The authors present an assessment of risk from river bank erosion in the Brahmaputra river basin. The concept of risk is conceptualised in the context of socio-economic vulnerability, and the potential for exposure to hazard. By addressing both the physical hazard and the variations across the socio-economic surface the approach presented attempts to spatially combine these parameters to provid...

BACKGROUND The tidal flat is one of the important components of coastal wetland systems in the Yellow River Delta (YRD). It can stabilize shorelines and protect coastal biodiversity. The erosion risk in tidal flats in coastal wetlands was seldom been studied. Characterizing changes of soil particle size distribution (PSD) is an important way to quantity soil erosion in tidal flats. METHOD/PRI...

As starting hypothesis, we argue that the erosion of safe sex practices for people having frequent change of sexual partner might be explained in terms of two mechanisms: instrumental conditioning through “reward” (greater sexual pleasure) following unprotected sex and misperception of the risk to become infected by HIV due to low infectivity of HIV and long delays (long latency and incubation ...

Data integration is a very important strategy to obtain optimum solutions in geo-scientific analysis, 3D scene modelling and visualization. This paper mainly focuses on the integration of GIS-data, stereo aerial imagery and DSM to derive automatically wind erosion obstacles in the open landscape to enhance the Digital Soil Science Map of Lower Saxony in Germany. The extracted wind erosion obsta...

INTRODUCTION Most men with erectile dysfunction are initially offered systemic therapy with a phosphodiesterase type 5 inhibitor, and then a choice of intracorporeal injection or intraurethral treatment. If these initial treatments fail or are rejected, penile prosthesis implantation is usually the third-line treatment option. The technology for penile prosthesis has been evolving, and it has b...
