In this article the authors propose a new approach to information and metrological support and assessment of technical condition of metal-cutting machines, based on a phasechronometric method. A phase-chronometric information measuring system for the UT16P machine was created. The authors carried out studies of operat…
Fabric surface appearance is one of the most important visible properties of fabrics determining their price and consumer satisfaction. This characteristic is routinely evaluated with reference to a set of visual standards in the textile industry. The visual evaluation is unreliable, time-consuming, inefficient, and,…
Since 1999, cancer has been the leading cause of death under the age of 85 years and the eradication of this disease has been the long soughtafter goal of scientists and physicians. Cancer is a disease in which abnormal cells divide uncontrollably. These abnormal cells have the ability to invade and destroy normal bod…
Electroluminescent (EL) metal-semiconductor-metal nanojunctions are prepared by electrodepositing nanocrystalline cadmium selenide ( nc -CdSe) within ∼250 nm gold (Au) nanogaps prepared by focused ion beam milling. The electrodeposition of nc -CdSe is carried out at two temperatures: 20 °C (“cold”) and 75 °C (“hot”),…
The effects of rare-earth doping and low-temperature sintering on electrical properties of ZnO varistors were investigated. The potential gradient (E1mA) of the ZnO varistors increased significantly to 2247.2 V/mm after doping 0.08 mol% of Y2O3and sintering at 800°C for 2 h. The notable decrease of the grain size with…
Nickel-based nanocomposite coatings were prepared from a Watts-type electrolyte containing reinforcement’s particles (silicon carbide and graphite) to deposit onto the steel St-37 substrate. The electrochemical plating of the coatings in absence and presence of surfactants and reinforcements particles was carried out…
This paper describes a custom developed yarn parameterization system to characterize yarn diameter, mass and hairiness. The system has been named YSQ (Yarn System Quality) and is based on capacitive and optical sensors generally used to infer information about yarn quality. The designed sensor system is fully describe…
MOTIVATION: Ions are essential component of the cell and frequently are found bound to various macromolecules, in particular to proteins. A binding of an ion to a protein greatly affects protein's biophysical characteristics and needs to be taken into account in any modeling approach. However, ion's bounded positions…
We present a theory of the spin Seebeck effect driven by subthermal non-local phonon heat transfer and spectral non-uniform temperature distribution. The theory explains the non-local behavior of the effect arising from the fact that phonons that store the energy (thermal) and the phonons that transfer it (subthermal)…
Lattice growth models where uncorrelated random deposition competes with some aggregation dynamics that generates correlations are studied with rates of the correlated component decreasing as a power law. These models have anomalous roughening, with anomalous exponents related to the normal exponents of the correlated…
The investigations of the reactive magnetron depositing of the stoichiometric coatings “metal-metalloid” were done. The dependences between sputtering parameters of a target and processes of plasmochemical formation on the surface of sample “metal-metalloid” and formations of coatings of the appropriate structure were…
In Indonesia, pesticide formulation mostly used is Emulsifiable Concentrate (EC). In order to get a suitable formulation in application, effective in use, stable in certain period of time and economically, stabilization of emulsion become an important thing. The stabilization is influenced specially by variety and opt…

Resistive switching with a self-rectifying feature is one of the most effective solutions to overcome the sneaking current issue in a crossbar structure. In this letter, we have successfully demonstrated a prototype device with inherent rectifying property with a-Si/WO3bilayer structure. After a forming process, the d…

research investigates nanoscale droplet deposition phenomena towards developing nanomanufacturing processes. The deposition and spreading behavior of water nanodroplet on SiO2 and Si3N4 substrates is studied using molecular dynamics simulation. The effect of temperature variations on the dynamic contact angle during t…
A 18-constant additive scheme for calculating the physicochemical properties of alkylsilanes is obtained, based on the transferability of subgraphs in molecular graphs of the homologic SiC n H2n + 4 series of alkylsilanes. The model considers multiple nonvalence interactions through no more than one atom and pair nonv…
It is shown by magnetic field dependent ac susceptibility, magnetic force microscopy, and ferromagnetic resonance that exposure of C60 to fluorine at 160°C produces a stable ferromagnetic material with a Curie temperature well above room temperature. The exposure to fluorine is accomplished by decomposing a fluorine-r…
Recently we wrote a paper on the theory of the quantum spin Hall effect(QSHE) in two dimensional(2D) topological insulators(TIs)1 which have been considered as do not add much new insight to the exhaustively studied topic of TI within a single-electron picture by the referees. In this paper we review the papers on the…
Three dimensional topological insulator crystals consist of an insulating bulk enclosed by metallic surfaces, and detailed theoretical predictions about the surface state band topology and spin texture are available. While several topological insulator materials are currently known, the existence and topology of these…
