Fire Behaviour In Aspen Slash Fuels As Related To The Canadian Fire Weather Index, M.E. Alexander

Aspen Bibliography

The characteristics and short-term results of experimental prescribed fires in 2-year-old trembling aspen (Populus tremuloides Michx.) logging slash in northern Minnesota have been described by D. A. Perala (1974. Can. J. For. Res. 4: 222-228). The associated burning conditions are expressed here in terms of the weather-dependent numerical fuel moisture codes and fire behavior indexes of the Canadian system of forest fire danger rating.

Møller-Plesset Treatment Of Electron Correlation In (Hohoh)-, M. M. Szczesniak, Steve Scheiner

Chemistry and Biochemistry Faculty Publications

The effects of electron correlation on the calculated properties of the (HOHOH)⁻ anion are studied using Møller–Plesset (MP) perturbation theory. With this technique, inclusion of corrections up to third order are shown to provide results quite similar to those obtained with an extensive CI approach when equivalent basis sets are used. Barriers to proton transfer between the two oxygen atoms at a fixed R(OO) distance are computed with a number of basis sets ranging from split‐valence 4–31G to triple‐valence with polarization functions on all atoms, 6–311G∗∗. Each successive enlargement of the basis set leads to a greater barrier. …

Comparison Of Proton Transfers In Cationic Heterodimers And Homodimers Of Nh3 And Oh2, Steve Scheiner

Chemistry and Biochemistry Faculty Publications

Ab initio molecular orbital methods are used to study proton transfers in the cationic heterodimer (H₃NHOH₂)⁺ as well as the symmetric homodimers (H₂OHOH₂)⁺ and (H₃NHNH₃)⁺. All calculations are carried out at the Hartree–Fock level with a 4‐31G basis set to ensure consistency. For proton transfers along a linear hydrogen bond in the heterodimer, asymmetric single‐well potentials with a minimum corresponding to (NH₄)⁺(OH₂) are obtained for R(NO) distances of less than 2.85 …

Biological Engineering Faculty Publications

Bioassay procedures to describe, evaluate, and predict potential hazard of toxic materials to organisms, ecosystems, and health-related aspects of polluted waters continue to receive widespread attention. However, synthesizing these diverse theoretical, methodological, and procedural entities into an integrated multidisciplinary approach to evaluate environ mental hazards of toxic substances remains difficult. Symposia proceedings pertinent to the toxic substances management in ecosystems have appeared¹ and provide an overview of major problems and emerging solutions, including chapters on new bioassay protocols development, and multiple exposure toxicity paradigms. Conclusions and recommendations resulting from a toxicity testing workshop² discussed current state-of-the-art, identified needed …

A Chance-Constrained Programming Model Of Water Allocations In Utah, John E. Keith, Gustavo A. Martinez Gerstl, Rangesan Narayanan, Donald L. Snyder

Reports

A chance-constrained separable programming model of water allocations between agriculture and energy production was developed in order to examine the effect of the variability of water supplies in Utah. Using an incomplete gamma function, based on method of moments estimation of parameters, the water flows at 85, 90, and 95 percent probabilities of occurence were generated. These flows were then used as constraints in the allocation model. Results indicate that water quality could be a more significant constraint on irrigated agriculture than water quantity in the face of large scale energy development, and the variability of water availability alone is …

Nonparametric Analysis Of Right Censored Data With Multiple Comparisons, Hwei-Weng Shih

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

This report demonstrates the use of a computer program written in FORTRAN for the Burroughs B6800 computer at Utah State University to perform Breslow's (1970) generalization of the Kruskal-Wallis test for right censored data. A pairwise multiple comparison procedure using Bonferroni's inequality is also introduced and demonstrated. Comparisons are also made with a parametric F test and the original Kruskal-Wallis test. Application of these techniques to two data sets indicate that there is little difference among the procedures with the F test being slightly more liberal (too many differences) and the Kruskal-Wallis test corrected for ties being slightly more conservative …

Aggregation Behavior Of Aplomyiopsis Xylota (Diptera: Tachinidae), Frank J. Messina

Biology Faculty Publications

The tachinid A. xylota is a common parasitoid of larvae of Trirhabda virgata and T. borealis (Coleoptera: Chrysomelidae) in central New York [USA]. Flies aggregated on herbaceous vegetation along the borders between old fields and more shaded habitats (shrubby fields or woodlots). Aggregations comprised from less than 100 to a few thousand individuals, almost all of which were male. Males continuously perched and moved about in sun flecks on the vegetation and frequently grappled with each other. In the old field adjacent to the primary aggregation site, the tachinid sex ratio was strongly skewed toward females. Aggregations of A. xylota …

A Sourcebook For The Interpretation Of Traditional Dance By Outdoor Museums And Historic Sites, Jan Alm

Library Faculty & Staff Publications

Folklife scholars often produce work which is valuable to outdoor museums and historic sites. Folklife scholars deal with functional, contextual, emic, and interdisciplinary studies--all approaches which produce valuable interpretive data for museums and sites. This thesis is an example of folklife work designed for use in the museum field.

