Computer Modellig оf the Local Distortions of Geometric Shape of One-Layer Lattice Domes
Abstract
Solution of the problem of modeling the local distortions of geometric shape of one-layer domes and its program implementation are presented in the paper. Modeling is based on selection of nodes on the computer screen and assigning the values of initial deviations of selected nodes from the ideal surface along the normal to this surface. The graphical user interface of the program includes the necessary set of instruments and the color palette of visualization for the pattern of distortion.

Diagnostics of Chemical Activity of Antifreeze
Abstract
The method thermoactivation current spectroscopy were spent an estimation of chemical activity of antifreezes (degree of aggression of a cooling liquid as solvent in relation to rubber). It is established that chemical activity of antifreeze is connected both with temperature of a cooling liquid, and with a hydrogen indicator of environment.

Multipropellant Mixed Biofuels for Diesel Engines
Abstract
The characteristic features of using multi-propellant mixed biofuels with rapeseed oil in diesel engines have been considered. The results of experimental research of a type D-245.12S vehicle diesel engine running on diesel fuel, rapeseed oil, rapeseed oil methyl ester and gasoline multi-propellant mixtures have been shown. The dependence of fuel efficiency and exhaust emission characteristics on mixed biofuel components has been shown.

Trajectory Accident Prevention in Problem of Fly-Around of Static Circular Forbidden Zone
Abstract
Trajectory accident prevention in a problem of fly-around of static circular zone forbidden for planar motion of a dynamic controlled system is considered. Subproblems which are necessary to solve for trajectory accident prevention are developed. Generation of generalized forbidden zone model is realized, description of boundary zone of safe turn-away from forbidden zone is obtained, range limits of dangerous motion directions of the dynamic controlled system are developed.

Basic Aspects of Mathematical Modeling of Electric Energy Consumption on Mainline Pipeline
Abstract
An actual task planning of electric energy consumption on throughput for trunk oil pipeline are considered in this article. Main results of the statistical analysis of characteristics of simulated object, principles and methods of construction of mathematical models were shown. For built models are obtained to assess their adequacy and results verification. The problem is solved by using real data observation one linear plot of trunk oil pipeline.

Natural Leaching of Uranium and the Mechanism of Destruction of the Ore Bodies and Rocks
Abstract
Leaching of the metal begins after the filing of a working solution to the array and ends in a short time. The process of leaching in the microcracks is long, and the process of leaching in the mikropores is longer.
An important parameters of leaching of uranium are: the area of actively surface cultivating of minerals, which means а destruction of ores and rocks.
