The release of untreated dye textile wastewater into receiving streams is unacceptable not only for aesthetic reasons and its negative impacts on aquatic life but also because numerous dyes are toxic and carcinogenic to humans. Strategies, as of now, used for treating textile wastewaters have technical and economical restrictions. The greater part of the physico-chemical methods, which are used...

in this study, zno nanoparticles were loaded on activated carbon prepared from almond shell (zno-np-ac). then, this novel material applied as an efficient adsorbent for the ultrasonic assisted simultaneous removal of basic blue 41(bb41) and basic red 46 (br46) in binary solution.  the efficiency of proposed activated carbon was enhanced by acid treatment and subsequent modification by physical ...

Major Guidelines Changes Changes in the pediatric section of the International Guidelines 2000 generally represent qualifications and refinements rather than major paradigm shifts from the 1992 Guidelines.1 The new guidelines continue to emphasize prevention of cardiac arrest. Pediatric BLS guidelines detail specific modifications of adult techniques necessary to address anatomic, physiological...

Our ability to see in bright light depends critically on the rapid rate at which cone photoreceptors detect and adapt to changes in illumination. This is achieved, in part, by their rapid response termination. In this study, we investigate the hypothesis that this rapid termination of the response in red cones is dependent on interactions between the 9-methyl group of retinal and red cone opsin...

The hemolytic process in hereditary spherocytosis (HS) is presumed to involve an intrinsic defect in the structure or metabolism of the red cell (1-3). The nature of the basic cellular defect remains enigmatic, although its manifestations are well characterized. Distinctive features of the HS red cell are its more spheroidal shape, small surface area, and high hemoglobin concentration and its e...

Let A be a partial *-algebra endowed with a topology τ that makes it into a locally convex topological vector space A[τ ]. Then A is called a topological partial *-algebra if it satisfies a number of conditions, which all amount to require that the topology τ fits with the multiplier structure of A. Besides the obvious cases of topological quasi *-algebras and CQ*-algebras, we examine several c...

Recent studies of QCD Green’s functions and their applications in hadronic physics are reviewed. We discuss the definition of the generating functional in gauge theories, in particular, the rôle of redundant degrees of freedom, possibilities of a complete gauge fixing versus gauge fixing in presence of Gribov copies, BRS invariance and positivity. The apparent contradiction between positivity a...
