In this study, knitted fabrics that have been used extensively in recent years are chosen to investigate the effects of their properties on flame resistance. Physical parameters (fiber type and composition, yarn count, yarn twist coefficient, fabric design, weight per unit area, air permeability, fabric thickness, cov…
This article presents the application of a three-dimensional finite-element solution algorithm for the prediction of velocity and temperature fields in an industrial continuous galvanizing bath. The effect of line speed, strip width, strip temperature, and inductor mixing are evaluated. Simulations were carried out us…
Abstract The effects of a subvolcanic intrusion on its host rocks in the Priego de Córdoba area (SE Spain) was studied by optical microscopy, X-ray diffraction and electron microscopy. The intrusion of a laccolith of stratiform dolerite in partially consolidated marly sediments at quite shallow depths below the ocean…
Abstract A series of hyperbranched aromatic polyamide copolymers has been prepared and characterized from direct polycondensation of AB 2 and AB monomers. Structure of the monomers and the molar ratio of AB 2 /AB showed strong influence on the properties of resulting copolymers. A small amount of AB 2 branching unit i…
Lithium-doped zinc oxide (ZnO) films were prepared on C-plane sapphire substrates by the e-beam deposition technique in vacuum. The dependences of the optical absorption edge characteristics, structural, and photoelectrical properties on Li content (from 0 to 10 at.%) were investigated. It is found that the variations…
The potential shortage of allograft bone has led to the need to investigate other sources of bone for allografts. Some allograft bone donated from primary total hip arthroplasty recipients must be discarded or treated to become usable as a result of bacterial contamination. Femoral head allografts were contaminated wi…
Abstract In this paper, hyperbranched polyimides having the same repeating unit were synthesized by employing ideal A 2 +B 3 polymerization, non‐ideal A 2 +B 3 polymerization and AB 2 self‐polymerization methods. The polymerization behavior, polymer properties were compared for three methods. Hyperbranched polyimides…
S-shaped kinetic curves are very frequent in nature. Based on our own experimental evidence on the growth of single dendrites and analysis of literature data, we have demonstrated that such curves may result from the maximum entropy production principle. The proposed approach also explains other prevalent laws of rela…

The Crabtree-negative yeast Kluyveromyces lactis is capable of adjusting its glycolytic flux to the requirements of respiration by tightly regulating glucose uptake. RAG5 encoding the only glucose and fructose phosphorylating enzyme present in K. lactis is required for the up-regulation of glucose transport and also f…
Abstract Octadecylamine (ODA) was used to intercalate a fine-grained and a coarse-grained fraction of natural Mg-vermiculite (VER) using a low-temperature melting procedure. Mixtures of Mg-vermiculite fractions and powdered ODA in the molar ratios of 2:1, 1:1, 1:2 and 1:6 were homogenized and heated for 1, 3, 15 and 3…
The effects of Dy co-doping on the thermoluminescence (TL) characteristics of LiNaSO4:Eu phosphor are studied. Energy transfer from Eu2+ to Dy3+ results in a decrease in TL peak intensity suggesting that Dy3+ plays a negative role in TL emission in the present matrix. However, though Dy3+ acts as a quencher, it helps…
This paper addresses the off-design analysis of a hybrid system (HS) based on the coupling of an existing Ansaldo Fuel Cells (formerly Ansaldo Ricerche) molten carbonate fuel cell (MCFC) stack (100 kW) and a micro gas turbine. The MCFC stack model at fixed design conditions has previously been presented by the authors…
This short account demonstrates that ferrocene is a valuable unit for the elaboration of functional liquid-crystalline materials: 1) its three-dimensional structure allowed a clear structure-mesomorphic behavior relationship in the case of mono-, di-, and poly-substituted ferrocene-containing liquid crystals to be est…
Abstract The deformation of the dispersed phase in polystyrene/high density polyethylene (PS/HDPE) blends produced by ribbon extrusion was studied numerically and experimentally. A mathematical model for the deformation of the dispersed phase in ribbon extrusion processing of polymer blends was developed assuming unia…
Abstract A possible structural change in Sr 0.66 Ba 0.34 Nb 2 O 6 single‐crystal fibers when the temperature decreases from 295 to 10 K was investigated by dielectric constant measurements and Raman spectroscopy. An anomaly observed in the dielectric constant and the loss factor is associated with the variation in the…
Electromigration due to insufficient wire width can cause the premature failure of a circuit. The ongoing reduction of circuit feature sizes has aggravated the problem over the last couple of years, especially with analog circuits. It is therefore an important reliability issue to consider current densities already in…
We have determined the equation of state of phase Egg, AlSiO 3 OH, at room temperature up to 40 GPa, using X-ray powder diffraction with synchrotron radiation. We determined the isothermal bulk modulus K 0T = 157 ± 4 GPa with a pressure derivative K' 0T = 6.5 (4) by fitting a third order Birch- Murnaghan equation of s…
Kupcikite, Cu 3 . 4 Fe 0 . 6 Bi 5 S 1 0 , a new mineral species, is found in the scheelite deposit of Felbertal, Austria, in a quartz gangue, in association with chalcopyrite, pyrrhotite, molybdenite, sphalerite and native bismuth, intergrown with makovickyite, cupromakovickyite, hodrushite, cuprobismutite and derivat…
Ganterite, [Ba 0.5 (Na,K) 0.5 ]Al 2 (Si 2.5 Al 1.5 O 10 )(OH) 2 , the barium-dominant analogue of muscovite, was discovered in the crystalline basement rocks of the Berisal Complex, Simplon Region, Switzerland. Examples of this new rock-forming mica are found in bands and lenses of white-mica schist, and in a leucocra…
