Relationships of cause and effect which are the cornerstone of the phenomenon of observability of area of hydrophysical indignations from an underwater moving object, including its exit to a sea surface when lighting the area in the thickness of water by a laser beam and radiation of the sea surface over an object with a radar station signal are described in the article. In the stationary marine environment the laser beam creates a backscattering signal of a fixed level. In the area of hydrodynamic indignations from an underwater moving object the signal of a backscattering of variable brightness to the relevant structure and level of indignations is seen. The similar phenomenon of a backscattering of the electromagnetic radiation of radar station that creates glare effects on the screen of radar station in a zone of an exit of hydrodynamic indignations is observed on a water surface. It is shown that these phenomenons have similar nature caused by the change of dimensional orientation of dipoles of molecules and liquid crystals clusters of water in the field of the hydrodynamic indignations accompanying the moving of an underwater object. Establishing of this characteristic, in case of its confirmation by test data, meets the requirements of qualification of opening.

The paper considers the question of determining the thickness of the beater blade when interacting with the rods of a top-removing conveyor and the conclusion about the expediency of applying a new working organ for separating potato tubers from the tops.

Authors of this article note that one of the widely used in practice methods of strength calculation of structures is the finite element method (FEM). FEM is a procedure of approximate solution of differential equations. It was originally designed for solving problems related to the calculation of strength of structures, that is, to calculate forces, stresses and strains in solids.

This paper describes pedestrian suspension bridges of the Lipetsk region. The author concludes that these bridges are unique structures and could be built in many remote places.

The technique of definition eccentricity orbits only by measurement of angular position of a planet is offered.

New design of trussed beams of the new cutting. The calculations of all its elements and determined the cost of steel. Built appropriate tables and graphs for various variants of the design.
