Influence of the electrode parameters on pulse shape characteristic of gas-filled surge arresters at small pressure and inter-electrode gap values
(IEEE-Inst Electrical Electronics Engineers Inc, Piscataway, 2005)
The aim of this paper is to present the influence of electrode system parameters on electrical breakdown of gas (electrode effect) with the purpose to improve the gas-filled surge arresters (GFSAs) protective characteristics ...
Synthesis of new hyperbranched urethane-acrylates and their evaluation in UV-curable coatings
(Elsevier Science Sa, Lausanne, 2004)
Three series of hyperbranched urethane-acrylates (HB-UA), based on aliphatic hyperbranched polyesters and polyethyleneglycol acrylate, were prepared and evaluated for use in UV-curable coatings. UV-curing kinetics were ...
A Comparative LSER Study of the Reactivity of 2-Substituted Cyclohex-1-eneacetic and 2-Substituted Phenylacetic Acids with Diazodiphenylmethane in Various Solvents
(Wiley, Hoboken, 2009)
The rate constants for the reaction of 2-substituted cyclohex-1-eneacetic and 2-substituted phenylacetic acids with diazodiphenylmethane were determined in various aprotic solvents at 30 degrees C. To explain the kinetic ...
Trace elements analysis of Echinacea purpurea - herbal medicinal
(Elsevier, Amsterdam, 2003)
Elemental composition of Echinacea purpurea (Asteracae), grown in Serbia under strongly controlled conditions, has been studied. To distinguish elemental patterns of different parts of the plant, the content of Zn, Fe, Cu, ...
Thermodynamic modeling of vapor-liquid equilibria and excess properties of the binary systems containing diethers and n-alkanes by cubic equation of state
(Korean Institute Chemical Engineers, Seoul, 2004)
A comparison of the performances of two different approaches of cubic equations of state models, based on a classical van der Waals and mixing rules incorporating the G(E) equation, was carried out for correlation of ...
Application of nonlinear frequency response to investigation of membrane transport
(Taylor & Francis Inc, Philadelphia, 2006)
The concept of higher order frequency response functions, used for investigation of weekly nonlinear systems by frequency response techniques, is applied to investigation of membrane systems. Isothermal permeation of single ...
Classification of soil samples according to their geographic origin using gamma-ray spectrometry and principal component analysis
(Elsevier Sci Ltd, Oxford, 2006)
A principal component analysis (PCA) was used for classification of soil samples from different locations in Serbia and Montenegro. Based on activities of radionuclides (Ra-226, U-238, U-235, K-40, Cs-134, Cs-131, Th-232 ...
Synthesis, structure, and thermal properties of two new inorganic-organic framework compounds: Hexaaqua(mu(2)-1,2,4,5-benzenetetracarboxylato)-bis(N,N '-1,10-phenathroline)dicobalt(II) dihydrate and hexaaqua(mu(2)-1,2,4,5-benzenetetracarboxylato)-bis(N,N
(Wiley-VCH Verlag Gmbh, Weinheim, 2006)
Two binuclear complexes [Co-2(C10H2O8)(C12H8N2)(2) (H2O)(6)]center dot 2H(2)O (1) and [Ni-2(C10H2O8)(C10H9N3)(2)(H2O)(6)]center dot 4H(2)O (2) were synthesized and their structures were determined by X-ray structure analysis. ...
Prediction for debonding damage process of glass beads-reinforced modified polyphenylene oxide under simple shear
(Elsevier Science Sa, Lausanne, 2005)
A three-dimensional finite element cell modeling technique has been applied to predict the particle-matrix debonding process of particulate polymer composite (PPC) subject to simple shear loading. The particle-matrix ...
Effect of substituents on the C-13 chemical shifts of the azomethine carbon atom of N-(phenyl substituted)pyridine-3-and-2-aldimines
(Elsevier, Amsterdam, 2002)
C-13 chemical shifts of the azomethine carbon atom for N-(phenyl substituted)pyridine-3-aldimines, 3-Py-CH=N-C6H4-X, and N-(phenyl substituted)pyridine-2-aldimines, 2-Py-CH=N-C6H4-X, having a wide range of substituent ...
