  1. 1. Kvinna i byggbranschen : civilingenjörers erfarenheter ur genusperspektiv

    Författare :Annicka Cettner; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : This thesis is a gender analysis based on women's experiences of working as engineers in the construction industry. It focuses on the women's working conditions, and their possibilities to make a career in construction. The question is why many women engineers choose to leave construction after an expensive education. LÄS MER

  3. 2. New approaches to moisture determination in complex matrices based on the Karl Fischer Reaction in methanolic and non-alcoholic media

    Författare :William Larsson; Anders Cedergren; Heinz-Dieter Isengard; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Karl Fischer titration; non-alcoholic reagent; trace moisture determination.; Analytical chemistry; Analytisk kemi;

    Sammanfattning : Vattenhaltsbestämning är av stor vikt i många sammanhang. T.ex. kan vattenhalten påverka utbytet av en kemisk syntes, eller ha negativ inverkan på hållbarheten av läkemedel och livsmedel. LÄS MER

  4. 3. Aqueous behaviour of characteristic molecules in the synthesis of porous silica materials : - an atomistic description

    Författare :Emelie Nilsson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; porous silica; struture directing agents; 29Si-NMR; neutron scattering; empirical potentail structure refinement; micelles;

    Sammanfattning : The formation process of porous silica materials is an intricate process, involving a number of components that interact to form a highly organized material. Both zeolites and mesoporous silica materials typically require the presence of organic structure director agents (SDAs) around which the silica network polymerizes. LÄS MER

  5. 4. Time-of-Flight Ion and Electron Spectroscopy: Applications and Challenges at Storage Ring Light Sources

    Författare :Christian Stråhlman; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This dissertation contains seven studies exploring novel instrumentation for ion and electron spectroscopy, including their applicability at storage ring light sources. The studies focus on instrumentation to study decay, dynamics and dissociation of photoexcited molecules, and the possibility to host such instruments at MAX~IV. LÄS MER

  7. 5. Bioanalysis using capillary electrophoresis and mass spectrometry : Applied on proteins, protein nanofibrils and polyvinyl alcohol microbubbles

    Författare :Leila Josefsson; Åsa Emmer; Ulrika Nilsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; : amyloid; capillary electrophoresis; contrast agents; detection; human blood plasma; ionic liquids; mass spectrometry; microbubbles; polyvinyl alcohol microbubbles; protein nanofibrils; proteins; Kemi; Chemistry;

    Sammanfattning : The sequencing of the genome of various species, including the human species, have led to increased understanding about how a protein structure is generated, and how specific structures are related to the proteins’ functionality. In paper I and II of this thesis, the folding of proteins in vitro to form hierarchical nanostructures, which in vivo often have a pathological effect, have been studied. LÄS MER
