Influence of hemicelluloses and lignin content on structure and sorption properties of flax fibers (Linum usitatissimum L.)
(Springer, Dordrecht, 2018)
In this work, alkali and oxidative treatments were employed to obtain flax fibers with different content of hemicelluloses and lignin, in order to study the influence of chemical composition on structure and sorption ...
Recent advances in homogeneous and heterogeneous asymmetric catalysis with nitrogen-containing ligands
(Baltzer Sci Publ Bv, Bussum, 1997)
Nitrogen-containing chiral ligands are being used more and more in asymmetric catalysis. This article is an overview of results published in 1993-1996 in this field and tries to open new perspectives for this type of ligand, ...
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 ...
The influence of a cryoprotective medium containing glycerol on the lyophilization of lactic acid bacteria / Uticaj krioprotektivnog medijuma sa glicerolom na liofilizaciju bakterija mlečne kiseline
(Serbian Chemical Society, 2001)
The aims of lyophilization (freeze-drying) of lactic acid bacteria are to preserve pure cultures or to prepare starters for the dairy industry. In both cases, the choice of the cryoprotectant is very important. In this ...
Principal component analysis of trace elements in industrial soils
(Springer Heidelberg, Heidelberg, 2004)
The concentrations of the elements Cr, Pb, Cd, Zn, Ni, Mn, Cu and As in soil samples from industrial areas in Serbia were studied. The complexity of the data of eight elements in fifty-nine soil samples was reduced by ...
Impact of plate types on refining and specific energy consumption
(Editura Acad Romane, Bucuresti, 1998)
Fibre refining is one of the most important stages of mechanical and chemical fibre treatment with direct impact on the quality of the final product-paper. The raw material to be refined and the requirements regarding the ...
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 ...
Osmotic and activity coefficients of the {xZnCl(2)+(1-x)ZnSO4}(aq) system at 298.15 K
(Springer/Plenum Publishers, New York, 2007)
Isopiestic vapor pressure measurements were made for {xZnCl(2)+(1-x)ZnSO4}(aq) solutions with ZnCl2 molality fractions of x=(0,0.3062,0.5730,0.7969, and 1) at the temperature 298.15 K, using KCl(aq) as the reference standard. ...
Study of interaction between nitrogen DBD plasma-treated viscose fibers and divalent ions Ca2+ and Cu2+
(Springer, Dordrecht, 2014)
Viscose fibers were treated with atmospheric pressure dielectric barrier discharge (DBD) plasma obtained in nitrogen in order to activate the fiber surface prior to sorption of the divalent ions Ca2+ and Cu2+. Methylene ...
