Abstract: The sludge production and settleability have been estimated experimentally in a completely mixed biofilm-activated sludge reactor (hybrid reactor). A steady-state hybrid reactor was run at different stages of suspended ...

Abstract: A steady state mathematical model is developed for describing the completely mixed biofilm–activated sludge reactor (hybrid reactor). The model is derived by simultaneously considering Monod kinetics expressions and Fickian’s ...

Abstract: This study focuses on the assessment of the spatiotemporal structure of ENSO variability and its winter climate teleconnections to North America in the Intergovernmental Panel on Climate Change?s (IPCC) Fourth Assessment ...

Abstract: ajor volcanic events with a high loading of stratospheric aerosol have long been known to cause cooling, but their impact on precipitation has only recently been emphasized, especially as an analog for potential geoengineering ...

Abstract: The waste slurry generated in fertilizer plants in India has been converted into a cheap carbonaceous adsorbent material. This product is a promising scavenger of some toxic metal ions and phenols in industrial effluents. ...

Abstract: The spatio?temporal variability of precipitation over the United States using a 30-yr, gridded hourly precipitation dataset is studied. Orthogonal wavelet transform is applied to the time series at each grid box to capture ...

Abstract: The stationary wave response to global climate change in the Geophysical Fluid Dynamics Laboratory's R30 coupled ocean?atmosphere GCM is studied. An ensemble of climate change simulations that use a standard prescription ...

Abstract: This work addresses the magnetic and radiation effects on the fully developed mixed convective flow in a vertical channel occupied by a porous medium with the thermal nonequilibrium state. The assumption that the fluid is ...

Abstract: A direct and simple method is presented for the determination of sewer geometry of circular and noncircular shapes for partly full‐flowing conditions with the known variables being discharge, bed slope, and Mannings roughness ...
