This study presents an extended vertical grid for the regional atmospheric model COSMO, used for numerical weather prediction, reaching up to 33 km. The extended setup has been used to stably simulate eleven months in a domain covering central and northern Europe. Temperature and relative humidity have been validated using 5 radio sonde data in polar and temperate latitudes, focussing on the st...

Synthetic aperture radar (SAR) interferometry is a powerful technology for detection and monitoring of slow terrain movements. Extraction of this information is a complex task. The persistent scatterer pair (PSP) approach was recently proposed to overcome limitations of standard persistent scatter interferometry. The PSP method exploits only the relative properties of neighboring points to avoi...

The Cosmo.Lab project, financed by the European Community, has the object of developing AstroMD, a tool of visualization and analysis of astrophysical data. AstroMD responds to the requirements proposed by several research fields: data coming from cosmological simulations, from observational catalogues and extended objects like radiosources or clusters of galaxies. AstroMD exploits also the mos...

BACKGROUND Mosquitoes transmit serious human diseases, causing millions of death every year. Vector control is facing a threat due to the emergence of resistance to synthetic insecticides. Insecticides of botanical origin may serve as suitable alternative biocontrol techniques in the future. Nine different locally available medicinally important plants suspected to posse larvicidal property wer...

We studied the seasonal activity of Bombus pennsylvanicus sonorus Say in subtropical conditions of the Mexican Central Plateau. Monthly during 1998, we recorded caste of active individuals (inferred form corporal size measured as wing length), presence and activity of reproductive individuals, and mating activity. Also, we recorded the flower plants used as resources. Subtropical conditions of ...

WHEN certain typical plants, such as Cosmos (Cosmos bipinnatus), Salvia (Salvia splendens) and soybeans (Soja max) are exposed to a short photoperiod (7to 8-hour day) and a relatively long one (14to 15-hour day) they exhibit conspicuous differences in rate of growth, time of sexual reproduction and greenness of foliage. The short-day soybean plants, for instance, are lighter in color early in t...
