TEMPERATURE TRENDS OF THE PERMITTIVITY IN COMPLEX OXIDES OF RARE-EARTH ELEMENTS WITH PEROVSKITE-TYPE STRUCTURE

TEMPERATURE TRENDS OF THE PERMITTIVITY IN COMPLEX OXIDES OF RARE-EARTH ELEMENTS WITH PEROVSKITE-TYPE STRUCTURE

Ceramic materials based on complex oxides with both the Baseball perovskite structure (Ln2/3Nb2O6) and the structure of tetragonal tungsten bronze (Ba6-xLn8+2x/3Ti18O54) have been investigated over a wide frequency and temperature ranges.The results obtained for certain structures denote the presence of the temperature anomalies of dielectric param

Cortical stimulation in pharmacoresistant focal epilepsies

Abstract Pharmacoresistance and adverse drug events designate a considerable group of patients with focal epilepsies that require alternative treatments GANGSTA GRIP such as neurosurgical intervention and neurostimulation.Electrical or magnetic stimulations of cortical brain areas for the treatment of pharmacoresistant focal epilepsies emerged from