Outdoor museums and historic sites are increasingly involved with the interpretation of social and emotional life. Because it is a social and emotional event, dance can be a valuable part of this interpretation.

Sites and museums developing programs of traditional dance interpretation may find it helpful to follow several steps: 1.) …

Nucleotide Sequence Homology Between Rotaviruses, Jai Myung Yang

Biology

By coelectrophoresis in polyacrylamide gels, bovine, simian, and porcine rotaviruses exhibited different migration patterns in their double stranded RNA genome. There was less variation between bovine and simian rotavirus migration patterns than between bovine and porcine rotavirus patterns. Nucleotide sequence homology determined by hybridization between 3H labeled double stranded RNA and in vitro produced single stranded RNA showed 74 percent homology between bovine and simian rotaviruses, and 8 percent homology between bovine and porcine rotaviruses. The lack of a close relationship between bovine and porcine rotaviruses was confirmed by hybridization between 3H labeled, in vitro produced, single stranded RNA and …

The purpose of this study was to measure the academic performance of children with mild hearing loss (20-45 dB) by comparing them with a normal control group. Twenty-four pairs of children in the first through fourth grades were compared. The achievement scores of the second and fourth grade student pairs were compared for the current academic year and for the previous academic year. A two-way analysis of Variance was used to compare the achievement scores from the Iowa Test of Basic Skills of the two groups. The results indicated statistical significance on some subtests of the first and fourth grade …

Marital Roles And Their Relationship To Marital Happiness And Self Concept, Gary L. Devries

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Marital roles have become a subject of major concern in recent years. Many critiques consider traditional marriage roles to be responsible for hindering appropriate social-emotional development of the wife, in particular, and also the husband. Past research in assessing the relationship between marital roles and the happiness and well-being of husbands and wives is limited in quantity and generally is inconclusive or controversial. This study was designed to clarify the relationship between marriage roles and two dependent variables, marital happiness and self concept.

The sample population consisted of 124 volunteer couples selected from the teaching staffs of eight school districts …

Diagnostic Considerations In The Identification Of The Hyperactive Child, Barbara Jagoda Draheim

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

The hyperactive disorder of childhood and the enumeration of its features were described in two papers published in the mid-1950's, by Laufer and his colleagues (Laufer, 1957; Laufer, Denhoff & Solomons, 1956). It was a list that has since become familiar; short attention span, impulsivity, irritability, low frustration tolerance, poor academic achievement, and visual-motor difficulties. Like many who have since searched for definers of the syndrome, Laufer and his colleagues remarked upon the perplexing variability displayed by these children, and they noted that no single symptom could be considered diagnostic. They described the development of "secondary psychological difficulties" due to …

Ego Strengthening Hypnotic Suggestions Versus Specific Hypnotic Suggestions In The Treatment Of Obesity, Richard A. Hutchison

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A comparison was made of two types of hypnotic suggestions. Twenty seven subjects in two groups participated in eight weekly one-hour group hypnotic sessions. All subjects were given the Minnesota Multiphasic Personality Inventory, the Tennessee Self-Concept Scale, and were weighed pre, post and at four month follow-up. Both types of hypnotic suggestions were equally effective in helping individuals lose weight. The average weight loss was 10 pounds at follow up. Both groups showed improvement on the personality tests. Those who received the ego-strengthening hypnotic suggestions showed more improvement and more long lasting improvement than did those who received the specific …

The Energy Expenditure Of Heifers Grazing Crested Wheatgrass Rangeland In West-Central Utah, Kris M. Havstad

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The free-roaming ruminant requires energy for the demands of vii grazing, traveling and thermoregulation that are not required by its confined counterpart. Literature estimates of these additional costs range from 10 to 170 percent above maintenance. The uncertain magnitude of this increased demand and the factors that contribute to it impede the ability of the rangeland ruminant nutritionist to establish guidelines for the energy requirements of the free-roaming herbivore. This study was designed to estimate the energy expenditure of yearling Angus heifers while grazing a declining supply of available crested wheatgrass forage (Agropyron cristatum) on rangeland in west-central …

During the last three decades, there has been a significant growth in the outdoor recreation industry. In 1969, there were 17.6 million visits to national parks, and by 1978, that number had increased to 283.1 million (Gregory, 1972; U.S. Dept. of Commerce, 1979). Similarly, visits to national forests grew from 5 million in 1925 to over 147 million in 1965 (Clawson and Knetsch, 1966).

