-almost periodic and almost periodic solutions for some nonlinear integral equations
In this paper, we investigate the existence of -almost periodic solution for a class of nonlinear Fredholm integral equations, and the existence of almost periodic solution for a class of nonlinear functional integral equations. Our existence theorems extend some earlier results. Two examples are given to illustrate our results
Tizoxanide pyridine monosolvate
In the title compound [systematic name: 2-hyÂdroxy-N-(5-nitro-1,3-thiaÂzol-2-yl)benzamide pyridine monosolvate], C10H7N3O4S·C5H5N, the dihedral angle between the pyridine and benzamide rings is 80.55 (7)°. An intamolecular O—H⋯N hydrogen bond occurs in the tizoxanide. In the crystal, the components are linked by an O–H⋯N hydrogen bond, forming a zigzag chain along the c axis. Aromatic π–π interÂactions between inversion-related pyridine rings [centroid–centroid distance = 3.803 (6) Å] are also observed
