How To Reseed Utah Range Lands, A. Perry Plummer, Richard M. Hurd, C. Kenneth Pearse
How To Reseed Utah Range Lands, A. Perry Plummer, Richard M. Hurd, C. Kenneth Pearse
Aspen Bibliography
Additional low cost forage is urgently needed by Utah's range livestock industry. Seeding of depleted tracts in accordance with recently developed methods and principles will help supply this forage and is entirely feasible. Where the value of the increased forage will repay the cost of planting, careful reseeding of selected sites is fully justified.
The important part that reseeding can play in restoring ranges to their former capacity has been demonstrated. Although satisfactory results can be obtained on many sites during average or better years, much more study is needed to insure consistent success in abnormal years and to extend …
The Urogenital System Of The Male And Female English Sparrow, Passer Domesticus, Peter Paul Wisniewski
The Urogenital System Of The Male And Female English Sparrow, Passer Domesticus, Peter Paul Wisniewski
Bachelors’ Theses
The testes is a pair of oval organs posterior to the lungs and anterior to the kidneys. Each testes is attached by a mesentery to the anterior end of the kidney. An adrenal gland is located at the anterior portion of each testes. The vasa deferentia are slender convoluted tubules. Each arises from the median edge of the testes passes cauded along the ventral surface of the kidney, paralleling the ureter and enlarging slightly at the distal end to form a small seminal vesicle, which enters the urogenital region of the cloaca by a papilla. The male urodaeum is smaller …

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 …

Plant Diseases Common, Destructive, Preventable In South Dakota (Revised), W.F. Buckhholtz
Agricultural Experiment Station Plant Pathology Pamphlets (1942-1962)
Abundant agricultural production is a victory goal and in South Dakota is based on an abundance of feed, forage and cash field crops and an adequate home vegetable and fruit supply. On the other hand, soil conservation and the maintenance of South Dakota’s agricultural productivity depends on a practice of moderate rather than wholesale over-cropping of cultivated land. Shortages of labor and machinery place a definite limit on the amount of really good farming that can be done it South Dakota for the duration of the war. One of the ways to insure maximum crop production from a minimum of …
Food From The Sea: Fish And Shellfish Of New England, Rachel L. Carson
Food From The Sea: Fish And Shellfish Of New England, Rachel L. Carson
United States Fish and Wildlife Service: Publications
Millions of Americans are developing new wartime food habits, trying foods they once neglected, turning to alternates for long familiar products. For everyone of the ten fish or shellfish that make up mere than four-fifths of New England's catch there are seven species little known or utilized, many of which could provide tasty and nutritious foods. Turning to these under-utilized species will conserve food resources by lifting the burden of over-exploitation from such fishes as cod and haddock and will augment dwindling supplies of protein foods. Exploring the seafood markets for unfamiliar species rewards the housewife and her family with …

Student Agricultural Work Experiences In San Joaquin County, With Particular Reference To The Work Experiences Of Students Of Stockton And Lodi Public Schools In The Summer Of 1942, Frank L. Nash Jr.
University of the Pacific Theses and Dissertations
As early as February, 1942, fears of an agricultural labor shortage began to be expressed in California. The Pacific Southwest Area Committee of the Young Men’s Christian Association asserts in a statement of policy on Emergency Harvest Camps, “The California State Chamber of Commerce’s Central Coast Council’s Agricultural Committee points out that ‘the removal of enemy aliens from coastal areas, the absorption of migrant workers into defense industries, and increased government quotas for the production of many crops has created a serious agricultural problem.’ (News release, February 28, 1942).”
In San Joaquin County 5,000 Japanese were evacuated. Most of these …

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 …
A Study Of Fluctuations In Coyote Numbers And Possible Causes, Sherwin B. Griswold
A Study Of Fluctuations In Coyote Numbers And Possible Causes, Sherwin B. Griswold
Master's Theses or Doctor of Nursing Practice
This paper reports the findings of a study of coyote numbers, with particular reference to fluctuations, their periodicity, if any, and their possible causes. In order to answer these questions studies of bounty payments were made in four centrally located counties of Kansas. The counties selected for this study were Ellis, Russell, Edwards, and Harvey. The location of these counties is shown in figure I on page 5. A record of these bounty payments was secured by checking through the records in the office of the county clerk of these counties for all years in which records were on file.

