Studies On The Conversion Of Indole Acetic Acid And Oxindole Acetic Acid By Hygrophorous Conicus, Barbara Ruth Patterson

Masters Theses

"The fungus, Hygrophorous conicus, produces the enzyme, indole acetic acid oxidase, when grown in the presence of indole acetic acid (IAA) or tryptamine. The IAA acts both as an inducer and a substrate for this intracellular enzyme. The product of the oxidation catalyzed by the IAA oxidase is oxindole acetic acid (OIAA). Since the IAA and OIAA absorb maximally at two different wavelengths the use of spectrophotometric analysis was possible for assaying for the IAA oxidase activity. Paper chromatography was used for qualitative identification of the IAA and OIAA. The rate of growth and the rate of formation of the …

The Effect Of Cadmium On Anaerobic Digestion, Lyle Lynn Pruitt

Masters Theses

"The main purpose of this study was to determine the effect of cadmium on anaerobic digestion. Metal concentrations in the form of regular and slug doses were considered. The possibility of acclimating anaerobic bacteria to higher cadmium levels was studied, and attempts were made to reestablish digestive action through re-seeding in digesters overcome by high cadmium concentrations"--Abstract, page [ii].

An Evaluation Of The Feasibility Of Neutron Microradiography, Maynard L. Arment

Masters Theses

"The metal working industry has used metallography and microradiography extensively in the past decade. X-ray or gamma microradiography has several advantages as compared to metallography, but a disadvantage concerning alloys of adjacent elements; microradiography cannot distinguish between elements 2 or less atomic numbers apart. Attempts were made using neutron microradiography to distinguish between cadmium and tin rich grains. A maximum resolution of 0.017 inches was found with a calculated possibility of a resolution less than 0.002 inches"--Abstract, page ii.

An Investigation Of The Effect Of Auditory And Combined Auditory-Visual Cues Upon Judged Intelligibility Of Artificial Larynx Speech And Esophageal Speech, Mary Ellen Carder

Masters Theses

Introduction

Surveys have shown that the incidence of total laryngectomy, surgical removal of the larynx, has increased steadily in the United States since 1947 when a total of 846 cases were reported (19, 20), to the present time when cancer registries indicate that about 4,400 new cases of cancer of the larynx are discovered annually (13). While it is estimated that in the United States at the present time there are 15,000 to 20,000 individuals who have undergone surgical removal of the larynx due to a carcinomatous condition of that organ (27), it is probable that the total population of …

A Study Of Certain Effects Of Local And Topical Anesthetics On The Speech Of Stutterers, Charles Michael Gross

Masters Theses

Chapter I

Introduction

Introductory Statement

The ability to monitor one's own vocal output is essential if one is to produce and maintain normal speech. Speech would become progressively defective if one were unable to detect errors in voice, articulation, or rate. The preservation and maintenance of speech require the coordination of several automatic systems in the human body. One of these systems includes the tactual-kinesthetic purpose of defining the tactual-kinesthetic role and its relation to feedback cues in the production of speech.

Since speech is controlled by more than one automatic feedback system, it is essential that an investigation of …

An Evaluation Of Alcohol Education Materials In Elementary, Junior High School, And Senior High School Textbooks As Rei.Ated To Student Needs, Daniel L. Paul

Masters Theses

Every state in the United States has statutory provisions requiring alcohol education in the public schools . The earliest of these laws dates back to 1858.Taking these facts into account one might assume that by this time, alcohol education programs would be well established and clearly defined, but most authorities in the field would say that this assumption is incorrect. The reasons for the failure of alcohol education programs to become well established are many and complicated, and are not the function of this paper to discuss except for one aspect, which is one of the contributing factors to this …

The Reaction To Ketoacylhydrazones With Lead Tetraacetate, Lavern M. Weisenberger

Masters Theses

Introduction

It has been shown that ketohydrazones react with lead tetraacetate to give azoacetates in good yields (11) according to the following equation:

R₂C=N-NH-R + Pb(OAc)₄ → R₂C(OAc)-N=N-R + Pb(OAe)₂ + HOAc

The reaction of the structurally related 4,4- disubstituted ketosemicarbazones with lead tetraacetate quite unexpectedly gave carbamates in good yields (10) presumably according to the following equation:

R₂C=N-NH-Co-NR₂ + Pb(OAc)4 → R₂C-O-CO-NR₂ + N₂ + Pb(OAc)₂ + HOAc

A Study Of The Government Of Parchment, Michigan, Shirley Forbes Swenson

Masters Theses

Introduction

Suburban-living has become a major part of our culture and the term has been widely accepted and interpreted to mean a distinctive way of life highly advantaged over life in strictly urban or rural settings. The first major move to the suburbs was by the wealthier segments of our society, and the gracious, leisurely pattern of living they sought still colors the popular image of the term "suburban."

