Secondary Reactions And Partial Rate Factors In The Sulfonation Of Chlorobenzene And Toluene, Ernest Arthur Brown
Secondary Reactions And Partial Rate Factors In The Sulfonation Of Chlorobenzene And Toluene, Ernest Arthur Brown
Theses and Dissertations
The sulfonation of chlorobenzene, chlorobenzene-benzene, and toluene-benzene mixtures by sulfur trioxide in liquid sulfur dioxide at -12.5° C. was studied to obtain isomer distribution and relative rate data. The isomer distribution for the reaction on chlorobenzene was determined by an isotope dillution technique. Relative rate experiments were conducted by sulfonating C14 labeled benzene in competition with nonradioactive chlorobenzene and toluene and the count rate of the products was used to determine product composition. Ultraviolet spectrophotometry was also used to investigate variations in isomer distributions as a function of sulfur trioxide concentration. The apparent relative rates of sulfonation (kX/kB) as calculated …

Five by seven inch black and white photographs were shown to thirty patients and thirty registered nurses. The subjects were controlled in regard to sex, race, residence, language, and physical and emotional orientation. They were asked to focus upon the photographed nurse's touch and to tell in one or two words what meaning they felt that the nurse was trying to convey to the patient by her touch. Responses were recorded …
Conductive Sphere On A Charged Conductive Plane, Birney Robert Fish
Conductive Sphere On A Charged Conductive Plane, Birney Robert Fish
Masters Theses
Statement of the Problem: If a conductive sphere is placed in contact with a semi-infinite, conductive plane, the configuration constitutes a three-dimensional equipotential surface. Assuming an isolated plane to be electrically charged to a known surface charge density (σ°) originally, it is desired to determine the effect produced by placing a sphere on the plane. Specifically, the purpose of this investigation is to determine the force exerted on the sphere normal to the plane, the total charge acquired by the sphere and the perturbation in the electrical field due to its presence on the plane.

Evaluation Of The Dispersion Relations Of Photoproduction, Paul Finkler
Evaluation Of The Dispersion Relations Of Photoproduction, Paul Finkler
Paul Finkler Papers
A modification of the Omnes method is used to solve the singular integral equations for the 3-3 partialwave amplitudes of photoproduction. The effects of multipion production are assumed to be negligible. The method requires a knowledge of the phase at all energies. Consequently, it is necessary to treat the corresponding pion-nucleon scattering problem to determine the eBect of the high-energy behavior of the phase on the solution for the scattering amplitude at low energies. The sharply resonant nature of the problen suggests an approximation in the form of solution, rather than in the Born terms, which leads to relatively simple …
Anion Contributions To The Electrical Conductivity Of Alkali Chlorides, Robert Fuller, M.H. Reilly
Anion Contributions To The Electrical Conductivity Of Alkali Chlorides, Robert Fuller, M.H. Reilly
Robert G. Fuller Publications
The measured electrical conductivity of pure RbCl is separated into the usual anion and cation contributions with activation energies of 2.55 and 1.58 eV, respectively. By comparison with corresponding results for KC1 and NaCl it is found that the alkali-chloride anion and cation activation energies differ most for nearly equal anion and cation radii. We conclude from this anomalous trend that an extension of conventional theory is required.

Water Resources Of Tacoma, Washington, Richard Martin Glaser
Graduate Student Research Papers
This study explores the fresh water and hydroelectricity resources of the City of Tacoma, Washington. The history and development of the water supply and hydroelectric facilities is examined. One can see that the development of the water resources has been directly affected by the growth in population and industry and that the nearness to the city of development sites has been an aid in this development. With the amount of water available at present and the increase in hydro-electric facilities during this decade, the future outlook for Tacoma in the field of water resources seems bright.

A Study Of The Effects Of Dredging And Dredge Spoil Disposal On The Marine Environment: Project Report., Virginia Institute Of Marine Science
Reports
The Rappahannock Shoal and spoil disposal area investigated encompasses an area of approximately 180 square miles. The initial sampling program (1961) consisted of the establishment of a series of transects across the survey area. One hundred sampling stations were located along the established transects.
Inasmuch as the texture of the bottom sediments varied distinctly from place to place within the mid-bay region, the initial objective was to delineate the sediment distribution. Ninety-eight core samples were taken from the area with a modified Phleger coring device and analyzed in detail for textural characteristics. Representative stations were chosen and core samples were …

F Band In X- And Electron-Irradiated Caf2, David A. Patterson, Robert Fuller
Robert G. Fuller Publications
This Letter reports an investigation using pulsed electron irradiation to determine if the low efficiency of F-band coloration in calcium fluoride is caused by the instability of the F center. No transient F centers were seen in times as short as 2 x 10-7 sec. It is concluded that the inherent efficiency of F-band coloration in CaF2 is small compared with similar processes in alkali halides and a possible reason for this is discussed. Calcium fluoride has been extensively studied and is found to be more difficult to color than alkali halides and to have absorption …

Inelastic Collisions Of The Second Kind Between Electrons And Excited Mercury Atoms, Paul Burrow
Inelastic Collisions Of The Second Kind Between Electrons And Excited Mercury Atoms, Paul Burrow
Paul Burrow Publications
The relative cross section for inelastic collisions of the second kind between electrons and mercury atoms in the excited 3P1 state was measured as a function of electron energy. Excited atoms were produced by absorption of the 2537 Å resonance line from a mercury arc. A low-energy beam of electrons was produced using the retarding potential difference method. Scattered electrons which gained kinetic energy were detected by passing them through a potential barrier which reflected unscattered electrons. The data are in good agreement with the cross section computed by applying detailed balancing to the known cross section for …

An Introduction To The Fundamentals Of Radiation Transport Theory., William A. Proctor
Physics & Astronomy ETDs
I first became interested in radiation transport theory when, in August 1966, I was given primary responsibility for a large computer program which serves as a tool for solving high temperature, time dependent, radiation-hydrodynamics problems. Inquiries as to where to start learning about this subject invariably resulted in my being directed to the two books by Chandrasekhar (1957 and 1960) and the book by Kourganoff (1963). From the beginning of my study of these expositions, I found it rather curious that a theory which treated the radiation field as continuously distributed in space was formulated in a manner which appeared …
Nuclear Quadrupole Relaxation., Derwin F. Brown
Nuclear Quadrupole Relaxation., Derwin F. Brown
Physics & Astronomy ETDs
A nucleus with an asymmetric charge distribution (an asymmetric arrangement of protons) exhibits a quadrupole moment which interacts with the gradient of the electric field of the surrounding electrons. The interaction energy is a function of the angle between the nuclear spin axis and the axis of the surrounding electric field. The nucleus processes about the electric field axis in quantized energy states. These quantized energy states correspond to a hyperfine splitting similar to the hyperfine structure of the magnetic dipole-dipole interaction between the nucleus and the electrons. The application of an external electric field, oscillating at the processional frequency …

A Qualitative Study Of The "Bohlmann Band", John Alfred Richman Jr.
Master's Theses
This thesis is concerned with a qualitative study of the "Bohlmann Band", a result of C-H stretching frequencies, which is often observed in the 3.57 to 3.70 μ region in the infrared absorption spectra of amines. The appearance of this band is characteristic of tertiary amines although a few exceptions have been encountered.
