Characteristics of rotating instability in a centrifugal blower with shrouded impeller
Nihon Kikai Gakkai ronbunshu, 2014 The Rotating instability, abbreviated to RI, in a centrifugal blower with shrouded impeller is investigated by experiments and CFD analyses. The RI occurs in a partial-flow operation of the blower prior to stall with mild fluctuations of impeller ...

The prediction of wake wash in the towing tank [PDF]
, 2008 The wash or ship-generated waves from high speed craft has become a common subject in research and development of marine transportation. Since some time now the wake wash of high speed craft has become a problem in particular on inland or confined ...

SN 2009ip and SN 2010mc as dual-shock Quark-Novae
, 2013 In recent years a number of double-humped supernovae have been discovered. This is a feature predicted by the dual-shock Quark-Nova model where a SN explosion is followed (a few days to a few weeks later) by a Quark-Nova explosion.

Bioinspired Tissue Transparency: Achieving Sclera‐to‐Cornea Transplantation
Advanced Science, EarlyView.A bioinspired decellularization‐compression‐locking tactic (DCLT) is developed to transform human sclerae into transparent corneal substitutes. These clear, robust, and pro‐regenerative substitutes are capable of repairing complex corneal injuries, including chemical burns, keratoconus, and penetrating wounds, demonstrating their clinical potential to ...

Peptide Sequence Programmed Piezoelectric Response by Supramolecular Self‐Assembly
Advanced Science, EarlyView.In this study, hydrophobic tripeptides are explored as building blocks for stable piezoelectric crystals. Tripeptides with phenylalanine at the central position self‐assembled into uniform, thermally stable crystals. Piezoresponse force microscopy reveals a high effective piezoelectric coefficient of 24.0 pC N−1, attributed to asymmetric molecular ...

Rail skates for fixing rolling stock on the station tracks. Ground tests
Вестник Научно-исследовательского института железнодорожного транспорта, 2016 Currently manual brake shoes on Russian railways are used to solve two main tasks: to adjust uncoupling speed at humps (hump shoes), and to fix the rolling stock on the railway tracks.

Advanced Science, EarlyView.This study establishes an electric field‐induced directional migration model using fluorescence tension probes to visualize microfilament forces and intracellular osmotic pressure dynamics in the electrotactic migration of breast cancer cells. This model delineates how electromechanical interactions among membrane potential, ion channels, OP, traction ...
