This review addresses an often overlooked aspect of elasmobranch osmoregulation, i.e., control of body fluid volume. More specifically the review addresses the impact of changes in blood volume in elasmobranchs exposed to different environmental salinities. Measurement of blood volume in the European lesser-spotted dogfish, Scyliorhinus canicula, following acute and chronic exposure to 80% and ...

Résumé. Lorsque le volume des données est trop important pour qu’elles soient stockées dans une base de données, ou lorsque leur fréquence de production est élevée, les Systèmes de Gestion de Flux de Données (SGFD) permettent de capturer des flux d’enregistrements structurés et de les interroger à la volée par des requêtes permanentes (exécutées de façon continue). Mais les SGFD ne conservent p...

A class of finite volume methods based on standard high resolution schemes, but which allows spatially varying time steps, is described and analyzed. A maximum principle and the TVD property are verified for general advective flux, extending the previous theoretical work on local time stepping methods. Moreover, an entropy condition is verified which, with sufficient limiting, guarantees conver...

INTRODUCTION Dialyzer reprocessing machines have replaced human labor in preparing re-usable dialyzers. It also made the process of total cell volume (TCV) measurement become faster. Nevertheless, there has been a lack of data on efficacy of weight evaluation on TCV by machine compared to volume evaluation by the conventional method. The aim of this study was to evaluate the efficacy of TCV mea...

L’exploitation et la mise à profit des données récupérées à partir de capteurs sont un sujet clef dans beaucoup de domaines d’application. La complexité réside autant dans le volume des flux d’information récupérés, que dans l’interprétation des données. Spécialement, dans le domaine de l’aéronautique, cette tâche est plus ardue vu la quantité des flux récupérés, la nature des données, la compl...

Flux Iattice melting in B12Sr2CaCu20s+~ (Bi-2212) single crystals has recently been studied by various techniques. In this contribution to the 1. Schegolev Memorial Volume we review some experiments and compare their results. Muon-spin rotation and small angle neutron scattenng (SANS) gave the first indications for an abrupt change of the flux Iattice structure along a hne in the B T phase diag...

Vertical movement of lymph from ventral regions to the dorsally located lymph hearts in anurans is accomplished by specialized skeletal muscles working in concert with lung ventilation. We hypothesize that more terrestrial species with greater lymph mobilization capacities and higher lymph flux rates will have larger lung volumes and higher pulmonary compliance than more semi-aquatic or aquatic...

As Gas Insulated DC transmission systems unite the advantages of space saving installation and large transmission capacity this technology is increasingly discussed and investigated today. The main problem in operation with respect to insulation seems to be identified today, which is charge accumulation on the surface of the spacer. These trapped charges can cause a reduction of dielectric stre...

Plant organs such as leaves or petals move as a result of changes in the shape and/or the volume of motor cells. In a similar manner, stomates open and close when the turgor in the guard cells changes. The time scale of such movements ranges from several milliseconds to hours. The most detailed studies of cellular movement have been done with stomata. Stomatal opening requires the uptake of K b...
