A Rationale For Furrow Irrigation System Design And Management, Safa Noori Hamad

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Mathematical and computerized models are developed to design and optimize furrow irrigation systems. The optimization process starts with land grading design, if any is needed, followed by a prediction of maximum non-erosive furrow stream size allowed on a given soil and the associated furrow-advance function. An average depth of application per irrigation is then assumed from which the wetting pattern along the furrow and the amounts of runoff water are predicted. A design of an Irrigation Runoff Recovery System, IRRS, is then executed, if desired, and system cost is determined. Using the predicted wetting pattern and the appropriate Crop Production …

Comparisons Of Body Activity In Depressed, Manic, And Normal Persons, Bron B. Ingoldsby

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Films of three depress ed persons, one manic, and one normal individual were analyzed frame-by-frame to determine body activity rates. Speech rates were also determined. It was found that the manic had the highest activity rate, followed by the normal comparison, and with the depressed patients having the lowest activity rates. The depressed subjects also had lower speech rates than did the normal or the manic subjects. The term 'psychomotor retardation 1 is called into question, as the frequency distributions of movement durations were similar for all subjects. Implications for treatment and for development are also discussed.

Assessment Of Possible Carcinogenic Hazards Created In Surrounding Ecosystems By Oil Shale Developments, Gerald L. Dassler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One of the purposes of an environmental assessment is to foresee potential problems created by the introduction of contaminants into an ecosystem and to suggest appropriate control devices to mitigate the effects of such inputs. In the case of the oil shale industry, very little is known about the potential hazards, especially those related to the emission of organic compounds with carcinogenic potency. The hazards will probably be due to chronic exposures to the emitted compounds and the effects of such exposures are likely to take years to manifest themselves, as is the case with many carcinogenic substances. A precise …

Quantitation Of Aliphatic Aldehydes In Rancid Turkey Meat Using A Substituted Hydrazone, Stanley J. Andrews

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many objective chemical tests have attempted to correlate with organoleptic evaluation of oxidative rancidity. Major chemical tests used to detect oxidative rancidity of lipids measure nonvolatile high molecular weight carbonylic substances which make no considerable contribution to rancid flavors. High molecular weight carbonyls are present at much greater concentrations than volatile low molecular weight carbonyls. Peroxides and other unknown substances also react in these chemical tests to give at best an empirical evaluation. A 3-methyl-2-benzothiazolinone hydrazone chemical test is proposed which corrected some deficiencies of earlier procedures, and was correlated with organoleptic evaluation of rancid turkey samples. The proposed test …

Some Effects Of Mechanical Deboning On The Composition And The Bioavailability Of Protein And Iron In Turkey Frame Meat, Lowell C. Allred

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Meat was obtained from a single daily lot of turkey frames by mechanically deboning with a Beehive AU 4171 deboner and by hand deboning. The meat was analyzed for protein, fat, moisture, ash, iron, calcium, and 19 amino acids. Mechanically deboned turkey had 68 percent more ash, 74 percent more iron, and nine times more calcium than the hand deboned turkey meat. Other constituents were about equal in the two products. Protein bioavailability tests, including protein efficiency ratio, biological value, net protein utilization, and nitrogen efficiency for growth, did not reveal significant differences between mechanically deboned and hand deboned turkey. …

A Longitudinal Study, Part Iii: The Relationship Of Weight, Health Status, Diet And Anxiety To Serum Cholesterol Levels In Adults, Kristine S. Saunders

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Over an 18-year period, beginning in 1955, a group of subjects has been studied six times to determine if any relationship exists among serum cholesterol levels, body weight, health status, diet quality and stress or anxiety. For the first four test periods, extending through ages 7 to 16 years, there were 321 subjects. Later, in 1968, 86 of the original 321 subjects, now aged 19-22 years, were able to participate in a follow-up study. The 1974 study was able to involve 30 of the original 321 subjects now aged 26-29 years. Findings show that from approximately the fifteenth year onward …

The Role Of Zinc In Insulin Metabolism In The Pancreas Of The Rat, Chih-Chi Liaw

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A series of in vitro trials have been conducted to determine what relationship exists between zinc and the insulin mechanism.

