The New Science of Unidentified Aerospace-Undersea Phenomena (UAP)
Kevin H. Knuth, Philippe Ailleris, Hussein Ali Agrama +36
After decades of dismissal and secrecy, it has become clear that a significant number of the world's governments take Unidentified Aerospace-Undersea Phenomena (UAP), formerly know…
Towards sustainable space research in France
Alexandre Santerne, Héloïse Meheut, Didier Barret +8
During the 2024's quinquennial scientific roadmap of CNES, a specific group worked on setting recommendations to decrease the environmental footprint of space science activities. T…
On the mechanism of thermal self-regulation of trees: a kind of homeothermic observation
Jean-Baptiste Boulé, Jean de Bremond d'Ars, Vincent Courtillot +6
What is certain is that surface temperatures around the globe vary considerably, regardless of the time scales or underlying causes. Since 1850, we have observed an average increas…
On the effect of the luni-solar gravitational attraction on trees
Jean-Louis Le Mouël, Dominique Gibert, Jean-Baptiste Boulé +5
In this paper, we revisit old electrical measurements conducted on a poplar tree in 2003 (Gibert et al. 2006), which showed the presence of a diurnal electrical signal, attributed…
Fate of nitrogen in French human excreta: current waste and agronomic opportunities for the future
Thomas Starck, Tanguy Fardet, Fabien Esculier
Nitrogen (N) is essential for plant growth and protein synthesis but global reactive N losses, mainly from food systems, induce strong environmental impacts.N losses after human ex…
Phosphorus recycling from human excreta in French agroecosystems and potential for food self-sufficiency
Thomas Starck, Tanguy Fardet, Fabien Esculier
Phosphorus (P) is an essential constituent of life but large P losses from agroecosystems and sanitation systems are a major source of eutrophication in water bodies.These losses a…
Molecular acclimation of Halobacterium salinarum to halite brine inclusions
C. Favreau, A. Tribondeau, M. Marugan +8
Halophilic microorganisms have long been known to survive within the brine inclusions of salt crystals, as evidenced by the change in color for salt crystals containing pigmented h…
On the external forcing of global eruptive activity in the past 300 years
J-L. Le Mouël, D. Gibert, V. Courtillot +11
The decryption of the temporal sequence of volcanic eruptions is a key step in better anticipating future events. Volcanic activity is the result of a complex interaction between i…
A data mining approach for improved interpretation of ERT inverted sections using the DBSCAN clustering algorithm
Kawtar Sabor, Damien Jougnot, Roger Guerin +4
SUMMARY Geophysical imaging using the inversion procedure is a powerful tool for the exploration of the Earth's subsurface. However, the interpretation of inverted images can somet…
Predicting water flow in fully and partially saturated porous media: a new fractal-based permeability model
Nguyen Van Nghia A, Damien Jougnot, Luong Thanh +4
Predicting the permeability of porous media in saturated and partially saturated conditions is of crucial importance in many geo-engineering areas, from water resources to vadose z…
A fractal model for the electrical conductivity of water-saturated porous media during mineral precipitation-dissolution processes
Flore Rembert, Damien Jougnot, Luis Guarracino
Precipitation and dissolution are prime processes in carbonate rocks and being able to monitor them is of major importance for aquifer and reservoir exploitation or environmental s…
Modeling Streaming Potential in Porous and Fractured Media, Description and Benefits of the Effective Excess Charge Density Approach
Damien Jougnot, Delphine Roubinet, Luis Guarracino +1
Self-potential signals can be generated by different sources and can be decomposed in various contributions. Streming potential is the contribution due to the water flux in the sub…
