    Large volcanic eruptions on Earth commonly occur with a collapse of the roof of a crustal magma reservoir, forming a caldera. Only a few such collapses occur per century, and the lack of detailed observations has obscured insight into the mechanical ...
  • McKelvey, Maureen; Saemundsson, Rognvaldur (Informa UK Limited, 2020-06-28)
    The purpose of this article is to better understand the challenges of avoiding the dark side of technological innovation. Specifically, we analyse 10 public investigations started as a reaction to a major crisis in regenerative medicine at the Karolinska ...
  • Shimomura, Yayoi; Hvannberg, Ebba Thora; Hafsteinsson, Hjálmtýr (Springer Nature, 2012-03-17)
    Research has been conducted on how to aid blind peoples’ perceptions and cognition of scientific data and, specifically, on how to strengthen their background in mathematics as a means of accomplishing this goal. In search of alternate modes to vision, ...
  • Atlason, Reynir Smari; Oddsson, Gudmundur V.; Unnthorsson, Runar (Springer Nature, 2017-09-07)
    Heat pumps use the temperature difference between inside and outside areas to modify a refrigerant, either for heating or cooling. Doing so can lower the need for external heating energy for a household to some extent. The eventual impact depends on ...
  • Karlsdóttir, Marta Rós; Heinonen, Jukka; Pálsson, Halldór; Pálsson, Ólafur Pétur (MDPI AG, 2020-06-19)
    The European Union (EU) has made climate change mitigation a high priority though a policy framework called "Clean Energy for all Europeans ". The concept of primary energy for energy resources plays a critical role in how different energy technologies ...
