  1. 1. Concrete pavements’ repair techniques and numerical assessment of dowel bar load transfer efficiency

    Author : Saima Yaqoob; Johan Silfwerbrand; Larissa Strömberg; Anne Beeldens; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete pavements; Rapid repair; Precast slabs; Dowel bar; Load transfer efficiency; Betongbyggnad; Concrete Structures;

    Abstract : Concrete pavements are a suitable alternative for high-traffic volume roads, concentrated loads and roads exposed to severe weather conditions. In Sweden, among other reasons, the scarcity of concrete pavements is attributed to the need for more national knowledge and expertise in the field. READ MORE

  2. 2. DNA repair and the p53 pathway in ischemic and traumatic brain injury

    Author : Gregor Tomasevic; Neurokirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuronal death; DNA repair; knock-out mice; XPA; p53; mRNA; hippocampus; preconditioning; hypothermia; trauma; Brain; ischemia; neurobehavior; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Abstract : Ischemic and traumatic brain damage are major causes of disability and death. While much effort has been spent to develop pharmacological treatments for these conditions, no neuroprotective drugs are in clinical use. READ MORE

  3. 3. Biodegradable magnesium implants, immunomodulation, and tissue repair/regeneration

    Author : Heithem Ben Amara; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adipose tissue; Biodegradable implants; Bone–implant interface; Bone marrow; Inflammation; Cellular mechanotransduction; Gene expression; Immunohistochemistry; Magnesium; Neovascularization; Osseointegration; Soft tissue injuries;

    Abstract : The century-old paradigm of holding fractures with a metallic implant to enable bone repair, known as osteosynthesis, is still used today without alteration. Patients are increasingly being treated with metallic implants made of magnesium (Mg) that secure osteosynthesis and are reabsorbed in situ without the surgical re-entry that requires their permanent analogs.

  4. 4. Railway wheel steel behaviour upon thermo-mechanical loadings

    Author : Erika Steyn; Chalmers tekniska högskola; []
    Keywords : 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; residual stress; thermo-mechanical fatigue; railway wheel steel; pearlitic microstructure; severe block braking; repair welding;

    Abstract : Optimised railway maintenance techniques such as rail grinding and milling, or rail repair welding, are vital to more sustainable rail networks. As demands on the railway increases, the need to better understand the material behaviour during local heating events occurring during maintenance is amplified. READ MORE

  5. 5. Bone Enhancement with BMP-2 for Safe Clinical Translation

    Author : Marta Kisiel; Jöns Hilborn; Monica Wiig; Richard Oreffo; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bone repair; Bone healing; Bone morhogenetic protein-2; Osteogenesis; Extracelular matrix; Hyaluronan; Animal model; Orthopaedics; Ortopedi; Engineering Science with specialization in Materials Science; Teknisk fysik med inriktning mot materialvetenskap;

    Abstract : Bone morphogenetic protein-2 (BMP-2) is considered a promising adjuvant for the treatment of bone regeneration. However, BMP-2 delivery in a conventional collagen scaffold needs a high dose to achieve an effective outcome. Moreover, such dosage may lead to serious side effects. READ MORE
