Preparation of sedimentary organic matter concentrates by microbiological methods / Pripremanje koncentrata organske supstance primenom mikrobioloških metoda
(Acta biologica iugoslavica - serija B: Mikrobiologija, 2006)
Investigation on combined bacterial demineralization of sediments i.e. removal of silicates (desilicification) by Bacillus circulans and removal of pyrite (depyritization) by Acidithiobacillus ferrooxidans are reviewed in ...
The chemical characteristics of soil which determine phosphorus partitioning in highly calcareous soils / Hemijske karakteristike visoko-krečnjačkih zemljišta koje određuju raspodelu fosfora
(Serbian Chemical Society, 2006)
Phosphorus fractions from three highly calcareous soils (average, 24.9 ± 4.8 %CO3 2-) from sampling sites with a Mediterranean climate were isolated by sequential extraction. In order to provide a more reliable basis for ...

(Belgrade : Serbian Chamber of Commerce, Board of Environmental Protection and Sustainable Development, 2006)
The paper presents the results of ex-situ bioremediation of soil on a pilot heap (halde) within the grounds of Petroleum Refinery Pančevo, Serbia.
The influence of acid treatment on the composition of bentonite
(USA : The Clay Minerals Society, 2006)
Bentonite from the 'Bogovina' coal mine in Serbia, was characterized. The influence of acid treatment on its composition, as well as mathematical descriptions of this influence are reported. The purpose of this work was ...
Efficiency of comercial enzymatic preparations in grain hydrolyses for preparation of substrates for alcoholic fermentation
(European association for chemical and molecular sciences (EuCheMS), 2006)
In this study, we investigated the optimal composition of substrates and tested optimal enzyme concentration for most efficient substrate degradation.
Ring closing metathesis/fragmentation route to (Z)-configured medium ring cycloalkenes. Total synthesis of (+/-)-periplanone C
(American Chemical Society (ACS), 2006)
The combination of ring closing metathesis and beta-fragmentation offers an efficient entry into (Z)-configured medium ring cycloalkenes. The fragmentation step can be effected under anionic or radical conditions. The ...
The corrosion protection of the facilities in the system for milk ties pasteurization / Zaštita opreme od korozije u sistemu za pasterizaciju mleka
(Prehrambena industrija - mleko i mlečni proizvodi, 2006)
In the course of the pasteurization treatment of milk and dairy products the temperature of the technological process is kept at a constant value. The regulation of the temperature is carried out by means of technological ...
Pulse and direct current plating of Ni-W alloys from ammonia-citrate electrolyte
(Elsevier, 2006)
The effect of the potential of deposition and electrode rotation rate on current efficiency and partial current density of nickel deposition from ammonia-citrate electrolyte with and without tungstate ions was investigated. ...
