Taxonomic Study Of Fossil And Recent Otoliths Of Certain Cuskeels, Gary Neal Pointer

Masters Theses

"Otoliths are calcareous structures occurring in the auditory labyrinths of teleost (bony) fishes. Three pairs of these earstones normally are found: the sagitta, in the sacculus; the asteriscus, in the lagena; and the lapillus in the utriculus. In fishes other than the Order cypriniformes (carp, catfishes, and related forms), the sagitta is the largest otolith, and it may be used in taxonomic and other studies. Fossil earstones of cuskeels (Family Ophidiiae-Brotulidae), constituting the Preophidion complex, occur in relative abundance at various levels in the Claiborne, Jackson, and Vicksburg groups of the Lower Tertiary on the Gulf Coast. The present study …

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 …

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

Some Effects Of Photoperiodicity On The Temperatures And Weights Of Bobwhites, Bernard J. Cripps

Masters Theses

Introduction

In recent years there have been a number of studies that have dealt with body temperature and body weight variations in gallinaceous birds under various field or controlled conditions. Wilson (1948) studied the reactions of pullets to different environmental temperatures. In a laboratory experiment Bajpai (1962) observed that a change in the cloacal temperature of adult Rhode Island Red males was effected by manipulating the photo-period. In a report on the sexual maturation of Coturnix quail Wilson et al. (1962) discussed several aspects of variation in body weight, which resulted from changes in photo-period. Hamilton (1957) studied the weights …

An Investigation Of The Influence Of The Suprapharyngeal Ganglia Upon Water Balance And On Osmoregulation In Lumbricus Terrestris, Richard M. Dennany

Masters Theses

Chapter I

Introduction

In the central nervous system of most animals which have been examined some neurons show cytological characteristics of gland cells. These cells are now recognized as a specialized cell type and designated neurosecretory cells.

These neurosecretory cells are capable of elaborating secretory material which is accumulated as granules in the body of the nerve cell and in the axon-endings. They release complex organic substances, neurohormones, which act as hormones and are often liberated into the blood stream (Welsh, 1958). These specialized neurons are capable of receiving impulses from other neurons although their axons do not end in …

The objective of this study was to prepare a detailed description of the muscles of the pectoral girdle of M. pennsylvanicus and to compare them to P. ochrogaster. It was hoped that the study might indicate similarities and dissimilarities in the ways in which the two species have adapted to their mode of life and show whether or not they share common adaptations of the pectoral …

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 …

Relation Between Use Of Lincomycin And Outgrowth Of Yeast, Howard W. Clapp

Masters Theses

Introduction

The use of antibiotics has increased the average life expectancy of mankind. They have prevented and cured infectious diseases that previously terminated in death. Consequently, recovery is often prompt and complete.

Though a benefit to mankind, the use of antibiotics in the treatment of infectious disease has also been accompanied by new problems. For example, treatment of a primary infection such as a bacterial pneumonitis with a broad spectrum antibiotic, may result in the death of some of the bacteria. More than one species of bacteria, however, are often found in the infected area. If such be the situation, …

Investigation Of Possible Autotoxicity In Daucus Carota L., Carole Greer Smith

Masters Theses

Section I

Introduction

Results of recent research indicate the probable existence of plant-produced chemical substances which affect the behavior of other plants. Germination-inhibiting, and growth-inhibiting substances have been found to be widely distributed throughout the Plant Kingdom (Garb, 1960). Although the presence of inhibitors has been demonstrated in laboratory experiments, their ecological significance has not been clearly defined.

A preliminary study by the writer indicated the probability of autotoxicity in Daucus carota L., a biennial common to fields and roadsides in the northeastern United States. This study suggested the following investigation which was undertaken to determine more specifically the effects …

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 …

Christianity Encounters Totalitarianism In Germany, Viola M. Gross

Masters Theses

First paragraph:

The German Church of the twentieth century offers a unique opportunity for study. It has twice faced a totalitarian government and has needed to learn to exist and carry on its witness to the Word of God in the face of almost insurmountable obstacles. The purpose of this paper is to contrast and compare the answer of the Church and the Christian to the National Socialists and to the Communists in East Germany, and to determine if possible if Christianity has learned the way through its desperate struggle in this century to continue its task under a hostile …

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 …
