nanofiltration (nf) has become a widely accepted process not only for producing drinking water but also for recovering wastewater in industrial processes or removing pollutants from industrial wastewater effluent. in the textile industry, the treatment of various dye baths with nf at room temperature have already been studied and was found feasible at lab-scale and pilot scale. the aim of this ...

Introduction Previous research has indicated that fluid choice is an important component of the resuscitation of the critically-ill patient. Synthetic hydroxyethyl starches (HES) may remain within the intravascular space compared to crystalloid solutions, yet they have also been associated with acute kidney injury. Data comparing HES and crystalloid solutions in anesthesia is incomplete. The go...

Efficient processing of top-k queries on multidimensional grids is a common requirement in information retrieval and data mining, for example in OLAP cubes. We introduce a data structure, the K-treap, that represents grids in compact form and supports efficient prioritized range queries. We compare the K-treap with state-of-the-art solutions on synthetic and real-world datasets, showing that it...
