The effect of the particle shape and structure on the flowability of electrolytic copper powder I: Modeling of a representative powder particle / Uticaj oblika i strukture čestica na tečljivost elektrolitičkog bakarnog praha I - modelovanje reprezentativne čestice praha
(Serbian Chemical Society, 2003)
One of the most important properties of copper powder is its flow ability which depends on the shape and the structure of the powder particles. A procedure for the determination of a representative powder particle permitting ...
Oxidative fragmentation of 5-hydroxy-1-oxo-5α-cholestan-3β-yl acetate / Oksidativne fragmentacije 5-hidroksi-1-okso-5α-holestan-3β-il-acetata
(Serbian Chemical Society, 2003)
5-hydroxy-1-oxo-5α-cholestan-3β-yl acetate (11) was prepared in 5 steps starting from (E)-3β-acetoxy-5,10-seco-1(10)-cholesten-5-one (6). Treatment of the 1-oxo-5-hydroxy derivative 11 with lead tetraacetate (LTA) (under ...
The effect of the particle shape and structure on the flow ability of electrolytic copper powder II: The experimental verification of the model of the representative powder particle / Uticaj oblika i strukture čestica na tečljivost elektrolitičkog bakarnog praha II - eksperimentalna potvrda modela reprezentativne čestice praha
(Serbian Chemical Society, 2003)
An analysis of the effects of the shape, surface structure and size distribution of particles on the flow ability of the copper powder was performed. It is shown that the most important property of the particles of a powder, ...
The effect of preparation of aluminum surface on the structure of final coating of nickel / Uticaj pripreme površine aluminijuma na strukturu završne prevlake nikla
(Belgrade, Serbia : Engineering Society for Corrosion, 2003)
In this work structure characteristics of the final coating of nickel were studied. Nickel was deposited onto chemically prepared aluminum, chemically and electrochemically. Structural characteristics of metallic coatings ...
The effects of nitric oxide (NO) and peroxynitrite on MnSOD (E.coli)
(Turkish Biochemical Society, 2003)
Our results demonstrate that MnSOD (E. coli)-stimulated generation of NO+ and NO- species is associated with nitration of enzyme tyrosine residues and dityrosinc formation, which cause enzyme inactivation. This represents ...
Insulin-activated gpi-transamidase in human erythrocytes
(Turkish Biochemical Society, 2003)
Our results demonstrate that exposure of erythrocyte membranes to insulin cause the activation of membrane protease, as well as that the formation of GPI-Hb parallels its activity. This, together with recent findings ...
Cholesterol bound to hemoglobin in normal human erythrocytes
(Turkish Biochemical Society, 2003)
Our results demonstrate that in contrast to Ch and PL contents of RBC membrane which are confined to a narrow range, the lipid levels estimated in intact RBCs showed more variation: the lowest individual values for RBC ...
X-ray investigations of scheelite and pyrite from Aldinac (Stara Planina Mt.)
(Geoinstitut, 2003)
At one representative sample there was indiced powder diffraction pattern and done qualitative-semiquantitative X-ray powder diffraction analysis. It was established that the investigated sample contains scheelite and ...
Појава церузита из рудног поља рупља (ЈИ Србија) / Cerussite occurrence from Ruplje ore field (SE Serbia)
(Геозавод, 2003)
Ispitivana je nova pojava ceruzita iz Ruplja rudno-mikroskopskim i rendgenskim metodima.
U ispitivanom uzorku utvrđeno je dominantno prisustvo ceruzita i kvarca i vrlo malo glina-liskuna, kao i ukupno oko 5% rudnih ...
Одређивање састава чврстих раствора ромбичних карбоната помоћу кристалографских параметара, део I: теорија, могућности и математички прорачуни за систем CaCO3-SrCO3 / Determination of the composition of the orthorhombic carbonate solid solutions with crystallographic parameters, Part I: Theory, possibilities and mathematical calculations for the CaCO3-SrCO3 system
(Геозавод, 2003)
Ispitivane su mogućnosti određivanja sastava čvrstih rastvora rombičnih karbonata pomoću kristalografskih parametara. Ako se kristalografski parametri menjaju linearno sa sastavom, i ako je ta zavisnost duž linije koja ...
