(Na0.8,K0.2)0.5Bi0.497Eu0.003TiO3 (NKBET20) piezoelectric ceramic powders were prepared by the solid-reaction method. The phase structures of the NKBET20 powders under various pressures were investigated by photoluminescence (PL) spectra and X-ray diffraction (XRD). The PL spectra of the doped Eu3+ ions suggest a pressure induced transformation…[Read more]

To optimize the diffusion-weighting b values and postprocessing pipeline for hybrid intravoxel incoherent motion diffusion kurtosis imaging in the head and neck region.

Optimized diffusion-weighting b value sets ranging between 5 and 30 b values were constructed by optimizing the Cramér-Rao lower bound of the hybrid intravoxel incoherent…[Read more]

ques. However, the superiority of piezosurgery in terms of nasal airflow, olfactory functions and quality of life were not found in the long term.Disabled child, care and ethical aspects. The child’s doctor occupies a privileged place in the life of a child with a disability. At all times, he must be an adviser, favouring a global approach and…[Read more]
