Dynamic domain-structure behavior during rotational magnetization reversal of a single-crystal Fe-3% Si disk with the [001] crystallographic axis deviated slightly (at an angle β = 1.5°) from the specimen plane have been investigated on the surface of the specimen. New regularities of the changes in the closure domain…
Changes in the mineralogical composition of the clay fraction (<0.001 mm) sampled from soils of the model lysimetric experiment of Moscow State University have been studied. The mineralogical composition of clay is represented by the paragenetic association of minerals typical of noncalcareous mantle loams in the cent…
Abstract Bis(n-butylammonium) pentachloroantimonate(III) was obtained in a reaction of n-butylammonium chloride and antimony trichloride (molar ratio 2 : 1; cation : Sb) in acidic aqueous solution. To obtain further information about the mechanism of the earlier reported phase transitions at 229 and 315 K the structur…
l'occasion du 150e anniversaire de la parution de l'ouvrage de Henry Darcy intitulé Les fontaines publiques de la ville de Dijon et dans lequel il énonce les principes de la loi qui porte son nom, le présent article met en perspective le rôle essentiel de la découverte de Henry Darcy dans les études d'écoulement des f…
The role of semiconductor packaging has evolved from space transformation and environmental protection, to becoming an important enabler for silicon and system performance. This paper examines some of the advances in flip-chip packaging as an enabler of power delivery and power removal using a microprocessor as an exa…
By solvent crystallization using diethyl ether as the solvent on sterol mixture, brassicasterol and stigmasterol that contains a side chain with double bond were separated from campesterol and β‐sitosterol with a saturated side chain. The total campesterol and β‐sitosterol content in the liquid phase was more than 97%…
The thermal conductivity of solid parahydrogen is investigated using the stationary method with a plane sample in the temperature range 1.5–6.0 K in order to reveal a Poiseuille flow in solid hydrogen. It is established that the thermal conductivity at temperatures below the low-temperature maximum decreases very rapi…
Adherent and low-stress a-C:H films were deposited on Ti6Al4V and stainless steel substrates using PECVD and IBAD techniques. An amorphous silicon interlayer was applied to improve the adhesion of the a-C:H films on the metal substrates. The XPS technique was employed to analyze the chemical bondings within the interf…
Purpose The aim of presented investigation was to test developed testing device Griff tester, created for the objective evaluation of textile hand and to compare the obtained data with sensory evaluation results of textiles, subjected to different final treatments. Design/methodology/approach The effect of two finishi…
Abstract This document shows that new electrically active defects can develop in the homoepitaxial layer grown on Ib diamond substrates, related to the increase of the dislocation density. Deep centres, which are able to compensate the boron acceptors, specially when the growth process allows boron incorporation below…

The heat capacities of cattle and poultry collagen samples were measured by adiabatic calorimetry in the range 80–330 K. The temperatures of physical transitions in these samples were determined. Endothermic relaxation transitions (γ 1 , γ 2 , and β) were observed in the heat capacity curves of the studied collagen sa…
Purpose Aims to analyse the stress distribution in a circular flexible sheet. Part I provides a theoretical approach to the analysis of the bagging deformation in textile fabrics. Design/methodology/approach The investigation includes analysing the stress distribution in a circular flexible sheet clamped around its ci…
Single carbon nanotubes are investigated with respect to possible antenna applications. On the basis of an electromagnetic analysis and under consideration of the quantum transport effects a transmission line model for the electromagnetic wave propagation along single carbon nanotubes is investigated. The scattering o…
The MS/MS fragmentation of the alkali metal complexes of monensin A are studied. The increase in alkali metal ionic radii decreases the ability of the Grob-Wharton fragmentation mechanism to occur and reduces the overall degree of fragmentation. Conversely, the electronegativity of the metal cation is related to the n…
Abstract A new method for determining the cation exchange capacity (CEC) of clays is proposed. The method is based on X-ray fluorescence analysis of natural and Ba-exchanged clays following the analytical procedure suggested by Franzini et al. (1975). This procedure, which utilizes powder pellets and is based on a ful…
The properties of ferroelectric ceramics based on barium strontium titanate and doped by admixtures with low permittivity and dielectric loss tangent are studied experimentally. These ceramics are viewed as a promising material for microwave devices applied in the acceleration technology. Ceramic samples the I-V chara…
The piezoelectric properties of a Pb[(Mg 1/3 Nb 2/3 ) 0.68 ]Ti 0.32 O 3 [PMNT(68/32)] binary-system single crystal poled along the [001] direction in the rhombohedral phase were investigated under various pressures up to 400 MPa at 25 °C. The electromechanical coupling coefficient k 33 in the k 33 mode decreased sligh…
The stability and lyophilization of core-shell PCL-PEG-PCL micelles were investigated by fluorescence spectra, DLS, DSC, WAXD, and FT-IR. The prepared micelles were not stable when they were stored in aqueous dispersion under different condition. Their size increased in the first 20 days and decreased gradually when t…
Among a series of power ramp tests on 25 Zr-lined segment rods of burnup ranging from 43 to 61 GWd/t, five segment rods failed during the power ramp tests. One segment rod irradiated for 3 cycles (43 GWd/t) failed with a pinhole due to PCI/SCC. The rest of higher burnups failed with an axial crack on the outer surface…
