Effect Of Rain Leaching On Chemical Composition Of Alfalfa Hay, Mercedes M. Garcia De Hernandez

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Yield and chemical changes of second-cutting alfalfa hay treated with artificial rain were determined in a 2 x 3 x 2 factorial experiment. Factors were 2 stages of maturity (1 = late vegetative; 2 = early bloom), 3 levels of artificial rain applied (1 = no rain; 2 =low or approximately 5 mm; 3 = high or approximately 20 mm), and 2 times of applying artificial rain (1 = when drying forage was 40-60% dry matter; 2 = when drying forage was 60-75% dry matter). Thirty samples of alfalfa were collected at the 2 stages of maturity when the alfalfa …

Location Value Of Milk, Martin K. Beutler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Due to the growth of milk marketing areas in the Intermountain West, a study was made to determine the most advantageous allocation of producer milk to twelve selected processing demand areas and to calculate location differentials between these same markets. A theoretical determination of location differentials and of the allocation of milk supply areas to processing centers were made using supply-push and demand-pull price alignment models developed by Associated Milk Producers, Inc., for the months of November 1979 and June 1980. Grade A producer mil k from the six member cooperatives of Western Dairymen' s Cooperative, Inc., was used in …

Methodology used was a farm budget analysis of a before development and after development situation. Internal rate of return and benefit/cost ratio were the measures used to determine economic feasibility. The paper discusses previous work completed, the development …

Influence Of Lipophilicity On The Accumulation And Distribution Of Halogenated Phenols And A Pyridinol As Metabolites Of Pesticides In The Rat, Assed A. Attumi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Exposure to halogenated phenols and pyridinols is of increasing concern because of their wide use and distribution. This research was initiated to determine the distribution, accumulation, and depletion of a group of halogenated phenols and a pyridinol in selected tissues of male weanling rats at different time intervals following a single oral dose of 0.33 or 1.66 m moles per kg body weight. The halogenated phenols and pyridinol were distributed differently in every tissue sampled following their administration, even though the amount administered was the same in each case. The concentrations in tissue were found in the order: 2,4,5-trichlorophenol > 4-bromo-2,5-dichlorophenol …

Stream Insect Production As A Function Of Alkalinity And Detritus Processing, Thomas G. Osborn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The study was conducted to determine if aquatic insect production was significantly different between high and low alkalinity mountain streams and if any differences were associated with food availability factors. The major objectives included determining: (1) if annual production differences occur between high and low alkalinity streams; (2) if processing rates of terrestrial detritus differs between high and low alkalinity streams; (3) if detrital processing rates are related to stream insect productivities; (4) if primary productivity varies between high and low alkalinity streams; (5) if toxic effects or micronutrient limitations exist in high or low alkalinity streams that could limit …

The Effects Of The Childbirth Process On The Attitudes And Behaviors Of New Fathers, Janice Ryser

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Attitudes of 74 first-time fathers were studied as they varied vi by childbirth preparation and participation. A 50-variable questionnaire was used to tap fathers' attitudes towards their marital relationship and partner, their infants, themselves as fathers, and the pregnancy/childbirth experience.

Fathers agreed on being elated with fatherhood, wanting tactile, verbal, and extended home contact with their infants, planning on a partnership in parenting, and seeing their marriage at a high point. They saw pregnancy as a time of stress and adjustment and felt father participation was important. Their attitudes varied most on wife's performance and their own helpfulness through labor …

Faunal Succession And Depositional Environments Within The Lodgepole Limestone (Early Mississippian) Of Samaria Mountain, Idaho, Gary Keith Hines

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Community succession, the orderly changes a community experiences with time, is considered to be the result of either autogenic or allogenic factors working singularly or in combination. It has been further suggested that, as communities undergo succession, certain biological parameters change in a predictable manner. Examination of members 2 through 4 of the Mississippian (Kinderhook-Osage) Lodgepole Formation of Samaria Mountain, Idaho provides a means to evaluate these concepts.

