An overview of burst, buckling, durability and corrosion analysis of lightweight FRP composite pipes and their applicability

© 2019 Elsevier Ltd. All rights reserved.The main aim of this review article was to address the performance of filament wound fibre reinforced polymer (FRP) composite pipes and their critical properties, such as burst, buckling, durability and corrosion. The importance of process parameters concerning merits and demerits of the manufacturing methods was discussed for the better-quality performance. Burst analysis revealed that the winding angle of ±55° was observed to be optimum with minimum failure mechanisms, such as matrix cracking, whitening, leakage and fracture. The reduction of buckling effect was reported in case of lower hoop stress value in the hoop to axial stress ratio against axial, compression and torsion. A significant improvement in energy absorption was observed in the hybrid composite pipes with the effect of thermal treatment. However, the varying winding angle in FRP pipe fabrication was reported as an influencing factor affecting all the aforementioned properties. Almost 90% of the reviewed studies was done using E-glass/epoxy materials for the composite pipe production. By overcoming associated limitations, such as replacing synthetic materials, designing new material combinations and cost-benefit analysis, the production cost of the lightweight FRP composite pipes can be decreased for the real-time applications.Peer reviewe

Music effects on event-related potentials of humans on the basis of cultural environment

Auditory oddball responses were recorded from Turkish subjects in a silent environment or superimposed on white noise, or music played with violoncello or a similar music played with ney, a reed flute frequently listened by the Turkish population. P3 amplitudes with ney music in the background were significantly larger than both the white noise and violoncello backgrounds, The topography of the P3 response changed significantly between the ney and silent background conditions, indicating a relatively higher participation of frontal areas during hearing ney. Our results showed that hearing music of a familiar style increases the allocation of attentional resources during memory updating processes which is supposed to determine the P3 amplitude, and therefore showed the effects of cultural environment on the cognitive processes.

Systemic Phaeohyphomycosis due to Exophiala (Wangiella) in an Immunocompetent Child

We report a rare case of systemic lymphadenitis and hepatic involvement due to Exophiala (Wangiella) dermatitidis in a pediatric patient. An 8-year-old immunocompetent boy with chronic fever was examined through the use of sonography and CT scan which demonstrated cervical and mesenteric lymph node enlargement and numerous small hepatic lesions. The etiologic agent was isolated by means of lymph node aspiration. The fungus was identified by its morphological characteristics and through DNA sequencing of the internal transcribed spacer region of rDNA. Despite initial amphotericin B and voriconazole therapy, the child's jaundice subsided and he died 7 months later. In addition to pathogenic aspects of Exophiala dermatitidis, the diagnostic approaches and relevant therapeutic strategies are discussed.WoSScopu
