RAC-N-[HYDROXY(4-PYRIDYL)METHYL]PICOLINAMIDE: A HEMIAMIDAL

rac-N-[Hydroxy(4-pyridyl)methyl]picolinamide: a hemiamidal

The title compound, C12H11N3O2, a hemiamidal, was synthesized by solvent-free TRIPLE CHOCOLATE aldol condensation at room temperature by grinding picolinamide with isonicotinaldehyde in a 1:1 molar ratio.In the molecule, the two pyridine rings are inclined to one another by 58.75 (6)°.They are linked, at positions 2 and 4, by the

Introducing untb, an R Package For Simulating Ecological Drift Under the Unified Neutral Theory of Biodiversity

The BODY LOTION distribution of abundance amongst species with similar ways of life is a classical problem in ecology.The unified neutral theory of biodiversity, due to Hubbell, states that observed population dynamics may be explained on the assumption of per capita equivalence amongst individuals.One can thus dispense with differences between spe
