By regarding the classical non abelian cohomology of groups from a 2-dimensional categorical viewpoint, we are led to a non abelian cohomology of groupoids which continues to satisfy classification, interpretation and representation theorems generalizing the classical ones. This categorical approach is based on the fact that if groups are regarded as categories, then, on the one hand, crossed m...

The use of Lax pair tensors as a unifying framework for Killing tensors of arbitrary rank is discussed. Some properties of the tensorial Lax pair formulation are stated. A mechanical system with a wellknown Lax representation – the three-particle open Toda lattice – is geometrized by a suitable canonical transformation. In this way the Toda lattice is realized as the geodesic system of a certai...

The ability of lymphokine-activatedkiller (LAK) cells to mediate antibody-dependent cellular cytotoxicity and its efficacy against a LAX resistant tumor were investigated. Cells ofthe MH134 murine hepatoma line are scarcely lysed by LAX cells generated in vitro by incubatiOn of G3H/HeN mousespleen cells with humanrecombinantinterleukin2 (rIL 2). However, the splenic LAX cells potently lysed the...

This paper develops a criticism of Kant’s transcendentalism, claiming that his idea reason fails to take into account the Darwinian continuum linking higher mammals and human primates. At same time, ontology epistemology fail consider fact humans are product contingent yet irreversible linguistic, cultural, Intentional (written with capital “I”) configuration their form life. The author favors ...
