N-H?N and C-H?? interactions in 4-amino-3-methyl-5-(p- tolyl)-4H-1,2,4-triazole and 4-amino-3-methyl-5-phenyl-4H-1,2,4-triazole
(2006)
The title compounds, C10H12N4, (I), and C9H10N4, (II), have been synthesized and characterized both spectroscopically and structurally. The dihedral angles between the triazole and benzene ring planes are 26.59 (9) and ...
A research on the sensitivity of European chub to some pesticides
(2006)
The aim of this study was to investigate the sensitivity of European chub (Leuciscus cephalus, Linnaeus, 1758), a natural freshwater fish species, to a synthetic pyrethroid (deltamethrin), a carbamate insecticide (carbaryl), ...
Molecular epidemiology of clinical Pseudomonas aeruginosa isolates carrying IMP-1 metallo-β-lactamase gene in a university hospital in Turkey
(2007)
Pseudomonas aeruginosa isolates carrying IMP- or VIM-type metallo-?-lactamase (MBL) have been increasingly reported in hospitals worldwide. One hundred P. aeruginosa clinical isolates from unrelated inpatients hospitalized ...
Macroelement (N, P, K) contents of Romulea columnae Seb. and Mauri Subsp. columnae during vegetative and generative growth phases
(Academic Journals Inc., 2007)
Romulea columnae Seb. and Mauri subsp. columnae is a geophytic plant belonging to Iridaceae. In this study nitrogen (N), phosphorus (P) and potassium (K) analysis were carried out during vegetative and generative growth ...
Seasonal variation in plant biomass in a salt marsh community in northern Turkey
(2007)
Seasonal pattern in above- and belowground live and dead biomass in a salt marsh community was investigated. Multiple peaks were observed in terms of all biomass types. Maximum aboveground live and dead biomass was observed ...
Chemical composition and antimicrobial activities of the essential oil from the flowers of Delphinium formosum
(2007)
The essential oil from the flowers of Delphinium formosum Boiss. et Huet. (Ranunculaceae) was obtained by hydrodistillation in a Clevenger-type apparatus and analyzed by GC-MS. 68 Components were identified in the oil. The ...
Analysis of regional wild-type cereals in Trabzon-Turkey by EDXRF spectrometry
(2007)
The energy dispersive X-ray fluorescence (EDXRF) spectroscopy was used to determine essential and trace element contents of some naturally grown wild-type cereals collected in different regions of Trabzon, Turkey. The ...
