Background: Changes in the autonomic nervous system (ANS) tone are present before, during, and after episodes of atrial fibrillation (AF). Atrial fibrillatory rate (AFR, the inverse of the atrial cycle length) has been used as a surrogate marker for local refractoriness and is a key characteristic of the fibrillatory process in patients with AF. Aim of this study is to assess changes in AFR, as an
From the 6th to the 9th of November 2016, in the meeting hall of Centro Nacional de Aceleradores(University of Seville, Seville, Spain) took place the “II International Conference onRadioecological Concentration Processes (50 years later)” under the joint organization of theUniversities of Seville (Spain) and Gothenburg (Sweden). With this event, the organization try tocommemorate the fifty years
All cities face a pressing challenge - how can they provide economic prosperity and social cohesion while achieving environmental sustainability? In response, new collaborations are emerging in the form of urban living labs - sites devised to design, test and learn from social and technical innovation in real time. The aim of this volume is to examine, inform and advance the governance of sustaina
Entomological radars employing the 'ZLC' (zenith-pointing linear-polarized narrow-angle conical scan) configuration detect individual insects flying overhead and can retrieve information about a target's trajectory (its direction and speed), the insect's body alignment and four parameters that characterize the target itself: its radar cross section, two shape parameters and its wingbeat frequency.
The determination of reversible phase transitions in the perovskite-type thermoelectric oxide Eu0.8Ca0.2TiO3–δ is fundamental, since structural changes largely affect the thermal and electrical transport properties. The phase transitions were characterized by heat capacity measurements, Rietveld refinements, and pair distribution function (PDF) analysis of the diffraction data to achieve informati
The current ambition to enlarge the European Union (EU) from fifteen to twenty-seven member states has brought to the fore questions about European integration and its overarching aim. On 7 June, 2001, the Irish people decided not to ratify the Nice Treaty. However, the Irish 'no' was not considered to be an expression of political resentment that could impinge on further development of European i
Studiens syfte var att undersöka kvinnors erfarenhet av depression och sätta in dem i en samtida kontext. Semistrukturerade intervjuer genomfördes med åtta kvinnliga deltagare med erfarenhet av depression. Intervjumaterialet analyserades med tematisk analys och åtta olika teman identifierades. Till studiens resultat hör att deltagarna beskrev depression ur flera olika perspektiv och använde delvisThe purpose of this study was to look into women’s experiences of depression and to put them in a contemporary context. Semi-structured interviews were conducted with eight female participants having experienced depression. The data was analyzed by using thematic analysis, which enabled the identification of eight different themes. Results shows that participants described depression from several
Batterier möjliggör mer solel än elnätet tidigare klarat av En ökad andel solenergi i elnätet ställer nya tuffa krav på det befintliga nätet. I det här examensarbetet har möjligheten att undvika nätförstärkning genom att istället installera batterier på väl valda platser i nätet undersökts. Med hjälp av lösningen kan mer solel än nätet tidigare klarat av installeras. Historiskt sett har el produThis thesis addresses overvoltage issues in weak low voltage grids caused by large solar power production. The suggested method is using PI controllers to control voltage. This is done by using battery energy storage systems (BESS), designed to absorb active power during these times and thereby limiting the voltage rise. This could enable faster integration of solar power and a reduced demand for
Questions: (1) Does soil acidification in calcareous sandy grasslands lead to loss of plant diversity? (2) What is the relationship between the soil content of lime and the plant availability of mineral nitrogen (N) and phosphorus (P) in sandy grasslands? Location: Sandy glaciofluvial deposits in south-eastern Sweden covered by xeric sand calcareous grasslands (EU habitat directive 6120). Methods:
Pyrene chromophores carrying different rigid rod spacer groups (ethynylene, ethynylene-phenylene-ethynylene, and ethynylene-bicyclo[2.2.2]octylene-ethynylene) and bound to TiO2 nanostructured materials via an isophthalic acid (Ipa) anchor group have been investigated using quantum chemical calculations in order to elucidate structural and electronic properties of dye-sensitized semiconductor struc
OBJECTIVE: Periodontal ligament (PDL) cells express oestrogen receptor beta (ERbeta) protein, but cellular functions regulated by ERbeta in these cells have not been identified. In this study we determine if ERbeta is localised to mitochondria and if oestrogen regulates mitochondrial function in human PDL cells obtained from teeth extracted for orthodontic reasons. DESIGN: Subcellular distribution
Giant cell tumor of bone (GCTB) is a benign but locally aggressive tumor with metastatic potential. We performed cytogenetic analysis on 10 1 GCTB from 92 patients. Karyotypes were obtained from 95 tumors, 47 of which had clonal aberrations. The majority of the cytogenetically abnormal GCTB had multiple, up to 28 per tumor, clones. Clonal telomeric associations (tas) and other structural and numer
Aims/hypothesis: Mutations in hepatic nuclear factor 1alpha cause a monogenic form of diabetes, maturity onset diabetes of the young type 3 (MODY3). Our aim was 1) to assess the uptake of genetic testing for MODY3 and to determine factors affecting it, and ( 2) to compare attitudes to predictive genetic testing between families with MODY3 and a previously studied group at risk of hereditary nonpol
Inflammatory challenges of the airway mucosa cause luminal entry of bulk plasma. Extravasation of plasma is well described but the routes for epithelial passage of plasma are largely unknown. Using colloidal gold (5 nm) as tracer we have now examined the fate of extravasated plasma in the airways. The tracer was given intravenously to anaesthetized, ovalbumin-sensitized guinea-pigs 2min prior to a
Novel triblock copolymers based on central poly( ethylene glycol) ( PEG) or poly( ethylene glycol-co-propylene glycol) (PEGPG) blocks with poly( pentafluorostyrene) (PFS) outer blocks were prepared by Atom Transfer Radical Polymerization (ATRP) with polydispersities on the order of 1.2 - 1.3. The bromoisobutyrate functionalized polyether macroinitiators with molecular masses (M-n) of approx. 10 00
Water is an essential parameter for fungal degradation of wood, but degradation primarily occursat high moisture levels at water potential in the range of -4 to -0.1 MPa, which corresponds to 97-99.9% relative humidity. At these moisture levels, water is present in the wood structure both inand outside of cell walls. The majority of previous studies on the interaction between wood andwater for unt
Increased productivity is of societal good and efforts to achieve this should be a relevant task for all businesses. However, the concept of productivity is not clear as to what is to be measured. This becomes a problem especially when statements are made that the development of productivity in the construction industry is not as good as other sectors of industry. It is not clear if this compariso
The type of chemical reaction between hapten and carrier protein in the formation of a complete antigen in vivo giving rise to an allergic contact dermatitis (ACD, type IV allergy) is essentially unknown. About 4,000 low-molecular organic compounds are known to have allergenic properties. ,-Unsaturated carbonyl structures are frequently present among these compounds. Haptens giving rise to antibod
BACKGROUND: Degranulation of eosinophils in target tissues is considered a key pathogenic event in major chronic eosinophilic diseases. However, because of a lack of appropriate methods, little is known about degranulation of eosinophils in common eosinophilic diseases. METHODS: Using transmission electron microscopic (TEM) analysis, a novel approach has been devised and validated to quantify eosi
