Bi-stability resistant to fluctuations

, 2017
We study a simple micro-mechanical device that does not lose its snap-through behavior in an environment dominated by fluctuations. The main idea is to have several degrees of freedom that can cooperatively resist the de-synchronizing effect of random ...

Influence of the axial fan blade angle on the turbulent swirl flow characteristics [PDF]

Scientific Technical Review, 2014
The paper presents the investigation of the turbulent swirl flow in a pipe behind the axial fan with adjustable nine blades for the angles of 22°, 26° and 30° for the same rotation number (1500 rpm). Velocities were measured with laser Doppler anemometry

A histidine‐rich extension of the mitochondrial F0 subunit ATP6 from the ice worm Mesenchytraeus solifugus increases ATP synthase activity in bacteria

FEBS Letters, EarlyView.
The glacier ice worm Mesenchytraeus solifugus survives year‐round at 0 °C. Its ATP6 subunit, which forms a regulatory component of the proton pore in mitochondrial ATP synthase, has a carboxy‐terminal extension not found in any other organism examined to date. Here, we show that fusion of this extension to the homologous AtpB protein in E. coli results
