Although soil tillage has been used successfully to alleviate compaction of forest soil after logging in a number of management contexts, little is known about the feasibility of tilling in residual stands. In an attempt to weigh the benefits of tillage against possible damage done to residual trees during tillage,...
The northern Los Angeles basin is influenced by two structural styles: the west-trending compressional Transverse Ranges to the north, and the strike-slip Peninsular Ranges to the south. The interaction of these two structural styles has resulted in a complex fold fault belt at the northern margin of the Los Angeles...
Excessive growth by red clover, Trifolium pratense L., grown for seed
interferes with maximum seed production and harvest in Oregon's Willamette Valley.
This study was conducted during 1986 and 1987 on red clover cv. Kenland to
determine if plant height and dry matter production could be inhibited and seed yields...
In a conventional well-mixed fluidized bed the solids are almost
completely mixed and the residence time for individual particles may vary
between zero and infinity. For materials especially sensitive to the processing
time, a wide distribution of residence time is extremely undesirable. A multi-compartment
fluidized bed was proposed to minimize...
The study of the social dimensions of Shakespeare's art is represented by the work of Mikhail Bakhtin, C.L. Barber, Robert Weimann, Edward Berry, and Michael Bristol. Their work analyzes the background in Elizabethan social practices and popular dramatic traditions that contribute to the form, structure, and meaning of Shakespeare's comedies....
The Asian noodle market is responsible for the increased volume of wheat
imported to that region in recent years. Soft white wheat produced in the Pacific
Northwest is mainly used for baked products, whereas an Australian wheat,
Australian Standard White, is preferred for noodles. To enter this market soft
white-wheat...

Zora Neale Hurston was a Black American writer
during the period of the Harlem Renaissance. The
purpose of this study is to show that three of her four
novels form a protracted discussion of a particular
type of freedom which was of especial interest to
Hurston. The study seeks to...
Abraham Heschel wrote that a philosopher's primary task was not merely to describe and judge the modes and facts of actual human behavior, but also to examine and understand the meaninq of those descriptions and judgements of modes and facts (Bella, 1978). Our values are critically tied to our structures...
Sod-seeding techniques offer graziers a convenient way to introduce superior grass cultivars into underproductive permanent pastures. Production loss and erosion are minimized. In conjunction with improved grazing management and fertilization, renovation can significantly improve yield and quality of pastures. Existent vegetation must be suppressed prior to introducing new cultivars. This...
This paper provides logit estimates of the probability that students will
cheat in a specific class using randomized response and direct question data in
two logit models. The results predict that there are several indicators of the
probability of cheating occurring in a class. These factors include both student
and...
The solution of coupled neutronic/thermal hydraulic nuclear reactor calculations
requires the treatment of the nonlinear feedback induced by the thermal hydraulic
dependence of the neutron cross sections. As a result of these nonlinearities, current
solution techniques often diverge during the iteration process. These instabilities arise
due to the low level...
Detailed subsurface structure contour maps and cross sections have shown the
northern Los Angeles basin to be underlain by a south facing monocline that is
complicated by secondary faults and folds. The monocline forms a structural shelf that
marks the northern boundary of the Los Angeles central trough. The monocline...
