introduction: dye removal from industrial wastewater has been considered as one of the most environmental issues. recently, new methods of treatment such as catalytic ozonation have been used to increase dye removal efficiency. so, the efficiency of catalytic ozonation by copper coated zeolite as a catalyst in the removal of reactive red 198 was investigated. materials & methods: in order to re...

3D rotation electron diffraction, Rietveld refinement and spherical aberration-corrected TEM reveal that Ni 0.22 V 2 O 5 (o-NiVO) possesses a novel framework with unsaturated Ni/V centers short ··· V/Ni distances, which shows high capacity, good rate capability long-term durability low Zn 2+ migration barrier. • O-NiVO distances. The structure of o-NiVO is confirmed by diffraction HAADF-STEM. o...

We analyze EU Regional Policy during four programming periods: 1989-1993, 1994-1999, 2000-2006, 2007-2013. When looking at all periods, we focus on the growth, employment and investment effects of Objective 1 treatment status. For the two later periods, we additionally look at the effects of the volume of EU transfers, overall and in sub-categories, on various outcomes. We also analyze whether ...

Background The 2010 rheumatoid arthritis (RA) classification criteria are intended for research purposes and of the disease not diagnostic purposes. It is however a tool which clinicians commonly use in everyday practice when evaluating patients with arthritis. clearly stated that synovitis should be better explained by another disease. However, some who classified as seronegative RA might stil...

The structure of β-molybdenum dichloride is compared with that of TcCl(2) using EXAFS spectroscopy. For TcCl(2), the Tc atom is surrounded by Tc atoms at 2.13(2), 3.45(3), 3.79(4), and 4.02(4) Å. For β-MoCl(2), the Mo is surrounded by Mo atoms at 2.21(2), 2.91(3), and 3.83(4) Å. The latter distances are consistent with the presence of an [Mo(4)Cl(12)] unit in the solid state, one constituted b...

Objective: Previous studies have examined the role of sensory nerves and neural mediators in symmetrical joint inflammation and autoimmunity in rheumatoid arthritis (RA). In this study, we sought to examine the association between capsaicin skin test and disease activity in RA patients. Materials and Methods: Eighty RA patients (case group) and 20 healthy volunteers were enrolled in this experi...
