  2. 1. Safety Culture in Sea and Aviation Transport

    Author : Åsa Ek; Ergonomi och aerosolteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; organizational climate; air traffic control; safety culture; passenger shipping; airport ground handling; Social sciences; Samhällsvetenskaper; Development psychology; Utvecklingspsykologi; Applied and experimental psychology; Tillämpad och experimentell psykologi; Technological sciences; Teknik; Säkerhetsteknik; Safety technology;

    Abstract : The research presented in this thesis investigates sea and aviation transport safety culture, with a focus on perceptions and attitudes. A safety culture reflects the attitudes, beliefs, perceptions, and values that individuals share in relation to safety. READ MORE

  4. 2. Mass Spectrometry with Electrospray Ionization from an Adjustable Gap

    Author : Patrik Ek; Åsa Emmer; Johan Roeraade; Per M. Claesson; Ulrika Nilsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electrospray ionization; mass spectrometry; nanoelectrospray; ESI; MS; chip; emitter; gap; liquid bridge; nozzle; peptides; Analytical chemistry; Analytisk kemi;

    Abstract : In this thesis the fabrication and analytical evaluation of two new electrospray emitters utilized for mass spectrometry analysis is presented. The emitters are based on a new concept, where the spray orifice can be varied in size. The thesis is based on two papers. All present-day nanoelectrospray emitters have fixed dimensions. READ MORE

  5. 3. New methods for sensitive analysis with nanoelectrospray ionization mass spectrometry

    Author : Patrik Ek; Johan Roeraade; Åsa Emmer; Andries P. Bruins; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mass spectrometry; electrospray ionization; nanoelectrospray ionization; adjustable gap; emitter; miniaturization; improved sensitivity; nanoliter picoliter sample volumes; Alzheimer’s disease; amyloid-beta Aβ ; Analytical chemistry; Analytisk kemi;

    Abstract : In this thesis, new methods that address some current limitations in nanoelectrospray mass spectrometry (nESI-MS) analysis are presented. One of the major objectives is the potential gain in sensitivity that can be obtained when employing the proposed techniques. READ MORE

  6. 4. Use of Recombinant Allergens for Component-Resolved Diagnostics (CRD) in IgE-Mediated Allergy

    Author : Åsa Marknell DeWitt; Pia Ek; Jonas Lidholm; Ronald van Ree; Uppsala universitet; []
    Keywords : Biomedical laboratory science; recombinant allergen; IgE; component-resolved diagnostics; CRD; tropomyosin; Phl p 11; Phl p 4; Pen a 1; Hev b 5; Biomedicinsk laboratorievetenskap;

    Abstract : Immunoglobulin E (IgE)-mediated allergy occurs when our immune system causes a reaction to otherwise harmless substances (allergens). Allergens are predominantly proteins present in biological materials such as pollens, mites, animal epithelia, moulds and foods. READ MORE

  7. 5. Bark Biorefinery : Isolation, Characterization and Application

    Author : Isabella Kwan; Monica Ek; Åsa Emmer; Anette Larsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Sustainability; bark; biorefinery; Norway spruce; nanocellulose; Pickering emulsion; organosolv; extraction; lignin; Hållbarhet; bark; bioraffinaderi; gran; nanocellulosa; Pickering emulsioner; organosolv; extraktion; lignin; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : To fulfill the United Nations’ 17 sustainable development goals, there is a need to transition from a petroleum-based society toward a more sustainable one which requires new solutions and the production of materials, chemicals, and energy from renewable resources. Using side-stream products from industries to produce value-added products will be economically beneficial. READ MORE
