  1. 1. Technology in Absentia : A New Materialist Study of Digital Disengagement

    Författare :Cristina Ghita; Claes Thorén; Mats Edenius; Jenny Eriksson Lundström; Magnus Mähring; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; digital disengagement; diffractive digital use; ethnography; new materialism; technology non-use; digital disconnection; digital detox; Information Systems; Informationssystem;

    Sammanfattning : The rhetoric associated with society-wide digitalisation promises benefits such as increased quality of life, democracy, or sustainability, which point towards normative trajectories of increased automation and digitalisation of nearly all aspects of society. Meanwhile, there is evidence of a disenchantment with digital use, forming a movement that challenges the pervasiveness of digital artefacts such as the smartphone. LÄS MER

  3. 2. Dynamic and Static Diffractive Optics - some Examples

    Författare :Björn Löfving; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; subwavelength grating; spatial light modulator; phase retrieval; diffractive optics; ferroelectric liquid crystal; analog-to-digital conversion; optical switch; feedback generated hologram;

    Sammanfattning : Diffractive optics is a modern branch of optics, that exploits microstructures to manipulate the propagation of light. Fast computers and the progress in manufacturing technique of microelectronics have made possible a rapid development of diffractive optics during the past 10 years. LÄS MER

  4. 3. Structural Studies of Large dsDNA Viruses using Single Particle Methods

    Författare :Hemanth Kumar Narayana Reddy; Martin Svenda; Sarah Butcher; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PR772; phage; PRD1; Bacteriophage; coliphage; Melbournevirus; Cedratvirus; lurbo; Pithovirus; CryoEM; Single particle imaging; Coherent; Diffractive; Imaging; Soft X-ray; Microscopy; Microscope; GDVN; High resolution; XFEL; aerosol; Injection; electrospray; gas dynamic virtual nozzle; CDI; CXI; FEL; Chemistry with specialization in Biophysics; Kemi med inriktning mot biofysik;

    Sammanfattning : Structural studies of large biological assemblies pose a unique problem due to their size, complexity and heterogeneity. Conventional methods like x-ray crystallography, NMR, etc. are limited in their ability to address these issues. To overcome some of these limitations, single particle methods were used. LÄS MER

  5. 4. Treåringar, kameror och förskola – en serie diffraktiva rörelser

    Författare :Lena O Magnusson; Claes Eriksson; Tarja Karlsson Häikiö; Hillevi Lenz Taguchi; Högskolan i Gävle; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; digital camera; young children; pre-school; aesthetics; gaze; photography; ethics; agential realism; intra-action; diffraction; Innovative Learning; Innovativt lärande; digital camera; young children; pre-school; aesthetics; gaze; photography; ethics; agential realism; intra-action; diffraction;

    Sammanfattning : The aim of this thesis is to examine what happens when three-year-olds are given access to digital cameras, and what shape and form children’s photographic capacity takes within the framework of everyday pre-school activities. The notion that young children in pre-school rarely get to use cameras themselves, and that they take part in photographs produced by pre-school educators as part of an ongoing documenting practice rooted in the curriculum is the point of departure.
