Biology And Control Of The Rose Stem Girdler, Agrilus Rubicola Communis Obenb., On Raspberry, Nuggehalli N. Raghuvir

Biology

The first red raspberries were cultivated in Europe 400 years ago. They were grown for the first time in the United States some time before 1800 (Gourley and Howlett, 1941). The cultivation of raspberries is limited largely to the northern part of the United States, chiefly in the cool, temperate areas. Areas from which extensive quantities of red raspberry are shipped are located in southern New Jersey, in the Hudson river valley, in western Michigan, in the Puyallup valley of Washington, and near Sebastopol, Washington.

The Price Of Prejudice, Leonard J. Arrington

Faculty Honor Lectures

When the Japanese attacked Pearl Harbor December 7,1941, about 127,000 persons of Japanese descent were living in the United States, of whom more than 112,000 were on the Pacific Coast. These could be conveniently divided into three groups: the Issei or immigrants born in Japan; the Nisei or American-born, American-educated children of the Issei;' and the Kibei, who were born in America but received some of their education in Japan.

Permanently excluded from becoming American citizens by United States law, and seriously limited in their ability to acquire agricultural and residential property by alien land laws, the 40,000 Issei had …

A Study Of A Bacterial Cause Of The Late Gas Defect In Cheddar Cheese, Rulon A. Chappell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

More of the manufacturing milk purchased from Utah's dairy farms is used for the production of cheese than for any other product. Approximately eleven and one-half million pounds of cheese were produced in Utah in 1959, of which more than half was cheddar. Many problems are encountered in the production of A-grade cheddar cheese. One of the most important causes of the reduction in grade is the late gas defect which accounts for about 50 percent of the cheese grading below A-grade. To increase the percentage of A-grade cheddar cheese in Utah, the late gas problem should be solved. The …

An Evaluation Of Social Stars, Regulars, Neglectees, And Isolates In Ability-Grouped And Random-Grouped Classrooms, Benjamin W. Standing

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Education in the United States attempts to present maximum opportunities for learning in a democratic atmosphere. Many great educators have sought means to accomplish this end. Today, because of the stimulating force of other nations, even greater pressure is being brought to bear to achieve these goals. The plan of grouping pupils according to their abilities has been presented as one way to facilitate learning.

Ability grouping is the assigning of pupils who are essentially alike to special grade levels and to parallel sections of the same grade. Although it may be thought that ability grouping is a new procedure, …

A Comparative Analysis Of The Effects Of Heterogeneous And Homogeneous Elementary School Grouping Practices On Selected Personality Variables, Clarence D. Swaner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The relative advantages or disadvantages associated with the practice of grouping school children according to ability level has long been the subject of considerable discussion among educators. The general tendency has been for educators to divide into two camps: Those who expound the various merits of homogeneous grouping, and those who favor and support heterogeneous grouping practices. Less common, but acknowledged, are those educators who favor a combination of the two methods. Research dealing with the relative value of either method has usually been concerned with only one aspect of the problem--that of academic achievement. However, the efforts of several …

A Study Of The Self-Selection Method Of Reading In The Sixth-Grade Of The Ephraim Elementary School, Elliot J. Arnoldson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As educators have searched continuously for the best method to teach reading, numerous techniques have been advanced. Some of these techniques are comprised of basic elements in reading which are proven and used with much success and security on the part of the teacher. Others are tried, used, made popular for a short time and then are cast aside as in adequate teaching methods.

That learning to read is an individual matter no educator will deny. Nor is it controversial to say that, within each person's generalized reading ability, there exists unevennesses in skills development. Nor does anyone question that …

A Study Of Sprinkler Uniformity Evaluation Methods, Baha Dabbous

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The use of water in homes, on farms, by factories, and for recreational purposes has been increasing rapidly. Water use has doubled in the last three decades. By 1980, water use is expected to be double the current use. In arid and semi-arid regions, the practice of successful profit-yielding agriculture often depends on irrigation. Irrigation is, in turn, dependent upon a water supply which is limited. The highest possible efficiency should be maintained if maximum utilization of the available water resources for irrigation is desired. Sprinkler irrigation allows, among other things, high water application efficiencies with good distribution uniformities.

Selected Insecticides In The Control Of Invertebrates Possibly Associated With Avian Botulism, J. Larry Haddock

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Avian botulism or ''western duck sickness" has long been a major problem on duck marshes in the western part of the United States. This has been demonstrated to result from the ingestion of products of metabolism of bacterial cells of Clostridium botulinum type C. These products when ingested by waterfowl act as neurotoxins (Coburn, 1942). Studies have shown that many animal tissues are readily utilized as culture media by Cl. botulinum type C (Bell et al., 1955).

