A Study Of The Effects Of Some Parameters Of The Galloping Of Electric Transmission Lines, Leland J. Coleman Aug 1970

A Study Of The Effects Of Some Parameters Of The Galloping Of Electric Transmission Lines, Leland J. Coleman

Theses and Dissertations

Freezing rainstorms coupled with moderate winds have often been observed to cause telephone lines and power transmission cables to begin bouncing up and down. This slow frequency high amplitude oscillation, or galloping as it is sometimes called, can build up to large amplitudes before the oscillation either damps out or persists at some constant amplitude. It has been reported by Edwards and Livingston [1] that the amplitude of galloping on transmission lines has been as large as forty feet. Galloping oscillations occur at relatively low frequencies; from .1 to 1 Hz. [1] near the natural frequency of the suspended cable.

A Study Of The Electrophoretic Patterns Of Blood Serum Proteins From Two Populations Of Mountain Whitefish (Prosopium Williamsoni), Fred Richard Hansen Aug 1970

A Study Of The Electrophoretic Patterns Of Blood Serum Proteins From Two Populations Of Mountain Whitefish (Prosopium Williamsoni), Fred Richard Hansen

Theses and Dissertations

Electrophoretic patterns on polyacrylamide gels of blood serum proteins from 74 mountain whitefish (Prosopium williamsoni Girard) were examined for differences as they pertained to two geographically isolated populations, age, and sex. Serum samples were acquired from two supposedly isolated populations, the lower Provo River and the lower Weber River. Comparisons among gels were made on the basis of protein distribution as indicated by number of fractions and their density. Serum proteins showed marked intraspecific differences between the males as well as the females of each population. No variations were found which could be attributed to degree of maturity. Definite pattern …

Evolution Of The Iguanine Lizards (Sauria, Iguanidae) As Determined By Osteological And Myological Characters, David F. Avery Aug 1970

Evolution Of The Iguanine Lizards (Sauria, Iguanidae) As Determined By Osteological And Myological Characters, David F. Avery

Theses and Dissertations

The family Iguanidae is almost completely restricted to the Western Hemisphere with its main radiations occurring in North and South America. There are also representatives on Fiji, Tonga and the Galapagos Islands, in the Pacific Ocean. Distantly related forms are also found on Madagascar off the Southeastern Coast of Africa. Although the iguanid lizards are familiar to most scientists interested in the tropics, their anatomy and evolution is poorly understood.

Effects Of X-Irradiation On The Brain Of White Rats, Bernell K. Dalley Aug 1970

Effects Of X-Irradiation On The Brain Of White Rats, Bernell K. Dalley

Theses and Dissertations

With the advent of the atomic age, a great deal of attention has been given to the effects of radiation of various types on the living organism. Some emphasis was placed also on the particular effects damaging radiation has on the central nervous system. Of particular importance was the dis -covery of the high resistance to irradiation exhibited by the central nervous system, and the observation of a latent period after exposure, during which the individual appears normal, followed by deterioration and death. Explan - ations of this unique reaction have caused some controversy and, currently, one of two theories …

The Effects Of Various Treatments On Thiamin Diphosphate And Total Thiamin Levels Of Rat Tissues, Dong Hwa Park Aug 1970

The Effects Of Various Treatments On Thiamin Diphosphate And Total Thiamin Levels Of Rat Tissues, Dong Hwa Park

Theses and Dissertations

Tissue thiamin diphosphate was assayed enzymatically utilizing purified brewer's yeast apotransketolase. With this assay ten uumoles of thiamin diphosphate could be detected. Total thiamin was fluorometrically measured. For one to three days rats were placed under conditions of stress, consisting of loud noise treatment, emotional stress, deprivation of paradoxical sleep, and swimming to exhaustion, respectively. The body weight was markedly decreased at the end of the respective experimental periods except with the loud noise treated group, compared with the corresponding controls. Following two to three such consecutive treatments, the adrenal weight also showed a significant increase. Thiamin diphosphate and total …

The Effects Of Herbicide Applications On The Animal Populations Of Aspen Communities, Carl Eugene Wadsworth Aug 1970

The Effects Of Herbicide Applications On The Animal Populations Of Aspen Communities, Carl Eugene Wadsworth

