  1. 1. Towards Practical Implementation of Phase-Sensitive Amplifier Based Transmission Systems

    Författare :Samuel L I Olsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase-sensitive amplification; four-wave mixing; nonlinear optical signal processing; optical injection locking; fiber nonlinearities; fiber optic parametric amplification;

    Sammanfattning : All commercially available optical amplifiers are so-called phase-insensitive amplifiers (PIAs) which degrade the signal-to-noise ratio (SNR) through the amplification process. This kind of amplifier has a quantum limited noise figure (NF) of 3 dB. LÄS MER

  3. 2. Towards a detailed understanding of the red blood cell storage lesion : and its consequences for in vivo survival following transfusion

    Författare :Andreas Hult; Christer Malm; Per-Arne Oldenborg; Martin L. Olsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Red blood cell; erythrocyte; transfusion; macrophage; phagocytosis; storage lesion; eryptosis; Class A scavenger receptor; transfusion medicine; transfusionsmedicin;

    Sammanfattning : Red blood cells (RBCs) are vital for oxygen delivery to tissues and constitute the vast majority of all cells in blood. After leaving the red bone marrow as mature cells, RBCs have a lifespan of approximately 120 days before they are removed from the circulation by macrophages, mainly in the spleen and liver. LÄS MER

  4. 3. Hyponatremia - Early differential diagnosis, management and prognosis

    Författare :Karin Olsson; Kardiovaskulär forskning - hypertoni; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hyponatremia; differential diagnosis; Biomarkers; apelin; vasopressin; Prognosis and survival; bioreactance;

    Sammanfattning : Abstract Hyponatremia is the most common electrolyte imbalance. It is associated with increased morbidity and in-hospital mortality. An effective early management is dependent on knowledge of epidemiology in the current population, accurate assessment of patient volume status and efficient diagnostic investigation. LÄS MER

  5. 4. A study of allergens in the mite Lepidoglyphus destructor, using monoclonal antibodies and recombinant techniques

    Författare :Susanna Olsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :allergen; characterization; dust mite; IgE-reactivity; monoclonal antibody; recombinant allergen; site-directed mutagenesis;

    Sammanfattning : Mites are one of the most common causes of allergic reactions in many parts of the world. They can broadly be divided into two categories: house dust mites, primarily found in dwellings, and storage mites, primarily found in farming environments and grain storage facilities. Storage mites have now also been shown to exist in house dust. LÄS MER
