The use of constructed wetlands for purifying pre-treated wastewater is a cost effective technology that has been found to be more appropriate for many developing countries. The technology is also environmentally friendly with the wetlands being habitats for many water birds and other aquatic organisms. This study assessed nutrient removal efficiency of two floating macrophytes (Lemna minor...

PhanePhos-analogous phosphorous ligands have been generated via self-assembly through hydrogen-bonding, and studied in rhodium-catalyzed asymmetric hydrogenation (up to 99% ee).

Case A. A. 16 years old, female referred to our service for evaluation of hypercalcemia. The patient presented with fracture at the thoraco-lumbar spine after being accidentally slipped on the floor. She sought consult at a private hospital and an orhtopedic brace was applied. Three months after the incident, the patient complaint of limping and eventually with difficulty in ambulating. She was...

Coking resistance: In this work, RuP2-MoP catalysts are shown to be highly stable and selective in the dehydrogenation of long-chain alkanes like n-heptane. Furthermore, active transition metal phosphide is compared its phosphorous-free RuMo-counterpart. addition improving olefin selectivity, incorporation phosphorous into RuMo-surface structure avoids catalyst deactivation.

Freshwater macroalgae represent a largely overlooked group of phototrophic organisms that could play an important role within an industrial ecology context in both utilising waste nutrients and water and supplying biomass for animal feeds and renewable chemicals and fuels. This study used water from the intensive aquaculture of freshwater fish (Barramundi) to examine how the biomass production ...

Article Type: Full Length Research Article The aim of this investigation was to confirm a trickling filter filled with gravel as an alternative biological process over conventional high cost treatment process with regard to nutrient reduction from brewery wastewater. Steady state evaluation of the trickling filter aerobic and anaerobic biofilm system for nutrient removal was made. The results o...
