Stabilisation of CCA-contaminated soil: assessment of amendments for immobilization of chromate cupper arsenate (CCA)

Stabilisation of trace element contaminated soil is a soil remediation method used to reduce the mobile fraction of critical elements in the soil using soil additives (amendments). The stabilisation of trace elements occurs through i.e. sorption, co-precipitation or complex formation. In this

Solar Mid-Term Periodicities

The investigations in this thesis are motivated by the discovery of a quasi- biennial fluctuation of the sunspot umbra-penumbra area ratio (U/P) in the Debrecen Photoheliographic Data (DPD), a detailed catalogue of sunspot activity. A summary of the phenomenon and the analyses

Laser hardning of cutting tools

Nowadays, most of the tools of Volvo Cars Body Components (VCBC) in Olofström are hardened by flame hardening or induction hardening process. Indeed, VCBC has developed their own equipment for flame and induction hardening: However, Volvo has detected that 74% of the
