En este libro ampliamente elogiado, que se presenta en una edición revisada y aumentada, Luttwak desvela la particular lógica de la estrategia nivel a nivel, desde la táctica de combate a la gran estrategia.

There is an increasing challenge for chemical industry and research institutions to find cost-efficient and environmentally sound methods of converting natural resources into fuels chemicals and energy. Catalysts are essential to these processes and the Catalysis Specialist Periodical Report series serves to highlight major developments in this area. This series provides systematic and detailed reviews of topics of interest to scientists and engineers in the catalysis field. The coverage includes all major areas of heterogeneous and homogeneous catalysis and also specific applications of...

Proceedings of a symposium organized by the IAEA and FAO, Vienna, 19-23 August 1985. The symposium examined the usefulness for plant breeding purposes of somaclonal variation, i.e. the occurrence of mutations during in vitro culture with or without the application of ionizing radiation or other mutagens. Another issue was finding ways and means of maintaining the genetic integrity of plants under in vitro conditions, such integrity being of vital importance if in vitro techniques are to be used to propagate virus-free clones of economically important plants, or to preserve germplasm in gene...
