Reaction of thionyl chloride with 2-acetyl-1- benzenesulfonylpyrrole semicarbazone (6 c) gave 4 - (1- benzenesulfonyl-2 - pyrrolyl) - 1, 2, 3 -thiadiazole (lc). Selenium dioxide oxidation of 2-acetylpyrazine semicarbazone (10) in acetic acid afforded 4- (2-pyrazinyl) - 1, 2, 3- selenadiazole (4). Reaction of thionyl chloride with compound 10 gave 4- (2-pyrazinyl) - 1, 2, 3- thiadiazole (3)....

Bushfire management which incorporates fire potential indices is still in its infancy Jamaica and the Caribbean. In this study three bushfire indices—Keetch–Byram Drought Index (KBDI), Vapour Pressure Deficit (VPD) Water Potential (Ψw)—are calculated for south-central where frequencies are highest. The skills of evaluated using their representation normalised climatology, monthly seasonal (Dece...
