Retinal nerve fiber layer thickness in congenital color vision deficiency
(Sage Publications Ltd, 2008)
PURPOSE. To evaluate the thickness of the retinal nerve fiber layer (RNFL) in subjects with congenital red-green color vision deficiency (CVD). METHODS. This study included 20 healthy subjects with congenital red-green CVD ...
Spherical albedo problem for isotropic scattering
(Carl Hanser Verlag, 2008)
The pseudo-slab problem by using the H-N method, proper neutron flux definitions and physical boundary conditions is used to study spherical albedo. The selected numerical values can be compared with data available in the ...
In-vitro studies of enteric coated diclofenac sodium-carboxymethylcellulose microspheres
(Taylor & Francis Ltd, 1996)
Microspheres containing diclofenac sodium (DS) were prepared using carboxymethylcellulose (CMC) as the main support material (1.0, 2.0, 3.0% (w/v)) and aluminium chloride as the crosslinker. Drug to polymer ratios of 1:1, ...
Application of the dynamic stiffness technique to the in-plane vibrations of plate structures
(Pergamon-Elsevier Science Ltd, 1996)
In this study the dynamic stiffness technique, which yields ''exact'' results for a certain class of plate structure, is extended to include in-plane vibrations. Using the equations of motion and edge tractions the stiffness ...
Selectivity and kinetics of ligand exchange of anions in a chelate ion exchanger
(Gauthier-Villars, 1997)
Ligand selectivity plots and interdiffusion coefficients are presented for the chloride form of a ligand exchanger chemically derived from sporopollenin. Exchanges of iodide and bromide for chloride as the ligand were ...
[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 ...
