Cancer Incidence in a Population Living Near a Petrochemical Facility and Oil Refinery
(Collegium Antropologicum, Zagreb, 2011)
There is growing concern that pollution from petrochemical and oil refinery installations in Pancevo (Serbia) has increased the incidence of various diseases including cancer The aim of our study was to investigate cancer ...
Effect of Candida antarctica Lipase B Immobilization on the Porous Structure of the Carrier
(Wiley-V C H Verlag Gmbh, Weinheim, 2011)
A series of poly(GMA-co-EGDMA) resins with identical composition but varying particle sizes, pore radii, specific surface areas and specific volumes are studied to assess how Candida antarctica lipase B immobilization ...
Determination of critical conditions for the formation of electrodeposited copper structures suitable for electrodes in electrochemical devices
(MDPI, 2007)
Electrodeposition of copper from acid sulfate solutions at overpotentials on the plateau of the limiting diffusion current density and at higher overpotentials was examined. The average current efficiencies for hydrogen ...
Defensive Secretions in Three Species of Polydesmids (Diplopoda, Polydesmida, Polydesmidae)
(Springer, Dordrecht, 2010)
Nine compounds were detected in three different millipede species: Polydesmus complanatus (L.), Brachydesmus (Stylobrachydesmus) avalae A dagger uriA double dagger & Makarov, and Brachydesmus (Stylobrachydesmus) dadayi ...
Effect of codeposition of polymer on the morphology of electrodeposited copper
(Kluwer Academic Publishers, 1979)
Poly(4-vinyl pyridine-co-methyl methacrylate), which is soluble in water in its protonated form and insoluble as a neutral molecule, has been synthesized and introduced into an acid bath for copper deposition. Potential-sweep ...
Photodegradation of thiacloprid using Fe/TiO2 as a heterogeneous photo-Fenton catalyst
(Elsevier, 2011)
Three Fe/TiO2 photocatalysts with different content of Fe (1.9, 7.2 and 13.9%, w/w) were synthesized by a simple deposition-precipitation method and characterized by XRD, SEM, N-2 physisorption at 77K and Mossbauer ...
Electrocatalysis of oxygen on single crystal gold electrodes
(Elsevier, 1989)
Oxide formation and oxygen reduction on gold have been investigated with single crystal electrode surfaces of various orientations. Both reactions show sensitivity to the surface orientation, presence of steps, their density ...
Meaning and application of intelligent sensors / Značenje i primena inteligentnih senzora
(Tehnika - Mašinstvo, 2010)
In this work is defined by the sensor. It is made the division of the sensors and their application. Technology development is very complex. Without the use of sensors is impossible to perform the simplest activities. The ...
Remote functionalisation by ferrous ion-cupric ion induced decomposition of alkyl hydroperoxides
(Pergamon Press, 1979)
By decomposition of alkyl hydroperoxides 1-8 with ferrous sulfate-cupric acetate reagent, intramolecular functionalisation of remote non-activated C atom takes place and unsaturated alcohols with double bond mainly at ...
Phytochemicals from bryophytes: Structures and biological activity / Фитохемикалије из бриофита: структура и биолошке активности
(Serbian Chemical Society, 2021)
Little attention has been paid to the bryophytes as sources for human diet despite the presence of 23,000 species in the world. Some mosses contain Vitamin B1, tocopherols, prostaglandin-like highly unsaturated fatty acids ...
