The effect of growth rate on the structure of primary and secondary dendrites of single crystal of Ni based superalloy
(Trans Tech Publications Ltd, Durnten-Zurich, 1998)
So far, in our work aimed at obtaining single crystals of a Ni based superalloy, we have investigated the possibilities of obtaining single crystals using different methods as well as the influence of growth conditions, ...
2D model of pseudomorphic InGaAs/InAlAs HEMT's structure
(Trans Tech-Scitec Publications Ltd, Durnten-Zurich, 1998)
This paper presents the 2D model of the pseudomorphic InGaAs/InAlAs/InGaAs HEMT (High Electron Mobility Transistor) structure based on relevant physics. Together with parameters governed by the geometry and the producing ...
Some applications of optical fibres in medicine and disturbances in biomedical area
(5th Congress on Modern Optics, OPTIKA 1998, 1998)
The development of medical equipment, telecommunications and computer's technology provides new possibilities for diagnostic purposes. Usually, it is necessary to use optical image or noise transmission. The application ...
Dynamic cell seeding of polymer scaffolds for cartilage tissue engineering
(Wiley, Hoboken, 1998)
Cell seeding of three-dimensional polymer scaffolds is the first step of the cultivation of engineered tissues in bioreactors. Seeding requirements of large scaffolds to make implants for potential clinical use include: ...
Condensation of 1,3-diketones with cyanoacetamide: 4,6-disubstituted-3-cyano-2-pyridones

Kinetics of lipase-catalyzed hydrolysis of palm oil in lecithin/izooctane reversed micellles
(Springer, New York, 1998)
Candida rugosa lipase has been used to investigate the hydrolysis of palm oil in a lecithin/isooctane reversed micellar system. The reaction obeys Michaelis-Menten kinetics for the initial conditions. Kinetic parameters ...
Stress state effect on dynamic strain aging and surface markings during stretching of AlMg7 alloy sheet
(Trans Tech Publications Ltd., 1998)
Stress state effect on dynamic strain aging (DSA) and the related surface appearance was analyzed in uniaxial and biaxial room temperature stretching of AlMg7 alloy sheet. In uniaxial tension the serrated yielding was found ...
The use of chitosan on hydrogen peroxide pretreated wool
(Amer Assoc Textile Chemists Colorists-Aatcc, Res Triangle Pk, 1998)
Since chlorination is known to produce substantial pollution with adsorbable organo halogens (AOX) in textile wastewater, shrink resist treatments like the widely used chlorine/Hercosett process are no longer environmentally ...
Mathematical modelling and simulation of drawing thin glass sheet from a rectangular preform
(Glass Technology, 1998)
A mathematical model of thin glass sheet drawing has been developed This model includes momentum, heat and mass balance equations The density, viscosity and specific heat of the glass were calculated as functions of ...
Synthesis and rheological study of some maleic acid and fumaric acid stereoregular polyesters, 10 - Synthesis and characterization of alpha,omega-dihydroxyoligo(alkylene maleate)s
(Wiley-VCH Verlag Gmbh, Weinheim, 1998)
alpha,omega-Dihydroxyoligo(alkylene maleate)s with molecular weights ranging from 1500 to 4000 were prepared by polycondensation, in 1-methyl-2-pyrrolidone at 105 degrees C, of potassium maleate and 1,4-dibromobutane, ...
