Suitability of ground-based SfM-MVS for monitoring glacial and periglacial processes [PDF]

open access: yes, 2016
Photo-based surface reconstruction is rapidly emerging as an alternative survey technique to lidar (light detection and ranging) in many fields of geoscience fostered by the recent development of computer vision algorithms such as structure from motion ...

Field investigations of high stress soft surrounding rocks and deformation control

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2015
AbstractField investigations of high stress soft rock deformations show that the high stress soft rock roadway can slide with large deformation. Severe extrusion and floor heave can also be subsequently observed. The supported roadway can be locally damaged or completely fail, where the floor has a large deformation and/or is seriously damaged.

Lose the plot: cost-effective survey of the Peak Range, central Queensland [PDF]

open access: yes, 2013
The Peak Range (22˚ 28’ S; 147˚ 53’ E) is an archipelago of rocky peaks set in grassy basalt rolling-plains, east of Clermont in central Queensland. This report describes the flora and vegetation based on surveys of 26 peaks.

Fault reactivation by fluid injection: Controls from stress state and injection rate [PDF]

open access: yes, 2018
We studied the influence of stress state and fluid injection rate on the reactivation of faults. We conducted experiments on a saw-cut Westerly granite sample under triaxial stress conditions.

Latest progress on study of stability control of roadway surrounding rocks subjected to rock burst

open access: yesProcedia Earth and Planetary Science, 2009
AbstractRock burst has caused tremendous hazards in coal mining. Usually, it can cause roof falling suddenly, sometimes even closing and jamming abruptly; so it has become one of the three most difficult problems of deep mining in the world. The authors discussed the present study in this field at home and abroad and introduced the latest progress ...

Lines of Flight: Everyday Resistance along England’s Backbone [PDF]

open access: yes, 2009
The visual and the cultural impact of ‘social industry’ has made a permanent impression on the landscape and on individual minds, whether for ill or for good, particularly in the Peak and Pennines region of northern England.

Colon cancer cell-derived 12(S)-HETE induces the retraction of cancer-associated fibroblast via MLC2, RHO/ROCK and Ca2+ signalling [PDF]

open access: yes, 2016
Retraction of mesenchymal stromal cells supports the invasion of colorectal cancer cells (CRC) into the adjacent compartment. CRC-secreted 12(S)-HETE enhances the retraction of cancer-associated fibroblasts (CAFs) and therefore, 12(S)-HETE may enforce ...

Research and application of pre-stressed continuous surrounding rock control technology

open access: yesMeikuang Anquan, 2021
Pre-stressed continuous surrounding rock control technology was proposed to solve the problem of serious deformation and destruction of the return air lane of No. 5 working face of Ⅱ2-1 coal in Lingdong Mine. First of all, the mechanical model of the anchor bolt pre-stress transfer in the surrounding rock was established through theoretical analysis ...
