We report absolute oscillator strengths for 119 Cr II transitions in the wavelength region 2050-4850 angstrom. The transition probabilities have been derived by combining radiative lifetimes, measured with time- resolved laser induced fluorescence, and branching fractions from intensity calibrated Fouirer transform spectrometer data. New radiative lifetimes for the 3d(4)(D-5)4p F-4, D-4 and P-6 te
Popular Abstract in Swedish Avhandlingens syfte är att beskriva, analysera och jämföra rekontextualiseringen av socialpedagogik i tre olika curriculum; I Nijmegen (Nederländerna), Lillehammer (Norge) och Sligo (Irland). Rekontextualisering, ett begrepp hämtat från Basil Bernstein, syftar på den transformation som sker när socialpedagogik flyttas in i ett undervisningssammanhang. Materialet bestårThe purpose of this thesis is to describe, analyse, and compare the recontextualisation of social pedagogy in three different curricula; in Nijmegen (NL), Lillehammer (N), and Sligo (IRL). The curricula represent different academic orientations and are located in different social-political contexts. The recontextualisation of social pedagogy, the concept derived from the works of Basil Bernstein,
In this paper, we present a new way to control linear stochastic systems. The method is based on statistical bootstrap techniques. The optimal future control signal is derived in such a way that unknown noise distribution and uncertainties in parameter estimates are taken into account. This is achieved by resampling from existing data when calculating statistical distributions of future process va

Summer N-2-fixing cyanobacterial blooms are a common feature in the Baltic Sea, and the occurrence of Nodularia spumigena toxic blooms is of particular concern. Cyanobacterial blooms can be favoured by certain conditions including high concentrations of dissolved organic matter, which may increase the availability of iron critical for N-2 fixation. Cyanobacteria may negatively affect grazers becau
We perform nuclear ground-state pairing calculations with the monopole pairing interaction. The particle number fluctuations are taken into account by the particle number projection method, with variation after projection. The pairing-correction energies obtained in this approach are compared to the BCS-model results. We discuss extensively how to properly incorporate different pairing models in g
Popular Abstract in Swedish Denna avhandling handlar till stora delar om fotodynamisk tumörterapi (PDT). PDT har sedan början av förra århundradet undersökts som ett tänkbart alternativ till strålningsbehandling, kirurgi och kemoterapi för behandling av cancertumörer i kroppen. Precis som namnet antyder involverar metoden en fotodynamisk reaktion. För att denna reaktion skall ske behövs tre kompoPhotodynamic therapy (PDT) as a cancer treatment modality relies on the simultaneous presence of three components; light, photosensitiser and oxygen. Once excited by the light, the photosensitiser can interact with oxygen, leading to the formation of toxic oxygen species. These reactive substances induce cellular damage within the irradiated tissue volume. PDT has been investigated for treating ma
The possibility of apparently negative causation has been discussed in a number of recent works on causation, but the discussion has suffered from being scattered. In this paper, the problem of apparently negative causation and its attempted solutions are examined in more detail. I discuss and discard three attempts that have been suggested in the literature. My conclusion is negative: Negative ca
Previous studies have suggested that the frequency of chromosomal aberrations (CAs), but not of sister chromatid exchanges (SCEs), predicts cancer risk. We have further examined this relationship in European cohorts comprising altogether almost 22,000 subjects, in the framework of a European collaborative project (CancerRiskBiomarkers). The present paper gives an overview of some of the results of
Efficient upconversion luminescence is observed from CdTe nanoparticles in solution and precipitated as solids. In the solids, the upconversion luminescence spectrum is significantly red shifted relative to the photoluminescence spectrum, whereas in solution, there is very little spectral shift. The upconversion luminescence exhibits a near-quadratic laser power dependence, both at room temperatur

Murine experimental autoimmune encephalomyelitis (EAE) is a commonly used model in the investigation of the human disease multiple sclerosis (MS), a debilitating inflammatory disease of the central nervous system (CNS). MS and EAE involve multiple steps, primarily, auto-antigenic leukocyte (mainly T-cells and macrophages) crossing the blood-brain barrier and later their invasion into the CNS where
The epidemiology and costs of repair and rehabilitation of zone 11 flexor tendon injuries in 135 patients from the southern part of Sweden were analysed. The little finger was most frequently injured (43%), usually with a knife (46%), and 30% of the injuries were work related. Total median costs within the health-care sector for the injuries were SEK 48,500 (1 EURO = 9.23 SEK, 4/1/2002). Costs in
This summary aims to highlight major results and insights gained from recent studies of hadronic final states in ep, p (p) over bar, e(+)e(-), as well as relevant theoretical developments, presented in the Multi-Hadron Final States parallel sessions of the DIS2002 workshop held in Krakow, Poland in May 2002.
Methods of avoiding common problems associated with operator work in automated process control, such as understimulation and difficulties in achieving and maintaining necessary skills and competence, are addressed in this paper. The source of these problems is deduced here to be that monitoring tasks are a predominant part of the job. This case study shows how work in a highly automated process ca
Cross-sectional studies have associated obesity and other components of the so-called metabolic syndrome with low-grade inflammation. The temporal and causal relations of this association have not been fully explored. This study explored whether elevated levels of inflammation-sensitive plasma proteins (ISPs) (fibrinogen, orosomucoid, {alpha}1-antitrypsin, haptoglobin, and ceruloplasmin) are assoc
