  2. 1. Electrochemical machining: towards 3D simulation and application on SS316

    Author : A. A. Gomez-Gallegos; UK University of Edinburgh; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrochemical machining; 3D Simulation; FEM; stainless Steel 316; surface Finish; Maskinteknik; Mechanical Engineering;

    Abstract : Electrochemical machining (ECM) is a non-conventional manufacturing process, which uses electrochemical dissolution to shape any conductive metal regardless of its mechanical properties and without leaving behind residual stresses or tool wear. Therefore, ECM can be an alternative for machining difficult-to-cut materials, complex geometries, and materials with improved characteristics, such as strength, heat-resistance or corrosion-resistance.

  4. 2. Tipping the scales in cancer : novel mechanisms of inhibiting protein degradation

    Author : Tatiana A Giovannucci; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Protein homeostasis (in short, ‘proteostasis’) requires the timely degradation of proteins to retain control on protein quality, amount and function. Two main proteolytic systems, the ubiquitin-proteasome system (UPS) and autophagy, complement each other to fulfill this regulatory role. READ MORE

  7. 5. Relativistic effects in Compton scattering of photons from bound electron states

    Author : A. Roland Ribberfors; Linköpings universitet; []
    Keywords : ;

    Abstract : What is light? A correct answer to this question is: I don't know, but I can see some of its properties"! It is exciting to study such a complex thing and to search for models which can help us to try to understand, in a proper way, some of the most interesting behavior of light. We see the sunshine and the radiation makes us warm, undoubtly it must be some kind of energy? Interference experiments with monochromatic light show that the radiation has wave-like properties, but for example scattering experiments predict a particle nature. READ MORE
