[N,N '-bis(5-bromosalicylidene)-1,3-diaminopropane]copper(II)
(Munksgaard Int Publ Ltd, 1999)
The title compound, [Cu(C17H14Br2N2O2)], has a crystallographic twofold axis. The coordination geometry about the Cu-II centre is a tetrahedrally distorted square plane formed by the four-coordinate N2O2 donor set of the ...
Characterization of β-galactosidase immobilized into poly(hydroxyethylmethacrylate) membranes
(Mbr Press Inc, 1998)
beta-galactosidase was immobilized into pHEMA membranes with the highest specific activity yield of 9.5%. The specific activity of the entrapped enzyme was found to be decreased as the enzyme loading increased in pHEMA ...
Affinity microspheres and their application to lysozyme adsorption: Cibacron Blue F3GA and Cu(II) with poly(HEMA-EGDMA)
(Wiley, 1999)
Lysozyme adsorption onto Cibacron Blue F3GA attached and Cu(II) incorporated poly(2-hydroxyethyl methacrylate-ethylene glycol dimethacrylate) [poly(HEMA-EGDMA)] microspheres was investigated. The microspheres were prepared ...
Diffusion and selective transport of alkali cations in a polysulfone ion exchange membrane
(Gauthier-Villars, 1995)
he diffusion of alkali metals through a charged polysulfonated ICE-450 ion exchange membrane has been measured as a function of pH and conservation of the external solution at 25 degrees C. The permeability and diffusion ...
N-(p-chlorophenyl)-3,3-diphenyl-4-(β-phenylstyryl)azetidin-2-one
(Munksgaard Int Publ Ltd, 2000)
In the title compound, C35H26ClNO, the four-membered beta-lactam ring is essentially planar, with a maximum deviation of 0.012 (1) Angstrom for the N atom. The C-C bond lengths in the beta-lactam ring are 1.591 (2) and ...
A study of egg production in three species of wolf spiders (Araneae, Lycosidae), Pardosa amentata, P-palustris, and P-pullata in the field
(Laser Pages Publ Ltd, 2000)
Egg production by three species of Pardosa was studied over a 3-year period in a grassland, a fallow field, and a meadow in Northumberland (England). Differences in egg production were found to be related to the size of ...
The effects of the time-dependent and exposure time to air on Au epilayer n-Si Schottky diodes
(E D P Sciences, 1999)
A study on Au/n-Si Schottky barrier diodes (SBDs) parameters with and without thin native oxide layer fabricated on n-type Si grown by LPE (Liquid-Phase Epitaxy) technique has been made. The native oxide layer with different ...
Comparison of the heavy metal biosorption capacity of active, heat-inactivated and NaOH-treated phanerochaete chrysosporium biosorbents
(Wiley, 2004)
Three different kinds of Phanerochaete chrysosporium (NaOH-treated, heat-inactivated and active) biosorbent were used for the removal of Cd(II) and Hg(II) ions from aquatic systems. The biosorption of Cd(II) and Hg(II) ...
Controlled release of insecticide carbaryl from crosslinked carboxymethylcellulose beads
(Parlar Scientific Publications (P S P), 2004)
Copper-carboxymethylcellulose (CuCMC) beads containing carbaryl were prepared by the ionotropic crosslinking of sodium carboxymethylcellulose (NaCMC) with copper ions. The beads were characterized by carbaryl encapsulation ...
Subspaces of A-statistically convergent sequences
(Akademiai Kiado, 2003)
Let A be a nonnegative regular summability method. In this paper we deal with various subspaces of A-statistically convergent sequences by using the rate of convergence concept. We show, under certain conditions, that these ...
