Experimental study on dynamic behavior analysis of coal and its acoustic emission response characteristics under impact failure

Deep Underground Science and Engineering, EarlyView.
Based on acoustic emission response characteristics, it can be more accurate to identify the damage evolution process of coal under the combined dynamic and static loads, reveal the moment corresponding to coal damage, and identify the characteristics of coal failure. The research results are conducive to the further use of acoustic emission monitoring

Longevity of colloidal activated carbon for in situ PFAS remediation at AFFF‐contaminated airport sites

Remediation Journal, Volume 33, Issue 1, Page 3-23, Winter 2022., 2022
Abstract A review of state per‐ and polyfluoroalkyl substances (PFAS) guidelines indicates that four long‐chain PFAS (perfluorooctanesulfonic acid [PFOS] and perfluorooctanoic acid [PFOA] followed by perfluorohexanesulfonic acid [PFHxS] and perfluorononanoic acid [PFNA]) are the most frequently regulated PFAS compounds.

Microscopic time‐dependent mechanical behavior of shale derived from nanoindentation

Deep Underground Science and Engineering, EarlyView.
This study conducted grid nanoindentation creep tests to systematically analyze the microscopic creep behaviors of shale. Based on the analysis of creep strain rate sensitivity, the primary mechanism of microscopic creep in shale was found to be the extension and closure of microcracks.

A spreadsheet for determining critical soil test values using the modified arcsine‐log calibration curve

Soil Science Society of America Journal, Volume 87, Issue 1, Page 182-189, January/February 2023., 2023
Abstract Soil test correlation data are often used to identify a critical soil test value (CSTV), above which crop response to added fertilizer is not expected. Oftentimes, models are used to determine the CSTV from soil test correlation data, yet most commonly used models have inherent assumptions that may not be valid for these data.

The effect of thermal–hydro–mechanical coupling on grouting in a single fracture under coal mine flowing water conditions

Deep Underground Science and Engineering, EarlyView.
Higher temperature leads to a better relative sealing efficiency with a slow flow rate. Temperature change shows a negative correlation with the seepage pressure and the grouting pressure. The “equivalent grouting point offset” effect of grouting shows an eccentric elliptical propagation.

Thymoquinone induces apoptosis in temozolomide‐resistant glioblastoma cells via the p38 mitogen‐activated protein kinase signaling pathway

Environmental Toxicology, Volume 38, Issue 1, Page 90-100, January 2023., 2023
Abstract Temozolomide (TMZ) can cross the blood‐brain barrier (BBB) and deliver methyl groups to the purine (guanine) bases of DNA, leading to mispairing during DNA replication and subsequent cell death. However, increased expression of the repair enzyme methyl guanine methyltransferase (MGMT), which removes methyl groups from purine bases, counteracts
