Nutrients And Phytoplankton In Hyrum Lake, Robert Bruce Murray

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The current investigation indicates that the routine appearance of a noxious blue-green algal bloom of Aphanizomenon flos-aquae, in Hyrum Lake, a reservoir in northern Utah is a result of excess phosphorus. Data indicate that the algal growth is initiated by phosphorus liberated from the phosphorus rich bottom sediments, and at a time when nitrogen is present in excess in the lake relative to phosphorus.

Results indicate that the Little Bear River is the major source of nitrogen and phosphorus contributing to the eutrophication of Hyrum Lake. Nitrogen and phosphorus fluctuations in the Little Bear River proved to be concurrent with …

The Indentification Of Work Adjustment Problems Of The 1970 And 1971 Manpower Development And Training Program Trainees At Utah State University, Mary Ann Jensen

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

There is a tradition in vocational education which emphasizes teaching technical knowledge and skills while neglecting the development of attitudes and social skills which have been shown to be important causes of problems for office workers. The terms in general use to identify these skills and attitudes are work adjustment and occupational adjustment. Borow calls them " ... the work ethos, a set of attitudes, rules of etiquette, and interpersonal skills involving relations with fellow workers, supervisors, and clients." He goes on to say that:

It is astonishing to what degree the school and the community assume that any student …

Organization And Administration Of The State Aaa Wrestling Tournament Held At Utah State University, Robert Duane Carlson

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Amateur wrestling is one of our finest interscholastic sports. Although it is one of many sports that involves both individual and team competition, the individual wrestler classified according to weight, seems to receive more recognition than in many other sports .

Hence, the ultimate of individual expression in wrestling is the tournament. The growing emphasis on multi-team wrestling tournaments, has presented a problem in organizing and administering such a tournament. Little has been done in the past to help the inexperienced coach obtain the necessary information needed to help him feel confident about volunteering to direct and host a tournament. …

The Young Child's Concept Of Human Conception And Birth, Julie Ann Broberg Puzey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The views held by children about the ere at ion and birth of babies are of importance in child development and developmental psychology. However, most of the research done in this area has been of a theoretical nature rather than empirical. The research shows controversy in the child's concept of human conception and birth, and because of this controversy a study was deemed necessary to find out more of what the young child's concept is of human conception and birth.

The purpose of this study, therefore, was to attempt to determine the extent of children's awareness of the nature of …

Current public awareness programs regarding infant hearing loss were surveyed in the present study and recommendations on a model awareness program of this type were obtained. Fifty-one hearing conservation specialists participated in the …

Assay And Control Of Staphylococcal Enterotoxin A Development In Cheddar Cheese Slurries, Niranjan R. Gandhi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Attempts were made to adapt the microtiter hemagglutination inhibition assay technique for the assay of enterotoxin A. The presence of a potent hemagglutinin in crude and partially purified preparations and the instability of sensitized erythrocytes prevented its use for routine analysis of enterotoxin from culture media and foods.

A capillary tube immunological assay was developed in which 1 μ g of enterotoxin/ml was detected in less than 1 hr . Interfacial reaction of antisera and enterotoxin solutions in a 1 mm internal diameter capillary tube allowed rapid detection and serological typing of enterotoxins.

Staphylococcus aureus growth and enterotoxin A development …

Induction And Initial Characterization Of Male-Sterile Mutants On The Second Chromosome Of Drosophila Melanogaster, Susan M. Graves

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fourteen recessive, male-sterile, autosomal mutants of Drosophila melanogaster were induced using ethyl methanesulfonate. The techniques employed restricted the recovery of mutants to those located on the second chromosome. Eleven of the mutants were male-sterile at 23°C, and the remaining three, though fertile at 23°C, were male-sterile at 28°C. Complementation tests involving all possible pairs of mutations showed each to be located in a unique cistron.

Spermiogenesis in each mutant was studied by light microscopy to determine the stage at which cellular differentiation deviates from normal and to characterize the associated gross abnormalities. Phase contrast microscopy showed that each mutant sterile …

Spermiogenesis In Two Male-Sterile Third-Chromosome Mutants Of Drosophila Melanogaster, Richard F. Wilkinson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An ultrastructural study of sperm differentiation was made on two male-sterile mutants of Drosophila melanogaster. The mutations were induced on the third chromosome with the monoalkylating agent ethyl methanesulfonate and were maintained in stock cultures over a balancer chromosome using a system of multiple inversions. The stages of sperm differentiation, a most dramatic form of cellular differentiation, were then studied at the electron microscope level to determine the effect of the mutations on sperm structure and to correlate those changes with normal sperm development.

