New Genera And Species Of Myripristid Fishe~ In The Gulf Coast Cenozoic, Known From Otoliths (Pisces, Beryciformes), Donna L. Frizzell, C. Kurt Lamber

Missouri School of Mines and Metallurgy Bulletins

Studies of fossil and Recent otoliths (sagittae) supply an important line of evidence, bearing on classification of teleost fishes, supplementary to that of anatomy, osteology, and "phylogenetic" paleo ichthyology.

Squirrelfishes (" Holocentridae" of authors) are generalized forms in which evolutionary divergence of some magnitude is reflected in unpreservable details of anatomy, inconspicuous skeletal structures, and striking differentiation of the sagittae. Otoliths show the holocentroid complex to consist of one homogeneous unit (l\fyripristidae, elevated) and another more heterogeneous group (Holocentridae, restricted). These lineages have been separated at least since the middle Eocene.

A revised classification, based on available lines of evidence …

A Theoretical Investigation Of Periodic Precipitation, Jack M. Scrivner

Masters Theses

"The problem of periodic precipitation in solution or gel is considered from the standpoint of supplementing the simple diffusion equation with chemical reaction rate terms. This addition has the effect of making the differential equations of the process non-linear.

The system of equations admits of a periodic, steady-state solution under certain conditions, but lack of experimental values for the parameters prohibits a definite statement as to whether or not the model is valid"--Abstract, page ii.

Impact Energy Coupling And Impact Seismic Refraction Using Electronic Timing, Roderick D. Carroll

Masters Theses

"The use of impact energy sources in lieu of explosives for shallow seismic investigations is limited chiefly by the low energy available. Means of increasing the energy transmission of an impact source are investigated, using a weight drop arrangement and an oscilloscope. The energy of refracted arrivals is investigated by direct overburden impacts, compaction of the overburden at the point of impact and the use of steel and aluminum plates as coupling devices. Energy transmission is shown to be greatly increased, using a suitable coupling device and the conditions for optimum coupling are discussed. The elastic constants of the ground …

An Analog Method For The Determination Of The Deflection Of Beams Resting On End Supports And Design Of An Automatic Programming Device, Paul C. Jackson Jr.

Masters Theses

"This investigation shows that beam problems can be solved easily and accurately with an analog computer. Two problems were solved as to their shear, moment, slope and deflection along the length of the beam and the graphs drawn by the analog computer were compared with calculated values. Very little difference was found between them.

An electronic programmer was built to aid in handling beam problems as they were being run on the computer. This was capable of putting into the computer bits of data at specified intervals of time. The programmer proved reliable and repeatable once it was adjusted to …

Electron Microscope Study Of The Systems Cadmium-Cadmium Chloride And Lead-Lead Chloride, Dennis O'Neill

Masters Theses

"The nature of the dispersed phase in the cadmium-cadmium chloride and lead-lead, chloride systems were investigated with the electron microscope.

Preliminary experiments on preparing and examining the dispersed phase showed that it was most feasible to study the material by electron-microscopic examination of replicas made from the surfaces of the fractured materials. Melting apparatus and methods were chosen so that samples of the melts could be easily quenched to different temperatures and so that the samples could be easily fractured with a minimum of surface contamination. Of the conventional replicating techniques tried, that of carbon replicas pre-shadowed with chromium was …

Effect Of Deflections For A Flat Plate By Slope-Deflection-Gyration Method, William Hsin-Loo Ying

Masters Theses

"Since the procedure for the theoretical solution of a rectangular flat plate or slab is complex, many approximate methods for determining the moments and deflections of such plate have recently been developed. One of these methods is the so called Slope-Deflection-Gyration Method which is performed by means of basically well-known structural theories - slope-deflection and torsion.

