Anisotropy in Dry‐Type Valve‐Side Bushings of Converter Transformer: Phenomena and Effects
High Voltage, EarlyView.ABSTRACT The safe and stable working of dry‐type valve‐side bushings, important components of converter transformers, is essential. In recent years, poor design has led to several core breakdown, flashover and cracking failures. The bushing cores, composed of crepe paper and aluminium foil, exhibit significant anisotropic physical properties due to its

Boreas, EarlyView.Map of Lower sediment (LS) thickness is a surrogate for the distribution of Thorncliffe Formation (TF) and ~75% of TF thickness from the slope of Niagara Escarpment east to Brighton. Inset images show the LS sequence at the Don Valleys brickyards (DVBY) and undeformed TF sand and gravel (~15 m) below Newmarket Till (NT) at sites L and Co.

Uncertainty in stretch extrapolation of laminar flame speed from expanding spherical flames
Proceedings of the Combustion Institute, 2015 Abstract The present work investigated the uncertainties associated with the extrapolation of stretched flames to zero stretch in flame speed measurements using expanding spherical flames. Direct numerical simulations of time evolution of expanding spherical flames from a small ignition kernel to a propagating front with sufficiently large radius ...

Dental Traumatology, EarlyView.ABSTRACT Background/Aim Bi‐colored mouthguards (MTG) are often sought by both professional and amateur athletes. Bi‐colored MTG can be made in the dental office from premanufactured bi‐colored EVA sheets or custom‐designed in the dental office for greater color variety.

Journal of Sleep Research, EarlyView.ABSTRACT The mouse sleep is mostly recorded with only epidural electrodes and divided simply into NREM and REM stages. With the help of distributed intracerebral triplet electrodes, we searched for possible new electrophysiological signatures to characterise more specific sleep substages within the timeframe of seconds to tens of minutes.

Species‐Specific Vulnerability of Northern Red Sea Mesophotic Corals to Accelerated Warming
Global Change Biology Communications, Volume 1, Issue 2, June 2026.Mesophotic reefs are often considered climate refuges, yet experimental thermal‐stress reveals species‐dependent vulnerability. Skeletal optics, energy reserves, and light environment determine bleaching severity. A depth‐generalist coral resisted stress while the mesophotic specialist bleached severely.

Premixed CH-Air Flame Structure Characteristic and Flow Behavior Induced by Obstacle in an Open Duct
Advances in Mechanical Engineering, 2015 To study the fuel gas combustion hazards, the methane/air flame structure and flow characteristic in an open duct influenced by a rectangular obstacle were explored by experiment and realizable k -∊ model (RKE).

Laser induced spark ignition of methane-oxygen mixtures [PDF]
Results from an experimental study of laser induced spark ignition of methane-oxygen mixtures are presented. The experiments were conducted at atmospheric pressure and 296 K under laminar pre-mixed and turbulent-incompletely mixed conditions.
