Geoelectric modeling underground water objects
Orekhov A.A., Dorofeev N.V.
The geoelectric model of underground water objects is constructed in this work. The ecological condition of superficial and underground water objects can be estimated in real time by means of the systems of geoelectric control constructed on the basis of multipole electric systems. The constructed model is based on the analysis of transfer function of the geoelectric cut represented in the form of consistently connected RC-circuits. Change of transfer function values testifies to change of a chemical composition or a hydrodynamic mode of aeration zone and the first water-bearing horizon. The assessment of layers parameters – specific resistance and specific dielectric permeability – is made by means of the specialized algorithms applied to these purposes in geophysics. The presented geoelectric model is intended for further application in the system of environmental monitoring constructed on the basis of the geoelectric probing methods.
Keywords: environmental monitoring, gydrogeoecology, conductometry, geoelectric control, geodynamic object, conductivity.

Definition of structural steels machinability
Karpov A.V.
One of the important problems of mechanical engineering is to improve the workability of construction materials, including carbon and alloy steels. In this case, the quantitative characteristic of workability, as technological properties of the material is normal and is often difficult to realize in a variation of physical and mechanical properties of the material pieces within the party or non-guaranteed (and even unknown) properties of the workpiece material. Knowledge of the true values of workability will calculate the optimum cutting speed in the processing of procurement and thus ensure the best performance in compliance with the optimum period of life of the tool. The paper analyzes the difficulties of the existing approaches to machinability of structural materials and offers a new experimental method for rapid determination of workability, which is based on the use of specific indicators of cutting and simply implemented in the procurement department or mechanical plot. The proposed rapid method of avoiding costly and time-consuming tests showed good agreement with the reference values of the coefficient of workability of carbon and alloy steels brands.
Keywords: cutting materials, machinability of materials by cutting, cutting the specific work.

Increased reliability of geodynamic control system through the use of new techniques for measuring and monitoring
Dorofeev N.V., Orekhov A.A.
In this paper the method of increasing the reliability of the geodynamic control through the introduction of new methods of measurement and control. The proposed method is based on the equipotential geoelectric method to the registration of the phase characteristics of an elliptically polarized field and contactless transformer sensors. The proposed changes can not only get rid of the shortcomings inherent in the electric survey equipment, but also by elements of the measuring path redundancy to improve the reliability of the system. Schemes of combin-ing the elements of the measuring path of geodynamic control and graphics probability of failure-free operation of the system geodynamic control before and after the application of a technique. We show that the proposed method of measurement and control increases mean time to failure with probability 0.9, and 2.25 times of 6.75 years.
Keywords: geoelectric monitoring system, monitoring system, geo-ecology, geo-ecological monitoring, equipotential resistivity method, reliability, increased reliability.

Device for removing icicles on the perimeter of the roof of the building
Lieberman J.L., Gorbunova L.N.
Given reasons for the formation of icing on the roofs of the buildings at the temperature of external air from-1–2°C to 8-10°C degrees. Under the influence of solar radiation or heat produced from the roof, the snow melts, the water flows down to the edge of the roof, where, coming into contact with a cold surface, air, freezes and forms ice «cap». The ice here, gradually accumulating, forms the ice, from which in the subsequent «germinate» icicles. Icicles often fall, causing injury to people, damaging the roof, facades of buildings, con-structions, vehicles, destroying the drainage pipes, etc. There are the following main directions of preventing the formation of icicles: improvement of drainage of water from the roofs of buildings; decrease the intensity of snow melting on the main plane of the building roofs, gutters, etc.; reduction of the weight of snow, which can accumulate on the roof; the use of devices and devices for the removal of icing. Proposed device for removal of icicles on the perimeter of the roof of the building.
Keywords: icicle frost.

Quality assessment of the supporting surfaces in grinding prefabricated abrasive wheels

Abrasive processing is one of the most widespread modes of machining of constructional materials. The wide circulation of grind is promoted by development of new high-efficiency methods of processing (power, deep, high-speed etc.). Need of improvement available and creation of new technologies is caused by complexity of implementation of the process of grind in connection with non-stationary conditions of cutting. Now for the solution of problems of optimization of processes of grind, due to the lack scientifically reasonable data on communication of technological conditions with results of processing, the exclusively experimentally received sedate dependences of target parameters on grind modes are used. Thus, any solution of a problem of optimization is fair only for these experimental conditions and can’t be transferred on other conditions. In the real work questions of ensuring quality of a surface after grind by a modular abrasive circle are considered. Quality was estimated by means of curve Abbota.
Keywords: grinding, mathematical modeling, the temperature.

Stress tolerance of knowledge workers – an important component in enterprise management efficiency
Gorbunova L.N.
Stress-manual workers – an important component of the effectiveness of enterprise management In the conditions of scientific-technical progress in connection with the reduction of heavy and low-skilled manual labour and typical for modern professions combination of nervous tension with the «muscle hunger» leads to nervous and psychic stresses. A significant mental stress is considered as the main cause of neurotic shifts and the emergence of cardiovascular pathology in persons, employed in the system of enterprise management. In the article the characteristic features of the work of leading employees (the lack of physical activity and interpersonal relationships, lack of time for taking responsible decisions in extreme situations, etc.). With the increase of nervous tension increases total operating voltage of the organism, which can go into over-voltage, and in the subsequent to the development of production-related diseases and occupational stress. Recommendations are provided for the organization of work and rest during the day and the week of the senior staff and increase of their resistance to stress. We describe the physical and health-improving activities in the mode of work and rest, aimed at improving the efficiency, strengthening of health (basic standard forms of industrial gymnastics: introduction, preventive, restorative, etc.).
Keywords: hard work, illness, stress.

Improving the physical and mechanical properties of structural steel by volume of pulsed laser hardening
Pinahin I.A., Yagmurov M.A., Pinahin A.I.
In the article the need for different methods of strengthening materials to improve their physical and mechanical properties, mainly, such as strength and durability. Moreover, we show the feasibility of methods of strengthen-ing that improve the properties of materials by volume. The article gives a brief description of the method of volume pulse laser hardening, developed in the North Caucasian Federal University. Volumetric method of pulsed laser hardening previously used exclusively for cutting materials (high-speed steel, carbide), which showed positive results. Since previous studies have shown that in high-speed steels after volumetric pulse laser hardening is an allocation of cementite of the martensitic phase, further investigation was taken Armco iron, which contains almost no carbon. Results of the research suggest the effect of space pulse laser hardening of carbon-free materials.
Keywords: pulsed lazer processing, abrasive wear process, hardening of materials.
