A search has been performed for pair production of heavy vectorlike down-type (B) quarks. The analysis explores the lepton-plus-jets final state, characterized by events with one isolated charged lepton (electron or muon), significant missing transverse momentum, and multiple jets. One or more jets are required to be tagged as arising from b quarks, and at least one pair of jets must be tagged as
A search is reported for the pair production of a new quark b' with at least one b' decaying to a Z boson and a bottom quark. The data, corresponding to 2.0 fb(-1) of integrated luminosity, were collected from pp collisions at root s = 7 TeV with the ATLAS detector at the CERN Large Hadron Collider. Using events with a b-tagged jet and a Z boson reconstructed from opposite-charge electrons, the ma
The fecal microbiota of two healthy Swedish infants was monitored over time by terminal restriction fragment length polymorphism (T-RFLP) analysis of amplified 16S rRNA genes. Principal component analysis (PCA) of the T-RFLP profiles revealed that the fecal flora in both infants was quite stable during breast-feeding and a major change occurred after weaning. The two infants had different sets of
A search is presented for direct top squark pair production using events with at least two leptons including a same-flavour opposite-sign pair with invariant mass consistent with the boson mass, jets tagged as originating from -quarks and missing transverse momentum. The analysis is performed with proton-proton collision data at collected with the ATLAS detector at the LHC in 2012 corresponding to
Objective. New proposed definitions of chronic kidney disease necessitate the development and use of simple and accurate methods for estimating glomerular filtration rate (GFR). Plasma cystatin C has been shown to be a more reliable GFR marker than creatinine and formulae for estimating GFR have been reported. The purpose of this study was to validate a cystatin C-based GFR prediction equation in
Background. Randomized trials have shown that icodextrin reduces the volume of extra-cellular fluid (ECFv) with variable effects on residual renal function. To explore this fluid shift and its possible mechanisms in more detail, prospectively collected data from one such trial, including measures of inflammation (C-reactive protein, tumor necrosis factor-a, albumin and low and high molecular weigh
A search is presented for a narrow resonance decaying to a pair of Z bosons using data corresponding to 1.02 fb(-1) of integrated luminosity collected by the ATLAS experiment from pp collisions at root s= 7 TeV. Events containing either four charged leptons (llll) or two charged leptons and two jets (lljj) are analyzed and found to be consistent with the Standard Model background expectation. Lowe
The study field of the thesis is regional integration in Africa. The focus is set on the African Union (AU) and its main programme for promoting democracy on the continent, the New Partnership for Africa´s Development (NEPAD). By applying two theories, one on democratization through regional organizations and the other on hidden agendas within them, the thesis makes an assessment on the work for d
Aim: To investigate the effect of general anaesthesia on the TCI-dosage, the depth of anaesthesia and the need for hemodynamic treatment. A comparison between general anaesthesia (GA) alone and general anaesthesia combined with epidural anaesthesia (GA+EDA). Background: There are some uncertainties in the literature whether epidural anaesthesia has any effect on general anaesthesia governed by Ta
The thesis studies the situation within Lund University in relation to the implementation of the European Standards and Guidelines (ESG) developed by The European Association for Quality Assurance in Higher Education (ENQA). The aim of the study is to answer the following research question “How have Lund University implemented the European Standards and Guidelines developed by The European Associa
Nuvarande reglering av säkerhet i lös egendom i Sverige bygger, med undantag för några lagstiftningsåtgärder, på rättspraxis och juridisk doktrin. Även om pantsättning är huvudmetoden för att ställa säkerhet, används i praktiken flera olika typer av säkerhetsrätter då lagstiftaren infört separata registersystem (t.ex. företagshypotek) och då äganderätt i praktiken ofta används som säkerhet (t.ex. Present Swedish law concerning security over movable assets is largely based on case law and legal literature, with some statutory intervention. Although the principal form of security is the possessory pledge, various security devices are used in practice, pursuant to legislative introductions of separate registration systems (e.g. floating charges) and the commercial use of ownership for securit
The aim of this phenomenological study was to explore what role teachers at introductory programmes (SFI-schools) play in the integration of immigrants, how the teachers experience their work and what they feel about the situation in which their students, the immigrants, are. To what extent and in what way do the teachers contribute to facilitating the integration of the immigrant students? The s
Objective: To assess the relative validity of two diet assessment methods, an extensive quantitative food frequency questionnaire (method A) and a novel shorter quantitative food frequency questionnaire with a 14 day food record (method B). Design: A randomized prospective cohort study. Setting: General community. Subjects: 206 residents of the town of Malmö, aged between 50-69 years, 101 men and
Eight different generations of dolerite dykes crosscutting the Paleoproterozoic basement in West Africa and one in South America were dated using the high precision U–Pb TIMS method on baddeleyite. Some of the individual dykes reach over 300Â km in length and they are considered parts of much larger systems of mafic dyke swarms representing the plumbing systems for large igneous provinces (LIPs).
Background Human leukocyte antigen (HLA) matching isn't routinely performed in heart transplantation. Novel allograft perfusion methods may make HLA matching feasible. The purpose of this study is to reexamine whether HLA mismatch may be used in risk stratification to improve outcomes in heart transplantation. Methods and Results We analyzed 34 681 recipients undergoing heart transplantation betwe
Class Ib ribonucleotide reductases (RNR) utilize a di-nuclear manganese or iron cofactor for reduction of superoxide or molecular oxygen, respectively. This generates a stable tyrosyl radical (Y·) in the R2 subunit (NrdF), which is further used for ribonucleotide reduction in the R1 subunit of RNR. Here, we report high-resolution crystal structures of Bacillus anthracis NrdF in the metal-free form
Objectives This study aimed to investigate the importance of potentially inappropriate medications, number of medications and chronic conditions for the risk of hospitalisation among an elderly population. Design This is a case-control study. Setting Population-based study in 2013 of all individuals aged 75 years and older (17 203) in the county of Blekinge in the southeast of Sweden. Participants
Introduction Fever is an integral part of the inflammatory response and has therefore likely a physiological role in fighting infections. Nevertheless, whether fever in itself is beneficial or harmful in adults is unknown. This protocol for a systematic review aims at identifying the beneficial and harmful effects of fever control interventions in adults. Methods and analysis This protocol for a s
