New Palladium II and Platinum II Complexes Based on Pyrrole Schiff Bases- Synthesis, Characterization, X‑ray Structure, and Anticancer Activity
(University of Nairobi, 2020)New palladium (Pd)II and platinum (Pt)II complexes (C1−C5) from the Schiff base ligands, R-(phenyl)methanamine (L1), R-(pyridin-2-yl)methanamine (L2), and R-(furan- 2-yl)methanamine (L3) (R-(E)-N-((1H-pyrrol-2-yl) ... -
New Perspectives In Vertebrate Paleoecology From A Recent Bone Assemblage
(University of Nairobi, 1979)Abstract.-Interpretations of vertebrate paleoecology depend on knowledge of taphonomical processes which alter the composition of the preserved fossil assemblage from that of the original community. Study of the potential ... -
