Study Of Fission Neutron Spectra With High-Energy Activation Detectors, James A. Grundl

Physics & Astronomy ETDs

The energy spectra of neutrons from the fission of U235, U233, and Pu239 have been studied with seven high-energy activation detectors covering the range 0.6 to 16 Mev. Interpretation is in terms of the Maxwellian spectral function E^1/2 exp(-E/T). By means of a unique cavity arrangement within a moderator to obtain pure thermal-neutron-induced fission neutrons, the average energies of the three spectra are found to be in the ratios

U235: U233: Pu239= (1): (1.016+or-0.003): (1.039+or-0.003).

Differences between the normalized spectra are most pronounced at high energies as exemplified by the relative Pu239:U235 flux ratios 1.17+or-0.013 for 611 Mev.

An Investigation Of Steric Inhibition Of Resonance In Liquid Scintillators, Richard L. Taber

Chemistry and Chemical Biology ETDs

It is well known that the replacement of two or more of the ortho hydrogen atoms in the benzene rings of biphenyl by lager atoms or groups hinders the rotation about the l.l'-carbon single bond in the biphenyl system. If the groups are so large that they are unable to pass each other upon rotation of the l,l'-bond, then the two benzene rings are forced to assume a non-planar configuration.

Review Of The Physical Aspects Of Osmotic Pressure, Joseph F. Goffaux

Physics & Astronomy ETDs

It should be mentioned that this paper deals mostly with the work done by others and only a certain portion is original. The student wishes to state that he is presenting a thesis that would be considered theoretical and not empirical. The history of the work done in the field of osmotic pressure is treated at length and much of the theory used by the experimenters is derived. Many periodicals carry the papers written by the scientists of osmotic pressure and some of these men have spent perhaps fifteen of twenty years on their experiments.

A Theoretical And "Experimental" Investigation Of One-Dimensional Molecular Distribution Functions, Samuel Blackman

Physics & Astronomy ETDs

The presence of long range forces and of various types of boundary conditions may be expected to cause deviations from the well known Maxwell-Boltzmann velocity distribution, resulting in a spatially dependent velocity distribution. One possible method for obtaining a theoretical spatially dependent velocity distribution is to attempt an approximate solution for Liouville's equation. This is done in this thesis. The effects of a long range repulsive force inversely proportional to the interparticle separation as well as the effects of three types of wall boundary conditions upon the velocity distributions of a one-dimensional set of ordered particles have also been investigated …

Transistorized Circuits For Telemetry, Dominick Misciascio Jr.

Physics & Astronomy ETDs

This thesis is concerned with the telemetry of small DC signals from photomultiplier tubes. The circuitry must have a high input impedance so as not to load down the photomultiplier tube and a low output impedance which is capable of controlling the current through a small incandescent bulb. This bulb is used to illuminate a photoresistor. The output of the circuit consists of a variation of the resistance of the photoresistor. This variable resistance is conventionally converted into a variable audio frequency which is transmitted to the receiving station on a radio-frequency carrier. The output resistance must be independent of …

A Radio Frequency Power Oscillator And Impedance Matching Device., Charles D. Preston

Physics & Astronomy ETDs

Certain molecules, called “globular” molecules, when first solidified form what are called “plastic” crystals. They are called “globular” either because they may exhibit an approximate spherical symmetry about their center of structure or because they may be small enough or of such a shape as to appear spherically symmetric because of rotation. The first case might be exemplified by methane (CH4) which has the configuration of a regular tetrahedron. The second case might be exemplified by hydrogen chloride (HCL).

A Transister Quenching Circuit For Geiger Counter Tubes, Andrew M. Simko

Physics & Astronomy ETDs

This thesis attempt to provide a solution to a basic problem inherent in the operation of Geiger-Mueller counting tubes, that is, reduction of the insensitive time, or “dead time”, following the discharge. Many researchers, using various quenching gases for internal quenching and various vacuum tube circuits for external quenching, have succeeded in reducing the “dead time” significantly. Reduction of the insensitive time provides more efficient and accurate counting. The solutions presented in this thesis utilize transistor circuits instead of vacuum tube circuits for external quenching. In an extensive research of current literature, no attempts to transistorize a quenching circuit could …

The depth of the alluvial fill in the area is not known. The channel is 50 to 300 feet wide with braod meanders interspersed with straight reaches. The Rio Puerco is ephemeral in the lower reaches with flow produced by local rains on the watershed.

Petrography Of The Olalla Stock, Okanagan Mountains, British Columbia, James Anton Sturdevant

Earth and Planetary Sciences ETDs

The Olalla stock is located in the Okanagan Mountains of south-central British Columbia, about 20 miles north of the international boundary. It occupies approximately 6 square miles and consists of late Mesozoic mafic and ultramafic rocks and subordinate alkalic rocks, which have intruded previously folded and metamorphosed sediments of the Triassic (?) Shoemaker Foundation.

The rocks of the stock may be broadly grouped into two major categories: (1) those formed from the differentiation of a crystallizing magma that probably entered during the Nevadan orogeny, and (2) those formed by metasomatic replacement of pyroxenite. The rocks of the first category are, …

Convergence Functions And Their Related Topologies, Darrell C. Kent

Mathematics & Statistics ETDs

A convergence function is a correspondence between the filters on a given set S and the subsets of S which specifies which filters converge to which points of S. This concept is defined to include types of convergence which are more general than that defined by specifying a topology on S. Thus a convergence function may be regarded as a generalization of a topology.
