The midrapidity transverse momentum [Formula: see text] distributions of the charged pions and kaons, protons, and antiprotons, measured by ALICE Collaboration at nine centrality groups of Xe[Formula: see text]Xe collisions at [Formula: see text], have been reproduced quite well using simultaneous (combined) minimum [Formula: see text] fits with the simple (non-consistent) as well as thermodynamically consistent Tsallis function with included transverse flow. The parameters [Formula: see text], [Formula: see text], and [Formula: see text] extracted in this work using both consistent and non-consistent Tsallis function with included transverse flow demonstrate the similar dependencies on collision centrality [Formula: see text]. The obtained non-extensivity parameter [Formula: see text] values decrease systematically for all studied particle species with increasing Xe[Formula: see text]Xe collision centrality, indicating an increase in degree of system thermalization with increasing centrality of heavy-ion collisions. The average transverse flow velocity demonstrates significantly different growth rates in regions [Formula: see text] and [Formula: see text], and parameter [Formula: see text] stays constant within uncertainties in [Formula: see text] range in Xe[Formula: see text]Xe collisions at [Formula: see text]. It is argued that [Formula: see text] could possibly be a threshold border value for a crossover transition from a dense hadronic state to the QGP phase (or mixed phase of QGP and hadrons) in Xe[Formula: see text]Xe collisions at [Formula: see text]. Depletion (enhancement) of [Formula: see text] ratio at low [Formula: see text] (intermediate [Formula: see text]) has been observed in this work in Xe[Formula: see text]Xe collisions at [Formula: see text], which agrees with the similar results of ALICE Collaboration obtained recently in high-energy Xe[Formula: see text]Xe and [Formula: see text] collisions at the LHC. Analyzing and reflecting the extracted [Formula: see text] versus [Formula: see text] and [Formula: see text] versus [Formula: see text] dependencies, we have verified that the depletion (enhancement) of baryon-to-meson ratio at low [Formula: see text] (intermediate [Formula: see text]) values with increasing [Formula: see text] is due to radial flow effects.

The formal oxidation potentials of the Bk(IV)-Bk(III) pair have been measured and the stability of Bk(IV) in 1 -10M sulfuric acid solutions has been investigated. The rate constants of the self reduction of 249 Bk(IV) in these solutions have been determined.

Research into the fluctuation of pseudorapidity distributions of secondary particles, produced in interactions of hadrons and nuclei of primary cosmic radiation at energy values of more than 1 A TeV by the normalized range method is carried out. Results of the analysis allow us to assert that there are events in which considerable multiparticle correlations are observed.

Abstract. In this paper we estimate changes of Russian higher education, aimed to incorporate In this paper we estimate changes of Russian higher education, aimed to incorporate the latter in the Bologna process. The analysis of the reforms is given in terms of need in training specialists of the construction industry. The article analyzes the conclusions reached on the issue by some teachers of Russian universities of civil engineering. Among the reasons for concern from the part of the Russian education community, it is called the low level of knowledge about the tasks of reforms and lack of information regarding measures to improve the education system. The investigation, in particular, points out that today the main issue of reforming is seen in creation of a single European intellectual space. At the same time, the questionnaire showed that the achievement of the stated purpose is prevented by the following factors: low level of student-builders in foreign languages and insufficient income. These circumstances make education abroad almost impossible for most students from Russia and reduce the competitiveness of graduates from Russian universities in labor market of the countries that joined to the Bologna system. The authors of the article pay special attention to the needs of executives of construction firms in qualified specialists. Most of the experts note the isolation of universities from solving problems of building practice, a noticeable lag of the national educational system from the western ones in training specialists in construction logistics and organization of construction sites.
