assessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

متن کاملRemoval of Pharmaceutical Products in a Constructed Wetland
Background: There is growing interest in the natural and constructed wetlands for wastewater treatment. While nutrient removal in wetlands has been extensively investigated, information regarding the degradation of the pharmaceuticals and personal care products (PPCPs) has only recently been emerging. PPCPs are widely distributed in urban wastewaters and can be removed to some extent by the con...
متن کاملConstructed Wetland Treatment of Nitrates: Removal Effectiveness and Cost Efficiency
A constructed wetland (CW) was strategically placed to treat nitrates in groundwater as part of a watershed-based farmer engagement process. Using stream water quality data collected before and after installation, this CW was found to reduce stream concentrations of nitrogen from nitrate (NO3-N) during the growing season by about 0.14 mg/l at mean streamflow, a 17% reduction. Based upon realist...
