  2. 1. On Efficient Transmission Balancing Operation : Capturing the Normal State Frequency and Active Power Dynamics

    Author : Martin Nilsson; Lennart Söder; Julia Matevosyan; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Power Dynamics; Frequency Control; Normal State; Power System Balancing; Transmission System Operator; Electrical Engineering; Elektro- och systemteknik;

    Abstract : In an electric power system, there will always be an electric balance. Nevertheless, System Operators (SOs) often uses the term imbalance. Here, the term imbalance refers to the difference between trades and real-time measurements. READ MORE

    Author : George Makau Nduva; Systemvirologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HIV-1; phylogenetics; risk groups; transmission dynamics;

    Abstract : With a national prevalence of 4.9% in the adult population, the HIV-1 epidemic in Kenya is the fifth largest in the world. READ MORE

  5. 3. Dynamics of Coinfection : Complexity and Implications

    Author : Samia Ghersheen; Vladimir Kozlov; Uno Wennergren; Vladimir Tkachev; Åke Brännström; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Living beings are always on risk from multiple infectious agents in individual or in groups. Though multiple pathogens' interactions have widely been studied in epidemiology. Despite being well known, the co-existence of these pathogens and their coinfection remained a mystery to be uncovered. READ MORE

  6. 4. Optimizing Enzyme Immobilization in Mesoporous Silica - A Spectroscopic Study of the Dynamics and Spatial Distribution of the Confined Enzymes

    Author : Pegah Sadat Nabavi Zadeh; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluorescence spectroscopy; dynamics; mesoporous silica; Immunogold staining; Transmission electron microscopy; anisotropy; microviscosity; real-time monitoring; Cy5.; Förster resonance energy transfer; Enzyme immobilization; Cy3;

    Abstract : Enzymes as biological catalysts are immobilized in porous materials to improve the enzyme activity and simplify their purification from the reaction media in biocatalytic applications. Mesoporous silica (MPS) particles are used as a promising support material for the immobilization of enzymes. READ MORE

  7. 5. Experimental Study on Truck Related Power Losses: The Churning Losses in a Transmission Model and Active Flow Control at an A-pillar of Generic Truck Cabin Model
