  2. 1. Physical Activity, Bone Mass and Bone Structure in Pre-pubertal Children

    Author : Gayani Alwis; Ortopedi - klinisk och molekylär osteoporosforskning; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone size; BMD; BMC; hip structure analysis; DXA; boys; Physical activity; girls; acclerometers; school transportation;

    Abstract : Low bone mineral density (BMD) is a risk factor for fractures and much of the fracture preventive effort today is devoted to preventing low BMD. Physical activity (PA) has been described as one of the best strategies to optimize skeletal development in the growing child. READ MORE

  4. 2. Allograft bone in hip revision: the effect of locally applied pharmacological treatment

    Author : Ola Belfrage; Lund Ortopedi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; allograft bone; bone transplantation; bisphosphonate; bone morphogenetic proteins; hip revision; radiostereometric analysis;

    Abstract : The clinical success of primary hip replacement is paramount but the need for revisions will continue to increase due to the increasing number of operated individuals. In Sweden, the number of hip revisions in 2012 exceeded 2,300. During implant loosening, some of the bone in the femur is lost, which can make the revision more difficult. READ MORE

  5. 3. Structure and properties of FeAl as influenced by processing

    Author : HELENA SKOGLUND; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EDS; mechanical alloying; FeAl; Al2O3 precipitates; boron-doping; powder processing; diffusion; vacancies; mechanical properties; hardening mechanisms;

    Abstract : Iron aluminides are candidate materials for a sustainable society since they are composed of abundant metals and have excellent corrosion properties in combination with high specific strength. However, there are some drawbacks that limit the practical use, e.g. low RT ductility and a drop in strength at high temperature. READ MORE

  6. 4. Depth Profiling of the Passive Layer on Stainless Steel using Photoelectron Spectroscopy

    Author : Wendy Fredriksson; Kristina Edström; Fredrik Björefors; Sannakaisa Virtanen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; depth profile; stainless steel; passive film; XPS; HAXPES; corrosion; powder metallurgical; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : The physical properties of the protective passive films formed on the surface of stainless steels under electrochemical polarization in different electrolytes were studied. The structure of these films was analyzed as a function of depth using photoelectron spectroscopy (PES). READ MORE

  7. 5. Antimicrobial peptides as defense molecules at the interface of the host and bacteria

    Author : Ulf Meyer-Hoffert; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Microbes surround us. However, most of the time we are unaware of them. Our epithelial surfaces, which provide the physical barrier and separate us from the environment, are usually free of signs of a battle taking place. READ MORE
