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 ...
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 ...
Ar I and Ne I spectral line shapes for an abnormal glow discharge diagnostics
(IOP Publishing Ltd, Bristol, 2013)
We report the results of an Ar I and Ne I line shape study in an abnormal glow discharge operating in argon and neon. The spectral lines were observed along the axis of a cylindrical glow discharge parallel (side-on) and ...
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 ...
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 ...
Comparison of possible phytotoxic metabolites in culture filtrates of the Diaporthe/Phomopsis complex of soybeans
(Mycopathologia, 1989)
Filter-sterile culture filtrates of isolates of Diaporthe phaseolorum var. caulivora, Diaporthe phaseolorum var. sojae (anamorph Phomopsis sojae), and Phomopsis longicolla, causal agents of stem canker, pod and stem blight, ...
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. ...
Simultaneous electrolytic production of xylitol and xylonic acid from xylose
(Journal of Applied Electrochemistry, 1991)
A new electrocatalytic process for simultaneous electrolytic production of xylitol and xylonic acid or the corresponding xylonate salts directly from α-d-xylose in alkaline solutions of neutral salt as supporting electrolyte ...
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 ...
