Bindweed Eradication In Nebraska, N. S. Hanson, F. D. Keim, D. L. Gross
Bindweed Eradication In Nebraska, N. S. Hanson, F. D. Keim, D. L. Gross
Nebraska Agricultural Experiment Station: Historical Circulars
Bindweed, which is easily recognized by its creeping, entwining habit of growth, is Nebraska's most destructive weed because of its effect on crop plants. Its total annual cost to the agricultural industry of the state is several million dollars, which ultimately affects all those citizens who depend directly or indirectly upon income from agriculture.

An Electrophoretic Determinatin Of The Properties Of Methacrol M.E. By The Use Of A Capillary Cross-Arm "U" Tube, Richard Reiland Bains
Bachelors’ Theses
this research was undertaken primarily to discover the use of a capillary cross-arm "U" tube in the determination of the electrophoretic and other electrical proper ties of a plastic emulsion.
The primary objective was to determine the isoelectric point of the emulsion and also the optimum pH or electro-endosmotic motion.
The secondary and distant objective was to note when, how, and it any coherent plating on the electrodes took place.

Bulletin No. 303 - Utilization Of Irrigable Land In The Reservation Area Of Uinta Basin, Utah, George T. Blanch, Clyde E. Stewart
UAES Bulletins
Several years ago the Utah Agricultural Experiment Station began a project entitled "Study of agricultural resources in Utah and their utilization." This project contemplates conducting detailed soils, irrigation water, range and economic studies in all areas of Utah. To date these studies have been made for a portion of the state including the Uinta Basin. However, in order that the information so obtained can be more effectively used for public and private programs of operation, there is a need to combine and correlate the basic data.
The primary objective of the study reported herewith is to bring together and analyze …

Bulletin No. 304 - Phosphate Reserves Of Utah, J. Stewart Williams, Alvin M. Hanson
UAES Bulletins
To supplement the work reported by the senior author in Bulletin 290 of the Utah Agricultural Experiment Station, the writers have visited the phosphate outcrops in Weber, Morgan and Salt Lake Counties, as well as those in the Park City District of Summit County and others west of Midway in Wasatch County. These areas were found to contain considerable phosphatic shale of 25 to 35 percent grade, but no rock of 40 percent grade, the minimum quality included in the estimates in Bulletin 290. However, the data recorded for the sections visited are valuable in showing the leanness of these …

Bulletin No. 302 - Nutritional Inadequacy Of Beet Molasses Rations For Swine, Russel A. Rasmussen, Harry H. Smith, Ralph W. Phillips, Ton J. Cunha
UAES Bulletins
The feeding of large amounts of beet molasses to young hogs causes a condition that is characterized by a wobbly gait, and that is frequently fatal. Hog raisers have apparently recognized this condition for a number of years, since a number of farmers have reported it in their animals. Some farmers have also reported breeding failures and abortions when beet molasses was fed to brood sows. Consequently, beet molasses has not been considered a good hog feed by Utah raisers.
Beet molasses is a relatively cheap source of carbohydrates and could be used advantageously in pork production if the cause …
The Scientist's Concept Of The Physical World, Willard Gardner
The Scientist's Concept Of The Physical World, Willard Gardner
Faculty Honor Lectures
To those who are aesthetic, there is perhaps nothing more inspiring than a beautiful sunset, with brilliant colors above the horizon and with banks of dark clouds above, set in the deep blue of the heavens, or the brilliant hues of the rainbow forming a halo about the majestic mountain with its coat of green, purple, brown, or gray. By these things are the emotions stirred.
The physicist too is emotional but he.is also at times realistic. He becomes sentimental but he also seeks to explain the behavior of nature. By means of devices and instruments his perceptual world is …

Bulletin No. 306 - Report Of The Agricultural Experiment Station Utah State Agricultural College, Logan, R. H. Walker
UAES Bulletins
The agricultural experiment stations have contributed in a very material way to the progress of agriculture in the United States not only by the development of better crops and livestock and production practices, but, through basic research on the many and varied problems of agriculture, they have furnished an understanding of those principles upon which progress must depend.
The permanent value of these research centers to the progress of agriculture is no better illustrated than in the present emergency. The ability of farmers to meet the tremendous additional contributions to defense in the way of increased food supplies is dependent …

Judging Quality In Dairy Products, P. A. Downs
Judging Quality In Dairy Products, P. A. Downs
Nebraska Agricultural Experiment Station: Historical Circulars
In the dairy industry increasing attention is being paid to the question of quality of products. The well established system of buying and selling butter and cheese on the basis of quality by score or grade is practiced in the principal markets of the world. The other dairy products, while not marketed by score, are receiving more and more attention in this respect. As more information becomes available and the judging better standardized, other dairy products will doubtless be sold by grade.

