Correlated Transient Response of Buried Cables and Lightning Channel Radiation of Return Strokes of Five Rocket‐Triggered Lightning Strikes

High Voltage, EarlyView.
ABSTRACT Data from five rocket‐triggered lightning flashes are adopted to analyse the correlated transient response of buried cables and lightning channel radiations. These five flashes have the same termination point that is right above the buried cables and involve a total of 32 return strokes.

Direct lightning strikes to the lightning protective system of a residential building: triggered-lightning experiments [PDF]

IEEE Transactions on Power Delivery, 2002
Summary form only given. Lightning triggered from natural thunderclouds using the rocket-and-wire technique was employed in order to subject to direct lightning strikes the lightning protective system of a test house at the International Center for Lightning Research and Testing (ICLRT) at Camp Blanding, Florida, USA. The electrical circuit of the test

Absolute scaling of small‐ and wide‐angle X‐ray scattering images recorded with short duration X‐ray pulses on a large area fiber‐taper X‐ray detector

Journal of Synchrotron Radiation, EarlyView.
An X‐ray scattering setup designed to capture small‐ and wide‐angle X‐ray scattering on a single, large area detector features a partially transmissive beamstop that facilitates non‐invasive recording of X‐ray beam position and intensity during acquisition of X‐ray scattering images.

Punchline with(out) purpose: Integrating research on instructional humour and seductive details

British Journal of Educational Psychology, EarlyView.
Abstract Introduction We integrated research on instructional humour and seductive details to investigate when affiliative course‐related humour is effective or rather ineffective for learning. We assumed that instructional humour without a cognitive function (irrelevant humour) would have detrimental effects on learning performance resembling the ...
