A Theorem On Homeomorphic Convergence And Some Applications, Frank J.S. Wang May 1968

A Theorem On Homeomorphic Convergence And Some Applications, Frank J.S. Wang

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

Borsuk [ 3 ] has given interesting conditions under which a certain function space is separable (see Theorem 3. 1 ). We give a proof for Borsuk's Theorem here and we show how it can be used to establish a useful theorem on homeomorphic convergence. We illustrate the utility of the theorem on homeomorphic convergence by stating and proving several of its consequences.

For example we show that the plane (E2) does not contain uncount­ably many pairwise disjoint contina each of which contains a simple triod (Corollary 4. 1 ). We prove that in an uncountable collection G …


Multiplicative Number - Theoretic Functions, Barney Lee Erickson May 1968

Multiplicative Number - Theoretic Functions, Barney Lee Erickson

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

Quite frequently in the study of number theory we become acquainted with special functions which are defined on the set of positive integers. These functions are known as Number-theoretic functions or Arithmetical functions. This report will give some of the general ideas of the multipli­cative number-theoretic functions.

The first part of this report will be devoted to the general develop­ment of such functions by means of definitions and theorems. The second part will consist of generalizations of a particular function, the -r-function.

Throughout this paper, lower case Greek letters will represent real numbers and lower case English letters will represent …


Computer Analysis Of Consumer Attitude And Consumption Data For Fluid Milk Products, James Reed Fisher May 1968

Computer Analysis Of Consumer Attitude And Consumption Data For Fluid Milk Products, James Reed Fisher

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

The American public, with a per capita disposable income currently at an all time high, has become a source of vital concern to dairy market researchers. The unique socio-economic structure of the present generation causes the dairy industry to be concerned with how the consumer view its products. Effective education and advertising programs must be developed to attract the taste and meet the demands of the consumer.

Two factors which greatly influence market research and advertising programs are the attitude of the consumer toward a given product and the relationship of attitude to the degree of actual milk consumption. To …

The data for Snohomish County, Washington were taken from a report on the central places in that county prepared by Brian J. L. Berry and William Garrison of the University of Washington Geography Department.

Evidence is presented to support the conclusion that these two …


Morphological Development In Relation To Cold Hardiness Of Dormant Peach Fruit Buds, Schuyler Dranna Seeley May 1968

Morphological Development In Relation To Cold Hardiness Of Dormant Peach Fruit Buds, Schuyler Dranna Seeley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The morphological development of Elberta peach fruit buds was studied in relation to their cold hardiness.

Morphological development of peach fruit buds was observed beginning with bud differentiation in mid-summer. Flower initiation was essentially complete by September. Growth was slow in the winter months but increased rapidly as anthesis approached. Photomicrographs were taken to substantiate the discussion .

Cold hardiness determinations were made from December until anthesis in April. The hardiness level was greatest during December and remained at a relatively high level until rest ended. Hardiness decreased thereafter. Major losses of hardiness occurred just prior to anthesis.


The Corporate Image Of Utah State University, Jon I. Anderson May 1968

The Corporate Image Of Utah State University, Jon I. Anderson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During the past four years it has been easy to see that there has been no art direction in the visual communications of Utah State University. Recently the university has become aware of the importance of a good public relations program and has taken steps in that direction. Very little thought has been given to the visual design of these public relations though. Advertising gives information, plants ideas, and provokes interest in a service and company, but it must be designed well to be noticed. Corporate image includes many things, but I shall only deal with the visual or graphic …

Temperature And Inoculum Density As Factors Affecting The Pathogenicity Of Rhizoctonia Solani Kühn On Radish, Paul E. Moser

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effect of temperature and inoculum density on the incidence of disease on radish caused by Rhizoctonia solani Kühn was studied. The fungus attacks radish at one or more stages during host development and causes pre- and pose-emergence damping-off, root rot, and storage-organ decay. The isolate of the fungus used in the study was obtained from infected radishes grown in Salt Lake County, Utah.

To determine the effect of temperature on the pathogenicity of R. solani on radish, soil temperatures of 15, 20, 25, and 30 C were used. Varying inoculum densities of 1360, 816, 408, 136, and 0 grams …


The Water Permeability Of Potato Tuber Tissue, Ward Bryce Roberson May 1968

The Water Permeability Of Potato Tuber Tissue, Ward Bryce Roberson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Experiments involving pressure, temperature, salt solutions, decenylsuccinic acid, a surfactant, and respiration inhibitors including azide, dinitrophenol, malonate, and iodoacetic acid were conducted to determine the extent to which the cytoplasm of the parenchymatous cells of the potato tuber influenced the tissue's water filterability.

The amount of water or solution moved through the potato tissue was measured by applying a pressure differential to the solution, forcing it across a 1.0 mm thick disc of tissue which was supported in a pressure filtration apparatus. The solution moved was collected and measured directly. In certain experiments the conductivity of dialysis membrane material was …


Factors Associated With The Penetration And Colonization Of Tomatoes By Verticillium Dahliae, Terry Dee Miller May 1968

Factors Associated With The Penetration And Colonization Of Tomatoes By Verticillium Dahliae, Terry Dee Miller

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Experiments have demonstrated that Verticillium dahliae is capable of direct cortical penetration of roots and of subsequent distribution throughout plants of both resistant (Loran Blood) and susceptible (Meteor) varieties of tomato. Plants were inoculated by the root dip method and planted in sterile soil. After one week the fungus was isolated from the upper portions of both the susceptible and resistant varieties as indicated by growth petiole sections plated on PDA. The distribution of the fungus in the resistant plants was irregular, but in susceptible plants the fungus was isolated regularly from all petiole sections. In experiments using disposable growth …

The Father Role As Seen By A Group Of College Student Fathers, Devona Alice Dean Luke May 1968

The Father Role As Seen By A Group Of College Student Fathers, Devona Alice Dean Luke

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Some literature implies the modern father has abdicated his place as head of the family, but little research has been done to examine the role of the father in the modern American family.

Intensive interviews of 18 college student men who each had at least two children showed that these men are very much concerned with fatherhood and participate actively in the rearing of their children. They feel the father has at least as much responsibility for the rearing of their children as the mother, possibly more. They are involved more in some dimensions of parenthood than others. Those fathers …

Transfer Of Farm Real Estate In Utah, 1961-1964, Howard Rasmus Thomas

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Recorded "arms length" transfers of farm real estate were analyzed to determine factors affecting market value and assessment per acre, and assessment to market value ratios.

The data were aggregated by county and geographical groups. The geographical groups were made up of counties with similar population densities and similar climatic conditions.

Using multiple regression analysis and tabular analysis, size of parcel, quality of land, and distance to Salt Lake City were found to affect market value per acre; size of parcel and quality of land were found to affect assessment and assessment to market value ratios.


The Open-Closed Cognitive Dimension And Divergent-Convergent Abilities, Michael J. Uhes May 1968

The Open-Closed Cognitive Dimension And Divergent-Convergent Abilities, Michael J. Uhes

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The relationship between level of dogmatism and divergent-convergent abilities was investigated in a sample of high school subjects.

Rokeach's Dogmatism Scale, Form E, and tests of divergent and convergent ability were administered to all subjects. On the basis of their performance on the Dogmatism Scale, three experimental groups were formed: high, medium, and low dogmatics.

An analysis of the data showed dogmatism to be negatively correlated with originality, flexibility, composite divergent and composite convergent scores. Fluency was the only ability not negatively correlated with dogmatism. High dogmatic subjects performed convergent operations better than they performed divergent operations, while low dogmatic …
