Purpose This study was conducted to investigate the influence
that awards of financial aid have on the educational decisions and
academic achievement of applicants for freshman year financial aid
at Oregon State University. The study was primarily concerned with
the effectiveness of financial aid in assisting students to enroll and...
This history concerns the scientific contributions of Charles
Babbage (1791-1871) to mathematics, to the invention of calculating
machines, and machine tools, to the development of scientific ideas
through a wide variety of scientific investigations and his involvement
in several different scientific reforms. Babbage considered himself
a philosopher in the broadest...

The concept of large-scale natural resources planning and
management is not new. The idea that resources and their human users occur as systems over large geographic areas has a long established tradition in forest, range, water, and air management sciences. Recent trends in this thinking concern the recognition of the...
The presence of per- and polyfluoroalkyl substances (PFAS), organic contaminants first synthesized in the 1940s, has been reported worldwide in a variety of environmental matrices and ultimately in biological systems including humans. Ongoing research into PFAS has included identifying novel PFAS, assessing their fate and transport in the environment, and...
Per- and polyfluoroalkyl substances (PFAS) are anthropogenic surfactants that have recently been identified as persistent organic pollutants. These so called “Forever Chemicals” have been detected in drinking waters, ground waters, soils, and consumer and industrial products globally; with environmental impacts stretching into the artic, far from known PFAS sources. The...
Electrical resistivity and thermoelectric power measurements
have been made over the temperature range of 450° to 600°C on
n-type liquid thalliurn-tellurium solutions. Liquids with compositions
from 61.5 to 72.0 atomic percent thallium were studied. In addition,
alloys of some of the three component thallium-teIlurium solutions
containing small amounts of silver,...
