(Cambridge University Press (CUP), 1999-05-01)
a hydrolase activity that cleaves lysyl-p-nitroanilide (Lys-pNA) has been purified from the cytoplasm of Lactococcus lactis subsp. cremoris AM2 by chromatography on DE52, DEAE Affi-Gel Blue Gel, Hydroxyapatite Bio-Gel HTP ...

Gauge dependence in chern–simons theory
(World Scientific Pub Co Pte Lt, 1999-01-30)
We compute the contribution to the modulus of the one-loop effective action in pure non-Abelian Chern-Simons theory in an arbitrary covariant gauge. We find that the results are dependent on both the gauge parameter (alpha) ...

(Cambridge University Press (CUP), 1994-10-01)
Terminal complement component deficiency predisposes to meningococcal infection and is inherited in an autosomal co-dominant manner. An Irish family is described, in which 2 of 3 brothers had recurrent meningococcal ...
