Soot particles can be formed in hydrocarbon flames as a result of an inefficient combustion process. The particles are near-spherical, and at later stages in the soot growth process, they form chainlike sparse aggregates. When applying optical diagnostic methods, this aggregation influences the evaluation of soot properties based on assumptions of isolated particles. In this paper an efficient and
New metastable massive particles with electric and colour charge are features of many theories beyond the Standard Model. A search is performed for long-lived gluino-based R-hadrons with the ATLAS detector at the LHC using a data sample corresponding to an integrated luminosity of 31 pb(-1). We search for evidence of particles that have come to rest in the ATLAS detector and decay at some later ti
BACKGROUND: Family members of persons with pre-dialysis chronic kidney disease may experience feelings of vulnerability and insecurity as the disease follows its course. Against this background, the aim of the present study was to explore empowerment in outpatient care as experienced by these family members. METHODS: An inductive approach for qualitative data analysis was chosen. The study sampl
This letter reports the results of a search for top and bottom squarks from gluino pair production in 4.7 fb(-1) of pp collisions at root s = 7 TeV using the ATLAS detector at the LHC. The search is performed in events with large missing transverse momentum and at least three jets identified as originating from a b-quark. Exclusion limits are presented for a variety of gluino-mediated models with
The aim of this study was to investigate associations between time use in daily activities and sociodemographic and clinical factors in order to identify individuals with persistent mental illness at risk of having an imbalance in daily activities, as reflected in their time use and daily rhythm. Participants (n=103) were selected from a psychiatric outpatient unit using a randomized stratified se
Musculoskeletal disorders (MSD) account for the majority of total morbidity cases in the working-age Swedish population. These disorders are thought to be the reason given for one-third of total certified sick leave requests. In addition to the high cost to society, MSD involve both physical and emotional suffering, pain and financial and social problems for the injured persons. The aim of this st
We present a search for a light (mass < 2 GeV) boson predicted by Hidden Valley supersymmetric models that decays into a final state consisting of collimated muons or electrons, denoted "lepton-jets". The analysis uses 5 fb(-1) of root s = 7 TeV proton-proton collision data recorded by the ATLAS detector at the Large Hadron Collider to search for the following signatures: single lepton-jets with a
Non-negative matrix factorization (NMF) condenses high-dimensional data into lower-dimensional models subject to the requirement that data can only be added, never subtracted. However, the NMF problem does not have a unique solution, creating a need for additional constraints (regularization constraints) to promote informative solutions. Regularized NMF problems are more complicated than conventio
This letter reports on a search for hypothetical heavy neutrinos, N, and right-handed gauge bosons, W-R, in events with high transverse momentum objects which include two reconstructed leptons and at least one hadronic jet. The results were obtained from data corresponding to an integrated luminosity of 2.1 fb(-1) collected in proton-proton collisions at root s = 7 TeV with the ATLAS detector at t
The purpose of this study was to investigate women's wishes and need for knowledge concerning sexuality and relationships in connection with gynecological cancer. A total of 11 women were interviewed following the completion of their treatment for gynecological cancer. The data was analyzed using latent content analysis. Two main categories were identified: "The absence of knowledge about the body
Fisher 344 rats with implanted N29 glioma tumours were treated with Pulsed Electric Fields (PEF) in combination with immunization using either IFN-gamma-gene-transfected syngeneic tumour cells or IFN-gamma transfected N29 cells treated with 10 micro-M 5-aza-2-deoxycytidine (DAC). Tumours (N29) were inoculated subcutaneously on both thighs of female F- 344 syngeneic rats. The left tumour was treate
The financial crisis in 2008 enlightened several shortcomings in the performance of the banking sector. As a result of this a more rigid regulatory framework, Basel III, has been developed which raises the requirements of banks’ capital and liquidity structure and internal capital adequacy processes. This involves evaluating potential future risks related to the strategy and risk appetite of a ban
Limits are set on the pair production of scalar leptoquarks, where all possible decays of the leptoquark into a quark (t, b) and a lepton (τ, ν) of the third generation are considered. The limits are presented as a function of the leptoquark mass and the branching ratio into charged leptons for up-type (LQ3 u → tν/bτ) and down-type (LQ3 d → bν/tτ) leptoquarks. Many results are reinterpretations of
In contrast with human hemoglobin (Hb) in red blood cells, plant Hbs do not transport oxygen, instead research points towards nitrogen metabolism. Using comprehensive and integrated biophysical methods we characterized three sugar beet Hbs: BvHb1.1, BvHb1.2 and BvHb2. Their affinities for oxygen, CO, and hexacoordination were determined. Their role in nitrogen metabolism was studied by assessing t
Background: Carpal tunnel syndrome (CTS) is a common cause of pain, weakness, sensory loss, and activity limitations. Currently, the most common initial treatment is use of a rigid splint immobilizing the wrist, usually during night-Time, for several weeks. Evidence regarding the efficacy and effect durability of wrist splinting is weak. The treatment is associated with costs and may cause discomf
Purpose: The purpose of this study was to investigate what treatment methods physiotherapists in Sweden use for infants 0–24 months hospitalised with acute breathing difficulties due to lower respiratory tract infections. Material and methods: We constructed an anonymous digital survey for paediatric physiotherapists in Sweden. It was distributed by e-mail and was posted on professional websites.
