Coupling of a field-scale crop model and a 3D architectural root model
EGU General Assembly 2018, EGU2018, ViennaVienna, Austria, 8 Apr 2018 - 13 Apr 20182018-04-082018-04-13
Especially under unfavorable environmental conditions such as dry conditions or nutrient limitation, the accurate prediction of the root growth and related resource uptake efficiency is crucial to accurately simulate crop growthand development. With the aim to improve the prediction of crop growth, we coupled a 1D field-scale crop-soil water model (running in the modeling framework Simplace) with the 3D architectural root model CRootBox ona daily time step.

KEYLINK model: a short introduction to its use and usefulness
Soil biodiversity and European woody agroecosystems, BioLink2018, GranadaGranada, Spain, 14 Mar 2018 - 16 Mar 20182018-03-142018-03-16
Most existing ecosystem models do not represent properly the structure of the soil (Vereeckenet al., 2016), which is indispensable for connecting the food web with its role controlling soilcarbon (C) biogeochemical cycle. KEYLINK is a new model which integrates knowledge aboutsoil structure and how this affects soil organic matter (SOM) dynamics (transformations,mineralization and stabilization), hidrology and the structure of the soil food web.Using quite affordable parameters about climate, initial soil carbon pools and rates of key bioticprocesses (e.g. [...]

Investigation of Physical and Electrochemical Properties of PILs in HT-PEFCsHui Hou, Jürgen Giffin, Alessandro Mariani, Carsten KorteForschungszentrum Jülich GmbH, IEK-3Wilhelm-Johnen-Straße, 52428 Jülich, Germany h.hou@fz-juelich.deThere is an increasing requirement in the field of polymer membrane fuel cell (PEFCs) for new proton conducting membrane electrolytes that can be operated at the temperature of around 100 °C and with low water activity. The proton con¬duc¬tivity of perfluorinated polymers with sulfonic acid groups relies on sufficient water swelling. [...]

The Jülich Electric Dipole Moment (JEDI) Collaboration is presently preparing for a first direct measurement of the deuteron Electric Dipole Moment (EDM) in the COoler SYnchrotron (COSY). A non-vanishing EDM signal would provide a new source for $CP$ violation which could answer the mystery behind the matter abundance in the universe. [...]
