Copper-deposited wire ion-selective electrode for the determination of copper(II)
(The Analyst, 1987)
A wire ion-selective electrode was made by sulphiding electrolytic copper previously deposited on commercial copper wire. Sulphidation was carried out by means of gaseous hydrogen sulphide at an increased temperature. The ...
Coupled vertical mast (monopole) antennas in the presence of a conducting half-space
(Ieee-Inst Electrical Electronics Engineers Inc, Piscataway, 1998)
The unknown current distribution (UCD), self and mutual admittances (impedances), grounding impedances of coupled vertical mast antennas (CVMA) on a conducting halfspace are presented in this paper. The UCD is determined ...
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 ...
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 ...
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 ...
The preferred orientation of bright copper deposits
(Trans Tech Publications Ltd, Durnten-Zurich, 2000)
The preferred orientations of copper deposits obtained from acid sulfate solutions were examined. Mat deposits obtained in the absence of the additives and in the presence of disodium 2-naphthol-3,6-disulfonic acid possessed ...
Thermal effects of the interactions of carbon monoxide with zeolites
(Elsevier, Amsterdam, 2001)
The interactions of carbon monoxide with Lewis acid sites of zeolites were investigated using microcalorimetric and temperature programmed desorption (TPD) techniques. Carbon monoxide was adsorbed at 25 degreesC on ...
Continuous cider fermentation with co-immobilized yeast and Leuconostoc oenos cells
(Elsevier Science Inc, New York, 2000)
Ca-alginate matrix was used to co-immobilize Saccharomyces bayanus and Leuconostoc oenos in one integrated biocatalytic system in order to perform simultaneously alcoholic and male-lactic fermentation of apple juice to ...
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 ...
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 ...
