An Annotated List Of The Orthoptera Of Nebraska Part Ii The Tettigidae And Acrididae, Harold A. Hauke
Bulletin of the University of Nebraska State Museum
This is the second of a series of papers on the Orthoptera of Nebraska. It is a continuation of the revision of an unpublished thesis on this subject by the author in 1934.
Commercial Fertilizers For Winter Wheat In Relation To The Properties Of Nebraska Soils, R. A. Olson, H. F. Rhoades
Commercial Fertilizers For Winter Wheat In Relation To The Properties Of Nebraska Soils, R. A. Olson, H. F. Rhoades
Nebraska Agricultural Experiment Station: Historical Research Bulletins
It is the purpose of this bulletin to report the investigations that have been made correlating soil properties and fertilization practices with yields of winter wheat. Since the success or failure of fertilization practices is so dependent on specific soil conditions, an attempt has been made here to further characterize the major soils of the different sections of the state which are devoted to wheat production and to analyze fertilizer practices and results in relation to the soil properties determined. The data are summarized for the four sections of the state designated as southeastern, east-south-central, west-south-central and western Nebraska. These …

Summary of your 1953 Winter Records
As we have mentioned before, an important item from the winter counts is the ratio of cock pheasants to hen pheasants after the season has ended. Your winter records showed 88 cocks per 100 hens for the state as a whole. In extreme southeastern Nebraska (where pheasants are scarce), and for central and western Nebraska, you recorded more cocks than hens. For most of the eastern third of the state (where most of the pheasant hunting is done) you recorded two cocks for every three hens. This reflects the removal of more cocks by …

A Theoretical Formulation Of The Hammett Equation, Gordon A. Gallup, W.R. Gilkerson, M.M. Jones
Gordon Gallup Publications
A relation, which reduces to the form of Hammett's equation, has been derived. Reactions which can be assumed to be of the form ion-dipole or dipole-dipole have been considered. The logarithms of the ratios of rate constants were calculated and compared with experimental values in the form of Hammett's equation constants.

Pleistocene Evolution Of The Ohio And Wabash Valleys, William J. Wayne
Pleistocene Evolution Of The Ohio And Wabash Valleys, William J. Wayne
Department of Earth and Atmospheric Sciences: Faculty Publications
Studies of drift thickness and character currently in progress in Indiana indicate changes in drainage that have occurred in Indiana and some adjoining states since the beginning of the Pleistocene epoch. After late Tertiary (Lexington) peneplanation the master-drainage line, the Mahomet-Teays Valley system, became entrenched about 200 feet below its former level before it was ponded by Nebraskan ice and diverted into a new course. During the Parker cycle, which was interrupted by glaciation, the present physiographic features of southern Indiana and their now buried extensions to the north became recognizable. Static rejuvenation then was a major factor in erosion …

Nebraska Tractor Tests
This report and any related files are made available to the online through the Lester F. Larsen Tractor Test and Power Museum as resources allow. 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 …

EXPLANATION OF TEST REPORT: John Deere 50 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.

Internal Fissuring Of Wheat Due To Weathering, Max Milner, J. A. Shellenberger, M. R. Lee, Robert Katz
Internal Fissuring Of Wheat Due To Weathering, Max Milner, J. A. Shellenberger, M. R. Lee, Robert Katz
Robert Katz Publications
Radiographic technique developed at this Station for the determination of internal or hidden insect infestation in stored grain has proved to be useful for the detection of other physical anomalies in grains. Practical applications of this sort include the detection of cracked or broken kernels in rough rice (paddy) prior to milling as well as the extent of internal fracturing of certain grains such as maize due to uneven stresses arising from severe drying conditions. This communication deals with a condition of internal fissuring occurring in wheat due to weathering of the ripened grain in the field.

Hydrogen Bond Energies In Carboxylic Acids, M.M. Jones, W.R. Gilkerson, Gordon A. Gallup
Gordon Gallup Publications
A question of interest to the study of the chemisorption of carbon monoxide on iron is whether the carbon is desorbed with the same oxygen to which it was bonded prior to the adsorption. A mixture of C13O and CO18 in the desorbed gas in amounts greater than expected from normal abundance ratios shows that an intermolecular oxygen exchange occurs.

Chemical Reactions Near Equilibrium, W.R. Gilkerson, M.M. Jones, Gordon A. Gallup
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.

Although the spectrographic analysis accompanying several enriched samarium isotopes from Oak Ridge contained <0.6 percent europium, some of the more intense internal conversion lines attributed to the disintegration of europium have been found photographically with neutron-activated samarium isotopes in a 180° focusing β-ray spectrograph.
