An investigation into public post-secondary electronic technology programs in Texas with implications for planning
(1969)
The purpose of this study was to provide information which the Texas Education Agency could use in planning the development of electronic technology programs in junior colleges. The populations included principal employers ...
Metabolic studies on the continuously irradiated rat
(1969)
Male albino rats were continuously irradiated on a 60 R per 20 hour day schedule for 27 days and tested on days 21, 23, 25, and 27. Active transport of U- ¹⁴C glucose was measured using the inverted gut technique. Oxygen ...
An experimental comparison of programed instruction versus video-tape television in teaching selected orthographic projection concepts
(1969)
The Problem [line break] The purpose of this study was to determine the effectiveness of two variations of administering programed instruction materials for teaching selected mechanical drafting concepts as compared to the ...
The transmission of information from school administrators to teachers with particular emphasis on hierarchy of information and channels of communication
(1969)
The purpose of this study was to investigate specified characteristics regarding the flow of information from selected school administrators to selected classroom teachers. The investigation was confined to the downward ...
Excess thermodynamic properties of the binary liquid system 2-butanone-ethylene glycol
(1969)
The excess thermodynamic properties of the binary liquid system, ethylene glycol-2-butanone, have been determined at 25°C. The excess Gibbs free energy has a maximum value of 329 cal. mole⁻¹ at 0.525 mole fraction of ketone. ...
The development of an experimental criterion program for industrial education
(1969)
The Problem [line break] This research was to develop an experimental criterion program technique of teaching for Industrial materials and to implement the program in a course, Industrial Materials and Manufacturing ...
The effect of ionizing radiation on selected chemical, physical and microbiological characteristics of egg white proteins
(1969)
The effect of gamma radiation on selected chemical, physical and microbiological characteristics of three egg white proteins have been studied. Lysozyme, ovalbumin and conalbumin substrates were extracted from egg albumen, ...
A study of the validity and reliability of the twelve minute run under selected motivational conditions
(1969)
The purposes of this investigation were (1) to determine the validity of the twelve minute run under each of four selected motivational conditions; (2) to determine the validity of the twelve minute run under all conditions ...
An analysis of the time interval distribution of neutron pulses from a nuclear reactor
(1969)
Neutron pulses as detected by a BF3 counter located in the center of an AGN-201 reactor were analyzed concerning their time behavior with the objective of ascertaining the feasibility of an on-line determination of the ...
A study of residual stresses in a weld with one free surface
(1963)
The distribution of residual stresses in a multi-pass weld with one free surface was evaluated by X-ray diffraction techniques. It was determined that for specimens fabricated from the same materials in approximately the ...
