The European spallation source and future opportunities for materials science
The European Spallation Source is Europe's next generation high-power neutron source utilising a linear accelerator and a rotating tungsten target to produce neutrons that will be used for fundamental research and industrial applications. The facility is co-hosted by the states of Denmark and Sweden, and while the main site will be placed in Lund, Sweden, the Data Management and Software Centre wi
Medborgarskapande på olika villkor : Självbilder, skolkoder och syn på kunskap i den svenska gymnasieskolan
Citizens are not born, they are made. Based on fieldwork in two upper-secondary school classes in Sweden – an Introductory Programme class and a Social Science Programme class – this dissertation focuses on how pupils form their identities as citizens in a democratic society. Citizens are made in interaction with the society they inhabit, an interaction where power is always present. Although Swed
Process contributions of Australian ecosystems to interannual variations in the carbon cycle
New evidence is emerging that semi-arid ecosystems dominate interannual variability (IAV) of the global carbon cycle, largely via fluctuating water availability associated with El Niño/Southern Oscillation. Recent evidence from global terrestrial biosphere modelling and satellite-based inversion of atmospheric CO2 point to a large role of Australian ecosystems in global carbon cycle variability, i
Like being covered in a wet and dark blanket – Parents' lived experiences of losing a child to cancer
Purpose The aim of this study was to illuminate parents' lived experiences of losing a child to cancer. Method Interviews and a narrative about parents' experiences of losing a child to cancer were gathered from six parents of children whom had participated in a longitudinal study across the child's illness trajectory. The analysis of the data was inspired by van Manen's hermeneutic phenomenologic

Spatial and temporal variations of base cation release from chemical weathering on a hillslope scale
Cation release rates to catchment runoff from chemical weathering were assessed using an integrated catchment model that included the soil's unsaturated, saturated and riparian zones. In-situ mineral dissolution rates were calculated in these zones as a function of pH, aluminum and dissolved organic carbon (DOC) concentrations along a hillslope in Northern Sweden where soil water was monitored ove
Scintillate : An open-source graphical viewer for time-series calcium imaging evaluation and pre-processing
Background Calcium imaging is based on the detection of minute signal changes in an image time-series encompassing pre- and post-stimuli. Depending on the function of the elicited response, change may be pronounced, as in the case of a genetically encoded calcium-reporter protein, or subtle, as is the case in a bath-applied dye system. Large datasets are thus often acquired and appraised only duri
Leadership challenges of strategic research centres in relation to degree of institutionalisation
The purpose of this study was to describe and analyse leadership challenges in the organisation of strategic research centres, focusing on the relationship between organisation and the level of institutionalisation. Four main themes of leadership challenges were identified: (1) the changing university context, including relationships with top management and faculties; (2) research strategy, consid
A silicon depleted North Atlantic since the Palaeogene : Evidence from sponge and radiolarian silicon isotopes
Despite being one of Earth's major geochemical cycles, the evolution of the silicon cycle has received little attention and changes in oceanic dissolved silica (DSi) concentration through geologic time remain poorly constrained. Silicon isotope ratios (expressed as δ30Si) in marine microfossils are becoming increasingly recognised for their ability to provide insight into silicon cycling. In parti
CO2, δo2/N2 and APO: Observations from the Lutjewad, Mace Head and F3 platform flask sampling network
We report results from our atmospheric flask sampling network for three European sites: Lutjewad in the Netherlands, Mace Head in Ireland and the North Sea F3 platform. The air samples from these stations are analyzed for their CO2 and O2 concentrations. In this paper we present the CO2 and O2 data series from these sites between 1998 and 2009, as well as the atmospheric potential oxygen (APO). Th
Antifungal activities of extracts produced by liquid fermentations of Chilean Stereum species against Botrytis cinerea (grey mould agent)
Extracts obtained from liquid mycelial fermentations of Chilean species of the Stereum genus showed antifungal activity against Botrytis cinerea. Thirty-six strains were evaluated in vivo and in vitro assays, 25 belonging to Stereum hirsutum (Sh) and 11 to Stereum rameale (Sr). Two types of extracts were obtained: EtOAc-extract (liquid phase) and MeOH-extract (mycelial phase). Plate diffusion assa
Time-to-time correlation of high-risk atherosclerotic lesions identified with [(18)F]-FDG-PET/CT
OBJECTIVE: It has been shown that [(18)F]-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) can identify macrophage-rich high-risk atherosclerotic plaques in animal models as well as in patients with atherosclerotic plaques in the carotid arteries. The development of inflamed macrophage-rich plaques over time is not well known. This study was performed to determine t
A new high-resolution Holocene tephra stratigraphy in eastern Iceland : Improving the Icelandic and North Atlantic tephrochronology
A new and improved Holocene tephra stratigraphy and tephrochronological framework for eastern and northern Iceland is presented. Investigations of a sediment sequence from Lake Lögurinn have revealed a comprehensive tephra record spanning the last 10.200 years. A total of 157 tephra layers have been identified, whereof 149 tephra layers have been correlated to its source volcanic system using geoc

Methods Patients (n = 2174) recently diagnosed T2D (93%) or LADA (7%) were included upon arrival for their
ITPP treatment of RG2 glioblastoma in a rat model
Background: Inositol trispyrophosphate (ITPP) has been shown to reduce tumour growth in different animal cancer models, as well as of human U87 glioma cells grafted onto chick chorioallantoic membrane (CAM). The aim of this study was to establish whether ITPP crosses the blood-brain barrier and whether it halts the growth of RG2 glioblastoma tumour. Materials and Methods: A model comprising of Fis
Targeting of non-cycling cells of hypoxic tumors
Preserved leukocyte CD11b expression at the site of interstitial inflammation in patients with high-flux hemodiafiltration
The impact of high-flux hemodialysis on clinical outcomes remains controversial. We have previously shown that in vivo transmigrated leukocytes from patients with low-flux bioincompatible hemodialysis have an impaired capacity to upregulate CD11b at the site of interstitial inflammation. In the present study, we investigated the in vivo capacity of transmigrated monocytes and granulocytes to expre
An experiment on ascending evacuation on a long, stationary escalator
Ascending evacuation is becoming more relevant with underground stations reaching increasing depths. Therefore there is need for better understanding of the effects of physical exertion during evacuation. An experiment was conducted in a 61 m long, stationary escalator in Stockholm (Sweden) in order to obtain data on walking speeds, resting and behavior, which consisted on measuring the walking sp
