Rotating swings are found in many different versions in parks around the world. They are beautiful examples of the equivalence between gravitational and inertial mass: empty swings and swings with heavy adults hang at the same angle to the vertical. However, sometimes one can notice empty swings moving in a different pattern in an outdoor ride, where wind can induce additional motion, sideways or

This study revives a heavily debated relationship between government debt accumulation and economic growth. Although indebtedness levels stay high, current economic growth forecasts seem optimistic not only in the euro area but in other advanced countries, as well. 24 advanced OECD economies are investigated to understand if financial outcomes are detrimental to the real economic variables in the

Objectives: Menstrual migraine (MM) is a debilitating neurological disorder triggered by fluctuations in ovarian hormones, particularly estrogen. While the calcitonin gene-related peptide (CGRP) system is central to migraine pathophysiology, the molecular mechanisms linking hormonal changes to CGRP signaling remain unclear. This study investigates how sex hormones regulate CGRP-related gene expres

Sweden’s art and music schools (SAMS), established in the 1940s, provideaffordable extra-curricular instrumental and singing teaching for everychild, regardless of their family’s financial situation. Tuition is heavilysubsidised, with families contributing only some 7% of the cost. WhileSAMS traditionally offer one-to-one instruction, a recent governmentalreport (2016) advocates for group teaching

The investigation of carbon monoxide (CO) adsorption on the unreconstructed Ir(100)-(1 × 1) surface under ultra-high vacuum (UHV) conditions is studied with scanning tunneling microscopy (STM), low-energy electron diffraction (LEED), and high-resolution core-level spectroscopy (HRCLS). At a low coverage of 0.5 ML (monolayer), CO molecules adopt a previously documented c(2 × 2) structure, having CO

Arabinoxylan (AX) with varying arabinose to xylose (A/X) ratios of 0.85, 0.57 and 0.39 was extracted from wheat bran, and the conformations of the AX polysaccharides dispersed in water were investigated using small-angle X-ray scattering. The persistence length (Lp) and the conformation statistics (expressed by the Flory exponent v or the mass fractal) of the AX varied with their A/X ratios. The L

In this paper we suggest that attention to the social practice of prepping, with its particular focus on how people navigate uncertain and potentially disastrous futures, can help broaden our understanding of forced migration. We argue that the emerging literature on doomsday prepping provides a particularly interesting vantage point from which to study the relationship between forced migration, t

Användningen av artificiell intelligens ökar inom många områden i det samtida samhället, inklusive datorsynssystem som bygger på maskininlärning och artificiella neuronnätverk. Dessa system omformar handlingsmöjligheter och beskrivs ofta som ”svarta lådor” som utmanar etablerade former av vetenskaplig förståelse och teknisk kontroll. Det är därför viktigt att förstå de aktiviteter genom vilka sådaThe uses of artificial intelligence are increasing across many areas of contemporary society, including computer vision systems involving machine learning and artificial neural networks. These systems rearrange action possibilities and are often described as “black boxes” that challenge conventional modes of scientific understanding and engineering control. It is important to understand the activi

In an era where online interactions increasingly shape social dynamics, the pervasive issue of cyberbullying poses a significant threat to the well-being of individuals, particularly among vulnerable groups. Despite extensive research on text-based cyberbullying detection, the rise of visual content on social media platforms necessitates new approaches to address cyberbullying using images. This d

The Re-Os (rhenium-osmium) chronometer applied to molybdenite (MoS2) is now demonstrated to be remarkably robust, surviving intense deformation and high-grade thermal metamorphism. Successful dating of molybdenite is dependent on proper preparation of the mineral separate and analysis of a critical quantity of molybdenite, unique to each sample, such that recognized spatial decoupling of 187Re par

A major target of the Marxist critique of “post-theory”—a broad term encompassing post-structuralism, post-Marxism, and postcolonial theory—has been its notorious deconstruction of the subject. The affirmation of marginal, excluded, and deviant subject positions within the same corpus has been noted less frequently. To recalibrate the Marxist critique of post-theory to also encompass its affirmati

The 7Be(d, α)5Li and 7Be(d, p)8Be*(p 7Li) reactions are studied at 5 MeV/u in the context of the cosmological lithium problem. This work aims to probe the contribution of 7Be destruction mechanisms, particularly through channels that populate intermediate unbound states of 5Li and 8Be. The contribution of 7Be(d, α)5Li(p α) reaction is separated from the 7Be(d, p)8Be*(2α) reaction. The 7Be(d, p)8Be

In the mid- to late 1970s, the Swedish economy faced a profit squeeze which threatened to hamper investments and the creation of jobs. This engendered a massive debate in the media and among economists and policymakers. This article investigates what I call ‘the politics of profits, the debates around the role of corporate profits in a democratic capitalist society and economy and the policy measu

Background: The eco-corona, consisting of environmental biomolecules formed around engineered nanomaterials (ENMs) when released to the environment, has gained increasing focus in the scientific literature and its role for ENM fate and toxicity is now widely acknowledged. The European chemicals legislation, REACH, entails reporting requirements when it comes to the transformation of nanoforms. Gui
