The purpose of this study was to determine the relative resistance
of genetic lines of hops, Humulus lupulus (Linn.) to the
two-spotted spider mite, Tetranychus urticae (Koch) in western
Oregon.
Approximately three-hundred genetic lines of hops were
screened under insectory conditions during the 1965 growing season
at Corvallis, Oregon. Reduction...
Because of declines in salmon populations in recent years, the health of salmon habitat, in particular, is the focus of many resource agencies. The objective of this study is to use GIS to predict the location of suitable habitat. With data from an extensive set of stream surveys, GIS was...
During the course of ripening, Cheddar cheese frequently develops
a flavor defect described as fruity. Recent work has indicated
that the use of certain starter cultures ultimately results in the
development of the defect as the cheese ages. The flavor compounds
responsible for the defect, however, have not been elaborated....
This study was initiated in the Spring of 1966 for the purpose of
determining the present status and effectiveness of imported parasitic
wasps of the pea aphid in the Willamette Valley of western Oregon.
The pea aphid is a serious pest throughout the pea and alfalfa
growing regions of the...
It is well known that every Banach space with a Schauder basis
is separable. However, whether the converse of the above statement
is true is not known.
It is therefore the purpose of this thesis to investigate the question
of under what conditions an arbitrary, separable, Banach space
has a...
Food lipid systems are very complex and so is oxidative
degradation that render them unpalatable for human consumption.
The significance of lipid degradation and the key reactions involved
have been thoroughly studied and are well understood today. This
is not true, however, of the secondary products of the autoxidation
reactions....
