Observations of neutral-current nu interactions on deuterium in the Sudbury Neutrino Observatory are reported. Using the neutral current (NC), elastic scattering, and charged current reactions and assuming the standard 8B shape, the nu(e) component of the 8B solar flux is phis(e) = 1.76(+0.05)(-0.05)(stat)(+0.09)(-0.09)(syst) x 10(6) cm(-2) s(-1) for a(More)
The Sudbury Neutrino Observatory (SNO) has measured day and night solar neutrino energy spectra and rates. For charged current events, assuming an undistorted 8B spectrum, the night minus day rate is 14.0%+/-6.3%(+1.5%)(-1.4%) of the average rate. If the total flux of active neutrinos is additionally constrained to have no asymmetry, the nu(e) asymmetry is(More)
Results are reported from the complete salt phase of the Sudbury Neutrino Observatory experiment in which NaCl was dissolved in the D 2 O target. The addition of salt enhanced the signal from neutron capture, as compared to the pure D 2 O detector. By making a statistical separation of charged-current events from other types based on event-isotropy(More)
OBJECTIVE To examine the relationship of fatigue in people with rheumatoid arthritis (RA) with self-efficacy, positive and problematic aspects of social support, and demographic and disease-related variables. METHOD Out-patients with at least 5 yr RA were studied. Fatigue was measured with a visual analogue scale. Other variables included were: positive(More)
A search has been made for neutrinos from the hep reaction in the Sun and from the diffuse supernova neutrino background (DSNB) using data collected during the first operational phase of the Sudbury Neutrino Observatory, with an exposure of 0.65 ktons yr. For the hep neutrino search, two events are observed in the effective electron energy range of 14:3 MeV(More)
Several micro-organisms, especially viruses, have been associated with juvenile and adult onset Still's disease. In the present study a search for probable triggering viral infections in five consecutive patients with early, active adult onset Still's disease has been made. In one patient echovirus 7 was identified as a probable triggering agent. Evidence(More)
The clinical and laboratory features, treatment, prognosis, complications and disability of 45 patients with adult-onset Still's disease were studied. Sixty per cent of the patients were female. Median age at onset was 25 years and median observation period after onset was 41 months. For 28 patients detailed data were available of the first month of(More)
In order to evaluate the vocal quality of tracheo-oesophageal and oesophageal speech, several objective acoustic parameters were measured in the acoustic waveform (fundamental frequency, waveform perturbation) and in the frequency spectrum (harmonic prominence, spectral slope). Twelve patients using tracheo-oesophageal speech (with the Provox valve) and 12(More)
BACKGROUND Pigmented villonodular synovitis (PVNS) is considered to be a neoplastic-like disorder of the synovium histologically characterised by villonodular hyperplasia, resulting in dense fibrosis and haemosiderin deposition. The pathogenesis of the disease is still unknown. CASE REPORT A patient presented with severe treatment resistant PVNS of the(More)
BACKGROUND Various cytokines and inflammatory mediators are known to be involved in the pathogenesis of rheumatoid arthritis (RA). We hypothesized that polymorphisms in selected inflammatory response and tissue repair genes contribute to the susceptibility to and severity of RA. METHODS Polymorphisms in TNFA, IL1B, IL4, IL6, IL8, IL10, PAI1, NOS2a, C1INH,(More)
