Solids-Liquids Separation In Coal Solution Technology, Ferdosh D. Nankani

Theses and Dissertations

An alternate method to the conventional filtration for separation of mineral matter from dissolved lignite was investigated. Separation was accomplished by the introduction of an organic diluent mixed with the solid-liquid product from hydrogenation-solubilization of lignite and decanted at elevated temperatures and pressures. This method gave separation as high as 88 percent recovery of solvent refined lignite (SRL). The SRL contained ash as low as 0.70 percent versus 0.1 to 0.6 percent ash obtained by filtration methods.

The technique investigated is analogous to methods used in the deasphalting of petroleum residuum employed in the petroleum industry. The introduction of the …

A Study Of The Ontology Of Evil In The Educational Philosophy Of Martin Buber, Laud Oswald Vaught

Theses and Dissertations

Martin Buber preferred to be known as a philosophical anthropologist rather than a philosopher, theologian, or teacher. Any of these titles are properly used since the scope of his writings contribute significantly to each of these fields.

It is the purpose of this paper to show that what he had to say concerning the Ontology of Evil is significant in the study of educational theory and that his own educational philosophy was influenced by his presuppositions concerning the nature of evil.

Chapter II is devoted to the literature relating to the basic elements of this study: the problem of evil, …

Attraction Of A Senior Citizen To A Hypothetical Stranger As A Function Of The Stranger's Age, Sex, And Attitude Similarity, Carl R. Westphal

Theses and Dissertations

The present study was designed to examine the variables which affect attraction in a senior citizen population. In particular, variables which have been shown to affect attraction in younger persons were examined as to their relevancy to older subjects. It was predicted that a stranger’s age, sex, and proportion of similar attitudes would have a significant effect on a senior citizen's attraction rating of the stranger.

A stranger’s age, sex, and proportion of similar attitudes were varied according to a 3 (proportion of similar attitudes) X 3 (age of stranger) X 2 (sex of stranger) factorial design. Male and female …

Behavioral Effects Of Postnatal Zinc Deficiency And Kryptopyrrole In The Rat, Peter C. Peterson

Theses and Dissertations

Zinc deficiency has been shown to have a wide range of behavioral effects in the rat. The experiments presented below were conducted to determine the effects of postnatal zinc deficiency (birth-21 days) on avoidance learning and on measures of emotionality. Kryptopyrrole, a substance which has been shown to produce "catatonic" freezing behavior and atypical electrical activity in rat brains, was administered to half of the Ss to study possible zinc deficiency-kryptopyrrole interactions.

Dams were made zinc deficient from the day of delivery until day 21 on a diet contaning less than 1 ppm zinc. Two dietary control groups were used: …

Personality Dimensions Of Drinking Patterns In Hospitalized Male Alcoholics, Donald J. Mccullagh

Theses and Dissertations

Research concerning alcoholism and personality has often been based upon the single syndrome concept of alcoholism. At the theoretical level it has been recognized that different personality patterns exist among alcoholics. However, few researchers have addressed themselves to this area. The purpose of this study was to determine whether a relationship existed between alcoholic drinking patterns and alcoholism severity based on the responses to the Alcohol Use Questionnaire and personality traits as measured by Cattell's Sixteen Personality Factor Questionnaire.

The sample consisted of 101 white males admitted to a midwestern alcoholism treatment center during a three month period in 1974. …

Ecology Of Sago Pondweed (Potamogeton Pectinatus L.) Communities, Alden L. Kollman

Theses and Dissertations

Potamogeton pectinatus L., a submerged, marl forming macrophyte, grows as a natural monospecies community in Fox Lake, 16 km northeast of Devils Lake, North Dakota. The water, sediment, dissolved oxygen, temperature and productivity relationships were studied in this small (0.4 X 1.2 km), shallow (60-75 cm) lake. Five replicate samples of the macrophyte, sediment, water and dissolved oxygen were taken at two week intervals during the 1972 growing season. In August of 1973, seven P. pectinatus sites in North Dakota, from the Minnesota to the Montana borders, were sampled. The sediments were analyzed for pH (7.8), electrical conductivity (9.8 Mmhos/cm), …

