The possibility in principle of using pulp and paper industry waste as a binder for pelletization flotation potassium chloride bases on conducted researches. Defined technical conditions of pelletization flotation potassium chloride using pulp and paper industry’s waste as binder provide product with good commercial qualities, which are yield of marketable fraction (85.71 %) and resistance of granule (29.51 N). The researches for studying conditions of baking were conducted and subsisted defects on granule surfaces. There are two kinds of defects. One of them is inner defect is represented as caverns and flaws. Another type of defects are outer defects. They are represented as crystallized structural arrangements in the form of coreless tube that has net structure and includes fiber and cubic shaped microcrystals. Granule defects form after baking them with temperature higher than 120ºC.

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.
