  2. 1. Physiologically based modelling of nanoparticle biodistribution and biokinetics

    Author : Ulrika Carlander; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : To predict the toxicity of nanoparticles (1-100 nm), it is crucial to understand their biokinetics i.e. how they are taken up, distributed, dissolved and removed from the body. Such information can be gained from biodistribution studies in animals. READ MORE

  4. 2. Concrete Structures Subjected to Blast and Fragment Impacts - Numerical Simulations of Reinforced and Fibre-reinforced Concrete

    Author : Ulrika Nyström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SDOF; Concrete; fragment impact; weapon effects; fibre-reinforced concrete; blast wave; numerical simulations; reinforced concrete;

    Abstract : Concrete is widely used in design of protective structures due to its good energy-absorbing characteristics under high pressures and, when properly reinforced, ductile behaviour. Nevertheless, the response of concrete structures subjected to severe dynamic loading differs from their static behaviour, on a structural level but also on a material level. READ MORE

  5. 3. Arterial stiffness and risk factors for cardiovascular disease in young adults

    Author : Ulrika Fernberg; Anita Hurtig-Wennlöf; Maria Fernström; Bo Fernhall; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular disease; atherosclerosis; arterial stiffness; pulse wave analysis; intima media thickness; cardiorespiratory fitness; physical activity; body composition; young adults;

    Abstract : Atherosclerosis is a complex, chronic vessel wall disease that often leads to severe and acute cardiovascular diseases (CVD), such as myocardial infarction and stroke. CVD are the most common cause of death, both globally and in Sweden. READ MORE

  6. 4. Effects of physical exercise on coronary and peripheral vascular function. An integrative physiological study from rat to man

    Author : Ulrika Hägg Samuelsson; Göteborgs universitet; []
    Keywords : exercise; endothelial function; coronary flow velocity reserve; colour Doppler echocardiography; oxidative stress; gene expression; stiffness; ultrasound biomicroscopy;

    Abstract : Physical exercise is beneficial for the cardiovascular health. Numerous epidemiological studies reveal that physical activity reduces the risk of cardiovascular related death. Nevertheless, the underlying vessel wall specific physiological and molecular mechanisms still remain incompletely understood. READ MORE

  7. 5. Mass Spectrometry with Electrospray Ionization from an Adjustable Gap

    Author : Patrik Ek; Åsa Emmer; Johan Roeraade; Per M. Claesson; Ulrika Nilsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electrospray ionization; mass spectrometry; nanoelectrospray; ESI; MS; chip; emitter; gap; liquid bridge; nozzle; peptides; Analytical chemistry; Analytisk kemi;

    Abstract : In this thesis the fabrication and analytical evaluation of two new electrospray emitters utilized for mass spectrometry analysis is presented. The emitters are based on a new concept, where the spray orifice can be varied in size. The thesis is based on two papers. All present-day nanoelectrospray emitters have fixed dimensions. READ MORE
