The goal of this experiment is to evaluate the effectiveness of different leachate pre-treatment options in terms of COD and ammonia removal. This research focused on the evaluation of physical-chemical methods for pre-treatment of leachate that would be effective and rapid in order to satisfy the requirements of the sewer discharge by-laws. The four pre-treatment options evaluated were: air st...

BACKGROUND One of the most frequent reasons for failure of haemodialysis lines is catheter blockage caused by fibrin sheath formation. We report our experience of percutaneous fibrin sheath stripping in treating this problem. METHODS A consecutive series of failing haemodialysis catheters underwent percutaneous fibrin sheath stripping in an attempt to retrieve and prolong the life of the cath...

The preparation of highly pure vanadyl sulfate from sulfate solutions containing impurities of iron and aluminumwas investigated by solvent extraction with 2-ethylhexyl phosphoric acid mono-2-ethylhexyl ester (EHEHPA) and tri-n-butyl phosphate (TBP) as the phase modifier. The extraction and stripping conditions of vanadium (IV) and its separation from iron and aluminum were optimized. Under the...

This paper presents an unsupervised approach for the development of a stemmer (For the case of Urdu & Marathi language). Especially, during last few years, a wide range of information in Indian regional languages has been made available on web in the form of e-data. But the access to these data repositories is very low because the efficient search engines/retrieval systems supporting these lang...

Following the work of Austgen et al., the electrolyte nonrandom-two-liquid (NRTL) model was applied in a thermodynamically consistent manner to represent the vapor-liquid equilibrium (VLE) of the aqueous monoethanolamine (MEA)-CO2 system with rigorous chemical equilibrium consideration. Special attention was given to the accurate VLE description of the system at both absorbing and stripping con...

Monitoring Pb2+ contentin drinking water is an important measure to safeguard safety for residents. To overcome drawbacks available electrochemical sensors, this work attempts fabricate a boron-doped diamond (BDD) electrode detecting in water. A systematic investigation was conducted on microstructural and performances of BDD electrode. The results show that, grains arrange well surface. exhibi...

We investigate the role of ram pressure stripping in the Virgo cluster using N-body simulations. Radial orbits within the Virgo cluster's gravitational potential are modeled and analyzed with respect to ram pressure stripping. The N-body model consists of 10 000 gas cloud complexes which can have inelastic collisions. Ram pressure is modeled as an additional acceleration on the clouds located a...
