Reactive Transport in Porous Media
(Master thesis, 2011-08-01)In this thesis, we show how the common equations for flow in porous media can be expanded to account for geochemical reactions. Furthermore, the complications arising when solving the new equations numerically are described ... -
Reactive transport modelling of hydrate phase transition dynamics in porous media
(Doctoral thesis, 2015-03-27)Gas hydrate is believed to be so abundant in nature that some estimates suggest it contains more than two times equivalent energy of the whole fossil fuels on Earth. Besides, reservoir hydrates have other important aspects ... -
Reactive Transport of CO2 in Saline Aquifers with implicit geomechanical analysis
(Peer reviewed; Journal article, 2009)Geological storage of CO2 in saline aquifers is a promising way to reduce the concentration of the greenhouse gas in the atmosphere. Injection of CO2 will, however, lead to dissolution of minerals in regions of lowered pH ... -
Readout Electronics for the Upgraded ITS Detector in the ALICE Experiment
(Doctoral thesis, 2022-06-03)ALICE is undergoing upgrades during the Long Shutdown (LS) 2 of the LHC to improve its performance and capabilities, and to prepare the experiment for the increases in luminosity provided by the LHC in Run 3 and Run 4. One ... -
“Real-time” genetic monitoring of a commercial fishery on the doorstep of an MPA reveals unique insights into the interaction between coastal and migratory forms of the Atlantic cod
(Peer reviewed; Journal article, 2017-05)With the decline of many of the world’s fisheries, increased regulation, including marine protected areas (MPA), forms an increasingly important role in promoting sustainable resource use. Here, we present a novel “real-time” ... -
Realistic mask generation for matter-wave lithography via machine learning
(Journal article; Peer reviewed, 2023)Fast production of large-area patterns is crucial for the established semiconductor industry and enables industrial-scale production of next-generation quantum devices. Metastable atom lithography with binary holography ... -
A reappraisal of the H–κ stacking technique: implications for global crustal structure
(Journal article; Peer reviewed, 2019)H–κ stacking is used routinely to infer crustal thickness and bulk-crustal VP/VS ratio from teleseismic receiver functions. The method assumes that the largest amplitude P-to-S conversions beneath the seismograph station ... -
Rearing conditions and automated feed distribution systems for zebrafish (Danio rerio)
(Journal article; Peer reviewed, 2022)Zebrafish (Danio rerio) is a well-established animal model, used in a number of research areas. In the last decade, it has also emerged as a tool to evaluate the effects of diets and dietary components and to test novel ... -
Recalibration of the MEPED Proton Detectors Onboard NOAA POES Satellites
(Master thesis, 2013-07-04)In this thesis we have calibrated energetic proton data from the solid state detectors of the MEPED instrument onboard the satellites NOAA 15, 16, 17, 18, and MetOp 02. All these satellites are part of the NOAA/POES program, ... -
Recent and future changes of the Arctic sea-ice cover
(Peer reviewed; Journal article, 2008)The present and future state of the Arctic sea ice cover is explored using new observations and a coupled one dimensional air–sea–ice model. Updated satellite observations of Fram Strait ice-area export show an increase ... -
Recent applications and potential of near-term (interannual to decadal) climate predictions
(Journal article; Peer reviewed, 2023)Following efforts from leading centres for climate forecasting, sustained routine operational near-term climate predictions (NTCP) are now produced that bridge the gap between seasonal forecasts and climate change projections ... -
Recent drought and precipitation tendencies in Ethiopia
(Peer reviewed; Journal article, 2013-05)In 2011, drought in the Horn of Africa again made news headlines. This study aims to quantify the meteorological component of this and other drought episodes in Ethiopia since 1971. A monthly precipitation data set for 14 ... -
Recent ecosystem dynamics in nine North African lakes in the CASSARINA Project
(Peer reviewed; Journal article, 2001)An integrated multi-disciplinary study of nine North African lakes (CASSARINA) aims to establish ecological baselines and to explore responses to 20th century human impacts on their ecosystems. Water chemistry measurements ... -
Recent environmental change and atmospheric contamination on Svalbard as recorded in lake sediments – an introduction
(Peer reviewed; Journal article, 2004)This paper outlines an interdisciplinary project on recent environmental change and atmospheric contamination on the high Arctic archipelago of Svalbard (76º30'N – 80º30'N). It describes the rationale and aims of the project ... -
Recent environmental change and atmospheric contamination on Svalbard as recorded in lake sediments – modern limnology, vegetation, and pollen deposition
(Peer reviewed; Journal article, 2004)Twenty-four lakes on Svalbard were sampled for palaeolimnological studies and are described in terms of their geographical location, catchment characteristics, water chemistry, and flora. No sediment could be retrieved ... -
Recent environmental change and atmospheric contamination on Svalbard as recorded in lake sediments – synthesis and general conclusions
(Peer reviewed; Journal article, 2004)The major patterns of biostratigraphical and geochemical change detected in a multidisciplinary study on recent environmental change and atmospheric contamination on Svalbard are summarised and synthesized. The patterns ... -
Recent environmental change and human impact on Svalbard: the lake-sediment geochemical record
(Peer reviewed; Journal article, 2004)As part of a broader investigation into recent environmental change on Svalbard, the inorganic geochemical record of six lake-sediment cores was analysed. The major temporal trends in sediment elemental composition are ... -
Recent Evolution of Glaciers in the Manaslu Region of Nepal From Satellite Imagery and UAV Data (1970–2019)
(Journal article; Peer reviewed, 2022)Glacierized mountain ranges such as the Himalaya comprise a variety of glacier types, including clean and debris-covered glaciers. Monitoring their behaviour over time requires an assessment of changes in area and elevation ... -
