Wind tunnels, in which birds fly against an artificially generated air flow, have since long been used to evaluate aerodynamic properties of steady bird flight. A new generation of wind tunnels has also allowed the many processes associated with migratory flights to be studied in captivity. We review how wind tunnel studies of aerodynamics and migratory performance together have helped advancing o
Haemophilia A is a congenital bleeding disorder characterised by recurrent haemorrhages into the major joints. Haemophilic arthropathy is a well-established outcome of recurrent joint bleeding; however, it is clear that multiple factors determine the extent and severity of its occurrence. We sought to identify genetic factors related to abnormalities in range of motion (ROM) in the knees, ankles a

Popular Abstract in Swedish Många människor tillbringar en stor del av dygnet på en arbetsplats, vilket innebär att det är en plats och en tid inte bara för arbete utan också för sociala relationer samt för mat och dryck. Maten, vare sig det handlar om lunchen klockan tolv, eftermiddagsfikan klockan tre eller chokladbiten under nattskiftet, bidrar till att skapa pauser i arbetet. Arbetsplatsen kanMany people spend hours in a workplace every week and food and drink play a central role in providing nutrition and energy and help to create breaks during the working day. However, meals are something more than the food consumed. This dissertation focuses on the meal at work, where the meal is surrounded by special circumstances when it comes to time, place and social relations, as well as the fo
We present a computational tool to develop an exhaust gas recirculation (EGR) - air-fuel ratio (AFR) operating range for homogeneous charge compression ignition (HCCI) engines. A single- cylinder Ricardo E-6 engine running in HCCI mode, with external EGR is simulated using an improved probability density function (PDF)-based engine cycle model. For a base case, the in-cylinder temperature and unbu
Abstract OBJECTIVES: To investigate the effects of antenatal betamethasone on fetal and uteroplacental hemodynamics. METHODS: The study comprised 33 women with singleton high-risk pregnancies (23-33 weeks; 27 pregnancies < 30 weeks) not in labor, but at risk for preterm delivery based on fetal or maternal indications. They were treated with two doses of 12 mg betamethasone intramuscularly 24 h ap
Cardiovascular risk increases with chronological as well as biological aging, and one marker of this might be telomere length. The telomere cap is located at the end of the DNA helix and serves to protect its end. This is an evolutionary adaptation which has resulted in stabilization of the DNA strand within the chromosome. During the life course, telomeres tend to shorten in most cells, with the
Evaluation, prioritization and selection of candidate requirements are of tremendous importance and impact for subsequent software development. Effort, time as well as quality constraints have to be taken into account. Typically, different stakeholders have conflicting priorities and the requirements of all these stakeholders have to be balanced in an appropriate way to ensure maximum value of the
What exactly are opinions? What does it mean to express an attitude? Given the ubiquitous use of surveys, polls and rating scales, it seems we ought to have firm answers to these fundamental questions, but we do not. Here we present a novel approach to investigate the nature of attitudes. We created a self-transforming paper survey of moral opinions, covering both foundational principles, and curr
