Blue-green roofs as nature-based solutions for urban areas: hydrological performance and climatic index analyses.

The water-regulating capacity of nature-based solutions (NBSs) plays a crucial role in providing a full range of ecosystem services and enhancing the resilience of urban systems. This work focuses on the hydrological performance of a particular NBS, the so-called blue-green roof (BGR). The BGR is designed to collect infiltrated rainfall in a water storage layer beneath the soil to support vegetation maintenance, enhance evapotranspiration and cooling, and minimize runoff and drainage system load.

Integrating spatially-and temporally-heterogeneous data on river network dynamics using graph theory.

The study of non-perennial streams requires extensive experimental data on the temporal evolution of surface flow presence across different nodes of channel networks. However, the consistency and homogeneity of available datasets is threatened by the empirical burden required to map stream network expansions and contractions. Here, we developed a data-driven, graph-theory framework aimed at representing the hierarchical structuring of channel network dynamics (i.

[Traumatic motherhood in Covid-19 times].

In the context of maternal vital emergency due to Covid-19, dire situations of birth questioned the health practitioners of a neonatal intensive care unit. How can mothers take care of their baby when their own life has been threatened ? The analysis of two clinical cases underlines the importance of talking for these mothers who have been through disastrous experiences, which could lead to a post-traumatic stress disorder. Restoring a connection to outside reality thanks to psychological care in the acute post-trauma period helps these mothers take care of their child.
