The Sahel is affected by a severe drought since the late 1960s. This paper analyses the potential fluctuations of wind on a 44-year period (1951-1994) on the Atlantic coast of West Africa. The change in wind direction could be a witness of a modification on a synoptic scale. The wind velocity recorded in four meteorological stations does not show any rise which could be linked with a continuous aridification. [less ▲]

Large grain melt processed Y-Ba-Cu-O (YBCO) samples have been prepared by seeded and unseeded growth techniques. The current carrying ability within individual grains and across grain boundaries has been investigated and correlated with features in the microstructure of samples fabricated by both techniques. The development of an inhomogeneous, cell-like growth microstructure in seeded samples at distances = 4 mm from the seed is related to a Saturation in inclusion density and volume proportion of Y2BaCuO5 (Y211) particles. A significant decrease in critical current density is associated with this change over a wide temperature range. The resistance of high angle c-axis grain boundaries is observed to depend critically on the magnitude of the injection current whereas the intragranular resistance is not influenced significantly by this variable. Jc of a grain boundary fabricated by unseeded melt growth is estimated to be less than 100 A cm(-2) at 77 K in zero applied field, which is more than two orders of magnitude lower than the intragranular Jc. Field screening measurements suggest that low angle grain boundaries do not form weak links between grains in modest magnetic fields and hence do not present a significant barrier to current flow.

The magnetic anisotropy of rare-earth substituted 2212 materials (Bi(2)Sr(2)Ca(0.8)RE(0.2)Cu(2)O(x) with RE = Gd, Dy, Ho, Er) is put into evidence. Superconducting powder dispersed in epoxy resin is ... [more ▼]

The magnetic anisotropy of rare-earth substituted 2212 materials (Bi(2)Sr(2)Ca(0.8)RE(0.2)Cu(2)O(x) with RE = Gd, Dy, Ho, Er) is put into evidence. Superconducting powder dispersed in epoxy resin is oriented under an external magnetic field (4 T) in a direction that depends on the nature of the rare-earth used in the substitution. Both directions of observation (parallel or perpendicular to the field) were investigated. Splitting of (00l) peaks is neatly observed and discussed. [less ▲]

Nous rapportons un cas rare de sarcome de l'artère pulmonaire, diagnostiqué chez un patient souffrant de décompensation cardiaque. L'échographie cardiaque transoesophagienne et la tomodensitométrie thoracique ont permis un diagnostic précis de masse dans l'artère pulmonaire. Le traitement instauré fut une résection chirurgicale, aidée par une circulation extra corporelle et un arrêt cardiaque en hypothermie, et l'analyse anatomopathologique de la pièce réséquée a décris la présence d'un sarcome peu différencié de l'artère pulmonaire. Quoiqu'un traitement postopératoire complémentaire par chimiothérapie a été entrepris, le pronostic vital du patient reste sombre à moyen terme au vu des données de la littérature. [less ▲]

Five goat latissimus dorsi muscles (LDM) were submitted to a progressive chronic electrostimulation program to reach an integrated understanding of the fast-to-slow transformation process in large mammals. LDM were regularly sampled and followed during a period of 8 months. Each sample was simultaneously assessed for histoenzymological study, myosin and LDH isoforms and bioenergetic capacities [NADH dehydrogenase cytochrome c oxidoreductase (NADH Cyt c OR), succinate dehydrogenase cytochrome c oxidoreductase (Succ Cyt c OR), cytochrome c oxidase (Cyt c Ox) and LDH]. Such muscles were also tested with and without completion of II to I transformation for their mechanical properties in isometric and isotonic strain gauge testing. The conversion of fast-to-slow myosin monitored by heavy chain (HC I) and light chain slow component (LC2s) began a few days after stimulation and was almost 100% after 100 days. The H-LDH isoforms evolved similarly but did not reach 100% conversion after 200 days. The activity of respiratory chain oxidases increased within 36 h but to a variable extent and peaked after 32 days, corresponding to a 75% transformation of myosin compared to initial levels. NADH Cyt c OR, Succ Cyt c OR, and Cyt c Ox, respectively increased 10-, 5- and 5-fold. These activities then significantly decreased before the completion of the myofibrillar transformation and reached a plateau with stable activities that remained 2- to 3-fold higher than the unstimulated LDM. LDH activity sharply decreased until day 62 (5-fold) and then plateaued. Functionally, muscle showed a reduced speed of contraction and moderate reduction in power output but had become fatigue-resistant. This study documents the transformation process in large mammals and suggests the dynamic relation between workload, aerobic-anaerobic metabolism and the contractile myofibrillar system. [less ▲]

A preliminary telemetry investigation on the obstacles to anadromous Salmonids migration in spawning streams of the Belgian Ardennes (river Meuse bassin)

In the course of the 'Meuse Salmon 2000' programme aiming at the restoration of the Atlantic salmon Salmo salar and sea trout Salmo trutta in the River Meuse Basin, most large dams are progressively equipped with fishways to restore the free circulation of spawners between the North Sea and the first major spawning streams, the River Ourthe and its tributaries. Spawners entering the River Ourthe would still be confronted to so-called minor obstacles, aiming at water regulation for tourism purposes but of which the actual impact on fish migration has never been investigated. In order to test for the actual free-circulation of salmonid spawners in the upper River Ourthe and to locate potential spawning grounds, a probe fish (489 mm FL male sea trout) was tagged with an intraperitoneally implanted radio-transmitter. From the 18th of ovember 1995 onwards, the trout was tracked in a part of the river (44 km upstream of the confluence) which was thought to be devoid of any major obstacle to fish migration. Three days after its release, the trout had migrated over 6 km up to a small weir (1.8 m high). During four consecutive days, the trout was consistently located downstream of the weir but no successful climbing was observed, reflecting the poor efficiency of the central fishpass under dry weather conditions during summer and autumn. The trout then settled in a deep run habitat, 150 m downstream of the weir and no upstream excursion was recorded until the first major rise of water level, four weeks later, even when the weir was opened for water regulation purposes. When the water level was maximum (24th of December), the trout moved upstream of the weir and migrated over 28 km during the next 72 hours up to a spot identified as a potential spawning redd from habitat features, and where it was consistently located till the 31st of December. These results, though most preliminary, clearly indicate that even minor obstacles may cause a substantial lag in trout migration of which the impact on spawning success remains to be determined. Since similar minor man-made obstacles are most frequent in the salmonid spawning streams of the Belgian Ardennes, it is thus uncertain that migratory trout having successfully climbed the major obstacles since the North Sea would find their way to the spawning redds. As a corollary, it is suggested that more detailed case studies should be undertaken, ideally via the use of telemetered probe-fish, in order to provide management policies that would represent a suitable compromise between users of water resources with apparently conflicting interests (water regulation, tourism, nature conservancy).
