Effect Of Gibberellic Acid And Chilling On Nucleic Acids During Germination Of Dormant Peach Seed, Yuh-Nan Lin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study of nucleic acid changes influenced by gibberellic acid and chilling treatments in peach seed was performed in an attempt to reach a better understanding of the mechanism involved in breaking seed dormancy.

Gibberellic acid and the chilling treatment increased the RNA content. These two treatments which break dormancy also increased RNA, suggesting a similar mechanism involving RNA. Chilled seeds contained more RNA than did the gibberellic acid treated seeds.

DNA content remained unchanged regardless of treatment.

Dry seed had a greater ribonuclease activity than with soaked seeds. Enzyme changes did not correlate well with the RNA content in …

Teacher's Attitudes And Teacher's And Student's Knowledge Of Alcohol And Alcoholism In Selected Utah High Schools, Ladawn Anderson Gibbons

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A comparison of teacher's attitudes and teacher's and student's knowledge of alcohol and alcoholism were studied in nine selected high schools in Utah.

It was found that some teachers knew important positive facts about alcohol and alcoholism, but when personal obligations were written into "attitude" questions, their responses changed.

Some health and driver education teachers were poorly informed on the subject of alcohol and alcoholism. Some important facts known by teachers were either being deleted from instruction on alcohol or not being communicated very well.

In some schools it appears that students are learning about alcohol and alcoholism from other …

Tests Of Methods That Control Round-Off Error, Dale M. Rasmuson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Methods of controlling round-off error in one-step methods in the numerical solution of ordinary differential equations are compared. A new Algorithm called theoretical cumulative rounding is formulated. Round-off error bounds are obtained for single precision, and theoretical cumulative rounding. Limits of these bounds are obtained as the step length approaches zero. It is shown that the limit of the bound on the round-off error is unbounded for single precision and double precision, is constant for theoretical partial double precision, and is zero for theoretical cumulative rounding.

The limits of round-off bounds are not obtainable in actual practice. The round-off error …

Algebraic Properties Of Endomorphisms Of Abelian Groups And Rings, Johnnie George Slagle

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The main objective of the thesis was to extend the definition of an M-Group to what is called an M-Ring. From this extension a system called an expanded ring follows naturally. To facilitate the development of the expanded ring, chapter I is devoted to developing properties on systems that are not quite rings where many interesting examples are constructed. In chapter II the definition of an M-Ring is given and some of its properties are derived. In chapter III some of the properties of expanded rings are proved, and examples of expanded rings are given to show their existence.

Differential Cross Section For Electron Positron Pair Production From Neutron Proton Scattering, Robert Dalton Wheeler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The differential cross section for a neutron-proton collision forming an electron-positron pair is calculated. The interaction between the neutron and proton is assumed to be pseudo-scalar and that between the proton and the pair electromagnetic. The interaction between the pair and the neutron is assumed negligible.

The methods used to obtain the matrix elements of the process follows that of Möller. The calculation is therefore based on retarded interaction and is relativistic. In obtaining the square of the matrix elements the initial and final polarization states were not considered. The usual projection operator methods were then applied to the intermediate …

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 …

A Planning Analysis Of Utah Lake To Determine Its Recreational Potential, Robert D. Talbert

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Utah Lake, located near Provo, Utah, is a lake of relatively low recreational development. There are certain inherent conditions that contribute to this situation.

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 …
