1. Physical mesomechanics as an integration of continuum mechanics with physics of plasticity and strength (Part I) (page 7)
PASHAYEV A.M., JANAHMADOV A.KH.
The analytical overviewof studies in the new field of solid physics - physical mesomechanics of structurally inhomogeneous media, developing at the junction of the continuum mechanics (macro level) and the physics of plasticity and strength of deformable solid objects (micro level). According to the concept of structural levels of deformation, the surface layer of deformable solid objects is independent, and the leading functional subsystem. With increase ofdeformation level, it develops the autonomous processes (plasticity waves), which have a decisive influence on the plastic flow staging localization and the sample destruction in general. On the meso level, the deformation has a translational-rotational vortices nature.
The versatility of physical mesomechanics is due to the fact that it is based on the principle of gauge symmetry and it is analogous to other gauge theories such as Maxwell’s electrodynamics and general relativity theory.

2. Frictional interaction in electrical and thermal fields of metal-polymer friction pairs (page 30)
JANAHMADOV A.KH., VOLCHENKO A.I., PIRVERDIYEV E.S.,
VOLCHENKO D.A., VOLCHENKO N.A., ZHURAVLYOV D.Y.
The article studies the emergence and development of the electric and thermal explosions in the subsurface layer of the polymer linings and the discharge phenomenon that breaks the layer between the micro protrusions of the lining.

3. The fractal analysis of water-oil systems (page 54)
ISMAYILOV G.G., SAFAROV N.М., NURMAMEDOVA R.G., ALIYEV S.T.
On the basis of the experimental and theoretical studies, the authors investigate the possibility of using the fractal analysis to assess the structural changes in the oil-water systems. It is established, that the diagnosis of the structural state of the water-oil emulsions is purposeful in terms of the fractal analysis and can be used as a tool to study the dynamics of the disorganized systems, to which the water-oil emulsions belong.

4. Synthesis sealing of well packer seal (page 63)
MAMADOV G.V.
The paper develops the calculation techniques of the sealing rubber used in the oil-field equipment. The main calculation features are analyzed for the necessary constructive changes of sealing, which provide the realization of given mechanical characteristics.
For the synthesis sealing (down-hole packer) the elastic potential is applied, which is defined on the basis of the asymmetric shape of the seal, so that when the seal is compressedagainst the contact surface there would be a fixed voltage, filling the seat.

5. The international application of eor methods: experience and prospects (Part I) (page 74)
VOLCHENKO D.A.
The first part of paper reviews the existing methods of enhanced oil recovery (EOR) methods, their effectiveness, as well as their history and classifications.

6. The technological regimes management of the masut-oil pumping (page 83)
NURULLAYEV V.X., QAHRAMANOV F.S., ALIYEV S.T.
Authors review the possibilities of technological regimes management of masut-oil pumping. The optimum proportion of masut to oil mixture is establishedon the basis of experimental data,which is attained at the level up to 20%. It is shown that a technological regime of pumping should include themixing temperature as a necessary factor of mixing and experimental results of the mixture viscosity.

7. Working out of mathematical models drying natural gaz by preparation for transport (page 89)
GURBANOV A.N.
The hydrates formation model is developed inside of thecrude gas channels, it is based on the hydrodynamics and heat exchange equations in in the axes symmetry conditions. The account of two-dimensional effects of the hydrates formation allows specifying the initial point of the hydrates formation in pipelines.
The technique is developed to estimate the deposition of the condensed phase at the natural gas movement, using the results of the joint numerical solution of equations for the gas and condensed phases in two-dimensional statement. The calculation of particletrajectories in the technological equipment shows the possibility of either the abrasive wear of the details that are in a stream, or the intensive sticking and accumulation of the condensed phase.

8. Thermal stress calculations of the dock designelementsinhydraulic structures (page 97)
HASANOV E.E.
Dock structures that are widely used in hydraulic engineering are subject to various external pressures and influences. In this paper the thermal stress is calculated for the wall and the bottom of the docking chamber ship lock.

9. Environmental risks of water injection in old oil fields of Azerbaijan (page 107)
MURVATOV F.T., MAMEDOV F.M., MAMEDOV N.T.
Some ecological risks caused bythe water injection process at the old oilfieids isstudied in this paper and the use of more advanced methods which will maximize energy and resource savingfrom economic, technological and ecological standpoint is recommended.

10. Autonomous multi-contour systems of auto-control inelectric rolling stocks (page 113)
BAGIROV B.E., MANAFOV E.K.
The article examines the functional diagram of autonomous double-contour auto-control system with the regulating circuits on current and speed. The system has been developed for the automatic control of electrical trains, by placing these systems into the operation according to some indices, particularly the minimum expenditure of electrical energy. The operational conditions of electric rolling stocks are optimized.

11. Featuresof managementalgorithms in the agricultural sector of Azerbaijan (page 117)
ALIYEV B.H., ATABABAYEV E.R., RZAYEV R.R.
The numerical determination of the component weight based on the complete matrix, which is constructed on the basis of the management model diagram, seems by authors as an effective tool in the modeling of the adequate management system.The system classification in the post-reforming period, as a difficult period from the system management point of view, provides the methodological ground to choose any appropriate management model. A clear parametric description of the system makes it possible to perform the correcting classification, followed by the optimal selection of the management model.Expressed in numbers, the component weight allows an indicative prioritization of the investment policy.
