  1. 21. District Heating for Residential Areas with Single-Family Housing -with Special Emphasis on Domestic Hot Water Comfort

    Författare :Tommy Persson; Energihushållning; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low heat density; District heating; single-family housing; domestic hot water comfort; domestic hot water control; heat losses; supply temperature; thermostatic valves; Energiforskning; Energy research; marketing strategies; market penetration;

    Sammanfattning : The concept of district heating (DH) involves centralised heat production where heat is distributed to consumers via a piping network. It is essential that benefits achieved from concentrated, large-scale production instead of local production in each building exceed the costs associated with heat distribution. LÄS MER

  3. 22. A structural study into the boundary surface and associated curvature of three-dimensional mesoporous silica crystals

    Författare :Keiichi Miyasaka; Osamu Terasaki; Reinhard Nesper; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mesoporous crystal; electron crystallography; electrostatic potential map; equi-potential surface; curvature; multiplly-twinned particle; Chemistry; Kemi; Structural Chemistry; strukturkemi;

    Sammanfattning : Since their first discovery in the early 1990s, mesoporous crystals (MCs) have fascinated researchers in various fields because of their interesting structures and their potential uses. Electron crystallography (EC) gives the direct three-dimensional (3D) realization of a crystal as a reconstructed electrostatic potential map (EPM). LÄS MER

  4. 23. Experimental studies on novel pharmacological strategies in the treatment of schizophrenia

    Författare :Amani Eltayb; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Schizophrenia; L-dopa; topiramate; 5-HT2C; citalopram; WAY 100635; CAR; catalepsy;

    Sammanfattning : The modified dopamine (DA) hypothesis of schizophrenia suggests a hyperdopaminergic state in subcortical brain regions, which is believed to cause positive symptoms, while cortical regions may show a hypodopaminergic state which is believed to generate negative and cognitive symptoms. Positive symptoms are improved by typical antipsychotic drug (APD) treatment. LÄS MER

  5. 24. Surgical treatment of atrial fibrillation : clinical, hormonal and electrophysiological aspects of the maze operation

    Författare :Anders Albåge; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Atrial fibrillation (AF) is the most common arrhythmia, associated with significant mortality and morbidity, due to hemodynamic impairment and the increased risk of stroke. Traditional pharmacological treatment may be insufficient or cause intolerable side-effects. LÄS MER

  7. 25. Effects of antipsychotics on GABA neurons in the basal ganglia of the rat

    Författare :Jiang Yu; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; antipsychotics; γ-aminobutyric acid; glutamic acid decarboxylase; basal ganglia; entopeduncular nucleus; vacuous chewing movements; Neurovetenskap; Neurology; Neurologi; Psychiatry; psykiatri;

    Sammanfattning : Antipsychotics are used in the treatment of psychosis and, based on their propensities to induce extrapyramidal side effects (EPS), are divided into typical (haloperidol) and atypical (clozapine) subtypes. The incidence of EPS, arises from an imbalance in the neurotransmission between two majorGABAergic pathways of the basal ganglia that connect the striatum directly to the entopeduncular nucleus (EP) and the substantia nigra reticulata or indirectly via the globus pallidus and the subthalamic nucleus.
