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

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Ted Sjöberg; Luleå tekniska universitet.; [2014]
    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

  4. 2. Electronic Structure and Lattice Dynamics of Elements and Compounds

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Petros Souvatzis; Uppsala universitet.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atomic and molecular physics; electronic structure; lattice dynamics; first-principles theory; self-consistent lattice dynamical calculation; elasticity; super plasticity; electronic topological transition; equation of state; Atom- och molekylfysik;

    Abstract : The elastic constants of Mg(1-x)AlxB2 have been calculated in the regime 0<x<0.25. The calculations show that the ratio, B/G, between the bulk- and the shear-modulus stays well below the empirical ductility limit, 1. READ MORE

  5. 3. Striatal adaptations in experimental parkinsonism and L-DOPA-induced dyskinesia

    University dissertation from Neurobiology, Lund University, Faculty of Medicine

    Author : Tim Fieblinger; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2014]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Striatum; Parkinson’s disease; L-DOPA-induced dyskinesia; ERK1 2; mGluR5; homeostatic plasticity; SPN; 2‑Photon microscopy;

    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

    University dissertation from Stockholm : Karolinska Institutet, Dept of Women's and Children's Health

    Author : Linda Westin; Karolinska Institutet.; Karolinska Institutet.; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    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

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Stefan Marth; Luleå tekniska universitet.; [2017]
    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.
