Congratulations (page 6)

1. Self-control and control of internal and external parameters in metal-polymeric frictional couples of band-shoe brakes (part 3) (page 10)
VOLCHENKO N.A.
The paper illustrates the static and dynamic control of the unit loads in the standard and multi-couple frictional joints of band-shoe brakes of a draw-works.

2. Increase of machine parts and equipment reliabilities by rolling method (page 22)
GAFAROV A.M., SULEYMANOV P.H., GAFAROV V.A.
The aspects of machine parts and equipment fatiques working under extrimal conditions are reviewed in this paper. The methods of surface plastic deformation are investigated, such as technological method, which increases th relibaility of machine parts towards various forms of destruction, fatiques coloring and other forms of fatique. The impact of different parameters of the rolling process on the quality of the high-precision nationaly manufactured machine parts and equipments, working under extremal conditions, is analyzed.

3. Factors effecting on heating of elastic element of connecting couplings (page 34)
KHALILOV I.A.
The article investigates the heating of elastic element in the connecting coupling, depending on factors such as the damping capacity of the coupling, the ratio of the moments of inertia in drive and driven branches of actuator, the heat exchange coefficient and the cooling area of the elastic element of coupling, as well as the circumferential oscillation frequency of the machine driving system.

4. Mathematical model development for oil filtration process in reservoir with skin-factor effect (page 43)
RZAYEV A.G., RASULOV S.R., ABASOVA I.A., RAGIMOVA S.N.
The paper proposes a modification of the Dupuis formula that describes the filtering process with the skin-factor effect at the contaminated oil-well zone. The correctness of solution is shown.

5. Uniqueness of geological, physical and operational conditions of the Siazan oil field monocline (page 47)
MURVETOV F.T., KERIMOVA A.Q.
The article examines the uniqeness fo geological and physical conditions of the Siazan oil field monocline, and different complications arising in the field due to technological operations on complition. It is recommended to use interspaced filters instead of long filters to boost an operation efficinecy.

6. Study of two-phase flow system such as “water-oil” in pipe (page 54)
SALAVATOV T.SH., DADASH-ZADEH M.A., KYRDODA I.I., BABAEVA T.S., SALAVATOVA R.SH.
A new model of the emulsion flow system is suggested based the laboratory and field data, the techniques to determine their main parameters are developed. Based on this methodology, a formula to calculate the dynamic viscosity of such systems is found.

7. Aviation fuel monitoring during contemprorary transportation and storage (page 59)
NURULLAYEV V.X.
The paper’s author reviews the possibility to regulate the general parameters of national and foreign transportation aircrafts, and also parameters of civil aviation aircrafts tested on the aviation fuel. The physical and chemical analysis of the Azerbaijan oil products, TC-1, is conducted in accordance with standards of GOST 10227-86 and ASTMD 1655-02. The transportation and storage of aviation fuel under the international regulations is shown on the basis of experimental studies.

8. Unsaturated synthetic and natural organic acids, their derivates and application (page 67)
ABBASOV V.M., RZAYEVA N.M., ALIYEVA L.I., MAMEDKHANOVA S.A., TALIBOV A.H.
Sulfonic acids has been studied on the basis of fatty acids extracted from vegetable oils, their physical-chemical properties and ability to dissolve in various solvents have been examined. Sulfonic acid was used to obtain salts and complexes, its inhibitory activity in 1% NaCl aqueous solution saturated with CO2 were revealed. The gathered data showed that, based on unsaturated organic acids also including those obtained from plants, semi-functional and highly effective corrosion inhibitors and other protectants can be created.

9. Synthesis and application of macrocyclic compounds with quaternary ammonia centers for improving rheological properties of oils (page 81)
RZAYEVA L.T., MIRALAMOV H.F., MAMEDOV CH.I.
Taken into account the large theological significance of quaternary ammonium compounds in the oil industry, the paper’s authors have developed the unique method of synthesis of the macro-cyclic compounds with quaternary ammonium in the center of ring. Syntheses are carried out on the basis of easily accessible 2.21-digalogend alkyl ethers and bis-tertiary amine.
The resulting regulators reduce viscosity of heavy oil and reduce the amount of petroleum resins.

10. Modeling of human-operator decision process in socio-technical air navigation system (page 88)
JAFARZADE T.R., SHMELOVA T.F., SIKIRDA Y.V.
The socio-technical analysis of the air navigation system has been conducted, as result the various factors affecting on the human-operator decision process under expected and unexpected aircraft operating conditions are classified, formalized and systematically summarized. The base models are obtained for the civil aviation pilots and controllers to investigate the influence of socio-psychological and individual-psychological factors on their professional performance. The influence of preference system of the civil aviation pilots and controllers on their conceptual behaviour is determined.

11. Instrumental measuring of aircraft vertical speed based on magnetic levitation (page 103)
BADALOV A.Z., NABIYEV R.N., MAMMADOV A.Z.
The aim of this work to propose an appliance schema for measuring an aircraft vertical speed based on the concept of magnetic levitation. The aircfract velocity is displayed on the digital monitor. The schematic diagram of device can be singled out due to a simplicity of its circuit design. The functional block-diagram and its calculation are provided in the paper. The actual software to calculate and display speed is also developed.

12. Methods to reduce fuel losses in civil aviation fuel supply (page 110)
PURHANI S.H., MEKHTIEV J.S., GULIYEV R.E.
The article examines types and reasons of aviation fuel losses as well as methods of their reduction. Different approaches are suggested for feasibility studies to assign technical means of fuel loss reduction.

13. High-resolution space radar to determine oil pollution parameters in the Azerbaijan sector of Caspian sea (page 119)
MEKHTIEV A.SH., AZIZOV B.M., BADALOVA A.N., SULTANOV J.A.,
MEKHTIEV J.S., RAMAZANOV K.SH.
The paper examines the radar satellite data from “Radarsat-2″ to determine the oil pollution parameters in the Azerbaijan sector of the Caspian Sea. On the basis of analyzing the radar images, the information on main sources of pollution, their dynamics and parameters, and valuation of objects of technological effluents. Although, by using radar data obtained maps provided the boundary of the distribution of the oil slick in the Caspian sea.
