This article focuses on the analysis of a direct air-cooled rotor winding of a wound field synchronous machine, the innovation of which lies in the increase in the internal cooling surface, the cooling of the winding compared to the conventional inter-pole cooling, and the development of a CHT evaluation model accordingly. Conjugate heat transfer (CHT) analysis is used to explore the cooling effic
AIMS: The VALIDATE-SWEDEHEART trial was a registry-based randomized trial comparing bivalirudin and heparin in patients with acute myocardial infarction undergoing percutaneous coronary intervention. It showed no differences in mortality at 30 or 180 days. This study examines how well the trial population results may generalize to the population of all screened patients with fulfilled inclusion cr
Magnesium (Mg) is a metallic material with a great range of potential applications. It can be used as the lightest structure material in automotive and aviation sectors, medical implants, hydrogen storge, etc. In such applications, oxidation and corrosion reactions play a critical role in the effectiveness of use. Therefore, deeper understanding of the fundamental mechanisms of oxidation and corro
Research on the rhythmic communication (RC) of nonhuman animals is undergoing a period of great effervescence and expansion. Here, we synthesize this rapidly growing literature with the aim of mapping RC forms and usage contexts in an unprecedented diversity of taxa, spanning insects, fish, frogs, birds and mammals. We see this as a first large-scale effort toward charting the functional and struc
This study is an explorative examination of changes in employment, revenue, and firm structure for low, mid, and high-skill firms in urban and rural areas in Sweden from 2007 to 2019, using skill groups based on education levels. For employment in Sweden in general, we find evidence of job upgrading. In the city of Stockholm we also document job polarization in the sense that employment in both lo
Globally, 3 billion people rely on solid biomass fuel for their everyday cooking, most often using inefficient cooking practices, leading to high exposure levels of household air pollution. This is subsequently associated with negative health and climate impact. Further, the inefficient use of biomass fuels applies pressure on natural forests, resulting in deforestation, loss of biodiversity, and
Environmental variation has long been considered a key driver of evolutionary change, predicted to shape different strategies, such as genetic specialization, plasticity, or bet-hedging to maintain fitness. However, little evidence is available with regards to how the periodicity of stressors may impact fitness across generations. To address this gap, I conducted a reciprocal split-brood experimen
Idrott och hälsa är ett ämne där den största delen av innehållet förmedlas muntligt, vilket gör talspråket till en avgörande faktor för elevernas förståelse och delaktighet. Den muntliga kommunikationens betydelse är särskilt relevant i klasser med stor språklig mångfald där elever med svenska som andraspråk kan ha svårt att följa instruktioner och delta fullt ut om de inte förstår det talade språ
Background: Butaro Cancer Center of Excellence (BCCOE) was founded to serve Rwanda’s rural low-income population, providing subsidized cancer diagnosis and treatment with transport stipends for the lowest-income patients. We examined whether travel distance to BCCOE was associated with advanced-stage diagnoses and treatment completion. Methods: We conducted a retrospective cohort study using medic
The origin and evolution of sponges have attracted interest, not only because they are among the most basal metazoans, but also because they act as important ecological engineers in the ocean. Previous research suggested that sponge groups diversified quickly during the Cambrian Series 2, while Terreneuvian sponge fossils are conspicuously rare and poorly substantiated. Yet, an increasing number o
Aim: There is a knowledge gap regarding which patients with anorectal malformations (ARMs) are at highest risk of anorectal prolapse (AP), and which risk factors predispose to AP in ARM. The aims of the study were to define the frequency of AP after ARM reconstruction, and explore risk factors. Method: Data from the ARM-Net registry inserted between 2007 and 2023 were used. Inclusion criteria were
Background: Complementary prognostic markers are needed in thymic epithelial tumors (TETs) to aid patient stratification and determine the most appropriate follow-up strategies. This study aimed to assess the diagnostic and prognostic relevance of blood-based inflammatory markers in a large cohort of surgically treated TET patients. Material and Methods: A total of 743 TET patients who underwent s
Rhythmic patterning is a widespread structural trait of animal (including human) communication. Concomitantly, a key role of communication is to convey and/or induce emotion. The expression and modulation of emotion is also hypothesized to be a key mechanism for the evolution of rhythmic synchronization in humans. Despite the centrality of both rhythm and emotion to human and nonhuman communicatio
Rhythmicity is a composite competence that spans perceptual, motor, and socio-cognitive abilities. This is highly salient when adopting a developmental perspective, as we do in this chapter that reviews data from humans and other singing primate taxa with a close (gibbons) or remote (indri lemurs) phylogenetic relatedness to our species. The findings we review show that rhythmicity develops as an
Animals communicate with a staggering diversity of rhythmic signals, yet behind all this diversity lies a small number of ethological mechanisms. In this chapter, we provide a quick review of how animal produce rhythmic signals based on these mechanisms, which span tremulation, percussion, bodily displays, stridulation, tymbalation, aerodynamic sound production (including vocalisation), as well as
The global increase in childhood overweight and obesity presents significant public health concerns due to its long-term health implications. Emerging evidence suggests that exposure to endocrine disrupting chemicals, such as per- and polyfluoroalkylated substances (PFAS), may be obesogenic and contribute to adiposity. This study aimed to investigate the association between prenatal PFAS exposure
