Shallow landslide susceptibility assessment under future climate and land cover changes: a case study from southwest China
(2023-07)
Artículo
Acceso abiertoThere is no doubt that land cover and climate changes have consequences on landslide activity, but it is still an open issue to assess and quantify their impacts. Wanzhou County in southwest China was selected as the test ... -
Validation and verification of a quasi two-dimensional turbulence model and an eddy detection method for liquid metal magnetohydrodynamics flows
(2023-03-02)
Artículo
Acceso restringido por política de la editorialThe flow of liquid metals in straight rectangular channels with an externally applied transverse magnetic field is considered for breeding blankets in tokamak fusion reactors. Under the tokamak magnetic field, the liquid ... -
Thiol-Ene Networks with Tunable Dynamicity for Covalent Adaptation
(American Chemical Society (ACS), 2022-01-01)
