Mail: [email protected] Annotation. The characteristics of a highly sensitive express stand of non-linear-optical diagnosis of crystalline structures such as sphalerite by generation of the second harmonica are presented. The analysis of quantitative and qualitative characterization capabilities was carried out using the stand of features of crystalline parameters of layers of heteroepitaxial structures cdhHg1-xTe on substralis from GaAs with orientation (013). The results were obtained by deviations of orientation in layers from the orientation of the substrate, which arose during the epitaxy, to determine the existence of stresses. The high sensitivity of the stand revealed the presence/absence of micro-particles with a disordered crystalline structure. Experimental results of reversible modification of the "in situ" crystalline state of CdxHg1-xTe structures with short-term local radiation exposure of high power laser radiation are given. New experimental data have been presented showing that the components of the nonlineaic susceptibility tensor cxyz(w) of the crystalline structure of CdxHg1-xTe depend on composition and are an order of magnitude larger than similar components of tensor in CdTe and GaAs.

The article reviews the history of the founding of Novosibirsk State University in the context of the first years of Akademgorodok in Novosibirsk, the largest scientific center in the eastern part of Russia. It describes the logic of the formation of a system for training researchers: physic and mathematic School – University – institutes of the Siberian Branch of the Russian Academy of Sciences. The main characteristics of the principle "education through research" are presented along with the current status of the University and plans for the future.

The review analyzes the approaches of the well-known Russian historian A.V. Shubin to the coverage of the typology of revolutions and the features and chronology of the Great Russian Revolution of 1917 and the Civil War of 1918-1922. Alexander Vladlenovich Shubin is Doctor of Historical Sciences, Chief Researcher at the Institute of World History, Russian Academy of Sciences, Professor at Russian State University for the Humanities, author of more than 20 monographs and about 200 scientific publications on the problems of Soviet history and history of leftist ideas and movements.
