Farmers and researchers are aware of spatial variation in
grain yield within farms or fields. Fertilizer management may be
improved if techniques can be developed to identify grain yield
variations in wheat fields. Aerial color infrared (CIR)
photography was used to identify winter wheat (Triticum aestivum
L.) canopy biomass variability...
Peas (Pisum sativum) are an important constituent in the diet
of many people. Peas may be cooked and eaten as green peas shortly
after harvest, stored for short periods in the pods, or, after suitable
treatment, stored for long periods before consumption. Many factors
influence the yield and quality of...
The purpose of this study was to investigate the household tasks that
school-age children perform and the average amount of time spent performing
those tasks. The sample included 219 children in 135 families
taken from the Oregon sample of 210 families interviewed for the Northeast
Regional Research Project 113: "An...
It has long been observed that stress can increase our
susceptibility to infectious diseases and cancers. Recent
experimental evidence suggests that this increased susceptibility is
due to suppression of immunity. A variety of neuroendocrine products
are released during periods of stress, and a large number of these
are now known...
The parameters of separable coupled channels s-wave potentials for the strong
KN interaction are determined from low energy K⁻p scattering data with
additional constraints from π⁻p π∑K° production data. The shifts and
widths of the Coulomb bound states in kaonic hydrogen are calculated with
these potentials and compared with experiment....
In February 1905 the Oregon State Academy of Sciences formed in
Portland to promote scientific research and diffusion of scientific
knowledge in Oregon. The founders also planned to assist in the
discovery and development of the state's natural resources. The
Academy was the first scientific society in Oregon with professional...
During the years between 1930 and 1950 a number of attempts
were made to introduce techniques and ideas from cytology,
ecology, and genetics into the field of taxonomy. Advocates of
this "experimental taxonomy" believed that cytological, ecological,
and genetic techniques would provide a rigorous, objective
methodology to replace the traditional...
