Digestibility experiments were carried out with dairy heifers to
determine the digestibility of orchard grass, Dactylis glomerata, and
also to evaluate the accuracy of various indicator techniques in pasture
digestibility experiments. Chromic oxide was used as an external
indicator to predict fecal dry matter output in three digestion
trials. Cut...
A graphical method, based on a set of acid-base titrations, is
presented for the determination of the carbon dioxide speciation in
natural solutions. The application of this method, in conjunction
with measurements of the partial pressure of carbon dioxide with
which our solutions were in equilibrium permitted the calculation
of...
Cells of an obligately psychrophilic marine bacterium, Vibrio
marinus, strain MP-1, were grown at 4 C and 15 C and studied for
possible physiological differences. No differences were noted in
sugar fermentation or temperature-shift growth studies; in both cases
adequate nutrients were available. Some differences were noted in
viability retention...
