Atmospheric aerosols interact with sun light by scattering and absorbing radiation. By changing irradiance of the Earth surface, modifying cloud fractional cover and microphysical properties and a number of other mechanisms, they affect the energy balance, hydrological cycle, and planetary climate [IPCC, 2007]. In many world regions there is a growing impact of aerosols on air quality and human...

Stormwater source control regulations are rapidly diffusing in many countries. Most of these are provisions that limit runoff rates at the parcel-scale, although some references indicate some negative side effects, at the catchment-scale, for this form of regulation. In this paper, we compare, at that scale, the effects of several runoff rate and runoff volume provisions, using a hydrological m...

background: it has been demonstrated that performing a mock embryo transfer (et) significantly improves the pregnancy rate in ivf cycles. the mock et could be performed prior to the stimulation cycle or immediately before real et. the problem of the first procedure is the possibility of variation in the uterine position and or cervico�uterine angle. objective: the purpose of this study was to d...

Numerical models are being used to simulate the response of hydrological basins to meteorological events both for decision making process in case of severe weather, as well as for the management of water resources and the environment. Nevertheless, it appears increasingly important to understand the possible effects of observed climate changes on the hydrological system, and in order to simulat...
