Metropolitan areas today must dispose large volumes of
sewage sludge produced during the wastewater treatment process.
This research was conducted to study the effect of large applications
of municipal sewage sludge on (a) the distribution of N and trace
elements (Cd, Cr, Cu, Mn, Ni, Zn) in the soil profile,...
Ten experiments were conducted to determine the vitamin requirements
of coturnix quail (Coturnix coturnix japonica) to 2 weeks
of age using a glucose monohydrate-isolated soybean protein diet.
A preliminary study consisting of 2 separate experiments was
conducted to determine those vitamins essential to the growing
coturnix. This study revealed that...
The degradation of kraft pulping wastes in estuarine waters
was measured in terms of the following parameters: five-day 20°C
B.O.D., the Pearl-Benson Index, and toxicity to the bay mussel
(Mytilus edulis L.). The waste tested was the total effluent from a
combined pulp and paper mill producing 430 tons of...
Traditionally employment and output have been the major two criteria for evaluating aggregate performance in a dual economic model for less developed countries. This has been mainly discussed by transferring labor from the agricultural sector to non-agricultural use. Most models are specified in such a manner that the migrated agricultural...
Crater Lake, originally barren of fish, was stocked on an
irregular basis from 1888 through 1941 with several species of
salmonids. Two species occur in the lake today--kokanee salmon
(Oncorhynchus nerka) and rainbow trout (Salmo gairdneri). This
study was initiated in the summer of 1986 to evaluate the ecology of...
Replication associated protein and enzyme activity levels increase as cells enter
S-phase of the cell cycle and diminish as cells leave S-phase. Accordingly, replication
associated functions decrease as myoblasts withdraw from the cell cycle to terminally
differentiate. In an effort to understand signals effecting growth associated expression
of genes, the...
The species compositions and densities of the littoral and pelagic zooplankton
assemblages in Crater Lake were compared. The littoral and pelagic zooplankton
assemblages of most lakes are typically different due to different habitat conditions in the
two zones. The littoral zone of Crater Lake lacks many of the habitat characteristics,...
Distribution and life history characteristics of lacustrine-adfluvial bull trout (Salvelinus
confluentus) were described in the North Fork Skokomish River Basin (including Lake
Cushman, a reservoir) from 1994 to 1996. Day snorkeling was conducted in the river to
determine initiation of the bull trout spawning migration, abundance of spawners, and
duration...
Significant use of cold in-place recycling (CIR) has occurred in
Oregon since 1984 as an alternative to other rehabilitation techniques
or to the reconstruction of distressed asphalt concrete (AC) pavements.
Due to the initial success of the projects cold recycled during 1984-85,
the Oregon Department of Transportation (ODOT) and Oregon...
