The solid solution of  LiMn1/3Cr1/3Fe1/3O2 with the structure of α-NaFeO2  isostructural with the widely used LiCoO2  has been synthesized and investigated as a cathode material. Rated voltage of LiMn1/3Cr1/3Fe1/3O2  relative to the lithium is 4 V.  The possibility of charging − discharging the material to a specific capacity of 220-250 mAh/g at currents of C/15-C/50 without phase transformations has been experimentally demonstrated.

At the present time in most countries of the world are being actively developed and introduced intelligent technologies necessary for creation of reliable and effective intellectual energy systems. Intellectualization of distributive electrical grids will move energy system to a new level of automation. Evenly distributed electrical grid of hexagonal type was offered. The principle of creation a grids was described, a typical scheme of universal electrical load unit was proposed. The key advantages of the hexagonal network was reviewed. The estimation of the reduction of the level of losses during electricity transportation was made. The increase of the level of reliability, the factors affecting the probability of faultless work were determined. Evenly distributed grids of hexagonal type will build energy system based on Smart Grid and solve existing problems: lower quality of electricity, the shortcomings of the power reserves, high density of electrical loads and high energy losses. Project implementation should be carried out in stages: from pilot project to implementation in big cities.
Work is executed with financial support of Ministry of education and science of the Russian Federation (state contract №14.516.11.0104 from 14.10.2013).

In this paper the technology of repair of ground water retaining structures soil mixture improved quality with and without soil mixture install.Use soil mixture , improved sharps and ensure the return of ashes (repaired ) slopes and ridge structures of high strength (up to 13-15 MPa) and water resistance , thus increasing the effectiveness and quality of the repair work and increased resistance to the elements of the structures induced defect . The presence of the bran soil mixture not only enhances the strength of 30-40% , but also gives a significant increase in water and frost (20-30 %), which prevent or substantially reduce the infiltration of water through the filtration body water retaining structures , since high strength and frost soil-concrete being laid on a slope ( in the recovery slope failure ) and groove (at soil dumping and capacity to or in excess of the design marks ) will reliably protect the body of the dams ( dams ) of the drawdown , erosion , buckling , suffusion , and other deformities.

This article describes the model of the pseudorandom sequences (PRS) generator developed in OrCAD program suite.The described model is applicable for radio systems modules circuits simulation that are using in the operation a PRS. The PRS generator implementation in OrCAD make possible to change PRS parametres immediately in the program, without using other software. A model specificity is that it is parametrised. Parametrization facilitates model control and that is reduce to a minimum necessary manipulations for changing of PRS type. The model is constructed on the basis of circuitry implementation of the linear feedback shift register (LFSR). For adjustment of model it is enough to instal code words setting starting state a LFSR, parametres of a signal of a clock source and to specify register tap output. As an example, used a 16-bit LFSR to create maximum length PRS, tap sequence {0, 5, 9, 13}. Emulation results are presented.

Intracellular microinjection - a method of direct introduction of cellular organelles and solutions of substances into living cells. The technique of microinjection into nerve cells by puncturing their processes - axons , which are often surrounded by a dense glial sheath, are described. To puncture the sheath a special injector transmitting microvibrations of ultrasonic frequency on the injection capillary was designed. The results of using the proposed microinjection technique for introducing fluorescent marker in large axons of model object - crayfish ventral nerve cord, to visualize the morphology of axons, were shown.

The article discusses the stability of the chernozem biological properties in the combined pollution of lead and an alternating magnetic field. Soil parameters such as the activity of catalase and dehydrogenase, soil biomass, soil phytotoxicity are considered. The main contribution to the change in the biological properties of the soil in the combined pollution by lead and an alternating magnetic field makes lead pollution. The contamination alternating magnetic field with a high level of induction (3000 mkTl) over only reduces the amount of lead pollution of soil biomass, but increases the activity of soil enzymes. At a lower level of induction (300-1500 mkTl) with combined pollution increases the activity of enzymes and biomass is virtually identical to the activity only if contaminated with lead. Phytotoxicity indicators of soil pollution with lead and an alternating magnetic field induction of 300 mkTl did not differ from those of soil contamination only lead, but with an increase in the level of induction to the 1500-3000 mkTl phytotoxicity indicators declined in comparison with the lead pollution at 18-27%.

The authors suggest two approaches to constructing hypotheses about the interactions of proteins on the basis of the results of tracking the changes in their levels during the studied biological process. The first approach is based on the use of machine mining of biological texts, which are freely available on the Internet. The second is related to the execution of database queries on binary protein-protein interactions . To specify the experimental context in obtained protein networks, filtering of the protein entities on the basis of needed ontology from database Gene Ontology was used.

In this article showed the data about the system of voluntary certification of works on labour protection. The certification process involves the confirmation of compliance of the enterprise (organization) on security and labour protection, to the established state normative requirements. Implementation of the procedure of certification of the state of labour protection works is the main condition for the improvement of the OSH management system in the organization.
