(Int Union Crystallography, 2007)A complex of Ni (II) with 2,6- diacetylpyridinedihydrazone (L) towards nickel(II) has been prepared and characterized by means of elemental analyses, IR, electronic spectra and single crystal X-ray analyses. [NiL2](NO3), ... -
Effect of cypermethrin exposed hosts on egg-adult development time, number of offspring, sex ratio, longevity, and size of Apanteles galleriae Wilkinson (Hymenoptera : Braconidae)
(Soc Royale Zoologique Belgique, 2007)The effects of sub-lethal doses of cypermethrin onto the larval host Achoria grisella Fabr. (Lepidoptera : Pyralidae) were evaluated on egg-adult development time, number of offspring produced, sex ratio, longevity, and ... -
Sulfonamide inhibition study of the beta-class carbonic anhydrase from the caries producing pathogen streptococcus mutans
(Pergamon-Elsevier Science Ltd, 2015)Streptococcus mutans, the oral pathogenic bacterium provoking dental caries formation, encodes for a beta-class carbonic anhydrase (CA, EC 4.2.1.1), SmuCA. This enzyme was cloned, characterized and investigated for its ... -

The relationships between certain physical and chemical variables and the seasonal dynamics of phytoplankton assemblages of two inlets of a shallow hypertrophic lake with different nutrient inputs
(Springer, 2007)dThe relationships between water discharge, temperature, total dissolved solids (TDS) conductivity, turbidity, nitrate, ammonium, phosphate and the seasonal dynamics of phytoplankton assemblages of two inlets of a shallow ... -
Identification of cytotoxic sesquiterpenes from Laurus nobilis L.
(Elsevier Sci Ltd, 2007)A new sesquiterpene, lauroxepine and six known sesquiterpene lactones, were obtained through bioactivity-directed isolation from a methanol extract of the fruits of Laurus nobilis. The hexane-soluble part of the methanol ... -
Spatial and seasonal variations in chlorophyll-nutrient relationships in the shallow hypertrophic Lake Manyas, Turkey
(Springer, 2006)Regression and correlation analyses were used to predict responses of phytoplankton biomass (chlorophyll) (mu g L-1) to nitrate (NO3) (mg L-1), phosphate (PO4) (mg L-1) and ammonium (NH4) (mg L-1) dynamics in the shallow ... -
