Differential migration has been extensively reported in spring, but less so in autumn, particularly in relation to sex in monomorphic bird species. Here, we analysed the autumn passage of a monomorphic, globally threatened passerine, the Aquatic Warbler Acrocephalus paludicola throughout Western Europe, with regard to age and sex. We showed that, overall, adults migrated earlier than first-year bi

Photoinduced electronic and structural changes of a hydrogen-generating supramolecular RuPt photocatalyst are studied by a combination of time-resolved photoluminescence, optical transient absorption, and X-ray absorption spectroscopy. This work uses the element specificity of X-ray techniques to focus on the interplay between the photophysical and -chemical processes and the associated time scale

Activation of the complement system and resulting opsonisation with C3b are key events of the innate immune defense against infections. However, a wide variety of bacterial pathogens subvert complement attack by binding host complement inhibitors such as C4b-binding protein, factor H and vitronectin, which results in diminished opsonophagocytosis and killing of bacteria by lysis. Another widely us

Canon and oblivion. The memorials of archaeology The Sun-Chariot from Trundholm is world famous, and the finding place is marked with a monument. In the same way the finding places for The golden horns from Gallehus, the Egtved girl, the Dejbjerg chariots, the Gundestrup cauldron, the Nydam boat and many other finds have been remembered during the 20th Century with memorials, often a stone monum

n the past two decades, medical anthropology has increasingly turned its attention to the global, including ethnographic fieldwork at global health mega-events and the processes behind global health initiatives. Similar developments have taken place in political and legal anthropology, with researchers looking at United Nations organizations, transnational epistemic communities, and other global s

The meninges are important for brain development and pathology. Using single-cell RNA sequencing, we have generated the first comprehensive transcriptional atlas of neonatal mouse meningeal leukocytes under normal conditions and after perinatal brain injury. Weidentified almost all known leukocyte subtypes and found differences between neonatal and adult border-associated macrophages, thus highlig

This is an interview-based study that aims to test the validity of the Agenda Setting Theory. As it was written before the Information Age, it claims that the public agenda (readers) have no real influence over the media agenda (newspapers). As the digitalization of journalism made analytical tools widely available to web editors, it may be possible that the media agenda today is much more depende

The main goal for year 2050 is to reduce energy usage by 50 %. This is meant to be achieved through the use of energy efficient solutions. Operation and maintenance of installations and buildings are main factors in achieving this goal. The building must be viewed from a holistic perspective throughout the process. With regards of both optimization of installations and improvements of the construc

RNA interference (RNAi) has recently been discovered in the budding yeast Saccharomyces castellii. As in other organisms, artificial RNAi could be a useful genetic tool in budding yeast, but the method needs first to be established. S. castellii is also a useful model for telomerase studies, and a knockdown of the telomerase catalytic subunit Est2p could be a new way of unrevealing its functions a

Populärvetenskaplig sammanfattning: Klimatväxlingarna under sista istiden har alltid varit en debattfråga. Denna istids kallaste period inträffade för cirka 20.000 år sedan och benämns "istidsmaximum". Då var havsytan hundratjugo meter lägre än idag och det mesta vattnet var bundet i inlandsisarna. Klimatväxlingar försöker dagens kvartärgeologer att fastställa med en så bra tidsutlösning

This report is an evaluation of the fire safety at Jakobsberg's hospital outside Stockholm. The report is a part of the course in Fire Safety Evaluation that is given at the Faculty of Engineering at Lund University. The evaluation follows a scheme that was developed on a basis of prior learning at the Fire Protection Engineering Program and focuses on risks concerning life and health. The wor

The ongoing surge in internet users worldwide and its complexity causes organisations to digitally transform to stay competitive. Previous research repeatedly emphasised the importance of digital transformation, but the authors see a gap in the literature regarding digital transformation. General change management models have been around, but a more focused framework for digital transformation is
