(Finnish Zoological Botanical Publishing Board, 2004)Verbascum tuna-ekimii Karaveliogullari, Duran & Hamzaoglu sp. nova (sect. Bothrosperma) is described from E Anatolia in Turkey. It is related to and compared with V. laetum, from which it mainly differs in its leaves, ... -
Covalent immobilization of invertase on microporous pHEMA-GMA membrane
(Elsevier Sci Ltd, 2004)Poly (2-hydroxyethyl methacrylate-glycidyl methacrylate) (pHEMA-GMA) membrane was prepared by UV-initiated photopolymerization. Invertase was immobilized by the condensation reaction of the epoxy groups of glycidyl ... -
New syntaxa from the west part of Central Anatolia
(Pakistan Botanical Soc, 2004)Three plant communities in Central Anatolia are named, classified and briefly described. All the associations in the study area were attached to a new suballiance: Ebeno hirsutae-Thymenion leucostomi in the alliance ... -
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 ... -
Poly(styrene-hydroxyethyl methacrylate) monodisperse microspheres as specific sorbent in dye affinity adsorption of albumin
(Taylor & Francis Inc, 2004)In this study, human serum albumin (HSA) adsorption properties of reactive green HE-4BD-attached monodisperse poly(styrene-2-hydroxyethyl methacrylate) [poly(St-HEMA)] microspheres were investigated. Poly(St-HEMA) microspheres ... -
The chordae tendineae of the heart in chicken
(Blackwell Verlag Gmbh, 2004)In this study, the chordae tendineae of 10 adult chickens have been investigated by means of scanning electron microscopy (SEM). It has been observed that the diameter of the collagen fibrils on the left side of the heart ... -
Evaluation of lysozyme adsorptive behaviour of pHEMA-based affinity membranes related to the surface energy and its components to be used in chromatographic fields
(Elsevier, 2004)We have studied the influence of the surface energy and its components of two different dye-ligand immobilised poly(hydroxyethylmethacrylate) (pHEMA) membranes to the adsorption of a protein "lysozyme" from aqueous solutions. ... -
