In this work, the effectiveness of removing colour and total suspended solid (TSS) from complex organic particulate artificial sewage (COPAS) via coagulation process was studied. Organo-floc (OF), a tannin-based coagulant derived plant used as coagulant. OF applied in jar test experiment at various dosages 57 rpm for 5 min, 30 min sedimentation time to find out optimum dosage TSS removal. Zeta ...

The modulation of cyclic GMP metabolism by oxidativereductive-related processes was studied in intact guinea pig splenic cells and with respect to the activities of soluble and particulate guanylate cyclase. In intact cells the oxidant dehydroascorbic acid produced timeand concentration-dependent increases in cGMP steady state levels which were potentiated by the phosphodiesterase inhibitor 3-i...

The U.S. Environmental Protection Agency (EPA) performed an Information Collection Request (ICR) in 1999 to gather additional information on the control and emission of mercury from coal-fired power plants. The ICR data indicates that a significant, but highly variable, amount of mercury removal can occur across a power plant’s conventional air pollution control (APC) equipment used for the cap...

Cells of Escherichia coli selectively degrade proteins that have incorporated amino acid analogs. Within 1 hour after exposure of cells to canavanine, 50% of the analog-containing proteins were degraded to acid-soluble form. At the same time, no net loss of canavanine-containing protein occurred from the 100,000 X g supernatant. Instead, most of the proteins containing the analog, unlike normal...

Nature-based solutions have been identified by the European Union as being critical for the enhancement of environmental qualities in cities, where urban and peri-urban forests play a key role in air quality amelioration through pollutant removal. A remote sensing and geographic information system (GIS) approach was applied to the Metropolitan City (MC) of Rome to assess the seasonal particulat...

Broad-leaved evergreen trees create urban forests for mitigation of climate warming and adsorption particulate matter (PM). This study was performed to identify the species suitable greening by examining capacity in areas Korea, points elemental composition PM adsorbed tree. Leaf sampling carried out four times (period seven months from October 2017 May 2018) used after drying 28 37 days). Part...
