The Construction Of Two Light Sources With Adequate Intensity For Magneto-Optical Rotatory Dispersion Experiments, Norman D. Love

Masters Theses

Chapter I

Introduction

The phenomenon known as the Faraday Effect was discovered by Michael Faraday in the year 1845.¹ He discovered that when an isotropic substance of high refractive index is placed in a strong magnetic field which is parallel to a beam of plane polarized light, the plane of polarization is rotated. The rotation is proportional to H, the strength of the magnetic field; and to 1, the length of the light path in the sample. If X represents the rotation in minutes then

X = VH1.

The proportionality constant V is known as Verdet's constant. The units …

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 Method Of Evaluating First Line Supervisory Training, Benjamin I. Killian

Masters Theses

Preface

This study is prepared to establish a method of evaluating supervisory training. An attempt to evaluate the following hypotheses will be considered: (1) There is a method of selecting the basic performance areas of a first line supervisor. (2) There are acceptable standards of performance in the basic area. (3) Performance appraisals prior to the introduction of training will determine sub-standard performance in the selected areas. (4) Follow-up performance appraisals will indicate the effectiveness of training in improving performance without undue contamination of the criteria by other influences.

During the study other areas of investigation to be examined are: …

Geology Of The Esterbrook Area, Converse And Albany Counties, Wyoming, Michael Nolan Greeley

Masters Theses

"The Esterbrook area lies within the Laramie Range in Converse and Albany Counties, Wyoming. Exposures include Precambrian metamorphic and igneous rocks, the Tertiary White River formation, and Quaternary alluvium.

Hornblende schist and mica-quartz schist comprise the Precambrian metamorphic rocks. Foliation planes of these rocks trend northeast and dip steeply to the southeast. Metamorphic rocks of younger age probably lie to the southeast.

A distinctive, Precambrian silicic pluton of biotite-leucogranite with marginal zones of muscovite-leucogranite and alaskite passively intrudes the metamorphic rocks, generally parallel to the foliation trends. Numerous granite pegmatites show a zonal distribution around the pluton and appear to …

Variation Of Sensitized Fluorescence With Penetration Depth Of Incident 2537a Radiation, George Grayson Robinson

Masters Theses

"An investigation of the sensitized fluorescence of a thallium and mercury mixture using a variable depth cell and photomultiplier type of detection is discussed. Data are given to indicate the variation of the intensity of the 3519A thallium line as a function of thallium temperature, as a function of mercury temperature, and as a function of cell depth. Explanations of results require the use of generally accepted ideas concerning energy transfer, emission, and absorption."

Predicted Transient Response Of Complex Poles By Means Of A Residue Ratio, Rameshchandra Shankerbhai Patel

Masters Theses

"Transient response plays an important role in servomechanism, electronic and electrical circuits. A time response of a linear system is the intuitive and immediately comprehensible description of the system performance. The utility of the system performance in television and high speed computer circuits can be determined by its transient characteristics. By locating certain points on the transient response curve the designer is enabled to predict the shape of the response with some precision. The choice of the overall transfer function (or location of the system singularities on the s-plane plot) is decided by speed, accuracy and stability of the response …

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 …

The Reaction Of N-Magnesium Halides On Nitriles In The Synthesis Of Amidines, Robert Bauer

Masters Theses

Introduction

Compounds of the amidine class have long been of interest because of their therapeutic and pharmacological properties. Members of this class of compounds have been shown to be effective in combating pathological conditions ranging from virus (11), bacterial (12), and protozoal infections (7) to diseases of the circulatory system (6), neoplasms (5) and hyperglucemia (21), Since many basic nitrogen compounds have been of interest in cancer chemotherapy, such as a variety of amino alcohols shown by the Upjohn Company to have anti-tumoral activity, it was felt that additional investigations into the use of amidines and amino amidines in this …

“The solution of the general polynomial equation f (x) = O, where f(x) = a_nxⁿ + a_n-1x^n-1 + … + a₁x = a_o, has received the attention of many mathematicians for hundreds of years and is at present in a very highly developed state. Even a cursory examination of the literature will reveal many volumes on this subject. However, this study is concerned primarily with the numerical methods for solving polynomial equations, hence the classical methods will be treated here only as they contribute to this field.

