An algebraic determination of closed orientable 3-manifolds
(American Mathematical Society (AMS), 1979)
Associated with each polyhedral simple closed curve j in a closed, orientable 3-manifold M is the fundamental group of the complement of j in M, π₁(M — j). The set, K(M), of knot groups of M is the set of groups π₁(M — j) ...
PaeExo IX: A unique deoxyribonuclease from Pseudomonas aeruginosa active in the presence of EDTA
(Oxford University Press, 1979)
A new deoxyribonuclease, PaeExo IX, has been purified to electrophoretic homogeneity from extracts of Pseudomonas aeruginosa strain PAO. This enzyme, which is active in the presence of EDTA, is equally efficient in hydrolyzing ...