Early Postnatal Zinc Deficiency And Aggression In The Rat, Mark J. Hanlon

Theses and Dissertations

The effects of a transitory zinc deficiency on subsequent aggression were assessed. Eleven Sprague Dawley dams were assigned to three dietary conditions.on days 1—21 postpartum. They were fed either a low zinc diet (less than 1 ppm) or an equal amount of the same diet but with zinc supplementation via their water supply, or unrestricted amounts of the zinc supplemented regimen. Within the first two days postpartum, litter sizes were equalized. All dams were returned to zinc adequate diets on day 22, and the pups were weaned on day 24. Food intake data for pups and dams were recorded as …

The Effect Of Success And Failure Experiences On Self Concept In Retarded Children, Candace Joan Varvil

Theses and Dissertations

The object of this study was to examine the relationship, if any, between success and failure experiences and self-concept in retarded children. The Piers-Harris Children's Self-Concept Scale was administered to 30 institutionalized mentally retarded children at the Grafton State School. Following the administration of the pretest, the subjects were divided into three groups, two experimental and one control. Each group was further subdivided into a high and a low self-concept group on the basis of pretest performance. The groups were generally comparable with respect to chronological age and sex. Experimental group A was exposed to a success experience, experimental group …

Development And Characterization Of A Model Latent Herpes Simplex Virus Infection In Cultured Cells, James Varani

Theses and Dissertations

Herpes simplex virus is the classic example of a virus which persists indefinitely in the host following the initial infection. Recurrent episodes of active virus growth characterize the infection in some individuals . In addition to the periodic flair-ups of active virus growth, the persistence of virus may be expressed in a more subtle way. It is possible that one or more types of human cancer result from the persistence of this virus in the host.

The exact mechanism by which the virus is maintained in the host between outbreaks of active growth is not known. It is usually not …

The Relationship Between Attitudes Toward Women's Roles And Field Dependence-Independence In College Students, Patricia A. Torness

Theses and Dissertations

One rather consistent finding from studies involving field dependence-independence is that males are more field independent, more articulated in their approach to certain perceptual tasks, than females. It appears that socialization factors and sex-role identification relate to the development of field dependence or field independence. If society plays a part in the development of individual differences in field dependency, a change in society such as the present movement toward greater equality in sex roles could possibly influence sex differences in field dependency. The present study attempts to assess the effect of attitudes favoring traditional roles for women vs. more liberal …

Kenneth Patchen Picture-Poems, Laurel J. Reuter

Theses and Dissertations

The problem was to present an exhibition of the works of Kenneth Patchen to the University of North Dakota community; to augment the exhibition with a published catalog which would give the uninitiated viewer a sense of Patchen's place in both literature and the visual arts; to accompany the catalog, in thesis form, with a critical article about Patchen’s work.

The procedure involved the following steps: (1) A compilation of a Patchen bibliography. (2) A week in California with Mrs. Patchen during which time I surveyed the artist's entire output of picture-poems and, based upon my critical judgment of the …

Subordinating And Coordinating Particles In Lakhota, Wolfgang Corduan

Theses and Dissertations

In her Dakota Texts Ella Deloria appears to be using cha and chanke interchangeably. The goal of this paper is to show that the difference lies in the realm of subordination. For this purpose other languages have been examined to detect how subordination is marked in them. Both German and English are shown to mark subordinate clauses overtly, but Lakhota markers are not so apparent. Subordination is formally defined in a Generative Semantic framework and pertinent works on Lakhota grammar are reviewed. The solution implied by Boas and Deloria that cha is a subordinator is accepted and proven to be …

Forty-two freshman and sophomore football players at the Univ- \ ersity of Minnesota Technical College - Crookston served as subjects. The subjects were divided into three experimental groups. Experimental Group I participated in football practice and isotonic resistance training, Experimental Group II participated in football practice and isometric resistance training, and Experimental Group III participated in football practice and resistance running …

Activity Of A Dipodomys Ordii Population Using Recapture Methods, James R. Garcia

