Modeling of drawing thin glass sheet from a preform / Model izvlačenja tankih staklenih traka iz predoblika
(Serbian Chemical Society, 1998)
A one-dimensional model of thin glass sheet drawing has been developed. This model includes momentum, heat and mass balance equations. The density, viscosity and specific heat of the glass were calculated as functions of ...
Covalent glycophospholipid binding to hemoglobin. A new post-translational modification occurring in erythrocytes exposed to insulin
(Serbian Chemical Society, 1996)
In this work a novel hitherto unrecognised hemoglobin (Hb) fraction, HbA1x, which we detected previously in hemolysates of erythrocytes exposed to high concentration of insulin under hypoglycemic conditions, both in vivo ...

Free radical ring expansion and subsequent reactions of intermediary carbon radicals
(Serbian Chemical Society, 1996)
Alkyl radicals, derived from ethyl 1-(bromoalkyl)-2-oxocyclo-alkanecarboxylates or from the corresponding thiohydroxamic esters, undergo a ring expansion reaction and subsequent intermoleculaar addition/elimination reactions. ...
