Deformation pattern and strain hardening in a highly textured 8090 Al-Li alloy sheet
(Elsevier Science Sa, Lausanne, 2000)
Structure-deformation pattern analysis was made on a highly textured 8090 AI-Li alloy sheet deformed in tension. It is shown that the sharp beta-fiber type crystallographic texture induces a strong orientation variation ...
Influence of different iron powders on the friction properties of sintered friction materials based on iron
(Elsevier Science B.V., 2000)
The possibility of using iron powders of different morphological, chemical and physical properties as the bases of the metal matrix of the friction layer in sintered friction materials for dry friction under severe braking ...
Mass spectrometry analysis of polychlorinated biphenyls: Chemical ionization and selected ion chemical ionization using methane as a reagent gas
(Serbian Chemical Society, 2000)
In the present paper a quadrupole ion trap mass spectrometer, coupled with a gas chromatograph, was used to compare the electron impact ionization (El) and chemical ionization (Cl) technique, in terms of their selectivity ...
Kinetics and mechanism of the reaction of substituted 4-pyrimidine carboxylic acids with diazodiphenylmethane in dimethylformamide
(Scientific Reviews Ltd., 2000)
Correlation of the data for the reaction of 11 substituted 4-pyrimidine carboxylic acids with diazodiphenylmethane (DDM) in dimethylformamide (DMF) with calculated atomic charges on the carboxylic group showed that the ...
Approach to laminar phenomena occurring on external and internal surfaces of solid specimens
(Kluwer Academic Publishers, 2000)
This article presents a general mathematical model for describing the laminar transport phenomena during homogeneous/heterogeneous appearances in the neighborhood of external and internal surfaces of small solid specimens. ...
Thermal investigation of two FePO materials prepared in the presence of 1,2-diaminoethane
(Elsevier, Amsterdam, 2000)
Two porous iron phosphates were synthesized hydrothermaly from a reaction mixture of FeCl3:H3PO4:1,2-diaminoethane:H2O in the molar ratio 1:3:5:70. The chemical formulas indicate difference only in water content; however, ...
Physical-mechanical phenomenon of woven and non-conventional materials
(Emerald Group Publishing Limited, Bradford, 2000)
The basic idea of this project is in developing series of methods for monitoring structural parameters, as well as establishing their relation with the behaviour of woven and non-woven materials. Establishing the connection ...
Study of chlorination of nickel silicate by gaseous chlorine and calcium chloride in the presence of active additives
(Wiley, Hoboken, 2000)
The paper presents a thermodynamic analysis and experimental research on the kinetics of the chlorination of nickel silicate (2NiO x SiO2) by gaseous chlorine and calcium chloride without additives and in the presence of ...
Have you ever thought about mole and its place in the international system of units? / Da li ste ikada razmišljali o molu i njegovom mestu u međunarodnom sistemu jedinica?
(Srpsko hemijsko društvo, Beograd, 2000)
A short historical review of measuring and units has been given in the first part of this paper. The most attention has been paid to the decimal metric system and to the development of International system of units (SI). ...
The use of shade sorting method for the fabrics in garment manufacture / Primena metode sortiranja nijansi tkanine za izradu odevnih predmeta
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2000)
Shade sorting methods are designed with the aim to identify the pieces i.e. coloured materials from different dyelots, that could be used for the manufacture of a single garment in order to keep the colour difference between ...
