Some Effects Of Impact Of Low Magnitude On The Deformation Of Prestressed Gypsum Cylinders., Arthur Joe Bush

Masters Theses

"A review of the literature pertaining to the subject is presented. Many series or impacts were made on specimens of gypsum which were already under a static load. A special. repetitive impact machine was used to allow a variety or weights to fall from predetermined heights. Tests were conducted inside a roan constructed especially for these tests. Heat gained or lost through the ceiling and walls was kept at a minilI1um by a lining or aluminum-covered, fiber glass insulation. Temperature and humidity conditions were kept nearly constant by a combination air-conditioner and dehumidifier.

Repetitive loading of the prestressed specimen was …

A Study Of Chemical Stabilization Of The Swell Properties Of Putman Soil, Dale E. Dobson

A Study Of The Haeffner Effect In Mercury, James Nicholson Baysden

Masters Theses

"In 1953, E, Haeffner reported that when he passed a direct electric current through a capillary tube filled with mercury, he obtained a separation in the isotopes of mercury with the heavier isotopes being enriched at the negative terminal and the lighter isotopes at the positive terminal. This effect has since been referred to as the Haeffner Effect, Since the original experiment with mercury, other investigators have observed this effect in many other liquid metal systems.

This investigation of the Haeffner Effect in mercury involves the use of a radioactive isotope of mercury (Hg 203) as a tracer to follow …

Determining Design Freedom Of Linear Feedback Control Systems, Harley D. Brixey

Masters Theses

“The problem confronted in this thesis is to develop a method or procedure to be used in determining the amount of design freedom that is available in any given linear feedback control system by working with the signal flow-graph representation of the system.

Literature was reviewed that deals with basic signal flow-graph theory and degrees of design freedom. Signal- flow-graph theory that forms a foundation for the development is presented.

The development consists of starting with an essential signal-flow graph of order one. The sensitivity and transmittance functions are written for this essential graph in terms of graph symbols; then …

The Design, Construction, And Calibration Of An Apparatus To Determine The Thermal Conductivity Of Solids, Alan Edward Stephenson

Masters Theses

A Study Of The Angular Velocity In A Liquid Induced By A Vortex In An Emptying Container, James Paul Hartman

Masters Theses

"Previously a limited amount of investigation has been done to describe the rotational motion of fluid in a draining tank. To date tank design has been based on trial and error, since the physical mechanisms of actual draining have not been recognized. This investigation has been made to develop a technique for the measurement of the motion of the fluid during the draining process and to present the results of the observed surface velocity of the liquid as a function of depth of fluid and its distance from the center of the vortex core. Many previous investigators of vortex behavior …

The Measurement Of The Life-Time Of The 62P3/2 State Of Thallium, Danny Hale Sokolowski

Masters Theses

The measurement of the lifetime of the metastable 6²P_3/2 state of thallium is discussed. Time-sampling equipment techniques and instantaneous methods of display on an oscilloscope for measuring the lifetime are explained. The lifetime is measured as a function of mercury vapor pressure. The decay of the 5350 A thallium line is also measured to give an indication of the effect of the imprisonment of the 3776 A resonance line. This decay of the 5350 A line is also in a mercury atmosphere"--Abstract, page ii.

Fossil And Recent Beryciform Otoliths: An Adjunct To Ichthyological Classification., C. Kurt. Lamber

Masters Theses

"Otoliths are calcareous bodies, of consistent form, secreted in the auditory labyrinths of some higher fishes. Of three pairs, only the taxonomically important earstones (sagittae) are considered here. Specifically, this study is restricted to the sagittae of beryciform fishes (Order Beryciformes). Removal of some taxa from the order, and the possible relating of others, is suggested.

The morphology of beryciform sagittae is described, and three basic supra-familial groups are recognized. Diagnostic characters for families are given, with diagnoses of genera added. Sagittae of characteristic species are illustrated.

Otoliths of fossil beryciform fishes, as known from specimens and published illustrations, are …

An Investigation Into The Possible Relationship Between Reading Ability And Functional Articulatory Defective Speech, Joan Elizabeth Weir

Masters Theses

Introduction

The purpose of this study is to investigate the relationship between reading disability and defective articulation. An attempt has been made to determine whether or not children with functionally defective articulation have difficulty in reading.

