Using the broadband records from a regional permanent network, we determined focal mechanisms of 174 small and moderate earthquakes (3.4≤ M w≤6.0) January 2008 to March 2011 in Yunnan, China, by fitting three‐component waveforms P S waves. Results show that predominantly have strike‐slip mechanisms, with occasional normal very few thrust‐faulting events. Most occur upper crust above 16 km depth. We then derive distribution stress field through damped linear inversion using obtained this...
Quantitative investigation on the preferential flow induced by desiccation cracks (PF-DC) remains a great challenge due to soil shrinking-swelling behavior. This work presents series of comparative numerical studies investigate accuracy and substitutability different models in simulating water flux, hydrological response crack evolution PF-DC. As study, an effective dynamic dual-permeability model (DDPM) we recently developed validated was regarded as benchmark model. Three experiments were...
Summary Myoblasts are the primary effector cells that play crucial roles in myogenesis and muscle regeneration following injury. However, isolating purified myoblasts from murine skeletal poses challenges for junior researchers. Here, we present a simplified, low-risk, optimized protocol extraction enrichment of these myogenic progenitor cells. Additionally, demonstrate that, compared to F10 (Ham’s F-10)-based medium, DMEM (Dulbecco’s Modified Eagle’s Medium)-based differentiation medium...
Abstract Climate‐induced desiccation cracks exhibit a hysteresis behavior, referred to as crack dynamic (CDH), where they display different geometric characteristics during the drying and wetting phases at constant soil water content. This phenomenon has complex effect on slope stability, an aspect often overlooked in analytical numerical methods. In this study, we conducted experimental analyses provide new insights into effects of CDH stability. A series laboratory experiments cracking...
Abstract. Preferential flow induced by desiccation cracks (PF-DC) has been proven to be an important hydrological effect that could cause various geotechnical engineering and ecological environment problems. Investigation on the PF-DC remains a great challenge due soil shrinking–swelling behavior. This work presents experimental numerical study of considering dynamic changes cracks. A column test was conducted under wetting–drying cycles investigate their response. The ratios between crack...
The pore structure plays an important role to understand methane adsorption, storage and flow behavior of geological materials. In this paper, the multi-tests including N2 mercury intrusion porosimetry (MIP) CT reconstruction have been proposed on Tashan lamprophyre samples. main findings are listed: (1) size distribution has a broad range ranging from 2-100000nm, among which adsorption pores (<100nm) occupies mainly specific surface areas volume while seepage (>100nm) only...
Prediction of surface subsidence caused by longwall mining operation in inclined coal seams is often very challenging. The existing empirical prediction methods are inflexible for varying geological and conditions. An improved influence function method has been developed to take the advantage its fundamentally sound nature flexibility. In developing this method, original Knothe transformed produce a continuous asymmetrical function. equations final parameters derived from collected data have...
Retained gob-side entry (RGE) is a significant improvement for fully-mechanized longwall mining. The environment of surrounding rock directly affects its stability. Roadside backfilling body (RBB), man-made structure in RGE plays the most important role successful application technology. In field, however, vertical deformation RBB large during panel extraction, which leads to malfunction RGE. order solve problem, roof pre-split employed. According geological conditions as well physical...
On December 18, 2023, an earthquake of 6.2 magnitude occurred in Jishishan County, Linxia Prefecture, Gansu Province. After the earthquake, mudslides Caotan Village and Jintian Village, Zhongchuan Township, Minhe Haidong, Qinghai Province, resulting 20 deaths. we carried ground penetrating radar drone equipment, combined with satellite remote sensing data, disaster site sampling, laboratory sediment particle size shape analysis, to conduct in-depth investigation research on characteristics,...