Since 1955 investigations have indicated a close relation between the occurrence of avian botulism and invertebrate population levels. It is thought that when …

The Effects Of Radium On Certain Goldfish Blood Constituents And Organs, D. Wayne Linn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Background radioactivity from radium has long existed in ground and surface waters of the United States, but in the last 15 years radium has become a consequential unnatural contaminant of waters (Coulomb, 1955; Rone, 1952; Schlundt, 1910; Scott and Barker, 1956; Scott, 1961; and Tsivoglou et al., 1958). The onset of the atomic age initiated the increased processing of uranium ore for its uranium content. Radium is a daughter product and a by-product of uranium ore and its purification (Glasstone, 1958; and Tsivoglou et al., 1958). The uranium refinery wastes are released into streams in which all forms of aquatic …

Student Teacher Attitudes Toward Child Aggression And Dependency In A Child Development Laboratory, Kristine Halls Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A child development laboratory in a university finds its first justification in its ability to contribute to the education of college students. After this justification has been established, the laboratory has a responsibility for serving the children enrolled in it.

The Child Development Laboratory at Utah State University serves college students in several ways. Students are able to observe and participate in the nursery school laboratory through experiences in various courses. The culmination of their course work comes when, as juniors or seniors, they do student teaching in the nursery school.

Some of the purposes the nursery school attempts to …

Comparative Marital Adjustment Of A Selected Sample Of Active And Inactive L.D.S. Church Members, Paul K. Winward

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis is a study dealing with active and inactive L.D.S. couples and their comparative Marital adjustment. The couples were selected from the geographic areas of Enterprise and Logan, Utah, and Preston, Idaho. Respondents consisted of couples who had at least one child, but no children beyond high school age. Their religiosity was determined by the bishop of the L.D.S. Ward of which they were a member. The bishop considered such factors as attendance at regularly scheduled church meetings and contributions made in the form of tithes in determining whether a couple was considered active or inactive. The sample consisted …

Differences In Frustration Reactions Of Nursery School Children, Sharon Marshall

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The study of frustration has been of interest to various people including psychiatrists, psychologists, and educators for a number of years. These people have been interested in frustration because the complexity of our modern life has involved so many frustrating experiences. Frustration has been defined by Dollard (8, p. 7) as "an interference with the occurrence of an instigated goal response at its proper time." Ruch (21, p. 151) defined frustration as "the denial or thwarting by some obstacle which lies between a need and its goal." These two definitions are in essence identical. The average person has many obstacles …

Educational Grouping And Students' Self Concept, John N. Giboney

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The question of ability grouping in education has achieved prominence, especially in recent years. Much of the emphasis placed on grouping students according to ability rather than chronological age is a product of modern times and progressive education. Although not accepted by all educators, there is a definite movement toward such a procedure in public schools today. It is held by the advocates of ability grouping that students will benefit more in a situation where they proceed at a rate prescribed by their ability rather than a hypothetical average or norm. Several well-controlled studies (3, 33, 44) have shown that …

A Comparison Of Aspiration Levels Of Students In Ability-Grouped And Randomly-Grouped Schools, George Aaron Jeffs

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Grouping students with in the school setting has long been a concern to all those associated with the educative process. Much investigation has been devoted to the position of level of aspiration as influential motive forces for educational, occupational, and social achievement. Many avenues of grouping have been investigated and some very thoroughly. However, research concerning grouping in relation to level of aspiration in the school setting appears to be extremely limited. This study is designed to further investigate this issue. It might be said that this study consists of essentially two phases: (1) the development of instruments for measuring …

The Use Of Objective Physical Measurements And Specific Selling Methods As A Basis Of Marketing Wool Through Pools, Don A. Huber

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wool has been an important product in Utah since the pioneers arrived. The Mormon pioneers had with them 358 head of sheep upon entering the Salt Lake Valley. At that time there were also 12 head of sheep near Ogden, Utah belonging to Miles Goodyear, a trading post operator. These early people were very dependent upon wool for their clothing and numerous other products.

Influence Of Age On Milk Production Of Holstein Cows In Utah, Marvin R. Green

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Production of dairy cows is influenced by many factors, among which are: genetics, nutrition, management, disease and age. Most of these factors can be modified to maintain a high level of production. Age, however, is beyond the influence of mankind; therefore, it is important to understand the effect of age on milk and butter-fat production.

Forage Yield And Plant Stand Intensity Of Nine Alfalfa Varieties In Relation To Nine Rates Of Seeding And Bacterial Wilt Resistance, Hamid Auda

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In growing alfalfa it is important to obtain a good initial stand. However, it is difficult to predict the exact amount of seed necessary to insure a good stand.

There are about 220,000 seeds in 1 pound of alfalfa seed, or enough for four to five seeds per square foot at the rate of 1 pound of seed per acre. If every seed should grow, 2 to 3 pounds of seed per acre would be sufficient for a good stand.

