We study the recent upper crustal heat flow variations caused by long-term physical processes such as paleoclimate, erosion, sedimentation and mantle plume upwelling. As specific heat flow is a common lower boundary condition in many models of heat en fluid flow in the Earth’s crust we quantify its long-term transient variation caused by paleoclimate, erosion or sedimentation, mantle plume upwelling and deep groundwater flow. The studied area extends between the Eifel mountains and the Maas river inCentral Europe. The total variation due to these processes in our study area amounts to tectonic events manifested in the studied area 20 mW/m2, about 30% of the present day specific heat flow in the region.

Small-scale biorefinery from sugarcane bagasse offers new possibilities to the sugar and ethanol *** aim of this study was to evaluate the feasibility of a small-scale biorefinery for the production of xylitol from sugarcane *** liquid fraction from the autohydrolysis treatment was selected as the source of sugars for xylitol and two scenarios were analyzed for the residual solid:ethanol or pellet production.A technical-economic analysis of alternatives was *** internal rate of return(IRR)was used to compare the selected *** highest IRR values were obtained when processing 70,000 dry tons per year of *** results showed promising prospects for a small-scale biorefinery with capacities above 20,000 dry tons per year(xylitol and pellets),and above 50,000 dry tons per year(xylitol and ethanol).
