Journal of the Royal Anthropological Institute, EarlyView.Our understanding of the recolonization of northwest Europe in the period leading up to the Lateglacial Interstadial relies heavily on discoveries from Gough's Cave (Somerset, UK). Gough's Cave is the richest Late Upper Palaeolithic site in the British Isles, yielding an exceptional array of human remains, stone and organic artefacts, and butchered ...

Closeness and disappointment in Jordanian friendships Proximité et déception en amitié en Jordanie
Journal of the Royal Anthropological Institute, EarlyView.Western folk models of friendship assume that friends like one another, implying mutually positive feelings. However, accounts of friendship from across times and places suggest that disappointment goes along with friendship as often as mutual affection.

Conducting Wall Hall Thrusters
IEEE Transactions on Plasma Science, 2015A unique configuration of the magnetic field and channel geometry near the wall of Hall thrusters, called magnetic shielding, has recently demonstrated the ability to significantly reduce the erosion of the boron nitride (BN) walls and extend the life of Hall thrusters by orders of magnitude.

Plasma oscillations in Hall thrusters
Physics of Plasmas, 2001The nature of oscillations in the 1 kHz–60 MHz frequency range that have been observed during operation of Hall thrusters is quantitatively discussed. Contours of various plasma parameters measured inside the accelerating channel of a typical Hall thruster are used to evaluate the various stability criteria and dispersion relations of oscillations that
