  2. 11. Effects of Lightning Electromagnetic Pulse and High Power Microwaves on Military Electric Systems

    Author : Stefan Silfverskiöld; Michel Ianoz; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; LEMP; HPM; electronic warfare; anechoic chamber; reverberation chamber; Teknisk fysik; Engineering physics; Teknisk fysik; Electricity; Esp The Study Of Transients and Discharges; elektricitetslära; ssk studiet av transienter och urladdning;

    Abstract : The awareness of the threat posed by Lightning Electromagnetic Pulse (LEMP) and High Power Microwaves (HPM) against the operational reliability of electric systems is rapidly growing. This has led to an increasing need for reliable tools, experimental as well as theoretical, for design, analysis and verification of system immunity against electromagnetic threats. READ MORE

  4. 12. Numerical Modelling of Transients in Electrical Systems

    Author : Mihael Zitnik; Marcos Rubinstein; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; Electricity; Esp The Study Of Transients and Discharges; elektricitetslära; ssk studiet av transienter och urladdning;

    Abstract : This thesis deals with the numerical modelling of the response of electrical systems to transient surge voltages and currents caused by lightning. Electrical systems, when subjected to high amplitude transients behave in ways very different from its behaviour under normal operating conditions. READ MORE

  5. 13. Dealing with damaged lysosomes : Impact of lysosomal membrane stability in health and disease

    Author : Ida Eriksson; Karin Öllinger; Petra Wäster; Stig Linder; Daniel Wüstner; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The lysosome is the main unit for degradation and plays important roles in various cellular processes, such as nutrient sensing, cholesterol regulation and cell death. Consequently, altered lysosomal function contributes to, or even causes, several diseases. READ MORE

  6. 14. On a biomechanical approach to analysis of stability and load bearing capacity of oral implants

    Author : Anders Halldin; Malmö högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; animal model; bone resorption; implant stability; cortical bone; viscoelastic-viscoplastic; creep remodeling; constitutive model;

    Abstract : IntroductionWhen an implant is placed in the bone the body responds to thetrauma by encapsulating the implant and its survival depends onthe ability for hard tissue encapsulation. The stability of the implantduring the healing phase is essential to achieve a good result[1]. Biological, physiological and mechanical phenomena affectimplant stability. READ MORE

  7. 15. Adaptation and Constraint in the Plant Reproductive Phase

    Author : Kjell Bolmgren; Ove Eriksson; Bengt Oxelman; Jeff Ollerton; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; phenology; fleshy fruits; phylogenetic comparative methods; phylogenetic constraints; Rhamnus; Frangula; Frangula alnus; key innovations; allometry; diversity; phylogeny; seed size; frugivory; germination; recruitment; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Abstract : Conservatism is a central theme of organismic evolution. Related species share characteristics due to their common ancestry. Some concern have been raised among evolutionary biologists, whether such conservatism is an expression of natural selection or of a constrained ability to adapt. READ MORE