Studies of the genetic control of cellular differentiation have been hampered by difficulties in devising …

Radioimmuno Detection Of Virus, John Carlos Perez

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The commonly used techniques for viral detection are tedious, time consuming and in many cases inadequate. As a consequence, a rapid, sensitive radioimmunoassay has been developed for detecting viruses. Reovirus is reacted with homologous ¹²⁵I labeled antibody after which the antigen-antibody complexes are separated from unreacted labeled antibody by density gradient ultracentrifugation. After centrifugation, the density gradient is fractionated and the radioactivity counted in a liquid scintillation spectrometer.

The amount of activity in the lower fractions of the density gradient is directly proportional to the virus concentration. The radioimmunoassay developed has several advantages over other viral assay procedures; the …

Nitrification Potential In Arid Western Soils, Hasumati R. Patel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nitrification rates were determined by perfusion method in Southern Curlew Valley (Utah) soils from 0 to 1.3 meter profiles as a function of seasons. Ammonification rates were determined at various moisture contents and seasonal variations of ammonium concentration in the same soils were estimated.

Rate of nitrification was higher in warm showery periods (May and June) than in colder periods (September, October and November). In the top 3 cm layer, nitrifying activity was several fold higher than in the rest of the profile. Cultivation increased the nitrification rate.

Considerable ammonium fixation by soil particles, volatilazation of ammonia and nitrite accumulation …

A Study Of The Effects Of Water Institutions On Planning And Management Of Water Resources In Utah, Donald H. Mclean

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One area of research that has been somewhat neglected in water planning programs and water development is that pertaining to water law and water institutions. Over the years each state has developed a complex system of water law and organizations for the allocation and distribution of water. The usual role of these institutions is one of orderly development and the efficient use of the water resource. However, in many cases water law and institutions have imposed serious constraints upon the planning and the most efficient use of a valuable resource.

This study, through historic research, has attempted to define these …

The Comparative Effects Of Two Reinforcement Schedules Applied To Groups In Teaching Arithmetic Skills, Ronald C. Bennett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A behavioral approach to teaching in the public school system is difficult because of the inherent difficulty of finding positive reinforcers and administering them simultaneously to large groups of students.

This study attempts to apply the same tangible reinforcers to two groups of students under different schedules of reinforcement. The students in the study were in special classes termed "learning adjustment" classes because of their failure to perform at grade level in regular classroom settings.

One group was on a continuous schedule of reinforcement using tokens and gold strike stamps as reinforcers. The second group was also on a continuous …

Rural-Urban Personality Differences In Utah Adolescents As Measured By The Cpi, Benjamin K. Nelson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The CPI (California Psychological Inventory) was administered to 395 high school students to determine if personality differences exist between rural and urban adolescents in Utah. Of those tested, 219 were selected from three rural schools and 176 were selected from three urban schools.

Ten of the eighteen individual scales of the CPI showed differences between rural and urban students at the P < .05 level. Two of the four classes of scales showed differences at the P < .01 level, and the other two classes showed differences significant at the P < .05 level. In each case where significant differences were found, the differences favored the urban students. The results of this study indicate that the urban students in Utah tend to have more positive personality characteristics than the rural students.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A specific method has been developed for the extraction and measurement of staphylococcal nuclease in cheese in which Staphylococcus aureus has grown. Ten grams of cheese sample were homogenized with ninety milliliters of pH ten buffer for three minutes. Ammonium sulfate fractionation was used and a forty to eighty percent fraction was collected and concentrated using ultrafilters. The nuclease activity was determined using a toluidine blue deoxyribonucleic acid agar slide method and a spectophotometric method. The DNA agar slide method was used to compare staphylococcal growth with nuclease production in cheese under varying conditions. When Staphylococcus aureus plate counts indicated …

Replication: A Teaching Technique And Its Impact On Student Open-Closedmindedness, Dale H. Decker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The problem for the study was the lack of research on the effect of the empirical replication technique on student closed-mindedness. The replication technique requires the student to repeat, or replicate, studies originally conducted by social scientists. In this sense, replication is roughly analogous for the social sciences to what laboratory experiments are for the natural sciences. Additionally, the relationship between college student adjustment-maladjustment and open-closed-mindedness were explored while controlling for sex and academic achievement.

The control group (N=61) attended two lectures and a discussion section per week which dealt with introductory social science materials. The experimental group (N=85) was …

Stimulus Manipulation In Articulation Therapy With A Hearing Impaired Child, Walter Eugene White

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Severely hearing impaired individuals typically exhibit speech that is unintelligible and systematic instruction in speech has not effectively alleviated all of the misarticulations found in the speech of these individuals. Behavior modification is a promising development which has meaningful application to the modification of defective articulation by hearing impaired children.

The purpose of this study was to as certain the feasibility of implementing a specific program of stimulus manipulation to alter the articulation of the |TS| phoneme as uttered by one severely hearing impaired individual. The training program was structured in a sequence of four operant training conditions. Pre-training tests, …
