5-HYDROXY-7-METHOXY-2-METHYL-4H-CHROMEN-4-ONE FROM DYSOXYLUM MACROCARPUM (MELIACEAE)

Both independent molecules in Brush Bar the asymmetric unit of the title compound, C11H10O4, are almost planar (r.m.s.deviations = 0.011 and 0.033 Å).In both molecules, the hydroxy group is intramolecularly hydrogen bonded to the ketonic O atom.The independent molecules are Wrist Support stacked alternately along the a axis, with

The trajectory tracking task of a magnetic levitation system connected to a beam mechanism is solved by means of a nested saturation control with a feedforward term.The flatness Credenza property of the system allows to use the nested saturation control technique and the feedforward control to HAIR LOSS stabilize the output tracking error around th
