We present a classical density functional to model the soft, repulsive potential of a Weeks-Chandler-Andersen (WCA) fluid using Soft Fundamental Measure Theory (SFMT) with temperature-dependent parameters inspired by the Barker-Henderson method. Our functional uses soft spheres to model the soft-sphere WCA potential, and gives results that are in good agreement...
The radiorespirometric method was used to study the catabolism
of glucose in intermolt crayfish. Rapid and extensive conversion
of C-3(4) of glucose to C¹⁴O₂ indicated that a significant
portion of the administered glucose was routed into the glycolysis-
Krebs cycle sequence. High yields of C-6 of glucose in the respiratory...
Bluegill sunfish, Lepomia macrochirus, and cutthroat trout,
Salmo clarki, were exposed to a rapidly declining oxygen tension
for a period of time sufficient to just cause loss of equilibrium in
the fish. During recovery from the stress, measurements of
oxygen uptake, blood lactic acid, blood glucose, liver glycogen,
muscle glycogen,...
Great importance has been attributed to the visual aspects of
sexual communication in semi-terrestrial crabs and although P.
crassipes may utilize visual signals, pheromones and chemotactile
signals are important in the release of mating behavior. In the subtidal
C. magister pheromones seem to mediate both courtship and
mating behavior. Visual...
The metabolism of Strongylocentrotus purpuratus (Stimpson)
was investigated at several levels of urchin organization. Some experiments
were performed with tissues from recently collected
(acclimatized) urchins, Other experiments were performed with tissues
from urchins held at one of two temperatures (acclimated) for
30 days.
Body-component oxygen consumption was measured for bodywall,...
This study was designed to test the relative effectiveness of
teaching Writing 111 at Oregon State University by closed-circuit
television as compared with conventional classroom procedures; the
hypothesis was that the students taught by television (the experimental
group) would achieve as well as the students taught in conventional
classrooms (the...
Osmotic and ionic regulation was studied in the North
American crayfish Pacifastacus leniusculus (Dana), stepwise acclimated
to increasing salinities. Stepwise acclimation involved transferring
crayfish at 48 hour intervals from freshwater to 100% seawater
in 20% increments. In experiments where 70% seawater was
used, animals were moved directly from 40 to...
The heart rate, oxygen consumption, survivorship, and 1-lactate
accumulation were determined in the intertidal limpets Collisella pelta
and Collisella digitalis in relation to laboratory desiccation at 15°C
or 30°C. Water loss was computed as a percentage of total initial body
water (wet weight - dry weight). Although water was lost...
Osmotic and ionic regulation was studied in the Dungeness
crab, Cancer magister, after acute exposure to a range of five
salinities from 25% to 125% sea water (100% = 32%). Blood, urine
and muscle tissue were sampled at 24 and 48 hours after exposure.
Analyses were made of blood and...
