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 ...
An improved approach to B-norsteroids: An one-pot preparation of 3β-acetoxy-5-oxo-5,6-seco-cholestan-6-oic and 3β-acetoxy-5,17-dioxo-5,6-seco-androstan-6-oic acids
(Serbian Chemical Society, 1998)
A simple one-put procedure for the synthesis of the 5,6-seco-steroidal acids 9a,b in described in this paper. It consists of the epoxidation of the ▲ 5 -steroids, i.e., cholesteryl acetate (8a) and 17-oxo-aandrost-5-en-3β-yl ...
Sesquiterpene lactones from plant species Centaurea solstitialis L.
(Serbian Chemical Society, 1998)
The identification of nine known guaianolides, i.e., solstitialin A, its 13-acetate, linichlorin B, cynaropicrin, centaurepensin (chlorohyssopifolin A), 17-epi-centaurepensin, 19-desoxychlorojanerin, 11ß,13-dihydrodesacy ...
Synthesis and oxidative transformations of 5-hydroxy-5α-cholest-8-en-3β-yl acetate
(Serbian Chemical Society, 1997)
5-Hydroxy-5α-cholest-8-en-3β-yl acetate (8) (prepared in 6 steps starting from 7-dehydrocholesteryl acetate (1) was transformed with ruthenium tetroxide to 5-hydroxy-8,9-dioxo-8,9-seco-5α-cholestan-3β-yl acetate (9). ...
Synthesis of modified 5,10:8,14-bisfragmentation cholestane derivatives
(Serbian Chemical Society, 1996)
In this paper is described a synthetic pathway to the modified 5, 10:8, 14-bisfragmentation cholestene derivatives 10, 11 and 12, which involves introduction of the Δ8(14)-double bond and 5α-hydroxyl group in the cholestane ...
Electrochemical Deposition and Phase Structure of Electrodeposited Ni-W Alloys / Elektrohemijsko taloženje i fazna struktura legura Ni-W
(Serbian Chemical Society, 1999)
The induced deposition of W in the presence of iron-group metals has been known for a long time without a proper understanding of the mechanism of codeposition. Hints were made by several authors, concerning primarily a ...
The Effect of Deposition Process Exchange Current Density on the Thin Metal Film Formation on Inert Substrate / Uticaj gustine struje izmene na proces taloženja tankih filmova metala na nesrodnim podlogama
(Belgrade : Serbian Chemical Society, 1997)
The initial stage of thin surface metal film formation on inert substrate is considered. The simultaneous action of both active centers and nucleation exclusion zones was taken into consideration when discussing the ...
Stereoselective transformation of cyclodecene-1,4-dione systems, derived from steroids, to the corresponding spiro-g-lactones. A semiempirical MO Study
(MDPI, 1999)
The thermal and acid-catalyzed intramolecular rearrangement of the (Z)- and (E)-cyclodecene-1,4-dione compounds deriving from steroids, 2a,b and 3a,b, respectively, proceeds stereoselectively to give the corresponding ...
X-Ray Analysis in the Optimization of the Sintering Process of SmCo5 Magnets
(Sintering Society, 1997)
The content of the SmCo5 phase, as the carrier of magnetic properties, was controlled by X-ray diffraction analysis. The content of the SmCo5 phase, as a function of sintering time and temperature, under constant heat ...
