Osmotic and activity coefficients of {yNaH(2)PO(4)+(1-y)Na2SO4}(aq) at the temperature 298.15 K
(Elsevier Science Bv, Amsterdam, 1999)
The osmotic coefficients of the mixed electrolyte solution {yNaH(2)PO(4) + (1 - y)Na2SO4}(aq) have been measured by the isopiestic method, at the temperature T = 298.15 K. The activity coefficients of NaH2PO4 and Na2SO4 ...
Electrical resistance of cotton-metal fibre yarns
(Inst Chemical Fibres, Lodz, 1999)
Yarns representing cotton-metal fibre blends were studied. The electrical resistance of yarns including different fractions of cotton and metal fibres was compared with cotton yarns having the same nominal characteristics. ...
Regulation of the crystallization in a crucible furnace
(Elsevier, Amsterdam, 1999)
A model of an air cooler ("cold finger") in a laboratory crucible furnace, for simultaneous regulation of scaling intervals of the crystallization rate in a series of Tamman test tubes with the purpose of obtaining crystals, ...
Effect of substituents on the C-13 chemical shifts of the azomethine carbon atom of N-(phenyl substituted) pyridine-4-aldimines
(Elsevier, Amsterdam, 1999)
C-13 chemical shifts of the azomethine carbon atom for N-(substituted phenyl)pyridine-4-aldimines, 4-Py-CH=N-C6H4-X, X having a wide range of substituent effects, have been determined in CDCl3 solution. Exceptionally good ...
Microstructural characteristics of calcium hydroxyapatite/poly-L-lactide based composites
(Wiley, Hoboken, 1999)
Besides its high osteoinductive properties, hydroxyapatite (HAp) exhibits a relatively low mechanical strength. In order to improve the mechanical properties and reliability of HAp based composites, the addition of selected ...
Rheological study of the copolymerization reaction of acrylate-terminated unsaturated copolyesters with styrene
(Wiley-VCH Verlag Gmbh, Weinheim, 1999)
The free radical copolymerization reaction of three series of acrylate-terminated unsaturated polyesters with styrene, using benzoyl peroxide/N,N-dimethylaniline as the redox initiator system, was followed by dynamic ...
Technetium-99m labeling of hippuric and p-amino-hippuric acid in the presence of DTPA: Biological and pharmacokinetic evaluation and comparison with Tc-99m-DTPA
(Springer, Dordrecht, 1999)
Tc-99m-Hipp as a modified Tc-99m-DTpA, and Tc-99m-PAH as a new renal agent are developed. Each veal of lyophilised kit contain hippuric (Hipp) or p-aminohippuric acid (PAH), diethyltriaminepentaacetic acid as calciumtrisodium ...
Wool fabric characterisation after enzymatic and chlorinating treatment / Karakterizacija vunenog tekstilnog materijala posle enzimske obrade i obrade hlorovanjem
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 1999)
Properties of wool textile products are partly governed by morphological composition and chemical structure of the surface of wool fibre. Both chemical structure and morphological composition are most frequently changed ...
Determination of multiaxial stress linear dimensional change of textile surfaces / Određivanje promene linearnih dimenzija tekstilnih površina pri multiaksijalnom naprezanju
(Savez inženjera i tehničara tekstilaca Srbije, 1999)
Breaking characteristics of loose woven and knitted fabrics are frequently determined by the ball penetration resistance (bursting) (test). The Yugoslav Standard JUS F.S2.022 does not include the determination of sample ...
Solvent effects on electronic absorption spectra of 3-N-(4-substituted-phenyl)-5-carboxy uracils
(Serbian Chemical Society, Belgrade, 1999)
Absorption spectra of some 3-N-(4-substituted phenyl)-5-carboxy uracils (substiuents: H, Cl, Br, I, Me, Et, OMe, COOH and NO2) were recorded in twelve solvents in the range 200-400 nm. The effects of solvent polarity and ...
