A Study Concerning Sources Of Information And Knowledge About Fluoride In Logan, Milford, And Helper, Utah, Marilyn Lorraine Geddes

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A considerable amount of research has been conducted concerning the characteristics of people who are in favor of fluoridation. However, there is little information available as to what the electorate really knows about fluoride when they are forced to vote on this scientific issue.

Thus, the objectives of this study were to determine the general public's level of knowledge about fluoride, to discover what sources of information have been the greatest influence on their opinion and knowledge about fluoride, and to estimate the level of participation of dentists, general practitioners, pediatricians, and gynecologists in the education of Utahns about the …

A Comparison Of Selected Isokinetic Training Velocities On The Development Of Muscular Power In College Women, Julia P. Knight

Human Movement Studies & Special Education Theses & Dissertations

The purpose of this study was to compare the effects of three different isokinetic velocities on the development of muscular power. Seventy-five college females were matched into four equal groups according to the average of their pre-test scores on the Vertical Power Jump Test and the Power Staircase Test. Group I served as the control group, while all 3 of the experimental groups performed the same isokinetic exercise at different pre-set rates of speed. Groups II, III and IV worked at the selected rates of .8, 2.3 and 3.9 inches per second respectively. All four groups were pre-tested and post-tested …

Social Play And Play-Soliciting By Infant Canids, Marc Bekoff

Ethology Collection

The development of social interaction was studied in infant coyotes, beagles, and wolves. In this paper, social play behavior is discussed. Social play may be characterized in a number of ways: (i) actions from various contexts are incorporated into labile (unpredictable) temporal sequences; (ii) the "play bout" is typically preceded by a metacommunicative signal which indicates "what follows is play"; these signals are also observed during the bout; (iii) certain actions may be repeated and performed in an exaggerated manner; (iv) the activity appears "pleasurable" to the players.

By comparing these three species, some insight into the dynamics of social …

Recollections, George W. Beadle

Department of Biochemistry: Faculty Publications

In these exciting times when elementary and high schools teach modern biology, including many of the intricacies of biochemical genetics, the long slow process by which our present knowledge in this area was gained is not often fully appreciated. A third of a century elapsed before Mendel’s work was "rediscovered" and properly appreciated. Archibald E. Garrod’s (1) prophetic appreciation of the relation genetics and biochemistry, beginning soon after the so-called rediscovery of Mendel, lay fallow for more than forty years despite the fact that he published widely and relatively voluminously. As late as a quarter of a century after the …

A Method Of Detecting Reaction To Environmental Influence By Recording Circadian Activity, Using The Flagfish Jordanella Floridae, Robert Matsuo Kano

University of the Pacific Theses and Dissertations

This paper investigates a means of detecting the reaction of aquatic vertebrates to environmental change by recording behavioral patterns within the diurnal activity. An apparatus measuring the activity of Jordanella floridae, Goode and Bean, using a photoelectric sensor system is described. Individual sensors monitored specific areas of the test aquarium that had special significance to the fish in the way of a particular behavioral category. An event recorder documented the breakage of light beams, giving continuous and accurately timed data of activity. Two distinct patterns of activity were recognized; a control, or typical, pattern, and a pattern resulting from the …

The Study Of The Transfer Of Learning Between Fine And Gross Motor Skill After Practice On Similar Mirror Reversal Tasks, Roberta A. Klugman

Dissertations and Theses @ UNI

The purpose of this study was to investigate the transfer of learning between fine and gross motor skill after practice on similar mirror reversal tasks. Transfer of learning would seem to imply that the learning of either type of skill, fine or gross, may facilitate the learning of the other. This study utilized a quasi-experimental, pre-post, three group design, Subjects were male and female volunteers from junior and senior high schools in Cedar Falls, Iowa. Sixty subjects were used in the analysis of the data with twenty-one in each experimental group and eighteen in the control group. Analysis of covariance …

Near Basal Blood Pressure: A Method Applicable To Clinical Practice, John R. Caldwell

Henry Ford Hospital Medical Journal

A method is described for determining near basal blood pressure (NBBP) measurements that is applicable to outpatient clinic or office use in daily practice. In our clinic, patients' mean casual pressure was significantly higher than the NBBP, the difference being 40 mm Hg systolic (p < .001) and 18 mm Hg diastolic (p < .001). In hospitalized patients the casual blood pressure was higher than the fourth to sixth day hospital average, and the hospital average was higher than NBBP. The difference between the last two was 15 mm Hg systolic (p <. 005) and 9 mm Hg diastolic (p < .005). In patients recording blood pressure readings at home the average weekly home-recorded blood pressure was not significantly different from NBBP during the same week, -1 mm Hg systolic (p > .80) and 4 mm Hg diastolic (p > .10). NBBP by this method offers a practical way to estimate the average daily blood pressure.

