Theoretical investigation of the adsorption of a binary mixture in a chromatographic column using the nonlinear frequency response technique
(Springer, New York, 2007)
The nonlinear frequency response of a chromatographic column for the adsorption of two dissolved components is analyzed using the concept of higher order frequency response functions (FRFs) which is based on the Volterra ...
Characteristics of natural isolates of lactic acid bacteria selected for construction of starter cultures for semi-hard cheese of the Trapist type
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 2001)
Starter cultures (S12, S19 and S21) for semi-hard cheese of the Trapist type were constructed by using natural isolates of lactic acid bacteria (LAB) that were mostly isolated from home-made cheese. These starter cultures ...
Benzylation of N-phenyl-2-phenylacetamide under microwave irradiation / Benzilovanje N-fenil-2-fenilacetamida pomoću mikrotalasnog zračenja
(Serbian Chemical Society, Belgrade, 2008)
N-Phenyl-2-phenylacetamide was alkylated with benzyl chloride in the presence of powdered potassium hydroxide under microwave irradiation in a solvent-free system. The reactions were also performed in the presence of ...
Mass transfer between a fluid and an immersed object in liquid-solid packed and fluidized beds / Prenos mase fluid-uronjeni objekat u pakovanim i fluidizovanim slojevima tečnost-čestice
(Serbian Chemical Society, Belgrade, 2005)
The mass transfer coefficient between fluid and an immersed sphere in liquid packed and fluidized beds of inert spherical particles have been studied experimentally using a column 40 mm in diameter. The mass transfer data ...
