This research provides a first assessment of the location of air pockets in a case study from the literature by using the developed AirSWMM. A pressure-driven analysis is implemented in the source code of AirSWMM(v2.0) to better simulate the nodal demand since this feature was not originally included in SWMM. Pressure-head results for different spatial discretisations are compared with collected field data to assess the best compromise between spatial discretisation and the results’ accuracy. The recommendations from international guidelines for the location of air release devices are compared to the predicted air pocket locations to assess if the numerical estimates are in agreement with the empirical evidence.

Conjugated polymers have been developed since the past 30 years, but only recently, applications to optoelectronic devices such as thin film transistors, light emitting diodes, organic lasers and organic solar cells have become close to commercial applications. Regarding solar cells, a new class of low band gap polymers are showing promising results in power conversion efficiency. After our initial experiments and SANS measurements, we have chosen PCPDTBT as the best candidate for quasielastic experiments. The importance of temperature processing on the control of the molecular dynamics (and final structure) of the polymer and its impact on the optoelectronic performance is the driving force for the proposed experiment. Our aim is to explore the molecular motions of PCPDTBT on a broad range of temperatures, from 10K to 450K, which are tipically used in annealing cycles during processing of the active layer of organic solar cells. We expect to characterize the molecular motions (activation energy, characteristic times), and in detail: Debye-Waller, alpha and beta relaxations, and eventually, methyl group rotations (at the end of side chains).

Datasets with all properties measured during three crop cycles of an experiment developed to assess the efficiency of intercropping between broccoli and fava bean to enhance crop productivity, soil health and carbon sequestration and storage and reduce soil greenhouse gas emissions and the use of external inputs. We compared a broccoli monocrop (Brassica oleracea var. italica Plenck), a fava bean monocrop (Vicia faba L.) and different broccoli-fava bean intercropping systems in three winter crop cycles: 2018/2019, 2019/2020 and 2020/2021. The intercropping systems were: i) mixed intercropping (alternation within the same row of broccoli and fava bean plants), row intercropping 1:1 (combination of alternate rows of broccoli - fava bean) and row intercropping 2:1 (combination of two rows of the broccoli crop and one row of fava bean)., This research was funded by the Project AsociaHortus granted by the Spanish Ministry of Science and Innovation (AGL2017-83975-R).