Ailred Of Riveaulx The Consistency Of His Life And Writings With His Thought And His Profession As Cistercian Monk, Tyrrell Hughes

Masters Theses

First paragraph:

The author confesses to a profound emotional involvement with AiIred of Rievaulx, Saint of the Church and man whose love was charity, the love that is like God's love. But this zealousness on his behalf was born after analysis of and reflection on Ailred's life and writings, comparing these judgments with the treatments he has received at the hands of various scholars, among them the fine names of David Knowles, F.M. Powicke, C. H. Talbot and Aelred Squire. The initial reaction induced by the comparison was indignation at the injustice done AiIred, but much more at the seeming …

Construction And Validation Of Six Mental Health Sub-Scales By Age, Sex, And Educational Status, Thomas James Boynton

Masters Theses

Chapter I

Introduction

Purpose of the Study

The topic considered in this thesis is the construction and validation of six mental health sub-scales which are based upon procedures controlling for age, sex, and educational status. Each item in a 22 item mental health scale is tested for validity by age, sex, and educational status. Six sub-scales, one for each dichotomy of the three social groups, are constructed from this procedure. The validity of these sub-scales is then tested via six different criteria of mental health. Finally, the validity of the six sub-scales, the original 22 item scale, and a related …

Analysis Of The Relationship Of Items On An Employment Application To Length Of Service, Margery Hidenach White

Masters Theses

Certain factors on an application blank may be predictive of length of service and of job success. If personal history items which successfully differentiate between the short-term and long-term employee or the desirable and undesirable employee can be identified, it would assist in the selection process.

A review of recent research concerning factors on an employment application as related to job success reveals that, although considerable research was done in this area during the early 19SO's, there has not been much published in the past two years. Apparently there are three reasons for this: (1) early results indicated high validity …

An Investigation Of Employee Attitudes And Employee Performance, Richard V. Washburn

Masters Theses

Industrial managers are showing an increasing interest in employee attitudes, opinions and morale. This conclusion is reflected in the fact that many companies conduct attitude and opinion surveys, train their supervisors in human relations and provide other functions designed to create favorable attitudes.

Management concern for the promotion of favorable employee attitudes may be attributed to two main factors. Part of the concern may be attributed to a general trend toward greater social responsibilities of industry. The other, and perhaps greater part can be attributed to an assumption that employees with favorable attitudes are more productive than those with generally …

I work very slowly on my lecture. My strength is failing and my eyes are so that I cannot use them by candlelight. I have many pages written with pencil and when I can get them copied in ink, I will send them to you.

My object in trying to have this printed is that it might live after I am dead and finally be adopted as the plan or means to bring about the true development of American Indians.

My days are numbered, as I am entirely unable to do any manual labor, not only from old age …

An Investigation Into The Possible Relationship Between Phonic Ability And Articulatory Defectiveness In University Students, Ralph W. Redel

Masters Theses

Introduction

Background

In 1938, Travis and Rasmus commented on a particular problem in pathology. They said, "From every angle, an adult with a disorder of articulation presents a much more serious problem than a child with such a defect" (40. p. 218). Their statement is an appropriate current evaluation of the same problem. The American Speech and Hearing Association's Committee on the Midcentury White House Conference reported that the incidence of articulatory disorders was equal, 3.3% for both children and adults in the United States (1). In 1962, Dopheide found that 36 out of 2,087 of the freshman entering Western …

An Investigation Of The Influence Of Certain Phonetic Contexts Upon Articulation Of The /S/ Sound, Theodore J. Peters

