  1. 1. Lab work in science education : Instruction, inscription, and the practical achievement of understanding

    Författare :Oskar Lindwall; Berner Lindström; Tim Koschmann; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Lab work; science education; educational technology; classroom interaction; ethnomethodology; naturvetenskapliga laborationer; IT i utbildning; klassrumsstudier; etnometodologi; Education; Pedagogik;

    Sammanfattning : Taking an analytical perspective founded on ethnomethodology and conversation analysis, the four studies presented in this thesis provide detailed analyses of video recorded lab work in mechanics at secondary and university level. The investigated activities all build on educational design afforded by a technology called probeware. LÄS MER

  4. 3. Towards Myosin Powered Lab-on-a-Chip Devices

    Författare :Lasse ten Siethoff; Alf Månsson; Miklos Kellermayer; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; myosin; actin; molecular motors; lab-on-a-chip; nanobiotechnology; bionanotechnology; diagnostics; nanowires; nanowire arrays; Biomedical Sciences; Biomedicinsk vetenskap;

    Sammanfattning : Myosins are protein motors that use chemical energy in the form of adenosinetriphosphate to produce force and motion. These molecular motors might be usedto power transportation in Lab-on-a-chip devices where a series of laboratory tasks(e.g. separation, concentration and detection) are performed in one sequence on asmall chip.

  5. 4. Exploring the Potential of Head Worn Displays for Manual Work Tasks in Industrial Environments

    Författare :Sebastian Felix Rauh; Cristian Bogdan; Gerrit Meixner; Mario Romero Vega; Alex Olwal; Mark Smith; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Head Worn Displays; Work Support; Augmented Reality; Computer Science; Datalogi; Human-computer Interaction; Människa-datorinteraktion;

    Sammanfattning : In this thesis I explore the potential of modern Head-Worn Displays for aiding manual work tasks in the manufacturing industries. In such settings, workers are already supported by using mobile hand-held devices that show instructions and enable the worker to document work tasks. LÄS MER

  7. 5. Acclimation of plants to combinations of abiotic factors : connecting the lab to the field

    Författare :Zsofia Réka Stangl; Vaughan Hurry; Lisa Ainsworth; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nitrogen; carbon dioxide; temperature; thermal acclimation; mycorrhiza; boreal forest; climate change; C:N balance; allocation; respiration; photosynthesis; terrestrial biosphere model;

    Sammanfattning : Increasing atmospheric CO2 and other greenhouse gasses coupled to the accelerated rate of global warming puts plants and ecosystems under the strain of a rapidly changing abiotic environment. Understanding the impacts of changing global climate is a strong focus of plant science and the establishment of more resilient crop variants is an important goal for breeding programs. LÄS MER
