  1. 1. A methodology for operations-based safety appraisal of two-lane rural highways : Application in Uganda

    Författare :Godfrey Mwesige; Harilaos Koutsopoulos; Basil Psarianos; KTH; []
    Nyckelord :passing zones; passing rate; collision risk; accepted gap; time-to-collision; passing sight distance; two-lane rural highways; Uganda; Transportvetenskap; Transport Science;

    Sammanfattning : The majority of the road infrastructure in developing countries consists oftwo-lane highways with one lane in each travel direction. Operational efficiency of these highways is derived fromintermittent passing zones where fast vehicles are permitted by design to pass slow vehicles using the opposite traffic lane. LÄS MER

  3. 2. Melanophore signaling : regulation and application

    Författare :Tony P. M. Andersson; Ethan Lerner; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Melanophores are pigment-containing cells responsible for quick physiological color changes in lower vertebrates due to redistribution of melanosomes, pigment granules. We have studied melanophores from African clawed frog, Xenopus laevis. LÄS MER

  4. 3. Polymer-shelled Ultrasound Contrast Agents : Characterization and Application

    Författare :Dmitry Grishenkov; Leif Kari; Lars-Åke Brodin; Michel Versluis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ultrasound; contrast agents; microbubbles; polymer; perfusion; Acoustics; Akustik; Material physics with surface physics; Materialfysik med ytfysik; Cardiovascular medicine; Kardiovaskulär medicin; Cardiology; Kardiologi;

    Sammanfattning : Ultrasound-based imaging technique is probably the most used approach for rapid investigationand monitoring of anatomical and physiological conditions of internal organs and tissues.Ultrasound-based techniques do not require the use of ionizing radiation making the tests anexceptionally safe and painless.

  5. 4. Decentralized Application Security

    Författare :Per Hallgren; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Decentralization; Homomorphic Encryption; Location-Based Services; Privacy;

    Sammanfattning : On the internet today, everything is centralized. For most people, a single commercial entity owns the power to disclose all their personal emails. Most commonly your emails are only disclosed to you and your correspondent, but the power to choose who sees these emails is in fact not yours. LÄS MER

  7. 5. The three-component aza-Baylis-Hillman reaction : development and application

    Författare :Daniela Balan; Hans Adolfsson; Varinder Aggarwal; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi;

    Sammanfattning : The current thesis presents the optimization and generalization of the Baylis-Hillman reaction applied to in situ generated imines, i.e. a three-component aza- Baylis-Hillman reaction. We found that the title reaction proceeds most efficiently in the presence of a combination of catalysts, i. LÄS MER
