Slavery In Colonial Massachusetts, Thomas A. Malloy Iii
Slavery In Colonial Massachusetts, Thomas A. Malloy Iii
Masters Theses
1. Introduction
The purpose of this paper is to trace the history of slavery in colonial Massachusetts. Massachusetts was by no means an originator of this institution, for the practice of slavery predates written history. Its origins probably stem from wars of conquest in which captives were used for sacrificial purposes, but as prehistoric man adopted a settled way of life, he found it practical to spare his captives' lives and enslave them. The conqueror's justification for enslavement of his captives was that he had spared their lives, and thus they were at his disposal. In a sense, one could …

Determining The Transfer Matrices Of Tapered Multiwire Transmission Lines, Clyde A. Vandivort
Determining The Transfer Matrices Of Tapered Multiwire Transmission Lines, Clyde A. Vandivort
Masters Theses
"The advent of monolithic and integrated microelectronic circuits has aroused interest in passive multilayered thin film networks. The basic thin film network is shown in Figure 1. This structure consists of alternate resistive and dielectric layers sandwiched together. Such devices are referred to as distributed parameter RC networks. The reduction of volume and increased reliability offered by thin film devices has caused considerable effort to be extended in the analysis of their characteristics....
The incremental equivalent circuit given in Figure 2 stems directly from the above physical parameters and is the circuit used as a basis for the analysis that …
Effects Of Mixing Procedure Upon Uniformity Of Fibre Reinforced Concrete, Donald E. Nortrup
Effects Of Mixing Procedure Upon Uniformity Of Fibre Reinforced Concrete, Donald E. Nortrup
Masters Theses
"This thesis describes the effects of several methods of introducing wire fibres into a concrete mix upon the uniformity of wire fibre reinforced concrete. Various mechanical and manual methods of introducing the fibres were used and comparisons of the methods were based upon variability in splitting tensile strength and the quantitative distribution of the fibres as determined by visual inspection of sawed cylinders. Test results show that the tensile strength of concrete is increased appreciably by the inclusion of steel wire fibres in the mix and the uniformity of strength is similar to that of unreinforced concrete. The methods of …

Mode Analysis Of The Unsymmetrically Fed Ground-Plane Aperture, John G. Hemmann
Mode Analysis Of The Unsymmetrically Fed Ground-Plane Aperture, John G. Hemmann
Masters Theses
"The problem of radiation from a waveguide-fed ground-plane aperture perturbed with a wedge-shaped dielectric insert was examined more carefully. The work initiated by Blumberg was continued, using a greater range of dielectric constants and smaller increments of angle.
Aperture field measurements were made over a range of dielectric constants for each wedge angle, in order to determine the change in amplitude distribution as a function of permittivity. Aperture phase measurements were also taken for selected angles. These were used with the amplitude data to predict, using numerical integration, the far-field radiation patterns of the perturbed aperture. Far-field patterns were then …
The Separation Of Optical Isomers By Gas Chromatography, Donald Ellis Carpenter
The Separation Of Optical Isomers By Gas Chromatography, Donald Ellis Carpenter
Masters Theses
"The purpose of this investigation was to study the separation of optical isomers by gas chromatography. An optically inactive solid support was coated with an optically active substrate. Racemic compounds were used as samples. The optically active packing materials tried were d-tartaric acid, d-diethyl tartrate, sucrose, d-camphoric acid, d-camphor-10-sulfonic acid, α -methyl-D-glucoside and L-(α)-glutamic acid.
Racemic compounds that were tried included 2-butanol, 3-methyl- 2-butanol, 2-methyl-1-butanol, 2-octanol, 2-bromooctane, 2-methoxy-octane, methyl-2-bromobutyrate, and 3-methylhexane.
It was found that racemic compounds could be separated by using an optically active material for packing in the gas chromatographic columns. Racemic 2-butanol, 3-methyl-2-butanol, and 2-methyl-1- butanol were …
A Study Of Film Boiling Of Liquid Nitrogen And Liquid Argon Over A Wide Pressure Range With Cylindrical Heaters, V. J. Flanigan
A Study Of Film Boiling Of Liquid Nitrogen And Liquid Argon Over A Wide Pressure Range With Cylindrical Heaters, V. J. Flanigan
Masters Theses
""A film boiling heat transfer study was conducted with three different diameter cylindrical copper heaters over a wide range of pressures for nitrogen and argon with the heat transfer surface in the horizontal position. The data were compared to the commonly used film boiling heat transfer relations. The common relations were found to be considerably in error for the range of variables covered in this investigation. A semi-empirical equation for corresponding states fluids which correlates the available data as a function of the reduced temperature and reduced pressure was derived and discussed"--Abstract, page iii.
A Comparison Of Friction And Drum Hoisting Systems On An Energy-Input Basis, Hemendra Nath Kalia
A Comparison Of Friction And Drum Hoisting Systems On An Energy-Input Basis, Hemendra Nath Kalia
Masters Theses
"The purpose of this thesis is to provide a suitable basis for comparing the relative advantages of the friction and drum hoists under various conditions of operation.
Such comparisons are mainly and necessarily based upon physical characteristics of the mechanisms for lack of appropriate economic data. It is believed, however, that this inadequacy may be alleviated to some extent by substituting comparative theoretical energy requirements of' the two hoisting systems under identical duty conditions over a practical range of mining situations involving various depths and daily productions.
This has been accomplished by adapting a computer to standard mine-hoist design techniques …
Estimation Of Regional Trends In Gravity Using Gram Orthogonal Polynomials, Stanley Dean Thompson
Estimation Of Regional Trends In Gravity Using Gram Orthogonal Polynomials, Stanley Dean Thompson
Masters Theses
"A computer program is presented which estimates the trend in a rectangular array of gravity measurements. It is assumed that the regional trend of gravity may be estimated by a low-order polynomial. The method of least-squares is applied to solve for the low-order polynomial which best approximates this trend. Gram orthogonal polynomials are used in the solution of this least-squares surface fit. The program is tested on a known polynomial and on some hypothetical Bouguer gravity data and found to approximate the ʺregional trend of gravity in these cases. The importance of eliminating any significant noise in the observations before …
Scanning Properties Of Unsymmetrically Loaded Aperture Arrays, Gary Dean Brunner
Scanning Properties Of Unsymmetrically Loaded Aperture Arrays, Gary Dean Brunner
Masters Theses
"Radiation patterns resulting from an array of waveguide-fed apertures, filled with assymmetrically [sic] cut dielectric inserts, in an infinite ground plane were investigated. The results of Blumberg and Hemmen concerning single apertures were applied to a two-aperture array, with emphasis upon obtaining an array capable of scanning in the far field through changes in the permittivity of the assymmetrically [sic] cut dielectric inserts. Scanning was shown to be possible with up to a 60⁰ scan angle with a "push-pull" method of varying permittivities, in which the permittivity of one insert is raised while the other is lowered. The aperture field …

