(Versita, 2004)
Scorzoncra yildirimlii A. DURAN et HAMZAOGLU sp. nov. from southwestern Turkey is described and illustrated. It is related to S. pygmaea SIBTH. & SM. and S. rigida AUCHER, from which it mainly differs in its habitus, leaves, ...
The study of the (n,2n) reaction cross-sections for neighbor deformed nuclei in the region of rare-earth elements
(Slovak Acad Sciences Inst Physics, 2004)
The (n,2n) reaction cross-section calculations for some neighbor deformed target nuclei have been made in the region of rare-earth elements between 8 and 24 MeV incident energy. In the calculations, the geometry dependent ...
4-[(4-chlorobenzylidene)amino]phenol
(Int Union Crystallography, 2004)
In the molecular structure of the title Schiff base, C13H10ClNO, the chlorophenyl ring and formimidoyl moiety are almost coplanar, and the dihedral angle between the planes of the phenol and chlorophenyl ring is 34.57 ...

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 ...
Ring opening polymerization of 2,5-dihydro-2,5-dimethoxyfuran by electrochemical initiation
(Springer, 2004)
2,5-Dihydro-2,5-dimethoxyfuran (DHMF) was polymerized via constant current electrolysis (CCE), in CH3CN-NaClO4 solvent-electrolyte couple. Poly(DHMF) was obtained from the anolyte. The effect of current density, temperature, ...
Immobilization of a thermostable α-amylase onto reactive membranes: kinetics characterization and application to continuous starch hydrolysis
(Elsevier Sci Ltd, 2004)
Epoxy groups containing porous membranes were prepared by UV-initiated photopolymerisation of hydroxyethylmethacrylate (HEMA) and glycidyl methacrylate (GMA). Epoxy supports could provide multipoint covalent attachment of ...
The effect of nitrogen atom on double bond pyramidalization
(Springer/Plenum Publishers, 2004)
The title compound 6-phenyl-4,6,8-triazatetracyclo[9.2.1.0(2,10).0(4,8)] tetradec-2(10)-ene-5,7-dione ( 6) has been synthesized by the addition of 4-phenyl-1,2,4-triazole-3,5-dione (PTAD) to 2,3-dimethylenebicyclo[2.2.1] ...
Investigation of Al-O-Al sites in an Na-aluminosilicate glass
(Indian Academy Sciences, 2004)
This paper reports the presence of Al-O-Al linkages in an aluminosilicate glass where Si/Al = 1 by using 2D O-17 triple quantum MAS NMR technique (3Q MASNMR). The experiments were performed at external magnetic fields of ...
