This paper investigates the use of time series of ALOS/PALSAR-1 and COSMO-SkyMed data for the soil moisture retrieval (mv) by means of the SMOSAR algorithm. The application context is the exploitation of mv maps at a moderate spatial and temporal resolution for improving flood/drought monitoring at regional scale. The SAR data were acquired over the Capitanata plain in Southern Italy, over whic...

Laser Profiler (LP) data from aerial laser surveys have been increasingly used as topographical inputs to numerical simulations of flooding and inundation in river basins. LP data has great potential for reproducing topography, but its effective usage has not yet been fully established. In this study, flooding and inundation are simulated numerically using LP data for the Jobaru River basin of ...

The Midlands and South -west of England are represented by a long oak tree -ring chronology spanning approximately 4500 -3900 BC (calibrated radiocarbon dates). The wood on which it is based originates in a technologically advanced trackway crossing the low -lying Somerset Levels, in a coastal submerged forest probably killed by rising sea -level, and in flood -plain oaks washed down the River ...

The study analyses strengths and weaknesses of different methods for calculating the economic importance of forest products extracted by rural populations. The results show that methods frequently used by scholars are subject to serious uncertainty. The study is based on a 1-year survey in two flood plain villages in the Peruvian Amazon. Different methods were studied in relation to local extra...

The classical role of a firewall consists in protecting a computer network against attacks from the outside world, especially the Internet. Firewalls are often expensive, hard to configure and they are comprehended only by experts. Sometimes the level of security is too high to use a firewall, and information flow has not to be “online”. Here we propose to use “floodgates” as described in the f...

Blastocerus dichotomus, the marsh deer, is the largest Brazilian Cervidae species. The species is endangered because of hunting and loss of its natural habitat, i.e., flood plain areas, because of hydroelectric power station construction and agricultural land expansion. In the present study, we tested 38 microsatellite loci from four Cervidae species: Odocoileus virginianus (7), Rangifer tarand...

OBJECTIVE To investigate the rate of neural tube defects (NTDs) and their relation to gender, maternal age, consanguineous marriage, season, and drug consumption in Birjand, Iran. METHODS This research was carried out on 16,785 live or stillborn newborns in Birjand, Iran from April 1997 to December 2001. RESULTS The rate of NTDs was 2.97 per 1000. This rate was 1.97 per 1000 in males, and 3...
