Fragmentation and Multifragmentation of 10.6A GeV Gold Nuclei

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 interac- tions, 5260 helium nuclei and 2622 heavy fragments were observed as Au projec- tile fragments. The experimental data are analyzed with particular emphasis of target separation interactions in emulsions and study of criticalexponents. Multiplicity distributions of the fast-moving projectile fragments are inves- tigated. 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 gamma, beta and tau 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.Comment: latex, revtex, 28 pages, 12 figures, 3tables, submitted to Europysics Journal

Professional foreign language competence formation using educational multimedia technologies

The purpose of the study is to analyze the use of multimedia teaching technologies as a means of developing future linguists' professional foreign language competence and to substantiate the effectiveness of their use in professional training. A combination of modern methods of pedagogical research has been used to fulfil the set goals: theoretical methods, such as analysis, generalization, comparison, synthesis, and systematization of scientific, educational-methodological literature, to determine the current state of the research subject; empirical and diagnostic methods (observation, conversations, interviews, questionnaires, testing) to determine the effectiveness of using multimedia teaching aids and determine practical recommendations for their use; prognostic methods to ascertain and diagnose the level of professional foreign language competence in future linguists; pedagogical experiments to experimentally check the effectiveness of the application of multimedia teaching technologies (multimedia educational presentations) in the process of developing the professional foreign language competence of future linguists; and methods of mathematical statistics for quantitative and qualitative processing of research results and statistical verification of their objectivity using the Pearson χ2 test. The usefulness of multimedia technologies in the development of future linguists' foreign language competence has been substantiated. The practical aspects of creating multimedia presentations aimed at developing professional foreign language competence have been described. It has been proved that the use of multimedia educational presentations to create a foreign-language communicative environment during future linguists' professional training will increase the level of linguists' independent acquisition of educational information, as well as provide positive motivation for educational and future professional activities. © 2021 Conscientia Beam.
