The use of municipal refuse (RDF) as fuels has
received widespread attention for reason of its energy
equivalence and the increasing lack of available landfill
sites. The principal obstacle to the construction of combustion
facilities is that RDF produces toxic compounds,
including heavy metals and such organic compounds as PCDD...
Attention has been drawn to the observation that environmental benefits under the current regulatory approaches are diminishing with respect to increased pollution control costs. Regulators have begun to appreciate that while environmental gains can still be achieved under the current command and control system, the most significant environmental gains have...
A theoretical argument is presented to suggest that engineering curriculum be
designed to develop social capital. Additionally, the value of social capital in the
retention of students in the College of Engineering, and the development, role, and value
of social capital in an electrical engineering laboratory is evaluated. Data collected...
This manuscript-style dissertation explores Diné (Navajo) education and teaching in the context of a research project that negotiated the demands of both Navajo Nation IRB and Oregon State University IRB.

Since the introduction of pure oxygen activated sludge systems in
the late 1960's, proponents have claimed several advantages resulting
from the elevated dissolved oxygen (DO) levels maintained. However,
numerous comparative studies have failed to produce a consensus of
professional opinion regarding the validity of these claimed advantages.
The purpose of...
Hydrazine based fuels are used by the Air Force for the Titan II
and Minuteman III missiles and the F-16 aircraft and by the National
Aeronautics and Space Administration for propulsion systems and the
Space Shuttle Program. These uses represent significant production,
transportation and storage of these fuels, and, as...
More than 65,000 organic chemicals are currently in commercial production with
approximately 1000 added each year. Many chemicals are released into the environment as organic mixtures derived from complex hazardous or solid wastes. Of these, more than 1000 chemicals are of environmental concern because of their production quantities, toxicity, persistence,...
