Body mass index (BMI) and mortality in old adults from the general population have been related in a U-shaped or J-shaped curve. However, limited information is available for elderly nursing home populations, particularly about specific cause of death. A systematic PubMed/EMBASE/CINAHL/SCOPUS search until 31 May 2014 without language restrictions was conducted. As no published study reported mortality in standard BMI groups (Funding agencies: Baxter; Abbott; Fresenius-Kabi; Pfizeer; Nestle; Sanofi; Novo Nordisk; Boehringer Ingelheim; Merck; BMS; Feinstein Institute for Medical Research; Janssen/JJ; National Institute of Mental Health (NIMH); National Alliance for Research in Schizophrenia and

Effectively reducing cumulative impacts on marine ecosystems requires co-evolution between science, policy and practice. Here, long-term social–ecological changes in the Baltic Sea are described, illustrating how the process of making the ecosystem approach operational in a large marine ecosystem can be stimulated. The existing multi-level governance institutions are specifically set up for dealing with individual sectors, but do not adequately support an operational application of the ecosystem approach. The review of ecosystem services in relation to regime shifts and resilience of the Baltic Sea sub-basins, and their driving forces, points to a number of challenges. There is however a movement towards a new governance regime. Bottom-up pilot initiatives can lead to a diffusion of innovation within the existing governance framework. Top-down, enabling EU legislation, can help stimulating innovations and re-organizing governance structures at drainage basin level to the Baltic Sea catchment as a whole. Experimentation and innovation at local to the regional levels is critical for a transition to ecosystem-based management. Establishing science-based learning platforms at sub-basin scales could facilitate this process.

In this paper a methodology for the numerical solution of frictional heating problems is presented. The penetration process of a steel nail into a steel support is used as a reference case for the axisymmetric formula- tion. The problem is characterized by a big amount of heat generated by frictional dissipation. Such thermal heating plays an important role in the anchoring of the nail and in the pull-out resistance. Due to the short time transient the heat is stored inside a very thin layer around the contact surfaces. In order to minimize the computational effort a local lagrangian thermal discretisation is used in the heat affected zone. Since a weakly-coupled solution is provided, thermal and mechanical discretisations around contact surfaces are different and only geometrically linked. The adopted weakly-coupled solution solves separately the thermal and the mechanical fields, following a staggered procedure.
