In attempting to provide modern water and
sewerage services to the non-indigenous inhabitants of
Canadian Arctic communities, engineering modifications are
necessary owing to the presence of a continuous permafrost
zone and a severe climate. Modifications are constraints
on communities in that the costs of providing water and
sewerage services are...
In 2011, a study by Freeman and Wornell uncovered that social service providers in Klamath County believed Native American children experiencing maltreatment might be slipping through the cracks. In an effort to find out how to better serve these children and their families, the current study involved interviews with 11...
The Diels-Alder reaction represents a promising tool for use in
asymmetric synthesis. The reaction involves a rigid transition state
that facilitates the formation of one diastereomeric transition state
and is reversible. This satisfies two necessary criteria for
asymmetric synthesis.
The Diels-Alder reactions of 1,l-dialkylspiro[2.4]-4,6- heptadienes
with maleic anhydride and p-benzoquinone...
Policy analysts designing programs to improve the
efficiency and expand the use of water in the irrigation of
farm lands often enlist benefit-cost analysis as a means of
assessing impacts and feasibility. While on-site comparisons
of costs and benefits are important factors in project
assessment, other dimensions such as risk,...
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 morphology and ecological importance of habitats associated with the margin of third-order stream channels in the Oregon Cascades were studied in streams in three different riparian types: 450-year-old conifers, 40-year-old alder, and an open, herbaceous-dominated clearcut. Margins, backwaters, and side channels in streams create important habitat for fry of...
