Digitalizing sexual citizenship: LGBTI+ resistance at digital spaces in pandemic times

Drawing on a digital ethnography of Istanbul Pride events in 2020 and in-depth interviews with LGBTI+ activists from Turkey, this study examines the transformations in the sites and practices of resistance during the COVID-19 pandemic. For the LGBTI+ community in Turkey, whose rights are already threatened by right-wing populist hegemony in politics, the pandemic brought further challenges and lim

Gendered Sustainability: Are Public Spaces Designed for Girls Good for Everyone? Examining Female Participation as a Strategy for Inclusive Public Space

This article examines female participation as a strategy for sustainable development. The increasing interest in female participation as a sustainability strategy on an international scale, underscores the need for critical examinations of this approach. Centring on contemporary Sweden as a prominent site of this development, this article investigates the municipal use of gendered design processes

The sensitivity of pressure-based knock threshold values to alternative fuels : A comparison of methanol vs. gasoline

The heavy-duty industry typically uses a high cetane fuel to power their vehicles, currently typically fossil diesel. Switching to renewable fuels such as methanol requires a major changeover in engine technology. Due to the high octane number of methanol, the diesel engines will have to be replaced by more suitable spark-ignited engines. An accurate knock control system will then be needed to acc

Epigenome-wide association study of DNA methylation in maternal blood leukocytes with BMI in pregnancy and gestational weight gain

Objectives: We aimed to discover CpG sites with differential DNA methylation in peripheral blood leukocytes associated with body mass index (BMI) in pregnancy and gestational weight gain (GWG) in women of European and South Asian ancestry. Furthermore, we aimed to investigate how the identified sites were associated with methylation quantitative trait loci, gene ontology, and cardiometabolic param

The impact of COVID-19 on aflibercept treatment of neovascular AMD in Sweden – data from the Swedish Macula Register

Background: The purpose of the study was to compare the real-world aflibercept treatment and visual outcomes, and to examine the adherence to pandemic guidelines in two groups of patients with treatment-naïve neovascular age-related macular degeneration (nAMD) before and during the first year of the COVID-19 pandemic in Sweden up to the 1-year follow-up. Methods: This is a retrospective observatio

Neighbourhood socioeconomic status and pain among older adults—A cross-sectional study

Background: Pain is associated with falls, disability and a poor quality of life among older adults. It is highly prevalent in many societies, and studies have shown that pain could be preventable or managed more effectively at the population level. However, few studies have investigated who is at higher risk of pain in the general population, which is important for development of effective interv

Apolipoproteins and the risk of giant cell arteritis—a nested case–control study

Background: The etiology of giant cell arteritis (GCA) and its predictors are incompletely understood. Previous studies have indicated reduced risk of future development of GCA in individuals with obesity and/or diabetes mellitus. There is limited information on blood lipids before the onset of GCA. The objective of the study was to investigate the relation between apolipoprotein levels and future

Localization and characterisation of brown rot in two types of acetylated wood

Acetylation is a commercialised chemical wood modification technology that increases the durability of wood against microbial attack. However, the details of how acetylation protects the wood structure from fungal degradation are still unclear. In this study, we tested the hypothesis that the resistance against microbial attack depends on the localisation of acetylation within the cell wall. The m

The geopolitics and challenges of current issues in tourism

The tourism industry, destinations, and the wider tourism community and stakeholders face several significant short and long-term challenges that will substantially affect the future direction of tourism. Issues of social, economic, and environmental change are further complicated by current geopolitical conflicts and competition. These issues raise important questions with respect to the role of

Bone mineral density after exercise training in patients with chronic kidney disease stages 3 to 5 : a sub-study of RENEXC—a randomized controlled trial

Background. We evaluated the effects of 12 months of exercise training on bone mineral density (BMD) in patients with chronic kidney disease (CKD) stages 3–5 not on kidney replacement therapy (KRT). Methods. A total of 151 patients were randomized to 12 months of either balance or strength training, both together with endurance training. Some 112 patients completed and 107 (69 men, 38 women) were

Inverse design of high-dimensional quantum optical circuits in a complex medium

Programmable optical circuits are an important tool in developing quantum technologies such as transceivers for quantum communication and integrated photonic chips for quantum information processing. Maintaining precise control over every individual component becomes challenging at large scales, leading to a reduction in the quality of operations performed. In parallel, minor imperfections in circ

Transthoracic impedance variability to assess quality of chest compression in out-of-hospital cardiac arrest

Background: Chest compression is a lifesaving intervention in out-of-hospital cardiac arrest (OHCA), but the optimal metrics to assess its quality have yet to be identified. The objective of this study was to investigate whether a new parameter, that is, the variability of the chest compression-generated transthoracic impedance (TTI), namely ImpCC, which measures the consistency of the chest compr

Integrability of a Globally Coupled Complex Riccati Array : Quadratic Integrate-and-Fire Neurons, Phase Oscillators, and All in between

We present an exact dimensionality reduction for dynamics of an arbitrary array of globally coupled complex-valued Riccati equations. It generalizes the Watanabe-Strogatz theory [Integrability of a globally coupled oscillator array, Phys. Rev. Lett. 70, 2391 (1993).PRLTAO0031-900710.1103/PhysRevLett.70.2391] for sinusoidally coupled phase oscillators and seamlessly includes quadratic integrate-and

Ectomycorrhizal fungi are more sensitive to high soil nitrogen levels in forests exposed to nitrogen deposition

Ectomycorrhizal fungi are essential for nitrogen (N) cycling in many temperate forests and responsive to anthropogenic N addition, which generally decreases host carbon (C) allocation to the fungi. In the boreal region, however, ectomycorrhizal fungal biomass has been found to correlate positively with soil N availability. Still, responses to anthropogenic N input, for instance through atmospheric

Gastrointestinal symptoms in patients with postural orthostatic tachycardia syndrome in relation to hemodynamic findings and immunological factors

Gastrointestinal (GI) symptoms are common in postural orthostatic tachycardia syndrome (POTS). We aimed to explore the prevalence and severity of GI symptoms in POTS, and to investigate immunological factors, hemodynamic findings, and their possible association with GI symptoms in POTS. Forty-three patients (93% female, median age 30.6 (26.0-41.0) years), previously diagnosed with POTS and 74 heal

Event structure, force dynamics and verb semantics

This article presents a cognitive model of event structure that can be used to explain several features of the semantics of verbs. The model consists of four basic components: agent, patient, force vector and result vector. Each component is described in terms of the theory of conceptual spaces. The force vector is the cause of the result vector. Unlike other event models both the cause and the ef

Afterload system design for functional donor heart assessment

Heart transplantation is a life-saving procedure for patients with end-stage heart failure. However, conservative acceptance criteria result in most donated hearts being discarded. Enabling clinicians to assess heart function after organ procurement can pave the way for the safe use of hearts that are currently rejected. This thesis focuses on improving techniques for the direct, controlled assess
