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 ...

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 ...
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. ...
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 ...
Application of the critical path method (CPM) in organizing peach planting / Primena mrežnog planiranja u organizaciji podizanja dugogodišnjih zasada breskve
(Naučno društvo agrarnih ekonomista Balkana, Beograd, Institut za ekonomiku poljoprivrede, Beograd i Akademija ekonomskih nauka, Bukurešt, 1994)
The CPM method, presented in this study, has been applied in the model organization for peach planting. In order to make planning of resources (labor and means) and organization itself easier, time reserves pointing to the ...
