The Mimulus washingtonensis complex is a group of morphologically similar
species centered in the Pacific Northwest. All are rare, and most are under
consideration for listing as endangered. Morphometric and pollination data were
used in developing a revised taxonomy for the group. Five species and two varieties
are recognized. Mimulus...
Capillary pressure-saturation data obtained for unconsolidated porous media with different liquids are examined to investigate the effects of clay-liquid interactions on liquid retention. Liquid retention functions are assumed to reflect the effective pore-size distributions. The hydraulic variables, capillary pressure and saturation, are transformed to account for changes in liquid retention...
This study was designed to reveal the outcomes of participation
in science project activities such as Science Fair projects among
ninth grade science students in Multnomah County, Oregon, during
the second half of the 1963-1964 school year.
A stratified sample of five public schools was selected to participate in this...
The purpose of this study was to investigate the relationship
between kindergarten experience and fine-muscle eye-hand coordination
abilities of first grade children.
The subjects were 181 first graders in the public schools of
Albany, Corvallis, and Salem, Oregon. The mean age of the sample
was 76.69 months with a standard...
The differential cross section for the reaction k⁻+p[forward arrow] k⁰+[uppercase xi]⁰ was measured in a spark chamber experiment for an incident k⁻ momentum of 1.8 GeV/c. The target was liquid hydrogen confronted
by an anti-coincidence counter to insure neutral particle production.
A 60 element hodoscope signalled the presence of four...
A unique aspect of this study is that it involves an unusually
large number of individuals of American Indian descent. The sample
population was composed of those Indian members of the 1962 high
school graduating class from a six-state area. The selected graduates
came from local public, Bureau of Indian...
A series of 8 experiments was conducted to investigate various
methods of delaying the sexual maturity of developing White Leghorn
(W. L.) pullets grown during a period of increasing day length and to
control the feed intake of W. L. layers. In the first five experiments
W. L. pullets were...