However, there are many hazards. Some seeds are not viable, and others are planted too deep or too shallow to …

The Cost Of Owning And Operating Farm Power And Machinery Used In Tillage Operations On Diversified Farms In Selected Areas Of Utah, 1960, Clynn Phillips

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A current problem facing farmers is, how much should they mechanize their farm perations? As the relative price and productivity of factors change farmers usually have to adjust their operations to assure maximum profits. Technological advances often change the relative productiveness and the price of machinery. These changes have caused the progressive farmer to continually review his farm organization and make adjustments in levels of factor use. If he is to produce at maximum profits it is necessary that his machinery investment be in proper adjustment with other resources.

Quality Evaluation Of Certain Fruit Jellies And Syrups Prepared With Sucrose, Sorbitol, And Synthetic Sweeteners, Sandra Louise Day

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Body weight is fast becoming the major health problem in the United States. Recent estimates of the number of weight conscious people in the United States are now up to 75 million. One year ago the estimate of overweight individuals was 60 million Americans who were overweight or should be concerned about watching their weight. There are also two million known diabetics who must control their disease and body weight by a restricted caloric intake.

Experiments On The Origin And Nature Of A Zinc Deficiency Of Field Beans On A Portneuf Soil As Determined By The Application Of Zinc 65, Edgar Dale De Remer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In a few instances an agricultural problem lend itself well to research into some of the more basic aspects of a problem as well as to research to determine the exact nature of the problem ad to prescribe a cure. Such a problem was found by the author to exist on a soil of the Twin Falls, Idaho area. Besides making an attempt to ascertain the exact nature of the problem, an experiment was set up in an attempt to understand more about the mechanism responsible for the problem.

Group Grain Feeding Versus Individual Grain Feeding Of Lactating Dairy Cows, Earl Max Sudweeks

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Grain feeding is an important part of a dairy feeding program. Grain supplies energy in a concentrated form and when fed as a supplement to forage permits cows to maintain high levels of production. Also, if the forage is of low quality, additional protein and other nutrients can be supplied with the grain in a concentrate mix. By feeding a balanced concentrate mix, according to individual production, each cow receives the necessary nutrients for production. Dairy cows are usually fed grain individually.

The Effect Of Chelates On Phosphorus Availability And Mobility, Salah Ahmed Tahoun

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Soil-phosphorus relations and plant-phosphorus relations have attracted the interest of many investigators since Liebig introduced his famous theory about the importance of the mineral matters to the plant in 1840. It was soon realized that phosphorus nutrition was a problem not easily solved for two reasons. 1. The added phosphorus fertilizers, soon after soil application are converted by some reactions in the soil to complex compounds far less soluble, consequently less available to the plant. Conclusions about this process led to controversial debates until it was discovered that a general statement covering all soils was impossible since the reactions involved …

Relations Between Transpiration, Leaf Temperatures, And Some Environmental Factors, Ronald Kay Tew

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Transpiration is the loss of water in vapor form from a plant. This is essentially the same process as evaporation except that it is modified by plant structure. Large quantities of water are removed from the soil, transferred through the conducting tissues of the plant, and dissipated into the air each day. As soon as the water is lost to the atmosphere, it becomes unavailable for human use.

The Effect Of Range Condition Upon The Production, Nutritive Intake And Digestibility Of Desert Range Forage In Southwestern Utah, J. Kent Taylor

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The 65 million acres of winter range in the Intermountain region furnish forage for about five million sheep and four million cattle each winter for approximately six months. These arid ranges are well suited for winter grazing, and are of paramount importance to the livestock industry. Many of these ranges were fully stocked by 1900 and as livestock continued to increase, many winter ranges were seriously over-grazed (Hutchings and Stewart, 1953). Today many of these ranges remain in a deteriorated condition. Forage production has decreased and desirable plants have been replaced by less desirable species.

Little is known about the …

Complexing Of Sugars And Polyhydroxy Alcohols With Molybdenum (Vi), Su Chin Kiang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Molybdenum is very important in the life processes of both plants and animals. It acts as a catalyst in promoting and controlling many biological reactions in living cells, but exactly what it does and how it functions are not well understood. In the past because of the obvious complexity of the reactions concerned and the extremely minute quantities of molybdenum involved, its presence was long undetected. Lately, molybdenum has drawn special attention on account of its effects on metabolic processes, particularly of plants. In this regard, molybdenum has been shown to be present in four enzymes: nitrate reductase (JJ), xanthine …

The Influence Of Internal Moisture Deficit On Translocation, Sven Egenolf Wihrheim

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The reduced growth of plants under conditions of moisture stress has been attributed to reduced turgor necessary for cell enlargement and to reduced photosynthesis often found in wilted or moisture stressed plants. Reduced translocation is rarely mentioned as a factor in reduced plant growth under limited moisture. This is rather surprising, since the Münch pressure flow hypothesis would require a turgor pressure gradient between leaves and receiving organs before any translocation of sugars could occur. Such a turgor pressure gradient would be reduced with increasing internal moisture deficit and would appear to become zero when the leaves wilt. If this …
