  1. 1. On the fluid mechanics of electrochemical coating and spray painting

    Författare :Pedro Olivas; KTH; []
    Nyckelord :mass transfer; electrochemical coating; ion transport; forced convection; diffusion; magnetoelectrolysis; electrolyte; limiting current; numerical simulation;

    Sammanfattning : Finite-volume methods have been used for modeling of fluidflows involved in forced convection electrochemical coating androtating spray painting systems. Electrodeposition on a singlecircular cylinder under forced convection for Reynolds numbers10 and 200 was simulated. LÄS MER

  3. 2. Chloride transport and chloride thresholdvalues-Studies on concretes and mortars with Portland cement and limestone blended cement

    Författare :Dimitrios Boubitsas; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete; cement; limestone filler; chloride ingress; chloride threshold values;

    Sammanfattning : Reinforced concrete is one of the most widely used building materials and if it is properly designed and produced, it is an extremely durable material with a service life up to 100 years. However, under certain environmental conditions the service life of reinforced concrete structures is more limited. LÄS MER

  4. 3. Limiting conditions for a sustained flame over condensed fuels : Analysis by experiments and stagnant layer theory

    Författare :Frida Vermina Plathner; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Critical mass flux; diffusion flame; extinction; sustained ignition; chemical heat of combustion; Convective heat transfer coefficient; external heat flux;

    Sammanfattning : Ignition and extinction characteristics of a material determine whether a fire will be initiated and grow. In fire safety engineering, where modellers deal with a multitude of materials, simplified thresholds are commonly used to determine when ignition and extinction occur. LÄS MER

  5. 4. Om rekrytering i akademin - exemplen prefekter och forskarstuderande

    Författare :Thomas Sandstedt; Leif Lindberg; Mats Benner; Anders Fransson; Linnéuniversitetet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; academic leadership; academic freedom; collegiality; criteria; department head; fitting in; forms; norms and values New Institutional Theory ; legitimacy; process; recruitment; regulatory system; research student; rules of the game and silent knowledge.; Pedagogics and Educational Sciences; Pedagogik och Utbildningsvetenskap;

    Sammanfattning : Sandstedt, Thomas (2013) – On Recruitment in Academia in the Cases of Department Heads and Research Students  This thesis study how academic and scientific culture act and handle the balance between different interests, demands and preferences and what is considered central and valuable in the leading and managing within universities in Sweden. These are set against each other whenever department heads and research students are to be recruited. LÄS MER

  7. 5. Galanin : a modulator of serotonin neurotransmission : relevance for depression

    Författare :Haleh Razani; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :galanin; 5-HT1A receptors; 5-HT; 8-OH-DPAT; fluoxetine; robalzotan; passive avoidance; microdialysis; mRNA; KD values; Bmax values; depression;

    Sammanfattning : Galanin is widely distributed throughout the central nervous system with multiple and diverse biological roles. In the rat, galanin-like immunoreactivity is expressed in a population of5-hydroxytryptamine (5-HT, serotonin) neurons in the dorsal raphe (DR) with extensive projections to the forebrain areas e.g., hippocampus.
