Dynamic analysis of threats priorities economic dimension of sustainable development administrative - territorial units of Ukraine

Dynamic model of the economic dimension in view of the threats identified and its characteristics for the local government area. The method of calculating the level of threat, which includes grouping sets of data for specific classification features that characterize a particular threat , to create a database for a certain period, the definition of inter depending on the components and the maximum level of threat, the calculation and analysis of the formation of recommendations. The dependence of the functions described and graphically represented in the work.

Increasing of the efficiency and serviceability of equipment of power plants and small engineering during variable mode of operation

The recommendation for designing of air dust-feeders, which ensurance uniform feed of dust to burners of the boilers when low-reaction coal is burnt in working conditions of 300 MW energy unit are worked out. The plan of the branch standard “The method directives for developing, designing and putting in practice of the system of dust feeding with high concentration (under the pressure) to boiler 300MW energy units, which burn low reaction coal” are prepared.

Bezklinkernye inorganic binders with care tonnage thermal power plants - ash and wall products based on them

The purpose of the research is to develop a inorganic binders based on tonnage waste thermal power plants and wall building products based on them.

In carrying out the work were identified pozzolan and hydraulic activity of ash of thermal power plants, depending on the temperature conditions of synthesis and chemical characteristics of the system. Find supplements activators that can adjust the speed of the processes of structure formation.

Development of high-energy and resource-saving technological bases of the processes of manufacture of constructional polymer composites

An important national economic problem related to the scientific substantiation of energy-efficient processes and equipment to produce plastic products reactors on the basis of improved formulations of epoxy resins reinforced with fibrous fillers, in the acoustic field of ultrasonic frequency, and the prediction of physical and mechanical properties of the resulting products is solved.

Technological processes of coating with surface modification by streams of comp rational plasma

Entering within the local areas of the surface portions considerable additional energy allows the creation of conditions for phase and structural changes in the material and in the case of special operating environments - and modify the chemical composition of the surface layer of the material . The additional energy is accomplished using a pulsed arc that is formed between one of the electrodes of the main flow of the plasma generator and the surface of the product.

Making technology and precision processing of new bearing materials with increased wear resistance based on alloy steels wastes

Developed technology and precision processing of composite self lubricant bearing materials for heavy duty exploitation conditions based on alloy steels wastes with solid lubricant allows to manufacture new parts which essentially exceed known bearings over wear resistance for analogue conditions. Created technology is based at use of powder technological operations in combination with fine machining of friction parts.

Development of theoretical and technological foundations of obtaining the modern multifunctional powder-constructive materials with participation of self-fluxing alloys

It is shown that promising to create a powder composite materials for constructional purposes and their products have a composition of iron and self-fluxing alloys (SFI). Based on the study of the processes of wetting of solid surfaces of iron and its alloys, the interaction between them, pressing and sintering processes proposed technological regimes and process for producing powder products for constructional purposes to work under high loads.

Elaboration and investigation of gas discharge equipment for electron impulse beam evaporation and ion-plasma deposition of nanostructurized coatings

Analyze of high voltage glow discharge with cold cathode and anode plasma, oriented to investi¬ga¬ti¬on the possibilities of using the high voltage glow discharge electron sources for elaboration the technological equipment for impulse electron beam evaporation and ion-plasma deposition of coatings have been provided.

Development of technology for production of nanocrystalline silicon films based on amorphous Si-Sn-C and control methods and the pn-junction structure

Developed and implemented technological scheme of low-temperature synthesis of nanocrystalline silicon films. The method of thermal vacuum deposition in a stream of high-energy electrons. Theoretical model of the thin-film photovoltaic based nanocrystalline silicon (nc-Si). The model takes into account the three-dimensional distribution of potential barriers.

Research and development of the technology of medical stents manufacturing by means of laser milling

We established that at laser stent manufacturing by means of direct laser milling technology there is a possibility to create “pockets” in the stent’s walls with given depth, shape and size. These pockets are used for drug deposition and could not be formed using ordinary laser cutting techniques. Moreover, it is also possible to wary the stent’s filament thickness (up to 20 mkm) thus increasing the flexibility and elasticity when filament’s width increases (from 0.5 to 1 mm).
