"Aging behavior of fluororubber with high fluorine content in aviation lubricating oil"
High fluorine content fluororubber (FKM) was used as the research object, the high temperature medium resistance of high fluorine content FKM vulcanizates in a variety of aero-engine lubricanting oils was investigated, and the changes in physical and ...

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

Self-noise produced by an airfoil with nonflat plate trailing-edge serrations [PDF]
This paper represents the results of an experimental study aimed at reducing the airfoil self-noise by the trailing edge serration of four different sawtooth geometries (defined in the serration angle and length).

Non-linear viscoelastic characterization of perfluroelastomer raw rubber
Large-amplitude oscillatory shear (LAOS) tests were carried out on 1055 B and 2160 B perfluroelastomer raw rubber. The structural differences were explored by analyzing their rheological behavior.

Quadratic approach for single-channel noise reduction
In this paper, we introduce a quadratic approach for single-channel noise reduction. The desired signal magnitude is estimated by applying a linear filter to a modified version of the observations’ vector.

Noise Reduction of Spiral Ducts [PDF]
The paper presents noise reduction (NR) of spiral ducts as a result of computational modeling of acoustic wave propagation. Three-dimensional models were created with the finite element method in COMSOL Multiphysics version 3.3. Nine models of spiral ducts with 1-9 spiral leads were considered.

Experimental aeroacoustics study on jet noise reduction using tangential air injection [PDF]
PhDAircraft jet exhausts are a source of undesirable noise and continue to be an area of investigation driven by increasingly stringent regulation. The noise is produced by the unsteady mixing of the jet with the surrounding air and is dominated by the ...
