in this research, the effects of the addition of powdered activated carbon (pac) into the aeration zone of an activated-sludge (as) system for treating tehran oil refinery effluent, was investigated during more than 12 months in a pact pilot-scale model. besides the evaluation of organics removal efficiency and determination of basic design factors kinetic coefficients, a series of experiments ...

septicemia in neonates is the commonest cause of mortality. early recognition and diagnosis of neonatal sepsis remains a challenge because of the variable and nonspecific clinical presentation. the laboratory criteria are often non specific and not fully reliable. the objective of this review is to highlight the various hematological and biological markers of neonatal sepsis. we searched pubmed...

in recent years, demand for biological sensors which are capable of fast and accurate detection of minor amounts of pathogens inreal‑time form has been intensified. acoustic wave (aw) devices whose performance is determined by mass sensitivity parametersand quality factor are used in biological sensors as platforms with high quality. yet, current aw devices are facing many challengessuch as the...

Abstract Populus nigra ‘Italica’ (Lombardy poplar) is a breeding cultivar of black poplar, widely used as street tree or windbreak, often exposed to salinity and limited water availability. roots can develop dual mycorrhizal associations with ectomycorrhizal (ECM) arbuscular (AM) fungi, non-mycorrhizal fungal endophytes (FE). The symbiotic fungi may alleviate the effects adverse environmental c...

Introduction The National Key Ecological Functional Areas (NKEFAs) are location-oriented ecological engineering of China, which rely on the main functional area planning. co-benefits product supply and environment improvement NKEFAs has not been fully assessed in literature. Methods is considered a quasi-natural experiment, time-varying difference-in-differences (DID) model used to assess impac...
