This paper proposes criteria for the optimal choice of a database management system (DBMS), based on the requirements to this system. Empirically assessed criteria and method of analytic hierarchy process for decision making were used to carry out the comparative analysis of several DBMSs, implementing relation data model and having similar functionalities. The obtained matrixes of pair-wise comparison are examined for concurrence by calculating indices described in the article. As a result, the database management system for the own project is rationally chosen.

Universal method of optimal control synthesis offers a versatile method for the synthesis of optimal controls provides a solution to the synthesis problem for the class of piecewise constant functions for Lagrangian dynamical systems, the shape of the control law depends only on the structure of the cost functional and does not depend on the structure of the existing system of generalized forces. The effectiveness of the method is confirmed by a minimum of computational costs, as well as the maximum rate of convergence and accuracy to achieve the desired trajectory in comparison with the known solution for example has become a test for testing various control methods for the synthesis problem of a simple pendulum.

The article highlights the issue of conservation of water and energy resources, the dependence of its decision on the environmental responsibility of business entities and tactical goals towards environmental management.  Also the essence of the work carried out in the production of ammophos is described (Hydrometallurgical plant, Lermontov town), which is a good example of solving one of the many tactical tasks in the direction of environmental management. Specific purpose of the work was to identify the savings reserves of energy and natural resources. The application object of the study is the energy-intensive production of ammophos (fertilizer complex of nitrogen and phosphorus compounds), in particular the boiling-down of ammoniated pulp. The load decrease by evaporated water by 75% is achieved the implementation of technical solutions in terms of sealing pumps work (replacing inefficient crevice seal on a metal face seal) installed on the circulation line of ammoniated pulp. This reduces the coolant flow for boiling-down of high pressure steam and drinking water saving, which is the raw material for the production of fluid. Ecological and economic efficiency of the proposed solutions is confirmed by the calculation of the expected technical and economic parameters, performed on the basis of data generated in monitoring: coolant saving - 3039 Gcal / y; 2430 rubles / g; drinking water saving - 11,477 rubles.

The paper describes the method for determining the position of the contact wire of electrified railways using microwaves. The method is based on the triangulation system of two georadars and allows to determine a contact wire zigzag and height from the rail head. The proposed method is all-weather with the possibility of continuous monitoring of the overhead contact wire in plan and profile with the opportunity to automate the processing and signaling abnormalities.

The main methods of Platycladus orientalis seed propagation are studied. For Platycladus orientalis industrial cultivation the following technologies of reproduction are recommended: For off-sort samples – seed propagation after stratification (25-30 days); For sorts and decorative forms:
1.Vegetative propagation using IAA.
2. Micropropagation of Platycladus orientalis in vitro by means of adventitious shoots induction on the MS medium adding 0,2 – 0,5 mg/l BAP. There are derived well rooted microshoots on the medium with IAA in concentration 5 mg/l.

The method of laser therapy is based on synchronization of phases of inflow (anacrotism) and outflow of blood (catacrotism) in the field of the pathological center with phases of a being narrowed and extending laser spot on a projection of this pathological center. It is supposed that being narrowed on a projection of the pathological center the spot of laser light stimulates blood inflow to the spot center, and the extending spot of a laser beam – activates blood outflow in the direction from the spot center to its periphery. The developed technique of the automated correction of hemodynamic frustration consists in pilot signal formation (in charge of the power and laser positioning) for the laser machine on the basis of a difference between a reference rheogram and a rheogram of the patient (a body site) in real time.The offered technique has to allow to use more efficiently methods of laser therapy at treatment of violations of a blood-groove. The technique is calculated on the basis of numerical experiment by means of methods of mathematical model operation.In the real experiment the question of synchronization of the reference and measured signal is considered solved though this task represents a subject of separate researches.The received pilot signal can be in real time transformed to the current signal operating positioning and laser power.The method gives the chance of an operating control of a condition of the patient and blood-groove diagnostics to, in time and after a session of laser therapy. Development provides possibility of adaptive individual correction and optimization of parameters of influence during a session and a course of treatment.

The aim of this work was to conduct monitoring and make a regression model of the microbiological air pollution in Volgograd near highways. The work carried out monitoring of microbial air pollution in the residential district of Volgograd near two major highways - first and second longitudinal lines. On the first phase of research the microbial monitoring of air pollution in the residential district of Volgograd was conducted, depending on the proximity to the highway. Number of microbial cells (MC) was evaluated by sedimentation. The assumption is made about the nature of the regression relationship between microbial air pollution and the distance from the highway. Approximating functions and regression coefficients are constructed for the first portion of the longitudinal line at different levels of traffic road. Function is obtained, which allows to calculate the value of microbial contamination of the air, depending on the distance to the road and number of vehicles. In the case of high levels of the microbiological monitoring of the basin air it’s necessary to carry out measures to reduce microbial contamination of the air, for example, regular watering roads, tree planting, vegetative barriers adsorbing pollutants, chemical treatment of disinfectants. The calculation of microbial contamination of the air near a residential building located at a distance of 10 meters from the highway in the central region of Volgograd is conducted using proposed in function prediction of microbial contamination. The developed technique allows us to make calculations without setting up experiments in a specialized microbiology laboratory.
