Abstract This paper summarizes the emissivity measurements performed on plasma-facing units (PFU) of WEST lower divertor during first phase running with a mix actively cooled ITER-like PFUs made bulk tungsten (W) and inertially graphite coating tungsten. In situ assessments laboratory after removing W-coated ITER-grade from device are shown. The exhibit complex pattern strong variation as funct...

Abstract An earthquake sequence in the Storfjorden offshore area southwest of Spitsbergen Svalbard archipelago initiated with a 21 February 2008 magnitude Mw 6.1 event. This had previously not produced any significant earthquakes, but between and 2020, total ?2800 earthquakes were detected, ?16 them being moderate size (ML?4.0). Applying double-difference relocation to improve relative location...

The predatory labial strike of dragonfly (Aeschna) larvae could be elicited by an artificial water jet stimulus. The larvae showed fair prey-catching ability even when visually deprived, whereas when deprived of mechanosensory and visual information, the ability decreased sharply. Also, immobilized prey were unable to elicit a strike even from intact larvae. The percentage of labial strike (PLS...

Research concerning forefoot strike pattern (FFS) versus rearfoot strike pattern (RFS) running has focused on the ground reaction force even though internal joint contact forces are a more direct measure of the loads responsible for injury. The main purpose of this study was to determine the internal loading of the joints for each strike pattern. A secondary purpose was to determine if converte...

BACKGROUND Impulsive forces in the knee joint have been suspected to be a co-factor in the development and progression of knee osteoarthritis. We thus evaluated the impulsive sagittal ground reaction forces (iGRF), shock waves and lower extremity joint kinematics at heel strike during walking in knee osteoarthritis (OA) patients and compared them to those in healthy subjects. SUBJECTS AND MET...

Veterinary surgeons are sometimes asked to examine animals that have been found dead without premonitory signs. When death occurs in this manner and without explanation, the term ‘sudden unexpected (unexplained) death’ (SUD) is used.This does not necessarily imply that death was instantaneous, but is usually defined as the death of an animal that appears healthy but dies suddenly within a few m...

Ant-lions are pit-building larvae (Neuroptera: Myrmeleontidae), which possess relatively large mandibles used for catching and consuming prey. Few studies involving terrestrial arthropod larva have investigated prey capture behavior and kinematics and no study has shown modulation of strike kinematics. We examined feeding kinematics of the ant-lion, Myrmeleon crudelis, using high-speed video to...

To survive, organisms must avoid predation and acquire nutrients and energy. Sensory systems must correctly differentiate between potential predators and prey, and elicit behaviours that adjust distances accordingly. For snakes, strikes can serve both purposes. Vipers are thought to have the fastest strikes among snakes. However, strike performance has been measured in very few species, especia...
