Одређивање састава чврстих раствора ромбичних карбоната помоћу кристалографских параметара, део IV : Математички прорачуни за CaCO3-SrCO3-PbCO3 систем : (са 14 табела) / Determination of the composition of the otrhorhombic carbonate solid solutionswith crystallographic parameters, part IV : Mathematical calculations for the CaCO3-SrCO3-PbCO3 system : (with 14 Tables)
(Геозавод, 2005)
There were calculated contents of the phases with smaller ionic radius in the CaCO3-SrCO3, CaCO3-PbCO3 and SrCO3-PbCO3 systems for the three-component CaCO3-SrCO3-PbCO3 system.
Results of these mathematical calculations ...

Syntheses of Tetrahydro-β-Carbolines via Tandem Hydformylation / Pictet-Spengler Reaction, Scope and limitations
(Royal Society of Chemistry, 2008)
A novel one-pot synthesis of tetrahydro-β-carboline systems via tandem hydroformylation–Pictet–Spengler reaction starting from olefins and aryl ethylamines is described. This tandem procedure allows fast and convenient ...
