Validation of transfer functions predicting Cd and Pb free metal ion activity in soil solution as a function of soil characteristics and reactive metal content.

According to recent insight, the toxicity of metals in soils is better related to the free metal ion (FMI) activity in the soil solution than to the total metal concentration in soil. However, the determination of FMI activities in soil solution is a difficult and time-consuming task. An alternative is to use empirical equations (so called transfer functions (TFs)) that relate FMI activity in solution to the reactive metal concentration in the solid phase and to soil properties (pH and organic matter content). Here we test the applicability of two sets of TF for Cd and Pb using independent data from a wide range of soil types and regions that are not represented in the datasets used to derive the TFs. From these soils, soil solution was extracted using four different methods. For all these extracts, FMI activities were calculated from total concentrations in solution using the speciation program WHAM VI. In some of the soils, Cd and Pb FMI activities were also measured using a Donnan membrane technique. Most of these FMI activities deviated from the TF predictions by less than one order of magnitude and were within the 95% confidence interval of the TFs, irrespective of the method used to extract soil solution. Predictability was higher for Pb than for Cd and differed also between the two TF sets

CHECK’D?! : determinants of participation in a two-stage cardiometabolic screening among underserved groups

It has been well established that underserved groups have an increased risk of cardiometabolic disease and are less likely to attend health checks. This differential uptake of health checks leads to suboptimal health gains from cardiometabolic screening and contributes to the widening of health inequalities in society. The cost-effectiveness of the Dutch cardiometabolic health check is still under study, but with the knowledge we already have it seems advisable to focus primarily on the underserved groups, as they have the most to gain from systematic screening. The findings described in this thesis provide strategies to optimize uptake and may be used to design future studies on this topic. In the general discussion we also advocate that the Government should invest in population-based prevention and move away from the trend of taking own responsibility as this may provide underserved groups the best possible opportunities for a healthy life(style).  Hartstichting; Diabetesfonds en Nierstichting.LUMC / Geneeskund

ZZ-boson polarization as a model-discrimination analyzer

Determining the spin of any new particle is critical in identifying the true theory among various extensions of the Standard Model (SM). The degree of $Z$-boson polarization in any two-body decay process $A\to B Z$ is sensitive to the spin assignments of two new particles $A$ and $B$. Considering all possible spin-0, 1/2 and 1 combinations in a renormalizable field theory, we demonstrate that $Z$-boson polarization can indeed play a role of a decisive and universal analyzer in distinguishing the different spin assignments.Comment: 10 pages, 3 figures, 1 tabl
