Proenkephalin (PENK) is assumed to be freely filtered by the glomerulus, thus potentially useful for estimating glomerular filtration rate (eGFR). Recently developed eGFR-equation based on PENK and creatinine has not been validated against existing cystatin C-based equations. This study aimed to test the hypothesis of free filtration of PENK. Also, the PENK-creatinine based eGFR-equation was valid

A ferrous complex bearing tris(carbene)borate ligands with imidazol-2-ylidene donors has been characterized by experimental and computational methods. Despite the pronounced destabilization of metal centered states by the exceptionally σ-donating ligand, the high-energy 3MLCT state of [Fe(ii)(phtmeimb)2] is rapidly deactivated by the barrierless conversion to the 3MC state.

I takt med att andelen variabel förnybar energi ökar i det svenska elsystemet krävs nya lösningar för att hantera utmaningar kopplade till intermittens, nätstabilitet och ekonomisk lönsamhet. Batterilagringssystem (BESS) lyfts fram som en av de mest lovande lösningarna för att möta dessa utmaningar. Detta examensarbete undersöker den tekniska och ekonomiska genomförbarheten av att integrera BESS mAs the share of variable renewable energy (VRE) increases in the Swedish electricity system, new solutions are needed to address challenges related to intermittency, grid stability, and economic viability. Battery energy storage systems (BESS) have been identified as one of the most promising solutions to meet these challenges. This master’s thesis investigates the technical and economic feasibili

Drönare och andra eldrivna luftfordon gör allt större inslag i dagens samhälle, med unik potential att forma framtiden. För en effektivare drift kan kontraroterande propellerpar användas. Interaktionen mellan propellrarna är däremot komplex, men här visas det tack vare optimering att en verkningsgrad högre än för två separata propellrar kan uppnås – du kan båda äta kakan, ha den kvar och få en smuContra rotating propellers (CRP) exhibit several benefits compared to a traditional single-propeller setup. It has for example a high thrust-to-area ratio and offsetting torque is minimized. Accordingly it has several applications, one of them being electrical vertical take-off and landing (eVTOL) aircraft. The present thesis sets out to optimize the contra rotating propeller setup, both from a mo

The purpose of this thesis’ topic is to investigate regular usage and relations between the development led archaeology and the archival institutions of Skåne region in southern Sweden, specifically to highlight how archives might act as reliable sources of information to aid development led archaeology in Skåne region. The research questions touch upon the following topics: what categories of sou

The National Archives of Sweden have been given the task of standardising the management of electronic records in the public sector so as to ensure long-term storage and readability of these records in electronic archives. Standardisation is a powerful tool which eases transferability and prevents obsolescence. International organisations, including the EU, have long been producing and managing st

The Swedish labour movement archives are an early example of community archives. Despite this, they have never been examined as such before. This study aims to examine how the labour movement archives functions as community archives, and how that function has changed over time. Since the first labour movement archive opened in Stockholm in 1903, and the subsequent archives opened in smaller Swedis

This thesis examines how archival educators perceive their professional role and practice. The thesis focuses on three main themes: education, challenges and development. The question of whether the education and competence of the archival educators has an impact on the archival educational practice, or the professional status of the professional role is addressed, as well as what aspects or situa

The introduction and subsequent development of the railroad during the 19th century is a fundamental part of world history, due to it being a key player in the shaping of modern society. Therefore, the history of the railroad and its importance is a subject well suited for museums with several museums dedicated to railroad history appearing around the world. Within these museums, trains become int

The Swedish Museum field has seen an emergence of new private actors who use the term museum, but whose operations often differ from the general museum sector, especially by moving away from collecting practices in favor of experiencebased concepts. This development could challenge the traditional view of museums, which have historically been defined in terms of collecting, conservation, research

This thesis examines customer satisfaction within IKEA's support services in Sweden and Great Britain by analyzing customer feedback data. It explores the intersection of anthropology and computational social science, contributing to the growing field of computational anthropology. The study identifies recurring themes in customer comments by employing a mixed-methods approach that combines co

Ända sedan 1800-talet har det stått klart att för den som vill utforma termodynamiska processer finns det oundvikliga kompromisser. Bland de främsta av dessa är att för en värmemotor måste man välja mellan kraft eller effektivitet: en kraftfull motor kan inte vara effektiv, och en väldigt effektiv motor kan inte vara kraftfull. Detta var länge accepterat som en oundviklig konsekvens av termodynamiWe investigate the validity of thermodynamic uncertainty relations (TURs) in a strongly correlated quantum dot system operating in the Kondo regime. TURs place fundamental bounds on the trade-off between precision and dissipation in non-equilibrium systems, and while these bounds are rigorously proven for classical stochastic dynamics, they are not guaranteed to hold in quantum-coherent, strongly

How individuals collect their own digital personal archives have undergone changes since the introduction and development of digital technologies and the internet. At the same time, archival institutions and archival research have become more aware of the importance of the collection and preservation of personal archives as part of our common cultural heritage. Research in the area of appraising d

The purpose of the study is to contribute with new knowledge regarding the present-day preservation of video in Swedish archives, more specifically video as recorded on magnetic tapes. In the study a distinction is made between magnetic tapes and VHS-tapes, as the colloquial use of the brand name VHS is often used to categorize all magnetic tapes. The research questions centre on how the preservat

This Master's thesis explores how municipal archivists in selected municipalities in Skåne, Sweden, perceive and manage archival collections composed of diverse data carriers. Drawing on practice theory and based on qualitative interviews, the study addresses three analytical categories: the view on mixed collections, which highlights perceived challenges; routines, which examine the strategie

The digital transformation impacts the archive sector, the threat picture is rising and creating new demands for information security. This master's thesis investigates how modern municipal archivists manage information security and the challenges they face in this evolving landscape. The study aims to complement existing research by exploring how archivists navigate the growing information se

Artificial intelligence (AI) development thrives on global datasets, yet every outbound transfer of EU personal data must now satisfy two demanding regimes; the General Data Protection Regulation (GDPR) and the Artificial Intelligence Act (AIA). The GDPR lets exporters rely on Adequacy Decisions, standard contractual clauses, or other Article 44-49 tools only if they can guarantee an “essentia

Numerous neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease and amyotrophic lateral sclerosis share a neuropathological hallmark: aberrant protein aggregation in the CNS. Microglia, the brain's innate immune cells, also play a pivotal role in the pathogenesis of these disorders. Multiple studies indicate that these pathological aggregates can propagate throughout the brain
