The processes that led to the formation of the planetary bodies in the Solar system are still not fully understood. Using the results obtained with the comprehensive suite of instruments onboard the European Space Agency's Rosetta mission, we present evidence that comet 67P/Churyumov-Gerasimenko likely formed through the gentle gravitational collapse of a bound clump of mm-sized dust aggregates ('
An generalised engineering approach based on the analogy between mass and heat transfer is proposed to benchmark the shell-side mass transfer coefficient for axial flow in hollow fibre modules from low to moderate packing densities. The trends obtained by this approach are similar to those of correlations found in the literature and differences between the approaches are discussed. Furthermore,
Blood flow measurements in the ascending aorta and pulmonary artery from phase-contrast magnetic resonance images require accurate time-resolved vessel segmentation over the cardiac cycle. Current semi-automatic segmentation methods often involve time consuming manual correction, relying on user experience for accurate results. The purpose of this study was to develop a semi-automatic vessel segme
Measures for the reduction of electric energy loads for lighting have predominantly focussed on increasing the efficiency of lighting systems. This efficiency has now reached levels unthinkable a few decades ago. However, a focus on mere efficiency is physically limiting, and does not necessarily ensure that the anticipated energy savings actually materialise. This paper presents a literature surv
The age relationship between sunburns and malignant melanoma was investigated in a population-based, matched, case-control study from the South Swedish Health Care Region (the highest risk area for melanoma in Sweden). Between 1988 and 1990, a total of 400 patients with a first diagnosis of malignant melanoma and 640 healthy controls aged 15-75 years answered a comprehensive questionnaire includin
Denna rapport är resultatet av ett projekt vars syfte har varit att bygga upp en forskningsdatabas över och kartera svenska mikro-/hantverksbryggerier verksamma under främst 2000-talet. Sammanställningen har skett genom insamling, systematisering, lagring, analys och visualisering av bryggeridata utifrån geografiska platser. Forskningsdatabasens användbarhet exemplifieras genom analyser med stöd a
The radiometric distortion of reflected radiation received by the NOAA AVHRR sensor is brought on by the effects of viewing and solar illumination geometry, as well as atmospheric effects. This may lead to a gross underestimation of bioproductivity or crop yield from models which use high temporal resolution NOAA AVHRR data as an input. Accordingly, a simple angular correction method is presented
We critically assess mainstream accounting and finance research applying methods from computational linguistics (CL) to study financial discourse. We also review common themes and innovations in the literature and assess the incremental contributions of work applying CL methods over manual content analysis. Key conclusions emerging from our analysis are:(a) accounting and finance research is behin
This paper provides an overview of Subtask B: Tools and methods for solar design, of IEA SHC Task 41: Solar energy and architecture, 2009-2012. The focus of this Subtask was on identifying obstacles that architects are facing when implementing passive and active solar strategies in their design, especially during the early design phase (EDP) of building projects. The results of this Subtask also a
Background - Intravascular thrombosis occurs in disorders of diverse pathogeneses, including allograft and xenograft rejection. In this in vitro study, we describe an approach for tethering the specific thrombin inhibitor hirudin to plasma membranes as part of a genetic strategy for regulating intravascular coagulation. Methods and Results - An HLA class I leader sequence was fused with hirudin li
Background: We set out to estimate net survival trends for 10 common cancers in 279 cancer registry populations in 67 countries around the world, as part of the CONCORD-2 study. Net survival can be interpreted as the proportion of cancer patients who survive up to a given time, after eliminating the impact of mortality from other causes (background mortality). Background mortality varies widely be
In this study we examined the involvement of the focal adhesion-associated proteins p125FAK and paxillin as substrates for bradykinin (BK)-stimulated tyrosine phosphorylation in Swiss 3T3 cells and the potential role of protein kinase C and Ca2+ in these events. BK (1 UM) stimulated tyrosine phosphorylation of p125FAK and paxillin. In addition, BK also increased the phosphotyrosine content of the
In the recovery phase after a radioactive release incident, it is important to be able to focus decontamination operations on the areas that contribute most to the radiation dose. Monte Carlo simulations were applied to determine the shielding effect of a building against radiation from various directions, also giving information on the dose contributions at various locations inside the building f
The need for frequent retreatment is a disadvantage of using endoscopic laser therapy (ELT) alone for palliative treatment of esophageal carcinoma. In this prospective study, therefore, we investigated the potential and feasibility of combining ELT with a self-expanding metallic stent (Wallstent). Twelve patients received ELT followed by stent placement (stent group) and were compared with 39 pati
Aims: The aim of this study was to test a Child-Centred Health Dialogue model for primary prevention of obesity for 4-year-old children in Child Health Services, for its feasibility and the responsiveness of its outcomes.Methods: A feasibility study was set up with a non-randomised quasi-experimental cluster design comparing usual care with a structured multicomponent child-centred health dialogue
The reduction of public expenditure and investments in health care provisioning calls for new, sustainable models to transform the increasing aging population and dementia-related diseases incidence from global challenges into new opportunities. In this context, Information and Communication Technologies play a vital role, to both promote aging in place and home management of Patients with Dementi
