Scheurvorming in jong beton: Onderzoek biedt nieuwe inzichten in de spanningsrelaxatie bij jong beton
No full textBeton is tijdens het verharden onderhevig aan thermische en autogene vervormingen. Wanneer deze worden verhinderd, resulteert dit in spanningen en het risico op scheurvorming, mede afhankelijk van relaxatie. Aan de TU Delft is onderzoek gedaan naar het effect van spanningsrelaxatie op scheurvorming in jong beton. In tegenstelling tot de verwachtingen, blijkt dat spanningsrelaxatie in de eerste twee dagen juist resulteert in een verhoogd risico op scheurvorming bij bepaalde constructies met verhinderde vervorming. Ook blijkt dat autogene zwelling daarbij een significante rol speelt, die tot op heden in de norm buiten beschouwing wordt gelaten.Materials and EnvironmentConcrete Structure

Mito-phylogenetic relationship of the new subspecies of gentle monkey Cercopithecus mitis manyaraensis, Butynski & De Jong, 2020
No full textIn 2020, a new subspecies was described in the Cercopithecus mitis complex, the Manyara monkey C. m. manyaraensis, Butynski & De Jong, 2020. The internal taxonomy of this species complex is still debated, and the phylogenetic relationships among the taxa are unclear. Here we provide the first mitochondrial sequence data for C. m. manyaraensis to determine its position within the mitochondrial phylogeny of C. mitis. This subspecies clusters within the youngest (internal divergences between 1.01 and 0.42 Ma) of three main taxonomic clades of C. mitis. Its sister lineages are C. m. boutourlinii (Ethiopia), C. m. albotorquatus (Kenya and Somalia), C. m. albogularis (Kenya and Tanzania), and C. m. monoides (Tanzania and Mozambique). In general, the phylogenetic tree of C. mitis based on mitochondrial sequence data indicates several paraphyletic relationships within the C. mitis complex. As in other African cercopithecines (e.g. Papio and Chlorocebus), these data are suitable for reconstructing historic biogeographical patterns, but they are only of limited value for delimitating taxa

Hydrography and velocity data from the Long-term Ocean Circulation Observations (LOCO) mooring in the central Irminger Sea: Deployment ten (LOCO2_10) August 2012 to July 2014
No full textThe data set under this specific DOI contains data from the tenth LOCO2 deployment (LOCO2_10), from 2 August 2012 to 26 July 2014.
Data from other deployments can be found through the related identifyers.
The LOCO2 mooring was started as part of the Dutch Long-term Ocean Circulation Observations project. LOCO2 was moored in the central Irminger Sea at approximately 59.2N, 39.5W from summer 2003 until summer 2018. It was equipped with Acoustic Doppler Current Profilers for the upper ocean (2500m) circulation, a near bottom SBE37 to record the temperature and salinity of the Denmark Strait Overflow Water and (from the 10th deployment onwards) another SBE37 at around 150m. A McLane Moored Profiler (MMP) equipped with a CTD was programmed to make profiles along the mooring cable between ~150m depth and ~2400m depth.
LOCO2 was positioned in the center of the Irminger Gyre, underneath the strong atmospheric forcing of the Greenland Tip Jet, in order to study deep winter convection in the Irminger Sea. Data and results are described in the following publications:
