Binary gas mixture separation in dual, permeators with permeate recycles
(Hungarian Journal of Industrial Chemistry, 1998)
Mathematical models of perfectly mixed dual permeators with permeate recycles, operating with zero reject flow rate and zero permeate pressures (gamma' = gamma " = 0), have been developed. The equations for determination ...
Antimicrobial activity of essential oil of Carlina acaulis L., Asteraceae
(Pharmaceutical and Pharmacological Letters, 1998)
Diffusion techniques on Mueller - Hinton agar as well as dilution technique in Mueller - Hinton broth were applied to test sensitivity of certain bacteria to Carlina acaulis L. root essential oil. Saburaud base was used ...

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. ...
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. ...
A case of monstra duplicia in Tetranychus urticaekoch (Acari: Tetranychidae)
(Acarologia, 2000)
A case of monstra duplicia is recorded in a laboratory population of Tetranychus urticae Koch. The population had not been previously exposed to teratogenic agents. The developmental abnormality was found in the protonymph ...
Sugarcane mosaic virus - An important pathogen on maize in Yugoslavia

Peroxidase isoenzymes in strawberry roots infected with binucleate Rhizoctonia spp. and their implication in disease resistance
(Wiley, Hoboken, 1997)
Infection of strawberry plants with binucleate Rhizoctonia spp. results in an increase in peroxidase activity and the appearance of new isoforms of the enzyme. In healthy and diseased roots of two different strawberry ...
