This thesis examines the economic potential of lithium-ion battery storage systems in multi-family residential buildings in Sweden, focusing on profitability, revenue opportunities, and the factors influencing investment decisions. The increasing share of renewable electricity, combined with the electrification of society, has intensified the need for energy storage solutions capable of balancing
Ett förändrat nederbördsklimat i kombination med ökade trafikbelastningar ställer nya krav på vägkonstruktioners utformning och funktion. Syftet med denna litteraturstudie är att undersöka hur vägkonstruktioner påverkas av kraftig nederbörd och tung belastning, samt att analysera skillnader mellan moderna och äldre konstruktioner avseende lastupptagning och vattenhantering. Vidare behandlas hur daA changing precipitation pattern, characterized by shorter but more intense rainfall events, combined with increasing traffic loads, places new demands on road construction design and performance. The aim of this literature study is to investigate how road structures are affected by heavy rainfall and increased loading, as well as to analyse differences between modern and older road constructions
Bygg- och anläggningsprojekt genererar stora mängder schaktmassor, den årliga mängden som uppstår är cirka 60–200 miljoner ton (Naturvårdsverket, 2024). Schaktmassorna behöver hanteras och omhändertas vilket kan innebära att de återanvänds på den plats de uppstått eller att de transporteras bort för att hanteras på annan plats. Däremot kan massorna vara förorenade vilket ställer till problem, exem
Karst caves are known to buffer external climatic variability and track annual temperature and humidity means, yet little is understood about how this buffering extends beyond cave interiors or whether it influences vegetation patterns at cave entrances. This pilot study investigates microclimate (temperature, relative humidity and derived vapour pressure deficit) and vegetation patterns (Shannon
Laccases are multicopper oxidases capable of oxidizing a broad range of phenolic and non-phenolic compounds, making them attractive biocatalysts for lignin valorization and environmental applications. In this work, two bacterial laccases, LacA from Bacillus amyloliquefaciens and MEK from Psychrobacter sp., were recombinantly produced in Escherichia coli BL21 (DE3), purified, and characterized to s
This study examines the relationship between video games exposure and political attitudes among young adults in Sweden. As video games have become one of the most prominent forms of contemporary popular culture and entertainment media, and Sweden ranks as one of Europe’s most founded gaming industries. It is important to understand whether gaming engagement is associated with political socialisati
Background and objective: We established prognostic nomograms incorporating prostate-specific membrane antigen (PSMA) positron emission tomography (PET) parameters standardised by Prostate Cancer Molecular Imaging Standardized Evaluation (PROMISE; PPP1). Here, we develop an updated PPP2 risk score from a large international multicentre registry study. Methods: We included 6128 prostate cancer pati
Importance: The ability to predict sudden cardiac death (SCD) in children and adolescents with hypertrophic cardiomyopathy (HCM) is currently inadequate. Late gadolinium enhancement (LGE) by cardiovascular magnetic resonance (CMR) imaging is associated with SCD events in adults with HCM. Objective: To examine the prognostic significance of LGE in patients with HCM who are younger than 21 years. De
The PResymptomatic EValuation of Experimental or Novel Treatments for Alzheimer's Disease (PREVENT-AD) is an investigator-driven study that was created in 2011 and enrolled cognitively normal older adults with a family history of sporadic AD. Participants are deeply phenotyped and have now been followed annually for more than 12 years (median follow-up 8.0 years, SD 3.1). Multimodal magnetic reson
Background: The benefit of surgical resection for colorectal cancer (CRC) lung metastases is unclear. The aim was to investigate the incidence, treatment strategy, and 5-year overall survival (OS) in CRC patients with isolated lung metastases. Methods: This registry-based retrospective cohort study included patients treated with curative resection of CRC within the county of Skåne during the perio
Time-lapse resistivity surveys are commonly used to monitor temporal changes in the subsurface. In certain cases, it is known from other information that the resistivity will only decrease or increase with time. The 4-D resistivity smoothness-constrained inversion method reduces artifacts due to noise by including a temporal roughness filter constraint that ensures the temporal changes vary in a s
High resolution observations with ALMA have revealed that concentric rings and gaps are common features in protoplanetary disks. The favored mechanism for creating these substructures are planet-disk interactions, in which growing planets open gaps in the disk, and particles become trapped at the pressure maxima that form at the corresponding gap edges. Since the particle density in these pressure
During migratory endurance flights, which are energetically very demanding, migrants have to deal with prolonged elevated generation of reactive oxygen species (ROS). To limit the damaging actions that ROS have on lipids and proteins, migrating birds are known to upregulate their antioxidant defence system. However, there may be additional ways to limit oxidative damage incurred from flying. Migra
Our overall understanding of long-term climate dynamics is largely based on proxy data generated from archives such as ice cores, ocean sediments, tree rings, speleothems, and corals, whereas reconstructions of long-term changes in vegetation and associated climate during the Holocene are largely based on paleoecological records from peat and lake sequences, primarily pollen and plant macrofossil
Background: Proinflammatory mechanisms are implicated in pain states. Recent research indicates that patients with osteoarthritis (OA) with signs of central sensitization exhibit elevated cerebrospinal fluid (CSF) levels of interferon gamma-induced protein 10 (IP-10), Fms-related tyrosine kinase 1 (Flt-1), and monocyte chemoattractant protein 1 (MCP-1).Methods: The current prospective cohort study
Streptococcus pyogenes is known to cause both mucosal and systemic infections in humans. In this study, we used a combination of quantitative and structural mass spectrometry techniques to determine the composition and structure of the interaction network formed between human plasma proteins and the surfaces of different S. pyogenes serotypes. Quantitative network analysis revealed that S. pyogene
I denna avhandling beskrivs processesen att implementera och optimisera metoder inom kvantitativ magnetresonansomografi (MRT) på en fältstyrka av 7 T. Metoderna är baserade på gradientekon med påtvingad transversell urfasning (spoiling) och applicerade på den mänskliga hjärnan i syfte att avbilda i huvudsak tre olika MR-parametrar: Den longitudinella relaxationstiden (T1), magnetization transfer
