We read with enthusiasm the article by John L. Semple on microvascular augmentation of single pedicle TRAM flap. As one reads the previously published articles on the microvascular augmentation of TRAM flaps, it is easily noticed that there is no clear concensus on the nomenclature of the method of vascular augmentation.

Design of a Tandem Compressor for the Electrically-Driven Turbocharger of a Hybrid City Car
Within a broader national project aimed at the hybridization of a standard city car (the 998 cc Mitsubishi-derived gasoline engine of the Smart W451), our team tackled the problem of improving the supercharger performance and response.
