The feasibility of fluidized bed combustion of coal for commercial
and industrial steam power generation has been established
and reported in the literature. Satisfactory removal of sulfur
oxides from the combustion product gases has also been reported.
In this experiment various heat exchanger tube patterns,
of commercial size tubes, were...
A program of research has been established at Oregon State
University to study wood residue combustion using an experimental
spreader-stoker combustor. This research was conducted to increase
the understanding of combustion occurring in wood fired boilers.
Using Douglas Fir screened to 3/8-3/4 inches, two 4x4 factorial
experiments were conducted varying...
A mathematical model of the atmosphere in an airshed is developed, which relates pollutant source distributions and intensities
to the volume of air available for dispersion and to pollutant concentrations
or air quality standards. It can be used as a tool for obtaining
an answer to an air resource management...
The seasonal variation of wind speed fluctuations is studied at
four locations in The Dalles area of the Columbia River Gorge.
Three of the sites are located in or near the valley floor while the
fourth site is on top of a 900 m (3000 ft) ridge just north of...
Flat, laminar, premixed hydrocarbon-air flames were stabilized
on a porous-plate burner. In addition to temperature profiles,
concentration profiles were measured for methane, ethane, ethylene,
propane, acetylene, propylene, carbon monoxide, carbon dioxide and
oxides of nitrogen. Dead space thickness, luminous flame zone
thickness and hydrocarbon disappearance point responses were also
monitored....
The concentrations of calcite, opal and quartz have been measured in 113 South Atlantic core tops. The remainder of the total sample has been calculated as clay. A method for the quantitative determination of opal has been developed.
Calcite is the dominant factor in South Atlantic sediments; its pattern can...
Wild turkeys (Meleagris gallopavo) were first successfully introduced into Oregon and Washington in the 1960s; the population has grown in size and expanded in distribution to a point where it provides an important recreational hunting opportunity in both states that generates significant funds for habitat conservation and contributes financially to...
This paper describes a methodology developed for evaluating
the acceptance of a regional drug information service in providing
patient-specific information. This methodology employs a blinded
study design and uses activity in the patient chart for determining
the acceptance of information.
A total of 60 requests were referred to the regional...
