Human Immunodeficiency Virus-1/AIDS and Schistosoma mansoni are widespread in sub-Saharan Africa and co-infection occurs commonly. Since the early 1990s, it has been suggested that the two infections may interact and potentiate the effects of each other within co-infected human hosts. Indeed, S. mansoni infection has been suggested to be a risk factor for HIV transmission and progression in Afr...

The simplest scenario for the three known light neutrinos that fits the solar and atmospheric neutrino deficit and a mixed dark matter (MDM) picture of the universe requires them to be highly degenerate with mν ∼ 1 2 eV. We propose an SO(10) grand unified model with an S4-horizontal symmetry that leads naturally to such a scenario. An explicit numerical analysis of the quark and lepton sector o...

In the crystal structure of the title compound, C(10)H(12)ClNO(3)S, the N-C bond in the C-SO(2)-NH-C segment has a gauche torsion with respect to the S=O bonds. The mol-ecule is twisted at the S atom with a C-S-N-C torsion angle of -62.3 (3)°. The benzene ring and the SO(2)-NH-CO-C segment form a dihedral angle of 89.3 (1)°. In the crystal, mol-ecules are linked by pairs of N-H⋯O hydrogen bonds...