It is conceivable that a deficiency in one or several areas of language development might impede or retard a child's academic achievement and might interfere with his emotional adjustment. This study was, therefore, undertaken, first to determine whether or not there is a difference in the reading ability of speech defective children as determined by valid and reliable measures, and the reading ability of …

On The Use Of Tris (Hydroxymethyl) Aminomethane As A Diluent In Quantitative Analyses Of Soil Bacteria, Barry L. Keller

Masters Theses

Introduction

Many investigations have been conducted in the field of soil microbiology during the past.six decades. Most notable among the contributors is S. A. Waksman whose voluminous works have established many of the procedures used in microbial analyses of soil. Yet, the one fact that is foremost to any reviewer of the literature covering this field is that no standardization of techniques for soil analyses exists. The following presentation deals with one method used to estimate the number of bacteria and actinomycetes in soil.

The use of Tris(hydroxymethyl)aminomethane (hereafter referred to as "Tris") is not new. Tris currently is used …

Specific Language Disability As Related To Clinical Failure In Public School Speech Therapy, G. Lorraine Hansen

Masters Theses

Chapter I

Background of the Problem

Introduction. The term language as used in this thesis refers to the complex symbolic processes of speaking, reading, and writing. Speech is the primary process of language. Reading and writing are secondary processes formed by written symbols which reflect the primary symbols of speech. Due to the integral relationship of these elements, a facility or disability in one might affect the others. If this is true, then it might also be possible that one currently existing factor could affect the entire area of language including any, or all, of the interrelated processes. It is …

Comparison Of Alcohol Offenses Of College Students With Those Of Persons In A Similar Age Group Who Have Not Had College Experience, Cornelis Laban

Masters Theses

Introduction

The purpose of the study was to·make· a comparison of the drunk driving behavior of college students with that· of those persons in a similar age group who have not had college experience. There is very little published information about the statutes governing "driving under the influence of liquor" (D.U.I.L.). The educable nature of persons involved in such offenses 8 and the probable anti-social and sociopathic behavior in individuals leading up to the offenses, also need thorough investigation. Very pertinent also is the question whether or not there is a biological basis for this particular behavior; an understanding of …

A Pilot Study Of The Upper Pitch Limits Of Young Children As Measured By Psychogalvanic Skin Resistance Audiometry, Lawrence M. Smith

Masters Theses

The purpose of this study was to investigate the upper pitch limits of hearing in young children as a test of a hypothesis proposed by Fatsinger (1959).

According to the place theory of hearing, the low pitch sounds are located at the apex or wide part of basilar membrane, and are mediated by the long fibers, and the high pitch sounds at the basal or narrow part of the basilar membrane, and are mediated by the short fibers. Therefore, a size change which involved the basilar membrane could cause a shit in the pitch sensitivity range by producing longer fibers …

A Model Study Of The Application Of Roof Bolts Under Unsymmetrical Loading Conditions, Friedrich H. K. Esser

Masters Theses

"When coal is extracted by the long wall mining method, two gate-roads on either side of the working face are driven with the advancing operation. In the surroundings of these openings the state of stress which existed prior to mining is not only disturbed by the drifting process of the gate-roads but also by the coal extraction in the long wall, resulting in an "unsymmetrical" stress distribution. Varying incremental pressure components and the high complexity of strata movements make it extremely difficult to control the rock behavior under unsymmetrical conditions by conventional support. Application of roof bolts as an auxiliary …

Gathering Haunch Design Data By Photoelasticity, Richard B. Heagler

Masters Theses

"The haunching of beams and columns and the haunching of rigid frames is performed by design engineers for the purpose of relieving stress concentrations that might occur at discontinuities in structures. The haunch performs this relieving of stress concentration by increasing the rigidity of the structure at regions of high stress. Usually this design step is one of trial and error; that is, the engineer will select a haunch or method of haunching and then check to see if the result is sufficient for his purpose. This can be a time consuming process and can lead to uneconomical design.
