Using a very recently proposed theoretical model, electron transfer rates in solution are calculated from first principles for different donor-acceptor pairs tetrahydrofuran. We show that this approach, which integrates tunneling effects into classical treatment of solvent motion, is able to provide reliable rate constants and their temperature dependence, even the case highly exergonic reactio...

Abstract The mediastinum is known as the anatomical structure connecting two pleural sacs. A variety of structures, from organs to veins and arteries, make mediastinal pathology extremely adventurous. We submit case a 67-year-old female patient, former smoker, who presented our clinic with dyspnoea on slight exertion, anterior chest pain ineffective cough. alarming aspect stridor present at reg...
