the purpose of this study is to investigate the accuracy of predictions of aniline removal efficiency in a moving bed biofilm reactor (mbbr) by various methods, namely by rbf, anfis, and fuzzy regression analysis. the reactor was operated in an aerobic batch and was filled by light expanded clay aggregate (leca) as a carrier for the treatment of aniline synthetic wastewater. exploratory data an...

Sorption of phosphorus (P) to the bed sand medium is a major removal mechanism for P in subsurface flow constructed wetlands. Selecting a sand medium with a high P-sorption capacity is therefore important to obtain a sustained P-removal. The P-removal capacities of 13 Danish sands were evaluated and related to their physico-chemical characteristics. The P-removal properties of sands of differen...

The emergence of the nucleus was a major event of eukaryogenesis. How the nuclear envelope (NE) arose and acquired functions governing chromatin organization and epigenetic control has direct bearing on origins of developmental/stage-specific expression programs. The configuration of the NE and the associated lamina in the last eukaryotic common ancestor (LECA) is of major significance and can ...

Trachyandra divaricata (Sandkool) is one of the most abundant wild edible inflorescence vegetables in South Africa. The dearth literature on its edibility, nutrient composition, and conservation has contributed to underutilisation. This study investigated mineral proximate content, phytochemical compositions, growth response T. light intensity soilless media. Treatments comprised four media (LE...

The galactose specific lectin LecA partly mediates the formation of antibiotic resistant biofilms by Pseudomonas aeruginosa, an opportunistic pathogen causing lethal airways infections in immunocompromised and cystic fibrosis patients, suggesting that preventing LecA binding to natural saccharides might provide new opportunities for treatment. Here 8-fold (G3) and 16-fold (G4) galactosylated an...

Constructed wetlands (CWs) are important plant filters used for wastewater treatment. The behavior of the Canna indica-planted CWs in face a highly variable composition industrial has yet to be understood. Here, we show effectiveness and unplanted vertical subsurface flow treatment Algiers petroleum refinery’s effluent. selected species was placed containing light expanded clay aggregate (LECA)...

For many years, lightweight concretes (LWC) have been utilized successfully in the construction of buildings because their low specific weight, high thermal insulation capacity, and sound insulation. The development that led to self-compacting concrete (LWSCC) is a significant step forward recent years. These chains concrete's beneficial properties with concrete. purpose this experimental inves...
