In this article we investigate the change in wetting behavior of inkjet printed materials on either hydrophilic or hydrophobic plasma treated patterns, to determine the minimum obtainable track width using selective patterned μPlasma printing. For Hexamethyl-Disiloxane (HMDSO)/N2 plasma, a decrease in surface energy o…
Door een verslechterde prijsvorming van kleine peren neemt het belang van dunning bij Conference toe. Bovendien wordt met het duurder worden van arbeid en met een toenemend areaal de noodzaak groter om via chemische dunning de hoeveelheid handdunwerk zoveel mogelijk te beperken. Vanaf 2007 wordt daarom door PPO onderz…
A method of studying the nature of the stress-strain condition of shell structures is proposed in the paper. The proposed method takes into account the interaction (in a physical model) in between ground environment and thin shell with filler. The method is one of the steps in creating a more accurate mathematical mod…

Multifractal parametrization used to assess the quantitative description of the heterogeneity of the structures, which in contrast to traditional methods of describing structure provides great opportunity to identify the complex structure of steel, as well as descriptions of materials with undifferent or hard differen…
In this given work we researched the modern methods of increasing the light output power of LEDs based on quaternary heterostructures AlGaInP. The main investigations include replacing the main substrate, varying the concentration of the elements included in the active region, the growth of distributed Bragg reflector…
The magnetic, magnetoelectric, and magnetoelastic properties of RFe3(BO3)4 ferroborates are studied. The measurement of the field dependences of the magnetoelectric polarization along the a axis in holmium ferroborate and in the mixed composition Ho0.5 Sm 0.5 Fe 3 (BO 3 ) 4 revealed the following depen� dences for eas…
Вакуумные электропечи получили широкое распространение в связи с возникновением таких отраслей промышленности, как самолетостроение, атомная, ракетная и др. Вакуумная плавка металлов и сплавов в печах позволяет значительно снизить содержание газов и количество неметаллических включений, обеспечить высокую однородность…
The properties of metal oxide nanocrystals in energy-related devices are strongly dependent on the presence and chem. nature of ligands at their surface, and the architectures they assume in electroactive layers. The article presents a comprehensive strategy to control these aspects of the electrode's design. In parti…
Fouling continues to be an important issue in dairy processing and has a significant financial impact for dairy processors. From a dairy processor's point of view, we consider fouling to be a holistic combination of microbial fouling (biofouling or biofilm formation) and non-microbial fouling (protein, mineral, and fa…
Kondratyuk V.A., Petrov V.N., Voskoboynikov I.V. RESEARCHAND TECHNOLOGY DEVELOPMENT OF COMPOSITE RAILWAY SLEEPERS. Research and development of technology and equipment for the production of composite railway broad gauge sleepers. Components molded sleepers made from wood waste from old car and tractor tyres. Carried o…
The results of modeling the process of pressing a flat slabs of bark and waste thermoplastics. To quantify the distribution of the thickness of plates obtained with factors such as temperature, degree of curing thermoplastic shear and normal stresses at the interface and thermal stresses.
Nanostructured ZnO powders with particles of tubular form were synthesized by a precursor method. Anarrow symmetrical line with a g factor of 2.002 was detected in the ESR spectra of the materials. On the basisof analysis of the dependence of the line intensities on the heat treatment conditions it was concluded that…
The mathematical models of solid-phase postpolymerization device and combined drying and monomers removal apparatus are developed. These models usage allows predicting therational regime and process parameters as well as constructional parameters of an equipment. The results of numerical experiment are presented. The…
Directional cracking in Ti,C:sapphire crystals grown along [1120] by Vertical Bridgman method often occurs in the cutting and processing process. In this work, we discuss the characteristic and mechanism of directional cracking of Ti,C:sapphire, and find that directional cracking originates from (1100) lattice plane a…
VI)-ионы – мелафен (пирафен) получены качественные данные о взаимодействии между компонентами.Interaction of melamine and 2,4,6-triaminopyrimidine with molybdate(VI)-ions in water solution has been investigated by pH titration and mathematical modeling of equilibria (CPESSP program). It has been established that tetra…
account of the dipole-dipole interaction. Results are presented for CsI, CsOH, HI, and Cs 2 MoO 4 , which are the main components of the fission products in transport of radioactive iodine and cesium in the first loop of a reactor. It is shown that this contribution decreases the diffusion coefficient of the dipole mo…
The purpose of this study was to improve the reduction of timber drying time by using drying air with low-relative humidity. The low-relative humidity of the drying air studied was in the range of to 25 - 35 %, and the condition of drying air was fi xed at a temperature of 40˚C and velocity of 1.0 m/s. The physical qu…
In this study, the origin of amounts of localized strain in basal textured Magnesium alloy sheets was investigated. First, grid patterns were drawn on a top surface of sample by Focus Ion Beam system. And then, a distribution of crystal orientation from same area was observed by SEM/EBSD. From these methods, the relat…
Two micromechanics models for three-dimensional (3-D) open- cell foams are presented. In the first model, an energy method based on Castigliano's second theorem is utilized. The analysis is performed on a tetrakaidecahedral unit cell, which is subjected to compression on its two op- posite square faces. The thirty-six…
