Irradiating a flame by microwave radiation is one of several plasma-assisted combustion (PAC) technologies that can be used to modify the combustion chemical kinetics in order to improve flame-stability and to delay lean blow-out. One practical implication is that engines may be able to operate with leaner fuel mixtures and have an improved fuel flexibility capability including biofuels. In additi
Abstract in UndeterminedTemperature and relative O-2-concentrations have been measured using pure rotational coherent anti-Stokes Raman spectroscopy (RCARS) in a low swirl turbulent premixed flame. This lean flame burning methane has previously been investigated using laser diagnostic techniques and numerical modeling of flame characteristics. In the present work, single-shot RCARS measurements we
Large eddy simulation of diesel spray in a constant volume vessel as well as in an internal combustion engine has been performed. Spray is modeled using Eulerian-Lagrangian approach. The modeling involves primary and secondary break-up, the spray-induced turbulence (SIT) and the stochastic turbulence dispersion (STD) of parcels. Including SIT, based on Baharawaj et al. (2009), in coarse grids, e.g
Combining historical climatology and environmental history, this article examines the diverse range of strategies deployed by the city government of Barcelona (Catalonia, NE Spain) to confront the recurrent drought episodes experienced between 1626 and 1650. Our reconstruction of drought in Barcelona for the period 1525-1821, based on pro pluvia rogations as documentary proxy data, identifies the
The aim of this study was to examine the effects of risedronate (5 mg/daily) in patients identified solely on the basis of a prior fragility fracture, without BMD as an inclusion criterion. A total of 1,802 patients were examined from the VERT-NA and VERT-MN clinical trials. Lateral radiographs (T4 to L4) were obtained at baseline and annually; incident fractures were evaluated using quantitative
BACKGROUND: National quality registries (NQRs) provide open data for user-directed acquisition. National Quality Registry (NQR) data are often used to analyze the rates of treatment success and adverse events for studies that aim to improve treatment quality and patient satisfaction. Thus, NQRs promote the goal of achieving evidence-based therapies. However, the scientific literature seldom focuse
I Sverige försvinner varje år ett stort antal skogslevande arter, vilket är ett allvarligt hot mot vår biologiska mångfald. Trots att skogen ofta uppfattas som en artfylld och hållbar miljö, är verkligheten en annan. Det intensiva skogsbruket har lett till en dramatisk minskning av många arters livsmiljöer. Så vad gör skogsindustrin åt saken? Denna studie lägger fokuset på skogsin- dustrins egna oThe Swedish forest is subject to significant pressure from the forestry industry. As a consequence, biodiversity is negatively affected. Sustainability reporting serves as a means for consumers and stakeholders to gain insight into companies' sustainability ef- forts. Reporting on biodiversity is relatively new compared to climate reporting and poses greater challenges in terms of quantificati
Ammonia combustion in gas turbines is emerging as a carbon-free solution for the power-generation sector. The challenges associated with using ammonia as a fuel include its combustion characteristics, which can lead to instability, and the emission of NOx due to the presence of nitrogen atoms. This study examines the diffusion flames of partially cracked ammonia at low cracking degrees and the air
Gängkriminaliteten och dödsskjutningar har blivit ett allvarligt problem i Sverige, vilket väcker frågor om hur problemet ska hanteras. Införandet av säkerhetszoner har föreslagits som ett verktyg för att bekämpa kriminaliteten och öka tryggheten för medborgarna. Säkerhetszonen ger polisen utökade be- fogenheter att utan konkret brottsmisstanke genomföra kroppsvisitationer och genomsöka fordon i sGang-related crime and fatal shootings have become a serious issue in Swe- den, raising the questions about how the problem should be handled. The in- troduction of security zones has been proposed as a tool to combat crime and enhance public safety. Security zones grant police extended authority to con- duct body searches and search vehicles without concrete suspicion of crime, in order to find w
Objective: In lymphedema management, lower limb volume is commonly assessed by circumference measurementevery 4th cm which is however time-consuming. The aim of this study is to evaluate the agreement between volumemeasurements derived from circumference measurements every 4th cm (V4) with every 8th cm (V8) and every 12th cm(V12) in patients with lower limb lymphedema (LLL) and to determine the te
In partially premixed combustion engines high octane number fuels are injected into the cylinder during the late part of the compression cycle, giving the fuel and oxidizer enough time to mix into a desirable stratified mixture. If ignited by auto-ignition such a gas composition can react in a combustion mode dominated by ignition wave propagation. 3D-CFD modeling of such a combustion mode is chal
Experimental and numerical studies were performed to understand the stabilization of lean premixed natural gas/air flames in a gas turbine model combustor which was equipped with a swirl burner, known as the CECOST burner, designed to replicate the flow and flame structures in an industrial gas turbine engine. The operability range, flame stabilization, and flashback were investigated employing si
Abstract in Italian Arthur Prior (1914-1969) si è occupato di temi che spaziano dalla logica formale all'etica, ed ha fornito contributi di grandissima importanza soprattutto nell'ambito della logica modale, della metafisica, e della filosofia del tempo. E' considerato il padre della logica temporale e il precursore della contemporanea logica ibrida, è stato un precursore della semantica a mondi p
