The question of the self-consistency of spin wave theory as applied to different spin arrangements in magnetically ordered crystals has been reinvestigated. A set of equations, involving the probabilities of finding a given number of spin deviations at a given site first proposed by Van Kranendonk and Van Vleck (1958)…
In recent years, there has been substantial interest in the development of microelectro-mechanical systems (MEMS) and even nanoelectro-mechanical systems (NEMS) for use in a wide variety of applications both as experimental tools (refs) and in a continuing effort to decrease the size and cost and increase the efficien…
Single crystals of pure and transition metal doped CaFe2−xTxAs2 (T = Co and Ni) have been grown by flux method using molten Sn as solvent. The magnetic and superconducting properties of the grown crystals were studied by measuring the electrical resistivity, magnetic susceptibility and neutron diffraction measurements…
Recently, sulfoxides have also found applications as chiral Lewis bases inducing high enantioselectivities in the allylation of aldehydes and hydrazones with allyl trichlorosilane.26 However, stoichiometric use of the respective chiral sulfoxide is necessary to obtain good conversions and high enantiomeric excesses (S…
The phonon dynamics of orthorhombic multiferroic perovskite RMnO3 (R = Er, Tm) using a shell model with pairwise interionic interaction potential has been investigated. The present work includes the computation of the structural parameters, phonon frequencies and the specific heat curves. The symmetry vectors obtained…
The dependences of phase transition temperature of ferroelectric granule on it's sizes, form and contact type with environment have been determinated on the base of phenomenological Ginsburg-Landau-Devonshire theory. According to the rules of effective medium the dependences on temperature and size of granules have be…

The vertical displacement of the surface graphene layer on graphite is performed with the tip of the Scanning Tunneling Microscope (STM) during imaging, mediated by the tipsample interaction. This surface decoupling spanning several tens of nm laterally is manifested in the observation of a switch between the triangul…
Propylenoxid ist ein wichtiger chemischer Rohstoff für die Herstellung von Polyurethanen und Polyolen. Mit einer Weltjahresproduktion von 7,5 Mio. t gehört es zu den Basischemikalien, weshalb seiner ressourcenschonenden Produktion eine große Bedeutung zukommt. Die bislang industriell etablierten Verfahren wie das Chlo…
The describes the experimental installation for studying long-term strength of unidirectional polymer composites materialov. Used as a model sample mikroplastics is loaded using chart changes in forces and displacements are recorded hydraulic cylinders to its destruction, the info light-sensitive tape recording. Exper…
The methodology of the optimization of the interlock blade-disk of the type “fir tree” is examined within the bounds of this paper. The methodology is based on the method of the complex experiment. Agodjino criterion of the stress-state rigidity and the plasto-elastic deformation energy of the material are used as the…
The analysis of influence free electrons on shaping solitons is resulted. Influence free electrons on different frequencies and non-linearity in conditions of a dispersion of the third order are examined
The integral criterion forming procedure of quality evaluation of constructive solutions concerning motor-cars is developed.

This paper explains the research results of leakage current, hydrophobicity and flashover voltage comparison on ceramics and epoxy resin 20 kV outdoor insulator in a chamber at tropical climate conditions. The waveform of leakage current (LC) was measured using a digital oscilloscope. The digital data was transferred…
A series of polycrystalline compounds with a nominal composition of Y(Ba1‐xCax)2Cu3O7−δ (0⩽x⩽0.05) had been synthesized using solid state reaction method. Crystal structure of those samples was characterized by Rietveld refinement on the x‐ray powder diffraction data. It was found that the structural parameters were n…
The article is develops the method test and definitions of limit fracture strain of bend with tension. This type of test is determines the strain of destruction in the region near the plane strain, without provoking the development of cracks due to manufacturing techniques. This method is uses for improving the accura…
This paper deals with further development of Wiener-Hopf-Fock method for ob- taining the characteristic equation which follows from the solution of the boundary value problem of electromagnetic waves difiraction on the strip-slotted structures. The strip or an inflnite grat- ing is chosen in return for strip-slotted s…
The effect of solid additives of iron(III) oxides was investigated in the synthesis of diphenyl ethers by nitroclorinebenzene with phenoxide anion interaction in the environment of N, Ndimethylformamide. The influence genesis of hematite by interaction speed of primary stage was considered. The possible character of t…
