Influence of composition of the magnetic composite coating on the performance of the optical fiber magnetic field sensing element
(Natl Inst Optoelectronics, Bucharest-Magurele, 2007)
The optical fiber magnetic sensing element (OFMSE) based on the optical fiber coated with composite coating polymermagnetic powder has been already introduced in magnetic field sensing. In this research, the rapid quenched ...
The effect of substrate polarity on the lipase-catalyzed synthesis of aroma esters in solvent-free systems
(Elsevier, Amsterdam, 2007)
The aim of this study was to compare activities of commercial lipases in synthesis of various esters in solvent-free system and in isooctane. Moreover, the effect of substrate polarity (expressed as log P) on solvent-free ...
Total lipids of the intramuscular tissue of fallow deer - Non-isothermal, non-oxidative and oxidative TG
(Springer, Dordrecht, 2007)
In this study non-isothermal non-oxidative and oxidative TG analysis was applied as a method for determining the thermal stability of the total lipids extracted from raw and maturing intramuscular tissue of fallow deer ...
Doped gamma-Bi2O3: synthesis of microcrystalline samples and crystal chemical analysis of structural data
(Walter de Gruyter Gmbh, Berlin, 2007)
A series of microcrystalline products containing the gamma-Bi2O3 phase doped with Co, Fe, Mn, Pb, Sb, Si, Ti, V and Zn has been prepared by solid state reaction. Based on the heating temperature and heating time, the ...
Ca-alginate hydrogel mechanical transformations - The influence on yeast cell growth dynamics
(Elsevier, Amsterdam, 2007)
A mathematical model was formulated to describe yeast cell growth within the Ca-alginate microbead during air-lift bioreactor cultivation. Model development was based on experimentally obtained data for the intra-bead cell ...
Adhesion and corrosion resistance of epoxy primers used in the automotive industry
(Taylor & Francis Ltd, Abingdon, 2007)
One of the most important factors in corrosion prevention by protective coatings is the loss of adhesion of the coating under environmental influence. Thus, adhesion strength is often used when characterizing protective ...
Swelling and drug release behavior of poly(2-hydroxyethyl methacrylate/itaconic acid) copolymeric hydrogels obtained by gamma irradiation
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
The new copolymeric hydrogels based on 2-hydroxyethyl methacrylate (HEMA) and itaconic acid (IA) were prepared by gamma irradiation, in order to examine the potential use of these hydrogels in controlled drug release ...
Investigation of Ca-alginate hydrogel rheological behaviour in conjunction with immobilized yeast cell growth dynamics
(Taylor & Francis Ltd, Abingdon, 2007)
The rheological model is developed to elucidate the mechanism of Ca-alginate microbead deformation in the course of cell growth within. It is a complex process influenced by relaxation of the expanded polymer network inside ...
Mathematical modeling of insulin sorption by ion-exchange fiber
(John Wiley & Sons Inc, Hoboken, 2007)
The objective of this study was to investigate the phenomenon and kinetics of insulin chemisorption by cation-exchange acrylic fibers, as well as the development of theoretical modeling of the chemisorption process. Change ...
Investigation of the electrical behavior of some textile materials
(Elsevier, Amsterdam, 2007)
Some electrophysical properties of textile samples having different forms and raw material compositions were studied. For determining the electric resistance, a measuring device, based on the measurement of direct current ...
