A water-soluble complex containing ergosterol together with
a component of yeast has been isolated. The complex can be isolated
from commercial yeast extract to which ergosterol has been
added or directly from whole yeast cells. The complexing agent
from yeast extract is also capable of solubilizing cholesterol and
a long...
In this thesis we consider computer techniques for inverting
n X n matrices and linear Fredholm integral operators of the
second kind. We develop techniques which allow us to prove the
existence of and find approximations to inverses for the above
types of operators. In addition, we are able to...
The three important methods of approximation; interpolation,
least- squares, and Chebyshev, are extended into bivariate approximations.
A method of obtaining polynomial approximations for very
general classes of bivariate samples is developed. Bivariate least -
square approximations are reviewed and a method of developing bibariate
orthogonal sequence is derived. A method...
The behavior of two species of stream salmonids, juvenile coho salmon, Oncorhynchus kisutch (Walbaurn) and cutthroat trout, Salmo clarki clarki Richardson, was studied in terms of the time spent by individual fish in carrying out various activities. Studies were conducted from June 1968, through May 1969, at Berry Creek, a...
This thesis reports the results of a study on the influence of biologically
stabilized kraft mill effluent (SKME) on the food relations and
production of juvenile chinook salmon, Oncorhynchus tschawytscha
(Walbaum), in laboratory streams. Experiments were conducted at
the Oak Creek Fisheries Research Laboratory, Oregon State University,
during 1967 and...
