We study the nonlinearity (NL) in the conversion from charge to voltage in infrared detectors (HXRG) for use in precision astronomy. We present laboratory measurements of the NL function of a H2RG detector and discuss the accuracy to which it would need to be calibrated in future spacemissions to perform cosmologicalmeasurements through theweak gravitational lensing technique. In addition, we p...

The impact of water use in areas with abundant freshwater resources should not be the same as areas with limited resources. This impact is quantified as water scarcity footprint. The monthly water stress index with reference to environmental water requirement is proposed as a characterization factor. The biofuel policies of Thailand—cassava and sugarcane for bioethanol, and oil palm for biodies...

Lao People’s Democratic Republic (PDR) has been experiencing significant forest depletion since the 1980s, but there is little evidence to demonstrate the major causes and underlying drivers for the forest cover changes. In this study, we investigated the relationship between forest cover decrease and increase in the south of Lao PDR between 2006 and 2012 and selected physical and socio-economi...

The participation of women in agriculture and the role of women in society in the preindustrial period were remarkably different across ethnicities and strongly related to the type of agricultural technology adopted historically. The sexual division of labor was broadly associated to two technological regimes: shifting cultivation, where the majority of agricultural work was done by women, and ...

Fallow forests, which have been generated by shifting cultivation, cover large parts of the highlands of Northern Thailand. This paper presents the case study of a village, in which a particularly sustainable form of shifting cultivation was practiced until the early 1990s. Secondary forests, which regenerate on the fallow swiddens of this village were found to be surprisingly rich in tree spec...
