The very restrictive quotas of cod in the Baltic Sea are a strong force for searching alternatives. Since 1996 for instance, the cod quota for the German fishery was reduced from 22 000 t to 13 000 t in the year 2001. And further cuts took place in 2002. However,...
Salmonid B lymphocytes were stimulated both in vivo and in vitro
and shown to produce antibody specific for the immunogen. A passive
hemolytic plaque assay was employed to demonstrate B cells producing
specific antibody. Characterization of plaque forming cells (PFCs)
involved sequential inhibition with a series of graded concentrations
of...
The in vitro effects of cortisol in regulating salmonid B cell functions were
investigated. B cells at three distinct stages of differentiation were examined for
cortisol sensitivity. B lymphocyte responses were examined 1) during the early stage
of the precursor, 2) during the intermediate stage of differentiation associated with
clonal...
Hybrids with abnormal development were obtained when particular
genotypes of Phaseolus vulgaris L. were crossed. The phenotypic
aberrations of the F₁s included retarded growth, chlorosis of the
trifoliate leaves and the formation of adventitious roots on the
hypocotyls. The expression of the abnormalities was dependent on the
temperature. At high...
These essays are an attempt to rebuild memories that explore the nature of
work and family. They explore how work knocks against the joints of the body and
against the joints between family members, and, as time passes, how the next
generation inherits the family line of work only to...
