Visceral leishmaniasis in non-endemic rural hilly region of Nepal: A case report.

Visceral leishmaniasis is the most severe form of leishmaniasis, caused by the obligate intracellular protozoan parasites or , transmitted by the bite of phlebotomine sand fly. Visceral leishmaniasis is a disease of lowlands and uncommon in highlands. We report a case of visceral leishmaniasis in 13-year-old female patient from a village of Arghakhanchi situated at an altitude of 1200 m.

Tunable band gaps and optical absorption properties of bent MoS nanoribbons.

The large tunability of band gaps and optical absorptions of armchair MoS nanoribbons of different widths under bending is studied using density functional theory and many-body perturbation GW and Bethe-Salpeter equation approaches. We find that there are three critical bending curvatures, and the non-edge and edge band gaps generally show a non-monotonic trend with bending. The non-degenerate edge gap splits show an oscillating feature with ribbon width n, with a period [Formula: see text], due to quantum confinement effects.
