Most songbird migrants travel between their breeding areas and wintering grounds by a series of nocturnal flights. The exact nocturnal departure time for these flights varies considerably between individuals even of the same species. Although the basic circannual and circadian rhythms of songbirds, their adaptation to migration, and the factors influencing the birds' day-to-day departure decision

In this paper we have investigated the dynamics of photo-generated charge carriers in a series of aerotaxy-grown GaAs nanowires (NWs) with different levels of Zn doping. Time-resolved photo-induced luminescence and transient absorption have been employed to investigate radiative (band edge transition) and non-radiative charge recombination processes, respectively. We find that the photo-luminescen

Rent seeking is central to processes of financialisation and crisis formtation, not least in tourism economies. Rent seeking involves the making and taking of rent gaps geared to expand unearned incomes in the form of interest revenues from debt and rental revenues from property. Changes in built environments become increasingly determined by where rent gaps can be created and appropriated, rather

Sustainable agriculture requires nutrient management options that lead to a profitable crop yield with relatively low nitrogen (N) losses to the environment. We studied whether the addition of contrasting organic amendments together with inorganic fertilizer can promote both requirements simultaneously. In particular we studied how the chemical composition of organic amendments affects the biomass

The web of relationships between wellbeing and the environments in which people live has long been recognized. However, relatively little research has been conducted about end-of-life surroundings from the perspective of the dying person. In this study, we investigate which aspects of their surroundings are particularly meaningful for the people inhabiting them in the last phases of life, based on

CO2 fluxes and concentrations were simulated in the planetary boundary layer above subarctic hilly terrain using a three dimensional model. The model solves the transport equations in the local scale and includes a vegetation sub-model. A WMO/GAW background concentration measurement site and an ecosystem flux measurement site are located inside the modeled region at a hilltop and above a mixed bor

Cell-based therapies for Parkinson's and Huntington's disease have provided mixed clinical outcomes and one of the reasons underlying this is the use of primary fetal tissue as the source of grafted cells. An alternate source of cells, such as stem cells, could overcome many of the issues associated with primary fetal tissue and would help bring forward cell replacement therapy as a reliable and e

This article proposes a novel approach to blockmodeling of valued (one-mode) networks where the identification of (binary) block patterns in the valued relations differ from existing approaches. Rather than looking at the absolute values of relations, or examining valued ties on a per-actor basis (cf. Nordlund, 2007), the approach identifies prominent (binary) ties on the basis of deviations from

Suppression of nitrite oxidizing bacteria (NOB) is of vital importance to achieve successful, energy efficient, mainstream anammox processes for wastewater treatment. In this study, biofilm carriers from a fully nitrifying MBBR system, fed with mainstream wastewater, were temporarily exposed to reject water from sludge dewatering, to evaluate this as a possible strategy to inhibit NOB and achieve

The regional atmospheric model REMO is used to study the energy and water exchange between surface and atmosphere over the Baltic Sea and its catchment area. As a prerequisite for such studies, the model has to be validated. A major part of such a validation is the comparison of simulation results with observational data. In this study the DX product of the International Cloud Climatology Project

This article discusses the emergence of the episcopal see in Växjö. Contrary to previous research, which has been focused on written sources only, this article also discusses the archaeological record. The result implies that vivid connections between Scania, Denmark and southern Småland can be traced in the Late Iron Age and Early Middle Ages. This is shown by similarities in grave types, runic s

This study investigates older inhabitants’ appreciation of environmental measures taken in their residential area and the effect on perceived difficulty as pedestrians and in outdoor activity. The study is based on data collected with a mailed questionnaire at baseline and at a 5-year follow-up (after intervention) posted to 195 people aged 65+ in a residential area in a medium-sized Swedish town,

BACKGROUND: Accumulating evidence supports a role for the immune system in the pathogenesis of Parkinson's disease. Importantly, recent preclinical studies are now suggesting a specific contribution of inflammation to the α-synuclein-induced pathology seen in this condition.METHODS: We used flow cytometry and western blots to detect toll-like receptor 2 and 4 expression in blood and brain samples

Staphylococcus aureus (S. aureus) is a notorious opportunistic foodborne pathogen and also a common cause of bovine mastitis. It is known to produce many different virulence factors, including various staphylococcal enterotoxins and toxic shock syndrome toxin-1 (TSST-1). The aim of this work was to investigate the regulation, expression, formation and role of S. aureus toxins in relation to food s

Lipases are key components in the mechanisms underlying the persistence and virulence of infections by fungi, and thus also promising triggers for bioresponsive lipid-based liquid crystalline nanoparticles. We here propose a platform in which only a minor component of the formulation is susceptible to cleavage by lipase and where hydrolysis triggers a controlled phase transition within the nanopar

There is a great need to identify new and better prognostic and predictive biomarkers to stratify prostate cancer patients for optimal treatment. The aims of this study were to characterize the expression profile of pre-B cell leukemia homeobox (PBX) transcription factors in prostate cancer with an emphasis on investigating whether PBX3 harbours any prognostic value. The expression profile of PBX3

This article asks what key concerns emerge from the way responsibility is framed in United Nations summit documents on the Sustainable Development Goals (SDGs) adopted in 2015. Our conceptual framework serves to make the study of SDG responsibility more systematic by distinguishing three main senses of responsibility: cause, obligation, and accountability. The framework structures our analysis of
