Uncontrolled growth of the urban population in developing countries in recent years has made solid waste management an important issue. Today municipal solid waste management (MSWM) is one of the most challenging issues in urban cities, which are facing a serious pollution problem due to the generation of huge quantities of solid waste. This results in development of environmentally sustainable...

In the title compound, C(24)H(25)N(3)S(2), the S-bound benzene rings have orthogonal [dihedral angle = 85.31 (9)°] and splayed [67.92 (11)°] orientations with respect to the pyrimidine ring; the dihedral angle between the benzene rings is 48.18 (12)°. The pentyl group has an extended all-trans conformation and lies to one side of the pyrimidine ring [the N(py)-C(py)-C(p)-C(p) torsion angle = -8...

In the title compound, C(11)H(11)ClN(4)O(3)S, the S atom is bonded in a distorted tetra-hedral geometry, by two O atoms, a C atom of the benzene ring and an amino N atom. The essentially planar pyrimidine ring [maximum deviation = 0.020 (1) Å] forms a dihedral angle of 87.57 (5)° with the benzene ring. In the crystal structure, pairs of mol-ecules are linked by inter-molecular N-H⋯O hydrogen bo...

Multiple argument dispatching is a natural extension of single-argument, or receiver-based, dispatch. Recently several techniques were proposed that aim to make multiple dispatch an efficient operation. However, none of the studies has actually analyzed run-time behavior. In this study we compare several techniques, two of which are presented for the first time, by writing down abstract assembl...
