  3. 2. Folkets fonder? : En textvetenskaplig studie av det svenska pensionssparandets domesticering

    Författare :Claes Ohlsson; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Sweden; pension savings; fund industry; domestication; text analysis; discourse analysis; genre analysis; Swedish; Svenska språket Nordiska språk; pension savings; fund industry; domestication; text analysis; discourse analysis; genre analysis; Swedish;

    Sammanfattning : The social and political background for this study is the change in Sweden from a system of a collective pension scheme to a system that includes elements of individual responsibility and a higher personal involvement of Swedes in pension saving funds. This phenomenon has been conceptualized as domestication, a metaphor that serves as a unifying notion in this study. LÄS MER

  4. 3. Method and technique development in peptide and protein mass Spectrometry

    Författare :Kristina Håkansson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; electrospray ionization; peptide sequencing; Fourier transform ion cyclotron resonance; hydrogen deuterium exchange; protein structure; Materialvetenskap; Materials science; Teknisk materialvetenskap; Molecular Biotechnology; Molekylär bioteknik;

    Sammanfattning : Mechanistic studies and applicability of several methods and techniques for studying peptides and proteins with mass spectrometry are presented. A model for the protein molecular ion formation in explosive matrix-assisted plasma desorption mass spectrometry is proposed, involving a contribution from the chemical energy release during conversion of the explosive, an enhanced protonation through collisions with products from the explosive decay, and electron scavenging by other products.

  5. 4. Fabry-Pérot based refractometry : development of a transportable refractometer for assessment of gas pressure

    Författare :Clayton Forssén; Ove Axner; Isak Silander; Martin Zelan; Leslie Pendrill; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fabry-pérot; refractometry; optical resonator; transportable; pressure standard; gamor; pressure; metrology; ring comparison; si; pascal; quantumpascal; fysik; Physics;

    Sammanfattning : A unified description of physical phenomena through measurement science is one of the foundational pillars in a global society. The International System of Units (SI) is the most widely used system of units and since its redefinition in 2019, all units encompassed by it are based on fundamental physical constants. LÄS MER

  7. 5. Low-Temperature Heating and Ventilation for Sustainability in Energy Efficient Buildings

    Författare :Arefeh Hesaraki; Sture Holmberg; Bahram Moshfegh; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low-temperature heating system; Energy savings; Seasonal thermal energy storage; Variable air volume ventilation system; Indoor air quality;

    Sammanfattning : In 2013, the building sector consumed approximately 39 % of the total final energy use in Sweden. Energy used for heating and hot water was responsible for approximately 60 % of the total energy consumption in the building sector. Therefore, energy-efficient and renewable-based heating and ventilation systems have high potential for energy savings. LÄS MER
