The technique of the geometrical analysis and the analysis of force loading of combined drills with the replaceable multiface plates is offered in this work. This technique is allowing to determine geometrical parameters and specific force loadings in each point of a plate’s cutting edge taking into account its orientation in the drill case. Application of this technique allowed to establish the reasons of the drill’s low durability. The offered technique allows to design drills from the minimum unbalanced radial component of cutting force which increases its working capacity and the processed holes quality. New designs of combined drills both with two, and with three replaceable multiface plates are offered in this work. The durability of this new drills is increased by the plates mutual turn for the minimization of an unbalanced radial component of cutting force

"This review covers various methods of synthesis LaMnO3 ferroics. The general analysis of the solid-phase synthesis reactions methods and wet methods (sol-gel, sorption, co-precipitation) are carred out. The original results of LaMnO3 syntheses from various precursors by means of the in situ method are showned. The advantages and disadvantages of different methods of synthesis are determined. The analysis of synthesis LaMnO3 ferroics published data is shown:
- the structure formation of LaMnO3 in perovskite-type phases occurs at different temperatures, depending on precursors states;
- LaMnO3 perovskite phases differ in symmetry and unit cells parameters at room temperature, depending on the preparation conditions;
- the highest synthesis temperature of LaMnO3 are typical for solid phase reactions method (950-1050 ° C), the lowest - for wet synthesis methods (500-700 ° C);
 - the synthesis conditions effect the stoichiometry of LaMnO3 for oxygen content.
Our studies of structure formation processes of LaMnO3 by in situ method are allowed to define the role of precursors states at synthesis of solid phase reactions methods, adsorption, co-precipitation and sol-gel mixtures.
It is determined that in samples prepared by wet chemical methods, the formation processes of  LaMnO3 perovskite phases occur at lower temperatures than by solid phase reaction (sol-gel precursor - 500 <T <600 ° C; precursors obtained by coprecipitation and sorption methods - at 600 <T <700 ° C and 700 <T <800 ° C, respectively).

This article is devoted to the analytical determination of deflections of beams with corrugated web. The reduced shear modulus which must be considered when determining the components deflection from of the shear strain in the beam with corrugated web is defined. Applying the energy method in the form of the Ritz, the problem of determining deflections with considering of bending strain and shear strain is solved. This article, as an example, is considered simply supported beam on both sides of constant and variable cross-section and are given to the final formulas according with three kinds of loading.

Consensus problem involves a system of processes, some of which may be faulty. A fundamental problem of fault-tolerant distributed computing is for the reliable processes to reach a agreement on a same decision. One approach to achieving such agreement is for processes to vote and agree on the majority value. In the absence of faults, this works fine, but the vote even one faulty process can swing the outcome. In this paper we present some result of analysis of a mixed-failure model, where t processes may fail, b out of which is the Byzantine failures and remaining c is crash processes. In a asynchronous model of computation for several distributed problems it turns out that a collection of N processes can tolerate c crash failures if 2c < N, while robustness against b Byzantine failures requires 3b < N. Our algorithm rely on a weak definition of the Byzantine failures which disallows them act as a dead or a crash processes and can tolerate the 2(N – 2c)/3 failures.
