There is an increasing demand for regional oceanic models capable of simulating the regional ocean circulation. Accurate surface forcing functions are necessary to achieve this goal. Here we present analyses of several data sets covering the contiguous eastern Gulf of Mexico and southeast Atlantic: a) Wind fields resulting from the blending by optimal interpolation (OI) of NCEP, in situ and QuikSCAT winds. These winds show improvements in the coastal region, where orography and coastal boundary layer effects are important and under-resolved. b) Cloud-free SST, created by merging several SST sources using OI. c) Cloud-free chlorophyll, also created using OI. d) Surface drifter trajectories, generated from geostrophic currents and used to track water masses, with application to the Mississippi River outflow subsequent to Hurricane Katrina. e) Multivariate cloud-free products, using SST and chlorophyll, and SST and QuikSCAT winds, to obtain more accurate reconstructions than the monovariate equivalents. We use an EOF-based method, called DINEOF, which has proven to give similar results to OI-based reconstruction but up to 30 times faster, making it very suitable for operational applications. These data sets, originally created for the West Florida Shelf, have been expanded for the Southeast Atlantic Coastal Ocean Observing System (SEACOOS) and for broader environmental applications.

A French adaptation of the UPPS Impulsive Behavior Scale: Confirmatory factor analysis in a sample of undergraduate students

Impulsivity is an important and multifaceted psychological construct. Recently, Whiteside and Lynam (2001) have developed the UPPS Impulsive Behavior Scale that distinguishes four dimensions of impulsivity: Urgency, lack of Premeditation, lack of Perseverance, and Sensation seeking. In the present study, we investigated the psychometric properties of a French adaptation of the UPPS Impulsive Behavior Scale. Two hundred and thirty-four undergraduate students completed the UPPS Scale. Exploratory and confirmatory analyses revealed a four factors solution similar to that found in the original study. Also, the results indicated that there was good to very good internal reliability for the four subscales. [less ▲]

BACKGROUND: The existence of intratissular lymphaticovenous anastomoses has often been suggested, but it has never been demonstrated. This study aims at demonstrating the presence of such anastomoses. METHODS AND RESULTS: The free flap model was used to investigate the drainage of radiolabeled colloid particles whose size prevents direct passage to the blood vessels. The tracer was injected into the muscle or the skin during the surgical procedure. Blood samples were sequentially drawn from the venous pedicle over the 30 minutes that followed the tracer injection. The blood samples were counted using a gamma well-counter. In all 14 patients, the venous blood radioactivity steadily increased over time. Radiochemical analyses performed on the blood samples demonstrated that the radioactivity is related to the labeled colloids and not to free pertechnetate. Planar imaging performed 24 hours after the surgical procedure showed a significant liver uptake, and no accumulation in the area of normal lymphatic relays. CONCLUSIONS: As, in the free flap model, there is no lymphatic drainage through the classical pathways whatsoever, and since the size of the radiolabeled particles prevents them from directly entering the blood stream, the results strongly suggest the presence of functional intratissular lymphovenous anastomoses.

Aim To understand the impact of glacial refugia and migration pathways on the modern genetic diversity of Pinus sylvestris. Location The study was carried out throughout Europe. Methods An extended set of data of pollen and macrofossil remains was used to locate the glacial refugia and reconstruct the migrating routes of P. sylvestris throughout Europe. A vegetation model was used to simulate the extent of the potential refugia during the last glacial period. At the same time a genetic survey was carried out on this species. Results The simulated distribution of P. sylvestris during the last glacial period is coherent with the observed fossil data, which showed a patchy distribution of the refugia between c. 40 degrees N and 50 degrees N. Several migrational fronts were detected within the Iberian and the Italian peninsulas, and outside the Hungarian plain and around the Alps. The modern mitochondrial DNA depicted three different haplotypes for P. sylvestris. Two distinct haplotypes were restricted to northern Spain and Italy, and the third haplotype dominated most of the present-day remaining distribution range of P. sylvestris in Europe. Main concluions During the last glacial period P. sylvestris was constrained under severe climatic conditions to survive in scattered and restricted refugial areas. Combining palaeoenvironmental data, vegetation modelling and the genetic data, we have shown that the long-term isolation in the glacial refugia and the migrational process during the Holocene have played a major role in shaping the modern genetic diversity of P. sylvestris in Europe.
