• A method for measuring wetting and swelling of bentonite using X-ray imaging 

  Harjupatana, Tero; Miettinen, Arttu; Kataja, Markku (Elsevier, 2022)

  A non-invasive method based on X-ray imaging for measuring deformation and water transport in wetting and swelling bentonite samples is introduced. Sequential X-ray images taken of the samples were used to calculate the ...

• Kastuvan bentoniitin muodonmuutosten ja vesipitoisuuden aikakehityksen mittaaminen röntgenkuvauksen avulla 

  Tanttu, Joni (2020)

  Tämän tutkielman tavoitteena oli jatkokehittää kokeellista menetelmää, jossa kastumisen seurauksena tyhjään tilaan laajenevan bentoniitti nimisen savimateriaalin homogenisaatiota seurataan röntgenkuvauksen avulla. Menetelmällä ...

• The topology of spatial networks affects stability in experimental metacommunities 

  Arancibia, Paulina A. (Royal Society Publishing, 2024)

  Understanding the drivers of community stability has been a central goal in ecology. Traditionally, emphasis has been placed on studying the effects of biotic interactions on community variability, and less is understood ...

• Single-particle and collective excitations in the transitional nucleus 166Os 

  Stolze, Sanna; Grahn, Tuomas; Julin, R; Joss, D T; Andgren, K; Auranen, Kalle; Bönig, S; Cox, Daniel; Darby, I G; Doncel, M; Eeckhaudt, S; Greenlees, Paul T; Hadinia, B; Herzáň, Andrej; Jakobsson, Ulrika; Jones, P; Juutinen, Sakari; Ketelhut, S; Konki, Joonas; Kröll, T; Leppänen, A-P; Nyman, M; Page, R D; Pakarinen, J; Partanen, J; McPeake, C G; O’Donnell, D; Peura, Pauli; Rahkila, Panu; Ruotsalainen, Panu; Sandzelius, Mikael; Sarén, Jan; Saygı, B; Scholey, Catherine; Simpson, J; Sorri, Juha; Taylor, M J; Thornthwaite, A; Uusitalo, Juha (IOP Publishing, 2021)

  The mean lifetimes of the lowest energy 2+, 8+ and 9− states in 166Os have been measured using the recoil distance Doppler-shift method in conjunction with a selective recoil-decay tagging technique. These measurements ...

• X-ray tomographic method for measuring 3D deformation and liquid content in swelling materials 

  Harjupatana, Tero; Alaraudanjoki, Jarno; Kataja, Markku (Rakenteiden mekaniikan seura, 2015)

  A non-invasive method for measuring the three-dimensional displacement field and liquid content distribution in a wetting and swelling material using X-ray tomographic imaging is introduced. The method is demonstrated ...
