History of Dutch Shell

Jan Luiten Van Zanden, Joost Jonker, Keetie Sluyterman & Stephen Howarth
Understanding oil is essential for understanding modern history. The 20th century has rightly been called the century of oil, and the beginning of the 21st century suggests that this strategic commodity still gains in importance. From its creation in 1907 Royal Dutch Shell has played a key role in the global oil industry. For most of the 20th century Royal Dutch Shell was either the largest or, after Standard Oil/Exxon, the second largest oil company....

Bicarbonate-stimulated membrane reorganization in stallion spermatozoa

Chris H.A. Van De Lest
"Bicarbonate-stimulated membrane reorganization in stallion spermatozoa", published in: Frontiers Cell and Developmental Biology https://www.frontiersin.org/articles/10.3389/fcell.2021.772254 This study aimed to investigate and clarify several aspects of stallion sperm capacitation occurring in the presence of bicarbonate, calcium and albumin. Specifically, re-organization of the plasma membrane after the initiation of sperm capacitation was investigated using lipidomics, cryo-electron microscopy, flow cytometry and complementary biochemical strategies. To this end, phosphatidylserine (PS) and phosphatidylethanolamine exposure in viable sperm was monitored with flow...

Data from seismic slip-pulse experiments simulating induced earthquake rupture in the Groningen gas field

Luuk Bernd Hunfeld
Rock materials show dramatic dynamic weakening in large-displacement (m), high-velocity (~1 m/s) friction experiments, providing a mechanism for the generation of large, natural earthquakes. However, whether such weakening occurs during induced M3-4 earthquakes (dm displacements) is unknown. We performed rotary-shear experiments on simulated fault gouges prepared from the source-, reservoir- and caprock formations present in the seismogenic Groningen gas field (Netherlands). Water-saturated gouges were subjected to a slip pulse reaching a peak circumferential velocity of...

Data supplement to \"Salt marsh and tidal flat area distributions along three estuaries\"

Harke Douma
Data was generated for three estuaries by automated classification of false-colour aerial imagery. The estuaries are the Western Scheldt, the Eastern Scheldt and the Ems-Dollard in the Netherlands. The vector data of land cover classes are for the intertidal zones of the three estuaries. The original aerial imagery is available from Rijkswaterstaat. The automated method can be applied in other estuaries and tidal basins, such as the Wadden Sea, provided that high-quality areal imagery is...

Rater agreement for assessment of equine back mobility at walk and trot compared to quantitative gait analysis.

T.J.P. Spoormakers
Background: Lameness assessment in horses is still predominantly performed using subjective methods. Visual assessment is known to have moderate to good intra-rater agreement but relatively poor inter-rater agreement. Little is known about inter- and intra-rater agreement on the evaluation of back motion, for which no objective measurement technique in a clinical setting is available thus far. Objectives: To describe inter- and intra-rater agreement of visual evaluation of equine back mobility. Study design: Rater reliability study...

M-Tool data analysis script

Wouter Van Boxtel & Karlijn L. Van Den Broek
This R-script provides M-Tool users with a starting point for their data analysis. The script uses the edge list produced by M-Tool and transforms these into centrality measures, including in- and out-degree, in- and out-strength, and mean in- and out-degree weight. Users need to download both scripts, save their data file in the same folder, and enter the name of their data file in the script to obtain the centrality measures. The output consists of...

Data supplement of \"Tectonic context and possible triggering of the 2019-2020 Puerto Rico earthquake sequence\"

Rob M.A. Govers
Paper Abstract: An historically unprecedented seismic moment was released by crustal events of the 2019-2020 earthquake sequence near southwest Puerto Rico. The sequence involved at least two, and per-haps three interacting fault systems. The largest Mw 6.4 event was likely triggered by left lateral strike-slip events along the eastern extension of the North Boquerón Bay-Punta Montalva fault zone. The mainshock occurred in a normal fault zone that extends into a region where previous studies documented...
