A study was conducted to compare the competitive
ability with weeds of the short-strawed Gaines variety
wheat and taller growing varieties under different fertility
levels at three experimental locations. The
experiments were designed so that the...

This thesis presents a limited investigation of the effects
of various etches on the surface properties of silicon. Surface
recombination velocities of silicon under different etching treatments
are compared by using the photoelectromagnetic...

The purpose of the work is to enable students of botany to identify
accurately Oregon ferns, both as living plants and as dried specimens.
Therefore, it provides vegetative keys to the families, genera
and species of the ferns (Class FILICINAE)...

The approximation problem of network synthesis is considered
in four parts. First, the problem is identified. Second, the several
existing methods of solving this problem are briefly discussed. This
discussion is necessary because the well known...

This field investigation was designed to further
the understanding of the significant influence which
parent population density, as well as dispersion, have
on the dynamics of enclosed populations of the montane
vole, Microtus montanus (Peale)....

Litter site and birth weight data compiled from the
farrowing records of 275 litters out of 109 purebred
Berkshire sows of the Oregon State University swine herd
during the years 1953 to 1960 inclusive were used in this
study. Genetic and...

The external and internal morphology are considered
and important morphological characters are found which
relate Macrovelis to the family Mesoveliidae.
Both macropterous and Brachypterous forms occur
throughout the western half of the United...
