  1. 1. Figuring Worlds; Imagining Paths : A Feminist Exploration of Identities in Higher Education Biology

    Författare :Katerina Pia Günter; Annica Gullberg; Ingrid Ahnesjö; Karin S. Lindelöf; Maria Berge; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Biology Education; Communities of Practice; Discourse Analysis; Feminist Science Studies; Figured Worlds; Gender; Higher Education; Science Education; Science Identity; Genusvetenskap; Gender Studies; Pedagogik; Education; Biologi; Biology;

    Sammanfattning : Higher education biology is a natural science discipline that is numerically female biased on undergraduate level across most international contexts. In Sweden, Germany, and the UK, for example, more than 60% of all undergraduate students are women. LÄS MER

  3. 2. Pressure driven instabilities in the reversed-field pinch : numerical and theoretical studies

    Författare :Ahmed Akram Mirza; Jan Scheffel; Roberto Paccagnella; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fusion plasma; thermonuclear; Reversed-field pinch; resistive MHD; resistive g modes; thermal conduction; the boundary value theory;

    Sammanfattning : According to classical linearized resistive magnetohydrodynamics theory, pressuredriven modes are unstable in the reversed-field pinch (RFP) due to unfavorable magnetic field line curvature. The result is based on the assumption of an adiabatic energy equation where anisotropic thermal conduction effects are ignored as compared to convection and compression. LÄS MER

  4. 3. Mechanics of Nanocellulose Foams : Experimental and Numerical Studies

    Författare :Prashanth Srinivasa; Artem Kulachenko; Laurent Orgéas; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Nanofibrillär cellulosa (NFC) skum är en intressant klass av cellulära material med möjliga applikationer som sträcker sig från fordonsindustrin till biomedicin då det har unika och önskvärda mekaniska egenskaper. I ljuset av de senaste framstegen inom framställning av skum förutspås det tillämpas inom en rad olika områden, inklusive områden där dess mekaniska egenskaper är viktiga. LÄS MER

  5. 4. Residual and Solubility trapping during Geological CO2 storage : Numerical and Experimental studies

    Författare :Maria Rasmusson; Fritjof Fagerlund; Auli Niemi; Jonathan Ennis-King; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; capillary trapping; CCS; convective flow; CO2; light transmission; SO2; well test; Hydrology; Hydrologi;

    Sammanfattning : Geological storage of carbon dioxide (CO2) in deep saline aquifers mitigates atmospheric release of greenhouse gases. To estimate storage capacity and evaluate storage safety, knowledge of the trapping mechanisms that retain CO2 within geological formations, and the factors affecting these is fundamental. LÄS MER

  7. 5. Models in Neutrino Physics : Numerical and Statistical Studies

    Författare :Johannes Bergström; Tommy Ohlsson; Pilar Hernandez; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neutrino mass; lepton mixing; Majorana neutrinos; neutrino oscillations; neutrinoless double beta decay; statistical methods; Bayesian inference; model selection; effective field theory; Weinberg operator; seesaw models; inverse seesaw; right-handed neutrinos; renormalization group; threshold effects.; Neutrinomassor; leptonblandning; Majorananeutriner; neutrinooscillationer; neutrinol¨ost dubbelt betas¨onderfall; statistiska metoder; Bayesisk inferens; modellval; effektiv f¨altteori; Weinbergoperator; seesawmodeller; invers seesaw; högerhänta neutriner; renormeringsgrupp; tröskeleffekter.;

    Sammanfattning : The standard model of particle physics can excellently describe the vast majorityof data of particle physics experiments. However, in its simplest form, it cannot account for the fact that the neutrinos are massive particles and lepton flavorsmixed, as required by the observation of neutrino oscillations. LÄS MER
