In the title compound, C(10)H(13)NO(3)S, the conformations of the N-H and C=O bonds of the SO(2)-NH-CO-C segment are anti to each other, while the amide H atom is syn with respect to the ortho-methyl group in the benzene ring. The C-S-N-C torsion angle is -66.7 (2)°. The crystal structure features inversion-related dimers linked by pairs of N-H⋯O(S) hydrogen bonds.

For 3 ≤ k ≤ 20 with k 6= 4, 8, 12, all the smallest currently known k–regular graphs of girth 5 have the same orders as the girth 5 graphs obtained by the following construction: take a (not necessarily Desarguesian) elliptic semiplane S of order n− 1 where n = k − r for some r ≥ 1; the Levi graph Γ (S) of S is an n–regular graph of girth 6; parallel classes of S induce co–cliques in Γ (S), som...

gallium extraction from jajarm bayer process liquor (jajarm, iran) was investigated using microemulsions. also the behavior of aluminum was studied as an impurity. kelex100 (4-ethyl, 1-methyl, 7-octyl, 8-hydroxyquinoleine), iso-decanol and n-butanol, and kerosene were used as the surfactant, co-surfactant, and oil phase, respectively. ternary phase diagrams were produced using various co-surfac...

manfaluti is one of egyptian authors in 20th century who paid most attention to social and mental issues of egypt nation. thus perhaps it is better to introduce manfauti as a scholar rather than literary man so that his readers have been interested in his works because of their social subjects since long time ago. some believe that manfaluti's works contain no technical elements. hence, th...
