Various methods have been recommended to decide a proper insertion depth of central venous catheter (CVC). The carina is recommended as a useful target level for the CVC tip position. We evaluated the sternal head of a right clavicle and the nipples as anatomic landmarks for determining the optimal depth of CVC in paediatric patients. Ninety children, <5 yr, undergoing catheterization through...
We present the molecular beam epitaxial growth of nanocomposites consisting of semimetallic ErAs nanoparticles which are epitaxially embedded within InGaAlAs-based semiconductors. The properties of nanocomposites can be drastically different from that of the constituents, and in this case, the incorporation of ErAs is used to increase the thermoelectric power factor and decrease the lattice thermal...
