Guesting: rethinking the relationship between hospitality and homemaking within temporary refugee accommodation Le concept de guesting: repenser la relation entre hospitalité et création d'un « chez‐soi » dans l'hébergement temporaire des personnes réfugiées

Journal of the Royal Anthropological Institute, EarlyView.
This paper introduces the emic concept of guesting, coined by women living in refugee accommodation to distinguish their form of hospitality from other more hierarchical forms of hosting. Central to guesting is the unspoken rule that once you have played the host, next time you must be the guest.

Impact of Diagenetic Alterations on the Petrophysical and Multiphase Flow Properties of Carbonate Rocks Using a Reactive Pore Network Modeling Approach Impact des altérations diagénétiques sur les propriétés pétrophysiques et d’écoulement polyphasique de roches carbonates en utilisant une modélisation par l’approche réseau de pores

Oil & Gas Science and Technology, 2012
Sedimentary reservoir rocks generally have complex and heterogeneous pore networks that are related to the original depositional rock texture and subsequent diagenetic alterations. Such alterations are in part controlled by the original mineralogy and

Towards an anthropology of acquisition: ‘How did you get that?’ Vers une anthropologie de l'acquisition : « Où as‐tu trouvé ça ? »

Journal of the Royal Anthropological Institute, EarlyView.
The production‐distribution‐consumption triad has structured how anthropologists understand exchange for roughly a century. This article argues for expanding this triad to include an explicit focus on acquisition – the systems, processes, and practices of acquiring.

Laboratory study on the effects of hydraulic and granulometric parameters on the response of granular soil to internal erosion [PDF]

, 2019
Erosion is a major environmental problem to agricultural land as well as to civil engineering infrastructures. Rainwater infiltration into granular soils can lead to the migration of fine particles by suffusion.

Effect of combining a DC bias current with an AC transport current on AC losses in a High Temperature Superconductor

, 1998
Creating complex flux configurations by superposing a dc current or magnetic field onto the ac current in a type II superconducting tape should lead to a variety of peculiar behaviors.

Plant Variety Registration in Transition: Opportunities for Innovation and Reform in The European Union Enregistrement des variétés végétales en transition : opportunités d’innovation et de réforme dans l’Union européenne Die Registrierung von Pflanzensorten im Wandel: Chancen für Innovation und Neugestaltung in der Europäischen Union

EuroChoices, EarlyView.
Summary Modernising the European Union’s plant variety registration system is critical to enabling the development and adoption of sustainable, climate‐resilient varieties aligned with the EU Farm‐to‐Fork Strategy. However, the current system is outdated and under increasing pressure. While legislative reform is underway, key points of divergence among