For a given plate, it is assumed that the plate is to be divided up into a grid of strips or equivalent beams at right angles to each other. The joints of this grid are assumed to be rigidly intersected and be permitted to …

Apparatus For Inductive-Electromagnetic Model Studies, Won Ho Kim

Masters Theses

"The object of this research is to design, construct and calibrate an apparatus suitable for electromagnetic model studies. A portion of the thesis is devoted to general review and theoretical consideration of electromagnetic prospecting.

Theoretical analysis of electromagnetic survey data by mathematical methods can only be carried out for simple idealized subsurface conditions. Because of the difficulties of theoretical solutions, in contrast to the simplicity of the conditions of similitude in electromagnetic exploration, a model experiment offers a very useful means of studying and comparing the response of naturally occuring conducting mineral bodies.

An apparatus suitable for inductive-electromagnetic model studies …

Evaluation Of The Force Constants Of Non-Polar Gases From Viscosity Data, Kei-Sin Wei

Masters Theses

"The analytical expressions for the transport coefficients (i.e. viscosity, thermal conductivity, and diffusivity) of an ideal gas can be derived from the kinetic theory of gases. It is also possible to make these analytical expressions adequate for real gases if the intermolecular forces of attraction and repulsion for these gases have been taken into consideration.

The intermolecular forces have been studied by many investigators. The Lennard-Jones potential is one of the most realistic semi-empirical statements which represents particularly the intermolecular forces of attraction and repulsion for non-polar gases.

The values of the Lennard-Jones potential parameters or the force constants of …

Transpiration Cooling, Herbert S. Brahinsky

Masters Theses

"In the investigation of the problem, it is shown that the process of transpiration cooling is an effective method of cooling. This process may be applied to heat screens or heat shields, as was done in the sample problems worked out here. A porous plate with coolant flowing counter to the flow of heat was used.

The plate temperature is determined by the amount of heat flux, coolant flow, thermal conductivity of the material used as a plate, the specific heat of the fluid, the specific heat of the plate material, the density of the plate material and its porosity. …

Some Aspects Of Miscible Phase Displacement As Applied To The Recovery Of Oil Reservoir Crude, David D. Friend

Masters Theses

"Recent application of the miscible sing displacement process as a method to increase recovery from petroleum reservoirs has resulted in a great deal of laboratory investigation, none of which provided conclusive evidence as to the amount of mixing taking place between the displacing and displaced fluids. This investigation attempts to provide a possible insight into the rate and degree of mixing of two fluids with respect to flow path transversed and the rate of advance of the fluids. The laboratory investigation consisted of displacing a fluid from a packed core with another fluid under completely miscible conditions.

Experimental evidence indicates …

Deformations And Bending Moments For A Building Slab With A Central Opening, Wu Ping-Yung

Masters Theses

"The adaptability of the classical slope-deflection method analysis to the analysis of uniformly loaded building slab is the subject of this study. The paper demonstrates the use of slope-deflection in computing deflections and bending moments in uniformly loaded square building slabs both with and without central square openings. The results obtained are compared with results of other methods found by other investigators.

Numerous methods have been proposed for use in solving plate or slab problems. The exact solution in the form of a fourth order partial differential equation has proved to be of value in relatively few cases where boundary …

The Magnetic Monopole, Thomas E. Kemple

Masters Theses

"Since Dirac has shown that the concept of a magnetic monopole follows from the fundamental laws of quantum mechanics and that it imposes quantization of electric charge, one has reason for taking the magnetic monopole seriously. Such particles, if they exist, would also give symmetry to Maxwell's equations.

A comprehensive review of the literature is presented and all known properties of magnetic poles are discussed. Scattering of mono- poles by heavy nuclei is analyzed in detail and definite mathematical relations are established. All previous experimental work known is outlined and discussed. Definite criteria for identification of monopole tracks in a …

Effect Of Lime & Cement Additives On The Dynamic Modulus Of Elasticity Of A Clay Soil, Ismail Yolar

Masters Theses

"This thesis is a study to determine the values and characteristics of modulus of elasticity and the modulus of rupture of a clay soil stabilized with lime and cement in an effort to pave the way for including these values in design criteria.