An Investigation Of The Effects Of An Impact On Some Of The Mechanical Properties Of Aluminum Alloy 2014-T6, Rajnikant K. Shah
Masters Theses
"Static and impact tests were conducted on an Aluminum alloy 2014-T6 specimen. The purpose of this research was to determine the effects of an impact load on some of the mechanical properties of aluminum. The cross section of the specimen measured 4.438 in. by 3.850 in. and it was 12 in. long. It was equipped with a total of four electric resistance gages connected in two pairs. One pair measured longitudinal strain while the other measured transverse strain. Both gages in each pair were mounted on the opposite sides to cancel the bending effect. In the static tests, load was …
A Subsurface Geologic Study Of Petroleum Possibilities In The Pennsylvanian Rocks Of Concho County, Texas, Gregory Paul Kraus
A Subsurface Geologic Study Of Petroleum Possibilities In The Pennsylvanian Rocks Of Concho County, Texas, Gregory Paul Kraus
Masters Theses
"During early Pennsylvanian time the area now occupied by Concho County was a portion of the Texas peninsula, a broad, low arch with a karst topography developing on its exposed Ellenburger surface. A mid-Pennsylvanian marine transgression inundated the arch and it became an area of clear, shallow water deposition favorable to limestone development. Local sedimentation during Strawn time was largely controlled by its position relative to the Llano uplift and surrounding basins. A variety of subsurface maps were constructed for this study essentially utilizing electric log data. The results indicate that limestones of the Strawn platform facies rapidly change in …
Six Dimensions Of Religiosity And Riesman's Inner/Other-Direction, Edward E. Mckenna
Six Dimensions Of Religiosity And Riesman's Inner/Other-Direction, Edward E. Mckenna
Masters Theses
First three paragraphs:
To what extent do different types of religious behavior vary with different levels of inner- and other-direction?
Religious behavior is multi-dimensional in nature, with several qualitatively distinct dimensions. Hypothesized relations between different dimensions of religious behavior and inner/other-direction, together with the assumed shift from inner-direction to other-direction, have been formulated to explain the now familiar, but nevertheless controversial, religious revival in American society. This revival is controversial in the sense that it extends only to certain types, or dimensions, of religious behavior. There have been increases in church membership, identification, and ritual observance, but not in other …
Pain Elicited Aggression As A Function Of Withdrawal From Morphine Addiction, Brian G. Teel
Pain Elicited Aggression As A Function Of Withdrawal From Morphine Addiction, Brian G. Teel
Masters Theses
One branch of aggression research has concentrated on the elicitation of aggressive behavior by means of exteroceptive stimulation. Electric shock or similar painful stimuli (Ulrich & Azrin, 1962) are well known to produce fighting in the laboratory rat. This basic method has allowed experimental analysis of a wide scope of associated variables.
Ulrich and Azrin (1962) investigated several different parameters. They found that laboratory rats increased their fighting behavior as the frequency of shocks increased from 0.1 to 38 shocks per minute. With frequency fixed, the fighting response rate resembled an inverted U-shaped curve when shock intensity was increased from …
