Introduction. The present invention generally relates to construction elements for erecting structures, and also to methods of erecting structures with the use of construction elements. Construction elements for erecting structures are conventionally flat elements, which are assembled at a site of construction for erecting a structure. Such flat constructions elements cannot be too wide because their transportation with the use of conventional transportation means is not possible. It is therefore necessary to use the construction elements with reduced width to allow their transportation, or to produce wide construction elements at the construction site. It is therefore believed that it would be advisable to improve existing construction elements and methods for erection of structures with their use. Result. The new technology of construction, based on the use of precast reinforced concrete large-sized spatial structures with variable geometry, allowing transportation without the special vehicles. After truck shipment and restore the geometry, structure is mounted to final position. As a result of the only one mounting stage, load bearing and (or) enclosure structure, permanent formwork of a monolithic slab floor are erected. The proposed technology is confirmed by the author’s priority (Patent № US 8,615,967 B1 / Dec. 31, 2013) Conclusions. Patent search report and the actual fact of the U.S. Patent allow us to draw a conclusion on feasibility and prospect of new technology.

The results of processing of experimental studies of physical and mechanical properties of the samples centrifuged and vibrated. Evaluation of heterogeneity of fresh concrete properties to determine the changes in water-cement ratio (W / C), the residual water content and density of the thickness of the sample centrifuged, and the change of the strength properties of the hardened betona.Analiz experimental data showed that there is a significant change in the average density of the concrete (up to 4 %), the total porosity of the layer in a slurry is increased by almost 18%, while the strength of the concrete is changed in thickness to 18-25%. Using the method of least squares, obtained the strength of concrete patterns of change in the thickness of the samples.

The phenomenon of buckling under the creep of concrete arches was investigated. Solution of the problem carried out by means of the finite element method. To analyze the stability we used Newton-Raphson method. It has been established that there is a long-term critical load, beyond which the growth of the deflection has not fading character. As the equation of the relationship between the creep deformation and strains we used viscoelastoplastic hereditary model of aging concrete. To determine the creep strain we used a linear approximation with respect to time. It was found that the long critical load for considered arch was in 1.44 times lower than the instant critical load.

Due to a significant increase in stress effects on humans at the present time, there is a need to develop methodologies to optimize its functional state. The aim of this study was to search EEG correlates to define the permissible limits of the reserve functional state. The study was used the author's P-adic model of the trajectory transitions psychophysiological States. The study was conducted on 20 male students of the specialty " physical culture Taganrog Institute named after A.P. Chehova sessions free breathing. Removal of biological information produced by the international system "10-20" monopolar scheme on 8 leads (Fp1, Fp2, N3, N4, P3, P4, O1, O2), on the basis of computer EEG system "Kompakt-Neuro" (developer - scientific-medical firm "Neurotech"). These studies showed that paroxysmal activity can act as an EEG correlate of the permissible limits of the reserve functional status, beyond which begin serious pathological processes.

An analysis of snowplows in urban environments. Determined that the efficiency of snow removal from roads, sidewalks areas affected humps (bumps), borders, etc. In line with this analysis of structures working bodies (dumps), used in Russia and abroad, as well as analysis of patents. In accordance with the foregoing, all decisions on the management of blade can be divided: extra lever systems; modernization of hydraulic drive; use microprocessors; the combination of these approaches. Obviously, the use of processor technology is justified for high-tech machines, as a consequence has disadvantages in price, qualification of operators and maintenance personnel. For the modernization of existing equipment, at the moment, it is advisable to use the combined system using the lever and hydraulic drive systems. It is necessary to take into account the energy-saving technologies.

For the introduction of sycamore Spanish to in vitro culture most effectively used as explants cotyledonary leaves derived from a three-week seedlings. It is found that the optimal medium for the induction of callus formation is the MS medium supplemented with 2 mg BAP + 0.02 mg of 2,4 D + 0.2 mg IAA. Embryogenesis in callus cells of sycamore with a fairly high frequency induced on MS medium supplemented with 1 mg BAP + NAA 0.1 mg.
