  1. 1. Residual stresses, fatigue and deformation in cast iron

    Författare :Mattias Lundberg; Johan Moverare; Ru Lin Peng; Taina Ahmad; Daniel Bäckström; Maqsood Ahmad; Sten Johansson; Mattias Calmunger; Peter Hedström; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The complex geometry of cylinder heads in heavy-duty diesel engines makes grey iron or compact graphite iron a preferred material choice due to its price, castability, thermal conductivity and damping capacity. Today’s strict emission laws have increased the demands on engine performance and engine efficiency. LÄS MER

  3. 2. Peri-implantitis : risk factors and outcome of reconstructive therapy

    Författare :Ahmad Aghazadeh; Stefan Renvert; Andreas Stavropoulos; Rutger Persson; Ingemar Abrahamsson; Malmö universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : This thesis is focused on (I) the outcome of reconstructive treatment of peri-implant defects and (II) risk factors for the development of peri-implantitis.BackgroundAn increasing number of individuals have dental implant-supported reconstructions. The long-time survival rate of dental implants is good, but complications do occur. LÄS MER

  4. 3. Identification of genetic biomarkers for the risk prediction of recurrent venous thromboembolism. Risk prediction of recurrent VTE

    Författare :Abrar Ahmad; Allmänmedicin och klinisk epidemiologi; []
    Nyckelord :Recurrent venous thromboembolism; Genetic risk score; Multibiomarker;

    Sammanfattning : Background: Venous thromboembolism (VTE) is the third most frequent life-threatening cardiovascular disease with an annual incidence rate of 1-2 per 1000 person-years. After the diagnosis for primary VTE, about 20-30% patients develop a recurrence within 5-years. LÄS MER

  5. 4. New insights into plant amino acid transport and its contribution to nitrogen nutrition

    Författare :Iftikhar Ahmad; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Nitrogen (N) is a crucial element for plant growth and development, as it is a key constituent of numerous plant metabolites and structural components. However, most plant N is in the form of amino acids, which are building blocks of proteins, precursors of many secondary metabolites and the “currency” of N within plants (i.e. LÄS MER

  7. 5. Regulatory networks of c-di-GMP signalling involved in biofilm formation, motility and host pathogen interactions in Salmonella typhimurium

    Författare :Irfan Ahmad; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Adaptation to altered environmental conditions is one of the fundamental bacterial characteristics. The ubiquitous second messenger c-di-GMP plays a key role to adopt bacterial behaviour. Transition from motility to sessility and from acute infection to chronic infection is regulated by c-di-GMP signalling in many bacteria. LÄS MER
