Biomass gasification is a technology that has attracted great interest in synthesis of biofuels and oxo alcohols. However, this gas contains several contaminants, including tar, which need to be removed. Removal of tar is particularly critical because it can lead to ope...

The spatial distribution of secondary electrons produced in the γ-radiolysis of water in the liquid phase has been theoretically calculated. The method consists of the combination of the procedure previously developed for the calculation of the G-value of electrons with...

To demonstrate the robustness of extraction systems against radiolytic degradation is nowadays one of the limiting points to ensure a safe and stable operation for advanced nuclear fuel strategies. In this paper, is addressed the stability of one of most promising extra...

Attempts to influence the development of land systems are often based on detailed scenarios that constrain relevant factors, describe a range of divergent but plausible futures and identify potential pathways to visions of desirable conditions. However, a number of assu...

Treat), or a combination of both types. The choice of the most suitable technique is a difficult task, since various aspects must be taken into consideration. In this paper, we present a framework for evaluating barriers in terms of effectiveness and efficiency, along w...

Investigation of temperature effect on mechanical parameters of coal is very important for understanding the mechanical response of coal bed at high temperature. It is especially beneficial for mitigating the thermal-induced disasters occurred in those coal mines suffer...

Abstract Membrane vesicles prepared from Escherichia coli B/r grown on glutamate as a sole source of carbon and energy require sodium for glutamate accumulation when energized by D-lactate oxidation. Glutamate uptake can also be driven by a prearranged sodium gradient (...

This paper uses Data Envelopment Analysis to examine the relative productive efficiency of a sample of 78 publicly- and privately-owned nuclear power plants operating the year 1989. The sample includes 13 UK nuclear power plants. Linear programs are used to calculate a ...

Abstract Although short-rotation coppice (SRC) is a sustainable cultivation technique, biodiversity issues keep policy makers from encouraging farmers to establish SRC. From the 47 reviewed publications of this review 91% reported on poplar or willow SRC, and 63% focuse...

[EN] Off grid electrification is key to achieving universal electricity access. Despite the potential of biomass gasifiers as a clean technology to ensure reliable systems, they are not as well looked upon as their advantages suggest. In particular, the software HOMER, ...
