Essentially affine categories,ct sense in a non pointed context. The idea has been to investigate the properties of the fibration of points which, in the pointed case, characterize the validity of the short five lemma, and to take these as a definition of protomodularity.

A number of physical parameters regulate the content and fate of reactive components of SOC pools. Physical mechanisms include encapsulation of SOC through organo-mineral complexes where finer particles with hi

The deposition apparatus was constructed from Pyrex glass and Teflon fittings in order to prevent contamination from stopcock greases. Conditions were developed for obtaining the boron in the shape of rods up to 2 mm in diameter and

Identifying and using patterns in sequential data,arning from data whose input sequence follows a regular sequence. To do so requires that we regard the input data as a stream and identify regularities in the data values as they occur. In this brief survey I review three sequential-learning problems, examine some new, and not-so-new, algorithms for
