We present the results of a search for new, heavy particles that decay at a significant distance from their production point into a final state containing charged hadrons in association with a high-momentum muon. The search is conducted in a pp-collision data sample with a center-of-mass energy of 7 TeV and an integrated luminosity of 33 pb(-1) collected in 2010 by the ATLAS detector operating at
The overall aim of thesis was to explore frail older people’s experiences of receiving healthcare and/or social services and to investigate healthcare consumption and costs in both men and women and in different age groups in the two years prior to the introduction of long-term municipal care. A second aim was to explore a preventive intervention in a pilot study using case managers to older peopl

The aim was to investigate whole-body and red marrow absorbed doses in treatments of neuroblastoma (NB) and adult neuroendocrine tumors (NETs) with (131)I-metaiodobenzylguanidine and to propose a simple method for determining the activity to administer when dosimetric data for the individual patient are not available.
This Letter presents a search for contact interactions in the dielectron and dimuon channels using data from proton-proton collisions produced by the LHC at,root s = 7 TeV and recorded by the ATLAS detector. The data sample, collected in 2011, corresponds to an integrated luminosity of 1.08 and 1.21 fb(-1) in the e(+)e(-) and mu(+)mu(-) channels, respectively. No significant deviations from the st
Using data recorded in 2011 with the ATLAS detector at the Large Hadron Collider, a search for evidence of extra spatial dimensions has been performed through an analysis of the diphoton final state. The analysis uses data corresponding to an integrated luminosity of 2.12 fb(-1) of root s = 7 TeV proton-proton collisions. The diphoton invariant mass (m(gamma gamma)) spectrum is observed to be in g
New basis sets of the atomic natural orbital (ANO) type have been developed for the lanthanide atoms La-Lu. The ANOs have been obtained from the average density matrix of the ground and lowest excited states of the atom, the positive ions, and the atom in an electric field. Scalar relativistic effects are included through the use of a Douglas-Kroll-Hess Hamiltonian. Multiconfigurational wave funct
This dissertation looks into the treatment of exposed children and young people. The background is a puzzlement as to how the discourse on treatment, during the latest twenty years, has concentrated on the same institutions and themes (Ebsen, 2007). The aim of the dissertation is to shed light on how the institutions of child saving, (family care, placement in residential care, intervention in the
Spectroscopic Photoemission and Low Energy Electron Microscopy (SPELEEM) is a very powerful and diverse microscopy technique for the investigation of surfaces, interfaces, buried layers and nanoscale objects like nanoparticles and nanowires. The many significant results from photoemission Electron microscopy (PEEM) in recent years are linked with the exploitation of advanced light sources such as
Background: Irritable bowel syndrome (IBS) and gastrointestinal (GI) dysmotility disorders have a similar clinical picture, although dysmotility disorders require the attention of a specialist. Patients with primary Sjogren's syndrome (pSS) have also been described to suffer from IBS-like symptoms. No objective marker is available to distinguish between the patients. A visual analogue scale has be
BACKGROUND-Multiple laboratory tests are used in the diagnosis and management of patients with diabetes mellitus. The quality of the scientific evidence supporting the use of these assays varies substantially. APPROACH-An expert committee compiled evidence-based recommendations for the use of laboratory analysis in patients with diabetes. A new system was developed to grade the overall quality of
Background: Total hip joint replacement (THR) is a high volume, effective intervention for hip osteoarthritis (OA). However, indications and determinants of outcome remain unclear. The 'EUROHIP consortium' has undertaken a cohort study to investigate these questions. This paper describes the variations in disease severity in this cohort and the relationships between clinical and radiographic sever
Stretch of vascular smooth muscle stimulates growth and proliferation as well as contraction and expression of contractile/cytoskeletal proteins, all of which are also regulated by calcium-dependent signals. We studied the role of the calcium- and integrin-activated proline-rich tyrosine kinase 2 (PYK2) in stretch-induced responses of the rat portal vein loaded by a hanging weight ex vivo. PYK2 ph
I artikeln presenteras ett projekt om forskares behov av stöd, genomfört 2012, inom biblioteksnätverket Lunds universitets bibliotek (LUB). Projektet består av a) en litteraturöversikt med fokus på definitioner av och exempel på forskarstöd samt vilka behov och erfarenheter forskare själva har av forskarstöd, b) en enkätundersökning av befintlig forskarservice från biblioteken inom (LUB), ett deceThis article presents a 2012 project on researchers’ need of support at Lund University Libraries (LUB). The project was three folded with the object to identify areas where the present research support services ought to be developed and strengthened. The project contains a) a literature review focusing on definitions and examples of research support services as well as researchers’ needs and expe
M1 aminopeptidases comprise a large family of biologically important zinc enzymes. We show that peptide turnover by the M1 prototype, leukotriene A4 hydrolase/aminopeptidase, involves a shift in substrate position associated with exchange of zinc coordinating groups, while maintaining the overall coordination geometry. The transition state is stabilized by residues conserved among M1 members and i
The main missions of the EuPA Education Committee (EuPA-EC) are to promote and enhance the quality of proteomics knowledge by creating educational programs and to initiate European-wide scientific exchange programs for young proteomics researchers. In this first report we present the initial actions we have undertaken in relation to the missions of the EuPA-EC, and the educational activities that
Children with acute lymphoblastic leukemia (ALL) have been shown to develop changes on computed tomography (CT) scans of the brain. These changes are seen both during and after therapy. Some of the results have been contradictory. Nine children with ALL were examined by CT of the brain during induction therapy. All children showed normal CT scans on the day of diagnosis. One month later all had di
