CO interaction with zeolites studied by TPD and FTIR: transition-metal ion-exchanged FAU-type zeolites
(Elsevier, Amsterdam, 1999)
The interaction of carbon monoxide with the cationic Lewis acid sites of transition-metal (Fe2+, Co2+, Ni2+) and Cu2+-exchanged Y and X zeolites was investigated by Fourier transform infrared spectroscopy (FTIR) and ...
Pathogenic and bacteriological characteristics of Yugoslav Erwinia soft rot strains originating from pepper and eggplant fruits
(Zeitschrift fur Pflanzenkrankheiten und Pflanzenschutz, 1997)
Eight bacterial isolates from pepper and eggplant fruits showing soft rot symptoms were investigated The strains showed a uniform reaction for most of the pathogenic and biochemical tests, with a few exceptions. Differences ...
Biochemical and histopathological effects of glyphosate on carp, Cyprinus carpio L.

13C N.M.R. spectra of some 5-substituted-3-isopropyl-6-methyl uracils
(Journal of Molecular Structure, 1990)
13C n.m.r. spectra of some 5-substituted-3-isopropyl-6-methyl uracils were determined in deuterated dimethyl sulfoxide (d6 - DMSO). The substituents are : H, Cl, Br, J, NO2, NH2, N(CH3)2, C6H5, C6H4-NO2-p and C6H4-NH2-p. ...
Factors influencing alcohol and extract separation in beer dialysis
(World Journal of Microbiology & Biotechnology, 1995)
An 8-μm thick Cuprophane hollow-fibre membrane not only had a higher ultrafiltration coefficient than an 11-μm thick membrane but was more permeable and selective for ethanol dialysis and extract removal from beer. ...
Design of land-air parameterization scheme (LAPS) for modelling boundary layer surface processes
(Springer Wien, Wien, 1996)
A land-air parametrization scheme (LAPS) describes mass, energy and momentum transfer between the land surface and the atmosphere. The scheme is designed as a software package which can be run as part of an atmospheric ...
Influence of beer flow rate on mass transfer kinetics in beer dialysis
(Biotechnology Techniques, 1993)
The basic parameters for mass transfer of alcohol and extract have been determined. The beer flow rate influences both efficiency and selectivity of the alcohol separation. The results suggest that, in order to achieve a ...
Acute and subacute toxicity of atrazine to carp (Cyprinus carpio L.)
(Ecotoxicology and Environmental Safety, 1993)
Investigations of acute and subacute atrazine toxicity in carp (Cyprinus carpio L.) were carried out. Acute toxicity was investigated in a semi-static test during a 96-hr exposition. The estimated LC-50 value was 18.8 mg/l. ...

Effects of excessive levels of sodium selenite on daily weight gain, mortality and plasma selenium concentration in chickens
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 1999)
One hundred and five, one day old unsexed Hybro chickens divided into 7 groups, were fed basal diets supplemented with 0, 2, 5, 10, 20 and 30 mg Se/kg as sodium selenite for 6 weeks. The Se level of 2 mg/kg feed had no ...
