Soils from the remote areas of the Amazon Rainforest in Brazil are poorly mapped due to the presence of dense forest and lack of access routes. The use of covariates derived from multispectral and radar remote sensors allows mapping large areas and has the potential to improve the accuracy of soil attribute maps. The objectives of this study were to: (a) evaluate the addition of relief, and veg...

BACKGROUND Against the backdrop of systemic inefficiency in the public health care system and the theoretical claims that markets result in performance and efficiency improvement, developing countries' governments have been rapidly commercializing health care delivery. This paper seeks to determine whether commercialization through an expansion in private hospitals has led to performance improv...

Digital Elevation Models (DEMs) act as an essential input to hydraulic models for the simulation of flood hazard maps. Coarser resolution DEMs are subject higher levels uncertainty, particularly in capturing river-bed bathymetry. The principal aim present study was assess potential use freely available and 1D 2D HEC-RAS modeling approaches mapping four different types river morphology. DEM crea...

Many biochemical processes and dynamics are strongly controlled by terrain topography, making digital elevation models (DEM) a fundamental dataset for range of applications. This study investigates the quality four pan-Arctic DEMs (Arctic DEM, ASTER ALOS DEM Copernicus DEM) within Kalix River watershed in northern Sweden, with aim informing users about when comparing these DEMs. The assessment ...

Recently, a large number of synthetic aperture radar (SAR) images has been introduced into landslide investigations with the growing launch new SAR satellites, such as ALOS/PALSAR-2 and Sentinel-1. Therefore, it is appropriate to develop approaches retrieve three-dimensional (3D) displacements long-term (> 10 years) displacement time series investigate spatio-temporal evolution creep behavior l...

Between 2006 and 2011, the Advanced Land Observing Satellite (ALOS) Phased Array L-type Synthetic Aperture Radar (PALSAR) instrument acquired multi-temporal datasets under several environmental conditions and multiple configurations of look angle and polarization. The extensive archive of SAR backscatter observations over the forest test sites of Krycklan (boreal) and Remningstorp (hemi-boreal)...

The Advanced Land Observing Satellite (ALOS) was launched in 2006, carrying the Phased Array type L-band Synthetic Aperture Radar (PALSAR). Although three years have passed from the start of ALOS PALSAR observation, we know the PALSAR is in operation with greatly stability operation. However, we need to monitor its performance for the future sustainable operation in order to evaluate the tempor...

AIM OF THE STUDY Occlusive dressings for second-degree hand burns in children must prevent infection and promote healing. For good management of analgesia, these treatments often require children to be hospitalized. Our goal was to find an alternative to conventional care protocol that would reduce the number of dressings and therefore the length of hospitalization. We report our experience wit...
