Two upflow sludge bed reactors (UASB) were operated for 80 days at 55 degrees C with methanol as the substrate with an organic loading rate (OLR) of about 20 g CODl(-1) per day and a hydraulic retention time (HRT) of 10 h. One UASB was operated without sulphate addition (control reactor-R1) whereas the second was fed with sulphate at a COD:SO4(2-) ratio of(More)
For many years robotics has been benefited from the open source community. Software community projects like Player, Stage, Gazebo, ROS, or OpenCV are present in most robotic applications. In recent years this trend has also been initiated among electronic and mechanical developments (open hardware). The Arduino development platform is a good example of a(More)
