4. 2. Biological growth on rendered façades

   Author : Sanne Johansson; Avdelningen för Byggnadsmaterial; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; temperature; render; radiation; photosynthesis; moulds; mosses; mortar; moisture; lichens; Imaging-PAM; humidity; heat capacity; heat; ETICS; algae; biological growth; calorimetry; desiccation tolerance;

   Abstract : Biological organisms have an incredible ability to adapt to almost any environment and the humans activities on earth have created many new habitats for different kinds of organisms. For example can certain organisms grow on rocks and vertical cliffs, and when humans started building houses with mineral based façades, some organisms found that these were new habitats to live on.

5. 3. Investigation of Thermal Performance of Cylindrical Heatpipes Operated with Nanofluids

   Author : Morteza Ghanbarpourgeravi; Rahmatollah Khodabandeh; Björn Palm; Oronzio Manca; KTH; []
   Keywords : Nanofluid; heat pipe; thermal resistance; heat transfer coefficient; evaporator; condenser; wick; porous layer; heat flux; inclination angle; thermal conductivity; viscosity; Energiteknik; Energy Technology;

   Abstract : Nanofluids as an innovative class of heat transfer fluids created by dispersing nanometre-sizedmetallic or non-metallic particles in conventional heat transfer fluids displayed the potential toimprove the thermophysical properties of the heat transfer fluids. The main purpose of this study is toinvestigate the influence of the use of nanofluids on two-phase heat transfer, particularly on thethermal performance of the heat pipes. READ MORE

6. 4. Influence of heat on the physical and mechanical properties of selected rock types

   Author : Christine Saiang; Karl-Johan Loorents; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tunnel fires; heat influences; temperature increase; mechanical properties; physical properties; micro cracks; mineralogy; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

   Abstract : Impelled by the increase in the number of tunnel fires in the last decade alone, wide spread attention has been drawn towards tunnel fire safety studies. Many of these fires occurred in road and railway tunnels involving vehicles and trains. READ MORE
