  2. 11. Moisture Induced Stress Perpendicular to Grain in Timber Structures

    Author : Martin Häglund; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood.; timber; perpendicular to grain; load combination factor; tensile stress; mechano-sorption; Moisture induced eigen-stress; varying moisture content;

    Abstract : Timber structures and wooden element are in general affected by moisture and moisture variation in different ways. Their hygroscopic properties result in adsorption of water when wetted and in desorption when dried. READ MORE

  4. 12. Stress system function in abdominal obesity. The hypothalamic-pituitary-adrenal axis and the sympathetic nervous system in middle-aged men

    Author : Thomas Ljung; Göteborgs universitet; []
    Keywords : Abdominal obesity; stress; HPA axis; cortisol; glucocorticoid receptors; sympathetic nervous system; catecholamines; depression; SSRI;

    Abstract : Background: There is a strong relationship between central (abdominal, visceral) obesity, impaired glucose tolerance, insulin resistance, dyslipidemia and elevated blood pressure. These abnormalities are included in the term Metabolic Syndrome, and indicate an elevated risk for cardiovascular disease and diabetes type 2. READ MORE

  5. 13. Wood-fibre composites : Stress transfer and hygroexpansion

    Author : Karin M. Almgren; Kristofer Gamstedt; Véronique Michaud; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : Wood fibres is a type of natural fibres suitable for composite applications. The abundance of wood in Swedish forests makes wood-fibre composites a new and interesting application for the Swedish pulp and paper industry. READ MORE

  6. 14. Residual Stress Distributions in Additively Manufactured Parts : Effect of Build Orientation

    Author : Prabhat Pant; Ru Lin Peng; Johan Moverare; Kjell Simonsson; Jonathan Almer; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Residual stress; Neutron diffraction; FEM;

    Abstract : Additive manufacturing (AM) of parts using a layer by layer approach has seen a rapid increase in application for production of net shape or near-net shape complex parts, especially in the field of aerospace, automotive, etc. Due to the superiority of manufacturing complex shapes with ease in comparison to the conventional methods, interest in these kinds of processes has increased.

  7. 15. Role of oxidative stress response in radiosensitivity

    Author : Ali Pour Khavari; Siamak Haghdoost; Bo Stenerlöw; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Oxidative stress; radiosensitivity; 8-oxo-dG; DNA-repair; NRF2; glioblastoma; radiotherapy; molekylär biovetenskap; Molecular Bioscience;

    Abstract : The quality of the ionizing radiation (IR) can be described in terms of its nature, photons or particles, and their corresponding energies. The energy is classified in terms of High or Low linear energy transfer that will produce a different distribution of DNA damage and other molecules in the cell either by direct action or indirect action.
