A mineral salts medium containing 1% (w/v) glucose was subjected to anaerobic digestion in an upflow reactor. Performance with respect to utilization of glucose was monitored by collection of fermentation gases and calculation of carbon mass balances. Sub-samples of bacterial supennsions from the upflow reactor were incubated with (U-14C)-glucose,(More)
A mineral salts medium containing 1% (w/v) glucose providing carbon-limited growth conditions was subjected to anaerobic acidogenesis by mixed populations of bacteria in chemostat cultures. The formation of butyrate was shown to be dependent on the presence of saccharolytic anaerobic sporeformers in the acid-forming population. By the use of pasteurized(More)
Tests at the new ‘Havenspoorlijn’ (Harbor Railway Line) in The Netherlands asked for the measurement of all currents at eight positions of the railway. The differentiating/integrating measurement scheme with Rogowski coils and special integrators fulfilled the requirements with respect to accuracy, bandwidth, electromagnetic compatibility, life-time and(More)
At the moment 25 kV traction power supply systems are being introduced in the Netherlands. Currently in the Netherlands a 1500 V DC system is used, however due to increasing energy demands this system is no longer sufficient. For the high-speed lines and heavy freight lines, which are under construction, the 2x25 kV AC system has been chosen. Introduction(More)
