2. 1. Impacts of Thermo-Physical Properties on Chemical Absorption for CO2 Capture

   Author : Worrada Nookuea; Jinyue Yan; Hailong Li; Eva Thorin; Bin Liang; Xiaoyan Ji; Jesus Zambrano; Mälardalens högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

   Abstract : Following the climate change mitigation target in Paris agreement, the global warming has to be limited to 2.0°C above the preindustrial levels. One of the potential methods is carbon capture and storage (CCS), which can significantly reduce the CO2 emissions from the vast point sources such as power plants, industries, and natural gas processes.

4. 2. In-plane tension behaviour of masonry

   Author : Miklos Molnar; Avdelningen för Konstruktionsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; restrained shrinkage; cracking; movement joints; Building construction; mortar joints; KstrMasonry; masonry; in-plane tension; Byggnadsteknik; murverk; sprickor; krympning; dilatationsfogar;

   Abstract : The main purpose of the present work is to increase knowledge of in-plane tension behav-iour of masonry and develop a model able to describe the impact of parameters influencing cracking caused by restrained shrinkage. In the process the mechanism of load transfer between units and mortar joints is described. READ MORE

5. 3. Behaviour of fracture process zones in concrete influenced by simultaneously applied normal and shear displacements

   Author : Manouchehr Hassanzadeh; Avdelningen för Byggnadsmaterial; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; softening; mixed mode; fictitious crack model; concrete; deformationer; betong; brottmekanik; hållfasthet; brotthållfasthet; spänningar; skjuvspänningar; sprickor; beräkningsmodeller; brottenergi; teori; laboratorieförsök; interlock; crack path; diagonal crack; microcracking; instability; fracture energy; fracture mechanics; shear; tension; process zone;

   Abstract : The thesis deals with the determination of the post peak behaviour of concrete in pure tension, and combined tension (compression) and shear. A test arrangement has been developed in order to determine the post peak behaviour of concrete expressed as stress - displacement curves. READ MORE

6. 4. Studies in the Transformation of Post-Soviet Cities : Case Studies from Kazakhstan

   Author : Michael Gentile; Jan Öhman; Örjan Sjöberg; Thomas Lundén; Uppsala universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social and economic geography; Kazakhstan; former Soviet Union; urbanisation; survey method; post-Soviet cities; residential preferences; socio-spatial differentiation; Kulturgeografi; Human geography; Kulturgeografi;

   Abstract : Since the demise of central planning, post-Soviet cities have found themselves operating in a radically different economic climate. Contrary to the situation during the Soviet époque, market relations and the urban economy's adjustment thereto constitute the reality which urbanites face in their daily lives. READ MORE

7. 5. Stabilising system for multi-storey beam and post timber buildings

   Author : Gabriela Tlustochowicz; André J.M. Jorissen; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

   Abstract : For multi-storey timber buildings, the stabilisation against horizontal loads is one of the key issues, which becomes more severe with height. There are a few main concepts utilised to resist lateral forces; shear wall action, diagonal bracing, and frame action. READ MORE
