Knowledge Dynamics During Planning Practices [PDF]
Ce papier analyse la dynamique des connaissances organisationnelles au cours de pratiques de planification. Il mobilise la notion d'habitus (Bourdieu 1990, 2000) et propose une phase empirique qualitative.Apprentissage organisationnel ; Connaissances ...

High‐Latitude Zonal Jets in the Martian Upper Atmosphere Driven by Non‐Orographic Gravity Waves
Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract We investigate thermosphere responses to non‐orographic gravity waves (GWs) using wind measurements from the Neutral Gas and Ion Mass Spectrometer onboard the Mars Atmosphere and Volatile EvolutioN mission, alongside simulations from the Mars Planetary Climate Model. We focus on zonal jets in high‐latitude regions of the upper atmosphere.

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract Dendritic valley networks on Mars have been cited as evidence for a warm and wet Noachian Mars, permitting rainfall precipitation and surface runoff. However, the climatic conditions required to sustain rainfall on early Mars remain debated.

A novel approach for distinguishing noise and information in forest MLS‐point clouds
Methods in Ecology and Evolution, Volume 17, Issue 5, Page 1595-1605, May 2026.Abstract 3D laser scanning is a cornerstone of modern forest and ecological research, allowing detailed insight into forest structures and dynamics. Although point cloud processing and noise management are crucial steps in the exploitation of LiDAR data, traditional denoising methods are usually based on the assumption of a Gaussian noise distribution,

Dynamiques des connaissances et dynamiques d'innovation
, 2007 Pour aborder les questions d'articulation entre dynamiques des connaissances et dynamiques des innovations, nous nous focalisons sur un métier de l'entreprise dans lequel elles se posent de manière particulièrement aigüe : le métier de recherche. Les métiers de la recherche sont désormais confrontés à une double contrainte.

Local Development and Sustainable Periurban Agriculture: New Models and Approaches for Agricultural Land Conservation [PDF]
Periurban agricultural territories have had to confront many pressures over the last 70 years, ranging from land development pressures emanating from nearby large cities and metropolis to technological change, to the draw of the urban labour market on ...

Géomorphologie dynamique : Bernard Valadas, Géomorphologie dynamique
, 2005 Dans cet ouvrage, la première partie, intitulée « analyse et synthèse », fournit l'essentiel de l'information. Suivent quelques dossiers de documents commentés (textes, tableaux, cartes, etc.). Le bien-fondé de la dernière partie, « repères et outils » apparaît plus discutable : il eut été sans doute plus judicieux d'intégrer son contenu au texte ...

Inspiratory and expiratory tracheal pressures during high‐intensity exercise in harness racehorses
Equine Veterinary Journal, Volume 58, Issue 3, Page 747-757, May 2026.Abstract Background Exercise‐related upper respiratory tract (URT) disorders are common in racehorses. Objective assessment of URT mechanics is essential to quantify degrees of obstruction caused by URT disorders identified upon dynamic endoscopy. Objectives To establish reference values for inspiratory and expiratory tracheal pressures (cmH2O) during ...

Invasive plants optimize leaf nitrogen allocation in photosynthesis
New Phytologist, Volume 250, Issue 3, Page 1522-1534, May 2026.Summary Invasive plants often outcompete co‐occurring native species by expressing acquisitive functional traits that promote high photosynthetic capacity. However, it remains unclear whether these traits are newly evolved in the introduced (‘away’) range or if invaders arrived preadapted with superior traits from their native (‘home’) range.

Spatial Patterns of Shallow Clouds: Challenging the Concept of Defined Regimes
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Tropical shallow clouds are a major source of uncertainty in Earth's climate sensitivity, especially through their spatial arrangement, which global climate models do not represent. Efforts to understand their organization have partly relied on classifying observed scenes, identifying four patterns as archetypal regimes.
