The investigation of poly(butylene-2,6-naphthalate) crystallization by means of chip-calorimetry and ultrafast wide-angle X-ray diffraction (WAXD) revealed the existence of two possible mechanisms. The formation of the stable triclinic α-phase occurs directly from the undercooled melt at low cooling rates/high crystallization temperature. At higher cooling rates a two-stage route is observed: crystallization is preceded by the formation of a mesomorphic phase from the isotropic melt.

Background: Non-invasive positive pressure ventilation (NIPPV) is an effective treatment for acute respiratory failure in patients with chronic obstructive pulmonary disease. We assessed the efficacy and safety of this therapy in acute cardiogenic pulmonary edema (ACPE).
Methods: In addition to routine therapy consisting of oxygen, nitrates and diuretics, 60 patients (39 male, 21 female, mean age 72.
