The result of more than three decades of dedicated scholarly research by the Forschungsstelle Gregor von Nyssa (Munster), the Lexicon Gregorianum constitutes the most comprehensive Greek-German dictionary ever of the language used by Gregory of Nyssa. It is, and will be for the foreseeable future, the only dictionary available specifically addressing the vocabulary of late Classical Greek. Far from being a simple word list this seminal reference work documents Gregory's complete vocabulary, taking account of the syntax, meaning and connotations of every occurrence...

The use of tritium as a basic fuel material in a thermonuclear fusion reactor raises particular safety issues due to the combined effects of its physico chemical properties and radioactive nature. Furthermore the possibility of attaining further significant progresses in developing and demonstrating the feasibility of tritium burning devices relies on the handling of tritium macroquantities, say ten grammes, in a safe and reliable manner. It is also undoubted that, apart from technological constraints, any validation and exploitation of thermonuclear fusion as a source of energy will be...
