1. 1. Sustainability and Flexural Behaviour of Textile Reinforced Concrete

   Författare :Natalie Williams Portal; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Life Cycle Assessment LCA ; sustainability; Textile Reinforced Concrete; TRC; facade elements; flexural behaviour; non-linear finite element analyses; structural tests;

   Sammanfattning : Concrete reinforced with conventional steel is one of the most commonly used building materials, yet it has historically shown disadvantages in terms of durability and vulnerability to corrosion attack. Various remedial methods have been applied to overcome the shortcomings of this building material, such as increasing the concrete cover, which, however, leads to an increased self-weight of the structure.

3. 2. Usability of Textile Reinforced Concrete: Structural Performance, Durability and Sustainability

   Författare :Natalie Williams Portal; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sustainability; life cycle assessment; experimental methods; finite element analysis; durability; Textile reinforced concrete;

   Sammanfattning : Textile reinforced concrete (TRC) is an innovative high performance composite material consisting of open multi-axial textiles embedded in a fine-grained concrete matrix. Despite the fact that TRC-based research has revealed many promising attributes, it has yet to reach its recognition due to a lack of available design tools, standards and long-term behaviour.

4. 3. Att räkna med alla elever : följa och främja matematiklärande i förskoleklass

   Författare :Helena Vennberg; Maria Berge; Gunnar Sjöberg; Anna Ida Säfström; Jorryt van Bommel; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Preschool-class; mathematics; assessment; intervention; at-risk-student; special educational needs; Förskoleklass; matematik; specialpedagogik; lärande; bedömning; i-risk-elev; intervention; SUM; pedagogiskt arbete; educational work;

   Sammanfattning : Förskoleklassen har en speciell position mellan två skilda kulturer där utveckling och lärande har olika betydelse. Avhandlingens syfte är att bidra med kunskap om förskoleklasslärares möjligheter att följa och främja alla elevers utveckling och lärande i matematik. Avhandlingen består av fyra studier. LÄS MER

5. 4. Waste Heat Recovery in Heavy Duty Diesel Engines

   Författare :Jelmer Johannes Rijpkema; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Organic Flash Cycle; Heavy Duty Diesel Engine; Organic Rankine Cycle; Trilateral Flash Cycle; Transcritical Rankine Cycle; Internal Combustion Engines; Waste Heat Recovery;

   Sammanfattning : Over 50% of the energy released by burning fuel in a truck engine is lost as heat rather than being used to propel the vehicle. A promising method for capturing and reusing this heat, and thereby improving engine efficiency, is to exploit thermodynamic cycles for waste heat recovery (WHR). LÄS MER

7. 5. Proteome wide protein production

   Författare :Hanna Tegel; Sophia Hober; Diethard Mattanovich; KTH; []
   Nyckelord :protein production; Escherichia coli; transcription; promoter; translation; rare codon; high-throughput; screening;

   Sammanfattning : Over a decade after the completion of the human genome, researchers around the world are still wondering what information is hidden in the genome. Although the sequences of all human genes are known, it is still almost impossible to determine much more than the primary protein structure from the coding sequence of a gene. LÄS MER
