The National Science Foundation (NSF), National Institutes of Health (NIH), and other major research funders have recognized the necessity for support of scientific research teams; yet, there is limited evidence about, how scientific teams build the infrastructure for the teams; how to use the ...
research object,the permeability tests under the constant amplitude cycle loading and unloading were conducted by using the self-developed triaxial stress seepage experiment system,and the response characteristics of permeability to the stress level in the fatigue damage process of coal samples were ...
The slip and the corresponding precursors were described by monitoring the displacement, strain, and acoustic emissions (AEs) of coal and rock parting blocks during testing, and the experimental results were verified by analyzing the microseismic (MS) effects during the working face advancing in a ...
The experimental system was equipped with two operating modes: the MQL mode and the flood cooling mode. In light of the formation mechanisms of oil mist, the rotation speed and temperature of the work-piece were selected as processing parameters. For the MQL mode, system parameters such as ...
All students provided informed consent to the use of the anonymized data by READY Education and research partners. All experimental protocols were approved by the Columbia University Ethics Board, and all methods carried out were in accordance with the Board’s guidelines and regulations. The data ...
The creep characteristics and potential deformation patterns of gangue backfill material are crucial in backfill mining operations. This study utilizes crushed gangue from the Gangue Yard in Fuxin City as the research material. An in-house designed, larg
Four stages of alteration and mineralisation are recognised: Stage 1 garnet–biotite alteration; Stage 2 biotite–magnetite alteration; Stage 3 main F–Ba-ore mineralisation; and a Stage 4 pyrite–alloclasite Au–Co–As overprint. The E1 deposit has a more complex history, but Stage 5 has ...
