In this study, the effects of fin configurations and layouts on thermal and hydraulic performances of printed circuit heat exchangers (PCHEs) with supercritical liquefied natural gas as the working fluid are studied by a numerical method, and the overall heat transfer performance of various parameters is evaluated by the JF factor. Firstly, the effect of four different airfoil configurations, i.e.

Aims The aims were to investigate the association between maternal serum levels of perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA), perfluorohexane sulfonate (PFHxS) and perfluorononanoic acid (PFNA) in early pregnancy and overweight in the child at 4 years and to assess potential heterogeneity in exposure effect between strata with different levels of other risk factors for overwe

The overall aims of this thesis were to improve prediction, diagnostics and knowledge on epidemiology of sepsis. In paper I, we developed and evaluated an integrated platform for rapid analysis of sepsis-causing organisms directly from blood samples. Testing with blood samples spiked with bacteria and samples from septic patients indicate that the detection limit of the system is in the upper partThe overall aims of this thesis were to improve prediction, diagnostics and knowledge on epidemiology of sepsis.

Efficient protection of huge amount of IoT produced data is key for wide scale data analytic services. The most efficient way is to use pure symmetric encryption as that allows both fast decryption at the analytic engine side as well as energy efficient encryption at the IoT side. However, symmetric encryption can only be performed if there is a way to directly map an encrypted object to the corre

Energy flow is a central characteristic in all ecosystems, and it has attracted considerable scientific attention due to its significant effects on the stability of food webs. Lake ecosystems that undergo regime shifts (clear water phase, phytoplankton dominated changed into turbid water, macrophytes dominated or vice versa) are characterized by a series of transformation in trophic structure. Alt

In this climate change and biodiversity loss focus, Harriet Bulkeley, Professor at Durham University in the UK and Kes McCormick, Associate Professor at Lund University in Sweden, argue that nature-based solutions in the city are not just for the birds.

The Governance of Urban Sustainability Transitions project was established to examine, inform and advance the governance of sustainability transitions through urban living labs. The findings could help address many of the economic, social and environmental concerns of the 21st century.

Sharing Cities Sweden aims to put Sweden on the map as a country that actively and critically works with the sharing economy in cities. We are developing world-leading test-beds for the sharing economy in Stockholm, Gothenburg, Malmö and Umeå. We are developing a national node to significantly improve national and international cooperation and promote an exchange of experience on sharing cities.

BACKGROUND: Continuity models of midwifery care are rare in Sweden, despite its well-known positive effects. The aim was to describe pregnancy and birth outcome in women participating in a continuity of care project in a rural area of Sweden.METHOD: A register-based study of 266 women recruited to the project and a control group of 125 women from the same catchment area. Midwives provided antenata

OBJECTIVE: Although fear of birth is common during pregnancy and childbirth, the best treatment for fear of birth in clinical care remain unclear. Strong evidence suggests that continuity models of midwifery care can benefit women and birth outcomes, though such models are rare in Sweden. Because women with fear of birth could benefit from such models, the aim of this qualitative study was to exam

Wildfire occurrence is influenced by climate, vegetation and human activities. A key challenge for understanding the risk of fires is quantifying the mediating effect of vegetation on fire regimes. Here, we explore the relative importance of Holocene land cover, land use, dominant functional forest type, and climate dynamics on biomass burning in temperate and boreo-nemoral regions of central and

Wind energy is an important source of bat mortality worldwide. Extensive mortality data were gathered by a provincial surveillance program carried out at wind farms in lowland Mediterranean areas of the province of Cadiz, Andalusia (South Spain) between 2005 and 2016. As many as 2,371 bat fatalities were found. We determined the patterns of fatality in this sample and tested the quality of the sur

Objective: The aim of this study was to explore the "Birth Attitude Profile Scale (BAPS)" in a selected sample of women with fear of birth. Another aim was to develop profiles of women according to their birth attitudes and levels of childbirth fear in relation to background characteristics.Methods: A secondary analysis of data collected in two different samples of women with fear of birth. Data w

The acceleration of developing magnesium alloys for biomedicine requires the advancement of experimental methods evaluating their performance. We have been developing an advanced immersion testing method for the assessment of biomedical Mg alloy degradation in aqueous environments. It is based on the combination of isothermal calorimetry with pressure measurement in the reaction cell. Such a combi

Developments in medical technology and treatment have increased the survival rates of children with serious illnesses or injuries, including those receiving home mechanical ventilation, which is a small but growing group. The aim of this study was to explore everyday life experiences of children and young people living with home mechanical ventilation (HMV). Data were obtained through interviews w

Background: Currently, it is well known that the sound environment in intensive care units (ICU) is substandard. Therefore, there is a need of interventions investigating possible improvements. Unfortunately, there are many challenges to consider in the design and performance of clinical intervention studies including sound measurements and clinical outcomes. Objectives: (1) explore whether it is

Introduction It has been known for centuries that environment in healthcare has an impact, but despite this, environment has been overshadowed by technological and medical progress, especially in intensive care. Evidence-based design is a concept concerning integrating knowledge from various research disciplines and its application to healing environments. Objective The aim was to explore the expe
