  2. 1. Bracing of steel bridges during construction; theory, full-scale tests and simulations

    Author : Hassan Mehri; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bracing; steel-concrete composite; steel; bridge; test; construction; laboratory; experiment; experimental; theory;

    Abstract : A number of steel bridges have suffered lateral-torsional failure during their construction due to their lacking adequate lateral and/or rotational stiffness. In most cases, slight bracing can be of great benefit to the main girders involved through their controlling out-of-plane deformations and enabling the resistance that is needed to be achieved.

  4. 2. Multi-level Interactions between Fisheries and Trade : Modeling intertwined social-ecological systems

    Author : Laura G. Elsler; Schlüter Maja; Florian Diekert; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; multi-level interactions; social-ecological model; trade relationships; complexity; inequality in fisheries; fisheries sustainability; seafood trade; international markets; fisheries collapse; Sustainability Science; vetenskap om hållbar utveckling;

    Abstract : Sustainable and equitable fisheries are central for addressing the challenges of the UN Sustainable Development Goal 14: Life Below Water. International trade, once presented by Walrasian economists as a panacea for fisheries development, has not markedly decreased poverty and has been related to the overexploitation of marine species.

  5. 3. Holistic approach in engineering design - controlling risks from accidental hazards in bridge design

    Author : Ivar Björnsson; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; design; codes; accidental; extreme; bridges; holistic; approach; robustness; risk; reliability; uncertainty;

    Abstract : Engineering design, in concise terms, is what engineers do using what they know. It is the underlying decision making activity that determines what is to be built and how it should be built. An ever present requirement in engineering design is that the structure should be safe.

  6. 4. Mechanical circulatory support in patients with severe heart failure

    Author : Hans Lidén; Göteborgs universitet; []
    Keywords : ;

    Abstract : Severe heart failure has a poor prognosis. Mechanical circulatory support (MCS) is capable of assisting the circulation in selected patients to bridge them to heart transplantation or recovery of heart function. MCS is manufactured in short-term or long-term designs. READ MORE

  7. 5. Resuscitative endovascular balloon occlusion of the aorta : Physiology and clinical aspects of an emerging technique

    Author : Mitra Sadeghi; Tal M. Hörer; Kristofer F. Nilsson; Per Skoog; Kjell Jansson; Kevin Mani; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; REBOA; trauma; hemorrhage; partial REBOA; Ischemia reperfusion injury; blood pressure titration; endtidal cabondioxide; traumatic inflammatory response;

    Abstract : Traumatic hemorrhagic shock is a major cause of death worldwide. Patients enter the fatal triad of hypothermia, acidosis and coagulopathy and die quickly due to cardiovascular collapse. Ideally, procedures should be performed at the injury scene to prevent this fatal event. READ MORE
