1. 16. Heat shock proteins as vaccine adjuvants

   Författare :Khaleda Rahman Qazi; Carmen Fernández; Qijun Chen; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heat shock protein; vaccine; adjuvant; BCG; Immunology; Immunologi;

   Sammanfattning : New efficient vaccines against infectious diseases are in demand. Some important factors impeding the vaccine development are the poor immunogenicity and the MHC restriction of the immune responses to a number of antigens. LÄS MER

3. 17. Solar Colletors Combined with Ground-Source Heat Pumps in Dwellings - Analyses of System Performance

   Författare :Elisabeth Kjellsson; Avdelningen för Byggnadsfysik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heating in dwellings; TRNSYS simulations; solar collectors; ground-source heat pumps; ground heat;

   Sammanfattning : The use of ground-source heat pumps for heating buildings and domestic hot water in dwellings is increasing rapidly in Sweden. The heat pump extracts heat from the ground by a U-pipe in a vertical borehole. In order to reduce the electricity demand in the system, the combination with solar collectors is introduced. LÄS MER

4. 18. Integrating Latent Heat Storage into Residential Heating Systems : A study from material and component characterization to system analysis

   Författare :Tianhao Xu; Samer Sawalha; Björn Palm; Justin NingWei Chiu; Tianshu GE; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase change material; thermal energy storage; heat pump; load shifting; space heating; Energy Technology; Energiteknik;

   Sammanfattning : Latent heat thermal energy storage (LHTES) systems can be coupled with heat pump (HP) systems to realize heat load shifting on demand side. With phase change material (PCM), well designed LHTES components exhibit high storage energy density and thus have large potentials to be integrated in residence where a compact energy storage solution is needed.

5. 19. Numerical Analysis of Heat Transfer and Fluid Flow in Heat Exchangers with Emphasis on Pin Fin Technology

   Författare :Hamid Nabati; Jafar Mahmoudi; Dan Loyd; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; Heat exchanger; Pin fin technology; Cooling system; Power transformers; CO2; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : One of the most important industrial processes is heat transfer, carried out by heat exchangers in single and multiphase flow applications. Despite the existence of well-developed theoretical models for different heat transfer mechanisms, the expanding need for industrial applications requiring the design and optimization of heat exchangers, has created a solid demand for experimental work and effort.

7. 20. Numerical predictions of heat-transfer applied to electrical machines

   Författare :Kristian Rönnberg; Christophe Duwig; Anders Dahlkild; Luca Peretti; Jens Honore Walther; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric machines; energy efficiency; heat transfer; thermal management; high fidelity simulation; computational fluid dynamics CFD ; proper orthogonal decomposition POD ; lumped parameter thermal network LPTN ; Elektriska maskiner; energieffektivitet; verkningsgrad; värmeöverföring; värmehantering; simuleringar med hög upplösning; strömningsmekaniska beräkningar; proper orthogonal decomposition POD ; termiska nätverk; Teknisk mekanik; Engineering Mechanics;

   Sammanfattning : In order to meet the need for increased electrification, and at the same time reduce the total demand for electric energy, behavior change and technological innovation is needed. Over the decades power density of electric motors have increased, leading to increased demands on the cooling system design and performance. LÄS MER
