A measurement of the mass difference between top and anti-top quarks is presented. In a 4.7 fb(-1) data sample of proton-proton collisions at root s = 7 TeV recorded with the ATLAS detector at the LHC, events consistent with t (t) over bar production and decay into a single charged lepton final state are reconstructed. For each event, the mass difference between the top and anti-top quark candidat

A method for CdSe quantum dot (QD) sensitization of ZnO nanowires (NW) with fast adsorption rate is applied. Photoinduced excited state dynamics of the quantum dots in the case of more than monolayer coverage of the nanowires is studied. Transient absorption kinetics reveals an excitation depopulation process of indirectly attached quantum dots with a lifetime of similar to 4 ns. Photoluminescence

The sulfation of KCl during biomass combustion has implications for operation and emissions: it reduces the rates of deposition and corrosion, it increases the formation of aerosols, and it leads to higher concentrations of HCl and lower concentrations of SO2 in the gas phase. Rigorously homogeneous systems are required to characterize the gas-phase formation of alkali sulfates. We have measured t

PURPOSE: To examine the impact of systematic medication reconciliations upon hospital admission and of a medication review while in hospital on the number of inappropriate medications and unscheduled drug-related hospital revisits in elderly patients. METHODS: This was a prospective, controlled study in 210 patients, aged 65 years or older, who were admitted to one of three internal medicine wards

The ability to measure and understand heat flow in nanowire composites is crucial for applications ranging from high-speed electronics to thermoelectrics. Here we demonstrate the measurement of the thermal conductance of nanowire composites consisting of regular arrays of InAs nanowires embedded in PMMA using time-domain thermoreflectance (TDTR). On the basis of a proposed model for heat flow in t

The early clinical trials using fetal ventral mesencephalic (VM) allografts in Parkinson's disease (PD) patients have shown efficacy (albeit not in all cases) and have paved the way for further development of cell replacement therapy strategies in PD. The preclinical work that led to these clinical trials used allografts of fetal VM tissue placed into 6-OHDA lesioned rats, while the patients recei

Migration to Next Generation Internet architectures poses new challenges for network operators in planning core networks and calls for efficient network planning and optimization tools. Optimization models underlying such tools are developed in this thesis. We study a number of single and two-layer core network design problems defined as mathematical programmes, focusing on fair bandwidth allocati

Cell-based therapies are emerging as new promising treatments in stroke. However, their functional mechanism and therapeutic potential during early infarct maturation has so far received little attention. Here, we asked if cell-based delivery of the interleukin-1 receptor antagonist (IL-1Ra), a known neuroprotectant in stroke, can promote neuroprotection, by modulating the detrimental inflammatory

Popular Abstract in Swedish För att ett transplanterat organ ska accepteras av mottagaren behövs immunhämmande läkemedel. Dessa läkemedel dämpar immunförsvaret och förhindrar avstötning av det transplanterade organet. Immunförsvaret har olika sätt att angripa organet, som det uppfattar som kropps-främmande. Idag används olika läkemedel i kombination som behandling mot avstötning. Tyvärr är dessa mTransplantation of vital organs is today a widely used treatment when failure of the organ is a fact. To prevent rejection immunosuppresive treatment must be maintained lifelong, unless transplantation is perfomed between identical twins. Many immunosuppresive agents introduced in clinical practice have been benificial in improving graft survival rates, but adverse effects remains a huge problem t

OBJECTIVE: The aim of this study was to design a trial that could evaluate the effect of acceptance and commitment therapy as a group-intervention for multiple sclerosis patients with psychological distress. DESIGN: Randomized controlled trial with assessment at pretreatment, end of treatment, and at 3-month follow-up. SUBJECTS: Multiple sclerosis outpatients with elevated symptoms of anxiety and/

When host species colonize new areas, the parasite assemblage infecting the hosts might change, with some parasite species being lost and others newly acquired. These changes would likely lead to novel selective forces on both host and its parasites. We investigated the avian blood parasites in the passerine bird community on the mid-Atlantic island of Sao Miguel, Azores, a bird community originat

Popular Abstract in Swedish Stroke är en sjukdom som främst drabbar äldre och är den största anledningen till att människor får olika slags handikapp såsom förlamning och afasi. Det finns ännu ingen effektiv behandling för att lindra symtom och lidande efter en stroke, förutom rehabilitering, och därför kostar stroke samhället enormt mycket pengar. Befolkningen blir allt äldre, vilket även medför Cell replacement by neural transplantation can, in animal models of neurodegenerative diseases, reconstruct damaged brain circuitry. In the clinical situation, the graft material used for cell therapy must, most likely, be of human origin. The human fetal brain is one potential source of neural stem cells (NSCs) for cell replacement therapy in neurodegenerative disorders such as stroke. Stroke is

Background: Massive sequencing of genes from different environments has evolved metagenomics as central to enhancing the understanding of the wide diversity of micro-organisms and their roles in driving ecological processes. Reduced cost and high throughput sequencing has made large-scale projects achievable to a wider group of researchers, though complete metagenome sequencing is still a daunting

Background: Intimate partner violence (IPV) during pregnancy is a serious matter which threatens maternal and fetal health. The aim of this study was to develop a grounded theoretical model of women's experience of IPV during pregnancy and how they handle their situation. Method: Ten interviews with women who had experience of being exposed to IPV during pregnancy were analyzed using the grounded
