Abstract:
... Black carbon (BC) has importance regarding aerosol composition, radiative balance, and human exposure. This study adopted a backward-trajectory approach to quantify the origins of BC from anthropogenic emissions (BCAn) and open biomass burning (BCBB) transported to Xishuangbanna in 2017. Haze months, between haze and clean months, and clean months in Xishuangbanna were defined according to daily P ...

Subject:
highlands; land tenure; peasantry; rice; rubber; villages; Laos
Abstract:
... This paper highlights how farmers in a northern Lao village transformed their customary land rights – in the face of incoherent overlapping state territorialization attempts – into a territorial strategy to secure their land tenure. By planting rubber, some villagers have engaged in a crop boom to lay claim to land which has recently been zoned for upland rice cultivation (and conservation) as par ...

Abstract:
... Bloodstream infections (BSIs) are a leading cause of sepsis, which is a life-threatening condition that significantly contributes to the mortality of bacterial infections. Aminoglycoside antibiotics such as gentamicin or amikacin are essential medicines in the treatment of BSIs, but their clinical efficacy is increasingly being compromised by antimicrobial resistance. The aminoglycoside apramycin ...
