A novel process configuration was designed to increase biofilm growth in tertiary moving bed reactors (MBBRs) by providing additional substrate from primary treated wastewater a sidestream reactor under different redox conditions order improve micropollutant removal MBBRs with low availability. This recirculating MBBR operated on pilot scale for 13 months, and systematic seen the biomass concen...

lengthy enrichment procedures in earlier studies. The highly sensitive and specific TEA (7) simplifies the quantitative deter mination of nitrosamines, in that these nonvolatile compounds need only be concentrated once prior to separation by HPLC and detection. For an accurate measurement of these nitrosamines in chew ing tobacco, tobacco leaves, and unaged smoke, extraction procedures as well ...

Endtidal carbon dioxide (ETCO2) is the measurement of CO2 in exhaled respiratory gases and serves as an estimate of arterial CO2. ETCO2 is measured by a capnograph in a mainstream or sidestream method. A no...

Sidestream cigarette smoke (SSCS) makes up about 85% of significantly toxic environmental tobacco smoke (ETS). Reactive oxygen species (ROS) in SSCS play an important role in the pathogenesis of a wide range of diseases. Interleukin-6 is a pro-inflammatory cytokine and is closely linked with pathology in cardiovascular disease and conditions that have an inflammatory base. Exposure to SSCS thro...