The modulus of elasticity and the Poisson's ratio were obtained by sonic method. Specimens were broken in flexure for modulus of rupture. Experiments were performed with; (1) untreated soil, (2) soil with 4, 6, and 12 percent cement additive, (3) soil with a 3 percent lime additive and 0, 4, 6, and 12 percent cement additive, (4) …

A Vacuum Induction Furnace For Pyrometric Cone Equivalent Determinations, Robert E. Farris

Masters Theses

"Various furnaces which are commonly used for P.C.E. determinations were compared from a literature review. The inadequacies of these furnaces were noted and a furnace was designed, constructed, and evaluated in an effort to minimize or eliminate some of the indicated problems. For this furnace heat is developed in opposed cones (susceptors), which are fabricated from 0.005” molybdenum sheet, by induced (induction) currents from a 10 KW vacuum tube generator. The furnace components are enveloped by a pyrex cylinder in which a vacuum (approximately 1 to 5 micron pressure absolute) is maintained during operation"--Abstract, page ii.

A Study Of The Energy Dissipation And The Related Pressures And Velocities Of Cylindrical Tank Type Stilling Basin, Graham Wayne Wood

Masters Theses

"In all hydraulic structures that hold back water, whether for the purpose of power, irrigation or flood control, all must have some means of dissipating the energy that is produced by the movement of the water from the pond or reservoir to the tailrace. The method of dissipation depends largely on downstream conditions, terrain and economics. The dissipator is to prevent scour and the undermining of the dam itself. The construction of any type dissipator should be the best one available for the least cost of construction. However, space limitations may dictate another type of dissipator. It has been recommended …

Certain Features Of Alteration In The Michigan Lavas And Their Genetic Interpretation, Peethambaram Doraibabu

Masters Theses

"The origin of the alteration and copper mineralization in the Keweenawan lavas of the Upper Peninsula of Michigan is one of the well known controversial topics in Economic Geology. The literature on this problem is most extensive and an attempt was made in this thesis to first review as many aspects of the discussion as appeared to be necessary. This portion is necessarily extensive, and it is hoped that some new light has been thrown here on some patterns of approach or thought which, today, can hardly be called scientific.

Next, the observations made in the field, on hand specimens …

A Study Of The Difference Effects On Alpha Solid Solutions Of Oxygen In Titanium Dissolving In Hydrofluoric Acid, Kuo-Chin Chuang

Masters Theses

"Alpha solid solutions of oxygen in titanium dissolving in hydrofluoric acid exhibited a positive difference effect with k values of 5.7, being independent of the concentration of HF, within the compositional range studied 0 to 5 w/o oxygen. This indicates that various TiO_x alloys are polarizable to the same extent by the same strength of anodic current in hydrofluoric acid.

The difference effect observed on TiO_x alloys dissolving in HF-HCl revealed that the effect is dependent on the oxygen content of the solid solution as well as on the concentration of HCl. The presence of HCl results in …

Tank Studies Of The Resistivity Horizontal Profiling Method Of Electrical Prospecting, Edward Hornsey

Masters Theses

"This research project was undertaken to perfect a technique whereby theoretical horizontal resistivity profiles could be reproduced in laboratory tank studies.

Several specimen materials were tried and finally an acceptable specimen material was found. It was found that carbon specimens suspended in salt water would give horizontal resistivity profiles that agree to a remarkable degree with the theoretically predicted curves.

The investigations showed that the depth of burial of the specimen has a marked influence on the position of the characteristic edge effects and on the magnitude of the apparent resistivity.

The studies also indicated that successful tank studies could …

An Evaluation Of The Addition Of Magnesium Carbonate To Promote Collapsibility In Sodium Silicate Bonded Cores, Wilfred Durairajan Paul

Masters Theses

"Cores are separate sand masses included in the mold to accomplish shapes that would be impossible or difficult to obtain with a normal simple mold cavity.

