Bodyrevolt, Lauren Oliver

Theses

BodyRevolt examines the body as a mutable site shaped through performance, material intervention, and photographic mediation. Working across still and moving image, I stage choreographic interactions between my body and constructed forms—materials that function as both extensions and substitutions—destabilizing the notion of a fixed bodily truth. Through acts of sculpting, contortion, and repetition, I explore the tension between the body I inhabit and the body I imagine, using the camera not simply as a recording device but as an active participant in rehearsing transformation. Central to this inquiry is the construction of surrogate bodies, which offer a form of control …

Dynamic Response Characteristics And Failure Mechanism Of Coal-Rock Combination Under Different Immersion Conditions, Zhang Xiangyang, Tong Zhipeng, Duan Yungang, Yang Weikun, Chen Jianben, Xu Linfeng

Coal Geology & Exploration

Background In practical engineering, the waterproof coal pillar usually suffers from different degrees of dynamic load from the overlying strata, and its internal water distribution is non-uniform. Although the traditional “water content” index can reflect the overall water content, it is difficult to describe the non-uniform characteristics of the soaking space. Therefore, it is of great significance to clarify the dynamic failure mechanism of coal and rock mass under different immersion conditions for stability zoning control. Methods On this basis, the coal–rock combined bodies under three different forms of immersion, namely: complete immersion, unilateral immersion, and non-immersion were prepared. These …
