Aerobic granular sludge is attractive for high-rate biological wastewater treatment. Biomass wash-out conditions stimulate the formation of aerobic granules. Deteriorated performances in biomass settling and nutrient removal during start-up have however often been reported. The effect of wash-out dynamics was investigated on bacterial selection, biomass settling behavior, and metabolic activiti...

Equation of motion for real dust particle under the action of electromagnetic radiation is more general than equation of motion corresponding to standardly used Poynting-Robertson effect (P-R effect). As a consequence, orbital evolution of particles may significantly differ from that corresponding to the P-R effect. The paper discusses recently published (Icarus, June 2002) derivation of equati...

Recent work has shown that perceptual and conceptual processing share a common, modality-specific neural substrate and appear to share the same attentional mechanisms. However, this work has been largely limited to the conceptual processing of unimodal properties (i.e., that involve information from only one sensory modality) even though most perceptual properties are actually multimodal (i.e.,...
