We present a case of an eleven-year-old boy presenting with progressive extrapyramidal signs and dementia.His imaging findings demonstrated the classic eye-of-the-tiger sign on T2W magnetic resonance Concealer imaging.He was diagnosed with pantothenate kinase-associated neurodegeneration (PKAN).This is a rare autosomal recessive inborn error of coe
In adjustment of geodetic and photogrammetric networks, the surveying engineer faces many problems, such as errors of blunder Battery nature in the observations (when comparing the homogeny of precision) make these observations odd from the result, and effecting directly on observation values after adjustment, and the statistical results after anal
Fast and Course a pied - Femme - Vetements - Short - Cuissard local probes, such as X-ray spectroscopy, X-ray diffraction (XRD), and X-ray microscopy, have provided direct evidence for nanoscale phase separation in high temperature perovskite superconductors composed of (i) free particles coexisting with (ii) Jahn Teller polarons (i.e., charges ass
In order to quantitatively characterize the surface physical structure of a bundle of carbon fibers, scanning electron microscope (SEM) was used to photograph the fiber section and edge differential detection method was used to automatically identify the fiber boundary.By finding the smallest circumscribed convex polygon of fiber section and the mi
