A potato plant growth and production model is developed with
the objectives of analyzing management alternatives and exploring
the nature of the early dying syndrome. The geographic area of
focus was the centerpivot irrigated circles of Oregon's Columbia
Basin. A problem analysis of the potato production system of this
area,...
A special case of a parallel multiprocessor scheduling (MP) problem
is investigated. A set of jobs with a known process time and a.resource
requirement is scheduled on machines controlled by processors,and
the total changeover cost between jobs is to be minimized. Each processor
may control up to two machines and...
In response to the growing preference for the small family, this study was carried cut to acquire information about women who expect zero, one, or two children. The purposes of the study were: to identify the cultural and socioeconomic characteristics of these women; and to determine which of these characteristics...
This study was designed for the purpose of expanding knowledge
of the correlates of role-taking as measured by Feffer's Role-Taking
Task. The variables of perception, sex, age, reading achievement,
and ordinal position were investigated. The perceptual variables
measured were visual memory, field dependence/independence,
auditory memory, and organizing and synthesizing ability....
Systems theory and role theory were used in this study to
develop a management model, integrating the managerial and
psycho-social subsystems of the family system. The integrated theory
and model were used to derive hypotheses concerning whether or not
type of task and actual/relative amount of time spent on household...
The lipid composition of plasma membranes of corpora
lutea was examined to determine whether changes in this
organelle occur during regression and early pregnancy in
the ewe. Forty ewes were assigned to be necropsied on
days 13 or 15 of the estrous cycle (D13-NP and D15-NP) or
pregnancy (D13-P and...
Coho salmon (Oncorhynchus kisutch) migration and spawning are unique components of the salmon life cycle because they require synchrony of behavior with other individuals as well as with acceptable fluvial conditions. As with other organisms that exhibit group mating behavior, it is likely that environmental cues trigger coho salmon movement...
The purposes of this study were to investigate patterns and causes of weight loss among
elderly long-term care residents and to examine the relationship between weight changes
and the nursing home survival. The study was designed to accomplish five objectives: 1)
to examine the rate and degree of the first...
