Johnston, D. C.; Silbernagel, B. G. – Amer J Phys, 1969
Describes modifications of a commercially available strip-type transmission line, which makes possible reproducible measurements of standing waves on the line. Experimental data yield values for the characteristic impedance, phase velocity and line wavelength of radiation in the transmission line, and the dielectric constant of material in the…
Descriptors: College Science, Electricity, Instruction, Laboratory Equipment
Shepard, Herbert A. – J Appl Behav Sci, 1970
Changing culture requires interventions invalidating old processes and conditions that facilitate the creation of new self validating processes. The personal growth laboratory becomes a temporary system of new self validating processes. Prepared for a conference on Intensive Small Group Process sponsored by Foundations Fund for Research in…
