1. 1. On Sahelian-Sudan rainfall and its moisture sources

   Författare :Abubakr A. M. Salih; Qiong Zhang; Michael Tjernström; Alessandra Giannini; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sudan; Sahel; rainfall; land use; deforestation; moisture sources; moisture transport; Lagrangian; moisture tagging; regional model; climate modeling; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

   Sammanfattning : The African Sahel is one of the most vulnerable regions to climate variability at different time scales. It is an arid to semi-arid region with limited water resources. The summer rainfall is one of these sources, but it exhibits pronounced interannual variability. This thesis presents several aspects of Sahelian Sudan rainfall. LÄS MER

3. 2. Investigations on moisture damage-related behaviour of bituminous materials

   Författare :Umaru Bagampadde; Ulf Isacsson; Manfred Partl; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Moisture damage; State-of-the-Art; Stripping; Moisture sensitivity; Bituminous materials; Construction engineering; Konstruktionsteknik;

   Sammanfattning : This doctoral thesis presents results of literature review on classical and contemporary aspects of stripping, as well as experimental investigations on moisture damage as influenced by bituminous materials. Previous research in the area of moisture damage was reviewed and synthesized into a state-of-the-art. LÄS MER

4. 3. Field Measurements for Verification of the Impact of Renovation and Maintenance Measures on Buildings : - regarding Energy Efficiency, Indoor Environment and Moisture Safety

   Sammanfattning : Chemical compounds in indoor air can adversely affect our comfort and health. However, in most cases there is only a limited amount of information available that can be used to assess their health risk. Instead the precautionary principle is often applied, i.e. LÄS MER

7. 5. Putsens inverkan på fasadens fuktbalans

   Författare :Kenneth Sandin; Avdelningen för Byggnadsmaterial; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rendering; moisture; driving rain; absorption; drying; provningsmetoder; mätmetoder; kondens; slagregn; fukt; ytterväggar; puts; fasader; pore structure; surface coating; diffusion;

   Sammanfattning : The report deals with the effect of renderings on the moisture balance in facades. The main therne is the moisture mechanism in cnnnection with different moisture sources. Different opinions about moisture in facades and consequences of moisture are mentioned as a background. LÄS MER
