During the past century, Lake Takern and Lake Krankesjon, southern Sweden, have shifted repeatedly between a state of clear water and abundant submerged vegetation, and a state of turbid water and sparse vegetation. Long-term empirical data on such apparently alternative stable state dynamics are valuable as complements to modeling and experiments, although the causal mechanisms behind shifts are
OBJECTIVE: To analyze the extent of tumor necrosis factor-alpha (TNFalpha) and TNFbeta gene polymorphism in patients with AD and to relate it to intrathecal levels of these cytokines. METHODS: Analyses of TNFalpha and TNFbeta gene polymorphism were performed using PCR in 52 patients with AD and in 25 control subjects, and the levels of corresponding cytokines were analyzed using ELISA. RESULTS: Pa
Popular Abstract in Swedish Formstabilitet, dvs. förmågan för träet att behålla sin form, är en av de viktigaste parametrarna när trä används som byggnadsmaterial eller för andra ändamål. I allmänhet ändras träets dimensioner och form när dess fuktkvot ändras. Detta är dock inte önskvärt i konstruktioner, varför det behövs metoder som förbättrar formstabiliteten. I denna avhandling har inverkan aShape stability, the ability of the wood to retain its shape, is one of the most important parameters when using timber as a building material and for other applications. Generally, timber undergoes changes in dimensions and shape when its moisture content is changed. However, this can often not be tolerated in constructions and thus, methods to improve the shape stability have to be found. In th
The aim of this study was to study the relationship between physician-assessed quality of life parameters, i.e., toxicity and physical performance, and patients' self-reports of their quality of life (QoL). QoL was assessed at baseline and before each treatment. using the EORTC QLQ-C30. The WHO performance score (PS) and toxicity were assessed in physician interviews. The correlations between the
The relationships between, on the one hand, burnout, empathy and sense of cohoerence (SOC) and, on the other, personality traits were investigated, together with the effects of systematic clinical supervision on these phenomena among Swedish district nurses. The results in the supervisory group (n = 21) were compared with those of a comparison group (n = 12) in a quasi-experimental design. Persona
Popular Abstract in Swedish Avhandlingen handlar om lungornas funktion hos för tidigt födda (prematura) barn med brist på surfaktant, ett ämne som normalt ska finnas i lungorna, och hur lungfunktionen hos sådana barn kan förbättras genom tillförsel av det saknade ämnet utifrån. I avhandlingen har också använts en djurmodell (för tidigt födda lamm) för att studera hur konstgjord andning vid födelseThe thesis investigates lung function and the effects of rescue surfactant treatment in mechanically ventilated preterm human infants with respiratory distress syndrome (RDS), and the effects of ventilation at birth on the response to surfactant supplementation in preterm lambs. To assess lung function, the author recorded static pressure-volume (P-V) curves during passive deflation from total lun
The thesis concerns the development and application of two laser-based methods for combustion diagnostics: dual broadband rotational coherent anti-Stokes Raman spectroscopy (CARS) and laser-induced fluorescence (LIF). In efforts to increase the usefulness of the CARS technique, the applicability of a method involving a combination of the rotational CARS technique and the closely related vibration
The most malignant brain tumour, glioblastoma multiforme (GBM), has an utterly bad prognosis. In spite of all available therapy, the mean survival time is less than a year. In the unique BRIGTT project (Brain Immuno Gene Tumour Therapy), patients at the Dept of Neurosurgery. Lund University Hospital, are immunised with their own glioma cells, which have been transfected with the immunostimulatory
Canopy-held organic matter develops into a distinct soil system separate from the forest floor in wet temperate coniferous forests, creating a natural microcosm. We distinguished between fungal and bacterial components of the decomposer community in one site with Maple (Acer macrophyllum) and one site with Alder (Alnus rubra) by using direct measurements of growth; acetate incorporation into ergos
Identifying environmental factors that structure intraspecific genetic diversity is of interest for both habitat preservation and biodiversity conservation. Recent advances in statistical and geographical genetics make it possible to investigate how environmental factors affect geographic organisation and population structure of molecular genetic diversity within species. Here we present a study o
Cadmium is a non-essential toxic metal with multiple adverse health effects. Cadmium has been shown to be associated with cardiovascular diseases, but few studies have investigated heart failure (HF) and none of them reported atrial fibrillation (AF). We examined whether cadmium exposure is associated with incidence of HF or AF.
We studied bacterial and fungal colonization of submerged plant litter, using a known Si-accumulator (Equisetum arvense), in experimental microcosms during one month. We specifically addressed the microbial decomposer role concerning biogenic silica (bSiO2) dissolution from the degrading litter. To vary the rates and level of microbial colonization, the litter was combined with a range of mineral
We demonstrate a method that likely will improve the accuracy of functionals used in density functional theory and pair density functional theory. In deriving the method we show that the coupling-integrated exchange-correlation hole used in density functional theory obeys all the N-representability conditions as non-integrated holes and we give two such conditions, not normally used by the density
Synthesis and decomposition mechanisms of ternary Mg2FeH6 were investigated using in-situ synchrotron radiation powder X-ray diffraction (SR-PXD) and high-pressure differential scanning calorimetry (HP-DSC). Two routes for synthesis of Mg2FeH6 were studied. The first utilizes a ball-milled homogeneous MgH2-Fe powder mixture and the second uses a mixture of Fe and Mg formed by decomposition of the
This report is the outcome of Part I of a research project entitled An EPR system and new business models to in- crease reuse and recycling of textiles in the Nordic region. The overall aim of the project is to propose policy packages in Nordic countries which would support extended producer responsibility (EPR) systems and innovative business models which promote greater reuse and recycling of us
Rapeseed and tall oil are important renewable feedstocks for chemicals and energy — the former, an agricultural crop, and the latter, is a by-product of the pulp and paper industry. This report presents a study on the production of fatty epoxides from rapeseed methyl ester, tall oil methyl ester, and tall oil fatty acids by a solvent-free lipase-mediated process. Fatty epoxides are useful reactive
