet of asbestos on the other. Two matches are placed on each sheet; one in the middle directly above the bunsen burner and one on the edge, two or three inches away. In what order will the matches catch fire after the burners are …
