We propose a method for cooling the condenser compression refrigerator, including the use of melt water wetting the surface of the water condenser. The water is directed into the groove in the middle part of which is the tube condenser coil, and the water flows by gravity to the tribes of the inclined groove, wetting the surface of the trough and tube condenser. Remains of meltwater routed to the tank on the compressor.

  Modelling results of technical state of long-operated bridge crossings across conveyance structures are given in the article. As a result of the experiment a solid-state model for bearing element of a bridge crossing across conveyance canals was constructed. The stress-strain state of ferroconcrete bearing elements under various load combinations is considered. As a result of numerical experiments carried out zones of forming defects and damages on bearing elements of bridge crossings across conveyance canals were marked out. These zones may have characteristic damages of the same type that makes it possible to regulate the process of laying georadar sounding profiles and defining points in which it is necessary to measure concrete strength when conducting inspections on location. In this connection modeling defects on a column by way of formation voids and ferroconcrete unseals with diameters from 50 mm to 100 mm was carried out. Intensive danger threshold for forming voids and ferroconcrete unseals beginning from 100 mm diameter was fixed.

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.

The article is devoted to the analysis of modern trends in the development of methodology, theory and techniques of biotechnology. A methodological crisis and the clear need for reflection on the consequences of scientific and technological progress in general, and the application of biotechnology, in particular, led to the emergence of socio-methodological discourse of innovative approaches and concepts in this field of knowledge. One of the central provisions is sociosynergetic methodology, modelling the self-developing systems. Considerable attention is given to justify the inevitability of ethical-anthropological evaluation of the implications of the use of axiological biotechnologies. The author concludes that in post-non-classic methodology in general and in sociosynergetics, in particular, the bioethical principles, forming a new ethos of biotechnologies, will serve as a methodological rule. In connection with it, the search for mechanisms of introduction of qualitative bioethics practices is extremely important.
