The drying of solids in a cross ow conveyor belt dryer (continuous operation system), in which particles (thin-layer) move in a wire net conveyor, was theoretically studied. A mathematical modeling that considers the ...

TiCl3(OTf) catalyzed e ciently the protection of aromatic aldehydes with acetic anhydride in the absence of solvent at room temperature with excellent yields. By this method, aliphatic aldehydes were also converted to ...

Methanol has been of great interest as a substrate for production as a novel feed grade protein in Iran. Up to 160 methylotrophic strains were isolated at the Jahad-e Agriculture Research Engineering Center for Scienti ...

Nowadays, neural networks have a wide range of usage in di erent elds of engineering. In the present work, this method is used to determine a reservoir model. Model identi cation, followed by parameter estimation, is a ...

A new chromate-selective electrode, based on the N, N' butylen bis (saliciliden iminato) copper (II) complex as the membrane carrier, was developed. The electrode exhibited a good Nernstian slope of ????28:8 0:5 mV/decade ...

Al(HSO4)3 as an acidic salt, i.e. a mild, convenient and e cient reagent, was applied for the conversion of compounds containing a hydroxyl group to primary carbamates, at room temperature, with high yield and purity and ...

Alcohols and trimethylsilyl and tetrahydropyranyl ethers are e ciently oxidized to their corresponding carbonyl compounds, using Fe(NO3)3.9H2O, in the presence of KBr, under mild and completely heterogeneous reaction ...

The compound, alkaline lead acetate, Pb(CH3COO)2 :PbO:H2O (ALA), was purchased from the Fluka Company. The X-ray di raction lm and SEM electron microgaph of this compound were obtained and reported in this paper for ...
