A Study Of The Craft Activities In Summer Recreation Programs In Relationship To Weber County, Utah, Leonard W. Glismann May 1952

A Study Of The Craft Activities In Summer Recreation Programs In Relationship To Weber County, Utah, Leonard W. Glismann

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A quick observation in this modern world makes one realize the great problem of leisure time that is upon us. Man is working fewer hours and retirements are at a younger age. Now man finds himself poorly prepared to cope with the situation. In our schools today millions of dollars are spent teaching art, crafts, dramatics, music, and physical education in an attempt to train for leisure, yet we spend a comparatively little amount of money for continuing these activities in out-of-school hours.


The Effects Of Salt Content And Temperature On Eye Formation In Swiss Cheese, Kenneth B. Creer May 1952

The Effects Of Salt Content And Temperature On Eye Formation In Swiss Cheese, Kenneth B. Creer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The size, shape, and handling of the large swiss cheese wheels have given rise to problems of labor, marketing, and waste in cutting. At the present time, there is a trend to produce a smaller swiss cheese which will enable the manufacturer and marketing agencies to overcome the difficulties in handling the large wheels.


The Effect Of Feeding Sucrose To Beef And Swine On The Percentage Of Carbohydrate, Ph, Color, Texture, And Flavor Of Muscle And Liver, Margaret B. Merkley May 1952

The Effect Of Feeding Sucrose To Beef And Swine On The Percentage Of Carbohydrate, Ph, Color, Texture, And Flavor Of Muscle And Liver, Margaret B. Merkley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Carbohydrates have long been a part of animal feeding rations. Grains are included in all animal feeding formulas. The by-products of sugar beets have been used for many years in livestock feeding (Kutish 1950b). The use of molasses in commercial feed mixes in 1899 made possible its extended use in animal feeding practices (Hall 1950).

Protein feeds for cattle are relatively high in price and not available in adequate supply. With these facts in mind Culbertson of Iowa State College set up experiments in 1950 to find out whether part or all of the protein supplement could be replaced with …

Ascorbic Acid And Glucose: Their Relation To Rheumatic Fever In Utah, And Their Relation To Incidence Of Dental Caries In Idaho, Patricia Wood

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Diseases which in the sixteenth century were found to be related to a deficiency of some substance in the natural foods consumed in the diet were later known as deficiency diseases. As early as 1881, Lunin found that rats could not live on a purified diet of carbohydrate, fat, protein and minerals, but could exist on a diet supplemented with certain natural foods. These findings were found to be in agreement with records of early descriptions of deficiency diseases. Scurvy was recognized very early in voyages made across oceans where ships had no means of being re-provisioned. Progress was very …

Control Of Pheasant Eye As It Affects Yield And Other Related Factors In Winter Wheat, Ray J. Downs May 1952

Control Of Pheasant Eye As It Affects Yield And Other Related Factors In Winter Wheat, Ray J. Downs

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Pheasant eye (Adonis annua L.), a native of Europe, is commonly cultivated as an ornamental, but occasionally escapes into fields and waste places. It is prevalent in certain areas in the United States, especially southward, on heavy soils that are inadequately drained (20). This plant is one of a number of early maturing winter annual weeds that infests dryland wheat in northern Utah, and it has become a problem in certain lowland areas.

This weed cannot be controlled by usual cultural practices because it makes most of its growth during the time of the year when the soil is …


The Consumptive Use Of Water In Milford Valley, Utah, Terrel R. Tovey May 1952

The Consumptive Use Of Water In Milford Valley, Utah, Terrel R. Tovey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Consumptive use, as used in this thesis, is defined as the sum of the volumes of water used by the vegetative growth of a given area in transpiration and building of plant tissue and that evaporated from adjacent soil, snow, or intercepted precipitation of the area in any specified time, divided by the given area. If the unit of time is small, the consumptive use is expressed in acre-inches per acre or depth in inches, whereas, if the unit of time is large, such as growing season or a 12-month period, the consumptive use is expressed as acre-feet per acre …


