Adsorption Desulfurization of Liquid Fuel Using a Blend of Date Stones and Walnut Shells by Box–Behnken Design

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT A specific microporous KOH/activated‐biochar (K/BC) was produced from a blend of date stones (DS) and walnut shells (WS) and used in the adsorptive desulfurization (ADS) of two types of model fuel DBT/n‐hexane (S‐hex), DBT/cyclohexane (S‐cyclohex).

Exposure to Occupational Inhalants and the Risk of Developing Rheumatoid Arthritis: A Systematic Review and Meta‐Analysis

Arthritis &Rheumatology, EarlyView.
Objective Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by joint pain, swelling, and stiffness. Although smoking is a well‐established risk factor for RA, the role of occupational inhalants in RA development is less well recognized.

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

Effect of Coalbed Methane Well Fracturing on Slope Stability of Open‐Pit Coal Mine: A Case Study of Shengli East No. 2 Open‐Pit Coal Mine [PDF]

Advances in Civil Engineering, 2020
The impact of hydraulic fracture from CBM well fracturing on slope stability of the Shengli East No. 2 open‐pit coal mine is analyzed by numerical simulation and limit equilibrium methods. The interference effect of coalbed methane (CBM) well fracturing on slope stability of the open‐pit coal mine promotes the coordinated development of CBM, and open ...

Strain‐based modeling and analysis for rock blasting and geomechanics applications

Deep Underground Science and Engineering, EarlyView.
This paper introduces a novel strain‐based modeling approach for blasting and geomechanical applications, using measurable variables like particle velocity, strain, and displacement. By bypassing complex constitutive relations, strain‐based models capture critical blasting trends and full‐blast design parameters with minimal calibration.
