The aim of this work is to evaluate the influence of cyclophosphamide and its principal metabolites (CPs) on microbial behaviour in a membrane bioreactor system. Two laboratory-scale membrane bioreactors (MBR) were run in parallel with a sludge retention time of 70 days (one with the cytostatic drugs, MBR-CPs, the second without, MBR-control). The microbial activity was measured by respirometri...

This paper uses calibrated versions of a sticky-price currency-substitution model to compare the initial dynamics and welfare costs of three types of stabilization program: Ž . Ž . exchange-rate-based ERB , money-based MB , and money-based with initial reliqueficaŽ . tion MBR . ERB and MBR programs are found to induce an initial expansion in real activity, whereas MB programs are initially cont...

This study investigated the effects of salinity increase on bacterial community structure in a membrane bioreactor (MBR) for wastewater treatment. The influent salt loading was increased gradually to simulate salinity build-up in the bioreactor during the operation of a high retention-membrane bioreactor (HR-MBR). Bacterial community diversity and structure were analyzed using 454 pyrosequencin...

Minimum Bayes Risk (MBR) has been used as a decision rule for both singlesystem decoding and system combination in machine translation. For system combination, we argue that common MBR implementations are actually not correct, since probabilities in the hypothesis space cannot be reliably estimated. These implementations achieve the effect of consensus decoding (which may be beneficial in its o...

Membrane bioreactor technology represents the most rapidly growing membrane technology in the water sector. In recent years, MBR technologies have been playing a very important role in water and wastewater treatment. MBRs are used to treat a wide range of municipal and industrial wastewaters. MBR integrates membrane filtration with biological degradation system of waste products. It is defined ...

Membrane Bioreactor (MBR) process consists of a biological reactor integrated with membranes that combine clarification and filtration of an activated sludge process into a simplified, single step process. The membrane is an absolute barrier to suspended matter and microorganisms and it offers the possibility of operating the system at high mixed liquor suspended solids (MLSS) concentration. Th...

PURPOSE The purpose of this study was to evaluate the correlation between laser speckle flowgraphy measurements of mean blur rate (MBR) and hydrogen gas clearance measurements of capillary blood flow (CBF) in the optic nerve head (ONH) of albino and pigmented rabbits, with or without chronic ischemia-induced ONH atrophy. METHODS The ONH MBR and ONH CBF were measured at baseline, 30 and 60 min...

PURPOSE To describe the utility of school-wide use of mission-based reporting (MBR) for medical school deans and department chairs. METHOD All faculty members in the University of California, Davis, School of Medicine reported their clinical, creative, teaching, and service activities for 2000-2001 to the MBR system. The authors report on school-wide and department MBR profiles, and profiles ...

Human adenoviruses (HAdVs) in wastewater samples taken from four different treatment stages of a full-scale municipal wastewater treatment plant (i.e., incoming raw sewage, primary sedimentation effluent, membrane bioreactor (MBR) influent, and MBR effluent) were quantified by real-time PCR assays to further estimate removal efficiency of the HAdVs. Based on hexon gene sequence comparisons, HAd...

This study demonstrated the importance, process, activation and applications of Membrane in bioreactor to treat the waste water. Membrane Bioreactor (MBR) process consists of a biological reactor integrated with membranes that combine clarification and filtration of an activated sludge process into a simplified, single step process. Operating as an MBR allows conventional activated sludge plant...