Virtually all of …

Seismic Investigation Of Flint Clay Deposits In East Central Missouri, Roland D. Dayley

Masters Theses

"Seismic refraction surveys were conducted in several localities within the east central Missouri clay districts in order to determine the applicability and economy of this method as a clay exploration tool. Results of these surveys revealed that the sink-type clay deposits possess lithologic and structural characteristics that lend themselves favorably to this method of exploration.

Seismic records obtained from profiles shot across known deposits indicate that several factors other than velocity contrast serve to produce apparent seismic anomalies.

Some unforeseen time loss and expense was encountered because of malfunctions of the seismic equipment employed, which necessitated the purchase and installation …

Study Of The Design Of Reinforcement For Prestressed Concrete And Blocks, Charles Robert Hoffman

Masters Theses

"This thesis is an analysis of the transverse tensile stress condition in an end block of a prestressed concrete beam. A stress analysis was made by photoelasticity and compared to the mathematical solutions and experimental solutions performed by others on concrete models. The photoelastic model was made from a piece of Columbia Resin, 39.

Whatever method is chosen to determine the stress condition, there is no exact code that can be established to fit the various type problems which arise"--Abstract, page 1.

Porous Cooling Of A Pile, Tarsem Singh Purewal

Masters Theses

"In this investigation the problem of a limiting case of steady state one dimensional solid-fluid Newtonian heat transfer is examined in which an incompressible non-heat generating coolant fluid is flowing through a heat generating porous plate.

The effect of grain size on the Newtonian heat transfer in the porous plate with various kinds of internal heat generations is determined analytically. The temperature difference between the solid and the coolant fluid through the porous plate is determined. All the previous studies assume that in the porous plate, coolant fluid temperature and solid temperatures are approximately equal. This analysis eliminates this simplifying …

Mechanics Of The Voussoir Arch As Applied To Block Caving, Christopher Haycocks

Masters Theses

"The theories of ground failure in massive rock with special reference to the problem of the mechanics of block caving were studied and evaluated.

The mechanics of arch or dome formation underground were studied quantitatively using the Voussoir arch theory. The effect of shear stress on the arch stability was considered and found to affect the system only when the arch height increased beyond certain limits.

A theory of the mechanism of ground failure in an undercut block using the dome theory was advanced. Photo- elastic model studies were used to support the conclusions reached"--Abstract, page i.

A Model Study Of The Behavior Of Elastic Liners In Shallow Underground Openings, Martin Samuel Oudenhoven

Masters Theses

"Models of epoxy resin were used in a stress freezing technique to determine areas of possible failure in lined circular openings. These models were loaded in a centrifuge for a fixed period of time, after which they were analyzed photoelastically. The material characteristic changes, with time, were recorded on graphs and used in the analysis.

Two types of tests were conducted; one, where the lining thickness was changed and, the other, where materials of the liner and plate material were changed.

The resulting analyses furnished proof that the greater the rigidity of the lining, the higher the stress developed in …

A second order servo is selected to be compensated and five d-c prototype and equivalent a-c phase lead compensating networks are designed. The frequency characteristics of the a-c networks are obtained experimentally and these of the d-c networks are obtained analytically. The characteristics of both networks are compared and their differences are studied. The transient characteristics of the d-c and a-c compensated closed-loop systems to a step input …

A Model Study Of The Induction Log Applied To The Detection Of Asymmetrically Located Orebodies, Robert Walter Piekarz

Masters Theses

"This research project was undertaken to determine the possibility of using an induction log of the type applied in petroleum exploration, for the detection of conductive ore- bodies asymmetrically located with respect to a borehole. Since a mathematical analysis would be extremely complex, a model study was conducted, using graphite bodies of various shapes to simulate different modes of mineral occurence.

