We demonstrate a ball-lens based optical interface for coupling between single mode fiber and silicon grating coupler from the back side of photonic integrated circuit (PIC). This allows compact packaging solutions keeps PIC top accessible, e.g. interacting with environment in case sensing applications. Different configurations employing 300 μ m diameter ball lenses made both LASF-35 glass sapp...

INTRODUCTION The advantages of fibre posts over stainless steel posts have been demonstrated in numerous studies. For clinical success, various factors need to be taken into account in post-retained restorations. MATERIAL AND METHODS A review was made of literature on fibre posts published from 2000 to February 2011, identified through searches of the PubMed/Medline databases. RESULTS The p...

Nanoindentation refers to a class of experimental techniques where micrometric force probe is used quantify the local mechanical properties soft biomaterials and cells. This approach has gained central role in fields mechanobiology, design tissue engineering, obtain proper characterization materials with resolution comparable size single cells (μm). The most popular strategy acquire such data e...

AIM To investigate the load capability of root filled teeth restored with glass fibre posts when the same self-adhesive composite resin cement was used as post cement and core build-up material. METHODOLOGY Human maxillary central incisors were divided into four groups (n=10). Teeth were root filled, decoronated and restored using glass fibre posts luted with different cements and composite r...