Within the study section comprised of 125 beds (61.5 m thick), four rock types are recognized. These include: (1) fossiliferous wackestone (78% of beds), which ranges in color from dark-gray (N3) to …

Autoshaping Infant Vocalizations, Alexander Mcnaughton Myers

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A series of five experiments was conducted to determine whether operant or respondent factors controlled the emission of a particular vocalization ("Q") by human infants 16 to 18 months old. Experiment 1 consisted of a pilot investigation of the effects of an autoshaping procedure on three infants' vocal behavior. All three subjects demonstrated increased emission of the target sound during the CR period. Experiments 2 through 4 attempted to replicate the findings of Experiment 1 under controlled conditions, and failed to do so. Experiment 5a presented infant subjects with a discrete-trial operant procedure (having the identical temporal parameters as the …

An Enzyme-Linked Immunosorbent Assay (Elisa) For Pantothenate, Allen H. Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An enzyme-linked immunosorbent assay (ELISA) for pantothenate has been developed. Antibodies induced in rabbits against bovine serum albumin-pantothenate conjugate were specifically purified by affinity chromatography. This process served to reduce the amount of endogenous pantothenate attached to the antibody, as well as to purify the antibody. The purified antibodies were covalently linked to alkaline phosphatase (Sigma type VII) with glutaraldehyde (0.05% aqueous solution). An immobilized pantothenate substrate was first obtained by attaching human serum albumin-pantothenate conjugate to the surface of polystyrene culture tubes by passive adsorption. The binding of the enzyme labelled antibody (E-AB) to this substrate is proportionately inhibited …

Mechanism Of Two Homogeneous Reactions; Co Self Exchange And N2 Self Exchange, Alan L. Rockwood

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The two atom switching reactions referred to in the title were originally studied at temperatures greater than 2000°K in shock tubes by other investigators. For each reaction they proposed a direct four-center exchange mechanism in which one of the reactant molecules must be vibrationally excited, (the vibrational excitation mechanism or VEM). One of the predictions of the VEM is that molecules which are vibrationally hot but translationally cold should react through the four center transition state that leads to exchange.

Using a mercury photosensitization technique, it is shown in the present work that excitation of CO to high vibrational levels …

The Effects Of Psychodiagnostic Information And Therapist Accountability On Psychotherapeutic Outcome, Alan Leonard Zohner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to determine the effects of psychodiagnostic information provided by the Symptom Checklist-90-Revised (SCL-90-R) and the Hopkins Psychiatric Rating Scale (HPRS), and therapist accountability on the psychotherapeutic outcome measures of goal attainment scaling (GAS), number of client-therapist sessions, length of treatment, therapist ratings of client improvement, and type and frequency of client termination. The subjects of this study were 72 persons who sought services at Bear River Community Mental Health Center, Logan, Utah, and who, subsequently, were assigned to one of eight participating therapists at this center. These clients were divided into three treatment groups …

Examination Of The Effect Of Physical Exercise On Metabolic Control In Type I Insulin-Dependent Youth With Diabetes Mellitus, Gayle Ann Brazzi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

There is evidence for the importance of physical exercise balanced with diet and insulin therapy in the treatment and control of Type I insulin-dependent diabetes mellitus. Recent attention in the literature has focused on the once neglected component of treatment--exercise. A well-controlled exercise state is generally believed to be beneficial for the individual with diabetes. Limited studies are available on the effect of exercise on long-term metabolic control. Before exercise levels can be professionally prescribed for a given population of youth with diabetes, current exercise patterns should be evaluated as to the effect on long-term metabolic control.

It is the …

Metaphorical Interpretations Of The Neurotic Paradox, Mark J. Weaver

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This is a theoretical/philosophical paper which is intended to bring to the reader's attention an emerging literature and discussion which holds potentially productive consequences for the understanding of man. This thesis does not offer completed formulations or empirical groundings. The purpose is to create a basis for dialogue.

This paper will initially specify a current conflict in psychology around the different metaphors used to define the image of man. A theoretical/philosophical basis for viewing the process of generating models of man and his behavior as essentially "metaphorical" is then presented. A specific category of human behavior known as the neurotic …

The Effectiveness Of Electronic Games (Atari) Reinforcers For Increasing Appropriate Behavior In Handicapped Children, James M. Payant

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ten subjects ranging from 9 to 16 years in age with IQ's ranging from 23 to 62 were randomly selected as contingent or noncontingent subjects for two experiments. Five subjects received contingent access to two electronic games for performance within a specified learning session, while five subjects received noncontingent access to the games. These experiments were designed to determine the effect on performance, attending, and compliance skills in the classroom, when contingent access to the electronic games was based on performance. The development of fine motor skills and/or eye-hand coordination skills as a result of game usage was examined. The …

The Effect Of Item Format On Computation Subtest Scores Of Standardized Mathematics Achievement Tests, Larry Carcelli

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effect on childrens' scores of different item formats used in standardized mathematics achievement tests was investigated. Second grade students were given a mathematics computation test using formats derived from five standardized achievement tests. Identical content was tested with each format. Differences in test scores between types of formats were statistically significant at p < .001 (F = 45.25). These results indicate that what a student appears to know is substantially influenced by the format of the particular test used in measuring achievement. These differences are not accounted for by the normative scaling of the different tests. Greater attention should be given to the effect of test item format in selecting and administering achievement tests.

