    Fractal Characteristics of the Spatial Distribution of Mine Earthquake Sources in the Vicinity of a Fault: A Case Study in the Ashele Copper Mine by Congcong Zhao, Shigen Fu, Yinghua Huang

    Published 2024-12-01
    “…This study aims to introduce fractal theory to characterize the spatiotemporal activity fractal characteristics of induced faults intersecting the mining site and roadway during the mining process of the Ashele copper mine in China. Using microseismic systems and fractal theory, a spatiotemporal fractal model of the fault slip process is constructed, and a fractal analysis method is proposed. …”

    Different Genotypes of the Rare and Threatened Moss <i>Physcomitrium eurystomum</i> (Funariaceae) Exhibit Different Resilience to Zinc and Copper Stress by Djordje P. Božović, Marija V. Ćosić, Vladislav Kolarčik, Michal Goga, Claudio Varotto, Mingai Li, Aneta D. Sabovljević, Marko S. Sabovljević

    Published 2025-01-01
    “…The riparian habitat type of this species is often under the influence of contaminated water, and, therefore, we tested the influence of selected potentially toxic elements (PTEs), namely zinc and copper, on the development, physiological features, and survival of the species on two different accessions (German and Croatian). …”

    Improvement in the Mechanical Properties of High Temperature Shape Memory Alloy (Ti50Ni25Pd25) by Copper Addition by Saif ur Rehman, Mushtaq Khan, A. Nusair Khan, Syed Husain Imran Jaffery, Liaqat Ali, Aamir Mubashar

    Published 2015-01-01
    “…The increase in both stresses was attributed to the solid solution strengthening by substitution of Ni atoms with relatively greater atomic radius of copper (Cu) atoms. The overall results suggest that the addition of 5 at% Cu in place of Ni in Ti50Ni25Pd25 alloy is very beneficial to improving the mechanical and shape memory properties and increasing the transformation temperatures.…”
