BackgroundThe use of single-use laryngeal masks has increased in recent decades; yet, their climate and environmental impacts remain poorly understood. This study aimed to compare the climate impacts of reusable and single-use laryngeal masks.MethodsWe conducted a life cycle assessment that compared the reusable Ambu Aura40 with the single-use Ambu AuraStraight and Intersurgical Igel+ laryngeal ma

On 29 October 2023, Turkey will celebrate the centenary of the proclamation of the Republic. This promises to be a spectacular and carefully politized event, in line with earlier celebrations of National Days and other “defining moments” in the state’s autobiography (such as the conquest of Istanbul – celebrated in ever-aggrandising scale under the AKP-government). In official historiography, the

IntroductionThis study investigates the relationship between religiosity, general sexual attitudes, and public perceptions of sex work in Italy, a country where religious traditions play a significant role in shaping societal values. We aim to understand how various aspects of religiosity, such as the importance of God, religious service attendance, and prayer frequency, influence attitudes toward

The Hjortspring boat is the only intact example of a prehistoric sewn plank boat ever found in Scandinavia. Built from lime wood planks lashed together with cordage, the boat represents the maritime technology used by some of Northern Europe’s earliest seafarers. This article reports new analysis of the cordage and caulking material used in the construction of the Hjortspring boat. We provide the

Each spring, billions of Bogong moths escape hot conditions across southeast Australia by migrating up to 1,000 km to a place that they have never previously visited—a limited number of cool caves in the Australian Alps, historically used for aestivating over summer1,2. At the beginning of autumn, the same individuals make a return migration to their breeding grounds to reproduce and die. Here we

Sri Lankan Muslims are sometimes referred to as Moors, and they are predominantly Sunni while some Muslims are part of some smaller Shia communities such as Memons and Bhoras. Despite playing no role in the civil war in Sri Lanka fought between Tamil militant groups and the Sri Lankan government, Muslims were highly affected by the war, and there was a rise of ethnic tensions in the country follow

Chemical weathering of silicate rocks redistributes major, minor and trace elements through coupled dissolution–precipitation reactions. These weathering processes drive shifts in ocean acid–base chemistry, modulating atmospheric carbon dioxide levels and providing a stabilizing feedback in the carbon cycle. Silicate weathering occurs in both terrestrial and marine environments, releasing (‘forwar

In this article, we argue for the value of student podcasts for fostering dialogue around questions of poetry and sustainable futures in an English as a foreign language context. Our research draws on our experiences of inviting student teachers to create their own podcasts on a recently published poem about nature or the Anthropocene, or both, in our first-year literature course for those studyin

Ensuring high vaccination coverage is vital, particularly during a pandemic. While pre-booked appointment letters have shown promise in vaccination campaigns, their effectiveness in specific sociodemographic groups remains to be explored. Our study evaluated the effect of pre-booked appointment letters on COVID-19 vaccine uptake within different sociodemographic groups using a quasi-experimental m

This study assesses the feasibility of extracting high-quality DNA from blood samples stored at – 20 °C for up to 21 years under suboptimal conditions. It addresses sample mishandling in research, where many samples lack proper biobank protocols. Prior studies focused on short-term storage and controlled conditions, highlighting the negative effects of freeze–thaw cycles. This study evaluates whet

The article discusses the development and application of the so-called “stigma engagement strategy (SES)” in interviews with stigmatized study populations, drawing on an interview study with Swedish men who have paid for sex. SES is a qualitative methodological approach that utilizes external sources of stigmatizing narratives, such as newspaper articles and columns, as textual probes within inter

This chapter examines how people associate various sex work activities with the exchange of sexual services for payment. It considers both in-person activities, such as sexual intercourse, oral sex, erotic massage, and dancing, as well as remote, digitally mediated activities like webcamming and the production of pornographic videos and photos. Drawing on an original US survey of adults (n = 1,024

The idea that sex-differences in selection drive the evolution of suppressed recombination between sex chromosomes is well-developed in population genetics. Yet, despite a now classic body of theory, empirical evidence that sexually antagonistic (SA) selection drives the evolution of recombination arrest remains equivocal and alternative hypotheses underdeveloped. Here, we investigate whether the

BACKGROUND: The implementation of COVID-19 vaccination among older persons at nursing homes has lowered the infection-associated mortality considerably, but emerging virus variants and decline in vaccine-induced immunity over time necessitate examination of future booster dosing strategies. The overall aim of this study was to assess vaccine protection against COVID-19 mortality in relation to tim

This paper provides a comprehensive overview of how emblems wereused on Swedish royal medals and commemorative coins duringthe seventeenth century, a period marked by the rise of the SwedishEmpire. Focusing on numismatic objects that thematize royalsuccession and coronations, it focuses on how emblems were utilizedacross multiple monarchs, touching on the origin of the emblems andhow the use of em
