This paper report on experiments performed using a dielectric barrier surface discharge to increase the combustion rate in a Bunsen-type burner. The burner has a coaxial geometry where premixed fuel-air flows in the outer annular tube while a jet of air can be injected through the central tube, thus increasing turbulent mixing and flame speed. When the central jet is used the power density but not
It is well known that planar self-complementary structures have a constant input impedance and hence they are good candidates for ultra-wideband antennas. However, introduction of a ground plane breaks the symmetry and destroys the broadband property. In this paper, it is shown that stacking of dielectric slabs above the antenna elements can reduce the degrading eject of the ground plane. The diel
NOx pollution from Diesel engines causes over 10 000 premature deaths annually and the trend is increasing. In order to decrease this growing global problem, exhaust after-treatment systems for Diesel engines have to be improved. The most common SCR systems in the market place inject an aqueous Urea solution, DEF that evaporates prior the catalytic surface of the SCR-catalyst. Due to a catalytic r
Protein G is a streptococcal cell wall protein with separate and repetitively arranged binding domains for immunoglobulin G (IgG) and human serum albumin (HSA). In this work, the binding of protein G to HSA was studied. The results suggest that a single binding site is present on HSA: the apparent size of the HSA-protein G complex (230 kDa) corresponded to two or three HSA molecules bound to one p

To prospectively study the prevalence of Lyme arthritis, 100 consecutive patients referred to a rheumatology out-patient clinic and 115 patients with a classified rheumatological disease were included. Individuals seropositive for antibody against the Borrelia burgdorferi sensu lato complex were examined for clinical signs or a history of Lyme borreliosis. Positive titres against B. burgdorferi s.
The treatment of rheumatoid arthritis is currently based on pathogenesis and pathophysiology, being the etiology still unknown. At cognition and activation phase of rheumatoid arthritis, there is a number of potential therapeutic approaches, still in development and in early trials. At inflammation and even more at invasive phase of rheumatoid arthritis, the treatment should take into consideratio

Objective and methods: Time-use methodologies have been proposed to be established research techniques when exploring aspects of daily occupations. In this study, two graphs illustrating the time arrangement of occupations as they appear in a continuous sequence were used in order to encourage individuals to reflect on their everyday life. The aim was to investigate the usefulness of a time-geogra
Background: Internet-delivered cognitive behavioural therapy (ICBT) is an effective and accessible treatment for mild to moderate depression and anxiety disorders. However, up to 50% of patients do not achieve sufficient symptom relief. Identifying patient characteristics predictive of higher post-treatment symptom severity is crucial for devising personalized interventions to avoid treatment fail
OBJECTIVE: To investigate the possible association between severity of intellectual disability (ID) and presence of challenging behavior, respectively, on diagnoses of psychiatric disorders among older people with ID.METHODS: People with a diagnosis of ID in inpatient or specialist outpatient care in 2002-2012 were identified (n = 2147; 611 with mild ID, 285 with moderate ID, 255 with severe or pr
