1. 11. On the use of periodic operation for improvning chemical processes

   Författare :Lennart Vamling; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; periodic operation; di-; ammonia; and triethanolamine production; ethylene oxide; zeolites; Mono-; yield; adiabatic packed-bed reactor; selectivity;

   Sammanfattning : In this thesis, some methods of improving the product distribution from chemical processes are compared. The first two parts contain an experimental investigation of how the product distribution of a process is influenced by the choice of catalyst. LÄS MER

3. 12. Integration of Distributed Renewable Energy and Energy Storages in Buildings

   Författare :Yang Zhang; Jinyue Yan; Pietro Elia Campana; Anders Lundblad; Zhe Chen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building; PV; Energy Storage; Operation; Optimization; Flexibility;

   Sammanfattning : Photovoltaic (PV) is a distributed renewable energy technology that is suitable for integration in buildings. PV reduces the electricity demands as well as the greenhouse gas emissions of buildings. LÄS MER

4. 13. Life Cycle Costing in Road Planning and Management : A Case Study on Collision-free Roads

   Författare :Jonas Wennström; Håkan Sundquist; Tommy Edeskär; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; collision-free road; design; infrastructure; investment; life cycle costing; life cycle cost analysis; maintenance; management; operation; planning; road; sustainability;

   Sammanfattning : Construction of infrastructure does not only mean large capital investments but also future costs to operate and maintain these assets. Decision making in planning and design of roads will impact the need of future operation and maintenance activities. LÄS MER

5. 14. Co-operation in vocational rehabilitation : methods in multiprofessional cross-sector group meetings and effects on employment

   Författare :Björn Jakobsson; Mittuniversitetet; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rehabiliteringsvetenskap; Social medicine; Socialmedicin;

   Sammanfattning : The overall aim of the thesis was to acquire an increased knowledge of co-operation between different rehabilitation actors in the provision of vocational rehabilitation (VR). One aim was to investigate the differences in effects on employment between clients rehabilitated according to a systematic multi-professional cross-sector co-operation model (SMCVR) and clients subjected to conventional co-operation.
