The Effect Of Injected Radioactive Phosphorus On Some Phases Of Reproduction In The Albino Rat, Arland E. Olson

Biology

Damage to the germinal tissue of the ovary by radiation was reported in 1905 by Halberstaedter and by Bergonie and Tribondeau (2). These workers stated only that X-irradiation of the ovary injured the organ and resulted in a marked decrease in size. In 1913 Lacassagne (2) reported the effects of X-irradiation on the ovary of the rabbit. After intensive study he reported that the ovary might be made sterile for a time but that recovery could take place. Primitive ova not killed at the time of irradiation would develop, and the animal could give birth to living young. Since these …

The Effects Of Fertilizers On The Yield, Carotene Content And Tocopherol Content Of Ranger Alfalfa Hay In Utah, Charles Wm. Jones

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Alfalfa is generally regarded as one of the world's most valuable cultivated forage crops. Few crops, if any, are equal to it in capacity to produce heavy yields of highly nutritious, palatable feed. A combination of desirable attributes as a forage plant and adaptation to a wide diversity of soil and climatic conditions has led to the use of alfalfa in the world to an extent probably exceeding that of any other single legume or grass. Alfalfa constantly proves itself as a valuable feed for most types of livestock. This is especially true in the states where a large amount …

Salt Movement And Forage Crop Establishment In A Saline-Alkali Soil As Influenced By Ridges And Furrows, Sprinkler Irrigation, And Soil Amendments, D. C. Purnell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An estimated two to four million acres of irrigable saline and alkali soils of the United States return very little income to land owners (17,19). Increased needs for forage crops, and the relatively high salt and alkali tolerance of some improved forage species, once established, suggests a way of increasing revenue from some of these lands without costly reclamation.

Effect Of Bicarbonate Ion And Root Aeration On Lime-Induced Chlorosis, Willard L. Lindsay

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Chlorosis in plants has been recognized as a devastating disease for over one-hundred and fifty years. It is easily recognized by a yellowing of the plant foilage and is associated with a reduced chlorophyll synthesis.

Chlorosis is found so frequently on calcareous soils that its cause is attributed at least in part to this soil factor. It is therefore referred to as lime-induced chlorosis. This type of chlorosis has become a serious problem, especially in many of the fruit-growing regions of Europe and the Western United States where the soils are calcareous. In Utah the disease is more destructive than …

A Comparison Of Formulae In The Manufacture Of Ice Milk, Glen Wilford Sargent

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ice milk is not a new product in the ice cream industry. Rather it is one that has gained only little popularity, except in the preparation of "malts" and "milk shakes"; however, within the last decade the gallonage of ice milk produced has more than doubled.

Ice milk has been relatively unimportant because of the difficulty of obtaining a product with acceptable quality. In recent years progressive ice milk manufacturers and research workers have discovered new ingredients and processing procedure that seem to produce favorable results.

This low-fat product has several merits that justify its recent popularity, such as low …

A Chromatographic Study Of The Lower Fatty Acids Of Swiss Cheese As A Measure Of Quality, Dee R. Morgan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Importance of project:

A sweet hazelnut flavor, a pliant texture, and large, evenly distributed "eyes" characterize high quality Swiss of Emmenthaler cheese. The typical sweet flavor is chiefly due to bacteria which produce propionic acid, acetic acid, and carbon dioxide. The eyes are formed from the gas, mainly carbon dioxide, produced by these and other bacteria.

Krett and Stine (20) have found that the lower fatty acid content of a Swiss cheese generally indicates its quality.

A study of factors which may influence the amount and ratios of the volatile acids should be helpful in determining manufacturing and curing procedures …

The Influence Of Amounts Of Propionibacterium Shermanii On Eye Formation And Flavor Of Swiss Cheese, Dan G. Turner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Swiss cheese has been rightly called "king of the cheeses." It has been prized the world over for its stately appearance and sweet "hazelnut" flavor. In grading Swiss cheese, these two things,appearance and flavor, are important considerations in determining the cheese score. Appearance is judges according to the number, type, and size of eyes present in the cheese, with color and body and texture also considered. Flavor is judges according to the degree of sweetness and the amount and kinds of off flavors present.

In the past, there has been considerable variation in the quality of the Swiss cheese produces. …

The Beginnings Of Settlement In Cache Valley, Joel Edward Ricks

Faculty Honor Lectures

In our picturesque valley, virtually surrounded by mountains, watered by beautiful streams, filled · with rich soil, and covered by willows, sagebrush, and plentiful grasses, inhabited by beaver and other wild animals, the trapper, the explorer, and the pioneer found the answer to their quest for beauty and the search for an abundant living.

Bulletin No. 360 - The Effects Of Fertilizer And Moisture On The Growth And Yield Of Sweet Corn, H. B. Peterson, J. C. Ballard

UAES Bulletins

Sweet corn is becoming an important cash crop in many of the irrigated valleys of the Intermountain West. There are a number of factors that influence the yield of this crop, two of which are soil fertility and moisture. A number of investigations have been conducted where the effects of fertilizer have been measured, and the results of these investigations have been highly variable. In general, however, lack of nitrogen has been a major factor limiting yield.

The Content Of Pantothenic Acid, Folic Acid And Vitamin B12 Like-Activity In Alfalfa Hay Grown In Utah Soils Treated With Different Fertilizers, Buranaphoka Kashemsri

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Vitamins play an important role in the nutrition of man and animal. As early as 1897 Eijkman was able to demonstrate the symptoms of thiamine deficiency disease in birds. Since then, vitamins have been regarded as one of the most essential factors in nutrition. Only small quantities in the diet are necessary, yet lack of any of them will inhibit the growth and produce certain kinds of deficiency diseases.

The Uptake Of Iron By Bean Plants As Influenced By Age, And Calcium And Bicarbonate Ions In Solution Cultures, Michael Marcour

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Chlorosis of the foliage of higher plants has constituted a severe fertility problem in many areas of the world. It has been reported in no less than 30 countries. It has manifested itself in the western states and has usually been associated with a high CaCO₃ content in the soil.

This chlorosis does not always result from lack or unavailability of one of the essential elements, but can result from several conditions around the plant roots or psychological processes taking place within the plant. Both the absence of iron in the Boil and conditions which provoke its unavailability to …

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 Survey Of Extension Work In Wildlife Management And The Development Of A Guide To Wildlife Extension Work In Utah, Edwin V. Rawley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The most efficient wildlife research programs and the most satisfactory methods of applying their results are greatly enhanced if the information is present in such an interesting and understandable manner that it becomes of practical value of the people. Extension education has the function of translating the results of research into usable form and presenting it to the people. The development of a wildlife extension program is based on the needs of the people, and the various phases of the program are designed to meet and solve wildlife problems confronting the people. The purposes of this study are: 1. To …

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 …

Factors Determining Fruit Set And Seed Development In Artificially Pollinated Tomatoes, Charles Howard Henry

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Commercial plantings of tomato hybrids will give increases in earliness and yield because of hybrid vigor, but seed costs become a limiting factor. The necessity of hand-pollination makes the production of first generation hybrid tomato seed a costly enterprise. Failures of fruit set and seed development in artificially pollinated tomatoes are two contributing causes for the increased cost of F₁ seed.

The purpose of this investigation is to study some basic factors influencing these failures and to find ways of increasing fruit set and number of seeds per fruit.

The scope in addition to the field studies described includes …

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 …
