The Reaction Of N, N-Disubstituted Ketohydrazones With Lead Tetraacetate, Elisabeth Cerda

Masters Theses

Introduction

The reaction of lead tetraacetate with compounds of the following general structure (not able to enter here) was first reported by Iffland and Criner (12). In the case of ketoximes (A = oxygern), a nitrosoacetate was produced which was oxidized to the more stable acetoxy-nitrocompound as follows: (not able to enter here)

The generality of the reaction was established by preparation of a series of acetoxy-nitrocompounds from alicyclic and aliphatic ketoximes. The apparently similar reaction of cyclohexanonephenylhydrazone (A = N-¢) with lead tetraacetate was reported, but the reaction product was not identified.

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 …

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 …

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 …

Geology Of The East-Central Portion Of The Nelson Quadrangle, Clark County, Nevada, Tedral Kantor

Masters Theses

An Investigation Of The Factors Influencing The Design Of A Dense Prilled Ammonium Nitrate-Fuel Oil Mixture, Robert Bartley Hopler Jr.

Masters Theses

"The physical characteristics of dense ammonium nitrate prills were examined. The density was found to be 1.52 grams per cubic centimeter, and from this the specific surface was calculated for the size fractions of interest in the investigation. Theoretical loading densities were calculated for between 26.0 and 47.6 percent voids.

The explosive properties of discrete particle size fractions were investigated. The equation by Clark was found to predict the detonation velocity of the sizes smaller than 8/20 mesh. The equation by Cook could not be applied to dense prilled ammonium nitrate. The possibility of a very oxygen negative condition existing …

Analyses Of Two New Electrode Configurations For Earth Resistivity Surveying, Chi-Chao Chang

Masters Theses

"Two new electrode configurations for the electrical resistivity- surveying are introduced: the A-configuration, consisting of a closely spaced pair of current electrodes separated at larger distance from the closely spaced pair of potential electrodes, and the B-configuration, in which each closely spaced pair consists both current and potential electrode. Because electrode pairs can be carried as units, the new configurations can be applied to continuous resistivity surveying more easily than the Wenner configuration....

Theoretical apparent resistivity values are derived, by Maxwell's theory of images, for the A- and B-configuration over a two layered earth using the depth probe method, and …

A Study Of Viscous Frictional Effects And Relay Characteristics On The Operation Of A Positional Relay Servomechanism, Earl F. Richards

Masters Theses

"The thesis describes some experimentally observed data and analytical approaches to the study of a relay servomechanism. The experimental data were secured from an analog simulation of a relay servo system. The results of this data were compared to the transient approach by use of the phase-plane method. The stability of the system was determined using a describing-function. The analytical approaches are described in the presentation.

A study of the effects of viscous friction is described, and the characteristic of the relay used in the system is given special attention. The response to input driving function was considered, and rise …

Transient Temperature Distribution In An Infinite Plate Subjected To Convection And Radiation Heat Exchange, Billy W. Marshall

Masters Theses

"The desired result of this paper is a method of calculating transient temperatures in an infinite plate. The resulting equations are general to the extent possible for aerodynamic heating and radiation boundary conditions. The possible methods of calculation were investigated, and it was felt that a numerical analysis presented the most feasible approach.

Numerical analysis was employed to arrive at a series of equations for calculating the temperatures at selected positions in an infinite plate. A study was then made to determine a method of solving these equations by means of some high speed computing device.

The equations were adapted …

Transient Temperature Distribution In Solid Sphere Subjected To Radiation Heat Exchange, William H. Stocklin

Masters Theses

"The author believes that numerical analysis is the most feasible approach to calculating the transient temperature distribution in a solid sphere subjected to various surface conditions; heat flow within the sphere is radial.

Numerical analysis is employed to arrive at a series of equations for calculating the transient temperature at selected points of a solid sphere. A study is made to determine a method for calculating temperatures with these equations; a computing device is found to be the most practical method for this purpose. The equations for temperatures at internal points of the solid sphere are general.

The equations have …

Effect Of Boundary Layer Control, Through Spiral Cuts, On The Film Coefficient Of Convective Heat Transfer, Nicholas W. Barre

Masters Theses

"This thesis is experimental investigation into the possibility of obtaining an increase in the forced convection heat transfer coefficient for a pipe by passing the fluid through a narrow spiral cut in the pipe.

Different spiral pipes with pitches of two, four, eight, ten, sixteen, and twenty inches were used; however, the width of the spiral cut remained unchanged at 3/16 of an inch. Several mass flow rates for water were used up to a maximum of 1536 lbs/hr for each run.

One of the objectives was to find which pitch would give the highest heat transfer rate for a …

A Study Of The Transient State Of Transpiration Cooling, William C. Wolkenhauer

Masters Theses

"This thesis is a successful attempt to show a new approach to the transpiration cooling problem. Transpiration cooling has long been known as an effective way of removing heat from porous material.

It is shown here that transpiration cooling from a porous material, assuming a temperature difference between the coolant and the porous material, is less effective than where the coolant within the pores is assumed to be at the same temperature as the material adjacent to the pore. Previous investigators made the latter assumption.

The specific problem considered here is that of a uniform, porous plate with constant physical …

Preliminary Study Of An Optimum Vibration Absorber For A Multi-Mass System With Multiple Excitation, John Raymond Burrows

Masters Theses

"The object of this thesis is to demonstrate, by the use of a modern digital computer, a fast, efficient method to eliminate or minimize undesirable stress conditions in a multimass vibrating system with multiple excitation. The condition desired is obtained by the addition of an optimum tuned and damped dynamic vibration absorber, for one critical speed only.

Maximum stress is the criteria used for design here and not amplitude as has been used previously by all other authors.

This solution requires the applied torque to be reevaluated as an average torque and a number of half integer harmonics. This method …

The Analysis, Construction, And Calibration Of An Electronic Vibrations Amplifier, Jimmie D. Howard

Masters Theses

"Vibrations analysis necessitates having a device capable of performing some initial phase of detection. The vibration amplifier presented in this thesis performs such an initial aid to analysis by detecting amplitudes of vibrations of varying magnitudes and frequencies. This is accomplished by utilizing a Piezoelectric crystal vibration pickup to obtain an acceleration wave form. Two operational amplifiers perform integrations of the acceleration to obtain displacement. A calibrated meter within the device provides a method of determining magnitudes of displacement. Recording instruments such as the Brush recorder or an oscilloscope may also be used"--Abstract, page ii.

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 …

Transpiration Cooling Of A Plane Porous Plate, Raymond George Posgay

Masters Theses

"The transient temperatures were determined in a porous plate for one dimensional heat flow and one dimensional counter coolant flow. One surface of the porous plate was heated by a hot gas by convective heat transfer. A general discussion of the problem is considered and the procedure described for working all such problems dealing with transpiration cooling.

The solution of such problems is illustrated by two examples employing a ceramic plate one inch thick and cooled by a uniform flow of air in a direction counter to the flow of heat, while one surface of the ceramic plate was heated …

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 …

Investigation Of Vertical Internal Spillways, Paul R. Munger

Masters Theses

"This investigation resulted in the development of a means of predicting the discharge of water through an internal spillway type rockfill dam. From the data obtained during the various tests, equations were developed by which the coefficient of discharge for an internal spillway type rockfill dam can be determined when the core height, rock size and head causing flow are known. The equations give results with an error of less than 5%, which is adequate for engineering works"--Abstract, page 2.

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 …

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 …

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. …

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 …

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 …
