Kinetic Analysis Of The Ion Exchange Of Sodium From Subbituminous Coal, Jason Allen Chesley

Theses and Dissertations

The removal of Na from subbituminous coal by ion ex change was investigated on a batch basis with H-ion donated by dilute aqueous The exchange of K, Mg, Ca, and A1 from the coal was also observed. The four parameters stud ied were initial H2SC>4 concentration, coal particle size, residence time, and liquid to solid mass ratio.

Results from this investigation indicate that at equi librium 95 % of the initial Na content of the subbituminous coal can be removed by ion exchange with dilute aqueous H2S04 . It was also determined that Na removal is directly proportional to …

Hemispheric Laterality And Cognitive Style, Christine J. Kuchler

Theses and Dissertations

The purpose of the present study was to determine the nature and degree of relationship between cerebral "hemispheric style" and several traditional dimensions of "cognitive style." A large battery of laterality preference, cognitive style, verbal and nonverbal ability, and selected additional tests was administered to 97 (52 female, 45 male) right-handed undergraduate volunteers, with subsequent analysis of relationships among the measures by simple correlation, factor analysis, and multiple regression methods.

Laterality measures included the Zenhausern, Verbalizer-Visualizer Questionnaire, and a lateral eye movement observation measure. Data analyses utilized individual laterality test scores as well as a composite "laterality index." Eleven cognitive …

Values And Academic Achievement Among Rural Indian High School Students In North Dakota, Janet Lee Clark

Theses and Dissertations

Literature relating to American Indian formal education reveals that throughout much of history, the majority culture has stressed assimilation in the educational process. Indian students have been encouraged to give up their values and embrace the values of majority culture members. However, for the majority of Indian people, the goals of assimilation have not been realized. Indians have retained unique cultural values.

This study was designed to systematically investigate the role of differential values in the educational process of rural North Dakota Indian high school students. High school students and their teachers from seven schools were surveyed in group testing …

Development Of A Computer-Aided Analysis Package For Linear Elastic Fracture Mechanics, William E. Warkentin

Theses and Dissertations

This thesis develops an interactive computer-aided analysis package for solving linear elastic fracture mechanics problems. CHILES 2 (an existing finite element fracture mechanics program) was modified to be interactive. The modified program is named CHILES.BYU and is used in conjunction with QMESH.BYU and MOVIE.BYU to form the total software package. An analysis of glass ceramics and glass ceramic/metal interfaces was performed demonstrating the capabilities of the package. This study demonstrates the usefulness of an interactive package of computer programs to allow an engineer to rapidly investigate different crack configurations.

A Nutritional And Morphological Study Of Two Cyanobacteria Free Azolla Ferns, Michael Paul Bonner

Theses and Dissertations

The symbiotic association between the aquatic water fern Azolla and its symbiont, Anabaena azollae Straus. has been extensively studied in the past ten years. The cyanobacteria has received much of the attention due to its ability to fix atmospheric nitrogen while the fern free of the cyanobiont has been somewhat neglected. The purpose of this research was to determine the nutritional requirements of the cyanobacteria free (CBF) ferns and study the morphology of the leaves and branches of these CBF ferns.

Azolla filiculoides and Azolla pinnata were freed of the cyanobiont using the surface sterilization technique adopted from Duckett, et …

Poe Per Se, Robert Williamson Storrs Iv

Theses and Dissertations

There are four elements involved in this production of Poe per se which make it interesting and suitable as a thesis: the actor, the subject, the format, and the audience. I will discuss the problems posed by each and the methods of attack I will pursue to those problems. I will then describe the evolution of the script from research through performance. My conclusion will be an assessment of the success of the script in solving my acting problems.

Verging Gardens, Jeffrey Ruggles

Theses and Dissertations

Webster's gives as an archaic meaning for the verb design "to indicate with a distinctive mark, sign, or name." For the kind of photograph which is essentially taken, not made, the idea of indicating is more appropriate than concepts of building up from a blank sheet of paper. The correct exclamation when this photographer thinks a success has been completed is "Eureka!": "I have found it!"

This paper identifies the topographic landscape as a type of photographic practice, examines the characteristics of the topographic landscape, and traces its development. The concepts of "density" and "the garden" in the topographic landscape …

Characterization Of Selectively Modified Chymotrypsins And Their Specificity Towards Dipeptide Substrates., Nat Jorn Suwarnasarn

Theses and Dissertations

The 15 surface carboxyl groups in alpha-chymotrypsin first were modified with glycine ethyl ester (Gly-OEt) and taurine (Tau) at pH 4 using carbodiimide (EDC) reagent to give G(,15)-Chy and T(,15)-Chy, respectively. These enzymes (Chy-15) were remodified using norleucine methyl ester (Nle-OMe) as a tag in the presence of 8M urea. The analytical determination of the Nle-OMe tag was done by amino acid analysis and showed 1.5 and 2 moles of Nle per mole of T(,15)-Chy and G(,15)-Chy, respectively. Initial modification of alpha-chymotrypsin in the presence of 3M urea using Tau and Gly-OEt show 15.8 and 16 moles of Tau and …

The Influence Of Children's Art On Joan Miró And Jean Dubuffet, Linda L. Ferrell

Theses and Dissertations

Children's art has been acknowledged as an important influence on twentieth-century art. Robert Goldwater states that the interest among artists in children's art during the early years of the Twentieth Century marked "a movement away from the exotic primitive toward indigenous sources of primitive inspiration." This new evaluation of children's art as a source of inspiration can be seen in the work of a number of artists including Joan Miró and Jean Dubuffet; their work, in particular, suggests the accent, freshness and energy inherent in the art of children.

The child’s way of making art, which is not based on …

Interactions Between Murine Peritoneal Macrophages And Naegleria Fowleri, Leigh Ann Belcher

Theses and Dissertations

In the present study, we have examined the differences among Corynebacterium parvum-activated, thioglycollate-elicited, and resident macrophages from (C57BL/6 X C3H)F1 mice utilizing two microcytotoxicity assays. Macrophage and Naegleria fowleri were interchangeably employed as effector and target cells. To assess the ability of the macrophage to lyse N. fowleri, the amoebae were labeled with 5 μCi of 3H-uridine per 5 x 10^5 cells for 18 h prior to co-culturing with adherent macrophage monolayers. Although the macrophage-induced lysis was density and time dependent, C. parvum macrophages consistently demonstrated an increased cytotoxic response to N. fowleri after 24 h co-incubation at a 10:1 …
