Successful implementation of plasma-assisted combustion in applied thermal processes heavily relies on how the plasma can be formed as it interacts with the reactive flow and what the effects are of such a plasma on the combustion process. The current study is an experimental investigation of a plasma-assisted lifted flat methane–air flame by a nanosecond pulsed discharge at atmospheric pressure.
Background Orthognathic surgery addresses facial aesthetics and function in patients with dentofacial deformities. It is associated with changes in upper airway volume (UAV). If changes in UAV is perceived by asymptomatic patients is unclear. Purpose The purpose was to measure associations between changes in UAV and patient-reported benefits using patient-reported outcome measures (PROM). Study de
We report on a quantum dots-in-a-well infrared photodetector (DWELL QDIP) grown by metal organic vapor phase epitaxy. The DWELL QDIP consisted of ten stacked InAs/In0.15Ga0.85As/GaAs QD layers embedded between n-doped contact layers. The density of the QDs was about 9 x 1010 cm-2 per QD layer. The energy level structure of the DWELL was revealed by optical measurements of interband transitions, an
From a control design point of view, modern diesel engines are dynamic, nonlinear, MIMO systems. This paper presents a method to find low-complexity black-box dynamic models suitable for model predictive control (MPC) of NOx and soot emissions based on on-line emissions measurements. A four-input-five-output representation of the engine is considered, with fuel injection timing, fuel injection dur
Objective. To assess the clinical utility of repeat sacroiliac joint computed tomography (CT) in sacroiliitis by assessing the proportion of patients changing from normal to pathologic at CT and to which degree there is progression of established sacroiliitis at repeat CT. Methods. In a retrospective analysis of 334 patients (median age 34 years) with symptoms suggestive of inflammatory back pain,
The macrocyclic ketone (MK) group of fragrance ingredients was evaluated for safety following a complete literature search. For high end users, calculated maximum dermal exposures vary from 0.13% to 1.10%; systemic exposures vary from 0.0005 to 0.0441 mg/kg/day. The MKs had low acute toxicity and no significant repeat dose toxicity. Liver weight and blood biochemistry effects were reversible after
The natural history of oncogenic human papillomavirus (HPV) infections results from interactions of the virus, the host, and multiple cofactors. We studied the association between humoral immune response to HPV and smoking in 191 HPV infected women prospectively. Two follow-up samples (first and last) were analysed for serum cotinine levels, IgA and IgG antibodies to HPV16 and 18, and Chlamydia tr
In photonuclear experiments precise location of the photon beam relative to the experimental sample is critical. Previously used techniques such as using photographic film to identify the position, intensity and centroid of the beam is time-consuming and a faster method is required. PILATUS is a single-photon-counting pixel detector developed at the Paul Scherrer Institute (PSI), Switzerland. It i
Trapping and ringing near ecological barriers can provide useful information about the migration strategies of bird species. In this paper we analyzed ringing data of the Garden Warbler, collected within the period of 1950-2008 at the Ottenby Bird Observatory, south-eastern Sweden, and describe patterns in migration phenology, morphometrics and fuel load. A total of 4,351 individuals aged as eithe
The surface emissions trap, an adsorption cloth developed for reducing emissions of volatile organic compounds and particulate matter from surfaces while allowing evaporation of moisture, was used to improve the indoor air quality of a school building with elevated air concentrations of 2-ethyl-1-hexanol. An improvement of the perceived air quality was noticed a few days after the device had been
Injury to the brain (e.g., stroke) results in a disruption of neuronal connectivity and loss of fundamental sensori-motor functions. The subsequent recovery of certain functions involves structural rearrangements in areas adjacent to the infarct. This remodeling of the injured brain requires trafficking of macromolecular components including cholesterol and phospholipids, a transport carried out b
The inclusive transverse momentum (p(T)) distributions of primary charged particles are measured in the pseudo-rapidity range vertical bar eta vertical bar <0.8 as a function of event centrality in Pb-Pb collisions at root S-NN = 2.76 TeV with ALICE at the LHC. The data are presented in the p(T) range 0.15 < p(T) <50 GeV/c for nine centrality intervals from 70-80% to 0-5%. The results in Pb-Pb are
Phytase is used as a feed additive for degradation of antinutritional phytate, and the enzyme is desired to be highly thermostable for it to withstand feed formulation conditions. A Bacillus sp. MD2 showing phytase activity was isolated, and the phytase encoding gene was cloned and expressed in Escherichia coli. The recombinant phytase exhibited high stability at temperatures up to 100 degrees C.
In recent years a lot of criticism against the main assumptions of economic modeling has come to up, this has led to physicists entering the field of economics. By applying models originally developed for physics to economics, especially finance, analyzing methods with a different approach can be used. Inspired by earthquakes Didier Sornette created a model that analyze financial market crashes. W
The thesis aims at supplementing a critique of the existing international instruments, regional responses and national legislation of the Arctic related to marine environmental protection. With this aim in view, the thesis satisfies its objective by proposing a Bipartite “Arctic Council” acting as a conglomeration of the Arctic States and the Flag States with a hybrid “Arctic treaty”, which is an
Syftet med denna tvärsnittsstudie var att undersöka barns förståelse för empatiska reaktioners relationella innebörd och om denna skiljer sig beroende på ålder, samt undersöka om samband fanns mellan denna förmåga och förmåga till socialt perspektivtagande. Undersökningen jämförde barn i grundskolans årskurs 2 (n = 15, M = 8:7 år), årskurs 5 (n = 17, M = 11:8 år) och årskurs 8 (n = 13, M = 14:10 åThis cross-sectional study explored children’s understanding of empathic reactions relational meaning and if this understanding increases with age. It also explored an association between this ability and ability for social perspective taking. Comparisons were made between second graders (n = 15, M = 8:7 years), fifth graders (n = 17, M = 11:8 years) and eighth graders (n = 13, M = 14:10 years). T
