Tile drainage increases aeration in the root zone of poorly drained soils by
accelerating water movement from the subsurface. Water movement is the main agent
of chemical transport, either transporting soluble materials directly (e.g., nitrate) or by
transporting the soil particles that bind adsorptive compounds (e.g., pesticides). The
detection frequency...
"Fifty years after the pioneering work of McCulloch and Pitts, the study of neural nets is alive and active. In this paper, I have discussed some of the work that is of current interest to me and my co-workers. I would, perhaps, be remiss if I failed to mention some...

The abundances of 12 elements, Fe, A1, Na, Ni, Cr, Mn,
Co, Ca, Sc, Ir, Sm and Eu have been determined by INAA in 61
individual chondrules (0.1-100 mg) separated from five Allende (C3)
meteoritic fragments ( 25g). Ti and V have been determined in 18
of these chondrules, and...
We report ²⁷Al and ⁶⁹,⁷¹Ga impurity and ⁶⁷Zn host species NMR experiments on
ZnO powders containing Al or Ga dopants in the range 0.03 to 3 at. %. Spectral
analysis of the ⁶⁷Zn and ⁶⁹Ga quadrupole powder patterns indicate gallium is
substitutional for zinc and the electric quadrupole coupling of...
Immunity in juvenile coho salmon (Oncorhynchus kisutch) was
evaluated after immunization against vibriosis by parenteral, oral or
immersion methods. Relative levels of immunity were determined by
protection of fish from experimental water-borne challenges with
Vibrio anguillarum and by serum agglutination titers. Coho salmon
eggs were exposed to bacterin during artificial...
The purpose of this study was to determine the effectiveness of an in-service project for teachers of the social studies (K-12). The project was sponsored by the Region II Committee of the Oregon Council for Curriculum and Instruction (O.C.C.I.) during the period from November 1, 1966 to April 1, 1969....
Pre-harvest sprouting in wheat costs farmers millions of dollars every year. Pre-harvest sprouting tolerance (PST) has minimized this problem, but improvement of PST is still necessary. Synthetic hexaploid wheats (synthetics) have been used as sources of
genes coding for many useful traits. Two studies evaluated the PST of a synthetic...
A diallel cross consisting of ten parents was grown on the
Hyslop Agronomy Farm near Corvallis, Oregon, in order to obtain
estimates of the gene action contributing to yield and its components
in wheat. Gene action estimates were obtained by two methods of
diallel analysis and from narrow sense heritability...
