Flow–thermal analysis of ventilation and cooling capacity of centrifugal fans with splitter blades in high-voltage asynchronous motors [PDF]

open access: yesInternational Journal of Fluid Engineering
High-voltage asynchronous motors (HVAMs) face the problem of excessive internal temperatures during operation, which not only compromises operational safety, but may also shorten their service life.

Reversible, Chemically Gated FRET via Ligand‐Activated Acceptors

open access: yesAdvanced Science, EarlyView.
Fluorogen binding turns the compact FAST tag into a tunable FRET acceptor, with ligand chemistry programming spectral overlap and excited‐state lifetimes. Fluorescence‐lifetime imaging reads out energy transfer through the shortened donor lifetime, while simply adding or washing out the dye switches FRET on and off, reversibly mapping the supramodular ...

Macrophage Dab1 Links Early Hypoxia to Adaptive Angiogenesis to Drive Peripheral Nerve Repair

open access: yesAdvanced Science, EarlyView.
Schematic diagram illustrating the Dab1‐linked hypoxia signaling pathway that accelerates angiogenesis and consequent nerve regeneration. Following PNI, a hypoxic microenvironment develops. Hypoxia induces macrophage Dab1 phosphorylation, resulting in NHE‐1 upregulation, HIF‐1α stabilization, and VEGF‐A expression. This cascade promotes angiogenesis in

Palmitoyl Acyltransferase Zdhhc17 Promotes Functional Recovery After Spinal Cord Injury by Targeting the Nuclear Transport Factors Kpna2 and Ipo9

open access: yesAdvanced Science, EarlyView.
In this study, we demonstrate that Zdhhc17, acting as a PAT, suppresses neuronal apoptosis and promotes axon regeneration after injury, thereby enhancing functional recovery following SCI. In this context, Kpna2 and Ipo9 serve as novel palmitoylation substrates of Zdhhc17, whose palmitoylation prevents the injury‐induced degradation of their proteins ...

EFFECT OF MODE OF ROTATION AND SPEED ON THE PRESSURE FIELD AND AXIAL THRUST OF INDUSTRIAL CENTRIFUGAL FAN

open access: yesJournal of Engineering and Sustainable Development, 2016
Centrifugal fans are used widely in most of the manufacturing processes for ventilating and/or air conditioning the working areas. Because of relatively limited documentation on the design of this type of fans, experimental and theoretical works are ...

Simulation of Entropy Generation under Stall Conditions in a Centrifugal Fan

open access: yesEntropy, 2014
Rotating stalls are generally the first instability met in turbomachinery, before surges. This 3D phenomenon is characterized by one or more stalled flow cells which rotate at a fraction of the impeller speed. The goal of the present work is to shed some
