Thermo-gravimetric analyses of three cellulosic substances, namely, microcrystalline and amorphous cellulose, and treated Japanese cypress (JC) sawdust were carried out in this study. The thermal degradation temperature of crystalline cellulose decreased with increasing ball-milling time, while that of amorphous cellulose barely changed. However, small differences in the derivative thermo-gravi...

This paper presents an integrated assessment model aimed at evaluating land degradation by water erosion in dehesa rangelands in the Iberian Peninsula. The model is built following the system dynamics approach. The degradation risk is likened to the probability of losing a certain amount of soil within a number of years, as estimated over a great number of stochastic simulations. Complementary ...

Ultimate and proximate analyses and thermal degradation of bio-oils from pinewood and palm empty fruit bunches (PEFB) were carried out to evaluate the oils' potential for production of fuels for transport, heat and power generation, and of hydrogen via the calculation of performance indicators. The pinewood and PEFB oils indicated good theoretical hydrogen yields of 13.7 and 15.9 wt.% via steam...

Biodiversity hotspots of the world are increasingly exposed to anthropogenic pressures and resulting ecosystem breakdowns. However, biotic surveys for ecological status assessment rarely conducted in poorly characterised, yet highly diverse ecosystems tropics subtropics. Here, we addressed challenge developing a monitoring system highland streams Indo-Burmese biodiversity hotspot Bangladesh, us...

Land degradation poses a critical threat to the stability and security of ecosystems, especially in salinized areas. Monitoring land areas facilitates management ecological restoration. In this research, we integrated salinization index (SI), albedo, normalized difference vegetation (NDVI) surface soil moisture (LSM) through principal component analysis (PCA) method establish (SDI). Based on SD...
