Aircraft Quality Casting Standards, Robert Katz, Robert Bolin , Depositor

Robert Katz Publications

These standards are to be used in connection with the Handbook for Instructions for Aircraft Designers, 8^th Edition …

In the radiography of aircraft castings, markings appearing on the film may be attributed to either the condition of the castings examined, or to some details of the radiographic process entirely unrelated to the quality of the castings, These latter patterns must be recognized and related to the radiographic process so that sound castings will not be unnecessarily rejected. Radiographs must be carefully compared with the surface irregularities of the casting they represent before an attempt is made to …

Alfalfa Breeding, H. M. Tysdal, T. A. Kiesselbach, H. M. Westover

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Interest in the principles of alfalfa breeding has increased greatly with the growing "forage consciousness" of the country at large and the more specific interest developed through cooperation in the Alfalfa Improvement Conference. As is true of many other forage crops, information on the breeding behavior of alfalfa is meager. During the past few years, however, the genetics and principles of reproduction of this crop have come to be better understood and it is the purpose of this paper to bring together the available information pertaining to the improvement of alfalfa and to add certain suggestions with respect to future …

Teachers' Pay In Ancient Greece, Clarence A. Forbes

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

One who ventures upon an account of how the teachers of Greek antiquity fared in the matter of remuneration might do well to begin by entreating exemption from such a penalty a the luckless Phrynichus brought down upon himself for his tear-provoking tragedy of the mileton alusis. The Athenians fined Phrynichus a thousand drachmas, we are told, "because he had reminded them of their own troubles."

Generally speaking, intellectual labors in ancient Greece prior to the Hellenistic Age were undertaken for their own sake, with no thought of securing material rewards.2 The dramatists were spurred by competition, but not by …

Parabos Dodsoni Barbour And Schultz: A Correction, Erwin Hinckley Barbour, C. Bertrand Schultz

Department of Earth and Atmospheric Sciences: Faculty Publications

A Bos-like animal, Parabos dodsoni, was recently described by Barbour and Schultz (1941, "A New Fossil Bovid from Nebraska", Bull. Univ. Nebr. State Museum, Vol. II, No. 7, pp. 63-66, Figs. 24-27, December) as a new genus and species from the Pleistocene of Nebraska. Attention has been called to the writers by Dr. E. H. Colbert of the American Museum of Natural History that the name Parabos is preoccupied. Parabos was introduced as a generic name by C. Arambourg and J. Piveteau (1929, "Note preliminaire sur un Ruminant du Pliocene inferieur du Roussillon," C. R. Bull. Soc. Geol. de …

Competition Of Western Wheat Grass With Relict Vegetation Of Prairie, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Many profound changes in mid-continental grasslands have resulted from the recent extended drought. In the prairies of eastern Nebraska, Kansas and South Dakota, the earlier continuous stands of bluestem (Andropogon scoparius and A. furcatus) have often been greatly fragmented and now occur as relict patches a few square feet to many square rods in extent. Loss of approximately 95 per cent of little bluestem has left the prairie cover very open. Over large areas, except for weeds and a few surviving grasses and forbs, the soil was bared (Weaver, Stoddart and Noll, 1935; Weaver and Albertson, 1939). Grasses …

One Hundred Studies Of The Calcium, Phosphorus, Iron, And Nitrogen Metabolism And Requirement Of Young Women, Ruth M. Leverton, Alice G. Marsh

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The present study was undertaken to add appreciably to the data available on the metabolism of calcium, phosphorus, iron, copper, and nitrogen of young women on their customary self-chosen diets. It was planned to use the figures for the retentions or losses of these dietary essentials which occurred at various levels of intake to determine the requirement of the subjects and to evaluate the adequacy of present adult dietary standards for young women. The fact that the girls were living on self-chosen diets warrants emphasis. A large proportion of the subjects were doing light housekeeping and brought much of their …

An Analysis Of Pressure Gasoline And Pressure Kerosene Stoves, Arnold E. Baragar

Nebraska Agricultural Experiment Station: Historical Research Bulletins

During the past few years inquiries have been received regarding the cost of operation, efficiency, and performance of pressure gasoline and pressure kerosene stoves. Because of the method of operation and the use of gasoline as fuel, safety from fire and carbon monoxide has been frequently questioned. Not only is it necessary to have technical information about this type of appliance in order to compare it with other types but it is further important to know whether one type of burner is superior to another; whether one type of oven construction will give better results than another and in general …

The Effect Of Heat And Moisture On The Feeding Value Of Pilchard Meal, William B. Lanham, Hugo W. Nilson

United States Fish and Wildlife Service: Publications

The fish meals produced today have in general proved to be excellent sources of protein for the balancing of farm-animal rations. Some potential users, however, have refrained from feeding these products because of reports implying that fish meals, when fed to farm animals and poultry, have cause symptoms of toxicity.

It was considered possible that the meals suspected of producing toxic symptoms may have been subjected to conditions after manufacture that had altered them in an unsatisfactory manner. Therefore, the effect of excessive heat and humidity to simulate extremely unsatisfactory storage conditions was studied with pilchard meal.

Pilchard meal was …

Threonine Deficiency In Hydrolysates Of Zein Prepared By Autoclaving, Raymond Borchers, John R. Totter, Clarence P. Berg

Department of Biochemistry: Faculty Publications

In a previous paper (Borchers and Berg, 1942) we showed that

autoclaving zein with sulfuric acid longer than necessary for complete

hydrolysis causes destruction and racemization; either of

these might account for the failure of such a hydrolysate to

promote growth in young rats when substituted for a hvdrolysate,

prepared by refiuxing, in a diet which produced moderate growth.

It seemed to us that this deterioration in the dietary protein might

well be the result primarily of essential amino acid deficiencies

which could be detected and overcome by appropriate supplementation.

Because threonine is known to be present in zein in …

The Effect Of Conditions Of Hydrolysis And Of Prolonged Heating Upon The Optical Rotation Of Sulfuric Acid Hydrolysates Of Zein, Raymond Borchers, Clarence P. Berg

Department of Biochemistry: Faculty Publications

Some time ago we observed that a sulfuric acid hydrolysate of zein prepared in an autoclave at 165˚ did not support growth in young rats when it was supplemented with certain amino acids, even though the same amino acids, added to a hydrolysate prepared by refluxing, permitted moderate growth. Since the optical rotation of the autoclaved hydrolysate was lower than that of the refluxed, either destruction or racemization of essential constituents, or both, might have occurred. Loss of amino nitrogen and production of extra ammonia upon prolonged autoclaving of proteins with acids have been noted by Van Slyke (1912) …

The Relation Of Temperature To The Embryonic And Nymphal Development Of The Differential Grasshopper Melanoplus Differentialis Thomas, Myron H. Swenk, Charles H. Bratt

Temperature plays the major role in the regulation of the rate of embryonic development of the differential grasshopper (Melanoplus differentialis Thomas).

The Origin Of Daemonelix, Alvin Leonard Lugn

Department of Earth and Atmospheric Sciences: Faculty Publications

Attention is called to the controversy of some years ago over the origin of the "Devil's Corkscrews." The problem may have appeared unimportant then, but now a correct understanding of the paleoecology of Harrison time may hinge on the explanation of these strange "fossils." The characteristics of Daemonelix are briefly reviewed, they are compared to the lianas of the modern tropical jungle, and the postulated conditions of Harrison sedimentation are believed to supply an adequate explanation for the presence of fossil rodent remains in the Daemonelices. The possibility of a vegetal origin of these fossils is believed to be demonstrated.
