Sommario/riassunto

This volume contains the proceedings of the conference "Casimir Force, Casimir Operators and the Riemann Hypothesis - Mathematics for Innovation in Industry and Science" held in November 2009 in Fukuoka (Japan). The motive for the conference was the celebration of the 100th birthday of Casimir and the 150th birthday of the Riemann hypothesis. The conference focused on the following topics: Casimir operators in harmonic analysis and representation theory Number theory, in particular zeta functions and cryptography Casimir force in physics and its relation with nano-science Mathematical biology Importance of mathematics for innovation in industry The latter topic was inspired both by the call for innovation in industry worldwide and by the fact that Casimir, who was the director of Philips research for a long time in his career, had an outspoken opinion on the importance of fundamental science for industry. These proceedings are of interest both to research mathematicians and to those interested in the role science, and in particular mathematics, can play in innovation in industry.

Sommario/riassunto

A professional reference that shows how mass integration techniques are used to maximise efficiency and sustainability and minimize the pollution of process systems and plants. Plant and unit operations professionals will save time and money by using the detailed tools and applications as part of their understanding of systematic process development. More generally it will be an important resource for those working with what commonly referred to as P2 (Pollution Prevention) technology.In addition to practitioners developing new systems and, more commonly, retrofitting old systems, the
