A modern trend of scientific publications development shifts toward the network environments to an even more considerable degree. In practice, the new culture of the scientific publications is forming on basis of the global and mini Internet-platforms. The discussion of the comprehension experience and overcoming the different rating problems is suggested in the context of a science webzine “Engineer bulletin of Don”. It is observed that as the position of science webzines becomes stronger in the common space of the science magazines, there is a tendency to revising their evaluation criterion. Besides, the implementation of rates or coefficients prevails, the applicability of which relative to the science webzines is exogenous, i.e. it disclaims the aims of the science webzines. The application of restrictions, worked out within the framework of the traditional paper book-printing technology, is indicated to be unpromising. A new level of the science environment systemacy is suggested to be supplemented with the formalization of scientific evaluation rations, already existing and successfully maintained de facto, within the framework of the webzines – the Internet-platforms.

Background. Methods vibrodiagnostics allow to identify the emergence and development of de-fects at an early stage. Of particular relevance is the use of vibrodiagnostic methods for condition monitoring mechanisms under the simultaneous influence many unpredictable factors, varying operating conditions. The vibration causes blurring the boundaries of the focused image, allow-ing you to build a simple compact optical vibration sensor. (Materials and / or methods). Vibro-diagnostics used method for detecting focused optical im-age nodes being monitored. Determination of vibration parameters produced by wavelet analysis of the luminance distribution boundaries of the focused image. (Results). It is shown that the periodic movement of give in the image boundaries bends function (maxima of the second derivative). Character kinks function determined by the change speed of the change of the image boundaries. Continuous wavelet transform of the luminance distribution on the border of the image at a certain level amplitude vibrations cause the appearance of two maxima curves continuous wavelet transform, the amount of which is reduced proportionally. (Conclusion). Theoretical and experimental studies have shown that the optical image registra-tion allows you to register with the sensitivity of the vibration amplitude of 0.1 - 0.15 pixel ma-trix photo detector. For a pixel size of about 5 microns, a linear increase in the order of the opti-cal system 20 sensitivity in amplitude of vibration may reach values of 0.02 microns, which cor-responds to the sensitivity is achieved by holographic interferometry.

At present an important role in solving energy conservation problem is assigned to thermal pumping plants (TPP). Using processes of evaporation and condensation of easily boiling liquid circulating in the system they extract low potential heat from environmental objects and provide heat supply for buildings, constructions, greenhousee and so on. Artificial sources of low potential heat for TPP of different capacity can be, for instance, ventilation air and exhaust gases, circulating and waste water,ground. Energy efficient reasonability of TPP use in the system of water disposal for the town of Novocherkassk in Rostov region is considered. Calculations indicate that there is a technical potential to replace a boiler house operating on expensive gas fuel and emissing into the atmospere more than 850 t of carbon dioxide - greenhouse gas - with ecologically clean TPP, one of which uses heat of waste water and the other - heat of ground.

The article highlights the issue of conservation of water and energy resources, the dependence of its decision on the environmental responsibility of business entities and tactical goals towards environmental management.  Also the essence of the work carried out in the production of ammophos is described (Hydrometallurgical plant, Lermontov town), which is a good example of solving one of the many tactical tasks in the direction of environmental management. Specific purpose of the work was to identify the savings reserves of energy and natural resources. The application object of the study is the energy-intensive production of ammophos (fertilizer complex of nitrogen and phosphorus compounds), in particular the boiling-down of ammoniated pulp. The load decrease by evaporated water by 75% is achieved the implementation of technical solutions in terms of sealing pumps work (replacing inefficient crevice seal on a metal face seal) installed on the circulation line of ammoniated pulp.
