Méthodes de calcul pour la conception des systèmes de protection cathodique des structures longilignes Computing Methods for Designing Cathodic Protection Systemes for Elongate Stuctures

Oil & Gas Science and Technology, 2006
Les différentes structures longilignes qu'utilise l'industrie des hydrocarbures sont, dans la plupart des cas, soumises à un système de protection cathodique par anodes sacrificielles ou par courant imposé.

Mesomorphic and Thermal Behavior of Symmetric Bent-Core Liquid Crystal Compounds Derived from Resorcinol and Isophthalic Acid

Crystals, 2021
Bent-core liquid crystals (BCLC) have been widely studied as a result of their unusual polar and chiral properties. Similar to calamitic and discotic molecules, BCLC molecules also exhibit nematic phases, besides other higher order mesophases. The aim of

Un outil de dimensionnement des filets pare-pierres : le logiciel ECRANS [PDF]

Sciences, Eaux & Territoires, 2010
En zone de montagne, les chutes de blocs rocheux sont nombreuses et peuvent causer des dégâts et parfois même, faire des victimes. Afin d'assurer la protection des usagers et des biens, il est nécessaire de mettre en place des techniques de protection ...

Simulation de la structure optimale des hêtraies de protection contre les chutes de pierres | Simulation of the optimal structure of beech forests protecting against rockfall [PDF]

Schweizerische Zeitschrift fur Forstwesen, 2008
Adequate management practices to attain the profiles specified in the Swiss guidelines for the management of mountain protection forests are not always unequivocally clear. This applies among others for beech forests that have a protective function against rockfall.

A Rhodococcal Transcriptional Regulatory Mechanism Detects the Common Lactone Ring of AHL Quorum-Sensing Signals and Triggers the Quorum-Quenching Response

Frontiers in Microbiology, 2018
The biocontrol agent Rhodococcus erythropolis disrupts virulence of plant and human Gram-negative pathogens by catabolizing their N-acyl-homoserine lactones.

A Flavor Lactone Mimicking AHL Quorum-Sensing Signals Exploits the Broad Affinity of the QsdR Regulator to Stimulate Transcription of the Rhodococcal qsd Operon Involved in Quorum-Quenching and Biocontrol Activities

Frontiers in Microbiology, 2019
In many Gram-negative bacteria, virulence, and social behavior are controlled by quorum-sensing (QS) systems based on the synthesis and perception of N-acyl homoserine lactones (AHLs).

Residual protection on a wharf structure following application of impressed current cathodic protection [PDF]

MATEC Web of Conferences, 2019
Recent studies have suggested that residual protection is afforded to structures following the application of impressed current cathodic protection (ICCP), in some cases for significant periods of time, while others for periods of only a few days.

Analyse de l’aléa « lave torrentielle » sur le cône de déjection du torrent du Rioulong (Hautes-Pyrénées) : une approche par scénarios [PDF]

Sciences, Eaux & Territoires, 2010
En France, plus de quatre mille communes seraient menacées par les laves torrentielles. Phénomènes difficilement prévisibles, la protection contre les risques qu’elles génèrent repose donc essentiellement sur des mesures de prévention.
