Conservation de la biodiversité et changement climatique : un nécessaire changement de paradigme - Le cas des poissons migrateurs amphihalins

open access: yesSciences, Eaux & Territoires, 2010
Les espèces les plus menacées font l'objet de plans de restauration visant à retrouver une situation antérieure jugée plus satisfaisante. Mais le changement climatique qui s'est opéré dans certaines régions nécessite de se poser la question de l'utilité ...

Compound Poisson Process with a Poisson Subordinator [PDF]

open access: yesJournal of Applied Probability, 2015
A compound Poisson process whose randomized time is an independent Poisson process is called a compound Poisson process with Poisson subordinator. We provide its probability distribution, which is expressed in terms of the Bell polynomials, and investigate in detail both the special cases in which the compound Poisson process has exponential jumps and ...

RECOVERY OF THIRD-STAGE LARVAE OF ANGUILLICOLA CRASSUS (NEMATODA : DRACUNCULOIDEA) FROM THE FLESH OF FISHES : ASSESSMENT OF A DIGESTIVE MEDIUM AS A TOOL FOR THE STUDY OF FISH PARATENIC HOSTS. EXTRACTION DE LARVES DE TROISIÈME STADE D'ANGUILLICOLA CRASSUS (NEMATODA : DRACUNCULOIDEA) DANS LA CHAIR DE POISSONS : MISE AU POINT D'UNE MÉTHODE PAR DIGESTION POUR L'ÉTUDE DU PORTAGE PARASITAIRE PAR LES POISSONS HÔTES PARATÉNIQUES.

open access: yesKnowledge and Management of Aquatic Ecosystems, 2008
The purpose of this study was to recover third-stage larvae (L3) of Anguillicola crassus alive from the flesh of fishes. Different digestive media have been tested on eel flesh for their efficiency and on living infective third-stage larvae for their ...

Electroweak multi-monopoles

open access: yesNuclear Physics B, 2023
We construct the multi-charge generalizations for the electroweak magnetic monopole solution of Cho and Maison within a wide range of values of the magnetic charge. We use the same ansatz for the axially symmetric fields as the one previously employed to

Self-force as probe of internal structure

open access: yes, 2012
The self-force acting on a (scalar or electric) charge held in place outside a massive body contains information about the body's composition, and can therefore be used as a probe of internal structure.
