The FGM concept appears promising in improving the mechanical performance and reducing production costs of fiber cement building components. However, it has not yet been broadly applied to fiber cement technology. In this study we analyze the functionally graded fiber cement concept and its potential for industrial ap…
The temperature dependencies of the polyacrylic acid (PAA) adsorption layers structure on the alumina surface were studied. The amount of polymer adsorbed and the thickness ofpolymer adsorption layers were determined in the 15-45°C temperature range. The obtained increase of PAA adsorption and the increase of thicknes…
The transition of two first-order facet-to-rough ridges into a single first-order rough-to-rough ridge theoretically predicted for free surfaces has been observed in a slowly migrating grain boundary (GB). The reversible faceting-roughening transition of the tilt GB in a Zn bicrystal has been studied in situ. Above T…
The planktic species of the traditional cyanobacterial genus Anabaena represent a special generic entity, different genetically as well as morphologically from the typical (benthic) part of the genus Anabaena, based on the type species Anabaena oscillarioides B ornet ex B ornet et F lahault . The group of planktic spe…

Abstract\nA European survey on the presence of banned azodyes in textiles, in particular textile clothing, produced all over the world was performed. The selection of fabrics was planned among coloured textile products, in order to cover as many different types of fibres and type of garments as possible. The whole pop…
Cu(58.1)Zr(35.9)Al(6) bulk metallic glass (BMG) rod samples were prepared by suction casting into a water-cooled copper mould. The amorphous structure was confirmed with X-ray diffraction. The T(g) and T(x) were 760K and 799K, respectively, from differential scanning calorimetry (DSC) results. Thin disc samples were c…
Rotor eddy-current loss appears significant in high-speed permanent magnet brushless DC(PM BLDC) motors.The effect of segmenting magnets on rotor loss was analyzed with finite element analysis.Only when the circumferential width of the magnet segment is smaller than the skin depth,the eddy-current loss in the magnets…
Liposomes encapsulating antibiotics have always shown an improved therapeutic index and reduced toxicity. Among the factors which affect the efficacy of liposomes loaded with antibacterial agents are the surface charge on liposomes and the interaction of the antibiotic with phospholipid vesicles. In this work, the inc…
A cyclic horizontal loading test was carried out using circular RC columns damaged by different degrees of rebar corrosion.In the experiment,the seismic behaviors of circular corroded RC columns under different degrees of axial loads,such as bearing capacity,stiffness,ductility and dissipated energy capacity were stud…
A correlation has been found between the critical temperature of Fe-based HT superconductors and the positions of the Fe atoms next to the doping element positions. This correlation allows for the prediction of Tc from crystal lattice constants and explains the fractional numbers of the optimum doping concentrations.…
The Rankine-Hugoniot relation for shock wave propagation describes the shock speed of a nonlinear wave. This paper investigates time-domain numerical methods that solve the nonlinear parabolic wave equation, or the Khokhlov-Zabolotskaya-Kuznetsov (KZK) equation, and the conditions they require to satisfy the Rankine-H…
This study investigated the friction and wear characteristics of two super-hard coatings on M2 steel. One was AlMgB14, produced by pulsed laser deposition (PLD), and the other was a nanocomposite of AlMgB14-TiB2, produced by physical vapor deposition (PVD). Tests were conducted under unidirectional and reciprocating s…
The wool fibre exhibits a typical core − shell structure consisting of an inner protein core, cortex, and surface shell, cuticle (see Fig. 1). The cuticle consists of several layers (see Fig. 2). The upper layer, epicuticle, contains lipoproteins. Lipoid part of lipoproteins is bound by the sulfoester bond with protei…
Previous literature has proven that both softening species of CaCO3(s) and Mg(OH)2(s) are capable of removing silica, but the mechanisms were not clearly described. Three different possible removal mechanisms were discussed here: (1) Adsorption by aged CaCO3(s) and Mg(OH)2(s) (2) Adsorption by amorphous (freshly preci…
Summary There are several reports about the antidiabetic, antispasmodic and antihypertensive properties of Teucrium podium L. (TP). The aim of this study is to investigate the inotropic and chronotropic effects of aqueous-ethanol extract from TP on guinea pig isolated heart. 24 Dunkin Hartley guinea pigs weighed 350-4…
The relationship between crystal rotation axis orientations and active slip systems was investigated in an aluminum tricrystal deformed under compression to a strain of 0.15. Schmid factors of slip systems were examined for three component crystals. After compression, slip bands near a triple junction were observed us…
Abstract This article introduces an educational tool for a switched reluctance motor (SRM) drive system. It is prepared for undergraduate and graduate level students. Classical PI and Genetic PI controllers are used in SRM drive system. The Genetic PI controller was applied to the speed loop, replacing the classical P…
The Co(II), Ni(II) and Cu(II) metal ions complexes of Bis(4-amino-5-mercapto-1,2,4-triazol-3-yl) alkanes (BATs) have been prepared and characterized by elemental analysis, conductivity measurements infrared, magnetic susceptibility, the electronic spectral data and thermal studies. Based on spectral and magnetic resul…
Different Si(111) surfaces covalently derivatised with alkyl monolayers terminated by redox-active centres, namely reversibly oxidisable ferrocene and tetrathiafulvalene (TTF), and electrochemically polymerisable pyrrole, have been prepared. Ferrocene and pyrrole were attached to the silicon surface using carbodiimide…
