: We present the results of a study performed on the interactions of 10.6A GeV gold nuclei in nuclear emulsions. In a minimum bias sample of 1311 interactions, 5260 helium nuclei and 2622 heavy fragments were observed as Au projectile fragments. The experimental data are analyzed with particular emphasis of target separation interactions in emulsions and study of critical exponents. Multiplicity distributions of the fast-moving projectile fragments are investigated. Charged fragment moments, conditional moments as well as two and three -body asymmetries of the fast moving projectile particles are determined in terms of the total charge remaining bound in the multiply charged projectile fragments. Some differences in the average yields of helium nuclei and heavier fragments are observed, which may be attributed to a target effect. However, two and three-body asymmetries and conditional moments indicate that the breakup mechanism of the projectile seems to be independent of target mass. We looked for evidence of critical point observable in finite nuclei by study the resulting charged fragments distributions. We have obtained the values for the critical exponents γ, β and τ and compare our results with those at lower energy experiment (1.0A GeV data). The values suggest that a phase transition like behavior, is observed .
Bei der Umsetzung von l‐Vinylimidazol, 1‐Vinylbenzimidazol und l‐Vinylbenzotriazol mit den oben genannten Chloriden in alkoholischer oder aceto′ nischer Lösung entstehen metallhaltige Komplexe vom Donator‐Akzeptortyp, z.B. (I)‐(III).
We analyse the multifractal structure of moments Gq in
terms of a new variable X on data of 197Au, 32S and 16O
induced interactions with emulsion nuclei and Monte Carlo
generated samples. The dynamical properties of the produced particles
are mapped onto multifractal spectra. We compare ln ⟨G⟩
in experimental data of 197Au, 32S and 16O with pure
statistical fluctuations. It is shown that the stochasticity plays
an important role for the G-moments.
Academic mobility is one of the key directions of development of intellectual potential and realization of professional opportunities of both youth and highly qualified specialists, scientists and teachers. This category of the population is the intellectual potential of the country, able to carry out an “innovative breakthrough” of the economy, able to act as a mechanism for strengthening the integration processes in the Eurasian space (within the EAEU and SCO), as well as to become a certain reserve for the demographic development of some Russian regions. The term “circulation of minds” is defined, which has become increasingly used in relation to the emigration of specialists from Russia. The circulation of minds implies that the migration of highly skilled professionals and scientists follows the movement of capital and projects, is temporary and returnable. The concept of “academic mobility” is specified and its key characteristics are given. The evaluation of the implementation of international programs to promote academic mobility, including such programs as Erasmus Mundus, DAAD, Tempus, Fulbright Program, etc., which allow participating countries to obtain positive socio-economic, scientific and demographic effects. Unfortunately, this potential of educational migration is not fully realized in Russia. In addition, the Russian science lacks the necessary amount of scientific research on the problems of academic mobility, which is largely due to the negative “color” of educational migration in the country, due to the significant attention to the problem of “brain drain”. Nevertheless, in our opinion, Russia has enormous unrealized potential and unique opportunities for the development of academic mobility. In conclusion, there are proposals for the formation of Russia’s policy in relation to the development of academic mobility, maintaining a positive trend to attract highly skilled migrants from near and far abroad, but also for the further development of forms of academic mobility.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
