Climate change impacts on hydropower in the Swiss and Italian Alps.

This paper provides a synthesis and comparison of methodologies and results obtained in several studies devoted to the impact of climate change on hydropower. By putting into perspective various case studies, we provide a broader context and improved understanding of climate changes on energy production. We also underline the strengths and weaknesses of the approaches used as far as technical, physical and economical aspects are concerned.

[Multilevel atherosclerotic lesions of the lower limbs. Simultaneous surgical and endovascular approach. A case report].

Surgical treatment of femoro-popliteal atherosclerotic occlusion usually consists in a femoro-distal bypass. However, the associated presence of proximal lesions that reduce prosthesis inflow, or of distal lesions that increase resistances may be decisive factors in determining the outcome of the revascularisation. Frequently, an iliac or common femoral artery stenosis can be treated with an endovascular technique prior to surgery, thus increasing the bypass inflow that is going to be created.
