In this article analog device capable to make portion of different functions in wide frequency band is discussed. Some recommendations for possible application examples are offered.

The paper considers the system of cooling elements REA with intermittent by heat, made on the basis of melting heat accumulators with additional liquid heat sink. The basic computational relations for theoretical studies. Presents the dependence of the length of stable work of the REA element in ensuring its temperature conditions of the investigated system.

In this work the results of field tests of the prototype of thermoelectric system for thermal influence on the level of the middle third of the shoulder of the person, enabling the treatment and prevention of diseases of musculoskeletal system without medical intervention. Given the design of the device, experimental stand, and also a technique of field tests of the system. Presents the
characteristics of a prototype thermoelectric systems, recorded using the measuring bench.

The present paper is devoted to finding the maximum possible length of hydraulic passages extending in a natural line for the given parameters of useful effect coefficient and other performance parameters of polygonal section of the channel, using a set of computer programs.

Increasing the number of vehicles has led to urban congestion, many hours of traffic jams, obstruction of pedestrian traffic, increase the number of accidents, etc. Therefore, the importance of gaining the optimum network planning, improved traffic management, optimization of the system of public transport routes. The solution of such problems is impossible without mathematical modeling of traffic flows. An important task of modeling is to calculate the trip distribution. In this paper, we develop a program for calculating trip distribution using parallel computing technologies. The application of these technologies will improve the efficiency of simulation, increase accuracy and speed of the algorithm.

The resolving equations of finite element method for the problem of bending of three-layer flexible plate taking into account creep were obtained. These equations are valid for arbitrary laws of connection between creep strain and stress. In deriving the basic relations of FEM we took into account only the work of aggregate on shift. Comparison of the solutions in the FEM with the results
obtained by finite difference method with the work of bearing layers was made.

The work is devoted to experimental research of parameters of prismatic aggregate at static loading. The data of experimental researches allow to use them in the design of three-layer structures in space, aviation techniques, as well as in construction and machinery that is of interest for technical workers and designers.

Conducted research on the development of energy-saving modes of thermal sterilization of canned food "Tomatoes marinaded" using speed sterilization static cans. The proposed formula for expressing the speed modes of thermal sterilization of conserved products instatic state. Developed modes of sterilization of canned food "Tomatoes marinaded in banks by the volume of 0.5, 1.0, and 2,0 l

In work results of researches on improvement of technological process of production of tinned compote from pears with use of EMP microwave oven and high-temperature sterilization are presented.
On the basis of the conducted pilot researches and with use of mathematical planning the approximation equation for determination of reference temperature of a product in bank before sterilization (T, °C), depending on three factors is received: container volume (V, k), microwave heating capacities (Р, kW) and processing durations (t, c):
New modes of high-temperature sterilization of compote from pears in various container are developed and offered.

In this article methods of synthesis and reactionary ability of metalcomplexes of tellurium-containing amines, azometines, of a problem of competitive coordination with use of the principle of "soft" and "rigid" acids and the bases (R. Pearson).

Discussed the organization of clinical nutrition at the hospital. Give a general idea of biotechnological systems. Developed a method of therapeutic feeding in the hospital using biotechnical systems for medical purposes.

Role and place of the small business are shown in development of the economy of the country. They are offered heuristic methods of the estimation of the increase and optimization volume of production and rendered services in progress small enterprise in sloppy economic ambience.
