Landslides are one of the most common catastrophic mass flows in mountainous areas. The occurrence of fragmentation leads to the evolution of the integrity and stiffness of the sliding mass. The changes in internal composition caused by basal erosion and entrainment make the dynamic evolution of landslides more complex. To consider these complex processes, physics-based dynamic models are often used to analyze the dynamic characteristics of landslides. However, the proprietary assumptions of dynamic models often limit their application to complex events. A single dynamic model is often not competent for the analysis of landslides with evolving dynamic characteristics. In this study, two dynamic models are effectively integrated according to the evolving characteristics of the landslide. The common effects of basal erosion and entrainment are also considered. The maximum sliding velocity, accumulation range, and erosion depth characteristics of this integrated dynamic model are more consistent with the field than those of the single dynamic model. Under the terrain conditions of this study, within a few seconds of the triggering stage, if the occurrence of disintegration is advanced by 2 s, the maximum impact area will increase by about 3.1% to 4.1%, and the maximum kinetic energy will increase by more than 20%. Simulation results indicate that the changes in the integrity of the landslide body significantly affect the evolution of subsequent landslide dynamic characteristics.

Thrombotic microangiopathy (TMA) is a well-recognized complication of kidney transplantation that leads frequently to allograft failure. This serious outcome depends greatly on the underlying etiology as well as the timing of therapeutic interventions. TMA syndromes may occur with no previous history of TMA, i.e., de novo TMA, mostly due to medications or infection, or more frequently recurs after kidney transplantation i.e., recurrent TMA in patients with ESRF due to the atypical hemolytic uremic syndrome (aHUS). On the other hand, patients with shiga-toxin induced HUS (classic HUS), particularly in childhood has a favorable prognosis. One of the fundamental tools of management of this disease is the genetic screening for abnormal mutations, determination of which will recognize the tools of therapy and consequently outcome of the disease to a large extent. While patients with CFH and CFI mutations have a worse prognosis, other patients with MCP mutations-for example- have a more favorable prognosis. Accordingly, plan of therapy can be thoroughly drawn with a better chance of cure. Unfortunately, the successful use of the biological agent “eculizumab”, an anti-C5 agent, in some of these syndromes is largely impeded by its high cost linked to its use as a life-long therapy. However, a new therapeutic option has been recently admitted ameliorating this drawback and improve the cost-effectiveness balance.

The fjords of eastern Iceland display many landslide landforms. These phenomena, visible by remote observation of satellite images and Digital Elevation Models (DEM), were inventoried then measured and analysed. A total of 290 landslides were recorded in a spreadsheet database and in a Geographic Information System (GIS). For each landslide, location, morphometry (length, width, surface area, thickness, estimated volume, etc.) data, as well as potential control variables, particularly geological (lithology, dip) or explanatory (orientation, age of deglaciation of the slope affected by the landslide) were recorded. These variables and their distribution were studied by spatial and statistical analysis. This study highlights a higher density of landslides in the northern part of the study area, which could be explained by past ice sheet current directions, which would have reinforced the pressure exerted on the slopes leading to the postglacial decompression phenomenon. The over-representation of west- and south-facing landslides leads to the hypothesis of climatic control: the sunnier slopes underwent more rapid deglaciation, which favoured the instability of the slopes. The data collected also suggest that the lithology (Tertiary basalts) is a control variable and the period during which the landslide area is deglaciated an explanatory variable for landslide initiation. The landslides observed are thus part of a paraglacial dynamic of slope instability after their deglaciation.
