Aim: Primary tumours in the central nervous system (CNS) are the second most common malignancy in childhood after leukaemia. Sweden has a high incidence and a high-survival rate in international comparative studies. This has raised the question about the type of tumours included in the Swedish Cancer registry. We therefore compared international data to the Swedish Childhood Cancer registry. Metho

Stat och kommun träffade 2010 en grundöverenskommelse om att införa en evidensbaserad praktik inom socialtjänsten. Sedan dess har överenskommelsen preciserats, en process som analyseras i denna artikel. Som vi kommer att visa återstår betydande oklarheter som det sociala arbetets aktörer behöver klargöra via förhandlingar. Detta är ett numera vanligt sätt att söka implementera politik och vi disku

Due to its four decades of high long-term economic growth and democratic system, Botswana has been depicted as an exceptional success story in a region full of economic and political failures. In this article,,a structural analysis is applied, and it is argued that Botswana's success should be understood as one of pre-modern growth without development. It is claimed that although the country may b

A series of QM/MM optimizations of the full protein of [Fe] hydrogenase were performed. The FeGP cofactor has been optimized in the water-bound resting state (1), with a side-on bound dihydrogen (2), or as a hydride intermediate (3). For inclusion of H4MPT in the closed structure, advanced multiscale modeling appears to be necessary, especially to obtain reliable distances between CH-H4MPT+ and th

Background: Zinc deficiency is a significant problem, in developing countries and in vegetarians, which can be caused by plant-based diets. Thus, dietary strategies, such as fermentation, to improve zinc bioavailability of diets should be investigated. Objective: To improve zinc bioavailability in a plant-based diet by the inclusion of fermented food. Design: Cassava tubers were fermented and made

The measurement of radioactive solutions containing organic or aggressive media may cause stability problems in liquid and plastic scintillation (PS) techniques. In the case of PS, this can be overcome by adding a crosslinker to the polymer structure. The objectives of this study are to synthesise a suitable crosslinked plastic scintillator (C-PS) for radioactivity determination in organic and agg

A multi-cell He gas scintillator active target, designed for the measurement of photoreaction cross sections, is described. The target has four main chambers, giving an overall thickness of 0.103 g/cm(3) at an operating pressure of 2MPa. Scintillations are read out by photomultiplier tubes and the addition of small amounts of N-2 to the He, to shift the scintillation emission from UV to visible, i

Hemolytic uremic syndrome (HUS) is a clinical syndrome characterized by microangiopathic hemolytic anemia, thrombocytopenia and acute renal failure. There are two subtypes: typical HUS associated with enterohemorrhagic E. coli (EHEC) and atypical HUS associated with uninhibited activation of the alternative pathway of complement. EHEC produce virulence factors such as lipopolysaccharide (LPS) and

Chemotherapy treatment usually involves the delivery of fluorouracil (5-Fu) together with other drugs through central venous catheters. Catheters and their connectors are increasingly treated with silver or argentic alloys/compounds. Complications arising from broken catheters are common, leading to additional suffering for patients and increased medical costs. Here, we uncover a likely cause of s

The Swedish Association for Applied Linguistics, ASLA (Association suédoise de linguistique appliquée) was formally founded as an autonomous Swedish affiliate of AILA in 1966. The constituting meeting was held at Lund University on April 12, 1966 during which the first chairperson, Professor Bertil Malmberg, was elected. This means that ASLA will be celebrating its 50th anniversary in 2016. Howeve

An observation of the Lambda(0)(b) -> Psi (2S) Lambda(0) decay and a comparison of its branching fraction with that of the Lambda(0)(b) -> Psi (2S) Lambda(0) decay has been made with the ATLAS detector in proton-proton collisions at root s = 8 TeVat the LHC using an integrated luminosity of 20.6fb(-1). The J/Psi and Psi(2S) mesons are reconstructed in their decays to a muon pair, while the Lambda(

Pair correlations between large transverse momentum neutral pion triggers (p(T) = 4-7 GeV/c) and charged hadron partners (p(T) = 3-7 GeV/c) in central (0%-20%) and midcentral (20%-60%) Au + Au collisions at root s(NN) = 200 GeV are presented as a function of trigger orientation with respect to the reaction plane. The particles are at larger momentum than where jet shape modifications have been obs

The question of how diverging populations become separate species by restraining gene flow is a central issue in evolutionary biology. Assortative mating might emerge early during adaptive divergence, but the role of other types of reproductive barriers such as migration modification have recently received increased attention. We demonstrate that two recently diverged ecotypes of a freshwater isop

A search for second and third generation scalar and vector leptoquarks produced in ep collisions via the lepton flavour violating processes ep -> mu X and ep -> tau X is performed by the H1 experiment at HERA. The full data sample taken at a centre-of-mass energy root s = 319 GeV is used for the analysis, corresponding to an integrated luminosity of 245 pb(-1) of e(+)p and 166 pb(-1) of e(-)p coll
