Selenium content and distribution in rat tissues irradiated with gamma rays
(Heidelberg : Springer, 1992)
The effects of supplementation with selenous yeast and ionizing radiation on selenium (Se) content and distribution were evaluated in rat tissues (liver, kidney, spleen, heart, muscle, blood, front brain, hind brain, ...
Oxygen reduction on single crystal platinum electrodes in phosphoric acid solutions / Redukcija kiseonika na monokristalnim platinskim elektrodama u rastvorima fosforne kiseline
(Belgrade : Serbian Chemical Society, 1999)
Oxygen reduction reaction has been studied on Pt low index planes in 0.1 M and 85% H3PO4 using hanging meniscus rotating disc electrode technique. The first-order kinetics of O2 reduction reaction was found for all three ...
Single-particle settling velocity through liquid fluidized beds
(Elsevier, 1991)
Single-particle settling velocities through waterfluidized
beds have been studied experimentally using
a standard fluidtzation column 40 mm in diameter.
All the particles used were spherical. The combinations
of ...
Oxidative processes during heat treatment in intermetallic SmCo5 powder / Oksidacioni procesi pri zagrevanju praha intermetalnog jedinjenja SmCo5
(Belgrade : Serbian Chemical Society / Beograd : Srpsko hemijsko društvo, 1996)
Understanding of the thermal stability of intermetallic SmCo5 powder is essential for designing the working atmosphere in all phases of the technological procedure in the production of sintered SmCo5 magnets to obtain ...
Photodiode quantum efficiency optimization using spherical pits on active surfaces
(Elsevier, 1995)
A numerical model of a photodiode with etched spherical pits on an active surface has been developed. Several geometrical parameters (radius of curvature, depth and arrangement of spherical pits, sample thickness and area, ...
Identification of intermetallic compounds in thin layers of electrodeposited Cu–Cd alloys using electrochemical techniques
(USA :Taylor & Francis INC, 1991)
An attempt was made to analyse the phase structure of thin layers of electrodeposited Cu–Cd alloys using anodic linear sweep voltammetry combined with a potentiostatic pulse technique (ALSV–PPT). The results were compared ...

Sesquiterpene lactones from Achillea crithmifolia
(Elsevier, 1991)
The isolation of guaianolides rupicolin-A, rupicolin-B, their acetates and a new germacranolide 1β,10α-epoxy-3β,9β-diacetoxy-11α,13-dihydrocostunolide, identified by means of PS DQF COSY and PS NOESY, from Achillea ...
The kinetics of the reduction of the lipophilic quinone avarone by n-alkyl-1,4-dihydronicotinamides of various lipophilicities / Kinetika redukcije lipofilnog hinona avarona n-alkyl-1,4-di -hidronikotinamidima različite lipofilnosti
(Belgrade : Serbian Chemical Society, 1999)
Several NADH model compounds, N-alkyl-1,4-dihydronicotinamides, some of them possessing amphiphilic properties, have been synthesized, and the kinetics of their reaction with a biologically active liphophilic quinone, ...
Evaluation of the effects of native minerals on the organic matter of Aleksinac oil shale based on the composition of free and bound bitumens
(Organic Geochemistry, 1992)
In order to evaluate the adsorption and catalytic effects of indigenous carbonates and silicates on the organic matter of Aleksinac oil shale, the free and the bound bitumens were isolated and analyzed by organic geochemical ...
