Because of the fuel crisis and problems associated with thermal
pollution there is new impetus and urgency for developing more
efficient energy conversion systems for power generation. A preliminary
analysis was undertaken to determine the potential of staged
Rankine cycle systems for substantially higher efficiency. It was
necessary to optimize...
This comparison study involved the exploration of architecture and social life of the thirteenth century Medieval, sixteenth century Tudor and eighteenth century Georgian periods. Within the architectural and social categories, the specific objective was to examine the changes in the five hundred year period. Three specific houses were chosen as...
Vibrio marinus, strain MP-1, was shown to grow from pH 6.7
to 8.5, with an optimum at 7.3. Growth was inhibited below salinity
10%₀ and above 60%₀ . The upper temperature limit of
growth was 20 C, and growth was very rapid with aeration at 15 C.
Heating of the...
Raw and biologically stabilized Kraft mill effluents were introduced
into laboratory artificial streams at a ratio of 15 ml per liter
of water over a two year period. Effluent from the stabilization pond
of a second mill was introduced at concentrations of from 5 to 40 ml
per liter of...
The relative rates of hydrogen abstraction from a series of 13
arylmethanes by the trichloromethyl radical were determined at 70°.
The attacking radical was generated from bromotrichloromethane us
ing benzoyl peroxide as the initiator. The solvent was benzenebromotrichloromethane.
An excellent correlation, with a coefficient
of 0.977, was obtained when the...
A biosystematic investigation was undertaken in 15
species and three subspecies of the genus Aster, in western
North America. Previous studies had been based entirely on
external morphological features, and it was believed that
much could be learned about the natural affinities of the
taxa by exploring their cytological and...
Fluorescence polarization measurements on beef liver glutamate
dehydrogenase conjugated with pyrene butyric acid demonstrate that
the association of the enzyme is adequately described by a reversible
indefinite association with a single equilibrium constant. The data
obtained with protein concentrations up to 0.7 mg/ml in 0.05 M
potassium phosphate, pH 7....
Three species of bacteriophagous nematodes, Pristionchus
lheritieri (Maupas) Paramanov, Pelodera chitwoodi (Bassen)
Dougherty and Rhabditis sp. were studied to determine their potential
roles as vectors of selected insect pathogens, Bacillus thuringiensis
Berliner, Beauveria bassiana (Balsamo) Vuillemin, Metarrhizium
anisopliae (Metchnikoff) Sorokin and a nuclear polyhedrosis
virus of Trichoplusia ni Hubner.
Chlorine...
