The aim of this study was to investigate the use of biogas production rate kinetics for the monitoring of anaerobic co-digestion. Recent extensive studies of degradation pathways showed that acetoclastic methanogenesis is not always the main pathway. Hydrogenotrophic methanogenesis and syntrophic acetate oxidation can also dominate, mostly for oper...

Nitrification plays an important role in nitrogen turnover in composting process. It has been believed that nitrification occurs mainly during the maturation phase due to the elevated temperature during the active phase of composting. In this work, the intense biodegradation of organic matters is demonstrated to be another negative impact on the am...
The worldwide production of bamboo generates large volumes of leaf wastes, which are deposited in landfills or burned in an uncontrolled manner, with negative effects in the environment. The ash obtained by calcining of the bamboo leaf waste, shows good qualities as supplementary cementing material for the production of blended cements. The current...

The influence of the temperature, the pressure, the Al/Ni molar ratio, and the position of chlorine-containing substituents in formazan ligands on the reaction kinetics and the product composition in the ethylene oligomerization catalyzed by thea system based on nickel(II) formazanates and ethylaluminium dichloride has been studied. It has been sho...
The new technology of process intensification by multiscale equipment can significantly contribute to the achievement of a safer design by switching from batch/semi-batch to continuous operation combined with a reduction of the inventory of hazardous substances in critical stages. On the other hand, the shift to higher space-time-yields and tempera...
Colorimetric and spectral characteristics of pyrimidinylformazanes and their complexes with transition-metal ions are studied in solution and on solids. Reagents suitable for the visual determination of copper(II) and silver(I) ions and for the sorption spectroscopic determination of copper(II) ions are recognized. © Pleiades Publishing, Inc., 2006...

The large-scale experiments CometPC-H4 and -H5 investigate cooling of simulated corium melts by flooding the melt from the bottom through layers of porous, water filled concrete. Both experiments use 800 kg of oxidic and metallic melts, initial temperature from 1800 to 1900 C, with simulation of nuclear decay heat by inductive heating with 300 KW t...
