Determination of Cu, Zn and Cd in water by FAAS after preconcentration by baker's yeast (Saccharomyces cerevisiae) immobilized on sepiolite
(Springer Verlag, 1999)
By using the adsorbent Saccharomyces cerevisine immobilized on sepiolite an adsorption-elution method was developed for the preconcentration of Cu, Zn, and Cd followed by flame atomic absorption spectrometry (FAAS). ...
Immobilization of glucose oxidase and urease in hydrogel matrices
(Scientific Technical Research Council Turkey, 1997)
Immobilization of glucose oxidase and urease in hydrogels of 2-hydroxyethyl methacrylae, and N-vinyl pyrrolidone (NVP) was achieved by irradiation (using UV kand gamma-rays). The effect of radiation on entrapment efficiencies, ...
Controlled release of Aldicarb from carboxymethylcellulose microcapsules
(Scientific Technical Research Council Turkey, 1997)
Sodium carboxymethyl cellulose was converted into microspheres by crosslinking with aluminum chloride. Various microsheres with different amounts of crosslinker, biopolymer of various concentrations and molecular weights, ...
Failure analysis of two-dimensional carbon-epoxy composite plate pinned joint
(Taylor & Francis Inc, 1999)
The aim of this study is to investigate failure strength and failure mode of a mechanically fastened carbon-epoxy composite plate of arbitrary orientation. The failure load and the failure mode are analyzed numerically and ...

(Munksgaard Int Publ Ltd, 1999)
The title compound, C23H26N2O2. 2H(2)O, displays strong intramolecular N-H ... O [2.637(2) Angstrom] and intermolecular O-H ... O [2.763(4) and 2.842(3) Angstrom] hydrogen bonds within each salicylideneimine unit and water ...
Biodegradation of aldicarb in a packed-bed reactor by immobilized Methylosinus
(Elsevier Science Inc, 1999)
Carboxymethylcellulose microspheres cross-linked via aluminum ions were used as a support material for immobilization of Methylosinus isolated from soil contaminated with aldicarb. The degradation capacity of immobilized ...
Controlled release of aldicarb from lignin loaded ionotropic hydrogel microspheres
(Taylor & Francis Ltd, 1999)
Aldicarb loaded microspheres of carboxymethyl cellulose, CMC, of various compositions were prepared with the crosslinking action of AI(III). Into these microspheres, lignin was introduced as a filler to further regulate ...
β-galactosidase immobilization into poly(hydroxyethyl methacrylate) membrane and performance in a continuous system
(Wiley-Blackwell, 1999)
The activity of beta-galactosidase immobilized into a poly(2-hydroxyethyl methacrylate) (pHEMA) membrane increased from 1.5 to 10.8 U/g pHEMA upon increase in enzyme loading. The K-m values for the free and the entrapped ...
Improving performance of switched reluctance motor by fuzzy logic controller
(John Wiley & Sons Ltd, 1999)
This paper presents torque ripple minimization of a switched reluctance motor (SRM) by using a fuzzy controller, The nonlinear model of the SRM and the mathematical model of the converter circuit are driven. The motor used ...
