Evaluation of Air Inlet Configuration's Effect on Biochar Properties From African Mesquite Pod Carbonization

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 1, January/February 2026.
ABSTRACT The suboptimal efficiency of current biomass conversion processes necessitates the optimization of biochar production methodologies to enhance desired biochar characteristics. In this study, an investigation was conducted to determine the optimal air inlet configuration within a top‐lit updraft gasifier system for enhancing biochar properties ...

Understorey bird responses to the abandonment of artisanal gold mining in Guyana

Journal of Applied Ecology, Volume 62, Issue 10, Page 2774-2786, October 2025.
Whilst many forest‐dependent birds will avoid the exposed mine centre, diversity at the immediate edge has the potential to recover, particularly in smaller and older mines. As we have found that natural vegetation recovery occurs at the mine edges and not within the centre, targeted restoration efforts might focus on mine edges to enhance recovery ...

Repeated mining accounts for the majority of artisanal and small-scale gold mining activity in Southeastern Peru

Environmental Research Letters
Artisanal and small-scale gold mining (ASGM) is considered a leading cause of environmental degradation in the Amazon. Previous studies have only used deforestation to quantify total ASGM activity and have not considered that mining may occur multiple ...

HPDL Variant Type Correlates With Clinical Disease Onset and Severity

Annals of Clinical and Translational Neurology, Volume 12, Issue 7, Page 1360-1367, July 2025.
ABSTRACT Objective Recently, a mitochondrial encephalopathy due to biallelic HPDL variants was described, associated with a broad range of clinical manifestations ranging from severe, infantile‐onset neurodegeneration to adolescence‐onset hereditary spastic paraplegia. HPDL converts 4‐hydroxyphenylpyruvate acid (4‐HPPA) into 4‐hydroxymandelate (4‐HMA),
