Natural products present in preferred and non-preferred animal hosts of biting insects can exhibit interesting semiochemical properties. Recently, a novel fatty acid compound that acts as a feeding deterrent for blood sucking insects was identified from the gaur (Bos frontalis). In our laboratory we have prepared analogues of this novel fatty acid and explored their structure activity relations...

No detailed information regarding pestilences in Bengal is available before the Mohammedan period. Farishta, a contemporary of Akbar, mentions the occurrence of bubonic plague in Bihar in 1548. A very devastating pestilence ravaged Gaur*, the medieval capital of Bengal, in 1573. During this epidemic ' Thousands died daily; living were wearied with burying the dead. Corpses of Hindus and Mohamme...

Polarographic technique has been used to evaluate the kinetic parameters and formation constants of Co (П) complexes with benzyl penicillin sodium salt at pH 6.0±0.10 and constant ionic strength (μ = 0.1), HCl in aqueous, aqueous-methanol and aqueous-ethanol mixtures at d.m.e. The effect of concentration and temperature on the half wave potential of the complexes has also been investigated. The...

Searches for $CP$ violation in the two-body decays $D_{(s)}^{+}\rightarrow h^{+}\pi^{0}$ and $D_{(s)}^{+} \rightarrow h^{+}\eta$ (where $h^{+}$ denotes a $\pi^{+}$ or $K^{+}$ meson) are performed using $pp$ collision data collected by LHCb experiment corresponding to either 9 fb$^{-1}$ 6 of integrated luminosity. The $\pi^{0}$ $\eta$ mesons reconstructed $e^{+}e^{-}\gamma$ final state, which ca...
