Precipitation hardening in Mg–Zn–Sn alloys with minor additions of Ca and Si
Authors: Cohen S. , Goren-Muginstein G. , Avraham S. , Rashkova B. , Dehm G. , Bamberger M. 
Published: February 2022

AbstractAl-free Mg–Zn alloys with alternative alloying elements were investigated in order to form Mg–Zn-based alloys with improved thermal stability. Based on thermodynamic calculations, Zn and Sn additives are expected to form stable intermetallic phases with Mg and cause precipitation hardening. An Mg alloy containing 4.5 wt.% Zn and 3.8 wt.% Sn was examined in detail and subsequently alloyed with Ca and Si, in order to promote additional precipitation. The as-cast microstructure and its stability during exposure to elevated temperatures were investigated. Precipitation hardening was investigated in the temperature range of 175 – 250 °C by Vickers hardness measurements and analysis of the microstructure evolution, using X-ray diffraction and electron microscopy techniques. During aging at 175 °C for 1 to 96 h, two hardness maxima were observed: the first after 2 h, and the second after 16 h. The occurrence of two hardness peaks can be related to a precipitation sequence. Firstly, MgZn2precipitates form, and secondly Mg2Sn. The results indicate that the precipitation mechanism is most likely diffusion-controlled. The precipitates are uniformly distributed in the Mg matrix with two morphologies: needle- and plate-like shapes. The addition of Si and Ca did not result in the expected effect on the precipitation behavior.
Locally Grounded Practices, Global Conversations

Abstract
This text reflects on the author’s experience as part of the International Federation for Public History (IFPH) since 2015. In particular, it discusses what IFPH has meant for practitioners trying to leverage public history in service of social change in contexts of historical inequality and violence, and how it could potentially enhance its service even more. The text emphasizes how different local trajectories have resulted in different approaches to public history practice and makes an invitation to continue pushing for the de-centering and de-colonization of the field of public history by putting into question the academic limitations inherited from the epistemologies and trajectories of the Global North.

Rethinking Death’s Sacredness: From Heraclitus’s frag. DK B62 to Robert Gardner’sDead Birds
Authors: Segovia Carlos A. 
Published: February 2022

AbstractThis article examines death’s symbolic rolevis-à-vislife in cross-cultural perspective. It surveys various ways of suppressing, nuancing, or minimising death’s effects and different ways of assuming its non-impasse through a cross-disciplinary lens that combines ethnographic inquiry, philosophical conceptualisation, and a secular, religious studies approach to the sacred. Zoroastrian and pre-Rabbinic Jewish views on the resurrection of the body, Gnostic and Neo-Gnostic takes on the immortality of the soul, and ancient-Greek, Hindu, and medieval Peripatetic claims about the continuity of life beyond death are thus brought into discussion and confronted with the Epicurean dismissal of death’s relevance for us. Additionally, drawing on Heraclitus’s frag. DK B62 and Robert Gardner’s fieldwork among the Dani of Papua New Guinea, I argue that assuming death as life’s sacred and non-negotiable limit need not entail resignation before it, be it untroubled or despaired. For while life outlives us, life itself would be nothing determinate if our finitude were not to contain it, which shows that death is life’s final condition of possibility; and when humans do not lose sight of their mortality, they tend to reaffirm their aliveness so as to stress life’s sacredness before death’s terrible presence, which proves that death is not only life’s limit, but also life’s antagonist. I conclude by making the point that differences as to the exact nature of death’s role in life affect our understanding of what life is: momentary joy, boundless renewal, or tragic gift.

This study aims to determine the school's efforts in building student democratic attitudes through OSIS at SMP Negeri 22 Semarang. The results showed that schools made an effort to provide an understanding of political education. The OSIS management has implemented the understanding of political education provided by the school and can be seen through its activities. The implementation of understanding political education in building democratic attitudes is still not optimal. The active participation of the OSIS management includes; (1) decision making, (2) implementation, (3) taking benefits, (4) evaluation, and (5) social attitudes. Meanwhile, the results of the analysis of the role of political education in building student democratic attitudes show that coaching seeks to build the awareness of the student council officials, motivation plays a role in problem solving, and evaluation plays a role in knowing the shortcomings of the student council administrators.
Penelitian ini bertujuan untuk mengetahui upaya sekolah dalam membangun sikap demokratis siswa melalui OSIS di SMP Negeri 22 Semarang. Hasil penelitian menunjukkan bahwa sekolah berupaya dalam memberikan pemahaman pendidikan politik. Pengurus OSIS sudah mengimplementasikan pemahaman pendidikan politik yang diberikan sekolah serta dapat diketahui melalui aktivitasnya. Implementasi pemahaman pendidikan politik dalam membangun sikap demokratis masih ada yang belum maksimal. Partisipasi aktif pengurus OSIS meliputi; (1) pengambilan keputusan, (2) pelaksanaan, (3) pengambilan manfaat, (4) evaluasi, dan (5) sikap sosial. Sedangkan hasil analisis peran pendidikan politik dalam membangun sikap demokratis siswa menunjukkan bahwa pembinaan berupaya dalam pembentukan kesadaran pengurus OSIS, motivasi berperan dalam penyelesaian masalah, dan evaluasi berperan dalam mengetahui kekurangan pengurus OSIS.
