Bakgrund: Aktivitetsbalans är avgörande för individens välbefinnande, särskilt vid kroniska sjukdomstillstånd som multipel skleros (MS). Aktivitetsbalans beskrivs som en relation mellan önskad och faktisk tidsanvändning inom olika aktiviteter. Fatigue är ett vanligt symtom vid MS och innebär en omfattande hjärntrötthet. Fatigue kan påverka aktivitetsbalans och livskvalitet negativt. Syfte: SyftetBackground: Occupational balance is crucial for an individual's well-being, especially in chronic diseases such as multiple sclerosis (MS). Occupational balance is described as a relationship between desired and actual time spent in different activities. Fatigue is a common symptom in MS and involves extensive brain fatigue. Fatigue can negatively affect occupational balance and quality of lif

Människor i hjälpande roller upplever i stor utsträckning arbetsrelaterad stress, vilket för många resulterar i utbrändhet eller annan psykisk ohälsa. Utvecklandet av självmedkänsla kan enligt forskare ha en skyddande effekt mot bland annat utbrändhet. Korta compassionfokuserade interventioner har i tidigare studier visats bidra till just ökad självmedkänsla och minskad stress. Syftet med den aktuPeople in helping professions experience a great deal of work-related stress, which for many result in burnout or other mental health issues. Developing self-compassion can, according to researchers, have a protective effect against burnout, among other things. Previous studies on brief compassion focused interventions have shown an improvement in self-compassion and reduced stress. The purpose of

I omställningen till fossilfria lösningar har grön vätgas och ammoniak visat på att vara lovande energibärande bränsle. Att tillverka ammoniak med vätgas från förnybara energikällor kräver däremot stora mängder energi, och det är just därför denna studie är relevant. Genom att designa och simulera en ammoniakproduktion baserat på en 200MW elektrolysör med fokus på värmeintegration, har stora vinstGreen ammonia, produced from renewable hydrogen, is emerging as an important energy carrier and decarbonized fertilizer alternative. However, its production is highly energy-intensive, making process efficiency critical to its commercial viability. This study investigates how targeted heat integration can enhance the energy and cost efficiency of green ammonia production based on a 200 MW PEM elec

Per- and polyfluoroalkyl substances (PFAS) include a large group of chemicals that has been used for many decades because of their mechanical and chemical stability. They owe these unique features due to the strong C-F bonds in their molecules. PFAS can be fully or partly fluorinated and the more fluorinated they get, the more persistent they become. They have been used in several industries such

Sverige står inför en betydande utmaning i att minska sina utsläpp av växthusgaser för att nå det nationella klimatmålet om nettnollutsläpp till år 2045. För bygg- och anläggningssektorn innebär detta en omfattande omställning, där alla aktörer i branschen aktivt behöver bidra för att målet ska kunna uppnås. I dagsläget är sektorn en av de större källorna till Sveriges koldioxidutsläpp vilket inneSweden faces a significant challenge in reducing its greenhouse gas emissions in order to reach the national climate goal of net-zero carbon emissions by 2045. For the construction sector, this requires a major transformation where all actors must actively contribute for the goal to be achieved. Currently, the sector is one of the largest contributors to Sweden’s carbon dioxide emissions, making m

This article examines the media construction of Duke Johan of Östergötland (1589–1618), a Swedish prince, through the lens of his recorded gift giving practices. It posits that gifts should be conceptualized as media, shaping the construction of Duke Johan as a ruler and virtuous prince, both in the early seventeenth century and for posterity. By analyzing the remediation of Duke Johan’s gift givi

Autarkic ideology and economic policies were central features of the interwar period in Europe. Despite autarky's connection to geographical concepts such as space, resources and population, its historical impact has been relatively little explored in the literature. In this article, we first present how the concept of 'autarky' conflates two etymological meanings: self-sufficiency and authoritari

Literature on war and the environment has examined a wide range of militarized landscapes, but massive fortification systems such as the Maginot or Siegfried lines, which are symbols of a military trend in vogue during the interwar period, have largely been ignored. These military walls interwove natural and national values and constituted massive landscape interventions, aimed at reinforcing poli

The mobilization of water has been key for the reconfiguration and modernization of the Spanish state. During the Francoist dictatorship (1939–1975), the hydro-social reengineering of Spain was central to Franco's political mission but failed to provide for subnational, regionalist aspirations which subsequently pursued their own agendas for water development. In this paper we examine the (failed)

Bokhandlaren och boråsprofilen John Wold (1863-1942) efterlämnade vid sin död ett värdefullt bibliotek som förvaras hos ordenssällskapet Tempel Riddare Orden i Borås. Innehållet domineras av Wolds två stora intressen: nykterhetsfrågan och ordensväsende. I boken presenteras boksamlingen med ambitionen att i stora drag belysa både dess innehåll och det historiska sammanhang den tillkommit i.

This paper investigates the critical role of workers to enhance the resilience of water supply services in cities at war through analyzing the case of Madrid and the Madrid water company Canales del Lozoya during the Spanish Civil War (1936-1939). We argue that securing the protection of vital urban flows mediated through infrastructures is a key objective of cities under attack. In doing so we co

Soft Magnetic Composites (SMCs) represent a new generation of materials gaining attention for their effective use in electric motors and transformers. The strong magnetic properties, reduced eddy current losses, and flexibility in forming complex 3D shapes. They offer clear advantages over traditional laminated steels, especially in the designs where magnetic behavior is needed in all directions.

The observed imbalance of matter and antimatter in the universe cannot be fully explained by the Standard Model of particle physics. One proposed mechanism to account for this discrepancy is the violation of baryon number B, a process that has yet to be experimentally observed. The HIBEAM/NNBAR project, a proposed two-stage experiment at the European Spallation Source, aims to find evidence of bar
