  1. 1. Turbulent premixed flames in a model gas turbine combustor: fuel sensitivity and flame dynamics

    Författare :Francesco Pignatelli; Strömningsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel flexibility; Premixed turbulent combustion; DNS; Optical diagnostic;

    Sammanfattning : The demand for energy security and reduction of greenhouse gas emissions has led to a surge of interest in the development of high-efficiency and low-emission gas turbine engines that can run on alternative low carbon content fuels, such as hydrogen-enriched fuel and syngas. However, the combustion characteristics of these fuels can significantly alter the flame characteristics and operability range of existing combustors. LÄS MER

  3. 2. Antidepressive and antipsychotic treatments : effects on nerve growth factor and brain-derived neurotrophic factor in rat brain

    Författare :Francesco Angelucci; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Recently it has been reported that depression and schizophrenia, the two major psychiatric disorders, are characterized by loss of neurons in specific brain regions. Nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) are proteins involved in neuronal survival and plasticity of dopaminergic, cholinergic and serotonergic neurons in the central nervous system (CNS).

  4. 3. New Approaches to Large-Scale Electronic Structure Calculations

    Författare :Francesco Aquilante; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Theoretical chemistry; orbital localization; electron correlation; analytic gradients; Cholesky decomposition; density fitting; quantum chemistry; Teoretisk kemi; kvantkemi;

    Sammanfattning : Recent years have witnessed a growing interest of the scientific community for the use of ab initio and density functional theory methods in theoretical studies of molecules containing many atoms. However, the `scaling wall' of some of the most accurate of such methods is often an obstacle for their applicability to systems of real-life interest, e. LÄS MER

  5. 4. Endogenous and treatment-induced neuroplasticity in mouse models of Parkinson's disease

    Författare :Francesco Bez; Basala gangliernas patofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Parkinson´s disease (PD) is an age-related neurodegenerative disorder characterized by a loss of nigral dopamine (DA) neurons that project their axons to the striatum. Striatal DA depletion causes the typical motor symptoms of PD. LÄS MER
