Late Silurian to early Devonian lycophytes had prostrate aerial axes, while subordinate organs or subterranean axes were formed around the dichotomies of axes. The are hypothesized have evolved into root-bearing (rhizophores) and roots in extant Selaginellaceae Lycopodiaceae, respectively. Consistent with this hypothesis, rhizophores on shoots Selaginellaceae. However, it has remained unclear w...

Cholelithiasis is the commonest diseases of Gall bladder which remains asymptomatic and often an incidental finding presents as Right upper Quadrant pain, yellow coloured urine, jaundice or Clay stools. The incidence more among women when compared to men due influence Estrogen Progestrone fluctuations. increase also associated with Polycystic Ovarian disease leading Irregular cycles. Homeopathi...

numerous investigations have been devoted towards understanding the hydrodynamics of gas jets in fluidized beds. however, most of them address the problem from  macroscopic point of view, which does not reveal the true behavior in the jet region at the single particle level. the present work aims to understand the jet behavior from a more fundamental level, i.e. the individual particle level. a...

The collective total synthesis of Lycopodium alkaloids (+)-fawcettimine (1), (+)-fawcettidine (2), (+)-alopecuridine (4), (-)-lycojapodine A (6), and (-)-8-deoxyserratinine (7) has been accomplished from a common precursor (15) based on a highly concise route inspired by the proposed biosynthesis of the fawcettimine- and serratinine-type alkaloids. An intramolecular C-alkylation enabled efficie...
