Sodium And Potassium Nutrition Studies Of Halogeton Glomeratus (M. Bieb) C.A. Mey, Ali A. Alhelal

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Halogeton glomeratus (M. Bieb) C.A. Mey when grown in nutrient solution, caused the solution pH to decrease very rapidly as plants increased in size, especially during the fifth week of growth. This might be attributed to hydrogen ion exchange for cations. Also, the cation uptake, especially K and Na, may exceed that of the major anions. The control of pH is effective in increasing shoot weights markedly.

In general there was no difference between plants grown at the same NaCl concentration at low and high relative humidity. An increase in plant size, shoot weights, leaf length and diameter was detected …

Coyote-Prey Relationships In Curlew Valley During A Period Of Low Jackrabbit Density, Stephen W. Hoffman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Coyote-prey relationships were examined in Curlew Valley, northern Utah and southern Idaho, during a period of low jackrabbit density (from September 1973 to May 1975). The Utah and Idaho portions of Curlew Valley were treated separately. Field work provided estimates of relative and absolute rodent densities as well as relative coyote density each spring and fall. Laboratory analysis of over 2,300 scats and 249 stomachs provided detailed information on coyote diets. Jackrabbit population data for northern Utah were obtained from L. Charles Stoddart.

Four species, Peromyscus maniculatus, Perognathus parvus, Eutamias minimus, and Dipodomys ordii comprised over 90 …

Estimation Of Floods When Runoff Originates From Nonhomogeneous Sources, David Ray Olson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Extreme value theory is used as a basis for deriving a distribution function for flood frequency analysis when runoff originates from nonhomogeneous sources. A modified least squares technique is used to estimate the parameters of the distribution function for eleven rivers. Goodness-of-fit statistics are computed and the distribution function is found to fit the data very well.

The derived distribution function is recommended as a base method for flood frequency analysis for rivers exhibiting nonhomogeneous sources of runoff if further investigation also proves to be positive.

Finally the data indicated that over 75% of the counselors participating …

Energy Management Study Of Irrigation Pumping Plants For The Utah Power And Light Company, Jeffrey C. White

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

All electric power utility companies are faced with yearly peak demands. They must supply sufficient generating capacity along with transmission and distribution facilities to carry these loads. In the past, peaking requirements of many utilities have been met by the use of gas turbines, which are not as efficient as base load plants, but require substantially lower capital investments. However, the fuel supplies used for gas turbines are becoming extremely difficult and expensive to procure and as a result, other means for meeting peak demands are being examined.

Energy management attempts to modify the power systems' load requirements to fit …

Development Of A Liquefaction Opportunity Map For Cache Valley, Utah, Richard J. Greenwood

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A liquefaction opportunity map was developed for Cache Valley, Utah. The study was the initial phase to determine the potential for liquefaction in Cache Valley.

The method used in this study to develop the liquefaction opportunity map was based on a procedure developed by Youd and Perkins (1977).

This opportunity map is proposed to be combined with a map delineating liquefaction susceptible soils to produce a liquefaction potential map. The liquefaction susceptibility map is being developed in a companion study.

The liquefaction potential map will assist in the evaluation of earthquake response in general and microzonation in particular. The liquefaction …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The author investigated the effects of abrupt and graduated temporal reductions on academic performance. Six elementary school children who were referred to a remedial special education classroom received token reinforcement contingent on the number of correct math problems answered during daily sessions. A multiple baseline across subjects design with replication of baseline and experimental conditions was employed. The design also balanced the order of exposure to an abrupt reduction in time limits (20 - 5 - 20 min.) and a graduated sequence of time reductions (20 - 15 - 10 - 5 - 20 min.). Children also performed copying tasks …

Causative Factors And Some Consequences Of Dystocia In Two-Year-Old Heifers, Delyn Jensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Causative factors and some consequences of dystocia were examined in 3923 parturitions among Hereford and Angus x Hereford crossbred two-year-old heifers. Fifty percent of the parturitions required some assistance. Minor assistance was required in 34.5% of the parturitions and major assistance involving use of a calf puller, in 15.1%. Caesarean section and foetotomy were rendered in 0.3% and .05% of the cases, respectively. Abnormal presentation at birth, which included leg back, head back, backwards, hiplock and breech, was observed in only 2.9% of the births and therefore is a minor contributor to dystocia. The major causes of dystocia were not …

The Use Of Symbolic Modeling On Generalized Imitation In Children, Emmett G. Anderson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ten experimentally naive children between the ages of six and eight served in three generalized imitation experiments using symbolic models. Subjects were presented videotaped behaviors to imitate via closed circuit television, and their responses were mechanically defined, recorded, and reinforced in an effort to control social influences from the presence of the experimenter. In Experiment 1, imitation of three behaviors was reinforced and imitation of a fourth behavior was never reinforced for four subjects. Two other subjects received noncontingent reinforcement. The following independent variables were tested: (1) the presence and absence of an experimenter, (2) instructions to "Do that," and …
