“…This research focuses on fabricating novel bricks reinforced with different percentages of coconut waste fibre, wheat straw fibre, waste wood animal dung ash, gypsum, sand, and cement. The fabricated novel brick's physical, mechanical, chemical, acoustic, and heat-absorbing properties were evaluated.…”

“…BACKGROUND: Leishmania parasites are transmitted to their vertebrate hosts by infected Phlebotomine sand flies during the blood meal of the flies. Sand fly saliva is known to enhance Leishmania spp. infection, while pre-exposure to saliva protects mice against parasitic infections. …”
