In this paper a new topology is introduced for three-phase inverter that includes a multi-level module, a three-phase inverter bridge and middle levels selection unit. The main advantage of proposed topology is using fewer switches and diodes to reach the maximum level of output voltage. The structure consists of a single-phase multilevel module; three bidirectional switches and a three-phase i...
Introduction: The causal dynamics between environment, health expenditures and economic growth has recently started to be studied in the economics literature for both developing and developed countries. Methods: This study examines the causal relationship between CO2 emissions, health expenditures and economic growth using dynamic simultaneous-equations models for Iran over the period 1972-2...
OBJECTIVE To assess the impact of the bidirectional cavopulmonary shunt, total cavopulmonary connection, and baffle fenestration on outcome of the Fontan operation in our unit. METHOD We reviewed 123 bidirectional cavopulmonary shunts and 264 Fontan operations performed from 1980 to 1995. Analysis of pulmonary artery size (right and left main and lower lobe branches) before and after bidirect...