For example a core made for a pipe casting is expected, first, to support itself when placed in the mold and also withstand handling at room temperature. Second, it should withstand, for a short time, the high temperature of molten metal. Last, it should possess the ability, to completely lose its strength just after the metal around it has completely solidified.

Until recently cores for castings were made using oil bonded sands, with an …

The Effects Of Sulphur And Copper On Hot-Workability Of Pure Iron, Hung-Chi Chao

Masters Theses

"The independent effects of sulphur, copper and their combinations on the hot-workability of pure iron free from other elements was studied, with special emphasis on the red-short phenomenon. Electrolytic pure iron with the addition of 0.023 cent sulphur, 0.33 per cent copper and 0.024 per cent sulphur plus 0.032 per cent copper along with a heat of only electrolytic pure iron was melted under vacuum, and cast under helium pressure. The specimens machined from the forged bars were tested at various temperatures by the hot twist-test and by the constant energy single blow drop forging test to evaluate the hot-workability …

A Study Of Invert Emulsion Drilling Fluids, Edward R. Tegland

Masters Theses

"Since invert emulsions are being applied as drilling fluids to cope with special drilling and completion problems, evaluations of existing and new types of emulsions are needed. Three types of emulsions are evaluated in this study: (1) type A emulsions prepared with a commercial emulsifier, (2) type B emulsions prepared by adding clay to the external phase, and (3) type C emulsions containing no externally added emulsifier.

Standard testing procedures were used to measure the viscosity and filtration properties of the emulsions studied. Interfacial tension measurements were made using a technique described in the literature. The degree of stability for …

Use Of Light-Weight Steel Strapping As External Reinforcing To Concrete Beams, John O. Buchanan

Masters Theses

"As a result of some recent failures in reinforced concrete construction throughout the United States, a study was made by several national authorities to find some remedial measures of strengthening existing structures without rebuilding. A system was developed, using high strength steel bands applied externally to beams, to act as stirrups, which has been highly successful. It not only greatly increased the strength of beams already in place but was used to repair members which had already failed.

The application of these bands was made under very exact specifications, using closely controlled procedures, with many physical refinements, in order to …

A Systematic Study Of Experimental Parameters In A Cloud Chamber Search For Subionizers, Zin Aung

Masters Theses

"Since there is no theoretical basis for the quantization of electric charge, it is reasonable to consider the possible existence of particles with charges much less than the electronic charge ‘e’. Such particles, if they exist, are expected to ionize more lightly than the electron. Similar remarks hold true for particles with electric dipole moments, and relativistic monopoles with strengths much less than ’e’ electrostatic units. These particles have been termed subionizers.

The selection of apparatus for a subionizer search has been discussed. The desired conditions for such a search using a low background, long sensitive time Wilson cloud chamber …

Temperature Distribution In An Infinite Plate As A Function Of The Input Heat Flux, George Franklin Wright

Masters Theses

"It is the purpose of this thesis to investigate the effects of a variable input heat flux impinging equally on both sides, on the temperature distribution within an infinite plate. An infinite plate may be defined as one in which the dimensions are infinite in two directions and finite in thickness. For practical purposes such a plate could be thought of as one in which the thickness was small enough, compared to the other two dimensions, so that a temperature gradient exists only normal to the surfaces of the plate. This assumption will be made to establish one-dimensional heat flow …

A Heterocyclic Alkyd Resin, Bhailalbhai M. Patel

Masters Theses

" 'Alkyd’ is a word coined by Kienle in 1927 to designate a class of synthetic resins which include the complexes resulting from the reaction of polyhydric alcohols and resinifying carboxylic organic aromatic acids or their anhydrides. The word in a broad sense is generally considered to apply to many modifications of these resins - drying, semi-drying and non-drying oil-modified alkyds. It was derived from the words alcohol and acid by combining “al” and “cid” and for euphony changing the ”cid” to “kyd” – al(cid)kyd.

Compounds having rings composed solely of carbon atoms are called homocyclic compounds or carbocyclic compounds. …