The Effect Of Irradiation Upon The Fecundity Of Drosophila Melanogaster, Arnt M. Erickson
The Effect Of Irradiation Upon The Fecundity Of Drosophila Melanogaster, Arnt M. Erickson
Bachelors’ Theses
Many animals and plants are being subjected to irradiation of various types with the object of discovering the effect upon the development of the organism. This type of experimentation is still in its initial stages. The considerations which led to the choice of the fruit fly, Drosophila melanogaster, for the investigation were briefly the following: (a) its small size which insures that all parts of the ~ animal will receive approximately equal exposures to the radiations; (b} the fact that it passes through a pupal stage during which it may be conveniently manipulated in such irradiation work; (c) the …

Bulletin No. 295 - Comparison Of Two Methods Of Determining Wool Density, Milton A. Madsen, Ralph W. Phillips, John V. Christensen, Roy L. Henrie
UAES Bulletins
Density of the fleece is one of the primary factors determining the wool-producing capacity of the sheep. Sheepmen have attempted to evaluate density by handling the fleece. This method is not sufficiently refined for use in experimental work, and may be subject to errors and misinterpretations. For example, if two fleeces are alike in density and diameter of fibers, yet differ in length, the longer fleece will feel less dense. If, on this basis, the sheep with the fleece that appeared most dense were selected for breeding, selection would be away from the longer fleece. Any method that can be …
Wildlife Of The Atlantic Coast Salt Marshes, W. L. Mcatee
Wildlife Of The Atlantic Coast Salt Marshes, W. L. Mcatee
United States Fish and Wildlife Service: Publications
Salt marshes of the Atlantic coast have been formed under the opposed tendencies of sinking of the land and of its upbuilding by silt and sand. The plants that form the marshes occupy zones largely determined by the degree of inundation by tides. Eelgrass entirely submerged, smooth cordgrass regularly washed by the tide, and marsh hay covered only by exceptionally high water are characteristic plants. Each zone is the home or feeding area of certain kinds of wildlife. The appearance, distribution, and habits of the more common species are described, and general wildlife conservation is urged. This circular, which is …

The Pipy Concretions Of The Arikaree, C. Bertrand Schultz
The Pipy Concretions Of The Arikaree, C. Bertrand Schultz
Bulletin of the University of Nebraska State Museum (1924–2023)
The pipy concretions of the Arikaree (lower Miocene) of Nebraska and adjacent states were first described by Nelson Horatio Darton (1899, p. 743) as "characteristic layers of hard, fine-grained, dark-gray concretions, often consisting of aggregations of long, irregular, cylindrical masses" (see Figures 30, 32, 34, and 35). The individual pipes vary in diameter from a few inches to several feet, and in length from a few inches to a hundred yards or more. Tests demonstrate that pipy concretions are composed of sand cemented by calcium carbonate. When dipped in acid the cement is dissolved and the concretion is reduced to …

Bulletin No. 294 - Research Aids Utah Agriculture: Biennial Report Utah Agriculture Experiment Station 1938 - 1940, R. H. Walker
UAES Bulletins
The foundation of progress in agriculture as in any other industry is research. Research has resulted in knowledge now daily applied in soil treatment, in irrigation practices, in dealing with insect pests, in breeding new varieties of plants, in animal improvement, in better farm practices, and in better land-use planning. Research undertaken by the Utah Agricultural Experiment Station has been outlined to solve specific problems facing Utah agriculture, among them the problems of irrigation, dry farming, range management and animal production. The prosperity of the state is dependent upon the success of these agricultural enterprises. Agricultural research should not, therefore, …

Utah State Agricultural College Graduates Now Living In Other States, Robert Dawson Simpson
Utah State Agricultural College Graduates Now Living In Other States, Robert Dawson Simpson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This is a study of graduates of the Utah State Agricultural College who have left Utah and are now residing elsewhere. Inquiries by faculty members and interested alumni, as well as the writer's own interest in the subject of migration, prompted the organization of this study.
The immediate reason for the inquiry was an enlarging interest on the campus concerning the present whereabouts of graduates who have left the state. When present residence was ascertained, other questions arose. What kind of employment had migrating graduates secured? What major interests were had? What important voluntary public services are graduates rendering to …
