This study presents the design, implementation, and assessment of a combined passive active flow control technique with aim increasing aerodynamic performance fixed-wing Micro Air Vehicles (MAVs). Power consumption restrictions in MAVs support choice solutions such as use modified (tubercled) wing leading edge. strategy successfully allows to delay mitigate stall but detrimental effects are fou...

Exonuclease (exo) III was used as a probe of the Escherichia coli RNA polymerase (RNAP) ternary elongation complex (TEC) downstream border. In the absence of NTPs, RNAP appears to stall primarily in a post-translocated state and to return slowly to a pre-translocated state. Exo III mapping, therefore, appears inconsistent with an unrestrained thermal ratchet model for translocation, in which RN...

The objectives were to evaluate quantitative animal-based measures of sow welfare (lameness, oral stereotypies and reactivity to humans) under commercial farm conditions, and to estimate the influence of housing, sow parity and stage of gestation on the outcome of these measures. Across 10 farms, 311 sows were used. Farms differed in terms of housing design (pen v. stall), space allowance, floo...

This study employs a numerical simulation method that combines the plasma body force model based on electrostatics with Navier–Stokes equations to investigate coupling mechanism of flow fields induced by multistage dielectric-barrier discharge (MDBD) actuation. Compared conventional single-stage alternating-current DBD (AC-DBD) actuation, MDBD actuation provides higher intensity and larger cont...
