Tunnel Surrounding Rock Deformation Characteristics and Control in Deep Coal Mining

Geomaterials, 2013
In order to study the failure characteristics and control method of deep tunnel surrounding rock, based on the stress test, the structure and stress state of the main transportation tunnel surrounding rock in Mine Zhaogezhuang level 14 was analyzed, and it shows that the surrounding rock is exposed to an interphase hard and soft disadvantageous ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Mapping of landslide susceptibility of coastal cliffs : the Mont-Roig del Camp case study [PDF]

, 2012
The weathered and fractured conglomerate cliffs of Mont Roig del Camp constitute a rock fall hazard for the surrounding pocket beaches and, therefore, for the population that frequent them, especially over the summer.

Functional Connectivity Linked to Cognitive Recovery After Minor Stroke

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Patients with minor stroke exhibit slowed processing speed and generalized alterations in functional connectivity involving frontoparietal cortex (FPC). The pattern of connectivity evolves over time. In this study, we examine the relationship of functional connectivity patterns to cognitive performance, to determine ...

Research Progress on Safety Control of Surrounding Rock-Support System in Deep Buried Soft Rock Tunnels

IOP Conference Series: Earth and Environmental Science, 2021
Abstract The deep-buried soft rock tunnel has large deformation degree and long duration, which makes the surrounding rock-support very difficult. How to formulate effective design countermeasures to control soft rock deformation is one of the important technical problems in the design and construction of deep-buried soft rock tunnels ...
