High energy photons from blazars can initiate electromagnetic pair cascades interacting with the extragalactic photon background. The charged component of such is deflected and delayed by magnetic fields (EGMF), reducing thereby observed point-like flux leading potentially to multi degree images in GeV range. We calculate fluence 1ES 0229+200 as seen Fermi-LAT for different EGMF profiles using a Monte Carlo simulation cascade development. non-observation suggests that fills at least 60%...

Beijing is one of the most water-stressed cities in world. Due to over-exploitation groundwater, region has been suffering from land subsidence since 1935. In this study, Small Baseline InSAR technique employed process Envisat ASAR images acquired between 2003 and 2010 TerraSAR-X stripmap collected 2011 investigate region.

The Daguangbao mega-landslide (China), induced by the 2008 Wenchuan earthquake (Mw = 7.9), with an area of approximately 8 km2, is one largest landslides in world. Experts predicted that potential risk and instability landslide might remain for many decades, or even longer. Monitoring activity such a large hence critical. Terrain Observation Progressive Scans (TOPS) mode from Sentinel-1 satellite provides us up-to-date high-quality Synthetic Aperture Radar (SAR) images over wide ground...

Early warning systems (EWSs) to detect and monitor landslides are a great challenge. They important due the high cost of catastrophic challenging because difficulty in identifying diverse range landslide-triggering factors. While there has been very limited number successes, recent advances Earth observation (EO) from ground, aircraft, space have dramatically improved our ability active landslides. A growing body geotechnical theory suggests that prefailure behavior can offer clues location...

For neutrinos streaming from a supernova core, dense matter suppresses self-induced flavor transformations if the electron density ${n}_{e}$ significantly exceeds neutrino ${n}_{\ensuremath{\nu}}$ in conversion region. If is comparable to ${n}_{\ensuremath{\nu}}$, one finds multiangle decoherence, whereas standard transformation behavior requires that region safely above ${n}_{e}$. This condition need not be satisfied early phase after core bounce. Our new effect subtle consequence of...

In recent years, there was an increasing number of studies focusing on rockfalls due to their impacts social and sustainable development. This work carries out a three-dimensional (3D) simulation at cultural heritage site nearby the village Cortes de Pallás (Valencian Community, East Spain). The is based data collected previously, during emergency declaration occurrence considerable rockfall (7980 m3) southern bank reservoir, 6 April 2015. hydroelectric power plant damaged, main access road...

The natural stone industry generates large amounts of industrial waste every year. Limestone powder produced by the activity this is dumped into landfills, generating an environmental impact that could be reduced using as a binder in building materials. In present work, use by-product addition for soil improvement clayey soils has been studied. tested soft clay from southeastern Spain, which mixed adding 5, 10, 15, 20, and 25% dry limestone dust total weight soil. additive have...
