Affinity membrane chromatography: relationship of dye-ligand type to surface polarity and their effect on lysozyme separation and purification
(Elsevier, 2004)
Two different dye-ligands, i.e. Procion Brown MX-5BR (RB-10) and Procion Green H-4G (RG-5) were immobilised onto poly(2-hydroxyethylmethacrylate) (pHEMA) membranes. The polarities of the affinity membranes were determined ...
Characterisation of tyrosinase immobilised onto spacer-arm attached glycidyl methacrylate-based reactive microbeads
(Elsevier Sci Ltd, 2004)
Immobilisation of tyrosinase onto modified poly(methyl methacrylate-glycidyl methacrylate-divinyl benzene), poly(MMA-GMA-DVB), microbeads was studied. The epoxy group containing poly(MMA-MMA-DVB) microbeads were prepared ...
Preparation and application of spacer-arm-attached poly (hydroxyethyl methacrylate-co-glycidyl methacrylate) films for urease immobilisation
(Elsevier Science Bv, 2003)
Immobilisation of urease onto plain and six-carbon spacer-arm (i.e. 1,6-diaminohexane) attached poly(hydroxyethyl methacrylate-co-glycidyl methacrylate) [poly (HEMA-GMA)] films was studied. The epoxy groups containing ...
Fluoride release from microporous poly(2-hydroxyethyl methacrylate) membranes
(Elsevier Science Bv, 2003)
Fluoride ion is commonly used in the preventive treatment of tooth decay and when provided with extra fluoride, children living in regions that lack fluoride benefit from it. In the present study, the clinical properties ...
Polyhydroxyethylmethacrylate/polyhydroxybutyrate composite membranes for fluoride release
(Wiley, 2003)
Controlled release technology is a recent technology which has considerable potential in the fields of medicine, pharmacy, and agriculture. Fluoride ion is commonly used in the preventive treatment of decay, and when ...

Astragalus hamzaoglui O. Ketenoglu & Y. Menemen (Fabaceae), a new species from Turkey is described and illustrated. It belongs to section Hypoglottoidei DC. and resembles A. viciifolius DC. and A. viridissimus Freyn & ...
Astragalus hamzae (Fabaceae), a new species from Central Anatolia, Turkey
(Finnish Zoological Botanical Publishing Board, 2003)
Astragalus hamzae E. Hamzaoglu from Central Anatolia (Kirikkale-Turkey) is described as a species new to science and illustrated. It belongs in the section Caprini DC. and is related to A. pinetorum. Boiss., from which it ...
Procion Green H-4G immobilized poly(hydroxyethylmethacrylate/chitosan) composite membranes for heavy metal removal
(Elsevier Science Bv, 2003)
The effective removal of toxic heavy metals from environmental samples still remains a major topic of present research. Metal-chelating membranes are very promising materials as adsorbents when compared with conventional ...
Restoration of the eutrophic Lake Eymir, Turkey, by biomanipulation after a major external nutrient control I
(Springer, 2003)
Nutrient loading in lakes is recognized as a serious threat to water quality. Over 25 years of raw sewage effluent discharge shifted Lake Eymir from a state dominated by submerged plants to a turbid water state. Successful ...
Covalent immobilisation of invertase onto a reactive film composed of 2-hydroxyethyl methacrylate and glycidyl methacrylate: properties and application in a continuous flow system
(Elsevier Science Sa, 2003)
Invertase was covalently immobilised on the poly(hydroxyethyl methacrylate-co-glycidyl methacrylate) (poly(HEMA-GMA)) film. The invertase immobilisation capacity of the films was increased as the GMA ratio increased in the ...
