    Sammanfattning : Monomethylmercury, MeHg, is formed under anoxic conditions in waters, sediments and soils and then bioaccumulated and biomagnified in aquatic food webs, negatively effecting both human and wildlife health. It is generally accepted that precipitation of mercury, Hg, and adsorption of Hg to e.g. LÄS MER

    Sammanfattning : Since 2008 advanced home healthcare agencies (ASiH) in a larger Swedish county council has underwent a transformation, to become part of a coming concept: networked healthcare (NVS). NVS means that intermediate multi-organizational healthcare (IMV) will be produced often in the home, and from 2013 to an increasing number of patients in different age groups with different diagnoses and medical conditions - in large variability of needs.

    Sammanfattning : There is a need for evaluation of new treatment modalities in depression. The aims of thisthesis were to investigate the effect of 2 hours of daily light treatment for 10 days in patientswith a major depression with seasonal or nonseasonal pattern and to study subgroups ofdepressed patients with respect to clinical, demographic, and neuroendocrine factors, theeffect of exposure to bright light, dexamethasone suppression test, CRH stimulation and thehormonal effect of light exposure on healthy controls.

    Sammanfattning : Magnetic metamaterials consisting of arrays of densely packed, two-dimensional nanoscale magnetic islands have degrees of freedom on two separate length scales: inside the islands, and among them. These degrees of freedom can be tuned by e.g. size, shape, island separation and lattice geometry. LÄS MER
