A directly enhanced cooled winding in an electrical traction machine has the potential to extend the operation range, which is in particular attractive for a traction application when operating near peak power for extended periods of time. This paper presents the heat transfer analysis of a modular machine segment with a laminated winding. The laminated winding has a great potential when it comes
Objective: To examine reliability and validity of the Swedish version of the Self-Efficacy for Rehabilitation (SER) outcome scale. Methods: One-hundred and ninety-eight inpatients (mean age 69 years) who underwent a primary total knee arthroplasty (TKA) due to knee osteoarthritis participated. They responded pre- and postoperatively to the SER outcome scale, and preoperatively to the Hospital Anxi
PM in diesel exhaust has been given much attention due to its adverse effect on both climate and health. As the PM emission levels are tightened, the portion of particles originating from the lubrication oil is likely to increase. In this study, exhausts from a biodiesel-fueled Euro 5 engine were examined to determine how much of the carbonaceous particles that originated from the fuel and the lub
Background: Radiography as a concept has mainly been associated with the functional role of the radiographer. The concept has been studied from a theoretical point of view. However, there is a lack of a theoretical foundation and research on the actual substance of the term radiography used in education. It is therefore important to undertake an investigation in order to determine how students aft
The paper presents a large eddy simulation investigation on the effect of fuel injection pressure on mixing, in an optical heavy-duty diesel engine. Recent investigation on impinging wall jets at constant-volume and quiescent conditions exhibited augmented air entrainment in wall jets with increasing injection pressure, when compared with a free jet. The increased mixing rates were explained as ow
Deep tissue excitation of upconverting nanoparticles is limited for biomedical applications by water absorption. By modifying the nanoparticles to shift the excitation wavelength, we demonstrate better depth sensitivity.
Andersson M., Klaesson J. and Larsson J. P. How local are spatial density externalities? Neighbourhood effects in agglomeration economies, Regional Studies. The geographic scale at which density externalities operate is analysed in this paper. Using geocoded high-resolution data, the analysis is focused on exogenously determined within-city squares (‘neighbourhoods’) of 1 km2. The analysis confirm
The effects of extract of apple peel, 'Aroma', organically cultivated or cultivated according to integrated production, on cell proliferation in vitro of colon cancer HT29 cells and breast cancer MCF-7 cells, were investigated. Different sequences of solvents were used, and the inhibiting effect on cancer cell proliferation of the different extracts was investigated. The solvents used were ethanol
A polyethylene plant at Borealis AB is modelled in the Modelica language and considered for parameter estimations at grade transitions. Parameters have been estimated for both the steady-state and the dynamic case using the JModelica.org platform, which offers tools for steady-state parameter estimation and supports simulation with parameter sensitivies. The model contains 31 candidate parameters,
Med anledning av den nära förestående helgonförklaringen av Elisabeth Hesselblad skriver nu Yvonne Maria Werner, professor på Historiska institutionen vid Lunds universitet, om moder Hesselblads syn på kristen enhet. Hur såg egentligen Elisabeth Hesselblad på ekumeniken? Vad är sant – och vad är myt? Yvonne Maria Werner reder ut begreppen.
A personal computer program, FiFi, that makes a real-time two-dimensional simulation of the dynamic deposition process of particles on one or two fibres, has been developed. The code has been used to numerically calculate the collection efficiencies of spherical particles on a clean single fibre. The calculations are based on a 10 term expansion of a solution of Oseen's approximation of Navier-Sto
In many application domains, critical systems must comply with safety standards. This involves gathering safety evidence in the form of artefacts such as safety analyses, system specifications, and testing results. These artefacts can evolve during a system's lifecycle, creating a need for impact analysis to guarantee that system safety and compliance are not jeopardised. Although extensive resear
Diffusion tensor imaging (DTI) is the method of choice for non-invasive investigations of the structure of human brain white matter (WM). The results are conventionally reported as maps of the fractional anisotropy (FA), which is a parameter related to microstructural features such as axon density, diameter, and myelination. The interpretation of FA in terms of microstructure becomes ambiguous whe
The win-win opportunities connected to green growth are appealing to academics and policy makers alike, but empirical evaluations about the effectiveness of green growth policies are still scattered. Taking South Korea as case study, which set up a highly ambitious green growth program in 2009, our research casts light on the extent to which the Korean Green Growth Strategy has been effective in d
Risk and vulnerability analyses are a required decision support tool in processes to improve societal safety and crisis preparedness at national, regional and local levels in several European states. Analyses result in risk images, which are the stakeholders’ views of events that must be addressed in planning processes related to topics such as land use and crisis management. Hence, risk and vulne
Today risk analyses are commonly used by authorities at national, regional and municipal levels in their work to prevent and prepare for crises. The analyses provide information about types of incidents that can occur and the potential consequences of these events. In Sweden and Norway it is mandatory for local authorities to conduct risk and vulnerability analyses and use them as an input in thei
