  2. 1. Transthyretin and the transthyretin-related protein: A structural study

    Author : Erik Lundberg; A. Elisabeth Sauer-Eriksson; Lennart Sjölin; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Transthyretin; Transthyretin-related protein; X-ray crystallography; Protein structure; Amyloidosis; Structural biology; Strukturbiologi;

    Abstract : Transthyretin (TTR) is one of several proteins involved in amyloid disease in humans. Unknown conformational changes of the native state of TTR result in aggregation of TTR molecules into amyloid fibrils, which accumulate in extracellular tissues. This may result in different clinical symptoms, e.g. READ MORE

  4. 2. Impact of Metallic Projectiles on a Ceramic Target Surface : Transition Between Interface Defeat and Penetration

    Author : René Renström; Bengt Lundberg; Patrik Lundberg; Nils-Gunnar Ohlson; Uppsala universitet; []
    Keywords : Engineering physics; Projectile; Cylindrical; Conical; Yield strength; Compressibility; Perfect flow; Self-similar flow; Interface defeat; Dwell; Teknisk fysik; Teknisk fysik med inriktning mot hållfasthetslära; Engineering Science with specialization in Solid Mechanics;

    Abstract : The purpose of this thesis is to gain understanding of the load on flat target surfaces produced by projectile impact. Models are proposed from which upper and lower bounds can be derived for the transition be-tween interface defeat and normal penetration. READ MORE

  5. 3. Interface Defeat and Penetration: Two Modes of Interaction between Metallic Projectiles and Ceramic Targets

    Author : Patrik Lundberg; Bengt Lundberg; Charles E. Anderson Jr.; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; projectile; target; impact; interface defeat; penetration; tungsten; ceramic; replica scaling; Teknisk fysik; Engineering physics; Teknisk fysik;

    Abstract : Ceramics constitute an important group of low-density armour materials. Their high intrinsic strength makes it possible to design ceramic armour systems capable of defeating projectiles directly on the ceramic surface. READ MORE

  6. 4. On methods for estimating oceanic flow

    Author : Jenny A. U. Nilsson; Peter Lundberg; Peter Sigray; Bert Rudels; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ocean monitoring techniques; Barotropic flow; Baroclinic flow; Hydraulic theory; Baltic Sea; Bahía de Concepción; Oceanography; Oceanografi; Oceanography; oceanografi;

    Abstract : The aim of this thesis was to estimate and possibly quantify ocean flow by utilizing conventional and novel observational methods as well as model results. Motionally induced voltages, from a cable-based observational system in the Baltic Sea, were analysed to determine their utility for ocean monitoring. READ MORE

  7. 5. Ridged sea ice modelling in climate applications

    Author : Sebastian Mårtensson; Markus Meier; Kristofer Döös; Peter A. Lundberg; Frank Kauker; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arctic ocean; Baltic Sea; sea ice; ice dynamics; numerical modelling; climate; ice deformation; ice compression; physical and biogeochemical interactions; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : This work aims to increase our understanding of the nature of large scale features of sea ice from a dynamics point of view.Sea ice plays an important part in the exchange of heat and humidity between sea and air and thus is an important component of the climate system. READ MORE
