A virtual flight test is the process of flying an aircraft model inside a wind tunnel in a manner that replicates free-flight.In this paper, a 3-DOF aircraft-manipulator system is SPORT PROTEIN BERRY proposed that can be used for longitudinal dynamics virtual flight tests.The system consists of a two rotational degrees-of-freedom manipulator arm wi
A synthetic system links FeFe-hydrogenases to essential E. coli sulfur metabolism
Abstract Background FeFe-hydrogenases are the most active class of H2-producing enzymes known in nature and may have important applications in Intermittent Pre-Lubricated Catheters clean H2 energy production.Many potential uses are currently complicated by a crucial weakness: the active sites of all known FeFe-hydrogenases are irreversibly inactiva
