European Unconventional Oil and Gas Assessment (EUOGA) - Development and application of a unified methodology

Over the last decade, various international and national assessments of shale gas and shale oil resources for most EU-countries have been published. Due to methodological differences and in fundamental assumptions related to the quality and quantity of underlying geological information, these results are not comparable and in some cases not reproducible. This presentation focusses on the development and definition of a uniform methodology for estimating (in-place) shale gas and shale oil resources at the pan-European level within the context of the EUOGA study (EU Unconventional Oil and Gas Assessment). The presented methodology is established to determine estimates of GIIP (Gas Initially In Place) and OIIP (Oil Initially In Place) including associated uncertainty bandwidths originating from the various geological input parameters. The method is applied to 81 onshore shale gas or oil formations from 33 thermogenic and two biogenic basins located within the participating European countries. The results of the assessment include a geological description of the basins together with a general chance of success, a ranking of the individual assessment units and the final calculation of GIIP or OIIP for the formations.JRC.C.3-Energy Security, Distribution and Market

Diversiteit en inclusie bij het Van Gogh Museum

Diversiteit en inclusie: het begint steeds meer een mantra te worden. Organisaties komen superlatieven tekort om te benadrukken hoe divers en inclusief ze zijn. De bittere realiteit is echter dat Nederland onderaan verschillende diversiteitsindexen bungelt. “Beschamend en diep teleurstellend,” was de reactie van minister Ingrid van Engelshoven, toen ze in 2018 met de uitkomst van zo’n index werd geconfronteerd (Volkskrant, 2018). Dat er veel bij komt kijken als je diverser en inclusiever wilt worden, ondervonden wij tijdens een casestudie bij het Van Gogh Museum. Het vergroten van diversiteit en inclusie is wel degelijk mogelijk, maar geen sinecure

Temperature buffering by groundwater in ecologically valuable lowland streams under current and future climate conditions

Groundwater seepage influences the temperature of streams and rivers by providing a relatively cool input in summer and warm input in winter. Because of this, groundwater seepage can be a determining factor in the provision of suitable water temperatures for aquatic biota. Climate warming affects stream and groundwater temperatures, and changes the thermal characteristics of streams leading to the potential disappearance of habitats. In this study the importance of groundwater for the temperature of two Dutch lowland streams and its possible role in mitigating the effects of climate change was determined by combining field measurements and a modelling experiment. Stream temperature measurements using fibre optic cables (FO-DTS) and sampling of 222Rn were done to map localized groundwater inflow. Several springs and seepage ‘hot-spots’ were located which buffered the water temperature in summer and winter. A stream temperature model was constructed and calibrated using the FO-DTS-measurements to quantify the energy fluxes acting on stream water. This way, the contribution to the stream thermal budget of direct solar radiation, air temperature and seepage were separated. The model was then used to simulate the effects of changes in shading, groundwater seepage and climate. Shading was shown to be an important control on summer temperature maxima. Groundwater seepage seemed to buffer the effect of climate warming, potentially making groundwater dominated streams more climate robust. Protecting groundwater resources in a changing climate is important for the survival of aquatic species in groundwater-fed systems, as groundwater seepage both sustains flow and buffers temperature extremes.

Conceptual design and performance study for the first implementation of AGATA at the in-flight RIB facility of GSI

Abstract The main objective of the Advanced GAmma Tracking Array (AGATA) is the investigation of the structure of exotic nuclei at the new generation of RIB facilities. As part of the preparatory phase for FAIR-NUSTAR, AGATA is going to be installed at the FRS fragmentation facility of the GSI centre for an experimental campaign to be performed in 2012 and 2013. Owing to its γ - ray tracking capabilities and the envisaged enhancement in resolving power, a series of in-flight γ - ray spectroscopy experiments are being planned. The present work describes the conceptual design of this first implementation of AGATA at GSI-FRS, and provides information about the expected performance figures. According to the characteristics of each particular experiment, it is foreseen that the target–array distance is adjusted in order to achieve the optimum compromise between detection efficiency and energy resolution, or to cover an specific angular range of the emitted electromagnetic radiation. Thus, a comprehensive Monte Carlo study of the detection sensitivity in terms of photopeak efficiency, resolution and peak-to-total ratio, as a function of the target–array distance is presented. Several configurations have been investigated, and MC-calculations indicate that a remarkable enhancement in resolving power can be achieved when double-cluster AGATA detectors are developed and implemented. Several experimental effects are also investigated. This concerns the impact of passive materials between the target and the array, the angular distribution of the detection efficiency and the influence of target thickness effects and transition lifetimes in the attainable detection sensitivity. A short overview on half-life measurements via lineshape effects utilizing AGATA is also presented

How teacher education institutions cope with challenges of teaching and learning in the digital age.

The assumption underlying the symposium is that teacher education institutions have a dual challenge. On the one hand they need to prepare pre-service students for teaching and facilitating learning in the digital age, including the use of technology in teaching and learning. On the other hand teacher education institutions need to change in order to cope with the challenges of the knowledge society. How Dutch teacher education institutions cope with these challenges is presented and discussed in the symposium

IN-BEAM gamma-RAY ANGULAR DISTRIBUTION AND LIFETIME MEASUREMENTS - EXPERIENCE FROM RISING AND PERSPECTIVES AT FAIR

RISING experiments delivered important knowledge on difficulties in performing prompt in-beam gamma-ray spectroscopy measurements, caused by the use of very fast radioactive beams. The obtained results pointed out possible ways to suppress the overwhelming gamma-ray background that should be considered in setting up new facilities planned at GSI and FAIR. In the course of the RISING campaign, the spectroscopy methods: gamma-ray angular distribution and lifetime measurements useful in deducing B(E2) transition rates were developed. They can be effectively applied in experiments with the new generation gamma-ray detector array AGATA
