This study compares the production rates and yarding costs of prebunching
with a low investment skyline yarder and swinging with a larger
skyline yarder to full-cycle thinning with the larger yarder The study
analyzes two slackpulling techniques (manual and haulback assisted) and
two carriages (a multi-span carriage and a clamping...
The purpose of this study of the life and career of Dr. Carl
Leonard Anderson was to recount his professional contributions to
the field of health and relate these to public health and health education. The major emphasis of this study concerned Dr. Anderson's
professional life.
The accomplishment of the...
The objectives of this study were to establish a suitable method
for the measurement of the root cation-exchange capacity of conifer
seedlings, and to examine possible influences of this root characteristic
on nutrient absorption from a Bellpine soil under greenhouse
conditions.
The exchange sites of fresh, excised roots were saturated...
The causes of turbidity in impounded and released reservoir
water are studied. Seven Willamette Basin reservoirs are compared
to isolate watershed and reservoir characteristics which produce variations
in turbidity. Of the seven, Hills Creek Reservoir is examined
in detail. Particular features of the basin and impoundment are
studied to isolate...
Theoretical studies and experimental results are presented for the rotational motion of molecule's in crystalline solids. The group theory is solved for molecules of any symmetry matrix isolated at a site in a crystal field of any symmetry. As the potential terrier to rotation of the molecule relative to the...

While the primary emphasis of this study was on the professional
aspects of a business teacher's preparation, by necessity it was
concerned with other aspects of the preparation of business teachers,
especially as these relate to the so-called "professional sequence."
Thus the purpose of the study was to seek...
Various methods of presenting and mathematically describing particle
size distribution are explained and evaluated. The hyperbolic
distribution is found to be the most practical but the more complex
characteristic vector analysis is the most sensitive to changes in
the shape of the particle size distributions.
Particle size distribution, nutrient concentrations,...
Phenetic relationships in insular populations of Lacerta sicula
and L. melisellensis correspond to geologic ages of the islands in two
regions of the Adriatic Sea. Populations of L. melisellensis on older
islands are more similar to populations of L. sicula than are L. melisellensis
from younger islands, and examination of...
