The Effect Of Urea On The Sedimentation Coefficient Of The Curly Top Virus Dimer, Allen H. Smith

Undergraduate Honors Capstone Projects

The purpose of this project is to investigate the effect of increasing concentrations of urea on the sedimentation rate of the curly top virus dimer as measured by ultracentrifugation techniques. In general, urea causes the breaking of hydrogen bonds in macromolecules--in the case of the virus, increased concentrations of urea should cause changes in the configuration of the virus and may possibly cause a separation of the dimer into monomers. From previous centrifugation studies, we know that the dimer has a characteristic sedimentation coefficient(S) of about 80 Svedbergs; the monomer has an S value of about 55 Svedberg units. Increased …

English-Vietnamese Translation: An Internship, Blaine L. Hart

Undergraduate Honors Capstone Projects

The art of translation lies in a literary limbo, subservient to the creativity and expressions of others. Yet in attempting to bridge two different languages and cultures, it entails unique problems as difficult as those encountered in any other literary activity.

The following is the report of a project carried out with the Translation Department of the Church of Jesus Christ of Latter-Day Saints in the fall of 1975 as a senior Honors project in fulfillment of requirements for graduation from the Honors Program at U.S.U. Since this internship itself formed the bulk of my project, the following is presented …

Recent Reforms In Campaign Finance Regulations And Their Potential Effect On Federal Elections And Reflections On Washington As A Congressional Intern, Randy D. Funk

Undergraduate Honors Capstone Projects

In the spring of 1975, upon learning that I had been selected as a summer intern in Congressman Gunn McKay's office, I thought that such an experience might readily serve as the basis for my senior Honors project. I discussed this possibility with Dr. Douglas Alder, the Honors Program Director, and Dr. Wendell Anderson, the intern advisor. With their approval, I decided to write one paper on my impressions of Washington as an intern and then upon my return to school, research and write another paper on an issue related to Congress. This is the reason my thesis project is …

Iron Dynamics In A Gas-Water-Sediment Microcosm, Peter A. Cowan, V. Dean Adams, Donald B. Porcella

Reports

Iron dynamics in eutrophic systems were studied in the laboratory utilizing gas-water-Sediment phase sealed microcosms. Sediments from Hyrum Reservoir (2.4 percent iron by weight) were placed in the dark to simulate the hypolimnetic regions of a eutrophic impoundment. Iron both chemically and physically was readily available to microorganisms of the aqueous phase because iron in these systems was soluble. In the light microcosms, which simulated shallow littoral regions of eutrophic impoundments, iron was found in higher aqueous phase concentrations than was predicted chemically and physically; this was rationalized through biological mechanisms. The experiment was conducted in two phases: Phase I …

Moving Toward Effective Teacher Education-One Man's Perspective, Walter R. Borg

Faculty Honor Lectures

It was nine years ago that I decided to leave Utah State University and join one of the newly formed regional educational laboratories. At that time I had 18 years of educational research behind me, and although I had carried out a number of studies and published about 40 articles in the professional research journals, it was obvious to me that none of my research had had any measurable effect upon education. At best, my work might have influenced the decisions of a few school administrators, but this is an optimistic view since most school administrators prefer not to be …

Partial Characterization Of The Genome Of Neonatal Calf Diarrhea Virus (Reoviruslike Agent), Bill B. Barnett

Biology

Electron microscopy, isopycnic centrifugation, thermal denaturation profiles and polyacrylamide gel electrophoresis were used to characterize the nucleic acid from neonatal calf diarrhea virus.

The Development Of Selected Vocalizations Of The Black-Capped Chickadee, Vivian Telford Anderson

Biology

The development of the contact-flight, fright and chickadee-dee calls and song of 20 Black-capped Chickadees, Parus atricapillus, reared in various degrees of social and acoustic isolation was described. A previous study (Anderson, 1970) demonstrated that these vocalizations develop normally in captive-reared Black-capped Chickadees housed with conspecific adults. The present study demonstrated that the contact-flight and fright calls developed normally in birds reared in all forms of isolation. Only the rearing of birds permanently in acoustic isolation cabinets curtailed the development of chickadee-dee calls that fell within the range found in wild populations. Individuals not exposed to conspecific adults …

The Development Of A Proposed Model Office Stimulation For Implementation At The College Of Eastern Utah, Faye Ladawn Torgerson

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

A review of recent articles indicates that the effectiveness of simulation on Vocational Education has been substantiated. Many programs have been used throughout the United States which point out the success of office simulation.

Utah began simulation by converting trailers into mobile modern offices. The first class was taught in June, 1968, with a migrant farm worker project. The program was called MOE (Mobile Office Education). Hanson and Stocker were involved in the development and teaching of this program. They explain their ideas about a successful and effective simulation program:

It is a real organization of students formed under the …

1. History Of The Development Of The Violin 2. Construction Of The Violin 3. Repairs Of The Violin String Instruments, Carl David Nyman

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The origin of all stringed instruments is lost in the midst of time, and despite the most patient and laborious research on the part of famous savants, no positive information has as yet been furnished regarding this point . Knowledge of the subject is more or less conjectural, and all that has been definitely established is the existence of the predecessors of the violin - the English crewth, a six stringed bowed instrument which is conspicuous for its rectangular shape, which is strongly reminiscent of the Greek kithara; the rebec, an instrument in the shape of an elongated pear having …

Reading Abilities Of Third Grade Children As Influenced By Kindergarten Instruction, Diane Thomas

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Literature indicates that in past years a controversy has arisen as to the proper time and methods to begin the instruction of reading to young children. Most recent research indicates that authorities do not advocate formalized instruction by which whole classes or groups of children participate in a given program. However, recent literature also indicates a trend toward structured and formalized reading by public school teaching staff.

While there is a great deal of research in the area of early reading, the research is not definitive. Consequently, a need remains for definitive research that can help in answering questions about …

Comparisons Of Draw-A-Child Test Among Preschool Children, Margaret Prather Ezell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

McCarthy's Draw-A-Child test was administered to 20 lower class and 20 middle class four-year-old children matched for age and sex. The purpose of the test was to find if socioeconomic class and sex differences effected the child's ability to draw a same sex figure. Analysis of results supported the theory that girls do better than boys. Analysis of socioeconomic differences suggests that lower-class children do not have the ability to draw as well as middle class children but the difference is not significant at the .05 level. It was concluded that the McCarthy Draw-A-Child test measures the general drawing abilities …
