Embryogenic cultures were initiated from immature Melia azedarach (Meliaceae) zigotic embryos. Explants were induced on Murashige and Skoog (1962) medium with 4.54 microM thidiazuron or 0.45 microM dichlorophenoxyacetic acid. After 6 weeks of culture on induction medium, somatic embryos were categorized in four morphological classes based on the presence of single or fused embryos and if they r...

Many explanations in science make use of mathematics. But are there cases where the mathematical component of a scientific explanation is explanatory in its own right? This issue of mathematical explanations in science has been for the most part neglected. I argue that there are genuine mathematical explanations in science, and present in some detail an example of such an explanation, taken fro...

Screening of phenolic constituents in leaves of Cedrela serrata, Toona ciliata, Azadirachta indica and Melia azedarach was done by reversed phase high performance liquid chromatography (RP-HPLC). The phenolic compounds were identified by comparison with authentic standards. The phenolic acids identified in all plants leaves extract were gallic acid, protocatechuic acid, p-hydroxy benzoic acid, ...
