Due to the increase in the number of vehicles, transportation management is achieved through the construction of bridges.This article discusses the vibrational effect in the design of bridges.In the structural design of the bridges proper planning is necessary, as gusts may occur, leading 8RR to aeroelastic instabilities.In this article a typical b
The effects of changing 90 mm and 110 mm plate spacings and FR factor of 0.9 kg/h, 1.3 kg/h, 1.7 kg/h, 1.9 kg/h on the total heat transfer performance and PD in the new design HX were examined.The results obtained by taking into account the change in plate spacing and FR factor of 0.9 kg/h, 1.3 kg/h, 1.7 kg/h and 1.9 kg/h, as well as variable facto
Enhanced dielectric and mechanical properties of polyarylene ether nitrile (PEN) are obtained through secondary dispersion of VGA polyaniline functionalized barium titanate (PANI-f-BT) by hot-stretching.PANI-f-BT nanoparticles with different PANI content are successfully prepared via in-situ aniline polymerization technology.The transmission electr
The self-assessment basedon Annex A of the ISO 9004:2009 standard is a very practical diagnostic tool and also very powerful for capturing the image of the organization quickly.It enables to have answers to questions suchas: what are the strengths and weakness of our organization? Do we have Cake Fork adequate processes, resources and competencies
Neuroblastomas are sometimes associated with abnormal constitutional karyotypes, but the XYY karyotype has been rarely described in neuroblastomas.Here, we report a case of an esthesioneuroblastoma in a boy with a 47, XYY karyotype.A 6-year-old boy was admitted to our hospital because of nasal obstruction and palpable Shorts cervical lymph node, wh
