We investigate the flow of liquids around solid surfaces in the inertial regime, a situation commonly encountered with the so-called "teapot effect", the annoying tendency for a liquid to trickle down the outside of a receptacle after pouring. We demonstrate that surface wettability is an unexpected key factor in controlling flow separation and trickling, the latter being completely suppressed ...

14 This study investigates the mesophilic biohydrogen production from glucose using a strictly 15 anaerobic strain, Clostridium butyricum CWBI1009, immobilized in a trickling bed sequenced 16 batch reactor (TBSBR) packed with a Lantec HD Q-PAC ® packing material (132 ft2/ft3 specific 17 surface). The reactor was operated for 62 days. The main parameters measured here were 18 hydrogen compositio...

Sewage treatment plant effluents were surveyed for viral contributions to gastroenteritis outbreaks in Puerto Rico. Of the 15 sewage treatment plants studied, all discharged their effluents upstream from water treatment plant intakes. No base-line data on the degree of viral challenge to these sewage treatment plants or the subsequent reduction of viruses before discharge existed. Enterovirus c...

To find a simple and economical way for treating the domestic wastewater in small counties and towns, a process combining chemically enhanced primary treatment and a trickling filter (CEPT-TF, representing the physical and biological effects) was constructed and operated in laboratory conditions. The characteristic behaviors of dissolved organic matter in raw wastewater and effluents were exami...

By maintaining a focus on managers in driving the implementation of management concepts, with meaning-making ‘trickling down’ the organization, translation perspectives have provided little detail about translation across intra-organizational boundaries. This study focuses on the boundary-spanning practices of intermediate agents championing the implementation of Lean in a hospital setting. Bas...