The investigation showed that these bodies were readily detectable, and were capable of yielding anomalous curves characteristic of their geometry. The values of apparent conductivity decreased rapidly with lateral displacement, from the logging tool, as expected, due to the …

A Preliminary Study Of The Effect Of Heat Treatment On The Strength And Microstructure Of A Glass-Ceramic Material, P. D. Ownby

Masters Theses

"The strength and microstructure of a glass-ceramic material of the composition 53 percent SiO₂, 19 percent Al₂O₃, 15 percent MgO, and 13 percent Li₂O were studied. Cylindrical specimens of glass were formed and heat-treated to six different temperature levels for various time periods. The method of strength testing used was a diametral compression loading technique. It was found that the strength of this material increased initially with heat-treatment but then decreased. The strength characteristics of the completely crystallized glass ceramic material were found to be dependent on the initial nucleation period. Some factors which influenced anomalous crystal growth are described. …

Studies Involving Modification Of The Megregian Method Of Fluoride Determination And Application To Fluoride Balance Studies In Infants, Gene R. Wright

Masters Theses

Introduction

At the request of Dr. Frederick Margolis, M.D., and in association with The Upjohn Company, this research problem was initiated as a participation in the investigation of whether or not fluoride ingested as a constituent of the Upjohn 47-M liquid vitamin preparation is retained in an infant's body to the same extent as is fluoride ingested as the sodium salt by itself--either in solution or in tablet form. The retention patterns may be studied indirectly by measuring the amounts of fluoride excreted in the urine and in the feces during each of a series of equal time intervals after …

Ground Water Investigation In The Southern Half Of Franklin County, Missouri, Kemal Piskin

Masters Theses

"Increasing population and industrialization in Franklin County, Missouri, has led to increased demand for water. Much of this demand will be satisfied from ground water resources. Although the general geology of Franklin County has been mentioned in several publications, no detailed study of structure and ground water geology had been done. This thesis consists of study of stratigraphy, lithology, and geologic structure, and analysis of well log data to determine occurrence and availability of ground water, in the southern half of Franklin County.

Stratigraphy and lithology is compiled from previous literature, modified to agree with well log data. Structural geology …

Foraminifera Of The Cenozoic And Recent Genus Sphaerogypsina Galloway, Wayne C. Horton

Masters Theses

"The morphology of Sphaerogypsina as seen in thin section affords various characters useful in classification] 1) arrangement and composition of the wall (calcareous-perforate, radially crystalline); 2) layering of wall (like Gypsina, without layering or black line, having only microlamellae); 3) shape of test (always spherical); and 4) specific characters: size of test, order/unorder ratio, size of chambers, wall thickness, pore diameter, and type of embryonic apparatus.

Correlation of the above characters has allowed recognition of two new species. Comparisons with other genera strongly suggest placing the genus in the Family Gypsinidae (nom. correct.) rather than in the …

A Study Of Duffing's Equation, Charles Kirby Murch

Masters Theses

"The unforced cases of Duffing's equation and the equation of the simple pendulum are considered by imposing certain conditions on a linear partial differential equation. Geometrical arguments are presented which lead to solutions of the special cases considered.

Undetermined functions of integration in the solutions limit their use to the approximation of systems with small non-linearity"--Abstract, page ii.

The Effect Of The Rolling Load On The Micro-Structure Of Low Carbon Sheet Steel, Jerry Lee Cadden

Masters Theses

"A Stanat 315, two high-four high, combination rolling mill is used to cold roll annealed, low carbon steel strips. A method of measuring the rolling load was presented. The method consisted of constructing a load cell using SR-4 strain gages attached to a steel column. The load cell was placed under the hold down screw of the rolling mill and a known load was applied. The stresses from this load were transferred to the mill housing where another SR-4 strain gage was located. The strain in the mill housing was recorded at the corresponding applied load. During rolling, the strain …
