Two-dimensional direct numerical simulation (2-D DNS) is used to investigate the effect of turbulence intensity and composition stratification on H2/air mixture auto-ignition in a constant volume enclosure relevant to homogeneous charge compression ignition (HCCI) engines. Different turbulence levels, composition fluctuations, EGR (Exhaust Gas Recirculation) ratios, initial pressure, domain length

A life-view can be described an an overall view of man and the world. An individual's life-view can change as a result of attending university. The life-view determines the response to reality and influences decision making and the treatment of other people. The aim of this study is to compare life-views and ethical viewpoints in the same group of physiotherapy students in their first and last sem

The interest for effective preventive strategies for slips and falls is growing. Much remains to be done, however, to prevent slips and falls in the traffic environment. Some pedestrians are injured because of slippery pavements and roadways. Using an appropriate anti-skid device may reduce the risk of slips and falls on different surfaces outdoors during winter. The aim of this study was to evalu

Background: Domestic violence during pregnancy is not only a severe public health issue that jeopardizes maternal and foetal health but also violates human rights. The aim was to explore the prevalence and incidence of domestic violence among pregnant women, in the southwestern region of Scania in Sweden, and their experience of a history of violence. In addition, to explore the association betwee

Computers are used in the outdoors and in connection with cold store work. Cold hand and fingers limit data input, as studied here. Six input devices; trackballs, pens, and a mouse were tested by 19 participants in a Fitts' target acquisition task with 2 target sizes under 2 experimental conditions; warm and cold right hand. Measures were acquisition times, number of errors, participant's preferen

This study addresses computer work in cold environments with the two-fold aim to explore conditions for such work, and to add knowledge about the use of fingers at data entry in the cold. Five workplaces were visited and work contents and use of computers are briefly described. Effects of work in the cold were in line with those mentioned in the literature, and manual lifting of heavy goods the mo

A four-week rehabilitation programme for back patients, focusing on functional activities and psychosocial factors in the demands of work and daily living, was evaluated. The programme is a combination of training of functional activities and increased psychological knowledge, body awareness and coping. A total of 40 patients with lumbago or lumbago ischias participated in the program and were com

Every year there are thousands of pedestrians in Sweden who are injured because of slippery pavements and roadways. Using an appropriate anti-skid device may reduce the risk of slips and falls on ice and snow. Methods to describe functional problems in walking on different slippery surfaces during winter have been developed as rating scales for evaluating walking safety and walking balance and an

High-precision analyses of the isotopic composition of methane in ambient air can potentially be used to discriminate between different source categories. Due to the complexity of isotope ratio measurements, such analyses have generally been performed in the laboratory on air samples collected in the field. This poses a limitation on the temporal resolution at which the isotopic composition can be

The aim of this article is to elaborate the concept of the physiotherapist - patient relationship, taking counselling and psychotherapeutic encounters as the model. The relationship is described as consisting of three components: the working alliance, the transference configuration, and the real relationship. The model of interactions between the therapist and the patient during physiotherapeutic

A life-view is an overall view of man and the world, forming a central value system and giving expression to a fundamental attitude. Research has shown that life-views are established early in childhood, are influenced by social environment and are relatively constant over time. An individual's view of life determines the response to reality and influences decision-making and treatment of other pe

Buildings are getting taller due to increased urbanisation and densification of cities. More advanced construction methods and the desire to construct impressive buildings is also supporting the trend. Due to their inherent slenderness resulting in low eigenfrequencies, these buildings are susceptible to wind-induced vibrations which can be highly disturbing for occupants. Already barely perceivab

The study of atomic nuclei far from the line of β-stability by means of radioactive ion beams is undertaken at several large-scale facilities throughout the world. These proceedings summarize high-resolution γ-ray spectroscopy investigations based on relativistic radioactive ion beams produced and prepared by the SIS/FRS facility of the GSI Helmholtz-Centre for Heavy-Ion Research and a brief outlo

Ground vibration from traffic is a source of nuisance in urbanized areas. Trenches and wave barriers can provide mitigation of vibrations, but single barriers need to have a large depth to be effective - especially in the low-frequency range relevant to traffic-induced vibration. Alternatively, periodic repetitions of mass, stiffness or both in an infinite structure lead to so-called stop bands in

In the atmosphere nighttime removal of volatile organic compounds is initiated to a large extent by reaction with the nitrate radical (NO3) forming organic nitrates which partition between gas and particulate phase. Here we show based on particle phase measurements performed at a suburban site in the Netherlands that organic nitrates contribute substantially to particulate nitrate and organic mass

Vibration of machinery and construction work are major sources of noise and vibration pollution in the urban environment. The frequencies dominating the vibration, and the distances over which it spreads via the ground, depend on the source. However, soil stratification and foundation type have a significant influence. Thus, in order to achieve fair accuracy in the prediction of ground vibration c