Theses and Dissertations

Activity curves for Dipodomys ordii were developed from data obtained from a study utilizing an electrically monitored trapping grid. The curves for non-perturbated populations showed an initial post-dusk peak, followed by increasing activity and a large pre-dawn peak; but after ten dominant animals had been removed, the largest activity peak was post-dusk. Differences in activity patterns were not found among sex, age or reproductive classes. Rising ambient temperatures, falling barometric pressures, winds over 3.2 km/hr and the absence of the moon depressed capture numbers; while increasing humidity (relative and absolute), decreasing soil temperatures at 20 and 40 cm below ground …

The Effects Of Highway Construction On The Fish Populations In The Weber River Near Henefer, Summit County, Utah, Edward James Peters

Theses and Dissertations

Alterations of streams to facilitate highway construction and consumptive water use has become a fisheries management problem. To evaluate the effects of channeling concomitant to construction of Interstate 80 N. near Henefer, Utah, altered and unaltered sections of the Weber River were compared on the basis of fishes censused, population estimates and ordinations. Species compositions in particular areas were influenced by local rheologic conditions. Changes in species composition between samplings at a particular area were caused by fish movements. Data from altered sections, rehabilitated with deflectors and checkdams, were not noticeably different than data from unaltered areas. However, fish movements …

The Survival Of Bureaucracy In An Age Of Accelerating Change, Joseph G. Neelon

Theses and Dissertations

The purpose of this study is to examine the question of whether bureaucracy as an organizational form will survive in the age of accelerating technological and social change which is coming into being at this time. By analyzing the strengths and weaknesses of the bureaucratic form of organization, together with the environmental factors which lend it strength, then comparing these factors with present and projected organizational needs and environmental constraints, the conclusion was reached that a modified, more flexible form of bureaucracy will survive into the future. It will be one of several organizational forms, such as matrix organization and …

The Purification And Characterization Of Methylmalonyl Coa Mutase From Bovine Brain, Damon Martin

Theses and Dissertations

Methylmalonyl CoA mutase has been purified over 2300-fold from bovine brain using fractional precipitation, ion exchange resins, and gel filtration procedures. The crude extract had an equal mixture of mutase in the halo- and apoenzyme form. After the final purification step the ratio had changed to 86% holo-enzyme and 14% apoenzyme. The mutase enzyme had a pH optimum of 7. 0 in Tris-HCI buffer. The Km values for L-methylmalonyl CoA and succinyl CoA were 7.7 x 10^-4 M and 1.8 x 10^-4 M respectively. The equiIibrium constant in the direction of succinyl CoA formation was 19. Inhibition with N-ethylmalei-mide was …

The Genus Hedysarum In North America, Terry Edwin Northstrom

Theses and Dissertations

In North America, Hedysarum taxa extend from southern Arizona to Banks Island and from northern Alaska to Newfoundland. They exhibit a high degree of polymorphism which is usually expressed in the form of a gradient in morphological characteristics. Four species, one subspecies and four varieties are recognized, including one new combination, H. boreale ssp. boreale var. rivulare (Williams) Northstrom. Comparative anatomical and morphological studies revealed two basic patterns. Chromosome numbers of all taxa were determined. The basic chromosome number of H. alpinum, H. sulphurescens and H. occidentale is n=7. The basic chromosome number of H. boreale is n=8. Seed protein …

The Population Dynamics Of Tanypus Stellatus Coquillett (Diptera: Chironomidae) In Goshen Bay Of Utah Lake, Dennis Kenji Shiozawa

Theses and Dissertations

The population dynamics of Tanypus stellatus in Goshen Bay of Utah Lake was investigated from July 18, 1973, to August 5, 1974. Samples were collected from three stations with an Ekman grab and a K-B corer. The samples were washed in a 110 micron nitex screen and then floated in a sucrose solution. The K-B core was used to determine the vertical distribution of Tanypus stellatus. Ninety-six percent of the Tanypus stellatus larvae are located in the top five centimeters; 99 percent are less than ten centimeters deep. The Ekman grab was used to study the population dynamics of the …
