Deformation and Failure Law of Roadway along Goaf and Reserve Width of Section Coal Pillar by Yunsheng Chen, Jian Sun, Di Pang, Ruofei Zhang

“…On this basis, the deformation failure law of 7 m and 8 m coal pillars and surrounding rock of roadway along goaf under different supporting conditions (bolt and cable with different row spacing) were further simulated and analyzed. The results showed that when 7 m coal pillars were reserved in 9106 roadway along goaf, the optimal bolt row spacing was 800 mm. …”

Jardins imaginaires en partage by Cécile Regnault, Magali Paris

“…The approach privileges the shared construction of imaginary spaces. Based on the analysis of the representations produced by students, our perspective as researchers demonstrates how these imaginary spaces are not confined to the virtual world but are situated somewhere between design and production and rely on a form of imagination which focuses on creating rather than reproducing.…”

Life on board ship and cultural intimacy. Notes from the Central Mediterranean by Jasmine Iozzelli

“…When they meet aboard seagoing vessels, these currents construct a highly diverse range of shared spaces.Exploring both the macro-structure and some of the micro-practices that constitute these spaces, I attempt to point up some of the contradictions – between humanitarian logic and activist demands, between efficiency and processes of dehumanization, between formal rationality and the unpredictability of events – that arise in the construction of a sense of belonging on board a large SAR ship.…”