Simulated Use Of The Exponential Polynomial/Maximum Likelihood Technique In Developing Suitability Of Use Functions For Fish Habitat, Kenneth A. Voos

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this paper is to present a new methodology for producing fish habitat suitability at use functions. The suitability functions are relative measures of the voluntary or involuntary preference for combinations of the values of environmental attributes by a fish species and age class. This suitability function is used to determine the relative usability of a physical stream environment as fish habitat.

A generalized function form, exponential polynomials, was selected for the development of these suitability of use functions. The maximum likelihood technique was used for function parameter solution. Derivation of the suitability functions was simulated for several …

The Emergence Of An Afro-American Society In Colonial Amelia County Virginia, Carol Noble Funk

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The eighteenth century is a critical time in a study of American slavery. The colonial years witnessed the development of cultural, social and demographic processes affecting African and Afro-American slaves, the result of which was an Afro-American culture and society, unique to this nation. The slave family and kin network system of the antebellum south and the post Civil War era had its genesis in the decades preceeding the Revolutionary War.

There have been many studies done on slavery in colonial Virginia, but with few exceptions they have focused on the wealthy planters residing in the tidewater counties. They describe …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was undertaken to add to the knowledge of the psychosocial effects of the 4-H program upon its members. The objectives were to determine if 4-H involvement is associated with the psychological and social maturation of adolescent members, and to investigate how several variables such as age, urban/rural residence, and S. E. S. may help explain this relationship or lack of relationship.

To accomplish these objectives 165 youths (103 4-H, 62 non 4-H) and one parent of each youth, responded to mail-out questionnaires, answering questions of biographical content, and items from the Psychosocial Maturity inventory. Responses were compiled and …

Temperamental Characteristics Of Sociometrically Identified Preschool Children, Melinda M. Toney

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This research investigates the relationship between temperament and sociometric status utilizing a sociometric picture technique and the Parent Temperament Questionnaire for Children 3-7 Years of Age, a measurement instrument from the New York Longitudinal Study. The study population consists of sixty-one preschool age children. In the final stage a discriminant function analysis was employed to determine if there was a relationship between the measures of temperament and sociometric status. Although no significant functions emerged, two functions approached significance. The results indicate that popular and amiable children score higher on adaptability and approachability than isolated and rejected children. Also, distractibility appeared …

On Being Human: The Folklore Of Mormon Missionaries, William A. Wilson

Faculty Honor Lectures

Not long ago I was asked to entertain some of my colleagues at a faculty gathering by telling stories about J . Golden Kimball, that crusty old Mormon divine who salted his sermons and public statements with a liberal sprinkling of cuss words and earthy metaphors. Because I know a fair number of these stories and enjoy telling them, I agreed. The event was a tolerable success. At least most people laughed, and no one threw brickbats. Still, as I drove home, I wondered if I had not done more harm than good. I had, I feared, simply strengthened the …

Theory And Intuition, E. A. Mccullough Jr.

Faculty Honor Lectures

Among the practitioners of science are people who are called theorists , and this lecture is concerned with the question, Just what is it that a theorist does?

If an experimentalist does experiments, then a theorist presumably does theories. What is a theory? My dictionary defines it as ". . . a system of assumptions, accepted principles, or rules of pro· cedure devised to analyze, predict or otherwise explain the nature or behavior of a specified set of phenomena."

Those who now understand perfectly what a theorist does may stop reading here because everything that follows will be superfluous. For …

Elevated Electron Temperatures In The Auroral E Layer Measured With The Chatanika Radar, Vincent B. Wickwar, C. Lathuillere, W. Kofman, G. Lejeune

All Physics Faculty Publications

An extensive series of spectral measurements has been made in the auroral E region with the Chatanika incoherent scatter radar. Becasue of the small scale length for variations of electron density, temperatures, and ion-neutral collisions we used the operating mode with the best possible range resolution—9 km. About 5% of the time the data exhibited an unusual spectral shape that was most pronounced at 105 and 110 km. Instead of being almost Gaussian with only a small hint of two peaks, the spectra are much wider, with two well-developed peaks. After carefully considering the validity of the measurements and their …

Energization Of Ionospheric Ions By Electrostatic Hydrogen Cyclotron Waves, Nagendra Singh, Robert W. Schunk, Jan Josef Sojka

All Physics Faculty Publications

Interactions between ionospheric ions and a monochromatic electrostatic hydrogen cyclotron wave were studied numerically for conditions corresponding to the auroral plasma. Strong heating of the minority ions He⁺, He⁺⁺, and O⁺ were observed. The fraction of the initial ion population which underwent heating was found to strongly depend on the mass, charge, and initial temperature of the ion species.
