    Författare :Satya V.V.N. Kothapalli; Dmitry Grishenkov; Lars-Åke Brodin; Andreas Michael Versluis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nano-engineered microbubbles; SPION nanoparticles; Acoustic characterization of MBs; Fracturing mechanism of MBs; Opto-acoustics; Acoustophoresis; Physics; Fysik; Järnvägsgruppen - Ljud och vibrationer; Järnvägsgruppen - Ljud och vibrationer; Teknik och hälsa; Technology and Health;

    Sammanfattning : Diagnostic ultrasound (US) is safer, quicker and cheaper than other diagnostic imaging modalities. Over the past two decades, the applications of US imaging has been widened due to the development of injectable, compressible and encapsulated microbubbles (MBs) that provide an opportunity to improve conventional echocardiographic imaging, blood flow assessment and molecular imaging.

    Sammanfattning : Information and communication technologies (ICT) have experienced a technological convergence. Laptops, tablets and smartphones integrate previously distinct artefacts and communication protocols within information systems, personal computers and telephony. LÄS MER

  4. 18. Digital technologies as support for learning about the marine environment: Steps toward ocean literacy : Digital technologies and ocean literacy

    Författare :Geraldine Fauville; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; digital technologies; social media; ocean literacy; communication; science education; environmental education; sociocultural theory;

    Sammanfattning : Over the last century the ocean has been negatively impacted by human activities. In order to continue benefitting from marine services and goods, and the qualities afforded to human life through the ocean, citizens need to be informed about their relationship to the ocean and their own impact on it, that is they need to be ocean literate.

  5. 19. Energy in supermarkets - An overview on the energy flows and refrigeration controls

    Författare :Tommie Månsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The electrical energy used by supermarkets represents approximately 3% of Sweden's annual energy use. Of this, the refrigeration system accounts for 50%. To reduce greenhouse gases introduced by energy generation, a larger share of renewable energy sources must be implemented. LÄS MER

    Sammanfattning : Food packaging should ensure the safety and quality of food, minimize spoilage and provide an easy way of storing and handling it. Barrier coatings are generally used to meet the demands placed on fibre-based food packages, as these have the ability to regulate the amount of gases that can enter them. LÄS MER
