The role of plasma-atom and molecule interactions on power & particle balance during detachment on the MAST Upgrade Super-X divertor
Christian Gabriel Theiler, Kevin Henricus Annemarie Verhaegh
This paper shows first quantitative analysis of the detachment processes in the MAST Upgrade Super-X divertor (SXD). We identify an unprecedented impact of plasma-molecular interactions involving molecular ions (likely D2+ ), resulting in strong ion sinks ...
Bristol2023Using PhenoCams to track crop phenology and explain the effects of different cropping systems on yield
CONTEXT: Crop phenology integrates information of how environmental drivers and management practices affect plant performance and crop yield. However, little is known about the impact of cropping systems (CS) on crop phenology and how this relates to diffe ...
ELSEVIER SCI LTD2022Multiscale simulation of erosive wear in a prototype-scale Pelton runner
François Avellan, Ebrahim Jahanbakhsh, Sebastián Camilo Leguizamón Sarmiento, Siamak Alimirzazadeh
The technical capacity to predict the erosion process is instrumental for the optimization of the runner designs and operation strategies of hydroelectric plants. A multiscale model of erosion recently formulated by the authors and validated on a laborator ...
2020Species identity, rather than species mixtures, drives cover crop effects on nutrient partitioning in unfertilized agricultural soil
Alexandre Buttler, Pierre Rémi Mariotte, Mathieu Raymond Santonja, Lucas Georges Jean-Paul Freund
Aims Previous cover crop studies mainly focused on the links between plant uptake and soil fertility, and there is a clear knowledge gap regarding the role of microbes in these processes. Our aim was then to better understand the effects of plant mixtures ...
SPRINGER2020Long-term effects of crop succession, soil tillage and climate on wheat yield and soil properties
Climate change is increasing crop losses and yield variability with impacts for global food security. In this context, conservation agriculture appears as a potential solution to maintain crop productivity, soil fertility and environmental sustainability. ...
ELSEVIER SCIENCE BV2019The effect of accelerated soil erosion on hillslope morphology
Intensive agricultural land use can have detrimental effects on landscape properties, greatly accelerating soil erosion, with consequent fertility loss and reduced agricultural potential. To quantify the effects of such erosional processes on hillslope mor ...
2019Multiscale Simulation of the Hydroabrasive Erosion of a Pelton Bucket: Bridging Scales to Improve the Accuracy
François Avellan, Ebrahim Jahanbakhsh, Audrey Paulette Solange Maertens, Sebastián Camilo Leguizamón Sarmiento, Siamak Alimirzazadeh
Erosive wear of hydraulic machines is a common issue, which results in efficiency degradation, the enhancement of cavitation, and the need for expensive maintenance. Although numerical simulations of the erosion process could be very useful, both for under ...
2019On the theory of drainage area for regular and non-regular points
The drainage area is an important, non-local property of a landscape, which controls surface and subsurface hydrological fluxes. Its role in numerous ecohydrological and geomorphological applications has given rise to several numerical methods for its comp ...
2018Seasonality alters drivers of soil enzyme activity in subalpine grassland soil undergoing climate change
Alexandre Buttler, Konstantin Svetlozarov Gavazov, Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek, Thomas Spiegelberger, Robert Thomas Edmund Mills
In mountain ecosystems with marked seasonality, climate change can affect various processes in soils, potentially modifying long-term key soil services via change in soil organic carbon (C) storage. Based on a four-year soil transplantation experiment in S ...
