  1. 16. Momentum exchange between light and nanostructured matter

    Författare :Daniel Andrén; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase-gradient metasurface; optical force and torque; metavehicle; momentum exchange.; nano-optics; rotary nanomotor; optical tweezers;

    Sammanfattning : An object's translational and rotational motion is associated with linear and angular momenta. When multiple objects interact the exchange of momentum dictates the new system's motion. LÄS MER

  3. 17. Experimental Design and Evaluation of Biocide Release from Microcapsules

    Författare :Jonatan Bergek; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; microsphere; microscopic and macroscopic porosity; controlled release; internal phase separation method; Microcapsule; biocide; polyelectrolyte multilayer;

    Sammanfattning : To protect a painted house façade from mold or algae, anti-growth agents are usually mixed in the paint. The protection of paint systems used in the past relied on heavy metals for protection and are banned today due to their negative impact on the environment. LÄS MER

  4. 18. Platelet dysfunction in diabetes mellitus : impact of hyperglycemia and glycoprotein GPIIb/IIIa inhibition

    Författare :Masoud Razmara; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Diabetes mellitus (DM) is associated with increased cardiovascular morbidity and mortality, due to diabetic angiopathy. Hyperglycemia is one of the factors that may cause platelet dysfunction in diabetic patients. This work investigated mechanisms underlying hyperglycemia-induced platelet dysfunction, and its impact in DM patients. LÄS MER

  5. 19. Hemostasis and microvascular function in type 1 diabetes : effects of treatment with statin and aspirin

    Författare :Sara Tehrani; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Patients with type 1 diabetes often develop microvascular complications and are at increased risk of premature cardiovascular disease. Women with type 1 diabetes lack the normal female protection against cardiovascular disease and may even be at higher risk compared with men with type 1 diabetes. LÄS MER

  7. 20. Studies of clinical and haemostatic features associated with antiphospholipid antibodies

    Författare :Anna Vikerfors; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Antiphospholipid antibodies (aPL) are associated with a heterogeneous range of clinical conditions with predisposition for thrombosis, pregnancy morbidity and other autoimmune disorders, most frequently systemic lupus erythematosus (SLE). Both the clinical manifestations themselves and their treatment may be harmful to the affected individuals and aPL testing is still controversial. LÄS MER