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

Bulletin No. 301 - Economic Analysis Of The Weber Central Dairy Association, Walter U. Fuhriman, Harold H. Culter, W. Preston Thomas
UAES Bulletins
At the request of the dairymen in the Ogden milk shed the Department of Agricultural Economics, Utah Agricultural Experiment Station, made an analysis of 162 dairy farms in the Ogden area for the years 1937, 1938 and 1939. The study covered the entire farm business and a detailed analysis of the dairy enterprise.
Since production of dairy products is closely associated with, and is affected by, the marketing institutions which provide outlets for these products, an analysis of marketing phases was made through a study of Weber Central Dairy Association , one of the larger dairies of the area . …
A Study Of The Ring-Necked Pheasant (Phasianus Colchicus Torquatus Gmelin) In Northern Utah, William T. Mckean
A Study Of The Ring-Necked Pheasant (Phasianus Colchicus Torquatus Gmelin) In Northern Utah, William T. Mckean
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Purpose of Study. The ring-necked pheasant (Phasianus colchicus torquatus Gmelin) is well enough known to need no introduction. It is at present undoubtedly the most abundant and most important gallinaceous game bird in northern Utah. Its abundance and its occurrence in agricultural areas has stimulated much general interest. Yet, aside from two food habits studies, both conducted in Utah County, no intensive research has been made into its ecological relationships or its general life history in Utah.
In order to formulate sound management plans for the pheasant in Utah, the Utah Cooperative Wildlife Research Unit has felt the need …

Inbreeding And Selectional Studies Of Drosophila Melanogaster, Marian Cecilia Dellers
Inbreeding And Selectional Studies Of Drosophila Melanogaster, Marian Cecilia Dellers
Bachelors’ Theses
The eyeless gene of Drosophila, which causes in general a reduction of the size of the eye in the adult fly, does not seem to produce a constant effect. Thus among the offspring of one pair of flies many phenotypes will be found, flies with reduced eyes of various sizes and flies with one or both eyes completely missing. The purpose of this series of experiments was to investigate the genetical and environmental factors involved in the modification of the results produced by the eyeless gene and to determine their relative importance, especially through selective breeding in the direction of …
The Effect Of Sulfanilamide On The Spleen, Kidney, And Erythrocytes Of The Albino Rat, Paul M. Bergen
The Effect Of Sulfanilamide On The Spleen, Kidney, And Erythrocytes Of The Albino Rat, Paul M. Bergen
Bachelors’ Theses
Sulfanilamide today is recognized somewhat as a magical drug since it is being used in the cure of so many different diseases. Therefore it was my desire to experiment with it. The problem which the author has endeavored to solve has been, as the title implies, just what effect the drug has upon the blood, the cells of the spleen and the kidney. It has been my aim to verify or refute the findings of experimenters who have delved in the field previous to my experimentation, l and to attempt to give some explanation for the findings.
Colorless Fuchsin: A Staining Technique For The Salivary Gland Chromosomes Of Drosophila Melanogaster, Gordon I. Koehler
Colorless Fuchsin: A Staining Technique For The Salivary Gland Chromosomes Of Drosophila Melanogaster, Gordon I. Koehler
Bachelors’ Theses
The chromosome theory of heredity opened a large field for both cytologists and geneticists. They looked to the day when someone would find an organism in which the chromosomes were so large that it would be possible to see Qualitative differences along their length corresponding to the different genes which they knew must be present at these points. Before 1932, methods and materials to show these chromosomes to any appreciable extent had, however, not yet been devised. Competent observers using the finest of optical equipment, and the most refined techniques of staining could see little at the time of nuclear …
Competition Of Western Wheat Grass With Relict Vegetation Of Prairie, J. E. Weaver
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 …

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 …

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 …

Threonine Deficiency In Hydrolysates Of Zein Prepared By Autoclaving, Raymond Borchers, John R. Totter, Clarence P. Berg
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
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 Incidence Of Trichinella Spiralis In The Diaphragms Of Swine From The Louisville Abattoirs., Stuart Lyle Adams
Electronic Theses and Dissertations
Trichinosis is a disease caused by the parasitic nematode Trichinella spiralis. When meat containing encysted larvae is consumed the cysts are dissolved by the action of the gastric juice in the stomach and the larvae migrate to the intestine where they mature, copulate and give birth to living young within a week of the original infection. The larvae enter the lymph spaces and are carried to the thoracic duct from which they reach the venous circulation and thence the arterial circulation by way of the heart and the pulmonary capillaries. From the arterial blood the larvae enter most of the …
