There is a lack of available information concerning availability,
usability and utilization of school-owned land in western Oregon,
southwestern Washington and northwestern California. It would be
helpful to know if land is available for agricultural use, how it is used,
and ways that it can be used to give experience...
Electrical resistivity and thermoelectric power measurements
have been made over the temperature range of 450° to 600°C on
n-type liquid thalliurn-tellurium solutions. Liquids with compositions
from 61.5 to 72.0 atomic percent thallium were studied. In addition,
alloys of some of the three component thallium-teIlurium solutions
containing small amounts of silver,...
Density measurements of molten solutions of thallium
and tellurium have been made over the temperature range
220 to 650°C and the composition range 31 to 69 atomic

over wide ranges of temperature and composition...
The longitudinal magnetoresistance of single-crystals of
mercury is investigated experimentally, both in the low field and
the high field regions. The variation of the magnetoresistance with
crystal purity, orientation, size and temperature below 4.2°K is
presented. In the low field region the data are discussed in terms
of existing theory....
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
