Seasonal migration patterns of Siberian Rubythroat (Calliope calliope) facing the Qinghai–Tibet Plateau

Background: Small songbirds respond and adapt to various geographical barriers during their annual migration. Global flyways reveal the diverse migration strategies in response to different geographical barriers, among which are high-elevation plateaus. However, few studies have been focused on the largest and highest plateau in the world, the Qinghai–Tibet Plateau (QTP) which poses a significant

The paradox of workplace violence in the intensive care unit : a focus group study

Background: Conflicts with patients and relatives occur frequently in intensive care units (ICUs), driven by factors that are intensified by critical illness and its treatments. A majority of ICU healthcare professionals have experienced verbal and/or physical violence. There is a need to understand how healthcare professionals in ICUs experience and manage this workplace violence. Methods: A qual

Extreme mitochondrial reduction in a novel group of free-living metamonads

Metamonads are a diverse group of heterotrophic microbial eukaryotes adapted to living in hypoxic environments. All metamonads but one harbour metabolically altered ‘mitochondrion-related organelles’ (MROs) with reduced functions, however the degree of reduction varies. Here, we generate high-quality draft genomes, transcriptomes, and predicted proteomes for five recently discovered free-living me

Management of acute uncomplicated diverticulitis and adherence to current guidelines—a multicentre SNAPSHOT study

Purpose: To explore whether previous participation in clinical studies increases adherence to management guidelines in acute uncomplicated diverticulitis (AUD). Methods: This retrospective cohort study was designed to give a SNAPSHOT of the management of AUD at six hospitals, three of which had participated in the AVOD trial comparing antibiotic versus non-antibiotic treatment of AUD. Patients wit

Flight-intensive practices and wellbeing: current evidence and future research

This article draws on social practice theory and wellbeing perspectives to outline a research framework for the study of flight-intensive practices. The framework is then used to discuss, through a non-systematic review, the social science air travel literature and to propose avenues for future research. We study both the work and leisure domains, with sub-cases for travel in academia and visiting

Enhancing metabolic efficiency via novel constitutive promoters to produce protocatechuic acid in Escherichia coli

Abstract: The antioxidant molecule protocatechuic acid (PCA) can also serve as a precursor for polymer building blocks. PCA can be produced in Escherichia coli overexpressing 3-dehydroshikimate dehydratase (DSD), an enzyme that catalyses the transformation of 3-dehydroshikimate to PCA. Nevertheless, optimizing the expression rate of recombinant enzymes is a key factor in metabolic engineering when

The Influence of Narrative Specificity and Voice Quality when Listening to Audio Descriptions: a Comparison of the Sighted and the Blind

Audio description (AD) serves as a vital means to make visual media accessible to non-sighted and visually impaired audiences. This study systematically investigates the impact of narrative specificity and voice quality on imageability and comprehension in both sighted and non-sighted populations. Twenty non-sighted participants, including congenitally blind individuals and those who lost their si

The rate of W chromosome degeneration across multiple avian neo-sex chromosomes

When sex chromosomes evolve recombination suppression, the sex-limited chromosome (Y/W) commonly degenerate by losing functional genes. The rate of Y/W degeneration is believed to slow down over time as the most essential genes are maintained by purifying selection, but supporting data are scarce especially for ZW systems. Here, we study W degeneration in Sylvioidea songbirds where multiple autoso

Exposure to source-specific air pollution in residential areas and its association with dementia incidence : a cohort study in Northern Sweden

The aim of this study was to investigate the relationship between source-specific ambient particulate air pollution concentrations and the incidence of dementia. The study encompassed 70,057 participants from the Västerbotten intervention program cohort in Northern Sweden with a median age of 40 years at baseline. High-resolution dispersion models were employed to estimate source-specific particul

Response surface methodology to optimize membrane cleaning in nanofiltration of kraft black liquor

Better understanding of membrane fouling and cleaning can help implementation of membrane filtration processes in the pulp and paper industry. The aim of this study was to optimize membrane cleaning in the nanofiltration of kraft black liquor ultrafiltered permeate for the recovery of lignin. This work wants to assess whether the cleaning process removes the main foulants; as well as the economic

Making warming worlds : Future making between climate politics and science – The case of the Structured Expert Dialogue

The Long-Term Global Goal (LTGG) is the focal point for addressing future climate change. This paper explores a specific institutional context: the Structured Expert Dialogue (SED) of the UN Framework Convention on Climate Change (UNFCCC). Set up as a platform for interaction between experts and UN negotiators, the SED is a site where scientific information about the LTGG and net-zero was translat

A multidomain PARP14 construct suitable for bacterial expression

Poly-ADP-ribose polymerase-14 (PARP14) can modify proteins and nucleic acids by the reversible addition of a single ADP-ribose molecule. Aberrant PARP14 functions have been related to cancer and inflammation, and its domains are involved in processes related to viral infection. Previous research indicates that PARP14 functions might be mediated via a multitude of target proteins. In vitro studies

Weimarrepubliken - hisnande, bruten : Recension av Harald Jähner: Vertigo: The Rise and Fall of Weimer Germany 1918-1933

Weimarrepubliken, den demokratiska parentesen mellan Andra och Tredje tyska riket, representerar en av de politiskt mest dramatiska och kulturellt mest dynamiska episoderna i den europeiska 1900-talshistorien. Republiken kunde, om den fått leva, ha lett världshistorien i helt andra och ljusare banor. Mycket har med fog genom åren skrivits om den och nu har ett stort arbete sett dagens ljus med den

Exogenous Metal Cations in the Synthesis of CsPbBr3 Nanocrystals and Their Interplay with Tertiary Amines

Current syntheses of CsPbBr3 halide perovskite nanocrystals (NCs) rely on overstoichiometric amounts of Pb2+ precursors, resulting in unreacted lead ions at the end of the process. In our synthesis scheme of CsPbBr3 NCs, we replaced excess Pb2+ with different exogenous metal cations (M) and investigated their effect on the synthesis products. These cations can be divided into two groups: group 1 d
