    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asphalt concrete; dynamic modulus; non-contact excitation; resonance testing; thermally induced damage; viscoelasticity; Asfaltbetong; beröringsfri excitation; resonansfrekvens; resonansprovning; styvhetsmodul; Building Materials; Byggnadsmaterial;

    Abstract : Thetemperature induceddamage in asphalt mixtureshas always been a major distress that requires a substantialconsiderationin the asphalt industry. One of the most important aspects of studying temperature induceddamage is developing a practical test method for evaluation of the material’s resistanceto it. READ MORE

  4. 2. Application of Automated Non-contact Resonance Testing for Low Temperature Behavior of Asphalt Concrete

    Author : Abiy Bekele; Nils Ryden; Safwat Said; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Resonance testing; stiffness modulus; asphalt concrete; Non-contact excitation; Resonance frequency; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : Impact resonance testing is a well-documented non-destructive testing method and its applications on asphalt concrete have also been implemented successfully. The test is carried out manually by inducing an impact in order to excite the test specimen and taking measurements of the vibrational response. READ MORE

  5. 3. Pharmacokinetic and pharmacogenetic aspects of drug-drug interactions between antiretroviral and anti-tuberculosis drugs in Ethiopian patients : implication for optimization of TB-HIV co-treatment

    Author : Abiy Habtewolde Eyakem; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : TB and HIV are immuno-pathologically interacting epidemic infectious diseases affecting the lives of millions globally & sub-Saharan African region accounts the highest burden of both diseases. Although effective therapies are available for the management of each, TB-HIV co-treatment has faced challenges mainly due to drug-drug interactions & overlapping drug toxicities. READ MORE
