The author presents his own concept of potential landscape phytocomplexes as the structural space units on the level of plant organization higher than an ecosystem (i.e. above biogeocenosis). He also defines the concept of vegetation landscape in a typological sense. Basing on the example of Sudety Mountains and Foreland regions, the author demonstrates a method of distinguishing landscape phytocomplexes and their utilization for regional description of vegetation and geobotanical regionalization.

Traditionally ceramics have been shaped from powders and densified at temperatures close to their liquid point. New processing methods using various types of sols, gels, and organometallic precursors at low temperature which enable densificatlon at elevated temperatures well below their liquidus, hold the promise of producing ceramics and glasses of controlled and reproducible properties that are highly reliable for electronic, structural, space or medical applications. Ultrastructure processing of silicon alkoxides in acid medium and mixtures of Ludox HS-40 (120Å spheres from DuPont) and Kasil (38% K2O &62% SiO2) in basic medium have been aimed at producing materials with a range of well defined pore sizes (∼20-400Å) to study physical phenomena and materials behavior in well characterized confined geometries. We have studied Pt/C surface replicas of some of these porous sol-gels prepared at temperatures below their glass transition point.
