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....

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...

Grief, depression, and anxiety following job loss: Patterns and correlates

J.H.W. Van Eersel
Abstract Background. Research on grief, depression, and anxiety reactions following job loss is sparse. More insight in this matter could be important for the development of preventive and curative methods addressing the perceived emotional distress following job loss, especially in the case of job loss-related grief reactions. Objective. The aim of this study was to examine job loss-related grief reactions in relation to depression and anxiety symptoms. Method. A sample of 525 Dutch workers (59.8%...

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...

Contact model and numerical modelling results: “Compaction of the Groningen Gas Reservoir Sandstone: Discrete Element Modelling Using Microphysically Based Grain-Scale Interaction Laws”

Mohammad Hadi Mehranpour
Reservoir compaction, surface subsidence and induced seismicity are often associated with prolonged hydrocarbon production. Recent experiments conducted on the Groningen gas field’s Slochteren sandstone reservoir rock, at in-situ conditions, have shown that compaction involves both poro-elastic strain and time-independent, permanent strain caused by consolidation and shear of clay films coating the sandstone grains, with grain failure occurring at higher stresses. To model compaction of the reservoir in space and time, numerical approaches, such as the...

Rotary Shear Experiments on Glass Bead Aggregates

Evangelos Korkolis
Constant sliding velocity (i.e. rate of rotation) friction experiments on mm-thick layers of glass beads, under room temperature and humidity conditions. Stick-slip in sheared granular aggregates is considered to be an analog for the intermittent deformation of the earth’s lithosphere via earthquakes. Stick-slip can be regular, i.e. periodic and of consistent amplitude, or irregular, i.e. aperiodic and of varying amplitude. In the context of seismology, the former behavior resembles the Characteristic Earthquake Model, whereas the...

Continuous versus discrete data analysis for gait evaluation of horses with induced bilateral hindlimb lameness

Ineke Smit
Background: Gait kinematics measured during equine gait analysis are typically evaluated by analysing (asymmetry-based) discrete variables (e.g. peak values) obtained from continuous kinematic signals (e.g. timeseries of datapoints). However, when used for the assessment of complex cases of lameness, such as bilateral lameness, discrete variable analysis might overlook relevant functional adaptations. Objectives: The overall aim of this paper is to compare continuous and discrete data analysis techniques to evaluate kinematic gait adaptations to lameness. Study...

Cooperation between newcomers and incumbents: The role of normative disagreements

Kasper Otten
Cooperation in groups often requires individual members to make costly contributions that benefit the group as a whole. Prior research suggests that shared norms can help to support ingroup cooperation by prescribing common standards of how much to contribute. These common standards may be disrupted when groups undergo membership change, i.e., when members from outgroups enter the ingroup. When newcomers and incumbents have different notions about how much to contribute, a normative disagreement ensues that...
