Microsoft Word - Jiffy_press_eng.docx JULIA SJÖLIN JIFFY 3 APRIL–18 APRIL 2020 Julia once told me about a project which point of departure was to collect glass that had been formed by lightning striking sand. The project never happened but the glass and the discharge of energy from which the lightning emerge, still plays a central role in Julia Sjölin's practice and consequently in this exhibition

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

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

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

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

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

Purpose: To investigate the outcome following adjuvant doxorubicin and ifosfamide in a prospective non-randomised study based on a soft tissue sarcoma (STS) patient subgroup defined by specific morphological characteristics previously shown to be at a high-risk of metastatic relapse. The expected 5-year cumulative incidence of metastases in patients with this risk profile has previously been repor

The effects of the position of a bluff-body on diffusion flame structures and flame instability characteristics were investigated both experimentally and numerically. The flame pattern diagram and the stability limits of the methane-air diffusion flame were investigated to evaluate the effects caused by the alternation of the position of a bluff-body. A disk-shape bluff-body was mounted 10 mm abov

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

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

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

A series of experimental measurements on a prototype premixed swirl burner with complex geometry were carried out using CH2O/OH-PLIF. FGM method(SFGM)taking account of strain rate was developed to study two modes of premixed swirl flame, one stabilized and the other close to blown-off flame under the same Reynolds number(Re=10000). The SFGM model in this work is related to a reaction factor, which

In this paper, the flame-wall interaction of reacting diesel spray under engine like conditions is investigated using large eddy simulations. The aim of this study is to understand the influence of the distance between the wall and the spray nozzle on the air entrainment rate, which is a key variable in formation/oxidation process of soot. Three experimental cases are investigated, a free jet case

Protease inhibitors and protease (caseinolytic, elastinolytic and esterolytic) activity were analysed in 190 milk samples from 94 mothers from day 1 to day 160 after delivery The main protease inhibitors in human milk are α1-antichymotrypsin and α1-antitrypsin. As measured by electroimmunoassay, the level of α1-antichy-motrypsin in day 1 colostrum was higher than that in normal serum. Trace amount

Fundamental characteristics of the reaction-zone structure for CH4-CO2 jets, mimicking a fuel of high CO2 contents such as biogas, burning in a heated coflow on a piloted jet burner have been investigated. Jet flames under diffusion and MILD combustion conditions were studied using planar laser-induced fluorescence (PLIF) of O-atom radicals and CO for different CO2 contents of the fuel jet. Numeri