Cause And Perceived Seriousness Of Deviant Behavior And Attribution Of Responsibility, Mary Kathryn Morris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to investigate the relationship between differing stated causes of deviant behavior which is commonly labelled mental illness, and the perceived seriousness of these behaviors in determining judgments of the degree of responsibility attributed to described deviant individuals. This was accomplished by having subjects rate four different vignettes as to degree of perceived seriousness and degree of responsibility for behavior.

The subjects were 76 undergraduate students enrolled in either introductory psychology and/or introductory anthropology. The subjects were divided into four groups. Each group of 19 subjects received the same four vignettes. Each vignette gave a …

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 …

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 …

A Theoretical Study Of The High-Latitude Winter F Region At Solar Minimum For Low Magnetic Activity, Jan Josef Sojka, W. J. Raitt, Robert W. Schunk

All Physics Faculty Publications

We combined a simple plasma convection model with an ionospheric-atmospheric composition model in order to study the high-latitude winter F region at solar minimum for low magnetic activity. Our numerical study produced time dependent, three-dimensional ion density distributions for the ions NO+, O2 +, N2 +, O+, N+, and He+. We covered the high-latitude ionosphere above 54°N magnetic latitude and at altitudes between 160 and 800 km for a time period of one complete day. The main result we obtained was that high-latitude ionospheric features, such as the ‘main trough,’ the ‘ionization hole,’ the ‘tongue of ionization,’ the ‘aurorally produced …

An Intense Wave/Particle Event In The Auroral Ionosphere, A. D. Johnstone, Jan Josef Sojka, W. Gibbons, B. K. Madahar, L.J. C. Woolliscroft

All Physics Faculty Publications

An intense burst of VLF waves, at frequencies just above the local proton gyrofrequency, was observed shortly after each of two intense bursts of field‐aligned suprathermal electrons (E < 250eV) by instruments carried on a sounding rocket flown in diffuse aurora. If the two phenomena are associated with each other, the implication is that the electron acceleration occurred nearby, in a relatively small volume.

Auroral Plasma Lines: A First Comparison Of Theory And Experiment, E. S. Oran, Vincent B. Wickwar, W. Kofman, A. Newman

All Physics Faculty Publications

In this preliminary report on low-energy (0.3 to 3 eV) secondary electrons in the auroral E layer (90 to 150 km), we compare intensities of plasma lines observed with the Chatanika radar to theoretical predictions obtained from a detailed numerical model. The model calculations are initiated with a flux of energetic auroral primary electrons which enter the atmosphere and lose energy to electrons, ions, and neutrals through a combination of elastic and inelastic collisions. This flux is chosen in order that the total calculated ionization rate matches one that is deduced from the radar measurements. From these same calculations the …

The Bureau of Land Management (BLM) proposes to implement a grazing management program on 1,162,000 acres of public land in Bingham, Blaine, Bonneville, Butte and Power counties in eastern Idaho.  This statement analyzes the economic, social and environmental effects of the proposed action and four alternatives.  The proposal and alternatives analyze different levels of vegetative allocations to wildlife, livestock and other uses.  It analyzes alternative methods by which livestock grazing would be managed as well as necessary support facilities (such as, water developments, fencing, brush control and revegetation projects).  Alternative Four of the Big Desert grazing statement is selected as …

A Laboratory Evaluation Of Leachate From The Jim Bridger Power Plant Scrubber Wastes, V. Dean Adams, Mary E. Pitts, Megan J. Dyer

Reports

Introduction: Scrubber wastes obtained in an affort to limit air pollution generated by coal-fired pwoer plants may contribute to another possible sources of pollution. To date, scrubber wastse have been in a liquid phase which causes disposal problems partially due to the liquid characteristics. The use of solid scrubber wastes and the land deposition of such wastes is proposed. The feasibility of solid scrubber wastes disposal in landfills is under question. The primary area of concern is the effect that water percolation through such wastes would have on groundwater quality parameters. Contamination could result either as precipitation travels downward through …

Tunable Optical Filter Using An Interferometer For Selective Modulation, Roy W. Esplin, Ronald J. Huppi, Marshall H. Bruce, George A. Vanasse

Space Dynamics Laboratory Publications

Using the selective modulation interferometric spectrometer (SIMS) as a tunable filter is proposed. This tunable filter can have a large optical throughput and a resolving power on the order of a few thousand. A basic explanation of the operation of this filter is given with an emphasis on the similarities and differences between it and a Fourier spectrometer. Several equations that have been found to be particularly useful in designing, operating, and calibrating this filter are presented. The construction and operation of a tunable filter prototype are reported.
