Заглавие документа: Influence of Natural and Climatic Factors on Water Horizons Protection Degree in Site Evaluation for Radioactive Waste Disposal Авторы: Harbachova, N. V.; Kuzmina, N. D.; Kulich, N. V.; Yatsko, S. N.; Korchova, J. A. Аннотация: In this paper, natural (geological and hydrological) and climatic impact conditions on the influence zone for two different sites of radioactive waste disposals have been studied. Probabilistic approach to assessment of the groundwater vulnerability from radionuclide contamination during disposal of radioactive waste is developed. As to climatic conditions, an effective numerical and analytical methods for annual precipitation rates assessment of rare recurrence have been proposed which allow to take into account uncertainties of rare events as well.

Заглавие документа: Collective Behavior of Secondary Particles in the Region of high Multiplicity in pp Interactions at 50 GeV/c Авторы: Kokoulina, E.; Barlykov, N.; Dudin, V.; Gribovsky, A.; Dunin, V.; Nikitin, V.; Popov, V.; Kutov, A.; Ryadovikov, V.; Shulyakovsky, R. Аннотация: The latest results on the search for collective phenomena in proton interactions at the U-70 accelerator at IHEP (Protvino) are presented. This long-term experiment has been carried at the SVD-2 setup. Our study was aimed at a high multiplicity region where the series of collective phenomena is predicted. We have received an evidence of the formation of a pion (Bose–Einstein) condensate. We have observed two noticeable peaks in the angular distribution of charged pions interpreted as Cherenkov radiation of gluons by quarks and others phenomena.

Заглавие документа: The Discrete and Continuous Quantum Field Theories and Natural Ultraviolet Cutting-off Авторы: Shalyt-Margolin, A. Аннотация: Based on the results from black hole thermodynamics at all energy scales, this work demonstrates that, both for the discrete QFT previously introduced by the author and for QFT in continuous space-time, there is a natural ultraviolet applicable boundary (cutoff) distant from the Planck scales. It is important that this boundary exists irrespective of the fact in which pattern, perturbative or non-perturbative mode, QFT is studied. Different inferences from the obtained results are discussed, some statements are revised.

Заглавие документа: One-Dimensional Nonlinear Parametric Instability of Inhomogeneous Plasma: Time Domain Problem Авторы: Gerasimenko, N. V.; Trukhachev, F. M.; Gusakov, E. Z.; Simonchik, L. V.; Tomov, A. V. Аннотация: A numerical one-dimensional model of convective parametric instability of inhomogeneous plasma is developed. By using this model, a numerical solution describing spatial and temporal characteristics of interacting waves is obtained. The results obtained are in a good agreement with known analytical models and substantially generalize them. In particular, an important advantage of the proposed model is the possibility of varying initial conditions, analyzing behavior of the system in the presence of incident wave fluctuations that is important for the future study of the absolute instability mode. The model is also provides possibility to simulate absolute parametric instability with a wide range of controllable parameters, as well as to study interacting wave transients.
