The method of definition distribution Fisher-Tippeta parametres of final volume population (Ас, Вс, Сс) under the selective data of the average stress is offered in the given work. Average values of parametres (Ас, Вс, Сс) thus is recommended to use at repeated modelling. Thus the Ас, Вс, Сс received is recommended to use average values of parametres at repeated modelling.

Combined method which allows analyzing parameters of the nanoscale atomic and electronic structure of materials relying on three different methods (x-ray absorption spectroscopy (XAFS), x-ray diffraction (XRD) and Raman spectroscopy) was developed. The method was applied for the study of nickel oxide nanoparticles, which serve as an efficient catalyst for the artificial photosynthesis process.

We have carried out the analysis on the scientific and technological literature on methods of calculation and analysis of the x-ray diffraction, x-ray absorption and Raman spectra used to analyse the structure of the materials for hydrogen storage under realistic operating conditions. The simulations were carried out for the series of small palladium nanoclusters with embedded hydrogen. Multiscale computer modelling was used to simulate the dynamics of structure of the materials during charge/discharge phases.

Project financing provides an efficient allocation of risks between key counterparties of project initiatives, which are best suited and have the most appropriate instruments to cover this risks. The study of structural and operational principles of project financing risk management instruments: contractual arrangements and associated guarantees (turnkey (engineering, procurement, and construction) agreement, contractual structures of the operating period: offtake / procurement agreements, operation and maintenance agreement), contingency funds, cash trap, risk compensation devices, derivative contracts and insurance – allowed to reveal specifics of their application and assess their implication for mitigation the project financing risks and for success of the project financing initiatives.

Contract organization of project finance allow to reduce the asymmetric information, limiting the possibility of opportunistic actions of each participant. The back-to-back principle, that is underlying for contractual arrangements, increases total project return and provides transfer and split of highest possible number of risks directly to the contractual counterparty, which is best suited and have the most appropriate instruments to cover this risks. Tripartite deeds of project financing can be considered as a cooperative non-zero sum game, which provides compensation in proportion to covered risk and member's contribution (extent of assumed obligations or provided funds). Multiple contracts of project finance initiatives allow to allocate risks pro rata the ability of participants, without reducing the amount of final win of all parties.

It was investigated the influence several additives and process parameters on the properties of piezoelectric ceramics based on PZT phase systems. It was shown that the use of the substitution of Pb2+ ions on the Bi3+, and Ti4+ ions, and Zr4+ to Fe3+ and Mn4+, as well as the method of "chemical assembly «allows to obtain increase the Curie temperature of ceramic samples of 50 - 170°C. The theoretical aspects of this area of research have been discussed in this article.
