A major objective of this investigation was to determine the
possible roles, if any, of poly-β-hydroxybutyrate and products of
its metabolic breakdown in symbiotic nitrogen fixation by nodule
bacteroids. Changes in poly -β- hydroxybutyrate content and in
activities of nitrogenase, β-hydroxybutyrate dehydrogenase, and
isocitrate lyase were studied under various conditions...
Air temperatures and soil temperatures at the surface, two inches,
and four inches under a grass cover were recorded over a 93 day period.

Elutriation of silica sand particles from a 0.9 X 0.9 m cold
fluidized bed was studied. Data were collected for cases with and
without tubes. During experiments the position of the tube bundle
above the distributor plate and the superficial velocity were varied.
Runs were made at velocities of 0.9...
