2. 1. Critical Moisture Conditions for Mould Growth on Building Materials

   Author : Pernilla Johansson; Avdelningen för Byggnadsfysik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mould; critical moisture level; building material; relative humidity; mould resistance; crawl space; attic;

   Abstract : Materials that are stored or used in damp climates may be subject to mould growth. However, all materials are not equally susceptible to mould growth. For each specific material, there is a critical moisture level. If this is exceeded, there is a risk that mould fungi will develop on the material. READ MORE

4. 2. Determination of the Critical Moisture Level for Mould Growth on Building Materials

   Author : Pernilla Johansson; Avdelningen för Byggnadsfysik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Crawl space; Fungus; Mould resistance; Wood; Building materials; Mould; Critical moisture level; Attic; Relative humidity; Cyclic conditions; Laboratory method;

   Abstract : The susceptibility to mould growth varies between building materials. The factors that most affect mould growth, the relative humidity (RH) and temperature also vary in different parts of buildings. One way of preventing the growth of mould in buildings is therefore to choose building materials that can withstand the expected conditions. READ MORE

5. 3. Heat transfer phenomena and mould flux lubrication in continuous casting of steel

   Author : Akira Yamauchi; KTH; []
   Keywords : Heat Transfer; Thermal Conductivity; Contact Resistance; Mould Flux; Solidification; Lubrication; Infiltration; Friction; Shear Stress; Modeling; Crystallization; Rupture Strength; Solidus; High-Speed Casting; Viscosity; Elasticity; Uniform Cooling;

   Abstract : Overall thermal resistance of the mould flux was measured tomake clear the influence of the mould flux properties on theheat transfer behavior in continuous casting, especiallythermal conductivity and the formation of air gaps in thisstudy. From the investigation of the effect of the mouldsurface temperature and physical properties of the mould fluxon heat transfer through the flux film, following knowledge hasbeen obtained. READ MORE

6. 4. Mould on building materials - A calorimetric study of fungal activity as a function of environmental factors

   Author : Yujing Li; Avdelningen för Byggnadsmaterial; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; materiallära; byggnadsteknik; building construction; fungal activity; temperature; relative humidity; building; image analysis; indoor environment; wood; materialteknik; material technology; mould; calorimetry; isothermal calorimeter;

   Abstract : Mould problems in buildings have become a growing concern during the past decades. The growth of mould fungi indoors deteriorates air quality, influences human health and causes economical losses. Preventing mould growth from occurring is a more cost effective option than cleaning and renovation of buildings with mould problems. READ MORE

7. 5. The Metallurgical Aspects of Machinability in Prehardened Mould Steels

   Author : Seyyed Mohammad Hamed Hoseiny; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bainitic structure; Tool Life; Cutting Temperature; Cutting Force; Machinability; Microstructure; Tempered Martensite; Plastic Mould Steels;

   Abstract : High economical efficiency obtained by utilizing prehardened mould steels in plastic mould making has increased the usage of these types of steels to a great extent. Generally, prehardened mould steels are applied for large moulds and moulds for moderate production runs, and one of the advantages of using this type of steel is that no heat treatment is necessary for putting the mould in use.
