Radiography Applied To Grain And Seeds, Max Milner, Milford R. Lee, Robert Katz

Robert Katz Publications

A radiographic method for the detection of internal insect infestation in grain by means of low energy radiation from a cobalt-target beryllium-window X-ray tube is described. The utility of the technic for inspection of wheat, corn, rice, and beans is illustrated with cuts made from original radiographs.

A Report On Drosophila Collections In Nebraska, David D. Williams, Dwight D. Miller

Bulletin of the University of Nebraska State Museum

Until rather recently little has been known of the Drosophila species of Nebraska. Sturtevant (1921) lists Nebraska as one of seven states from which no Drosophila had been reported. Patterson and Wagner (1943) show that collections of Drosophila pseudoobscura had been made in the vicinities of Scottsbluff and Kearney, but no other Drosophila species are reported from Nebraska in their publication.

Nebraska Tractor Tests

EXPLANATION OF TEST REPORT: John Deere 60

TEST A: The manufacturer's representative operates the tractor for a minimum of 12 hours using light to heavy drawbar loads in each gear.

This serves as a period for limber up, general observation and adjustments. Adjustments that are permissible include valve tappet clearance, breaker ,point gap, spark plug gaps, clutch and others of a similar nature. No new parts or accessories can be installed without having mention made of it in the report. No data' are recorded during this preliminary run except the time that the engine is operated.

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 …

Waterfowl Breeding Ground Survey, 1952 In Nebraska, Harvey W. Miller

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

The Nebraska Breeding Ground Survey has been conducted for the fifth consecutive year. This survey is aimed at providing indicators to the waterfowl population through measuring the seasonal and year b,y year trends in breeding numbers and production success. The survey recognizes the sandhill region as the most important waterfowl-producing area of Nebraska and therefore, studies have been largely concentrated there.

1952- Pheasant Brood Observations (For 1952), Levi L. Mohler

Pheasant Brood Observations

Ten broods have been reported to date by Grasmick, Burney, Bunney, Bowers, Owen, Schultz, Jensen and Cassell. Twelve other men have reported their first two broods.

Insect Types In The Collections Of The University Of Nebraska State Museum, Martin H. Muma

Bulletin of the University of Nebraska State Museum

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.

The Red Cloud Sand And Gravel, A New Pleistocene Formation In Nebraska, C. Bertrand Schultz, Eugene C. Reed, A. L. Lugn

Conservation and Survey Division

Recent studies of the stratigraphy and paleontology of the Pleistocene of Nebraska have resulted in additional data that require further clarification and partial revision of the Grand Island sand and gravel formation (1,2) in order that there may be no condusion as the results of varying usage of the term.

Department of Earth and Atmospheric Sciences: Faculty Publications

Recent studies of the stratigraphy and paleontology of the Pleistocene of Nebraska have resulted in additional data that require further clarification and partial revision of the Grand Island sand and gravel formation (1,2) in order that there may be no confusion as the result of varying usage of the term.

The Nebraska Geological Survey, the University of Nebraska State Museum, and the Department of Geology at the University of Nebraska have approved the foregoing restriction of the term Grand Island and the adoption of the new name Red Cloud sand and gravel, and these names will be used in future …

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.

A Graphic Résumé Of The Pleistocene Of Nebraska (With Notes On The Fossil Mammalian Remains), C. Bertrand Schultz, Gilbert C. Lueninghoener, W. D. Frankforter

Bulletin of the University of Nebraska State Museum

I T SEEMS desirable at this time to present a graphic resume of the Nebraska Pleistocene, together with a summary of the stratigraphic sequences of the fossil vertebrates. This report is based on data taken from various publications' in addition to information gathered by the present writers during the past fifteen or more field seasons. Intensive work has been done in the past five years in connection with recovery of paleontological material in the areas where government dams are under construction (Schultz, Lueninghoener, and Frankforter, 1948; Schultz and Frankforter, 1948; Holder and Wike, 1949). The information in the present paper …

Progress Report: Chemical Quality Of The Surface Waters In The Loup River Basin, Nebraska, John G. Connor

United States Geological Survey: Publications

The Loup River and its tributaries transport moderate amounts of siliceous minerals from the sand hills region of north-central Nebraska to the Platte River near Columbus, Nebr. Predominant chemical characteristics of these waters are a high percentage of silica, moderate hardness, and a low percentage of sodium. The composition of the Loup River water is influenced by the geologic formations through which ground water, a major contributor to the flows of the Loup River branches, has percolated. Investigation of water quality at or near proposed dam sites in the Loup River basin indicates that if soil and drainage conditions are …

Established in 1998, this museum is located on the University of Nebraska-Lincoln East Campus. It is and appropriately housed within the walls of the historic 1920 Nebraska Tractor Test Laboratory, where the first tractor test was started on March 31st, 1920. Because the pioneer tests became worldwide standards, this location was designated as a Historic Landmark of Agricultural Engineering by the American Society of Agricultural Engineers in 1980, shortly after testing was moved to a …
