  1. 51. Deformation and Fatigue Behaviour of Aluminium Alloys for High Specific Power IC Engine Applications

    Author : Elanghovan Natesan; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cylinder head; aluminium; constitutive models; thermo-mechanical fatigue; fatigue; ageing; mechanical behaviour; A356;

    Abstract : The development towards higher specific power and lower displacement engines in recent years has placed increasingly high thermal loads on the internal combustion engine materials. Further, the advent of hybrid power trains placing higher demands on quick starts and a rapid approach to maximum power necessitates the automotive industry to move towards a more robust computational thermo-mechanical fatigue life prediction methodology to develop reliable engines and reduce developmental costs.

  2. 52. Cellulose-based Conducting 3D and 2D Composites for Applications in Plant Science and Responsive Systems

    Author : Vasileios Oikonomou; Eleni Stavrinidou; Magnus Berggren; Anna Herland; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polymers; cellulose; conjugated polymers; volume changes; plant growth substrates;

    Abstract : Polymers (Greek: poly=many, meros=part) are large molecules made up of many small parts (monomers) in a repetitive way, as a term was introduced for the first time (1833) by the Swedish chemist, Jöns Jakob Berzelius. By the combination of different monomers, the resulting polymer can exhibit various properties, such as biodegradability, photosensitivity and electrical conductivity. READ MORE

  3. 53. Exploring gene expression responses of marine bacteria to environmental factors

    Author : Christofer Osbeck; Jarone Pinhassi; Michael Cunliffe; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; dissolved organic matter; model bacteria; ocean acidification; organic pollutants; river loadings; transcriptomics; Mikrobiologi; Microbiology;

    Abstract : Bacterioplankton are abundant in marine ecosystems, where they as “masters of transformation” of dissolved organic matter (DOM) are important for energy fluxes and biogeochemical cycles. However, the performance of bacteria in a changing marine environment influenced by anthropogenic activities is poorly understood. READ MORE

  4. 54. Diffusion tests for assessing leaching from incineration residues

    Author : Jelena Todorovic; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

    Abstract : Increasing amounts of incineration residues need to be disposed, reused or treated, which calls for reliable characterisation methods. Leaching tests are often used for an assessment of release of pollutants from wastes under a variety of leaching factors. READ MORE

  5. 55. The Greenhouse - Icehouse Transition : a dinoflagellate perspective

    Author : Caroline A. van Mourik; Henk Brinkhuis; Malgorzata Moczydlowska-Vidal; Stockholms universitet; []
    Keywords : Eocene - Oligocene; dinoflagellate cysts; biostratigraphy; paleoecology; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Through the analysis of the stratigraphic and spatial distribution of organic walled dinoflagellate cysts (dinocysts) from climatologically and oceanographically key sites, this project aims to contribute to a better understanding of the Eocene-Oligocene (E/O) environmental changes and their timing. A central issue is to identify the global environmental changes which are responsible for the Eocene cooling and its underlying mechanisms with the focus on the Oligocene isotope-1 (Oi-1) event, thought to mark the onset of major Antarctic glaciation.
