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

   Author : Abubakr A. M. Salih; Qiong Zhang; Michael Tjernström; Alessandra Giannini; Stockholms universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

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

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

   Abstract : 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. READ MORE

5. 3. Characteristics of wood plastic composites based on modified wood : Moisture properties, biological performance and micromorphology

   Author : Kristoffer Segerholm; Magnus Wålinder; Mark Hughes; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood plastic composites; WPC; acetylation; thermal modification; furfurylation; moisture sorption; biological durability; UV excimer laser; micromorphology;

   Abstract : Biobased materials made from renewable resources, such as wood, play an important role in the sustainable development of society. One main challenge of biobased building materials is their inherent moisture sensitivity, a major cause for fungal decay, mold growth and dimensional instability, resulting in decreased service life as well as costly maintenance.

6. 4. Moisture Influence on Structural Behaviour of Pavements : Field and Laboratory Investigations

   Author : Farhad Salour; Sigurdur Erlingsson; Guy Doré; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Falling Weight Deflectometer FWD ; backcalculation; unbound material; subgrade; seasonal variation; moisture content; spring-thaw; drainage; pavement stiffness; field test; pavement instrumentation; resilient modulus; permanent deformation; repeated load triaxial test; unsaturated soil; matric suction.; Civil and Architectural Engineering; Byggvetenskap; Transportvetenskap; Transport Science;

   Abstract : The structural behaviour of pavements in cold regions can considerably be affected by seasonal variation in environmental factors such as temperature and moisture content. Along with the destructive effect of heavy traffic loads, climatic and environmental factors can considerably contribute to pavement deterioration. READ MORE

7. 5. Characterising the Deformation Behaviour of Unbound Granular Materials in Pavement Structures

   Author : Mohammad Shafiqur Rahman; Sigurdur Erlingsson; Charles Schwartz; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; unbound granular materials; resilient modulus; permanent deformation; moisture; model; multistage; repeated-load triaxial test; Transportvetenskap; Transport Science; Civil and Architectural Engineering; Byggvetenskap;

   Abstract : Unbound granular materials (UGMs) used in the base and sub-base layers of flexible pavements play a significant role in the overall performance of the structure. Proper understanding and characterization of the deformation behaviour of UGMs in pavement structures are, therefore, vital for the design and maintenance of flexible pavements. READ MORE
