3-Methyl-2,4-dioxabicyclo [3.3.1] nonane and 7-hydroxy-3-methyl-2, 4-dioxabicyclo [3.3.1] nonane were synthesized by the
method of Croxall, Glavis and Neher, although in low yields.
The structure of both compounds was proven by analytical
methods and analysis of their spectral properties.
Tentative configuration of C-3 in both compounds was
assigned on the assumption...
Nomia melanderi Cockerell is one of the most efficient pollinators of alfalfa in Eastern Oregon. Emergence begins in June, usually reaches its peak in early July, and may continue into early August. Male emergence precedes female emergence by four or five days. For the first few weeks of this time,...
Three seismic refraction profiles obtained between 42°N and
43°N along the median valley of the Gorda Ridge, an active spreading
center, allow the computation of the velocity structure underlying the
valley. Wide angle reflections which appear on the seismic records
suggest the existence of a velocity inversion underlying layer 3...
Presenting and synthesizing several paradigms for the teaching of literature in American colleges, I investigate how definitions of reading, readers, texts, interpretations, and knowledge affect student acts of reading and writing. In addition, I draw upon specific examples of text-based, reader-based, and social-cultural based models for the teaching of reading...
Thirteen New World populations of Megachile rotundata and M. apicalis and
two Old World populations of M. rotundata were analyzed at 23 enzyme loci using
cellulose acetate electrophoresis. Conventional and G- or C-banded karyotypes were
also examined in these populations. The principal findings are (1) No differences
were found in...
This study compares the results of a contingent valuation (CV) mail survey and the voting outcome of a bond measure to fund improvements, through property tax increases, to a downtown park and adjacent riverbank in Corvallis, Oregon. In addition to asking survey respondents about their voting decision, respondents are presented...
The purpose of this study was to determine and explain
attitudes toward intercollegiate athletics of undergraduate
students in three academic majors attending Oregon State
University.
The attitudes of a proportionate random sample
consisting of 215 students were measured according to their
responses to thirty-two Likert scale items containing six
sub-scale...
The dynamics of stands in the mid-elevation old-growth
Douglas-fir (Pseudotsuga menziesii) forests of the central western
Oregon Cascade Range were investigated using stand structure
analysis. Trees with different growth rates were commonly present
in the same stand, which resulted often in a weak correlation
between tree diameter and age. Thus,...
Phospholipids of Tenebrio molitor larvae were
separated on columns of DEAE-cellulose and silicic acid-Hyflo Super Cel. The major phosphatide components were
identified by various analytical procedures.
Phosphatidyl choline was demonstrated to be the
predominant phospholipid with a high percentage of
phosphatidyl ethanolamine. A small amount of inositol-containing
phosphatides were present....
