Au-delà du rêve

open access: yesSwiss Journal of Sociocultural Anthropology, 2018
Based on an ethnography of affects within an Aboriginal support group in the Redfern suburbs (Sydney), I question the socio-psychological situation of the Aborigines in contemporary Australia as they face many difficulties in their everyday life. I show

La résilience du Rwanda aux chocs des années 1990 : Une perspective démographique [PDF]

open access: yes, 2014
Le Rwanda est un des pays Africains qui a le plus souffert des crises politiques depuis l’indépendance, surtout au cours de la décennie 1990-1999, culminant avec le génocide de 1994.

Multimodal Mechanical Testing of Additively Manufactured Ti6Al4V Lattice Structures: Compression, Bending, and Fatigue

open access: yesAdvanced Engineering Materials, EarlyView.
In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting

Renforcement de la résilience par un apprentissage post-crise : étude longitudinale sur deux périodes de turbulence

open access: yes, 2009
Les recherches sur les crises ont beaucoup étudié la prévention et la gestion des crises qui permettent à l'organisation d'absorber le choc et ainsi de faire preuve de résilience.

Can Ti‐Based MXenes Serve as Solid Lubricants for Brake Applications? A Tribological Study

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores the first implementation of Ti‐based MXenes materials in brake pad friction composite material. The resulting composite material exhibits a 48% reduction in the wear rate; alongside significant improvements are observed for thermal and mechanical properties.

Inflammatory Response‐Inspired Thermochromic Shield for Pneumatic Structures

open access: yesAdvanced Engineering Materials, EarlyView.
A thermochromic shield for pneumatic structures is developed, using anhydrous sodium acetate powder and thermochromic pigment‐included solution. In this shield composed of three layers, the exothermic and thermochromic reactions, followed by the mixture of both components, occur promptly with an incident of penetrating damage as a sign of initial ...

Population of Nonmetallic Inclusions in Liquid High‐Silicon Electrical Steel in Contact With MgO–C Refractories Based on Recyclates and Environmentally Friendly Binders

open access: yesAdvanced Engineering Materials, EarlyView.
The formation of nonmetallic inclusions (NMIs) was investigated in this study, carrying out immersion tests for 30 min at a temperature of 1600°C with liquid high‐silicon electrical steel (Si ≈ 3 mass‐%) and different MgO–C refractories. Conventional MgO–C refractories were considered, as well as MgO–C refractories containing MgO–C recyclate and ...
