Fundamental bases of the organochemical leaching of the metals coloured, rare-earth and precious from mineral natural and second technogenic raw material

Investigation of the mechanisms of bioleaching minerals extractant can use their patterns for selective removal of target chemical elements. The estimation of possibility of organic acids to the reactions of lixiviating was executed after classic thermodynamics parameters – the change of energy of Gibbs (∆G0f), enthalpy of formation of reaction products (∆H0f), entropy of reaction (∆S0f), energy of activating of lixiviating process (Er), constant of equilibrium of reaction (Kr) and energy of crystalline grate of having a special purpose mineral (Ucryst).

The theory of structural-parametric geometric modeling as a means to optimize the complex processes of computer-aided design

Automated modeling is an effective tool for the design of high-quality technology and the processes of its production. The fundamental basis of information in engineering are geometric patterns that are formed using a variety of computer-automated systems.

Modelling of the formation and propagation of cracks in the construction of chemical equipment from operational factors

A theory of multi-shell systems to develop new methods that provide the ability to model the nonlinear deformation and fracture of shell systems through mobile and physically reasonable basis redefinition the expansion depending on the changes in physical - mechanical characteristics of the structure in the development process of zones of plasticity and fracture of layers of the investigated object. Has developed a new concept of the iterative construction of the functions of bringing a refined theory of multilayer shells and plates.

Research of structure formation processes and creation of the theory of intensive plastic deformation of aluminium-lithium and titanium alloys

Based on an analytical review of scientific publications the goal and general guidelines were grounded. The prospects of using structurally modified and structurally inhomogeneous materials based on titanium and aluminum alloys were shown.

The analysis of power loading schemes of isothermal extrusion was made. Typical schemes of loading as a result of structural and logical analysis were classified depending on the impact of shear stresses, which are proportional to the forces of friction, on the overall stress state in the cell strains.

Development of the special methods of theory of the field and perfection on their basis of spatial stochastic technological systems of metal-cutting machine-tools

Special methods of field theory, which are aimed at the study of vector and tensor fields of kinematic and dynamic parameters of the technological systems of machines. Methods used in studies of working systems machine tool spindles with cyclic changes of the field parameters. The laws of vibration field of one-dimensional and multi-dimensional continuum of dynamical systems tools. A fundamentally new method of description of stochastic spatial cutting forces in the form of a tensor field correlation moments of the projections of the random vector of the cutting force.

Development of scientific and methodical bases of structural foresight technology and recommendations about its use in innovative projects in Electromechanics

The determined compliance between a progressing variety of created by experts electromechanical objects and systems and element basis of periodic system of the electromagnetic field primary sources is established for the first time. It is scientifically proved that existence of such regularity is defined by the fundamental principles of genetic information saving of the complete elementary electromagnetic structures which genetic codes contain information both rather known, and potentially possible versions of structures which are allowed by the genetic principles of structurization.

Hydrodinamics and heat-mass exchange in steam-gas-fluid bubble exchangers

The theory of processes of hydrodynamics and heat and mass transfer is developed at a direct contact liquid and gas phases in the special terms of running bubbling layer, worked out by authors, that will be realized at a simultaneous serve in the tubular reactor of smoke gases and cooling water. In such reactor in the conditions of a limit space the relative high-rate of gas and liquid will be realized at providing of intensive interfusion of the last and continuous taking of the heated liquid from the active zone of reactor.

Investigation of passive evaporative condensing heat transfer systems to improve the safe operation of nuclear power equipment

Formulation and conduct of this work due to the urgent need to increase the security level of nuclear power equipment operations. The use of passive systems that operate mainly due to natural forces and phenomena and which include the heat transfer systems of evaporating-condensing type (ЕСT) will dispense with equipment at work which may refuse, reduce dependence on operator's actions during transients and accidents.
