1. 1. Carbides in martensitic medium carbon low alloyed tool steels studied with small angle scattering techniques, electron microscopy and atom probe tomography

   Författare :Erik Claesson; Peter Hedström; Hans Magnusson; Erik Offerman; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low alloyed tool steel; Martensite; Small angle scattering; Scanning transmission electron microscopy; Energy dispersive x-ray spectroscopy; atom probe tomography; Scanning precession electron diffraction; Precipitation; carbides; Tempering.; Materials Science and Engineering; Teknisk materialvetenskap;

   Sammanfattning : Medium carbon low alloyed tool steels are used today in various areas to shape plastics, nonferrous metals, and steels, and they are crucial in the manufacturing industry. To be effective, tool steels must be strong and tough, and have high wear resistance and temperature stability. LÄS MER

3. 2. Acute Myocardial Infarction: The Relationship between Duration of Ischaemia and Infarct Size in Humans - Assessment by MRI and SPECT

   Författare :Erik Hedström; Lund Klinisk fysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular system; Fysiologi; Physiology; humans; cardiac troponin T; creatine kinase isoenzyme MB; delayed contrast-enhanced magnetic resonance imaging; single photon emission computed tomography; myocardial perfusion; myocardial infarct size; myocardium at risk; duration of ischaemia; Kardiovaskulära systemet;

   Sammanfattning : The effect of duration of ischaemia on final infarct size is well established in animal studies, but not fully evaluated in humans. Delayed contrast-enhanced magnetic resonance imaging (DE-MRI) can be used to distinguish between viable and non-viable myocardium and thus to quantify infarct size. LÄS MER

4. 3. Fractures in children : a population-based study from northern Sweden

   Författare :Erik Hedström; Sead Crnalic; Ulrica Bergström; Piotr Michno; Lucie Laflamme; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Epidemiology; fracture; child; pediatric; injury; epidemiologi; Epidemiology;

   Sammanfattning : Fractures and other injuries are notoriously common in childhood and adolescence and a major cause of morbidity. They place a heavy burden on individuals, families, health systems and society. LÄS MER

5. 4. Materialitetens roller och förutsättningar i kommunal krisledning

   Författare :Martina Granholm; Erik A. M. Borglund; Lena-Marie Öberg; Karin Hedström; Mittuniversitetet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; crisis management; sensemaking; materiality; affordance; krisledning; meningsskapande; materialitet; affordans;

   Sammanfattning : Arbetet med denna licentiatavhandling har skett inom ramarna för det Interregionalt finansierade projektet Gränslös samverkan för ökad säkerhet 2. Syftet med avhandlingen har varit att fördjupa kunskapen om kommunal krisledning genom att också inkludera materialitetens medverkan i krisledningen och vilka förutsättningarna är för att de ska brukas.

7. 5. Cargo Cult in Agile Software Development

   Författare :Tanja Elina Havstorm; Fredrik Karlsson; Karin Hedström; Shang Gao; Kai Wistrand; Erik Perjons; Örebro universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Agile software development; cargo cult; deviations; ethnography; SDMCCT; social action theory; software development method; work motivation theory; theorizing;

   Sammanfattning : Software development (SD) projects are complex endeavors, and organizations employ software development methods (SDMs) both to add structure and to propel their projects. Nowadays, agile SDMs are the most used methods. LÄS MER
