Selenium in food and population of Serbia
(Royal Society of Chemistry, 1996)
Selenium (Se) is an essential trace elements for animals and humans, but not for
plants. The quantity of Se in food and feed is strongly dependent on the concentration in
plants, that is the main source of selenium, for ...
Acid-catalyzed rearrangement of some steroidal isoxazolidines
(Elsevier, 1999)
Acid-catalyzed reaction of the steroidal Δ 1 -unsaturated 3β,5β- epoxyimino compound 2 and Δ 3 -unsaturated 1β,5β-epoxyimino products 3 and 7, results in intramolecular rearrangement involving the N-CH 3 group to give the ...
Surface characterization of oxidized activated carbon cloth
(Elsevier, 1997)
Cellulose based activated carbon cloth has been oxidized by air, nitric acid, hydrogen peroxide and iron nitrate cristallohydrate melt treatments. Thermogravimetric analysis, selective neutralization, X-ray photoelectron ...
Steroidal geminal dihydroperoxides and 1,2,4,5-tetraoxanes: Structure determination and their antimalarial activity
(Elsevier, 1996)
Cholestane-derived gem-dihydroperoxides and tetraoxanes were synthesized starting from 5e~- and 5~3-cholestan3-ones by acid-catalyzed addition of hydrogen peroxide to the ketone. They were characterized by IR, NMR, and
mass ...
Synthesis, crystal structure, magnetic properties and cyclic voltammetry of the unsymmetric (μ-oxalato)-[N,N′,N″,N‴-tetrakis-(2-pyridylmethyl)-1,4,8, 11-tetraazacyclotetra-decane]dicobalt(II) perchlorate trihydrate
(Taylor and Francis, 1999)
A new dinuclear cobalt(II) complex, [Co2(ox)tpmc](ClO4)2 3H2O, (tpmc = N, N′, N″, N″′-tetrakis(2-pyridylmethyl)-1, 4, 8, 11-tetraazacyclotetradecane, ox2 -oxalate ion), has been synthesized and its crystal structure solved ...
Electron‐impact induced decomposition of some 3‐alkyl‐5‐substituted‐6‐methyl uracils
(John Wiley & Sons, 1995)
Mass spectrometry was used to study the main fragmentation routes of some 3‐alkyl‐5‐substituted‐6‐methyl uracils. Differences in fragmentation were caused by changes in the structure of the alkyl group in position 3 of the ...
Synthesis and dopaminergic properteis of 3- and 4-substituted 1-{-[5-(1H-benzimidazole-2-thione)]ethyl}piperidines and related compounds
(Wiley, 1997)
With an aim of creating new, high affinity dopaminergic ligands, six different 3- and 4-substituted 1-{2-[5-(1H-benzimidazole-2-thione)]ethyl}piperidines and nine related heterocyclic congeners were synthesized and evaluated ...
Triterpenoids from Hieracium plumulosum A. Kerner, L., Asteraceae
(Govi-Verlag Pharmazeutischer Verlag GmbH, 1996)
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 ...
Electrosorption of hydrogen and sulfuric acid anions on single crystal platinum stepped surfaces. Part II. The [110] zone
(Elsevier, 1991)
Hydrogen and bisulphate adsorption at platinum single crystal surfaces from the [ITO] zone is
strongly dependent on the crystallographic orientation of the electrode surface, which is similar to that
found earlier for ...
