In the aftermath of the Guatemalan civil war (1960-1996), a large number of witness accounts claim neighbours, relatives, and friends were deeply implicated in the Cold War terror campaign which successive military governments waged against alleged communists or so-called subversive terrorists. Witness testimony and much of the extant literature of the civil war suggests many ordinary Guatemalans helped progress surveillance and death indirectly ...

In 2011 and 2012, the COPHES/DEMOCOPHES twin projects performed the first ever harmonized human biomonitoring survey in 17 European countries. In more than 1800 mother-child pairs, individual lifestyle data were collected and cadmium, cotinine and certain phthalate metabolites were measured in urine. Total mercury was determined in hair samples. While the main goal of the COPHES/DEMOCOPHES twin projects was to develop and test harmonized ...

BACKGROUND: This study aimed to determine the impact of pulmonary complications on death after surgery both before and during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. METHODS: This was a patient-level, comparative analysis of two, international prospective cohort studies: one before the pandemic (January-October 2019) and the second during the SARS-CoV-2 pandemic (local emergence of COVID-19 up to 19 April ...

A homogenous intensity distribution along the cube texture fibre is important to achieve an easy magnetization in non-oriented electrical steels. Several alternatives have been discussed in literature to achieve this goal namely, tertiary recrystallization (surface energy controlled), decarburization annealing, two step cold rolling (strain induced boundary migration), twin-roll thin strip casting (directional solidification), phase ...

© 2015 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved. We introduce a liquid metallurgy synthesized, non-equiatomic Fe40Mn40Co10Cr10 high entropy alloy that is designed to undergo mechanically-induced twinning upon deformation at room temperature. Microstructure characterization, carried out using SEM, TEM and APT shows a homogeneous fcc structured single phase solid solution in the as-cast, hot-rolled and homogenized ...

The AA3003 alloy is widely used as fin material in heat exchangers. The life time of these heat exchangers is mostly determined by their corrosion properties. Twin roll casting (TRC) of AA3003 material is known to often result in the formation of a macrosegregation area of alloying elements towards the centre plane of the casted strip (centre line segregation = CLS). Considering the potential exposure of cross-sectional areas of TRC material in ...

The production of aluminium foil products is typically done by means of Direct
Chill (DC) casting. However, this casting technique requires the need for
expensive hot rolling facilities, to ensure a proper reduction in thickness of the
foil products. Therefore, an alternative technique, which does not require the
need for such expensive hot rolling facilities, became of significant interest for
the aluminium industry. ...
