Classification of the asphalts and their source rock from the Dead Sea Basin (Israel): the asphaltene/kerogen vanadyl porphyrins
(Journal of the Serbian Chemical Society, 1998)
The asphaltenes of the asphalts from the Dead Sea Basin were examined for the presence of vanadyl porphyrins. These examinations demonstrated that the asphalts fall into two broad class types, one having a relatively high ...
The effect of rapid thermal annealing on structural and electrical properties of TiB2 thin films
(Thin Solid Films, 1997)
This work reports on the effect of post-deposition rapid thermal annealing on the structural and electrical properties of deposited TiB2 thin films. The TiB2 thin films, thicknesses from 9 to 450 nm, were deposited by ...

The synthesis and crystal structure of the title compound, K+. C5H9N2O2S2-. 2H(2)O, are described. The structure consists of potassium cations, 3-dithiocarboxy-3-aza-5-aminopentanoate anions and molecules of water. The ...
Model of improved arc generator for fullerene production
(Fullerene Science and Technology, 1997)
Process of fullerene formation and fragmentation is studied in various zones of fullerene generator. Fullerenes are produced utilizing carbon are method, in which graphite electrodes are vaporized in a low pressure helium ...
Kinetics of fullerene formation in a contact arc generator
(Fullerene Science and Technology, 1998)
It kinetic model of the fullerene growth process in a contact are generator is developed. On the basis of the kinetic model, the yield of the magic fullerenes C-60 and C-70 is calculated. The fullerene yield is determined ...
Kinetic model of metallofullerene formation in contact arc generator
(Fullerene Science and Technology, 1999)
A kinetic model of the metallofullerene growth process in a contact are generator is developed. The metals chosen for the kinetic analysis were lanthan and calcium. An optimum starting composition of composite electrode ...
Apo B3 Hvr Polymorphism in Healthy Population: Relationships to Serum Lipid Levels
(Genetic Epidemiology, 1998)
We have analyzed allele frequency distribution at the hypervariable locus 3 to the apolipoprotein B gene in a healthy population sample (241 women and 246 men) from the Belgrade area. The bimodal distribution of sixteen ...
Prevention and recovery of CuSO4-induced inhibition of Na+/K+-ATPase and Mg2+-ATPase in rat brain synaptosomes by EDTA
(Toxicology Letters, 1999)
Enzymatic activities of Na+/K+-ATPase and Mg2+-ATPase from rat brain synaptic plasma membrane were studied in the absence and presence of EDTA. The aim of the study was to examine the ability of this strong chelator to ...