There is, after all, only one valid use of statistics: to enable oneself to make a personal decision based on the information available.

A Test Of The Simple Recessive Hypothesis For The Inability To Taste Phenyl-Thio-Urea: A Family Study, Susan I. Wolf

Dissertations and Theses

This thesis is a report on the analysis of family data gathered to test the simple recessive hypothesis for the inability to taste phenyl-thio-urea (P.T.C.). The simple recessive hypothesis states that the inability of a minority of persons to taste high concentrations of P.T.C. is due to the action of an autosomal recessive gene in the homozygous condition.

Tool-Making And Tool-Using In The Northern Blue Jay, Thony B. Jones, Alan Kamil

Papers in Behavior in Biological Sciences

Laboratory-raised Northern blue jays (Cyanocitta cristata) have been observed tearing pieces from pages of newspaper and utilizing them as tools to rake in food pellets which were otherwise out of reach. The frequency of this behavior was dependent upon the motivational state of the jay and the presence of food pellets.

Predicting Primary Productivity In Westhampton Lake, Richmond, Virginia., Gary Newton Moore

Master's Theses

Several predictive photosynthetic models were tested using light, temperature, nutrient, chlorophyll, and primary productivity data collected from Westhampton Lake, Richmond, Virginia from February-September, 1972. A simple linear model, the Kendall rank correlation coefficient, was used to relate photosynthesis to individual meteorological, physical, chemical, and biological factors. iii Of the parameters measured, only the daily maximum photosynthetic efficiency ((P/chl) max ) was significantly correlated with photosynthesis. Five multiple factor (non-linear) models were tested. In the best fitting model, primary productivity was a function of the maximum observed ratio of photosynthesis/chlorophyll concentration, light intensity, temperature, nutrient concentrations, and chlorophyll concentration. The Pearson …

Effects Of Temperature And Ph On The Growth And Composition Of The Sporophyte And Gametophyte Generations Of Allomyces Arbusculus Butler (1911), Lawrence Wayne Lenz

Master's Theses

Pure cultures of the sporophyte and gametophyte generations of Allomyces arbusculus Butler (1911) were grown under varied conditions of temperature and pH. On solid media the gametophyte did not grow at 10 and 15 C; the sporophyte began slow growth after a long lag period at 15 C. There were no significant differences in growth between the sporophyte and gametophyte at 20 and 25 C. Increasing colony areas occurred for both generations at temperatures between 30 and 40 C, with the largest amount of growth for either generation at 35 C.

Colonies grown in broth media at various pH levels …

Mechanisms Of Population Regulation In Confined Colonies Of Peromyscus Maniculatus (Wagner) And The Response To Exploitation, Donna Corn Olsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wild-trapped and laboratory-reared Peromyscus maniculatus (Wagner) were raised as confined colonies indoors with various stocking densities ranging from 0.026 to 0.100 mice per sq. ft. in pens of 40, 77, and 154 sq. ft. The animals were individually tagged and all pens were censused at weekly or semi-monthly intervals to record animals present, body weights, food consumption, and overt reproductive condition. At the termination of each experiment, all mice were necropsied and organ weights of gonads and adrenals recorded. Histological sections were made of the testes and ovaries. Half the colonies were subjected to density-independent exploitation by removal of 50% …

Factors Affecting Feeding Habits Of Sheep Grazing Foothill Ranges Of Northern Utah, Farid D. Iskander

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An experiment was designed to study the effects of forage availability, season and intensity of grazing, and distribution and behavior of sheep on their forage preferences. Three grazing periods of 15 days each were used to study the effect of season. Each grazing period included a heavy and a moderate stocking intensity. Pastures were divided by a grid into 30.48 m x 30.48 m compartments. Each compartment was sampled for botanical composition of available herbage prior to and after grazing. Esophageally fistulated sheep were allowed to graze freely and positions of individual sheep with respect t o compartments were recorded …

An Approach To Range Inventory For The Annual Range Type Of The Arid And Semi-Arid Regions Of The Sudan, Farid D. Iskander

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

Range inventory, by definition, is the evaluation of the range resources to determine a proper and safe level of stocking and to provide a record of vegetation and vegetation changes (Stoddart and Smith, 1955). Range survey is defined by the Range Conservation Glossary, Soil Conservation Service (1944) as "a systematic and comprehensive inventory and analysis of the range resources and related management problems of a range area for the purpose of developing plans of management therefrom." Accordingly, range inventory is the quest for basic information about rangelands and the development of guides and procedures for their management, improvement and efficient …
