Easter Island and Sala y Gomez are part of the Sala y Gomez
Ridge, a broad band of high topography and scattered seamounts
extending ESE from the East Pacific Rise. It has been proposed that
the Sala y Gomez Ridge results from the movement of the Nazca Plate
over a...
Nut drop in the filbert is a consequence of the senescence of the
husk. It is possible to accelerate this process by the application of
ethephon (2-chloroethyl)phosphonic acid after the nut has abscised
from the base of the husk. This study is an investigation on the physiological
effects of the...
A taxonomic study of the genus Ophionectria Saccardo is presented.
The genus is described and the only remaining species, the type species,
Ophionectria trichospora, is described and figured. Ophionectria
trichospora is compared with Nectria haematococca to define relationships
between the two genera.
All other species formerly placed in Ophionectria are...
The equations of motion of an elastic cable suspended in a
viscous medium from two arbitrary points are derived. These are
then linearized for the undamped, inextensible case, and it is found
that the equations describing the in-plane motion of the cable are
then independent of the equation describing the...
In this dissertation we construct a homology theory on the category of submersions which generalizes the homology of the base space with coefficients in the homology of the fiber as given by the E²-terms of the Serre spectral sequence of a fiber bundle. The main motivation for this new homology...
The equations of motion of a suspended, inextensible cable in
the absence of damping are studied. A method is developed and
illustrated for determining the frequencies and mode shapes for small
oscillations about the equilibrium configuration.
With the introduction of a new variable, the fourth order equation
governing tangential displacement...
Cambial activity was studied in trees infested by the balsam
woolly aphid and in non-infested trees of grand and subalpine fir.
Infested and non-infested samples of grand fir were collected near
Corvallis during 1968 and 1969. Samples of subalpine fir, noninfested
and infested, were collected near Odell Lake, at approximately...
