  1. 1. Influence of carbides and nitrides on corrosion initiation of advanced alloys : A local probing study

    Författare :Eleonora Bettini; Jinshan Pan; Thomas Ladwein; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbides; nitrides; microstructure; CoCrMo alloys; duplex stainless steels; localized corrosion; transpassive dissoluti on; elemental depletion; AFM; TEM; SEM.;

    Sammanfattning : Advanced alloys often present precipitated carbides and nitrides in their microstructure following exposure to elevated temperatures. These secondary phases are usually undesirable, because potentially deleterious for the corrosion and mechanical performances of the material. LÄS MER

  3. 2. Corrosion Behavior of Duplex Stainless Steels in Acidic-Chloride Solutions Studied with Micrometer Resolution

    Författare :Marc Femenia; KTH; []
    Nyckelord :In situ; local dissolution; STM; SKPFM; MFM; SAES; duplex stainless steel; acidic-chloride solution;

    Sammanfattning : The local corrosion behavior of duplex stainless steel (DSS)is affected by a wide variety of factors. Localized corrosionof DSS frequently starts at micrometer scale inclusions orprecipitates, which are often segregated in theaustenite-ferrite boundary regions. LÄS MER

  5. 4. Musikhus i centrum : två lokala praktiker inom den svenska progressiva musikrörelsen : Uppsala Musikforum och Sprängkullen i Göteborg

    Författare :David Thyrén; Johan Fornäs; Jacob Derkert; Ola Stockfelt; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; progressive; local practices; communities; scenes; movements; public spheres; subcultures; gender; popular culture; cultural studies; Sweden; Music; Musikvetenskap; Musicology; musikvetenskap;

    Sammanfattning : The dissertation studies local practices within the Swedish progressive or alternative music movement in the 1970s. It analyses how cultural communities were formed on the basis of local musical practices, focusing on two case studies: Musikforum in Uppsala and Sprängkullen in Gothenburg. LÄS MER

  7. 5. Characterisation of an in vitro dissolution method for assessment of novel pulmonary drug delivery systems : With a focus on controlled release systems

    Författare :Irès van der Zwaan; Göran Frenning; Per Hansson; Rebecca Fransson; Alessandra Rossi; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pulmonary drug delivery; in vitro dissolution; mechanistic model; controlled release; physiologically based biopharmaceutics modelling;

    Sammanfattning : Pulmonary drug delivery has been used for decades to treat local diseases like asthma. When using the pulmonary route to deliver drugs, several important lung features are being used, such as a large surface area available for absorption, high organ vascularization, and a thin blood-alveolar barrier.
