This paper investigates axial compression process of multi-layered tubes with circular cross-section under the axial loading in the quasi-static condition using experimental method. Some specimens are prepared in seven different groups, namely; empty carbon/epoxy composite tubes, solid carbon/epoxy composite rods, empty copper tubes, composite tubes with silicon sealant filler, concentrically s...

Abstract This paper describes the steps taken to improve measurement speed of a combined low-coherence and confocal refractive index system. The instrument measures thickness transparent plates using fibre-based interferometer with line-scan spectrometer. spectrometer allows on-line dispersion which is necessary derive sample t as well both phase group indices np, ng. measurements were performe...

Introduction Lead-based shields are the most widely used attenuators in X-ray and gamma ray fields. The heavy weight, toxicity and corrosion of lead have led researchers towards the development of non-lead shields. Materials and Methods The purpose of this study was to design multi-layered shields for protection against X-rays and gamma rays in diagnostic radiology and nuclear medicine. In this...
