The present work reviews the role of biogas as advanced biofuel in the renewable energy system, summarizing the main raw materials used for biogas production and the most common technologies for biogas upgrading and delving into emerging biological methanation processes.In addition, it provides a description of current European Bike Parts - Brakes
The continuum from Earth and Sky reminds humanity of his fortuitous origin; this means, everything remains in suspense.Against this telluric horror, mankind opposes a static world: beset by security MACA POWDER and welfare, stranded in the mechanical order (labour servility), ignores the movement of the universe.This is a world conceived by and for
Abstract A highway embankment founded on a sloping REISHI tectonised marly-sandstone flysch formation located in the Apennines chain (Italy) has been affected for about 30 years by continuous slow movements.Given the strategic importance of the involved infrastructure, different investigation and monitoring campaigns have been carried out to get in
The key to the realization of air-water trans-medium flight lies in the profile design of trans-medium flight and the satisfaction of different requirements of aerodynamic efficiency for air cruise and airfoil for underwater glide.In this paper, a trans-medium flight profile scheme based on the fusion design of traditional fixed-wing vehicles and u
Background: The efficiency of immune checkpoint inhibitors (ICIs) in bladder cancer (BLCA) treatment has been widely validated; however, the tumor response to ICIs was generally low.It is critical and urgent to find biomarkers that can predict tumor response to ICIs.The tumor microenvironment (TME), which may play important roles to either dampen o
