Soil greenhouse gas emissions (CO2 and N2O) data and metadata of an almond crop diversified with Thymus hyemalis (diversification 1) and with Capparis spinosa (diversification 2). This data comes from WP5 "Environmental impact and delivery of ecosystem services by crop diversification", derived from H2020 Diverfarming project. This workpackage has been designed to provide sound and robust scientific understanding of the benefits and drawbacks of the tailored diversified cropping systems for improvement of the environmental quality and delivery of ecosystem services in each pedoclimatic region. http://www.diverfarming.eu

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.

Experimental data on the rheological and tribological behavior of ionic liquids (ILs) as lubricants of PLA-stainless steel contacts, and of new self-lubricating (PLA + 5 wt.% IL) materials. Five ILs were studied: four aprotic imidazolium ILs with fluorinated anions (LP106: 1-hexyl-3-methylimidazolium hexafluorophosphate; LP104: 1-butyl-3-methylimidazolium hexafluorophosphate; L106: 1-hexyl-3-methylimidazolium tetrafluoroborate; L104: 1-butyl-3-methylimidazolium tetrafluoroborate) and one bio-based protic ammonium IL (DSa: bis(2-hydroxyethyl) ammonium salicylate). The dataset includes IL rheology (viscosity vs. shear rate and temperature, Ostwald-de-Waele and Arrhenius fits), contact angles of the ILs on PLA, friction coefficients and wear rates of PLA-AISI 316L steel pairs under unidirectional pin-on-disk and linear reciprocating sliding (ILs as external lubricants and as internal lubricants in PLA + IL materials), thermal properties (TGA, DSC) of PLA + IL materials, and surface characterization (profilometry, optical microscopy, SEM/EDX) of wear tracks and steel balls., This research was funded by MCIN/AEI/10.13039/501100011033/FEDER, UE (Grant number PID2021-122169NB-I00).
