  2. 1. Plasticity modelling of nickel based super alloy Alloy 718

    Author : Ted Sjöberg; Paul Åkerström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : The ever growing demand on reduced fuel consumption in modern aircrafts puts high requirements on manufacturers to reduce weight in all parts of the aircraft. With a total weight of up to one fifth of an aircraft’s total operating weight, ways to decrease the weight of the engine systems are continuously sought. READ MORE

    Abstract : Parkinson’s disease (PD) is a neurodegenerative disorder, characterized by the loss of dopamine (DA) producing neurons in the substantia nigra pars compacta (SNc), resulting in typical motor symptoms. DA replacement with L-DOPA is the standard therapy for PD. READ MORE

  6. 4. Studies on the plasticity of glutamate receptors and its role for neuronal calcium homeostasis

    Author : Linda Westin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Calcium is the most important and versatile signaling molecule in the brain. Neurons are equipped with a variety of tools to utilize this simple ion in diverse ways. From controlling the millisecond fast neurotransmitter release, to reshaping neuronal structure and function. READ MORE

  7. 5. Material Characterization for Modelling of Sheet Metal Deformation and Failure

    Author : Stefan Marth; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : Weight reduction is one possibility to reduce fuel consumption and emission of transportation vehicles. Sheet metals are often used in automotive and aerospace applications and therefore the weight reduction achieved by reducing the sheet metals thickness is an important contribution to weight reduction.
