Examination of polished sections of manganese micronodules
from metalliferous sediments from the Bauer Deep reveals sequences
of ferromanganese deposition which are consistent for micronodules
from a single sediment sample and imply a common depositional
history for members of such assemblages. The relatively simple
'stratigraphy' of manganese micronodules, as compared to...
This research project is an historical case study of the conflict
which evolved from the deliberations and subsequent implementation
of bilingual education in Central School District 13J, Independence,
Oregon. The time period under consideration spans 35 months,
beginning in August 1974, when district officials first proposed bilingual
education, and ending...
An understanding of the dynamics of individual tree and stand
growth, development, and structural patterns during the immature
formative years of a commercial species is essential to determine
correct thinning practices necessary to attain desired objectives.

Pacific madrone, tanoak, and California black oak are the most economically promising native California hardwoods. Volume and value data indicate upward trends in growing stock levels and prices received for their products. These trends are likely to continue. They suggest research is particularly needed for: (1) seed fall and
regeneration,...
Fuel loading patterns which have a minimum power peak are
economically desirable to allow power reactors to operate at the highest
possible power density and to minimize the possibility of fuel
failure. A computer code called SHUFLE was developed for pressurized
water reactors which shuffles the fuel in search of...
Most technological problems associated with man-machine conversations
have been solved and are well documented in both the
contemporary technical and lay literature. The major remaining
