Purposes of the Study: 1. To design an instrument for classification of
teacher-child verbal interaction formulating classroom
cognitive patterns of communication.
2. To use the designed instrument in a classroom
outside the pilot program to formulate an apparent
teacher-child cognitive pattern of communication. Securing and Treating the Data:

New syntheses for 2-bicyclo(3.3.1)nonanone and 7-bicyclo-(3.3.1)nonen-2-one were developed. The saturated ketone was prepared
from phenol and acrylonitrile via a novel intramolecular
S[subscript N]2 cyclization process. A Friedel-Crafts cyclization of 3-(3-cyclohexenyl)propanoyl chloride permitted synthesis of the unsaturated
ketone from 4-cyclohexene carboxaldehyde. The formation of
the bicyclo(3.3.1)nonane rather than a bicyclo(3.2.2)nonane skeleton...
Active transmission lines, a generalization of classical transmission
lines, are useful electrical devices. They can be utilized to
realize distributed amplifiers and to obtain other electrical characteristics unattainable with passive lines. Active lines have historical
significance and model many physical processes including heat
conduction in an internally heated material, a...
Indentation hardness tests were made on sections of 211 pieces
of Douglas fir and 208 pieces of Western hemlock at a moisture content
of about 11 percent. Specific gravity and visual-density evaluations
were also determined.
Correlation coefficients for linear regression of density, as
measured by specific gravity, on average standard...
