  2. 1. Acute confusional state (delirium) : clinical studies in hip-fracture and stroke patients

    Author : Yngve Gustafson; Gösta Bucht; Bengt Winblad; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acute confusional state; delirium; elderly; stroke; femoral neck fractures; acetylcholine; cortisol;

    Abstract : Acute confusional state (ACS) or delirium according to DSM-III-R holds a central position in the medicine of old age. ACS is a common and sometimes the only symptom of diseases and medical complications in the elderly patient. READ MORE

  4. 2. Photosynthetic Oxygen Evolution - EPR studies of the manganese cluster of photosystem II

    Author : Sindra Peterson Årsköld; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; S2 state; second cycle; Biochemistry; Metabolism; Biokemi; metabolism; S0 state; light-adaptation; pulsed EPR; methanol; relaxation; microwave power saturation; S-cycle; Oxygen-evolving complex; Water-oxidizing complex;

    Abstract : In this thesis, a new electron paramagnetic resonance (EPR) signal from photosystem II is presented. The signal is shown to originate from the S0 oxidation state of the oxygen-evolving complex (OEC). READ MORE

  5. 3. Mammalian brain acetylcholinesterase : a study of its solubilization, purification, molecular state and interactions with cholinergic ligands including an endogenous modulator

    Author : Bertil Niklasson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Affinity chromatography; caudate nucleus; acetylcholinesterase; tetracaine; décaméthonium; d-tubocurarine; edrophonium; fluoride ion; hysteric properties; endogenous ligands to AChE;

    Abstract : Membrane bound AChE from calf brain caudate nucleus was solubilized by use of ion-free media in presence of 10~ M EDTA and 10“5M tetracaine. The irreversible release of AChE was more effectively inhibited by divalent ions compared to monovalent ions added to the medium. READ MORE

  6. 4. FLOW FIELD IN A HIGH HEAD FRANCIS TURBINE DRAFT TUBE DURING TRANSIENT OPERATIONS

    Author : Rahul Goyal; Michel J. Cervantes; Bhupendra K. Gandhi; Gabriel Ciocan; Lisa Prahl; Ramis Orlu; Gunilla Andree; Andrea Toffolo; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Francis turbine; Steady state; Transient; Particle Image Velocimetry; Vortex Rope; Strömningslära; Fluid Mechanics;

    Abstract : Hydroelectricity plays an important role to balance the stability of grid network.  In order to improve the stability of presently high loaded grids, hydropower plants are being operated over a wide range of operations and experiencing frequent start-stop, load rejection, and load acceptance.

  7. 5. The effect of solid state inclusions on the reactivity of UO2 : A kinetic and mechanistic study

    Author : Martin Trummer; Mats Jonsson; Lara Duro; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear chemistry; Kärnkemi;

    Abstract : The release of radionuclides is a key process in the safety assessment of a deep geological repository for spent nuclear fuel. A large fraction of the release is assumed to be a consequence of dissolution of the fuel matrix, UO2. In this doctoral thesis, the kinetics and the mechanisms behind oxidative U(IV) dissolution were studied. READ MORE
