Many species of gobiid fishes adhere to surfaces using a sucker formed from fusion of the pelvic fins. Juveniles of many amphidromous species use this pelvic sucker to scale waterfalls during migrations to upstream habitats after an oceanic larval phase. However, adults may still use suckers to re-scale waterfalls if displaced. If attachment force is proportional to sucker area and if growth of...

Abstract Central counterparty (CCP) default waterfalls act as the last lines of defense in over-the-counter markets by managing and allocating resources to cover payment defaults. This article examines impact variations waterfall design on financial system losses presence network dependencies frictions cleared noncleared portion system.

Note: To follow this note and especially to get definitions of concepts as lower catchment basin, FOZ, dual geodesic reconstruction, I STRONGLY recommend to read the following documents available on my Web page (http://cmm.ensmp.fr/~beucher/publi.html): P algorithm, a dramatic enhancement of the waterfal transformation (http://cmm.ensmp.fr/~beucher/publi/P-Algorithm_SB_BM.pdf, in particular, pa...

Abstract: This study sought to identify the ichthyofauna composition of Muzambinho River, an upland tributary Paraná River. We also investigate whether waterfalls in region can serve as barriers dispersal fish species. For this purpose, collections were carried out at 34 points on River using different techniques. In all, 37 species recorded, some which endemic, and majority native. Among these...
