This academic paper explores the current state of regulation in outer space, highlighting the existence of a legal vacuum and the absence of clear norms governing space activities. Existing treaties are often vague and inconclusive in their interpretations. Meanwhile, a new space race is emerging, with commercial entities taking the lead in the West, while global players such as China and Russia sDet går att konstatera att regleringen av rymden befinner sig i en form av rättsligt vakuum. Det saknas idag en tydliga normer för användningen av rymden. Tolkningar av de få traktat som ratificerats av majoritetens av världens länder är vaga och ofta intetsägande. Samtidigt håller en ny rymdkapplöpning på att växa fram. Den här gången har kommersiella aktörer lagt sig i framkant i väst medan glob

Fjärrvärme är en teknologi som har stor potential att bidra till att möjliggöra ett fossilfritt samhälle. För att uppnå denna potential, finns det dock en del förbättringar som måste göras för att förbättra fjärrvärmeverksamheten i stort, minska förlusterna från systemen och därmed öka konkurrenskraften hos fjärrvärme som teknologi. Ett flertal studier har visat att ett sätt att göra detta, och däDistrict Heating is a technology with the potential to enable a fossil-free society. However, to realize this potential, some improvements need to be made in order to improve District Heating operation at large, decrease losses in the systems, and thus increase the competitiveness of District Heating as a technology. Several have shown that a possible solution, to increase the efficiency of Distri

Background: Stunting is one of the most serious and challenging public health problems in Ethiopia, which constitute a significant obstacle to achieving better child health outcomes. This study aimed to assess the prevalence and factors associated with stunting among 6-12 years old children in Humbo district, Southern Ethiopia. Methods: This was a cross-sectional study conducted among 633 children

Objective: To define the role of ultrasound (US) for the assessment of patients with rheumatoid arthritis (RA) in clinical remission, including joint and tendon evaluation. Methods: A multicentre longitudinal study has been promoted by the US Study Group of the Italian Society for Rheumatology. 25 Italian centres participated, enrolling consecutive patients with RA in clinical remission. All patie

Food Waste is a global issue concerning the environment, resources, social justice and economy. Despite being so pressing, around one-third of food produced is discarded worldwide. Meanwhile, food waste is incredibly complicated, requiring collaborations of all stakeholders and various innovations. Too Good To Go (TGTG) utilizes technology to bridge consumers and food business and save food waste

In order to reach the climate targets for the society, with significant lower proportions of CO2 emissions than today, certain actions are required. To be able to decrease the emissions, one alternative is to increase the amount of people who uses public transportation as opposed to using cars. The municipality of Åstorp is one of the districts that emits most CO2 per person and day in Scania, and

Introduction. This article presents the first results from the LibPrepare research project, which explores how the democratic mission of public libraries is understood, imagined and potentially compromised in times of crisis and war rhetoric. The aim is to gain knowledge of the mechanisms, motives and potential implications of enrolling libraries in Swedish national security policy.Method. A themaIntroduction.

OBJECTIVES: To compare sociodemographic, clinical, and suicide-specific characteristics between younger old (aged 65-74) and older old (aged 75+) adults who died by suicide in 2015, and to identify clinically relevant subgroups in the entire study cohort 65+ through cluster analysis.DESIGN: Retrospective cohort study.SETTING: All health care units across Sweden.PARTICIPANTS: Individuals aged 65+ w

Soot particle (black carbon) morphology is of dual interest, both from a health perspective and due to the influence of soot on the global climate. In this study, the mass-mobility relationships, and thus effective densities, of soot agglomerates from three types of soot emitting sources were determined in situ by combining a differential mobility analyzer (DMA) and an aerosol particle mass analyz

We examined oxygen three-isotope ratios of 48 extraterrestrial chromite (EC) grains extracted from mid-Ordovician sediments from two different locations in Sweden, and one location in south-central China. The ages of the sediments (similar to 470 Ma) coincide with the breakup event of the L chondrite parent asteroid. Elemental compositions of the chromite grains are generally consistent with their

Abstract in Chinese 概述 学校教学最重要目的之一是赋予每个孩子同等的教育. 尽管如此, 学校再创造了社会差异. 先前的研究表明,学生的低下社会经济情况背景与自然学科成绩低下有一定联系. 这样, 不少学生在未来就被排斥在社会高端学科的教育和职业之外. 本篇论文在Bourdieu和Bernstein的理论基础上, 以自然学科课堂的社会阶级为中心, 旨在对小 学生所受的教育存在不等现象提供更多方位描述和更深层的分析. 在人种民族学的启发下, 本论文的数据取自瑞典义务小学八年级物理教室里的观察, 记录, 采访和统计调查. 1. 对教室里现象的描述和分析揭示了知识难度的下降. 这一现象的发生通常是因为自然学科的教学所具有的社会历史传统因素, 学生, 老师和教室里的谈话社交之间有无形的默契, 或被称为隐蔽的磋商, (出发点往往是善良的愿望),教室里形成了对所有学生都不利的知识难度的The overall aim of this thesis was to contribute to a more complex and multi-faceted description and analysis of inequalities in education, focusing on social class in the science classroom. Inspired by an ethnographic approach, the data was produced through observations, field notes, interviews, and a questionnaire in a Swedish compulsory school. The students aged fourteen and fifteen, were follo

An honest communication of uncertainty about quantities of interest enhances transparency in scientific assessments. To support this communication, risk assessors should choose appropriate ways to evaluate and characterize epistemic uncertainty. A full treatment of uncertainty requires methods that distinguish aleatory from epistemic uncertainty. Quantitative expressions for epistemic uncertainty

Background: There is an increased risk of suicidality in gambling disorder (GD) and economic hardship is common in the population. Economic hardship itself is a risk factor for suicidality. This study aims to explore the risk of intentional self-harm in GD utilizing social welfare payment (SWP) as a proxy for economic hardship and exploring how economic hardship, gender, criminality, socioeconomic

Even though floral scent is of major importance for pollinator attraction, it is less investigated than other floral traits. Previous studies suggest the importance of joint exploration of olfactory and visual floral cues to understand plant–pollinator interactions. We investigated flower scents in Collinsia heterophylla, a bee-pollinated, annual herb a with mixed-mating system combining self- and
