the aim of this study was to compare the efficacy of antireflux therapy with both conventional management and those with no treatment in children with chronic otitis media with effusion (come). in this prospective randomized clinical trial ninety children with come which lasted more than 3 months or more, documented by physical examination and type b tympanogram in at least one ear without clin...

Abstract High-power continuous-wave single-frequency Er-doped fiber amplifiers at 1560 nm by in-band and core pumping of a 1480 Raman laser are investigated in detail. Both co- counter-pumping configurations studied experimentally. Up to 59.1 W output 90% efficiency were obtained the fundamental mode linear polarization co-pumped case, while less power achieved counter-pumped setup for addition...

The reaction of [Co(III)(TPP)Cl] (TPP is the dianion of 5,10,15,20-tetra-phenyl-porphyrin) with an excess of 4-nitro-aniline in di-chloro-methane leads to the title compound, [Co(III)(C44H28N4)(C6H6N2O2)2]Cl·CH2Cl2. The Co(III) ion lies on an inversion centre and is octa-hedrally coordinated by two N atoms of the NH2 groups of the two 4-nitro-aniline trans-axial ligands and four pyrrole N atoms...

background: a few studies have investigated the effect of the activation mode of adhesive systems on bond strength of fi ber posts to root canal dentin. this study investigated the push-out bond strengths of a glass fi ber post to different root canal regions with the use of two adhesives with light- and dual-cure polymerization modes. materials and methods: in this in vitro study, 40 maxillary...

Community-based development has been criticized for its inadequate understanding of power relationships at the local level, which thus leaves room for elite capture. This paper compares and contrasts two case studies, both of which take power seriously in their institutional designs. The solar home system in Bangladesh, represents the ‘counter-elite’ approach and explicitly excludes local elite...

background and aim: the aim of this article was to critically discuss the clinical application of a cognitive behaviour therapy (cbt) protocol for the treatment of hyperacusis and its asso­ciated distress. methods: narrative review recent findings: reviewing the research lit­erature suggests that hyperacusis, anxiety and safety seeking behaviours may be linked. therefore, it seems reasonable to...