An Investigation Concerning The Incidence And Pathogenicity Of Pentatrichomonas Gallinarum And Its Relationship To Histomonas Meleagridis In Turkeys In Utah, Ross S. Hadfield May 1952

An Investigation Concerning The Incidence And Pathogenicity Of Pentatrichomonas Gallinarum And Its Relationship To Histomonas Meleagridis In Turkeys In Utah, Ross S. Hadfield

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Turkey raising has become big business. During the period 1942 to 1946, the average annual return in Utah amounted to about nine and one-half million dollars (4). This amount would have been increased considerably if the death loss among poults had been lower. As an example, using the percentage of mortality given by Miner (9, p. 5), it is estimated that the death-loss of turkeys in 1944 resulted in a loss of gross income by the farmers of Utah of more than four million dollars provided that the price the farmer received had remained the same.

Among the prevalent causes …


The Iron Content Of Some Plants As Influenced By Conditions Associated With Lime-Induced Chlorosis, Robert E. Warnock May 1952

The Iron Content Of Some Plants As Influenced By Conditions Associated With Lime-Induced Chlorosis, Robert E. Warnock

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Throughout much of western United States the soils contain considerable calcium carbonate. This lime is either distributed throughout the soils profile or it occurs in a zone of accumulation at varying depths. On many of these soils certain plants exhibit a chlorosis in varying intensity. This chlorotic condition is not stable as it varies from year to year and even day to day with changing conditions of climate and soil. this chlorosis has been reported from the wine and fruit regions of Europe, from the pineapple and sugar cane areas of Puerto Rico and Florida, from the sorghum and bean …


Zinc Deficiency In Soils As Affected By Soluble Phosphate, Glen E. Leggett May 1952

Zinc Deficiency In Soils As Affected By Soluble Phosphate, Glen E. Leggett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Zinc deficiency in Utah is found in about 7 per cent of the orchards. The severity varies from minor cases to sever instances in which many of the trees have died. The areas where zinc deficiency is found are becoming more extensive as land cultivation continues.

The treatment of the disorder is expensive and must be repeated often, for it cannot be overcome by the addition of zinc to the soils. The soils in Utah seem to have ample zinc, but in areas where zinc deficiency occurs it apparently is in a form which is not available for plant growth. …

A Comparative Study Of Raw, Pasteurized, And Hydrogen Peroxide Treated Milk In The Production Of Swiss Cheese, John Darold Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

At the present time the Swiss cheese making process is a prolonged one requiring several operations and considerable space. The cheese is made in wheels weighing approximately 200 pounds and is covered by a thick rind. There is considerable waste in cutting these large wheels to fit the present merchandising methods.


A Management Study Of The Idaho-Utah Interstate Deer Herd With Special Reference To The Sublett, Black Pine, And East Raft River Mountain Unit, Kenneth L. Diem May 1952

A Management Study Of The Idaho-Utah Interstate Deer Herd With Special Reference To The Sublett, Black Pine, And East Raft River Mountain Unit, Kenneth L. Diem

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Extensive deer migrations have been observed for many, years in western mountain regions. More recently several complex interstate migrations have become the objects of careful study and the subjects of special wildlife movement programs. The interstate deer migrations between the Sublett-Black Pine, Idaho, areas and the East Raft River Mountain, Utah, area are not exceptional. These migrations are now of such a magnitude that they are creating management problems of increasing importance to the 2 states involved.

Electric Chick Brooding Studies, F. D. Yung, F. E. Mussehl Apr 1952

Electric Chick Brooding Studies, F. D. Yung, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Circulars

Perhaps one of the most valuable lessons to be learned from a study of chick brooding is that good results can often be obtained in more ways than one. In carrying on work with electric brooders at the Nebraska Agricultural Experiment Station, special attention has been given to such factors as insulation and to other details of design which effect economy of operation and ease of construction. Low cost rather than "cheapness" has been the ideal. The work has been cooperative between the Agricultural Engineering Department and the Poultry Husbandry Department of the University of Nebraska.

