The necessity to elaborate the Principal Scheme of National Ecological Network (PSNEN) has been caused by new requirements of the national policy in the field of environmental protection. The main purpose of PSNEN elaboration is to develop methodological basis for the next planning cycle in order to develop the system of especially protected nature territories. Such planning is executed in accordance with requirements of National Legislation in the field of especially protected nature territories. Peculiar feature of the proposed methodology consists in the interrelated consideration of urban framework, on the one side, and ecological network, on the other one, as two basic components of the spatial Republican framework..

The paper contains the results of experimental research. The purpose of the research is to investigate operational character of «Galit Wastes - Clay-Salt Slimes» system under various schemes of its loading. Investigations have been carried out with the help of pilot plant which models fragment of a dike and a slime storage in 1:25 scale. It has been revealed that at the initial stage of clay-salt slime loading the whole load is transferred to water. Due to this excess thrust is brought about in the soil medium. Next stages of clay-salt slime loading depend on dissipation period of excess thrust. Filling of galit wastes on clay-salt slimes leads to their strengthening in 7 - 10 days. This process is accompanied by the formation of soil layer with partial crystallization.

The paper describes edge bending of narrow high strip with the help of bending-rolling method in the rolls which are rotating with different peripheral velocities. An equation is proposed with the purpose to determine dependence of reduction, which is necessary in order to ensure strip bending, on the value of contact friction. Theoretical calculation and experimental analysis of the obtained data have been carried out.

Results of the investigations permit to make a conclusion that while changing reduction value and coefficient of contact friction it is possible to obtain bending of a strip along its whole length with the required radius.

The paper reveals the problems concerning control of geometrical parameters of toral surfaces. The problems connected with the control of surfaces of higher order are under consideration in the paper. New and unique control methodology of geometrical parameters of nominally toral surfaces on the basis of 5, 7, 9 control points is proposed. The proposed methodology is characterized by its universal character, low calculating costs and high accuracy. The paper describes software which has been prepared on the basis of the proposed methodology and is applied for execution of calculation experiment.

A new neural network algorithm for synthesis of program motions of robotic manipulators is proposed in the paper. In contrast to the well-known algorithms a new one makes it possible to plot a collision-free trajectory in 3-dimensional configuration space. The algorithm is based on a neural network model of the harmonic function. The efficiency of the proposed approach is proved by the examples of its practical application in the field of industrial robot programming.

The paper considers the development of an algorithm with the purpose to solve the problem of analytical designing of optimum controller for linear-quadratic functional with the given limiting restrictions. This function is formed with the help of Krotov’s method. This methodology may be used in resource saving technologies while soaking metal in the furnace. The paper reveals new methods of optimization that do not have analogues.

Methodology of dynamic calculation of compressed air preparation system with two-adsorber air drier is described in the paper. Calculation results of dynamic characteristics of compressed air preparation system are given in the paper. The paper contains practical recommendations on the development and application of the air driers.

The paper considers the method of diagnostics of electronic injection system of petrol engine by duration of injector opening. Comparative analysis concerning measurement of injector opening duration in relative and absolute forms and also their mathematical interrelation are given in the paper.The influence of value of injector opening duration on one-hour fuel consumption has been studied in mathematical expression. The paper contains practical recommendations on diagnostics of electronic injection system of petrol engine with the usage of an injector opening duration index.

The paper considers complex approach to power technological modernization of asphalt concrete mix production. This modernization radically changes structure of asphalt concrete production.

The paper reveals peculiar features of thermal calculation of oil-gas burner for two-stage liquid fuel combustion. The dependences for determination of CO, H₂, C0₂ and carbon content in the products of oil gasification have been obtained.

The purpose of the present work is to justify the design of a low-head hydraulic turbine whose efficiency is by 10... 15 % higher than the efficiency of a water wheel.

Theoretical investigations in respect of counteraction to torque of an impeller blade of a hydraulic turbine when it enters and leaves water flow have been carried aut.

The model of the developed hydraulic turbine has been manufactured. The model will be tested in the hydraulic channel of the BNTU.

The paper reveals the methodology for justification of rational inventory scope. The concrete example of its calculation is given in the paper. The diagram of the inventory changes has been plotted which makes it possible to manage it efficiently.

The paper considers practical aspects in the field of creation, legal protection and commercialization of intellectual activity. Classification and description of the objects of intellectual property are given in the paper. The paper contains the analysis of types of safeguard documents and terms of validity of exclusive rights to copyrights and industrial property.

Modem conditions of economy require an application of new approaches to enterprise management. The analysis has shown insufficiency of existing methods of management in automative repair service. The paper contains the proposal to use economical methods which may be considered as non-conventional ones for domestic practice, namely: controlling, management by objects and strategy as a determining method which gives an opportunity to react flexibly on the market requirements.

The paper contains critical analysis of the category «property». This category is considered in the paper as a unity of economic content and juridical form.

The paper considers disadvantages in the organization of industrial process. Measures for achievement of its higher efficiency and competitiveness are proposed in the paper.
