Slozhnost problemy lecheniya tyazhelykh sochetannykh povrezhdeniy ne mozhet byt reshena imperativnostyu khirurga i ego virtuoznoy tekhnikoy. Letalnost pri politravme sostavlyaet 35- 80%. Ostrota i dramatizm pri sochetannykh raneniyakh grudi i zhivota usugublyayutsya fenomenom vzaimnogo otyagoshcheniya. Mnogochislennye i protivorechivye vystupleniya, posvyashchennye probleme sochetannoy travmy, svidetelstvuyut o tom, chto reshat ee traditsionnoy metodologiey prakticheski nevozmozhno. Avtorami dokazano, chto infuzionnaya terapiya v sostave komponentnogo lecheniya ostroy...

Since the introduction of the functional classes HW (lI) and WT HW (lI) and their peri- odic analogs Hw (1I') and (1I'), defined by a concave majorant w of functions and their rth derivatives, many researchers have contributed to the area of ex- tremal problems and approximation of these classes by algebraic or trigonometric polynomials, splines and other finite dimensional subspaces. In many extremal problems in the Sobolev class W (lI) and its periodic ana- log W (1I') an exceptional role belongs to the polynomial perfect splines of degree r, i.e. the functions whose rth derivative takes on...

Papers from the Sixth All-Union Conference on Growth of Crystals comprise Volume 16 of this series. The articles were chosen with a view to more fully elucidate the basic problems of crystal growth as reflected in domestic and foreign reviews and in original studies. This volume consists of six parts. Part I is devoted to mechanisms of crystal growth that are important for production of materials with given properties. This part examines the temporal evolution of an inhomogeneous state and the array of semicellular and eutectic structures during microstructure formation, the effect of...

Early in this century, the newly discovered x-ray diffraction by crystals made a complete change in crystallography and in the whole science of the atomic structure of matter, thus giving a new impetus to the development of solid-state physics. Crystallographic methods, pri marily x-ray diffraction analysis, penetrated into materials sciences, mol ecular physics, and chemistry, and also into many other branches of science. Later, electron and neutron diffraction structure analyses be came important since they not only complement x-ray data, but also supply new information on the atomic and...