Stratigraphy Of The Woodbine Formation In The Arlington Area, Tarrant County, Texas, Charles Fremont Dodge Apr 1952

Stratigraphy Of The Woodbine Formation In The Arlington Area, Tarrant County, Texas, Charles Fremont Dodge

Field and Laboratory

The Arlington area includes 70 square miles in eastern Tarrant County, Texas. It is bounded on the west by the meridian 97° 10' 00" W, on the east by the line between Tarrant and Dallas Counties, and on the north and south by the parallels 32° 47' 30" and 32" 40' 00" N. The area is drained by the Trinity River and its tributaries, which together form a dendritic pattern. Erosion by these streams has produced a submaturely to maturely dissected terrain with maximum local relief of 200 feet. The degree of dissection varies from north to south. In the …


The Wheeler Site: A 3,500 Year-Old Culture In Dallas County, Texas, Wilson W. Crook Jr. Apr 1952

The Wheeler Site: A 3,500 Year-Old Culture In Dallas County, Texas, Wilson W. Crook Jr.

Field and Laboratory

Discovery and investigation of the Wheeler site near Carrollton, Dallas County, Texas, has led to the tentative identification of a 3,500-year-old, "Little Pluvial" age, non-pottery culture in north Texas; it seemingly is a phase of a larger complex which at one time occupied the upper reaches of the Trinity River drainage and the middle area of the Brazos River, and may possibly demonstrate relationships with the "Desert Cultures" of California-Lower California to the west, vestiges of a late contact with remnants of the old Plainview-type culture, and with the eastern Archaic from the Mississippi Valley.


The Skeleton Of The Arm Of Necturus, Joseph P. Harris Jr. Apr 1952

The Skeleton Of The Arm Of Necturus, Joseph P. Harris Jr.

Field and Laboratory

Wilder's (1903) description of the skeleton of Necturus is the only one, to date, that is anywhere near complete. Other authors (Mivart, 1869; Ribbing, 1906-07; Howell, 1936; Straus, 1942) have noted portions of the arm-skeleton incidentally to describing various muscles. Chen (1935) described the embryonic development of the pectoral limb. All of these notes generally agree, except in a few details. Francis (1934) described the skeleton of Salamandra. For reasons to appear later, I adopt the terminology of Francis for the skeletal elements of the arm of Necturus.

Helminths From The Round-Tailed Muskrat, Neofiber Alleni Nigrescens Howell, With Descriptions Of Two New Species, Robert L. Rausch Apr 1952

Helminths From The Round-Tailed Muskrat, Neofiber Alleni Nigrescens Howell, With Descriptions Of Two New Species, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Two specimens of round-tailed muskrat, Neofiber alleni nigrescens Howell, were examined for helminth parasites. Four species, a trematode and three cestodes, were collected. Two of these, Quinqueserialis floridensis and Paranoplocephala neofibrinus, are described as new. Cittotaenia praecoquis Stiles, 1895, is recorded from this host, and larval cestodes are tentatively identified as Taenia lyncis Skinker, 1935.

Input And Output Relationships In Livestock Production, Sigurd Strangeland Mar 1952

Input And Output Relationships In Livestock Production, Sigurd Strangeland

Agricultural Experiment Station Agricultural Economics Pamphlets (1941-1991)

What are the profitable patterns of crops and livestock for areas in Central South Dakota? This is a question that farmers in South Dakota are especially concerned with at the present time. The farmer is always faced with the problem of planning the most profitable farm organization and operation, but the problem at the present time is emphasized by the current action programs in irrigation and soil conservation which stress the need for more legumes and livestock in the farm organization. If the economist is to aid the farmer and the action programs, an insight to the question posed above …
