In this paper we study the evolution of radiative fluxes, flux radii and observable dust masses in protoplanetary discs, in order to understand how these depend on the angular momentum budget and on the assumed heat sources. We use a model that includes the formation and viscous evolution of protoplanetary gas discs, together with the growth and radial drift of the dust component. We find that we

The radius distribution of close-in planets has been observed to have a bimodal distribution, with a dearth of planets around ∼1.5–2.0 R commonly referred to as the ‘radius valley’. The origin of the valley is normally attributed to mass-loss processes such as photoevaporation or core-powered mass loss. Recent work, however, has suggested that the radius valley may instead arise as a consequence o

PLATO (PLAnetary Transits and Oscillations of stars) is ESA’s M3 mission designed to detect and characterise extrasolar planets and perform asteroseismic monitoring of a large number of stars. PLATO will detect small planets (down to <2REarth) around bright stars (<11 mag), including terrestrial planets in the habitable zone of solar-like stars. With the complement of radial velocity observations

Planets form and obtain their compositions from the leftover material present in protoplanetary disks of dust and gas surrounding young stars. The chemical make-up of a disk influences every aspect of planetary composition, including their overall chemical properties, volatile content, atmospheric composition and potential for habitability. This Review discusses our knowledge of the chemical and i

Icy dust particles emerge in star-forming clouds and are subsequently incorporated in protoplanetary disks, where they coagulate into larger pebbles up to millimeter in size. In the disk midplane, ices are shielded from UV radiation, but moderate levels of disk turbulence can lift small particles to the disk surface, where they can be altered, or destroyed. Nevertheless, studies of comets and mete

Light to the Nations is a work created by Yael Bartana which combines different media such as sculpture, VR, and video animation, as well as a learning center.It is a proposal about the attempts, dystopic and utopic, to save humanity in the face of a global catastrophe, whether man-made or caused by nature, which would extinguish any possibility of life on Earth. The work is influenced by post-apo

How can the strategic direction for an organization be supported and communicated if planning, and even strategies, are no longer sufficient options in the age of complexity? In this book it is argued that sense-making communication defines contemporary societies and organizations in a world where narratives and the ability to engage in strategic improvisation are crucial. In the book, new and old

Three channel video and sound installation, 7 min. In her work Overcoming the Future Yael Bartana continues her longstanding inquiry into the human capacity for hope –a prophetic emotion based on past experiences and a prime motor of the political imagination. It is based on Bartana’s interest in the 1920s as a time of intense political, ideological, and social upheavals alive with utopian vision

One channel video and sound installation, 11.35 min.In communities of the diaspora, music can be a powerful tool for collectively preserving memories. Along with storytelling, traditional languages, and dancing, songs can represent a living home for stateless nations.Commissioned by the Jewish Brazilian art space Casa do Povo, Yael Bartana's new work brings together two groups from two different d

This article presents a critical appraisal of the European Union’s (EU) policy process that delivered the Critical Raw Materials Act, 2023–⁠2024. We combine Marxist-Gramscian perspectives on regional blocs and social movement theory on transnational contestation to study a framing contest at two points in the policy process. First, we examined environmental justice frames in technical campaigns to

Beech-wood lignin, derived from the wood of beech trees (genus Fagus), is a lignin-rich biomass with significant potential for valorization. Beech forests are prevalent in temperate regions worldwide, and beech wood possesses desirable properties for various applications, including the construction industry, furniture-making, and pulp production. The oxidative depolymerization of hardwood lignin i

Multimodal integration is currently being discussed as a way to challenge the dominance of automobility by providing attractive alternatives to private car ownership. Combining critical organisation studies with a mobilities perspective, this article maps actions taken towards integrated urban mobility in two Swedish cities over the course of a year and explores how these actions shape the roles a

INTRODUCTION: Ageing right care(fully) is a transnational research study which explores and maps an understanding of the care pathways between ageing in place and hospital at home policy and practices for older adults in Israel, the Netherlands and Sweden. The countries are suited to be compared where they have growing, ageing populations, a focus on healthcare reform and several policies to reduc

PURPOSE: Self-management has increased in recognition in stroke research and rehabilitation along with growing trends of shorter hospital stays and more patient-centred care. Family members are key persons in the self-management process, but their views and experiences of self-management have not been studied in detail. This study aimed to explore family members' understanding of self-management,

Liquid foams are dispersions of closely packed gas bubbles within a liquid phase. They are commonly encountered in daily life, such as in food and cosmetics, and are extensively used in industry due to their unique mechanical properties, exhibiting both solid-like and liquid- like behavior. However, predicting the rheological behavior of liquid foams remains a challenge due to the complex interpla

1. Cytochrome P450 2D (CYP2D) protein is widely expressed across brain regions in human and rodents. We investigated the interactions between tramadol, a clinically used analgesic, and brain CYP2D regulators, by establishing concentration-time curves of tramadol and O-desmethyltramadol (M1) in rat cerebrospinal fluid (CSF) and plasma, as well as by analyzing the analgesia-time course of tramadol.

PURPOSE: The predictive value of excision repair cross-complementation group 1 (ERCC1) gene for survival and response to platinum-based chemotherapy in gastric cancer (GC) remains controversial. We performed a meta-analysis to clarify the precise estimation of the prognostic and predictive effect of ERCC1.METHODS: A systematic literature search was conducted using PubMed, ScienceDirect, Wiley and
