1. 1. Mathematics teaching through the lens of planning : actors, structures, and power

   Författare :Helena Grundén; Jeppe Skott; Sara Irisdotter Aldenmyr; Anna Chronaki; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mathematics education; mathematics teaching; planning; Critical Discourse Analysis; actors; structures; power; Mathematical Education; Matematikdidaktik;

   Sammanfattning : This dissertation explores mathematics teaching by focusing on planning. The planning is seen as a social phenomenon related to surrounding practices and power relations in and between practices. Hence, planning in this dissertation is explored beyond what teachers do when planning. LÄS MER

3. 2. Structures, toxicity and internalization of cell-penetrating peptides

   Författare :Emelía Eiríksdóttir; Ülo Langel; Michael Gait; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CPP; cell-penetrating peptide; internalization; toxicity; structures; Neurochemistry; Neurokemi; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

   Sammanfattning : Cellular internalization is a highly regulated process controlled by proteins in the plasma membrane. Large and hydrophilic compounds, in particular, face difficulties conquering the plasma membrane barrier in order to gain access to intracellular environment. This puts serious constrains on the drug industry since many drugs are hydrophilic. LÄS MER

4. 3. Modular long-span timber structures : a systematic framework for buildable construction

   Författare :Anders Björnfot; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

   Sammanfattning : One of the identified reasons for the low amount of timber construction in Sweden is a general lack of knowledge about timber engineering and how timber can be used to its full advantage. One way for increased timber construction is the development of a cost-efficient and easy to comprehend building system. LÄS MER

5. 4. Reinforcement in Tailor-made Concrete Structures

   Författare :David Fall; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tailor-made concrete structures; Steel fibre reinforcement; Automated production; Geometrically complex structures; Reinforcement alternatives;

   Sammanfattning : In tailor-made concrete structures of complex geometries, the formability of concrete is an asset. To use this formability in load-bearing structures, the concrete needs to be reinforced. During the past century steel bars were used; however, in recent decades, alternative reinforcement methods have been introduced. LÄS MER

7. 5. Multiphase models for freeze-thaw actions and mass transport in concrete hydraulic structures

   Författare :Daniel Eriksson; Anders Ansell; Richard Malm; Erik Nordström; Stefan Jacobsen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Degradation; Hydraulic structures; Air-entrained concrete; Multiphase models; Multiphysics; Long-term moisture conditions; Freeze-thaw; Hysteresis; Absorption; Calcium leaching; Finite Element Method; Concrete Structures; Betongbyggnad;

   Sammanfattning : A crucial task for civil engineers is to make appropriate designs of new concrete structures and assessments of existing structures to ensure a long service life and sustainable use of the infrastructure. This doctoral thesis aims to increase the understanding of how advanced mathematical models can be used to describe phenomena and processes governing concrete degradation and thereby ultimately contribute to improving tools for design and assessments.
