One titrimetric and two indirect spectrophotometric methods are described for the determination of doxycycline hyclate (DCH) in bulk drug and in its formulations. The methods use bromate-bromide, methyl orange and indigo carmine as reagents. In titrimetry (method A), DCH is treated with a known excess of bromate-bromide mixture in acid medium and the residual bromine is back titrated iodometric...
A comparative study was made between the acaricidal activities of some essential oils: rosemary (Rosmarinus officinalis L.), lavandula (Lavandula angustifolia Mill.), thyme (Thymus vulgaris L.) and ziziphora (Ziziphora clinopodioides Lam.) on the important mite pest, Tetranychus cinnabarinus Boisduval, the carmine spider mite, oncut roses during 2010-2012. The sublethal concentrations of ziziph...
In the chironomid Acricotopus lucidus, two cells with quite different chromosome complements arise from the last unequal spermatogonial mitosis, as a consequence of monopolar migration of the so-called germ line limited chromosomes (Ks). The cell receiving all the Ks, in addition to two sets of the regularly segregating somatic chromosomes (Ss), develops into the primary spermatocyte, while the...
We show that the neurological condition of synaesthesia--which causes fundamental differences in perception and cognition throughout a lifetime--is significantly represented within the childhood population, and that it manifests behavioural markers as young as age 6 years. Synaesthesia gives rise to a merging of cognitive and/or sensory functions (e.g. in grapheme-colour synaesthesia, reading l...
