Structural geologists are well aware of the fact that isotropic rocks are quite exceptional in nature. Whicheverorigin, sedimentary, metamorphicormagmatic, rocks are shaped with a plane of mineral flattening, the foliation in geologists' jargon, and with a line ofmineral elongation, the lineation. Just like a good quarryman, a trained structural geologistwill detectapreferredorientationin an apparently isotropic granite. Preferred mineral orientation and thus structural anisotropy are the rule in nature. Consideringthe largevariationsinelasticcoefficientsofrock-forming minerals, itcould be...

1 Industrial Mathematics in Linz The Johannes-Kepler-University is situated in Linz, which is the industrial center of Austria. This location provides unique opportunities for cooperation between in dustry and a university which derives its name from one of the most eminent ap plied mathematicians of all times. The mathematics department was founded in the late Sixties, the first students graduated in 1974. In these boom times, they had no problems of finding jobs in industry. However, their employers were then more interested in their general training than in their specific mathematical...

Where do you begin to look for a recent, authoritative article on the diagnosis or management of a particular malignancy? The few general oncology textbooks are generally out of date. Single papers in specialized journals are informative but seldom comprehensive; these are more often preliminary reports on a very limited number of patients. Certain general journals frequently publish good in-depth reviews of cancer topics, and published symposium lectures are often the best overviews available. Unfor tunately, these reviews and supplements appear sporadically, and the reader can never be sure...

This volume contains thirteen papers and one extended abstract based on talks given at the symposium "Inverse Problems and Optimal Design in Industry" which took place from July 8 to 10, 1993, in Philadelphia. This symposium was jointly organized by ECMI an SIAM, with the cooperation of IMA (Minnesota), INRIA, and SIMA . The organizing committee was co-chaired by the editors of this volume and included, in addition, V. Boffi (SIMAI, Italy) G. Chavent (INRIA, France), D. Colton (University of Delaware, USA) and A. Friedman (IMA, USA). Financial support from the U. S. Department of Energy is...
