Purpose of the study: The need for knowledge, skills, expanding the established functionality of a professional is increasing more and more. That is why young professionals-trans-professionals, who are able to realize themselves not only in one sphere but who are ready to delve into problems of other, absolutely "foreign" for the scientific and technical fields and cooperate effectively with specialists of these areas in one team, will be responsible for creation of new technologies determining the wellness of our country. The article is aimed at the analysis and generalization of foundations of the convergence and identifying its sense-creating content in the development of trans-professionalism as an integral characteristic of the activity subject in a rapidly changing social-professional environment. Methodology: The leading methods in the study of this problem are the theoretical and methodological analysis of the subject and the problem of the research based on the study and logical generalization of scientific literature.

Improving the process of development of trans-professional competencies of activity subjects is associated with the development of new technologies - tools and methods

Study of Reduced-Enrichment Uranium Fuel Possibility for Research Reactors

Having analyzed the results obtained in the work, it is possible to conclude that the flux density of fast and thermal neutrons in the shell of fuel elements in EFA in REU-zone decreased on average by 5% for UO2 fuel and by 7% for U9%Mo fuel. Change of neutrons flux density during the cycle does not exceed 4% for both fuel types. On average the fuel burnup in reactor core during the cycle for UO2 and U9%Mo increased by 2.8%. It is 1% less that in HEU-zone, which is conditioned by higher initial loading of 235U in fuel assembly with REU fuel

THE FLORA OF FROM AULIEKOL DISTRICT (REPUBLIC OF KAZAKHSTAN)

For the first time data are given on the species composition of vascular plants in reservoirs located in Auliekol district (Republic of Kazakhstan). The flora studied includes 106 species belonging to 84 genera and 36 families. The absolute majority of species found in the studied associations are aborigines. Among them, the species typical of the forest-steppe and steppe zones (68 species) prevail with a wide distribution in the temperate zone of Eurasia-European-West Asian, Eurasian and East European-West-Asian. The group of alien plants is extremely small and has 9 species (8 %). The group of species associated with water associations is not numerous and is represented by 20 species. The most multispecies are groups of species of coastal associations: steppe, meadow and halophyte

Potential of Antifungal Drugs as Photosensitizers

In the present work, using commercially available formulation of polyene antifungal antibiotic amphotericin B, it is shown that its antifungal activity could be enhanced in combination with optical radiation corresponding to the absorption band of amphotericin B due to photodynamic effect. It is assumed that the radical processes dominate in the mechanism of photodynamic action in the presence of amphotericin B.

Peculiarities of sub-barrier fusion with quantum diffusion approach

With the quantum diffusion approach the unexpected behavior of fusion cross section, angular momentum, and astrophysical S-factor at sub-barrier energies has been revealed. Out of the region of short-range nuclear interaction and action of friction at turning point the decrease rate of the cross section under the barrier becomes smaller. The calculated results for the reactions with spherical nuclei are in a good agreement with the existing experimental data.Comment: 11 pages, 5 figure

Biological Effect of Continuous, Quasi-Continuous and Pulsed Laser Radiation

In this work, for the first time, comparative studies of biological activity of low intensity continuous, quasi-continuous and pulsed laser radiation of nano- and picosecond time ranges with the same average power density are carried out. It is shown, that, despite the significant differences in peak values of intensity of acting factor, both continuous and quasi-continuous radiation and radiation of nano- and picosecond ranges are able to have both stimulating and inhibiting effects on all investigated parameters of functional activity of biological systems in a certain range of dose rates. The ability of laser radiation of near infra-red spectral region (800 - 1340 nm) located out the absorption bands of main chromophores of cells to have regulatory effect on biochemical processes that control the hatching of branchiopod crustaceans Artemia salina L. upon irradiation of their cysts is revealed. The role of molecular oxygen and water as acceptors of laser radiation is discussed.

Sub-barrier capture with quantum diffusion approach: actinide-based reactions

With the quantum diffusion approach the behavior of capture cross sections and mean-square angular momenta of captured systems are revealed in the reactions with deformed nuclei at subbarrier energies. The calculated results are in a good agreement with existing experimental data. With decreasing bombarding energy under the barrier the external turning point of the nucleusnucleus potential leaves the region of short-range nuclear interaction and action of friction. Because of this change of the regime of interaction, an unexpected enhancement of the capture cross section is expected at bombarding energies far below the Coulomb barrier. This effect is shown its worth in the dependence of mean-square angular momentum of captured system on the bombarding energy. From the comparison of calculated and experimental capture cross sections, the importance of quasifission near the entrance channel is shown for the actinide-based reactions leading to superheavy nuclei.Comment: 11 pages, 16 figures, Regular Articl

Neutron Rich Hypernuclei in Chiral Soliton Model

The binding energies of neutron rich strangeness $S=-1$ hypernuclei are estimated in the chiral soliton approach using the bound state rigid oscillator version of the SU(3) quantization model. Additional binding of strange hypernuclei in comparison with nonstrange neutron rich nuclei takes place at not large values of atomic (baryon) numbers, $A=B\leq\sim 10$. This effect becomes stronger with increasing isospin of nuclides, and for "nuclear variant" of the model with rescaled Skyrme constant $e$. Total binding energies of (Lambda)He-8 and recently discovered (Lambda)H-6 satisfactorily agree with experimental data. Hypernuclei (Lambda)H-7, (Lambda)He-9 are predicted to be bound stronger in comparison with their nonstrange analogues H-7, He-9; hypernuclei (Lambda)Li-10, (Lambda)Li-11, (Lambda)Be-12, (Lambda)Be-13, etc. are bound stronger in the nuclear variant of the model.Comment: 8 pages, 4 tables; amendments made, data on binding energy of (Lambda)He-8 and references added; prepared for the conferences Quarks-2012 and HYP201
