  5. 3. Genetic Factors and Dietary Salt Intake as Determinants of Blood Pressure and Risk of Primary Hypertension

    Author : Fredrik Wowern; diabetes och endokrinologi Genomik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood Pressure; Kardiovaskulära systemet; Cardiovascular system; Genetics; Salt; Hypertension;

    Abstract : Blood pressure (BP) and development of hypertension (HT) are determined by both genetic and environmental factors. The specific genetic etiology of these two entities has remained enigmatic despite large efforts. In addition, daily salt intake seems to predispose for certain individuals to develop HT. READ MORE

  6. 4. Synthesis and characterization of nanocarbons as reinforced particles in metal composites

    Author : Vicente Benavides; Alberto Vomiero; Frank Mücklich; Olga Chernogorova; Jordi Ibañez Inza; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanocarbons; super elastic hard carbon; Fullerenes under pressure; Disordered carbon; Experimentell fysik; Experimental Physics;

    Abstract : In this work, several scientific problems related to high pressure–high temperature (HP–HT) synthesis of new materials using fullerite as a precursor were studied: first, the mechanism of the transformation of C60 crystal into a nano-clustered graphene phase (NGP) at a pressure of 8 GPa; and second, the effect of disorder introduced into C60 crystals by ball milling prior to HP–HT synthesis on the structure and properties of the NGP. A separate set of experiments was devoted to compression of C60 precursor at unexplored before pressure of 25 GPa and elevated temperatures in search for new type of disordered carbon-based materials.

  7. 5. Experimental studies of turbulent boundary layer separation and control

    Author : Kristian Angele; KTH; []
    Keywords : turbulence; boundary layer; separition; adverse pressure graddient;

    Abstract : The object ofthe present work is to experimentally study thecase ofa turbulent boundary layer subjected to an AdversePressure Gradient (APG) with separation and reattachment. Thisconstitutes a good test case for advanced turbulence modeling. READ MORE
