Thomson spatial heat sources power is determined. It is shown that the heating spatial source helps reduce the total flow quantity entering the plate, and expand heat penetration. The volume cooling source in the tool material plate, conversely, removes an additional quantity of heat from the contact zone increasing t…
A new method of the threshold sharing of any format file on n parts in such a way that it would be necessary to collect at least k(<n) parts for its correct recovery is offered. The proposed method can be used for decentralized filing, file transfer through the multichannel networks, and for unauthorized access protec…
The social and philosophical analysis of the development of the law and legal socialization idea in the history of philosophical thought is given. Besides, some negative features of the legal socialization in the contemporary Russian society are revealed.
The industrial management practice of the service industries implies that the ‘goods’ category not only specifies the tangible form transformations, but sets the basic trends of the effective operation of the sphere at large. The transformation of the ‘goods — service’ tangible component should be considered within th…
The possibilities of using the system and synergistic approaches to research society are analyzed. The concepts and principles of the system and synergetic methodological conceptions, and social models by T. Parsons, N. Luhmann, A. Davydov are considered. Society is described as a certain type of evolutionary system.…
Incorporation of functional water-soluble technological lubricants (FWTL) of zinc nanopowder into fractal clusters improves their greasy properties, and increases the stamping efficiency and iron plate draw-forming under the transport body parts fabrication.

Curing reaction of bisphenol-A based benzoxazine with cyanate ester resin and the properties of the cured thermosetting resin were investigated. The cure behavior of benzoxazine with cyanate ester resin was monitored by model reaction using nuclear magnetic resonance (NMR). As a result of the model reaction, the ring…
We present a study of the electronic and magnetic properties of the multiple-decker sandwich nanowires ($CP-M$) composed of cyclopentadienyl (CP) rings and 3d transition metal atoms (M=Ti to Ni) using first-principles techniques. We demonstrate using Density Functional Theory that structural relaxation play an importa…
We employed an easy and direct method to measure the thermal conductivity of epoxy in the liquid (nanofluid) and solid (nanocomposite) states using both rodlike and platelet-like carbon-based nanostructures. Comparing the experimental results with the theoretical model, an anomalous enhancement was obtained with multi…
Mixing 60-70% lead zirconate titanate with 40-30% lead iron tantalate produces a single-phase, low-loss, room-temperature multiferroic with magnetoelectric coupling: (PbZr0.53Ti0.47O3) (1-x)- (PbFe0.5Ta0.5O3)x. The present study combines x-ray scattering, magnetic and polarization hysteresis in both phases, plus a sec…
To gain important information on fate, mobility, and bioavailability of silver nanoparticles (AgNP) in aquatic systems, the influence of pH, ionic strength, and humic substances on the stability of carbonate-coated AgNP (average diameter 29 nm) was systematically investigated in 10 mM carbonate and 10 mM MOPS buffer,…
In this study, we present a biological method for synthesis of silver nanoparticles (AgNPs) using Streptomyces sp. ERI-3 cell-filtrate. AgNO3 solution (1 mM) was added to the cell-free culture supernatant and the mixture was incubated at 28 °C for 48 h in the dark in an orbital shaker. The AgNPs were characterized usi…
The Fe-based superconductors (FBS) are an important new class of superconducting materials. As with any new superconductor with a high transition temperature and upper critical field, there is a need to establish what their applications potential might be. Applications require high critical current densities, so the u…
This work theoretically and experimentally reports the evanescent connections between propagating bands in periodic acoustic materials. The complex band structures obtained by solving for the $k(ω)$ problem reveal a complete interpretation of the propagation properties of these systems. The prediction of evanescent mo…
Selected problems of electrochemical synthesis, characterization and applications of titanium dioxide are reviewed. These issues have attracted considerable attention from addressing purely academic questions up to promising applications in devices for energy storage and energy conversion.
In molecular dynamics (MD) simulations, interactions between water molecules and graphitic surfaces are often modeled as a simple Lennard-Jones potential between oxygen and carbon atoms. A possible method for tuning this parameter consists of simulating a water nanodroplet on a flat graphitic surface, measuring the eq…
The mobility and deposition of capped silver (Ag) nanoparticles (NPs) on silica surfaces were characterized over a wide range of pH and ionic strength (IS) conditions, including seawater and freshwater. Two common organic capping agents (citrate and PVP) were evaluated. Both the capped Ag NPs and the silica surfaces w…
A viscoelastic model of fuzz growth is presented. The model describes the main features of tungsten fuzz observed in experiments. It gives estimates of fuzz growth rate and temperature range close to experimental ones.
Neutral liposomes (NLP) exhibit preferential localization in solid tumors based on the enhanced permeation and retention (EPR) effect. Cationic liposomes (CLP) have a propensity for localizing in newly formed tumor vessels and they have a potentially enhanced antitumor effect. However, an increased amount of cationic…
