  2. 1. Biomolecular Recognition Based on Field Induced Magnetic Bead Dynamics

    Author : Rebecca Stjernberg Bejhed; Peter Svedlindh; Klas Gunnarsson; Maria Strömme; Teresa Zardán Gómez de la Torre; Christer Johansson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Magnetic biosensor; magnetic nanoparticle; DNA detection; Teknisk fysik; Engineering Science;

    Abstract : In this thesis, three different read-out techniques for biomolecular recognition have been studied. All three techniques rely on the change in dynamic behaviour of probe functionalised magnetic beads after binding to a biomolecular target complementary to the probe. READ MORE

  4. 2. Feeling and Thinking at Work : Personal and Collective Work-Identity Predictions and Formations

    Author : Ola Nordhall; Igor Knez; Johan Willander; Per Lindberg; Fredrik Saboonchi; Kerstin Isaksson; Högskolan i Gävle; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; personal and collective work-identity; emotion; cognition; work motivation; organizational pay justice; general mental health; exhaustion; teachers’ psy-chosocial working conditions; work-identity formation; personlig och kollektiv arbetsidentitet; emotion; kognition; arbetsmotivation; organisatorisk lönerättvisa; allmän mental hälsa; utmattning; lärares psykosociala arbetsvillkor; arbetsrelaterad identitetsformation; Health-Promoting Work; Hälsofrämjande arbete;

    Abstract : The aim of the present thesis was to investigate emotional and cognitive personal and collective work-identity in predicting employees’ work-related motivation, organizational justice perceptions, general mental health and exhaustion; as well as if psychosocial working conditions might explain some of these relationships. Emotion and cognition in formation of personal and collective work-identity were also investigated. READ MORE

  5. 3. On-line Sample Pretreatment Based on Membrane Enrichment, Mainly Using Supported Liquid Membranes, for Chromatographic Analysis

    Author : Yin Shen; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biological Sample; Environmental Sample; Capillary Gas Chromatography; Ion Chromatography; Automation; Sample Pretreatment; Enrichment; Membrane; Extraction; Analytical chemistry; Analytisk kemi;

    Abstract : The main objective of this work was to construct practical analytical systems for the analysis of environmental and biological samples, using membrane-based techniques for sample pretreatment and chromatography for final analysis. Two types of membrane processes have been applied, with emphasis on automation. READ MORE

  6. 4. On-chip Ultrasonic Sample Preparation

    Author : Ida Sadat Iranmanesh; Martin Viklund; Johan Nilsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ultrasound; Sample preparation; Particle manipulation; Fysik; Physics; Biological Physics; Biologisk fysik;

    Abstract : Acoustofluidics has become a well-established technology in the lab-on-a-chip scientific community. The technology involves primarily the manipulation of fluids and/or particles in microfluidic systems. READ MORE

  7. 5. Occurrence of Traffic-Derived Microplastics in Different Matrices in the Road Environment

    Author : Ida Järlskog; Yvonne Andersson-Sköld; Stephan Wagner; Statens väg- och transportforskningsinstitut; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; non-exhaust particles; tire wear particles; road dust; automated SEM EDX; environmental samples; optimized sample preparation; organic pollutants; street sweeping; traffic-derived microplastics; road simulator;

    Abstract : The prevalence of microplastic contamination has raised concerns about the potential risk and impact on the global environment. Traffic-derived microplastics, i.e., tire wear particles (TWP), polymer-modified bitumen, and road markings contribute to the emissions, and TWP are assumed to be one of the largest sources of microplastic emissions.
