Abstract: A system for countering the rolling motion of a marine vessel, includes one or more sensors adapted to characterize a sea condition approaching the vessel, one or more control systems, a computer, and one or more active stabilizers. The computer is adapted to receive the characterized sea condition data, is further adapted to generate one or more control signals in dependence on the characterized sea condition data, and is still further adapted to transmit the or each control signal to the or each control system. The or each control system is in turn adapted to actuate the or each active stabilizer in response to receipt of the or each control signal, to counter the rolling motion of the marine vessel.

Abstract: A process for purifying pentostatin from a crude fermentation beer comprising the steps of 1) applying the fermentation beer to a strong cation exchange resin; 2) eluting with ammonium hydroxide; 3) concentrating the eluate; 4) applying the concentrated eluate to a strongly basic anion exchange resin charged with borate ion; 5) eluting with water; 6) applying this eluate to styrene-divinylbenzene beads prewashed with ethanol; 7) eluting the beads with water; and 8) recrysllyzing the pentostatin from water and methanol to yield a product that is greater than 99.7% pure.
