Radiolitid rudists: an underestimated archive for Cretaceous climate reconstruction? Vrije Universiteit Brussel
Rudist shells are important archives for palaeoenvironmental reconstructions in the greenhouse world of the Cretaceous. Radiolitids, a family of rudists became very abundant dwellers of the shallow marine carbonate platforms during the Cretaceous. Still, due to the complex structure of their low-Mg calcite outer shell layer, radiolitids are often deemed unsuitable for palaeoenvironmental reconstructions. The aim of this study is to present a ...
Schuilen in de schaduw. Een sociologisch onderzoek naar de sociale constructie van verblijfsillegaliteit. KU Leuven
In dit proefschrift onderzochten we de sociale constructie van mensen zonder wettig verblijf of verblijfsillegaliteit in de Vlaams-Belgische samenleving. De originaliteit van deze studie ligt in de gehanteerde sociologische invalshoek vanuit meerdere databronnen. De meeste onderzoeken naar documentlozen vertrekken vanuit een antropologische inslag. Vaak worden daarbij bepaalde etnische groepen of een aantal nationaliteiten gevolgd in een bepaald ...
Tracing timing of growth in cultured molluscs using strontium spiking Vrije Universiteit Brussel
Introduction: Growth experiments present a powerful tool for determining the effect of environmental parameters on growth and carbonate composition in biogenic calcifiers. For successful proxy calibration and biomineralization studies, it is vital to identify volumes of carbonate precipitated by these organisms at precise intervals during the experiment. Here, we investigate the use of strontium labelling in mollusc growth experiments. ...
Cardiovascular Efficacy and Safety of Bococizumab in High-Risk Patients Vrije Universiteit Brussel
BACKGROUND Bococizumab is a humanized monoclonal antibody that inhibits proprotein convertase subtilisin-kexin type 9 (PCSK9) and reduces levels of low-density lipoprotein (LDL) cholesterol. We sought to evaluate the efficacy of bococizumab in patients at high cardiovascular risk. METHODS In two parallel, multinational trials with different entry criteria for LDL cholesterol levels, we randomly assigned the 27,438 patients in the combined trials ...
Immiscible silicate liquids and phosphoran olivine in Netschaëvo IIE silicate: Analogue for planetesimal core–mantle boundaries Vrije Universiteit Brussel KU Leuven
Abstract We have investigated a piece of the Netschaëvo IIE iron meteorite containing a silicate inclusion by means of electron microprobe analysis (EMPA) and transmission electron microscopy (TEM). Netschaëvo contains chondrule-bearing clasts and impact melt rock clasts were also recently found. The examined inclusion belongs to the latter and is characterized by a porphyritic texture dominated by clusters of coarse-grained olivine and ...
Isotopes in Cosmochemistry: Recipe for a Solar System Vrije Universiteit Brussel
Extreme isotopic variations among extraterrestrial materials provide great insights into the origin and evolution of the Solar System. In this tutorial review, we summarize how the measurement of isotope ratios can expand our knowledge of the processes that took place before and during the formation of our Solar System and its subsequent early evolution. The continuous improvement of mass spectrometers with high precision and increased spatial ...
Ice core evidence for a recent increase in snow accumulation in coastal Dronning Maud Land, East Antarctica Vrije Universiteit Brussel
Ice cores provide temporal records of snow accumulation, a crucial component of Antarctic mass balance. Coastal areas are particularly under-represented in such records, despite their relatively high and sensitive accumulation rates. Here we present records from a 120 m ice core drilled on Derwael Ice Rise, coastal Dronning Maud Land (DML), East Antarctica in 2012. We date the ice core bottom back to 1745 ± 2 AD. δ18O and δD stratigraphy is ...
