2. 1. Hip fracture - Mortality and residual lifetime risk of fractures

   Author : My von Friesendorff; Ortopedi - klinisk och molekylär osteoporosforskning; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hip fracture; women; men; sex; age; survival; mortality; subsequent fracture; fracture risk; residual lifetime; cause of death; long term;

   Abstract : Hip fracture is the most severe clinical manifestation of bone fragility. Hip fracture predominantly affects an already frail population and is associated with multi-cause morbidity and high mortality. Improved knowledge of long-term outcome is essential in order to improve future care and prevention of both fracture and its complications. READ MORE

4. 2. Lifetime assessment of complex industrial systems - A framework for renewal strategies

   Author : Mathias Strömberg; KTH; []
   Keywords : Lifetime assessments; residual lifetime; renewal strategies;

   Abstract : For technical systems in the electricity and paper and pulpindustries, asset management is emerging as a new approachaddressing how to exploit physical assets with long operativelives in the most profitably way. An important problem forasset management staff is knowing when to carry out areplacement or renewal. READ MORE

5. 3. Recycling and durability of PVC materials focusing on pre- and post-consumer wastes from building products

   Author : Nazdaneh Yarahmadi; SP – Sveriges Tekniska Forskningsinstitut *(2016-12-31) SP – Sveriges Tekniska Forskningsinstitut; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Accelerated ageing; Activation energy; Annealing; Cables; Dehydrochlorination; Dismantling; DSC; Elongation at break; Emissions; Energy recovery; Flooring; Heat ageing; Lifetime; Orientation; Physical ageing; Plasticised PVC; Plasticiser depletion; Profiles; Recycling; Repeated extrusion; Residual stability; Rigid PVC; Sustainable building; Chlorination; Degradation; Durability; Mechanical properties; Plastic building materials; Plasticizers; Stabilizers agents ; Tensile properties; Molecular level; Polyvinyl chlorides;

   Abstract : The potential for recycling various polymeric materials contained within buildings constructed in the late 1960s and 1970s in Sweden was investigated during the course of this work. Three residential blocks were studied to establish the quantity of materials available for recycling, to investigate the difficulty in and time needed for the dismantling of the buildings, the degree of purity of the materials, and the possibility of separating the materials.

6. 4. Lifetime Measurements of Excited States in the Semi-Magic Nucleus 94Ru

   Author : Aysegul Ertoprak; Bo Cederwall; Magdalena Zielinska; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; nuclear structure; lifetime measurements; doppler shift attenuation method; thick target; Fysik; Physics;

   Abstract : Lifetimes of highly excited states in the semi-magic (N=50) nucleus 94Ru were deduced from an analysis of the Doppler broadened transition line shapes. Excited states in 94Ru were populated in the 58Ni(40Ca, 4p)94Ru∗ fusion-evaporation reaction at the Grand Accélérateur National d’Ions Lourds (GANIL) accelerator complex situated in Caen, France.

7. 5. Maintenance management of complex industrial systems : a methodology for renewal strategies

   Author : Mathias Wärja; Torsten Cegrell; Per Lamell; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; residual lifetime estimation; maintennance management; technical systems in power and pulp- and paper industries; long terms maintenance strategies; Industrial engineering and economy; Industriell teknik och ekonomi;

   Abstract : For complex technical systems in the electricity and pulp and paper industries, maintenance management addresses how to exploit physical assets in the most profitably way. This is a difficult task that requires taking into consideration parameters of totally different natures – e.g. READ MORE
