Abstract Unsteady aerodynamic phenomena appearing close to the stall boundary in axial fans and compressors have been subject of extensive investigations. A particular phenomenon known as “rotating instabilities” typically occurs tip region at highly loaded conditions is often linked blade vibrations. During rig engine testing, it usually identified by characteristic shape its pressure spectra....

Chemical vapor deposition (CVD) is one of the best methods to grow graphene. In this way, there are many produce graphene by liquid and solid precursor. research, we grew using ethanol cyclohexane as precursors some these obtain method enter precursor furnace. We compare size domains investigate quality their products. As method, should keep inert gas into container dilute heat be sure that in ...

The mechanism of import-competent precursor protein-induced inactivation of a 50-pS anion channel of the chloroplast envelope is investigated using single-channel recordings. The inactivation by precursor protein is the result of the induction of a long-lived closed state of the channel. The mean duration of this state does not depend on precursor concentration. From this it can be concluded th...
