Fate of PCBs, PAHs and their source characteristic ratios during composting and digestion of source-separated organic waste in full-scale plants

Joseph Tarradellas

Composting and digestion are important waste management strategies. However, the resulting products can contain significant amounts of organic pollutants such as polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs). In this study we ...

Is phosphorus retention in autochthonous lake sediments controlled by oxygen or phosphorus?

Alfred Johny Wüest, Beat Mueller

Eutrophication of various lakes on the Swiss Plateau was targeted in the 1980s by reducing external nutrient loading and installing aeration/oxygenation systems. For five eutrophic lakes, three of which have been artificially oxygenated and aerated for alm ...

Model checking for Synchronous Java

Claude Petitpierre, Duy Vo Duc

In this paper, we present a model-checking toolset for a synchronous version of the Java language (Synchronous Java or in short sJava). The toolset includes a set of extensions to the Bandera and Bogor model-checking frameworks. It inherits thus a large nu ...
