Design of land-air parameterization scheme (LAPS) for modelling boundary layer surface processes
(Springer Wien, Wien, 1996)
A land-air parametrization scheme (LAPS) describes mass, energy and momentum transfer between the land surface and the atmosphere. The scheme is designed as a software package which can be run as part of an atmospheric ...
Toxic effects of 2,4-D herbicide on fish
(Journal of Environmental Science and Health - Part B Pesticides, Food Contaminants, and Agricultural, 1994)
Acute and subacute 2,4-D toxicity to carp (Cyprinus carpio L.) were investigated. Acute toxicity (LC-50) was investigated in semi-static test during a 24, 48 and 96- hours exposition. Subacute toxicity was investigated by ...
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. ...
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 ...
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 ...
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)
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 ...