There were no significant differences of the zinc contents in total pancreases excised from the rats thirty minutes after the intraperitoneal glucose dose or from the non-dosed controls. When pancreases were cut into three pieces, and treated in three ways: Incubated without glucose (IWG) followed by isolation of the islets; incubated with glucose (IWG) followed by isolation of the islets; islets were isolated, then incubated with glucose (IWG). The zinc content in the islets was significantly higher (p < 0.01) in the first group than the others.

The insulin …

The Incidence Of Child Abuse And Neglect In The Population At The Utah State Industrial School, Jeff Clark

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

There has been some speculation that abuse/neglect may lead to later antisocial behavior by the abused/neglected child. It was the purpose of this project to determine the frequency of abuse/neglect in the population at the State Industrial School and to compare the types of crimes committed by abused/neglected delinquents with those delinquents not abused/neglected.

The subjects consisted of all the adolescents committed to the State Industrial School. During the research project, 159 adolescents were at the State Industrial School. Of those, 63 had data in their files indicating some form of abuse or neglect.

The findings of the study showed …

A Hydrology Temperature Model For A Small Mountain Watershed, Charles Wilson Pettee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A small mountain watershed located in the Wasatch Mountains of North Central Utah is calibrated to a lumped, deterministic simulation model which is capable of predicting daily streamflow and stream temperature. The input information required is daily precipitation and maximum and minimum air temperatures.

In this study, the area of watershed modeling is reviewed in general and as it specifically applies to the study watershed.

The degree of correlation between observed data and predicted output is only mediocre. The model remains unverified for streamflow prediction and is poorly verified for stream temperature.

Irrigation Scheduling Program For Sugarcane, Terence L. Pearse

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An estimate of potential evapotranspiration is acquired to implement an irrigation scheduling program. Four equations, which estimate potential evapotranspiration (evaporation) were evaluated for prediction of Class "A" Pan evaporation. The equations used were Penman's combination equation, the Jensen-Haise temperature and radiation equation, and two of the Christiansen-Hargreaves polynomial regression type equations. Measured and calculated radiation was used together with two values of albedo. Four years of daily climate data from Rhodesia was evaluated by general linear regression methods.

Despite the significant variations between the four annual regression lines of each equation, the use of confidence intervals indicate that the Penman …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Food-searching behavior of two adult male Ferruginous Hawks (Buteo regalis) was studied by direct observation in Curlew Valley, Utah-Idaho, during the nesting seasons of 1974 and 1975. This paper analyzes the effects of vegetation type, prey distribution, cover density, previous experience, and time and energy budgets upon the predators' choice of hunting methods and hunting sites.

Both hawks hunted actively throughout the day (0600 to 2100 hours MDT). Male 1 (1974) and Male 2 (1975) captured an average of 8.7 ± 2.0 and 9.0 ± 1.5 prey items per day, respectively, during the 4-wk observation period in each …

Forage Selection And Nutrition Of Sheep And Goats Grazing In The Tunisian Pre-Sahara, Rudolfo Ricardo Griego

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nomadic pastoralism has been the traditional method of utilizing grazing resources in arid and semi-arid regions of Africa. However, increased sedentarization accompanied by growing human and animal populations during the past two decades is thought to be accelerating the desertification process, or desert expansion. The specific interactions of the grazing animal with this process has been speculated upon but not studied in detail. A comparative study was initiated during the spring grazing season of 1974 to determine sheep and goat nutritional and production responses, as well as patterns of vegetative selection and utilization under the pastoral system currently employed in …

The objectives were (1) the comparison of inmates who had indicated that they had attempted suicide in their past, referred to as "suicide attempt inmates," with inmates who had not, referred to as "non-suicide attempt inmates," on 33 behavioral and personal variables; (2) The development of a suicide attempt scale by means of an item analysis on the responses of suicide attempt and non-suicide inmates to the items of the Bipolar Psychological Inventory (BPI). This scale was named …

The Identification Of Characteristics Of The Hyperactive Child Through Objective Evaluation, Joan Elaine Owen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

For many years adults have been concerned about the hyperactive child, who acts out in a boisterous manner, who is perhaps too physically stimulated and who is often perceived as not meeting adult expectations. It seems important to identify the characteristics of the hyperactive child in an objective and understandable manner so that parents, teachers, medical doctors, and mental health practitioners can determine more adequate prescriptive treatment programs.

The purpose of this study was to adjudge whether children referred for psychoeducational evaluation by pediatricians as hyperactive exhibit behavioral characteristics which, when evaluated by standardized tests, are significantly different from those …
