Kan proteiner visa vägen till bättre plaståtervinning och en renare värld? Vissa typer av proteiner(enzymer) har under de senaste åren visat prov på nedbrytning av plast och kan därför bli en ny och hållbar metod för plaståtervinning. Mest framgångsrikt är en typ av enzymer som kallas cutinas som kan effektivt bryta ner PET, som bland annat finns i PET-flaskor. Nu visar forskning på att användninPolyolefins make up the majority of all plastics produced and can be found in a range of applications. Simultaneously, 60% of all plastics are not being recycled, and consequently are accumulating in the environment where it poses serious threats to both the environment, human health, and economies. Current attempts to address the problem have had limited success. An emerging solution is biodegrad

Cyklometallering är en kemisk reaktion där en metall och en organisk molekyl (ligand) och tillsammans bildar en ringstruktur, vilket gör det möjligt att bryta annars tröga bindningar (som kol-väte-bindningar) och skapa stabila metallorganiska föreningar med en ny metall-kol-bindning. Dessa typer av reaktioner används inom flera områden såsom framställning av läkemedel och katalys av kemiska procesCyclometallation is an important reaction and is essential in organometallic chemistry for the synthesis of stable metal-ligand frameworks and in the development of functional catalytic compounds. Although extensively studied, challenges remain in achieving selective C-H bond activation without the formation of unwanted side products. In this study, a PCP pincer ligand and subsequent cyclopalladat

Introduction: Person-centred care is being implemented in healthcare to facilitate co-created care and patients' participation in their own care. This is a new practice, also among radiographers. The aim of the study was to explore radiographers' perceptions of the framework of person-centred care and its performance in radiography.Methods: Phenomenography was the study design. Focus group discuss

Ett välkänt problem med dagens suicidriskbedömningar är att de är så osäkra. Det finns tyvärr inget riskbedömningsverktyg som kan avgöra om patienter faktiskt kommer att avsluta sina liv om de inte får vård (Runesson et al, 2017). Ett annat problem, vilket inte uppmärksammats i suicidlitteraturen men som är i fokus i denna text, är att riskbedömningar missgynnar vissa grupper. Forskning om artific

En av orsakerna till att näringslivets olika parter har svårt att se sin egen relevans och styrka i det brottsförebyggande arbetet handlar inte bara om den specifika verktygslåda de har till sitt förfogande, utan om det sätt både de och vi har kommit att tänka på och förstå vad som definierar det brottsförebyggande. Med andra ord verkar en huvudorsak till att många företagare uppfattar sig som "pr

BACKGROUND: Accurate risk stratification in older adults presenting to the emergency department (ED) is essential but challenging due to atypical presentations and age-related physiological changes. While vital signs are central to triage, their predictive value for short-term mortality in this population remains unclear. This study aimed to explore the association between initial vital signs and

Abstract:Concomitant chronic widespread pain (CWP) in patients with rheumatoid arthritis (RA) continues to be a problem despite modern pharmacological treatment. The overall aim was to investigate factors involved in chronic widespread pain in rheumatoid arthritis.Study I, compared patients with early RA (duration ≤12 months), in a tight control cohort, with conventionally managed patients. The pa

Chemical exchange saturation transfer MRI is a promising magnetization transfer (MT) imaging technique that utilizes, by radiofrequency irradiation, selective saturation of exchangeable protons in solutes. This enables the indirect detection of the solutes through the water signal after saturation transfer by chemical exchange, cross-relaxation, or the combination of the two. Typically, the water-

Detta examensarbete behandlar cellons roll under barocken och går igenom den pågående diskussionen kring terminologi och spelstil. Tyngdpunkten ligger på en analys och kritisk granskning av Michel Corrette’s Méthode pour apprendre le violoncelle, Op. 24, samt ett praktiskt utforskande av Correttes principer som resulterade i en inspelning av en sonat för två celli av Corrette. Genom att experimentThis thesis explores the role of the cello in the Baroque period and examines the ongoing discussion surrounding terminology and performance style. The main focus is a critical analysis and review of Michel Corrette’s Méthode pour apprendre le violoncelle, Op. 24, along with a practical application of Corrette’s principles, which culminated in a recording of a sonata for two cellos by Corrette. By

Det är ett ofta återkommande problem för hornister att utöka sitt register, i detta fall höjdregistret. Det finns också en uppsjö av olika beskrivna övningsmetoder med detta syfte. Denna uppsats diskuterar, ur ett autoetnografiskt perspektiv, utökning av höjdregistret med hjälp av Brophys och Lejonclous övningsmetoder. Övningarna inkorporerades i den dagliga övningsrutinen och dokumenterades både An often recurring problem for horn players is to expand their register, in this case the high register. Therefore, it is no wonder that there are a great number of different methods described for this purpose. This thesis discusses, from an autoethnographic perspective, the process of expanding the high register by using Brophy´s and Lejonclou´s practice methods. The exercises were incorporated i

I detta arbete redogör jag för brister och tillgångar i psalmutövande och psalmskrivande, i tider med ny psalmbok på gång. Jag har gått igenom hur tidigare psalmbokskommitté tänkte och gjorde samt intervjuade sekreterare i dåvarande grupp, Per-Olof Nisser. Jag har med dessa glasögon gått igenom nyskrivna verk och dess möjligheter och svårigheter att kunna bli del av en framtida psalmbok. Det jag hIn this master’s thesis, I will go through the strengths and weaknesses in contemporary hymn writing, in times when the Church of Sweden is in the process of revising their hymn book. I have compared this process with the previous process, what the committees thought and did and interviewed the secretary of the previous committee, Per-Olof Nisser. With this knowledge I have analyzed some new made

This thesis will examine the issue of how stalking manifests in Greenland, with a particular focus on the country’s unique rural, social, and cultural context. Despite the recent legislative proposal (L112) that is to criminalize stalking and identity theft in Greenland, the issue of stalking remains under-researched and underrepresented, especially in rural and remote settlements, where support s

White dwarf stars represent the last evolutionary stage of most stars in the Universe. As many of half of these stars are known to have metals in their atmospheres, that must have entered the atmosphere recently. Some also have observable debris discs, hinting that remnant exoplanets provide an important puzzle piece. However, we do not know the full extent of their role, as it is very hard to obs

This thesis examines how transnational mobility shapes the relationship between the sense of national belonging, European affiliation, and openness towards “others” among Polish students who have studied abroad. Based on 308 survey responses, it explores how living and studying away from one’s home country influences self-perception and impacts intergroup attitudes, applying Social Identity Theo

The growing number of offshore wind farms being constructed in the North Sea raises important questions about their potential ecological impact on marine communities. Monitoring these effects requires tools that can accurately describe biodiversity, not just in terms of species presence, but also their relative abundance. Environmental DNA analysis is a promising approach for this purpose, but the
