Microstructure and mechanical properties of AZ61 Mg alloy prepared by multi directional forging

Transactions of Nonferrous Metals Society of China, 2010
Abstract AZ61Mg alloy was multi directionally forged (MDFed) during decreasing temperature condition from 643 K to 483 K at a true strain rate of 3×10−3 s−1 up to cumulative strain of ΣΔe=4.0 at maximum. A pass strain of Δe=0.8 was employed. While average grain size decreased gradually with increasing cumulative strain, the evolution of fine-grained ...

‘We Do Not Forget, We Do Not Forgive’: Anti‐Feminicide Collages and the Commemorative Politics of Care in Urban Space

Tijdschrift voor Economische en Sociale Geografie, EarlyView.
Abstract This paper explores the commemorative practices of two feminist collectives engaging in anti‐feminicide collages in the cities of Paris and Montreuil. Based on ethnographic fieldwork conducted between 2023 and 2025, it examines how these activist interventions, as temporary urban memorials, intersect memory‐work and care‐work in urban space ...

Community‐Driven Research Priorities for Genetic Counseling: Shaping the Future of Genetic Counseling Research by Centering Multicultural Perspectives

Journal of Genetic Counseling, Volume 35, Issue 4, August 2026.
ABSTRACT Community‐based participatory research (CBPR), a research approach that centers the collective strengths of community‐researcher partnerships, can direct future genetic counseling (GC) research initiatives toward issues that are critical to communities most impacted by genomic healthcare disparities.

Microstructure Evolution of AZ80 Magnesium Alloy during Multi-Directional Forging Process

MATERIALS TRANSACTIONS, 2014
Grain refinement of a magnesium alloy, AZ80, was studied in multi-directional forging (MDF) with decreasing temperatures from 683 to 573K. The MDF was carried out up to accumulative true strains of around 7 with changing the loading direction from pass to pass.

Comparing TFP Catching-up and Capital Deepening in US and European Growths: A Directional Distance Function Approach [PDF]

In Solow’s model the income convergence between countries arises from two main sources: a capital deepening effect resulting from the diminishing returns of the production technology and a technological transfer/diffusion effect related to Total Factor ...

Evolving Pathways of Departure and Return in Rural Thailand

Population, Space and Place, Volume 32, Issue 5, July 2026.
ABSTRACT This paper draws on a forty‐year longitudinal (1982–2022) village study of Thailand to reflect on how circulation persists, but in new ways. We trace evolving migration flows over a period during which Thailand progressed from low‐income to upper‐middle‐income status, and Non Tae and Tha Song Korn from semi‐subsistence rice‐growing communities
