Effect of partial mutton meat substitution with Bambara groundnut (Vigna subterranea (L.) Verdc.) flour on physicochemical properties, lipid oxidation, and sensory acceptability of low-fat patties. [PDF]

open access: yesFood Sci Nutr
Physicochemical properties, lipid oxidation, and sensory acceptability of low‐fat mutton patties substituted with Bambara groundnut flour were determined. The increase in the percentage substitution of BGN flours significantly increased the fiber, ash, and carbohydrate contents of the formulated mutton patties.

Response and resilience of karst subterranean estuary communities to precipitation impacts

open access: yesEcology and Evolution, Volume 13, Issue 8, August 2023., 2023
Heavy precipitation events caused a halocline shift resulting in a mortality event at a karst subterranean estuary, affecting the fauna inhabiting under the halocline (dotted white line) at the marine groundwater layer (a‐b). Overall, marine species (c‐e) inhabiting the caves were impacted, and cave‐adapted fauna (f‐i) remain resilient to short‐term ...

Groundwater mapping and locally engaged water governance in a small island terrain: Case study of Karainagar island, Northern Sri Lanka

open access: yesWorld Water Policy, Volume 9, Issue 3, Page 456-480, August 2023., 2023
Abstract Groundwater is a vital resource under threat in island communities. Karainagar, a 22 km2 island, is one of seven islands off the coast of Jaffna in Northern Sri Lanka, with its population of just about 11,000 persons, experiences seasonal water shortage, and salinity in groundwater as twin threats impacting on their lives.
