Abrupt phase transitions in the structure of ferromagnet/ electroactive polymer/ non-magnetic metal have been found in the number of studies in magnetic field as huge magnetoresistive effects. The sign of magnetoresistance depends on the conductivity state that the polymer has possessed at the beginning of the experiment.The ways of managing of metal/ dielectric phase transition in the polymer layer with the aid of weak external magnetic field are considered. The model of local conversion of charge mobility in the conductive channels is suggested.

This monograph studies for the first time the biological principles of the comprehensive utilization of pine forests. In the context of the immense usefulness of the raw material they provide: timber, nuts, and resin. The morpho-physiological, ontogenetic, ecological-geographic, intra- and interpopulation relations between growth, generative, and resin-forming processes in Siberian stone pine have been demonstrated under standard conditions and under conditions of experimental modification of root-leaf proportions. Using a complex evaluation of appropriate indexes of productivity, practical recommendations have been offered for a differentiated combination of elements and types of complex. Suggestions have been examined for the selective breeding of trees and plantations on the basis of economic indexes; growth, yield, and resin output; as well as aspects of yield control. This book is designed for the use of scientific workers in the field of forest science and specialists in forestry.

Existing calcium gallate CaGa 2 O 4 based luminescent materials radiating in visible IR region have been reviewed. IR luminophores have been studied but slightly but their practical implementation is of interest. CaGa 2 O 4 specimens activated with Yb 3+ rare-earth ions have been synthesized using the solid-state method. The structure and luminescent properties of CaGa 2 O 4 : Yb 3+ have been studied. CaGa 2 O 4 : Yb 3+ excitation with 940 and 980 nm radiation generates luminescence in the 980–1100 nm region. Data on the electron level structure in Yb 3+ ions suggest that the excitation and luminescence occur directly in the Yb 3+ ions with only a passive role of the base lattice. The luminescence spectra contain three peaks at 993, 1025 and 1080 nm. These luminescence peaks are caused by electron optical transitions from excited to main state in Yb 3+ ions. 993 nm band luminescence intensity has been studied as a function of Yb 3+ activator ions concentration. Introduction of Na + ions into the luminophore increases IR luminescence intensity. Optimum (Ca 1- x - y Yb x Na y )Ga 2 O 4 luminophore composition has been suggested at which the 993 nm luminescence intensity is the highest.

The present study investigates photoinduced changes of magnetostriction in yttrium-iron garnet (YIG) single crystals. Single crystals of Y3Fe5O12 were grown from BaO-B2O3 (YIG(Ba)), PbO-PbF2 (YIG(Pb)) and PbO-PbF2:SiO2 (YIG(Si)) solutions from flux. Photoinduced magnetostrictive response types for these three kinds of YIG crystals are quite different. The magnetostrictive constants, the trigonal symmetric internal stresses and their photoinduced changes were calculated for all samples. The conclusion is that the internal stresses in the crystal lattice, caused by defects, determine the photoinduced response type of the crystal.

The Reference Book of Ternary Oxide Systems phase diagrams computer models is presented. Its computer models of T-x-y diagrams give a possibility to calculate the mass balances at any temperature, to observe crystallization history and the process of microstructure forming at different crystallization stages. The investigation of concentration fields with the different phase constituents on the T-x-y diagram projection by means of its computer model is considered. Phase diagram of CaO-SiO2-Al2O3 system is used as an example.

The endothelium plays a crucial role in regulating vascular tone, proliferation and migration of smooth muscle cells, and it maintains a balance of profibrinolytic and prothrombotic activity. These effects are mediated by the releasing of vasoactive substances. The main endothelium-derived vasodilators include nitric oxide, prostacyclin and bradykinin. These substances also regulates the local processes of a hemostasis and suppresses the smooth muscle cell growth. The vasoconstrictors, such as endothelin, thromboxane A2 and a ngiotensin I I contribute to the a therogenesis. The imbalance of endothelium-derived relaxing and contracting factors is defined as endothelium dysfunction. A number of conditions recognized as risk factors of atherosclerosis result to endothelial dysfunction by that or otherwise. So is actual to asses the indexes of endothelial function in men with risk factors of a therosclerosis before appearance of clinical signs of disease and assigning of pathogenetic therapy at this stage that will allow to improve the prognosis of patients.

The reduction of the rotational chloroplast motion velocity (CMV) during the exposure of Elodea cells to hypertonic solutions of PEG-4000 is satisfactorily described by an exponent. The dynamics of reduction correlates with the dynamic equilibration time (T(eq)) between osmotic potentials of cell cytoplasm and external solution. The acceleration of the chloroplast motion, for example by gadolinium ions, results in the reduction of T(eq), and this is supposed to be due to the increase of the contribution of the near-membrane Nernst layers to transmembrane transfer resistance resulting from the blowing-off of a part of the layer by moving cytoplasm.

The effect of cold deformation on the variation of hardness during aging of sheets from alloy VT35 with β-structure is studied. Diagrams of isothermal transformations due to aging of alloy VT35 with β-phase are plotted for sheets without work hardening and for sheets with an initial β-structure subjected to cold rolling.[PUBLICATION ABSTRACT]
