The Volcanic Hazards of Jan Mayen Island (North-Atlantic)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-04)
Hazard assessment of remote volcanic islands provides many challenges compared to other volcanoes and volcanic fields. Here we present the first systematic volcanic hazard assessment of Jan Mayen Island, a remote island located in the North-Atlantic Ocean and home to the northernmost active subaerial volcano in the world (Beerenberg Volcano), and we discuss some of the challenges and characteristics ...

Artificial Thawing of Frozen Ground: A Review
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-27)
Understanding the freezing and thawing processes in porous media such as soils is important, especially in regions experiencing seasonal frost or permafrost. These processes have a wide range of implications as diverse as how to maintain the structural integrity of roads, railways, pipelines, and buildings, to when to plant seeds during the growth season. Thawing of frozen ground is the opposite ...
A Review on Emerging Cementitious Materials, Reactivity Evaluation and Treatment Methods
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-05)
Alternative to traditional concrete, sustainable concrete reduces cement content, waste management issues, and CO2 emissions. To achieve sustainable concrete, waste materials can be used as supplementary cementitious materials (SCMs) to partially replace cement. Fly ash, ground-granulated blast furnace slag, and silica fume have been heavily studied as SCMs. However, due to the retirement of coal-fired ...
Evaluating of melting-ice process in a vertical pipe with consideration of net sensible heat
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-19)
In ice-melting process, motion of liquid–solid interface is complicated due to moving boundary, which is also called Stefan interface problem. Although the Stefan model has been widely utilized, it frequently overestimates the melting rate. In the present study, the net-sensible-heat of the phases are taken into account as an additional physical effect to the Stefan model for one-phase case and ...
