Computer oriented techniques and procedures are presented for the analysis of single and multiple cable systems. Application is made to a two-point mooring system influenced by surface and subsurface hydrodynamic loading. The effects of the various parameters are presented and the numerical method is compared to exact solutions obtained from...
The resistance of a leaf to molecular gaseous diffusion
is an important physiological response. Control of
leaf resistance enables a plant to control its transpired
water loss and regulates photosynthesis.
Four study sites representing a gradient in available
moisture and evaporative demand, were chosen in western
Oregon for the study...
An ecological study of small forest mammals was conducted
from 1964 to 1970. The objectives were to obtain chronological information
relative to the effects of current logging practices on vegetational
succession and small mammal populations.
The locale of the study was in the west-central Cascade Mountains
of Oregon. The principal...
Effects of the marine environment on age and size at maturity, early marine growth, and abundance of chum salmon, Oncorhynchus keta, were studied at Olsen Creek during 1959-77. Chum salmon returned to Olsen Creek as predominately 3-, 4-, and 5-year fish; however, age composition varied from year to year. The...
Several studies were conducted to determine the feasibility of
using terbacil (3-tert-butyl-5-chloro-6-methyluracil) postemergence
to weeds and peppermint (Mentha piperita L.). Three nonionic surfactants,
four nonphytotoxic oils, and a liquid fertilizer were each
combined with 0.5 lb ai/A terbacil in 35 gallons of water per acre.
Weed species tested include: redroot...
G. Spencer Brown's book Laws of Form has been enjoying a vogue among social and biological scientists. Proponents claim that the book introduces a new logic ideally suited to their fields of study, and that the new logic solves the problems of self-reference. These claims are false. We show that...
To determine whether a homologous neurohormone, arginine
vasotocin (AVT), can elevate the occurrence of clasping behavior in
male rough-skinned newts (Taricha granulosa), intact, sexually inactive
males were injected with either AVT or saline. The incidence
of courtship was elevated in the group of males injected with AVT,
but not in...
