1Hazard and population vulnerability analysis: a step towards landslide risk assessment显示文摘In this paper, an attempt to analyse landslide hazard and vulnerability in the municipality of Pahuatlán, Puebla, Mexico, is presented. In order to estimate landslide hazard, the susceptibility,magnitude(area-velocity ratio) and landslide frequency of the area of interest were produced based on information derived from a geomorphological landslide inventory; the latter was generated by using very high resolution satellite stereo pairs along with information derived from other sources(Google Earth,aerial photographs and historical information).Estimations of landslide susceptibility were determined by combining four statistical techniques:(i) logistic regression,(ii) quadratic discriminant analysis,(iii) linear discriminant analysis, and(iv)neuronal networks. A Digital Elevation Model(DEM)of 10 m spatial resolution was used to extract the slope angle, aspect, curvature, elevation and relief.These factors, in addition to land cover, lithology anddistance to faults, were used as explanatory variables for the susceptibility models. Additionally, a Poisson model was used to estimate landslide temporal frequency, at the same time as landslide magnitude was obtained by using the relationship between landslide area and the velocity of movements. Then,due to the complexity of evaluating it, vulnerability of population was analysed by applying the Spatial Approach to Vulnerability Assessment(SAVE) model which considered levels of exposure, sensitivity and lack of resilience. Results were expressed on maps on which different spatial patterns of levels of landslide hazard and vulnerability were found for the inhabited areas. It is noteworthy that the lack of optimal methodologies to estimate and quantify vulnerability is more notorious than that of hazard assessments.Consequently, levels of uncertainty linked to landslide risk assessment remain a challenge to be addressed.Franny G.MURILLO-GARCíA Mauro ROSSI Francesca ARDIZZONE Federica FIORUCCI Irasema ALCáNTARA-AYALA 2017Journal of Mountain Science2017,14,7:2

5Second Generation Nitrogen Doped Titania Nanoparticles:A Comprehensive Electronic and Microstructural Picture显示文摘A state-of-the-art overview of N-dopant characterizations in nano-TiO_(2)second-generation photocatalysts is provided.The related literature is very rich and sometimes offers contrasting interpretations.Here we critically discuss up-to-date literature results and our own findings,as retrieved by several experimental(BET,HR-TEM,XPS,DRS,HR-XRPD,EXAFS,electrochemical tools)and theoretical(periodic DFT)techniques.Our intent is to pull together outcomes from very different and complementary sources to make an as much as possible coherent picture of the morphological,electrochemical and electronic properties of N-TiO_(2)materials.It is commonly accepted that critical issues to be considered in the design of high-performing N-TiO_(2)photocatalysts are synthetic strategy,defect concentration and chemical nature of the lattice point defects.We focus on the latter two issues,with emphasis on sol-gel prepared materials,according to the specific area of expertise of our group.The problem of the chemical nature of guest N species into the lattice is crucial,as substitutional(N_(s))or interstitial(N_(i))nitrogen place their valence states just above the valence band or deeper into the band gap.Overall,we show how synergism among experimental and theoretical techniques is decisive to disentangle structural,electronic and morphological effects in complex N-doped TiO_(2)matrices.Francesca Spadavecchia Michele Ceotto Leonardo Lo Presti Chiara Aieta Iolanda Biraghi Daniela Meroni Silvia Ardizzone Giuseppe Cappellettia 2014Chinese Journal of Chemistry2014,32,12:1
