The Q-band heteromorphisms of chromosome 21 were used in a sample of 48 families with a Down's syndrome child to evaluate the origin of non-disjunction. The parental origin and the meiotic error were determined in 27 families, and in eight families only partial information was obtained. Paternal and

The -calculus provides a system of realizers for classical free (cf. natural) deduction in the absence of disjunction. We identify two forms of disjunction, one derived from Gentzen's sequent calculus LJ and one from LK, and develop the corresponding metatheory for extended with disjunction. We desc
In this comprehensive investigation, we studied three different neurorrhaphy models in an attempt to elucidate the potential of termino-lateral nerve repair to original and adjacent nerves. In experimental group 1, the peroneal nerve was sectioned and then attached to the posterior tibial nerve in a
