Current state and perspectives of fresh water fishery in Serbia / Stanje i perspektive razvoja slatkovodnog ribarstva u Srbiji
(Naučno društvo agrarnih ekonomista Balkana, Beograd, Institut za ekonomiku poljoprivrede, Beograd i Akademija ekonomskih nauka, Bukurešt, 1994)
The observed misbalance between fisheries production and consumption in Serbia, has caused rapidly increasing prices. Production growth in lowland carp ponds, will be the most adequate, because there is no sufficient natural ...
Simultaneous electrolytic production of xylitol and xylonic acid from xylose
(Journal of Applied Electrochemistry, 1991)
A new electrocatalytic process for simultaneous electrolytic production of xylitol and xylonic acid or the corresponding xylonate salts directly from α-d-xylose in alkaline solutions of neutral salt as supporting electrolyte ...
Comparison of binary gas mixture separations in single-membrane and two-membrane cascades
(Hungarian Journal of Industrial Chemistry, 1998)
The objective of this paper is to develop material balances, equilibrium, and transport equations for a binary gas mixture separation in the single-membrane and two-membrane cascades, and to compare their performances. An ...
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 ...
Monoterpenoids from Helminthia echoides
(Fitoterapia, 1998)
Biochemical and histopathological effects of glyphosate on carp, Cyprinus carpio L.
(Bulletin of Environmental Contamination and Toxicology, 1996)
Principal maize viruses in Mediterranean countries
(Agronomie, 1995)
Maize plants with virus-like symptoms were sampled in fields in Greece, Yugoslavia and Italy in 1994. Disease incidence (%) and disease severity (1-6) were assessed. Leaf samples were tested by enzyme-linked immunosorbent ...
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 ...
