The loss of intertidal foraging habitats at stopover sites is the primary cause of population declines in many migratory shorebirds. However, the absence of high-tide roosts can exacerbate this impact by increasing the energy consumed for alarm flights and longer commutes between foraging and roosting sites, which have been poorly quantified during time-constrained spring stopovers. We monitored a
Ultrasmooth solution-processable quasi-2D perovskite thin films are of critical importance for many optoelectronic devices. In this work, we fabricated an ultrasmooth intermediate-phase free quasi-2D (PEA)2(FA)n−1PbnBr3n+1 perovskite film by using antisolvents with different polarities and boiling points to engineer the crystallization process. The XRD patterns of the perovskite powder showed that

Tunnel evacuation is a challenge that requires a well-prepared strategy and relevant technical andorganizational measures to be successful. The article focuses on the relation between knowledge abouthuman behaviour during an evacuation process and how this knowledge is obtained throughinvestigations after fires and through well-planned experiments. Furthermore, theories are introducedthat explain
A risk indexing method for evaluating safety in railway tunnels has been developed. Firstly, ahierarchical structure with one objective, three sub-objectives, four strategies and ten attributes weredefined. Secondly, attributes were elaborated and developed by means of assessable parametersrelated to tunnel safety. Thirdly, the relative importance of the attributes was analysed and assessed bymean
Regional researchers have extensively debated contradictions of identity-based regionalism and politically initiated regionalisation. Works addressing the spatial imaginaries of state-led regional institutionalisation processes have since emerged. Sometimes neglected, however, is theoretical attention to what I suggest are acts of counter-institutionalisation: attempts to destabilise dominant regi
Trafikverket är enligt Järnvägssäkerhetslag (2022:367), 2 kap., 2 § skyldigt att ha ett säkerhetsstyrningssystem. Säkerhetsstyrningssystemet ska utformas så att de risker som verksamheten kan ge upphov till kan hanteras det vill säga att identifiera, analysera och utvärdera risker som är relevanta för, i detta fall järnvägstunnlar. För att tillgodose kraven i ett praktiskt sammanhang behövs någon
Background: Device-aided therapies (DAT) offer alternatives to oral or transdermal dopaminergic treatments in advanced Parkinson's disease (PD), where they can reduce motor fluctuations and dyskinesia and improve health-related quality of life (HRQoL). The 5-2-1 criteria can be seen as a rough indicator when DAT might be considered, that is, when a patient has daily ≥2 hours off and/or ≥1 hour tro
BACKGROUND: Sub-Saharan Africa is facing a dietary transition with both undernutrition and rising rates of non-communicable diseases. Adopting the reference diet proposed by the EAT-Lancet Commission can reduce both the environmental burden and improve health outcomes. However, whether this diet provides micronutrient adequacy in older adults in low-income settings has not been investigated. This
The construction of heterojunctions between catalysts and cocatalysts is a widely recognized strategy to enhance catalytic activity. The precise placement of cocatalysts is widely understood to optimize charge transfer pathways and catalytic active sites. In this study, we demonstrate that site-selective decoration on an anisotropic catalyst, achieved by modulating solvent polarity and precursor r
The currant bud moth, Euhyponomeutoides albithoracellus, the currant shoot borer, Lampronia capitella and the currant clearwing, Synanthedon tipuliformis, are destructive pests on currants in the Nordic countries, but detailed information about their relative abundance in commercial crop fields is lacking. We used pheromone-baited monitoring traps to analyse the presence and flight period of the t
This paper investigates how regional development policy can combine directionality in addressing societal challenges with subsidiarity, emphasising local participation and engagement. We revisit the theoretical foundations of the ‘entrepreneurial discovery process’ as the main mechanism for local engagement in current European Union regional policy frameworks. In its place, we propose an alternati
Purpose: Statin use has been consistently associated with improved clinical outcomes (especially recurrence) in breast cancer in multiple observational studies backed by compelling preclinical evidence. The strength of this evidence warrants a clinical trial to test the efficacy of statin exposure on breast cancer recurrence. Patients and Methods: The double-blind, phase III, randomized, placebo-c
Left atrial reservoir strain (LASr) offers diagnostic and prognostic value in patients with heart failure. However, LASr may be technically challenging and is not available to all clinical echocardiographers. Since LASr is a consequence of left atrial (LA) stretch during apical descent of the mitral annulus, we hypothesized that a ratio between mitral annular plane systolic excursion (MAPSE) and L
Measurements of the stable carbon isotope ratio in methane (δ13C-CH4) are used in determining the source of CH4 emissions on local, regional, and global scales. To achieve the required level of data comparability for atmospheric monitoring networks, accurate gas reference materials of δ13C-CH4 in air are required with high levels of reproducibility. We describe a method to determine the δ13C-CH4 o
Adsorption onto chromium surfaces during heat treatment (65–68°C) of β-lactoglobulin A and B in phosphate buffer, pH 6.88, was investigated byin situellipsometry. Thermal unfolding andin situheat-induced aggregation under the same conditions were studied by differential scanning calorimetry and dynamic light scattering, respectively. A lag phase was observed for buildup of the thickness of th
Background: Despite the efficacy of SARS-CoV-2 vaccines in reducing mortality and severe cases of COVID-19, a proportion of survivors experience long-term symptoms, known as post-acute sequelae of SARS-CoV-2 infection (PASC). This study investigates the long-term immunological and neurodegenerative effects associated with extracellular vesicles (EVs) in COVID-19 survivors, 15 months after SARS-CoV
