Problems concerning energy saving become more urgent in the connection with permanent increasing of electricity price and enactment of the law regarding energy efficiency and energy saving. Regulated electric drive has been using widely for energy saving within pumping plant. Appropriate equations were carried out for adequate regulation of technology process of water travel and energy supplying. The analysis of criterion function for optimization and efficiency factor for specific elements as well as whole system makes it possible to find out the optimal system parameters and define energy saving work conditions
There were cited the results of use of lignificated grafts of clonal stocks under production of planting material of sweet cherry. There was set the availability of new elite stocks ELITA-1, ELITA-2 and ELITA-9 along with standard clonal stocks VSL-2 to propagation of lignificated grafts. It is recommended the intensive technology of sweet cherry grafts growing on the basis of it
In the article, the dynamic characteristics of frictiondual-tillage of a wood soil-cultivating mill as object of automatic control are presented
In the article, the questions of substantiation of a way of the maintenance of soil in gardens on hillsides, the constructive scheme of the rotational garden mower providing cutting of vegetation at different levels are considered
The rational method of efficient control of agroecosys-tem in arid areas of Northern Caucasus, based on ex-pansion of perennial grass sowing is offered. The intro-duction in phytocoenosis structure of multicomponent grass mixtures with meadow and leguminous grasses provides a high recoupment of antropogenous expenses
Description of hydro kinematic scheme of forest manipulator with additional damper connection is given in the article. Optimal damper parameters for manipulator dynamic loading decrease are defined on the basis of operation mathematical model solution

The article is devoted to the numerical solution of boundary value problem of the binaryelectrolyte model of transport in membrane systems in the approximation of Ohm's law. Different numerical methods are offered. The main regularities of transfer are established
The models, algorithms, methods of design automation of specialized devices of permutations generation within the variable width string are presented in this article. The methodology of design of such devices, which provides high-quality project and maximal automation of design process at system level and register-transfer level (RTL) is offered. At the end of the article, the efficiency of the offered solutions is estimated
In this article, a model of preons electric currents caused by the motion of preons in the electron shells and nuclear shells is proposed. It is assumed that preons currents may contribute to the conductivity of the material. A closed model of electrodynamics, which describes the diffusion of the vector potential due to the contribution to the conductivity of preons currents, is formulated. An analogy of hydrodynamics and electrodynamics of continuous media with preons currents is considered. A model of the wireless transmission of electricity is proposed
