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 ...
Application of the MvdW1 and HVOS-NRTL mixing rules to the simultaneous correlation of excess enthalpies and W-shaped excess heat capacities data of 1,3-dioxolane plus n-alkane systems
(Serbian Chemical Society, Belgrade, 1999)
The Peng-Robinson-Stryjek-Vera (PRSV) equation of state (EOS) coupled with a modified two parameter van der Waals one-fluid mixing rule (MvdW1) and the Huron-Vidal-Orbey-Sandler mixing rule incorporating the NRTL equation ...
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 ...
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 ...
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 ...
Gas exchange is essential for bioreactor cultivation of tissue engineered cartilage
(John Wiley & Sons Inc, New York, 1999)
Tissue engineered cartilage can be grown in vitro if the necessary physical and biochemical factors are present in the tissue culture environment. Cell metabolism and tissue composition were studied for engineered cartilage ...
EXAFS and XANES study of the incorporation of Mn cations into a chabazite-like AlPO molecular sieve
(Int Union Crystallography, Chester, 1999)
The incorporation of Mn(II) cations into a chabazite-like MnAlPO material is studied with Mn K-edge XANES and EXAFS. Both methods show that Mn(II) is inserted exclusively into the tetrahedrally coordinated aluminum sites. ...
Method for quantitative analysis of glycosaminoglycan distribution in cultured natural and engineered cartilage
(Amer Inst Physics, Woodbury, 1999)
Cartilage tissue engineering can provide a valuable tool for controlled studies of tissue development. As an example, analysis of the spatial distribution of glycosaminoglycans (GAG) in sections of cartilaginous tissues ...
The electro-oxidation of H-2 and H-2/CO mixtures on carbon-supported PtxMoy alloy catalysts
(Electrochemical Soc Inc, Pennington, 1999)
Electro-oxidation kinetics of H-2 and H-2/CO mixture were studied on bimetallic Pt-Mo catalysts supported on a high-surface-area carbon black. The Pt:Mo atomic ratios in the catalysts were 3:1 and 4:1. Characterization of ...
