Helical supramolecular assembly of N2,N2')bis[3-(morpholin-4-yl)propyl]-N1,N1'-(1,2-phenylene)dioxalamide dimethyl sulfoxide monosolvate.

In the title compound, C(24)H(36)N(6)O(6)·C(2)H(6)OS, the carbonyl groups are in an antiperiplanar conformation, with O=C-C=O torsion angles of 178.59 (15) and -172.08 (16)°.

N,N'-Bis(4-amino-benz-yl)oxalamide.

In the title compound, C(16)H(18)N(4)O(2), the two carbonyl groups are in an anti-periplanar conformation with an O=C-C=O torsion angle of 173.86 (17)°. In the crystal, a pair of inter-molecular N-H⋯O hydrogen bonds, forming an R(2) (2)(10) ring motif, connect the mol-ecules into an inversion dimer.

Dynamics of carbon, nitrogen and phosphorus in soil amended with irradiated, pasteurized and limed biosolids.

Sewage biosolids contain high concentrations of pathogens, which limits their use as soil amendment. This study investigated how application of lime (Ca(OH)2), irradiation, or pasteurization reduced pathogens in biosolids and how its application affected soil characteristics. A soil sampled outside the canopy of Mesquite trees (Prosopis laevigata) and from a pasture at Lerma (Mexico) was amended with treated or untreated biosolids, characterized and incubated aerobically while dynamics of carbon (C), nitrogen (N) and phosphorus (P) were monitored.
