Close stellar encounters play a critical role in shaping planetary systems by perturbing the orbits of minor body populations like the Oort Cloud and the orbits of planets. Using data from the Gaia DR3 catalogue, this work quantifies close stellar encounters, investigating both Sun-star and star-star interactions. Assuming that stars move in straight lines, encounter distances and times were com
Degradation of the hydrological regime is a pressing issue in the Ethiopian Highlands. It is one of the most rapidly degrading landscapes due to its topography and large amounts of annual precipitation. This problem has been exacerbated through anthropogenic influence from land use/land cover (LULC) and climate change. This paper presents the effect on the hydrological cycle caused by these change
In the 1970s young danish people moved into abandoned military barracks in Christianshavn which started a squatting movement that gave rise to the area called Christiania, a semi-autonomous society where internal informal norms are prominent. Pusherstreet in Christiania has always received a lot of attention in the media with its open cannabis market. The market closed multiple times and has resi
Correlations among conserved quantum numbers, such as the net-electric charge, the net-baryon, and the net-strangeness in heavy-ion collisions, are crucial for exploring the QCD phase diagram. In this paper, these correlations are investigated using net-proton number (as a proxy for the net-baryon), net-kaon number (for the net-strangeness), and net-charged particle number in Pb-Pb collisions at =
The molecular mechanisms governing internal fluctuations in intrinsically disordered protein (IDP) assemblies are crucial to the stability and dynamics of both regulated and aberrant toxic cellular aggregates, but remain poorly understood. By comprehensively combining high-resolution quasi-elastic neutron scattering with all-atom molecular dynamics simulations, we probe the motions of β-casein, a
As public libraries in Sweden receive the bulk of their budget from local government funding, which has stayed static or, at best, seen small increases, libraries have been faced with inadequate resources with which to satisfy increasing expectations from users. As few libraries are over-funded in the first place, ways may have to be found to combat this situation. The aim of this Masters thesis i
The European Union Drinking Water Directive aims to protect human health and promote safe water consumption. The 2020 revision, Article 17 in particular, directed member states to provide public access to information on drinking water. This update was a response to citizen initiatives calling for the active participation of end-users in water services and greater transparency from water utilities.
This paper aims to explore how four Bolivian small and medium-sized enterprises’ business has overcome the gaps in reliance on traditional small and medium-sized enterprises’ business models, i.e., to extract and sell raw unrefined natural resources in a local area, and instead make productive use of innovation inputs (technology, higher-educated people) by innovating their business models. We wer
The crossing of aridity thresholds triggers abrupt changes in multiple functional and structural ecosystem attributes across global drylands. While we understand the consequences associated with aridity thresholds, the key factors influencing dryland vegetation resistance when crossing them remain unclear. Here, we used field observations from 58 dryland sites across five continents and satellite
This paper provides insights into the handling of climate change issues related to cultural heritage at different government decision levels dealing with physical planning, and in particular roads. Data are derived from a qualitative analysis of official reports and interviews with local and regional planners in three Swedish regions with contrasting climates. The theoretical lens of Institutional
Solar ultraviolet radiation (UVR) is an important environmental threat for organisms in aquatic systems, but its temporally variable nature makes the understanding of its effects ambiguous. The aim of our study was to assess potential fitness costs associated with fluctuating UVR in the aquatic zooplankter Daphnia magna. We investigated individual survival, reproduction and behaviour when exposed
Given the tremendous phenomenological success of the Standard Model (SM) framework, it becomes increasingly important to understand to what extent its specific structure dynamically emerges from unification principles. In this study, we present a novel anomaly-free supersymmetric (SUSY) Grand Unification model based upon gauge trinification [SU(3)]3 symmetry and a local SU (2) F× U (1) F family sy
Participation of stakeholders at the local level is evolving as a mechanism to address complex environmental problems, not least water pollution. Participation has been used as a tool for the economic and social empowerment of settlements within the catchment of the Korle lagoon in Ghana, particularly residents of the Old Fadama community that live in proximity to the lagoon. Using direct observat
This paper analyses regional public transport planning in Sweden. The aim is to provide an insight into how policy objectives are translated into action and to investigate how public transport measures are evaluated. The analysis is based on interviews with civil servants in five Swedish regions. Cost-benefit analysis is sparsely used (if ever) and the results further indicate that planning and ev
The impedance matching concept is employed in this paper to select the optimum gain of a VSC-HVDC damping controller. The damping controller of the DC link is based on control of active power in proportion to the difference in local frequency at the VSC-HVDC converter stations. To explain impedance matching, the small-disturbance electro-mechanical dynamics of a power system is transformed to an e
Background: Transarterial embolization with particles is a relatively common treatment method in both malignant and benign disorders. Permanent occlusion of the uterine arteries may sometimes be disadvantageous. Purpose: To compare the local tissue effects, possible side effects, and extent of recanalization following uterine artery embolization, using either degradable or non-degradable microsphe
Increasing climate change impacts are a major threat to sustainable urban development, and challenge current governance structures, including actors' responsibilities for dealing with climate variability and extremes. The need for distributed risk governance and citizen engagement is increasingly recognised; however, few empirical studies systematically assess interactions between citizens and mun
While previous research on projectification tends to focus on why processes of projectification emerge and in what contexts, this chapter use the example of European Union (EU) project funding in Swedish local government to analyse and understand how processes of projectification unfold in terms of transformation and adaptation. Key agents in processes of projectification are located and how these
Copper from vehicles disc brakes is one main contributor of the total copper found in the environment. Therefore, the U.S. Environmental Protection Agency (EPA) and the automotive industries started the Copper-Free Brake Initiative. The pad friction material is essentially composed of a binder, fillers, reinforcing fibres and frictional additives. Copper and brass fibres are the most commonly used
Objective To estimate, using numerical calculations, the depth of tissue damage in the uterus following balloon thermal endometrial destruction. Design A parameter, therapeutic depth, was defined. This was the maximum depth into the uterine myometrium, from the uterine cavity, at which a predefined temperature was reached after a certain time and with a constant intracavitary temperature. Setting
