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

The biodegradation of wheat straw by Pleurotus ostreatus mushrooms and its use in cattle feeding
(Elsevier, Amsterdam, 1998)
The influence of Pleurotus ostreatus enzymes on wheat straw degradation was investigated in laboratory conditions. Chopped and pressure-pasteurized straw with 24% dry matter was seeded with mushroom mycelium. Analyses of ...
Discrimination between some Chinese and Yugoslav winter wheat cultivars by capillary electrophoresis of gliadins
(Seed Science and Technology, 1998)
Gliadin proteins extracted from seventeen China and Yugoslav winter wheat cultivars were separated by capillary electrophoresis (CE). In order to optimise resolution and reproducibility of gliadin separations, different ...
Potentiometric titration of pralidoxime chloride (2-pyridinealdoxime methochloride) with a silver indicator electrode
(Journal of Analytical Chemistry, 1998)
It is shown that a silver indicator electrode can be used in the potentiometric titration of pralidoxime chloride [2-pyridinealdoxime methochloride (PAM-2)] with palladium(II) chloride and silver nitrate solutions. The ...
Observations on spear replacement in Xiphinema dentatum (Nematoda : Longidoridae)
(Brill Academic Publishers, Leiden, 1998)
The process of spear (odontostyle + odontophore) replacement was determined by studying juveniles of Xiphinema dentatum in different phases of moulting. The process is subdivided into eight distinct phases, each readily ...
A preconditioning process for extended passivation of alloyed lead anodes in zinc electrowinning
(Central Electrochem Res Inst, Karaikkudi, 1998)
On the basis of an old Cominco, Trail. B.C., idea of preconditioning silver (0.8 wt%) alloyed lead electrodes for a proper passivation, optimal, chemically balanced and more economical process has been developed for use ...
Description of three populations of Xiphinema dentatum Sturhan, 1978 from Yugoslavia and observations on X-turcicum Luc & Dalmasso, 1964 (Nematoda : Longidoridae)
(Fundamental and Applied Nematology, 1998)
Three populations of X. dentatum originating from a mountainous region of Yugoslavia are described. The morphological and biometrical characteristics are studied and compared with those of other previously described ...
