2. 1. Impact of moisture on long term performance of insulating products based on stone wool

   Author : Tomás Vrána; Folke Björk; Per Ingvar Sandberg; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineral insulation; Stone wool; Material properties; Moisture transport; Heat transport; Test equipment; Moisture properties; Frost formation; Building engineering; Byggnadsteknik;

   Abstract : Demands for energy have been increasing in the whole world. According to higher consumption, the price of energy rises yearly too. This evokes usage of insulating products in a wider range. READ MORE

4. 2. Mineral fibers, cigarette smoke, and oxidative DNA damage : An experimental study

   Author : Per Leandersson; Östergötlands Läns Landsting; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : This study concerns the ability of mineral fibers and cigarette smoke to generate reactive oxygen metabolites and to cause damage to DNA. The generation of hydroxyl radicals (OH") was demonstrated by using the DNA base, deoxyguanosine (dG) as a trapping agent for OH" and determining its hydroxylation to 8-hydroxydeoxyguanosine (80HdG), and oxidative DNA damage was assessed as formation of 80HdG in isolated DNA or in DNA of human lung cells in culture.

5. 3. Sensory evaluation and consumer preference of wine and food combinations : influences of tasting techniques

   Author : Ingemar Tobias Nygren; Inga-Britt Gustafsson; Lisbeth Johansson; Åsa Öström; Hely Tuorila; Örebro universitet; []
   Keywords : Descriptive sensory analysis; tasting technique; sequential tasting; mixed tasting; wine; combination; Hollandaise sauce; blue mold cheese; consumers; preference; måltidskunskap; Culinary Arts and Meal Science; Måltidskunskap; Måltidskunskap; Culinary Arts and Meal Science;

   Abstract : The entire project consists of five studies. Descriptive sensory analyses were performed on combinations of five dry white wines and either Hollandaise sauce with two levels of fat or two blue mould cheeses. Assessments were carried out by a student panel and by a selected and trained panel. READ MORE

6. 4. Application of the Boundary Element Method to combustion noise and half-space problems

   Author : Haike Brick; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; impedance plane; Green s function; horn effect; Kirchhoff s surface; Hybrid approach; tyre-road interface;

   Abstract : The Boundary-Element-Method (BEM) is a powerful and established tool in computational acoustics. This thesis aims at an enhancement of the method towards combustion noise and half-space problems.First, it is directly coupled to an incompressible Large Eddy Simulation (LES) to calculate the sound radiation of open flames.

7. 5. Promotion of sustainable renovation in the built environment : An early stage techno-economic approach

   Author : Navid Gohardani; Folke Björk; Bo-Göran Hellers; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Refurbishment; retrofitting; renovation; energy consumption; Vacuum Insulation Panels; ACES;

   Abstract : According to the Swedish Government's set targets for energy use and environmental quality imposed by the European Union, the total energy per heated unit area in residential and commercial buildings will have to be decreased by 20% in 2020 and 50% by 2050 in relation to the annual consumption of 1995. The building sector should additionally be completely independent of fossil fuels for energy usage, with the increasing sector of renewable energy continuously growing until 2020. READ MORE
