at home and with local off-farm agricultural business...
A facile route to bicyclo(2.1.1)hexanes was developed involving
the intramolecular photocyclization of 1, 5-hexadien-3-one to
bicyclo(2.1.1)hexan-2-one. A study of the chemistry of bicyclo-(2.1.1)hexan-2-one was undertaken. Deuterium exchange and borohydride
reduction demonstrated the strain present in the ketone.
Further evidence was obtained from the failure to introduce substituents
alpha to the...
Internship and field experience programs have been used to
prepare educators for roles in public school teaching and administration;
junior college and university teaching, and adult education.
Based on a survey of the literature it is apparent that little attention
has been given to the role that these internship and...
The major purpose of the study was to determine whether
science process achievement tests could be developed for administration
to groups of primary grade students. Six Basic Science Process
Tests (BSPT) were constructed as samples of the format proposed.
Each BSPT was designed to assess one of the basic science...
The Columbia River Gillnetter is the pilot of the Lower Columbia River commercial fishing industry, keeping fishermen and the public in touch with today's important issues.
