Electrocatalysis for hydrogen electrode reactions in the light of Fermi dynamics and structural bonding factors - I. Individual electrocatalytic properties of transition metals
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
The Brewer valence-bond theory for bonding in metals and intermetallic phases has been employed, together with Fermi dynamics, to correlate with the electrocatalytic properties of both individual and composite transition ...
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 ...
Genetic resources of cherry plum (Prunus cerasifera ehrh.)
(Acta Horticulturae, 1998)
Investigations were carried out on 63 cherry plum genotypes collected from different autochthonous populations in Serbia. Morphological and biochemical variability of these genotypes was analyzed by multivariate analysis ...
Properties of late-ripening peach hybrids
(Acta Horticulturae, 1998)
From the progeny obtained by open-pollination of J. H. Hale cultivar, five midle late or late ripening hybrids were selected. During 1995 and 1996 important pomological properties of those hybrids were examined. Based on ...
Functional enzymes activity and gill histology of carp after copper sulfate exposure and recovery
(Academic Press Inc Elsevier Science, San Diego, 1998)
Copper sulfate is one of the most widely used algicides for the control of phytoplankton in lakes, reservoirs, and ponds. It is also used for aquatic weed control. To study the toxic effects of copper on carp (Cyprinus ...
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)
Fire blight of pear in Yugoslavia
(Acta Horticulturae, 1998)
Fire blight of pear, caused by Erwinia amylovora (Burr.) Winslow, et al., is one of the oldest and the most destructive disease caused by bacteria on pome fruits. This disease is most dangerous on pear (Pyrus sp.), making ...
