2020 Remote Sensing  
The exploitation of surface deformation velocity derived from satellite synthetic aperture radar interferometry (InSAR) is a consolidated and suitable procedure for the recognition of active landslides  ...  In this paper, different velocity datasets derived from both ascending and descending Sentinel-1 data are employed to analyze the surface ground movement of the Huangshui region (Northwestern China).  ...  Ascending and descending acquisitions of Sentinel-1 mission were combined to generate two-dimensional displacements and thus to detect and map active loess landslides.  ...

2021 Remote Sensing  
This method is applied to identify the potential geohazard areas in a mountainous region in northwest China (Lajia Town in Qinghai province) using 73 and 71 Sentinel-1 images from the ascending and descending  ...  orbits, respectively, and an urban area (Dongguan City in Guangdong province) in south China using 32 Sentinel-1 images from the ascending orbit.  ...  The acquisition time and basic parameters of the used Sentinel-1 data are shown inTables 2 and A1. Figure 7 . 7 Flowchart of the MT-InSAR data processing.  ...

2011 Parasitology Research  
The present study emphasizes that use of larval cultures allows a proper assessment of mixed strongyle populations in horses and it might represent an useful tool for further investigations into the epidemiology  ...  Further larval cultures were performed from pooled positive samples for the identification of third-stage larvae (L3) of strongyle nematodes.  ...  ACKNOWLEDGEMENTS This work was supported by a grant of the Romanian National Authority for Scientific Research and Innovation, CNCS -UEFISCDI, project number PN-II-RU-TE-2014-4-1432.  ...