Theses and Dissertations

Approximately 475 acres of aspen, oak brush, and grass-forb-shrub communities were treated with herbicides. The populations of arthropods, birds, and mammals were investigated on treated and untreated areas and the results were compared. There was no difference between soil arthropod populations on treated and untreated aspen plots but a significant increase in these populations on treated meadow plots. The foliage insect populations were significantly lower on the treated aspen plots but were significantly higher on the treated meadow plots. The aquatic invertebrates were not affected by the treatments. Bird populations ware lower in the treated area during the nesting season …

The Chemistry Of Dehydronaphthalene, Richard Harold Hales Aug 1970

The Chemistry Of Dehydronaphthalene, Richard Harold Hales

Theses and Dissertations

The reaction of monohalonaphthalenes with potassium t-butoxide in a t-butyl alcohol-dimethyl sulfoxide (DMSO) mixture has been studied. The 1-bromonaphthalene reaction was extensively studied. Fifteen identifiable products were observed and conditions were found where the desired products, 1- and 2-t-butyl naphthyl ethers (V and VI) were formed in maximum yield, and their decomposition products, 1- and 2-naphthol (XIV and XV), were formed in minimum yield. The mole percent ratio of 1-substituted products (V and XIV) to 2-substituted products (VI and XV) was found under standardized conditions to be 0.35 ± 0.03 in every case when the halogen was I, Br and …

A Dynamic Model Of A Small Manufacturing Company, Abraham John

Theses and Dissertations

A manufacturing company typically has the objective of maximizing the long-term value of its common stock while satisfying its customers. To achieve this, the company might increase the quantity and improve the quality of production. Since the company is operating in a dynamic environment, its policies should be dynamic also, to achieve its objective.

An Optimization Technique Applied To The Determination Of Modal Damping Coefficients, Craig C. Smith Aug 1970

An Optimization Technique Applied To The Determination Of Modal Damping Coefficients, Craig C. Smith

Theses and Dissertations

Although analytical techniques are generally available for the simulation of dynamic systems, often these techniques require a great deal of computer time and storage. This difficulty was vividly pointed out by a previous thesis undertaken in this Department by R. L. Webster (1). Mr. Webster undertook the determination of orthotropic material properties using dynamic response test data from plates. A major difficulty which was encountered was the enormous amount of computer time required for the simulation. This thesis is an investigation of a method which when fully developed, may provide the ability to simulate such systems much more efficiently.

The Effects Of 2-Chloro-4-Ethylamino-6-Isopropylamino-S-Triazine (Atrazine) On The Activities Of Certain Calvin Cycle Enzymes In Barley And Corn, L. Chris Harrison Aug 1970

The Effects Of 2-Chloro-4-Ethylamino-6-Isopropylamino-S-Triazine (Atrazine) On The Activities Of Certain Calvin Cycle Enzymes In Barley And Corn, L. Chris Harrison

Theses and Dissertations

Atrazine (2-chloro-4, ethylamino-6-isopropylaminos- triazine) applied to Hordium vulgare L. variety barbless in low concentrations (0.001, 0.01, 0.1 uM) was shown to in--­ crease the activity of D-ribulose-1, 5-diphosphate carboxylase (RuDPCase) and phosphoribulokinase (PRuK) up to 23% and 30% respectively and increase the amount of chlorophyll and extractable protein up to 18% and 21% respectively over the control plants. These results indicate that sub-toxic levels of atrazine significantly stimulate plant growth. Barley plants given higher concentrations of atrazine (1.0 and 10 uM) showed up to a 78% and 42% decrease in the activity of RuDPCase and PRuK respectively as well as …

A Comparative Study Of The Head And Thoracic Osteology And Myology Of The Skinks, Eumeces Gilberti Van Denburgh And Eumeces Skiltonianus (Baird And Girard), David F. Nash Jul 1970

A Comparative Study Of The Head And Thoracic Osteology And Myology Of The Skinks, Eumeces Gilberti Van Denburgh And Eumeces Skiltonianus (Baird And Girard), David F. Nash

Theses and Dissertations

Further clarification of the taxonomic and phylogenetic relationships of Eumeces gilberti and Eumeces skiltonianus is achieved by the comparisons of the skull, mandible elements, and the anterior myology of these two species. Figures are provided to compliment the descriptions. The study confirms their close relationship and few differences are observed. E. skiltonianus, however, appears to have more anatomical plasticity which suggests that E. gilberti may have arisen from the former.
