De quoi les déterritorialisation et reterritorialisation sont‐ils la somme?: méta‐analyse des usages et entendements du triptyque territorialisation‐déterritorialisation‐reterritorialisation en géographie

open access: yesCanadian Geographies / Géographies canadiennes, Volume 70, Issue 1, Spring / printemps 2026.
Résumé Cet article s'intéresse aux multiples usages et entendements des processus de territorialisation, de déterritorialisation et de reterritorialisation en géographie. Examinant un vaste corpus d'articles francophones et anglophones, il cherche à dégager les différentes approches et sous‐approches de ces notions par les géographes, ce afin d ...

Eine Perspektive zu interdisziplinären Ansätzen in der Chemotaxis(forschung)

open access: yesAngewandte Chemie, Volume 137, Issue 47, November 17, 2025.
Chemotaxis ist die Bewegung individueller Agenten hin zu oder weg von einem chemischen Stimulus. Dieses Phänomen wird in den verschiedensten Fachbereichen untersucht, von Biologie hin zu Physik und auch im Ingenieurwesen. Dieses Perspektivpapier zielt darauf ab, neue Entwicklungen im Feld darzustellen und die Vereinheitlichung von Terminologie zu ...

Risk of Flame Acceleration Due to Accumulation of Unburnt Volatiles in Zero-Gravity Condition

open access: yesSci
This paper investigates the influence of ventilation conditions, including oxidizer flow speed and oxygen concentration, on major species composition in favor of estimating a risk of flame acceleration at reduced gravity. A two-step chemical reaction for

Modélisation d'un écoulement diphasique dans une succession de pores Modeling Two-Phase Flow in a Succession of Pores

open access: yesOil & Gas Science and Technology, 2006
Une succession de pores du milieu poreux est schématisée par des conduits bidimensionnels périodiques à pores rectangulaires. Le fluide mouillant est supposé piégé dans les anfractuosités ou pores de ces conduits et les équations décrivant l'écoulement ...

Preliminary test on modified clays for seawater resistant drilling fluids [PDF]

open access: yes, 2015
The quality of a drilling fluid declines in salt water conditions. An engineered clay (HYPER clay) was developed for geosynthetic clay liners with enhanced resistance to aggressive conditions.

Genesis of d'Alembert's paradox and analytical elaboration of the drag problem

open access: yes, 2008
We show that the issue of the drag exerted by an incompressible fluid on a body in uniform motion has played a major role in the early development of fluid dynamics.

Laserentfernungsmessungen zum Mond: Das Erde‐Mond‐System als Gravitationslabor

open access: yesPhysik in unserer Zeit, Volume 56, Issue 6, Page 281-286, November 2025.
Seit über 50 Jahren wird das Erde‐Mond‐System mit Lasern exakt vermessen. Es geht dabei um hochempfindliche Tests der Relativitätstheorie und unter anderem um die Frage, ob das Äquivalenzprinzip wirklich universell und materialunabhängig ist. Hochgenaue Abstandsmessungen mit ultrakurzen Laserpulsen sollen diese Frage klären.

Clogging Analysis in Drip Irrigation Systems: CFD and DEM Approaches

open access: yesIrrigation and Drainage, Volume 74, Issue 4, Page 1395-1409, October 2025.
ABSTRACT Clogging represents a critical challenge that undermines the efficiency and sustainability of drip irrigation systems by inducing uneven water distribution and increasing maintenance requirements. In this study, the phenomenon of clogging in drip emitters was investigated via computational fluid dynamics (CFD) in conjunction with the discrete ...

The crucial role of meshing in computational fluid dynamics simulations for organic geometries in paleobiology: Describing fluid dynamics performance through best practices

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 10, Page 2170-2194, October 2025.
Abstract Computational fluid dynamics (CFD) has become an essential tool for studying fluid interactions in biological systems. While widely used in engineering, its application in the natural sciences, particularly in paleobiology, remains limited due to the challenges of meshing complex organic geometries.
