From National to International Focus – Results and Impacts from the Norwegian National Rd&D Programme for CCS (Climit)
The Norwegian national program for RD&D within CCS (CLIMIT) changed focus towards more international collaboration in 2017. The program has since then allocated approximately 20 percent of the available budget for international joint calls, primarily through the calls set up by the ACT transnational partnership. ACT is the abbreviation for Accelerating CCS technologies, and funding agencies from 16 countries, provinces and regions are collaborating on joint calls and knowledge sharing within this partnership. The effect of allocating a fifth of the available CLIMIT funds to international calls, has led to a shift from basic to applied research and consequently to larger projects of higher industrial interest. The international projects have managed to raise awareness of CCUS as a tool to combat global warming in a much more pronounced way than is normally seen in national RD&D projects.publishedVersio
A mechanistic model for CO2 corrosion with protective iron carbonate films
The mechanistic model of uniform CO corrosion is presented which covers: electrochemical reactions at the steel surface, diffusion of species between the metal surface and the bulk including diffusion through porous surface films, migration due to establishment of potential gradients and homogenous chemical reactions including precipitation of surface films. The model can predict the corrosion rate, as well as the concentration and flux profiles for all species involved. Comparisons with laboratory experiments have revealed the strengths of the model such as its ability to assist in understanding of the complex processes taking place during corrosion in the presence of surface films

Polymorphisms of DNA repair genes and risk of non-small cell lung cancer
Lung cancer is a leading cause of cancer mortality with an inter-individual difference in susceptibility to the disease. The inheritance of low-efficiency genotypes involved in DNA repair and replication may contribute to the differ-ence in susceptibility. We investigated 44 single nucleotide polymorphisms (SNPs) in 20 DNA repair genes including nucleotide excision repair (NER) genes XPA, ERCC1, ERCC2/XPD, ERCC4/XPF and ERCC5/XPG; base excision repair (BER) genes APE1/APEX, OGG1, MPG, XRCC1, PCNA, POLB, POLi, LIG3 and EXO1; double-strand break repair (DSB-R) genes XRCC2, XRCC3, XRCC9, NBS1 and ATR; and direct damage reversal (DR) gene MGMT/AGT. The study included 343 non-small cell lung cancer (NSCLC) cases and 413 controls from Norwegian general population. Our results indicate that SNPs in th
Thermal strain in the mushy zone related to hot tearing
A volume-averaged two-phase model addressing the main transport phenomena associated with hot tearing in an isotropic mushy zone during solidification of metallic alloys has recently been presented elsewhere along with a new hot tearing criterion addressing both inadequate melt feeding and excessive deformation at relatively high solid fractions. The viscoplastic deformation in the mushy zone is addressed by a model in which the coherent mush is considered as a porous medium saturated with liquid. The thermal straining of the mush is accounted for by a recently developed model taking into account that there is no thermal strain in the mushy zone at low solid fractions because the dendrites then are free to move in the liquid, and that the thermal strain in the mushy zone tends toward the thermal strain in the fully solidified material when the solid fraction tends toward one. In the present work, the authors determined how variations in the parameters of the constitutive equation for thermal strain influence the hot tearing susceptibility calculated by the criterion. It turns out that varying the parameters in this equation has a significant effect on both liquid pressure drop and viscoplastic strain, which are key parameters in the hot tearing criterion. However, changing the parameters in this constitutive equation will result in changes in the viscoplastic strain and the liquid pressure drop that have opposite effects on the hot tearing susceptibility. The net effect on the hot tearing susceptibility is thus small
