The role of women within the fifth column in Madrid during the Spanish Civil War (1936-39) by Flynn, A

“…Anti-Republican women were the first to mobilise resistance in the rearguard and they played a vital role in the construction of a subversive national Catholic imaginary in the capital which was forged in the crucible of war. Of course, this imaginary predates the Civil War.[1] However, circumstances of war and extreme violence lent a new urgency and relevance to ideas of Catholic ‘crusade’ and ‘holy war.’ …”

Determination of Silicon Isotopic Compositions of Rock and Soil Reference Materials by MC-ICP-MS by YANG Lin, SHI Zhen, YU Huimin, HUANG Fang

“…METHODS Alkali fusion method was used for sample digestion.Approximately 3-5mg of sample powder and 200mg of powdery NaOH were weighed in a 10mL silver crucible and heated.The Si purification was obtained using cation exchange resin AG50W-X12.6mol/L HNO3 and ultrapure water were used to clean the resin before sample loading.Silicon isotopes were measured by multi-collector inductively coupled plasma-mass spectrometry (MC-ICP-MS, Neptune Plus) at the laboratory in the University of Science and Technology of China (USTC), and the instrument mass bias was corrected by standard-sample-standard method, with a bracketing standard of NBS-28.The long-term reproducibility (over two years) of Si isotope analysis of one in-house standard (USTC-Si) and one international rock reference material (BHVO-2) were represented, with the δ30Si values of USTC-Si and BHVO-2 of-0.07‰±0.06‰(n=117, 2SD) and-0.29‰±0.06‰(n=320, 2SD), respectively.During Si isotope analysis, two rock reference materials BHVO-2 and AGV-2 were also analyzed to ensure the precision and accuracy of the data.The Si isotopic compositions of BHVO-2 and AGV-2 were consistent with the reported data in the previous literature (Figure 3), demonstrating the reliability of this measurement. …”
