Immobilization of yeast cells in small alginate beads using electrostatic droplet generation / Primena postupka elektrostatičke ekstruzije pri dobijanju alginatnih čestica malih dimenzija sa imobilisanim ćelijama pivskog kvasca
(Faculty of Technology, Novi Sad, 2000)
In beer brewing with immobilized yeast cells it is very important to minimize the mass transfer resistance, problem associated with large diameter beads, because the mass transfer limitations may force the cells to alter ...
Conformation of N-substituted 2-phenylbutanamides / Konformacije N-supstituisanih 2-fenilbutanamida
(Univerzitet u Nišu, Niš, 2000)
Various N-substituted 2-phenylbutanamides, CH3CH2CH(Ph)CONHR, where R is ethyl, n-butyl, i-butyl, cyclohexyl and phenyl, were synthesized. They were characterized by m.p., FT-IR, 1H NMR and mass spectra. Depending on the ...
Have you ever thought about mole and its place in the international system of units? / Da li ste ikada razmišljali o molu i njegovom mestu u međunarodnom sistemu jedinica?
(Srpsko hemijsko društvo, Beograd, 2000)
A short historical review of measuring and units has been given in the first part of this paper. The most attention has been paid to the decimal metric system and to the development of International system of units (SI). ...
Identification and characterization of natural lactic microflora of home made white cheese from Sjenica / Identifikacija i karakterizacija prirodnih izolata bakterija mlečne kiseline iz sjeničkog sira
(Savez poljoprivrednih inženjera i tehničara, Beograd, 2000)
A total of 160 isolates of lactic acid bacteria (LAB) were obtained from samples taken at various stages of the manufacture and ripening (nine months) of home made white cheese from Sjenica (a traditional raw mixed cow's ...
Formic acid oxidation on pure and Bi-modified Pt(111): Temperature effects
(Amer Chemical Soc, Washington, 2000)
Temperature effects on the kinetics of formic acid electrooxidation are studied on Pt(111) and on Pt(111) modified by irreversibly adsorbed Bi under both potentiodynamic and potentiostatic conditions. We propose two modes ...
Effects of substituents on the electronic absorption spectra of 3-N-(4-substituted phenyl)-5-carboxy uracils in different solvents: Part II / Efekat supstituenata na apsorpcione spektre 3-N-(4-supstituisanih fenil)-5-karboksi uracila u različitim rastvaračima - deo II
(Serbian Chemical Society, Belgrade, 2000)
Absorption spectra of some 3-N-(4-substituted phenyl)-5-carboxy uracils, previously determined in twelve solvents, are correlated with substituent sp+ values or by dual substituent parameter correlations involving sI and ...
Immobilization/encapsulation of cells using electrostatic droplet generation - Experiments and theory
(Minerva Biotecnologica, 2000)
The mechanism of alginate droplet formation as well as experimental parameters for producing very small polymer microbeads (i,e, less then 100 microns diameter) using an electrostatic droplet generator were investigated, ...
Mixed ligand Co(II), Ni(II) and Cu(II) complexes containing terephthalato ligands. Crystal structures of diaqua(2,2 '-dipyridylamine)(terephthalato)metal(II) trihydrates (metal = cobalt or nickel)
(Pergamon-Elsevier Science Ltd, Oxford, 2000)
A series of nine ternary Co(II), Ni(II) and Cu(II) complexes with some aromatic diamines and dianion of terephthalic acid (tpht) have been synthesized and characterized by elemental analysis, magnetic susceptibility ...
Study of chlorination of nickel ferrite by gaseous chlorine and calcium chloride in the presence of active additives
