Glacial Geology Of Wabash County, Indiana, William J. Wayne, William D. Thornbury
Glacial Geology Of Wabash County, Indiana, William J. Wayne, William D. Thornbury
Department of Earth and Atmospheric Sciences: Faculty Publications
Most of the topographic features of Wabash County are of glacial origin or are glacial deposits eroded by postglacial streams. Shales, limestones, and dolomites, all Silurian, are exposed only along some of the deeper valleys. Four major rivers and six smaller streams in Wabash County flow in glacial sluiceways. Only the Eel and Wabash sluiceways carried large quantities of melt-water. The Eel River valley train occupies an interlobate position, and the Wabash Valley bears evidence of its roles as a sluiceway and as an outlet for glacial Lake Maumee in late Cary time. Three topographic areas comprise the upland part …

The Upland Game And Migratory Waterfowl Harvest, Russell W. Stuart
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
This report presents the results of data gathered by questionnaire from a random group of North Dakota license holders during the 1951 season and a report from 130 non-resident license holders who voluntarily filled out and returned a card attached to the non-resident license. The two sets of data will be treated separately in the report.
United States Patent: Antenna Guy Fitting, Robert Katz
United States Patent: Antenna Guy Fitting, Robert Katz
Robert Katz Publications
The invention to be hereinafter described relates to coupling devices for the attaching of fixed wire antenna to aircraft.
Heretofore, it has been the general practice to make connections between the fixed wire antenna and aircraft by wrapping the antenna wire about a thimble or like device, as in making a splice.
This practice resulted in a number of sharp points and rough surfaces whose susceptibility to corona discharge is well known. This corona discharge resulted in bad weather extremely difficult or dangerous due to interruption of radio navigation and communication services.
The present invention is designed to overcome the …
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, …

All tractors tested at the Nebraska Tractor Test Laboratory were certified by their manufacturers as being stock model machines, conforming to specifications filed with the application for test. No special or high-test fuels were used except as recommended by the manufacturer as necessary. All results within the official tractor test report were actually attained in tests and are without correction or allowances for friction, temperature, altitude, etc. The results were initially accomplished with the tractor in charge of skilled operators employed by the University. Unless otherwise noted, each tractor was apparently in good condition at the end of the testing …
A Simple Experiment On Heat, Robert Katz
A Simple Experiment On Heat, Robert Katz
Robert Katz Publications
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 …

Effect Of Stubble Mulching On Number And Activity Of Earthworms, S. P. Teotia, F. L. Duley, T. M. Mccalla
Effect Of Stubble Mulching On Number And Activity Of Earthworms, S. P. Teotia, F. L. Duley, T. M. Mccalla
Nebraska Agricultural Experiment Station: Historical Research Bulletins
A survey of earthworm population under different cropping systems was made under stubble mulch farming and where the residue was plowed under. The influence of earthworms on some of the important physical and biological properties of the soil was studied. Their role in the decomposition of crop residues was also determined.

EXPLANATION OF TEST REPORT: John Deere MC 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.

The Pleistocene Geology Of The Middle ·Portion Of The Elkhorn River Valley, W. D. Frankforter
The Pleistocene Geology Of The Middle ·Portion Of The Elkhorn River Valley, W. D. Frankforter
University Studies (University of Nebraska): Papers
The present report is a physiographic and paleontologic approach to the Pleistocene history of a portion of the Elkhorn River Valley in parts of Dodge, Cuming and Stanton counties in northeastern Nebraska. The area is important for correlation of deposits between the glacial and periglacial regions. Some of the critical stratigraphic units used for correlation in the Pleistocene of these regions are present in close association with the tills and contain fossils which make possible reliable statements on contemporaneity of deposits. The subsequent geologic history and present physiographic expression of this area have been greatly controlled and influenced by the …
