Dynamic Absorbers for Rotating Machinery

, 2015
Dynamic absorbers are simple passive devices installed on mechanical systems to absorb and dissipate kinetic energy, thus reducing the amplitude of vibrations/oscillations. The most widely spread typologies of dynamic absorbers belong either to the family of the Tuned Mass Dampers (TMD) and Tuneable Liquid Column Dampers (TLCD).

Observations of acoustic emission activity during gear defect diagnosis. [PDF]

, 2003
It is widely recognised that acoustic emission (AE) is gaining ground as a non- destructive technique (NDT) for health diagnosis on rotating machinery.

Calculation of Rotor Dynamic Coefficients for Labyrinth Seals

International Journal of Rotating Machinery, 1998
A single control volume, Iwatsubo based bulk flow method for the calculation of these coefficients is developed and implemented. The method herein uses a unique iterative technique to first identify the mass flow rate based on pressure drops across the ...

Targeting TNBC: core–shell polycationic polyurea dendrimers with inherent anticancer activity

FEBS Open Bio, EarlyView.
Core–shell polycationic PURE dendrimers were tested in TNBC‐derived tumor models. Both formulations selectively targeted TNBC and effectively reduced tumor volume. PUREG4‐OEI48 suppressed tumor growth without detectable toxicity, whereas PUREG4‐OCEI24, despite showing efficacy, induced hepatic toxicity.

Air brake-dynamometer accurately measures torque [PDF]

, 1965
Air brake-dynamometer assembly combines the principles of the air turbine and the air pump to apply braking torque. The assembly absorbs and measures power outputs of rotating machinery over a wide range of shaft speeds.

Detection of coupling misalignment by extended orbits [PDF]

, 2015
In this paper a ‘SpectraQuest’ demonstrator is used to introduce misalignment into a rotating machinery set-up. Depending on the coupling used in the set-up, angular and/or parallel misalignment can be brought in the rotating system.

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

FEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.
