Bacillus megaterium is a gram - positive rod-shaped endospore-forming bacteria. They are used as an effective soil modifier, having the ability to disperse phosphorus. In turn, phosphorus plays an important role in several physiological and biochemic

Bijective linear transformations of the matrix algebra over an arbitrary field that preserve simultaneous diagonalizability are character- ized. This result is used for the characterization of bijective linear trans- formations monotone with respect

Criteria analogous to Robson’s and Fuchs’ are given for a semiring to be isomorphic to a full matrix semiring. The necessity of additional conditions (compared with the case of rings) is investigated.

The hydrodynamic aspects of the propagation of a liquid non-aqueous contaminant in aquifers and the development of a zone of primary contamination are considered. Special attention is paid to the interaction of the contaminant front with the interfac
