Asclimate change intensifies, local governments are essential in implementing adaptation measures to specific climate risks. To gain insight into the relationship between the current local adaptation policies and the specific climate risks, the following research question is answered: What is the relationship between the stringency of municipal climate adaptation policies and local climate change risks in the Netherlands? To explore this, a risk analysis using the data analysis regarding local hazards and a social vulnerability index is developed. Additionally, a conceptual design of a policy stringency index is created. The results show that Dutch local governments predominantly focus on heat stress and waterlogging, while the effects of droughts are insufficiently addressed. Efforts to align the local policies with the risks, including increased collaboration and expanding the local knowledge base, are recommended.

[Background] It is expected that thrombus density and perviousness measurements are dependent on CT slice thickness, because density values are blurred in thicker slices. This study quantifies the effect of slice thickness on thrombus density and perviousness measurements. [Methods] Thrombus density and perviousness measurements were performed in 50 patients for varying slice thicknesses, using a manual and semi-automated technique. Linear regression was performed to determine the dependence of density measurements on slice thickness. Paired t-tests were used to test for differences in density and perviousness measures for varying slice thickness. [Results] Thrombus density decreased for increasing slice thickness with approximately 2HU per mm. Perviousness measurements were significantly higher for thick slice compared to thin slice NCCT. [Conclusion] Thick slice NCCT scans result in an underestimation of thrombus density and overestimation of thrombus perviousness.
