The title compound, C11H14N2O2, contains two independent mol-ecules in the asymmetric unit. Each independent mol-ecule exists as part of an N - H?O hydrogen-bonded centrosymmetric dimer. © International Union of Crystallography ...
Biotypes and antibiotic resistance patterns of Gardnerella vaginalis strains isolated from healthy women and women with bacterial vaginosis
(2007)
As Gardnerella vaginalis is accepted as a member of normal vaginal flora, it is one of the dominant species which has been related to bacterial vaginosis (BV). The aim of this study was to determine the isolation rate, ...
Assessment of mercuric chloride toxicity on rainbow trouts (Oncorhynchus mykiss) and chubs (Alburnoides bipunctatus)
(Asian Network for Scientific Information, 2007)
Acute toxicity of mercury-II chloride (HgCl2), one of most toxic pollutants for aquatic ecosystems, in chub (Alburnoides bipunctatus) and rainbow trout (Oncorhynchus mykiss) was investigated in the present study. Actual ...
4-(4-Allyl-2-meth-oxyphen-oxy)benzene-1,2-dicarbonitrile

(Magnolia Press, 2008)
Luciobarbus kottelati, new species, is described from the River Büyük Menderes, Aegean Sea drainage, Turkey. It is distinguished from all other species of Luciobarbus in Europe and western Anatolia by the pelvic-fin origin ...
Gadolinium diffusion-doping for enhancing activation energy in superconducting YBa2Cu3O7-x
(Elsevier, 2008)
The resistance transitions of Gd-diffused polycrystalline Y123 samples have been measured as a function of temperature and magnetic field. It is deduced from experimental results that the activation energy increases when ...
