an airlift-type activated sludge reactor using a sponge support medium was fed with wastewater containing 500 mg-n/l of nh4 +-n. in order to establish partial nitrification, the reactor was kept at 35°c. moreover, the reactor was started up with the nahco3 solution as an alkali agent to supply inorganic carbon for enhancement of partial nitrification. the partial nitrification was established d...

Magnetic nanoparticles are a highly valuable substrate for the attachment of homogeneous inorganic and organic containing catalysts. This review deals with the very recent main advances in the development of various nanocatalytic systems by the immobilisation of homogeneous catalysts onto magnetic nanoparticles. We discuss magnetic core shell nanostructures (e.g., silica or polymer coated magne...

This is a somewhat curious little book which was intended to be a concise note-book for medical, dental and other students to give them a brief idea of the subject before they attend their lectures and practical classes. It is no doubt a novel and ingenious idea on which the author may be congratulated. Blank pages have been put in so that students may draw diagrams from what they actually see ...

Copper indium sulfide, CuInS2 (CIS), has entered the field of photovoltaic cells for about three decades but somehow, they have not met their theoretically predicted efficiency as an absorber material. However, it is being employed a hole transport layer in conjunction with organic–inorganic perovskite solar cells, which offer improved environmental stability at reduced production cost. This co...

By employing (1)H NMR spectroscopy and molecular simulations, we provide an explanation for recent observations that the aqueous solubilities of ionic liquids exhibit salting-out to salting-in regimes upon addition of distinct inorganic salt ions. Using a typical ionic liquid [1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide], we observed the existence of preferential specific inte...

Using a dataset of over 1.9 million messages posted on Twitter by about 25,000 ISIS members, we explore how ISIS makes use of social media to spread its propaganda and to recruit militants from the Arab world and across the globe. By distinguishing between violence-driven, theological, and sectarian content, we trace the connection between online rhetoric and key events on the ground. To the be...
