  4. 17. Structured management of patients with suspected acute appendicitis

    Author : Manne Andersson; Roland Andersson; Conny Wallon; Ari Leppäniemi; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Background. Acute appendicitis (“appendicitis”) is one of the most common abdominal surgical emergencies worldwide. In spite of this, the diagnostic pathways are highly variable across countries, between centres and physicians. This has implications for the use of resources, exposure of patients to ionising radiation and patient outcome. READ MORE

  5. 18. Sustainable Recycling of Spent Lithium-ion Batteries : An In-situ Approach for Recovery and Alloying of Valuable Metals

    Author : Safoura Babanejad; Hesham Ahmed; Charlotte Andersson; Ari Jokilaakso; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Li-ion battery; black mass; Recycling; Pyrometallurgy; modeling; Process Metallurgy; Processmetallurgi;

    Abstract : A large number of Li-ion batteries used today will reach their End-Of-Life (EOL) in a few years. After their EOL, the recovery of their precious elements is required. By applying physical separation, a fraction with fine particle size is left behind which is known as Black Mass (BM). READ MORE

  6. 19. High-Resolution Seismics Methods Applied to Till Covered Hard Rock Environments
