The objective of this study was to determine whether wild populations of trout in the North Fork of the Middle Fork of the Willamette River can support a catch rate of 0.3-0.5 trout per hour at current levels of effort and to predict how different size and bag limits would...
There were two viable theories of generation, preformation
and epigenesis, existing in the Seventeenth and
Eighteenth Centuries. Due to their irreconcilable nature,
they were often at loggerheads during this time interval.
The status of these generation theories can be effectively
understood in terms of Thomas Kuhn's conception of preparadigm
science....
The objective of this paper is to conduct a geographical inventory
of a sand and gravel site, Lower Kiger Island, so as to identify and
evaluate other potential land uses subsequent to the extraction of its aggregate
resources. This information is intended to aid citizens, land use
planners, and sand...
Interactions between sediment bacteria and available phosphate
necessary for algal production in a eutrophic lake were studied.
Twenty percent of the organisms isolated solubilized phosphate forms
such as CaHPO₄, Ca₃(PO₄)₂, FePO₄, Mg₃(PO₄)₂ and Al₂(PO₄)₂.
Solubilization of phosphates occurred under conditions of aerobic
growth.
Upon quantitative analysis, some isolates were capable...
The dynamic philosophy of education as applied to the undergraduate Civil Engineering program has been influenced by such factors
as the introduction of new theories, the demands
and needs of our society and the personnel responsible for teaching.
These changes
are reflected in the curriculum as witnessed
by a historical...
Tungsten alloys containing approximately 0.75 and 2.3 vol pct Zr0₂
were prepared by powder metallurgical methods from blends
of commercial
tungsten powder and ZrW₂ powder.
A heat treatment of the extruded rods
at 1800°C was found to produce a stable structure with a
dispersion of
Zr0₂ particles in the tungsten...
