Hail precipitation is characterized by enhanced spatial and temporal variability. Association Nationale d'Etude et de Lutte contre les Fléaux Atmosphériques (ANELFA) installed hailpad networks in the Atlantic and Midi-Pyrénées regions of France. Historical data of hail variables from 1990 to 2010 were used to characterize variability. A total of 443 stations with continuous records were chosen ...

A total of 302 serum samples collected from Chitawan (159) and Mustang (143) districts of Nepal were included in this study. Anti-toxoplasma antibody was detected using micro-latex agglutination (MLA) and ELISA methods. An overall positive rate was found to be 57.9%. The positive rate in Chitawan was significantly higher (64.1%) (less than 1,000 m altitude) compared to that in Mustang (51.0%) (...

We present an analysis related to the evaluation of Morison and transverse force coefficients in case a submerged square barrier subject action solitary waves. To this purpose, two-dimensional experimental research was undertaken wave flume University Calabria, which rigid provided by discrete battery pressure sensors determine horizontal vertical hydrodynamic forces. A total set 18 laboratory ...
