The results of scientific studies of the synthesis of hard alloys based on the model of sintering of hard alloys are presented. A library of mathematical models and a system of e-learning system for management of processes of obtaining hard alloys are developed.

The article is devoted to mathematical modeling of the process of regeneration of granular filter material from oil by aqueous solution of surface active agent. The regeneration process was carried out under laboratory conditions. Experimental data characterizing macrokinetics of filter regeneration have been derived from accumulation of particles of petroleum fractions carried out of the filter with a washing liquid. According to these data, kinetic curve of temporal variation of the average film thickness of contamination was plotted.

The paper presents mathematical models, a process of selection of an optimal structure and parameters of a pulse measuring transducer.

The article describes a method for inducing carotenogenesis in the yeast of Phaffia rhodozyma strain Y2228 using hydrogen peroxide.

The article describes the superdispersed and nanostructured metal fuel, oxidants and combustion modifiers for better combustion characteristics and performance of pyrotechnic low-gas compositions. The authors studied the dependence of combustion characteristics (voltage, current, time characteristics and burning rate) of a pyrotechnic element from the nature and content of ultra-and nanoscale powders of aluminum, boron, iron oxides and copper obtained by the method of arc plasma decanting.

The paper considers the possibility of combustion calorimetry method for determination of mass fraction of a substance in metal fuel and shows disadvantages of methods established by the normative documentation. Method of sample preparation, conducting the experiment and the mathematical processing of measurement results are worked out. Efficiency of the developed method has been confirmed by experimental results of analysis of superdispersed and nanostructured metal fuel.

The paper provides comparative analysis of bioconcentration levels of metals in body and formation of micronuclei in cells of Asterias rubens L sea stars coelomic fluid under the influence of mixture of iron, lead, copper and cadmium in normal (25,7‰) and low salinity (21‰), as salinity can significantly affect the expression of toxic properties of substances. Low salinity increases genotoxicity of metals and disrupts the immune response. There were not observed any significant differences in the level of bioconcentration in different salinity conditions.

The process of collecting suspended in vapor phase droplets and effect of various factors on the efficiency were discussed in the paper.

The article describes working substances that meet the requirements for use in high-temperature vapor compression heat pumps, which work on the reverse Rankine thermodynamic cycle. The comparison of the thermodynamic efficiency of working substances in the temperature range of single-stage heat pump distiller was made.

This paper describes the application of a low-temperature cooling. The most relevant schemes of low-temperature coolant for needs of cryochemical technologies using refrigeration gas Stirling machine were shown.

The technology of production Agrostis stolonifera lawn grass resistant to salts of lead was developed. For the production of plants tolerant to lead the direct selection circuit was used. This circuit compromises culturing the callus over two passages in the modified MS medium with 650 mg/l of lead, regeneration and rooting plants on MS medium with 650 mg/l of lead. The obtained plants remained high decorative quality at high concentrations of lead and may be used as starting shapes upon receipt of varieties tolerant to this metal.

The substantiation of the need for environmental policy in the management of industrial activity was proposed. There were proposed the model and the basic tools of enterprise management on the principles of environmental safety. Comparative assessment indicators were summarized, system for calculating environmental and economic efficiency was identified. All the results work when starting a new production and during subsequent modernization. Recommended innovations were tested at industrial plant. Analysis of the results confirmed the effectiveness of the use of innovative methods of management. Numerical indicators that determine economic impact by improving manufacturing operations in the monetary and material terms are shown.

Hazardous chemicals (HC) with enterprises into the soil and accumulate it. As a consequence, fertility of contaminated soil is reduced and the risk of chronic and serious diseases increases of population when using for agricultural purposes. When the chemical analysis on content of HC in soil the most time consuming is the operation of sample preparation, the implementation of which depends on availability of appropriate methodologies, and on staff qualification. To select the method of argumentation and workflow preparation of soil samples, there is developed algorithm allowing preparation of soil samples of unknown composition for analysis for presence of HC in conditions of absence of a priori information about the sample.

The experimental research minicircular nozzle type MCS. It has been shown that it may be useful in a number of column heat and mass transfer apparatus.

The limiting options to improve the efficiency of the production of carbon black for recycling schemes with and without recirculation of the exhaust gas into the reactor. "Limit" is evaluated in terms of the use of an idealized model, which does not take into account the carbon gasification reaction products. For optimization the use of economic optimality criterion. An interpretation of the conditions obtained optimal management of technological regime of the reactor, taking into account the impact of the regime in power consumption.

A combined contact device, consisting of a cap plates and blocks regular mesh heads, the technique of calculations of columns based on it.

The results of development of information system for calculate estimates of health risk. The application for early diagnostics of type 2 diabetes.

The existing lighting system offices usually perform tasks relay control - turn on/off lights. More intelligent systems allow you to set the desired light level, but require expensive equipment. The system continuously maintain the level of illumination on the basis of cheap component base.