Masters Theses

Chapter I

The Background and Purpose of the Study

Introduction

Clinical experience as well as considerable research, which will be discussed later in this chapter, has shown that children are inconsistent in their misarticulation of speech sounds. Children who typically misarticulate a sound may, nevertheless, articulate the sound correctly in certain words. Several authors have suggested that these occasional correct productions of the usually misarticulated sound can be useful in therapy. For example, in a discussion of therapy techniques Van Riper (32, p. 273) has recommended the use of "key words" in helping a child correct his articulation errors:

And Yet I Have Loved Him: The Judgement Of William Of Saint Thierry On Peter Abelard, Rozanne Elder

Masters Theses

First paragraph:

On the second of June in the year 1140, a Council of the Church in Sens formally condemned as heretical nineteen propositions from the works of Peter Abelard, philosopher, theologian, and teacher of unparalleled popularity. Denying emphatically that his teaching varied in any way from that of the Church, Abelard appealed to Rome, only to have Innocent II uphold the decision of the Council. He upheld the condemnation of Abelard’s works, ordered his writings to be burned, forbade him ever again to teach, and, finally, ordered him to perpetual penance. The condemnation of Abelard can be laid to …

The Reaction Of Ketosemicarbazones With Lead Tetraacetate, Thomas M. Davies

Masters Theses

Introduction

It has been demonstrated that lead tetraacetate will oxidize ketohydrazones to azoacetates in good yields (11).

R₂C=N-NH-R + Pb(OAc)₄ ------> R₂C(OAc)-N=N-R + Pb(OAc)₂ + HOAc

Since ketosemicarbazones are structurally equivalent to ketohydrazones, it was thought that the reaction of ketosemicarbazones with lead tetraacetate would proceed in a similar manner. Originally the object of this research was to prepare a series of new azo compounds related to semicarbazones by lead tetraacetate oxidation.

The Indole Acetic Acid Oxidase Of Hygrophorus Conicus., Dilip N. Patel

Masters Theses

"The purpose of this investigation was to determine an assay method for measuring the activity of the indole acetic acid oxidase present in Hygrophorus conicus. This enzyme converts tryptamine or indole acetic acid (IAA) into oxindole acetic acid (OIAA).

An assay method for measuring the activity of the enzyme was developed based on the spectrophotometric measurement of tryptamine, IAA, and OIAA. Several other assay methods were tried. The colorimetric method of Gordon and Weber ^(l4) was found to be useful for a quantitative determination of IAA and was insensitive to OIAA. Paper chromatography proved to be useful as a qualitative …

Artifact Filter., Kent William Swearingen

Masters Theses

"Peripheral blood pulse monitors are highly susceptible to noise-artifact-- in their present stage of development. The purpose of this thesis is to demonstrate a feasible means for filtering the artifact, using existing monitors. Since no peripheral pulse monitor (transducer) was available for experimentation, a simulated test input was devised with frequency variations from JO cycles/minute to 1.50 cycles/minute.

The filtering circuit predicts the time location of each input pulse. The location of the prediction is governed by the accuracy of the preceding prediction. This is controlled by an R-C timing circuit with a Schmitt Trigger and relay.

From the data …

The Removal Of Residual Organic Materials From Sewage Plant Effluents Using Continuous Foam Flotation., Ajab S. Malik

Masters Theses

"This investigation was conducted to determine the feasibility of using a continuous foam flotation process for the removal of soluble organic materials from sewage treatment plant effluents. All effluents contained alkyl benzene sulfonates (ABS), derived from synthetic detergents. The studies were conducted on a laboratory scale. The reduction in the chemical oxygen demand was used as a measure of the effectiveness of the removal of the organic materials.

A flotation cell, equipped with the means of controlling the air and liquid flow rates, was used. Air flow …

The Toxic Effects And Fate Of Selected Pesticides In Natural Water., Donald Lee Evans

Masters Theses

"The extensive application of synthetic organic pesticides in the United States has created many problems, particularly with respect to fish life. While a number of investigations have been undertaken to determine the toxicity of several pesticides to various species of fish, a great deal of research work is needed before the problem is completely understood.

The individual toxicities of DDT, BHC, 2.,4-D, and Sevin to western golden shiners were determined by means of the bioassay procedure at a t empera t ure Of 16oc. The four chemicals studied were found to be toxic to the test fish with Median Tolerance …
