Research ArticleOpen accessEvery word in the titleAnalysis of the 16-20 February 2025 Damaging Heavy Rainfall in BotswanaOliver MosesHeavy rainfall that occurred from 16-20 February 2025 over most of Botswana caused, for example, flash flooding, fatalities, and widespread displacement, with the most severe impacts in the Gaborone-Mochudi region in the southeastern parts of the country. The drivers of this event are poorly understood; hence, this study analyses the rainfall characteristics using CHIRPS and station data. It also analyses … …American Journal of Applied Sciences, Vol. 23, Issue 1 · 24 Aug 2026 · 1,117 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAdding Duckweed (Lemna minor) to Local Duck Diet: Determined Based on the Performance and Heavy MetalConcentration in their MeatSyamsuhaidi, Dwi Kusuma Purnamasari, Ryan Aryadin Putra, Uhud AbdullahAn experiment was conducted to determine whether addingduckweed fertilized with bioslurry to the diet corresponds to duckperformance and heavy metal concentration in their meat. The study wasdesigned using a completely randomized design. The treatments weredifferent levels of adding duckweed as a diet component, as follows: Basalfeed (control, no duckweed, TC), basal feed +2.5% duckweed (TL1), basalfeed +5% duckweed (TL2), basal … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 1 · 13 May 2025 · 5,847 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvaluation of Heavy Metals in Gadus morhua and the Associated Cancer RisksKayode Idowu Ogungbemi, Margaret Bose Adedokun, Josephine Nneamaka Onyeka-UbakaGadus morhua is a good protein source but some methods of its preservation can be a source of heavy metals contamination.
