A computer simulation was developed as a technique for
studying the effects of the process dynamics on the operator's
sampling and control behavior. This methodology was
used to study the effects of the process input memory
variation in the presence of different observation noise
levels. It was concluded that the...
A cell free extract from Saccharomyces cerevisiae containing the
enzyme that causes reduction of the 24(28)methylene group on the side
chain of ergosterol has been studied. Optimal conditions for the
24(28)methylene reductase were obtained. The enzyme activity was
increased in cells grown with ethanol as the substrate. The Km was...
Monomer-tetramer association equilibrium and the oxygen
binding of the hemocyanin from Callianassa californiensis
were measured at a number of pH values and magnesium
ion concentrations. Magnesium binding of the hemocyanin
was also measured at several pH values. A thermodynamic
model, which satisfied the constraints from the experimental
results, was developed...
Mathematicians have been concerned with population growth
and movement since the days of Leonhard Euler and Thomas Malthus.
Chapter i of this paper sketches the history of the development of the
modern population theory.
In Chapter II, a partial differential equation is derived which
governs the growth and movement of...
In introducing the method of electrical images we first consider
the elementary problem of finding the electric field of a single point
charge and an infinite conducting plane. Then a problem involving a
conducting sphere and an exterior point charge is investigated and
the results are applied in the solution...
The pathogenesis, diagnosis and treatment of bacterial
dermatitis and various canine allergic dermatitidies including
allergic inhalant dermatitis, contact dermatitis and
flea allergy dermatitis were studied. The effect of specific
nonprotein and protein components of commercial flea
antigens on the gross and microscopic appearance of intradermal
injections was investigated. Additionally, a...
