Fourier transform infrared spectroscopy techniques were used to study the kinetics of gas-phase reactions of three lactones, γ-valerolactone (GVL), 2(5H)-furanone (2(5HF) and 3-methyl-2(5H)-furanone (3M2(5H)F) with Cl atoms, OH radicals and O3 respectively. The experiments were performed in a photochemical reactor at a total pressure of 700 Torr at room temperature (298±2 K). Both relative rate an

Drug-resistant bacterial infections are among the most severe physiological challenges facing human health. Therefore, the detection and inactivation of pathogenic bacteria remains a crucial therapeutic goal in modern society. In this study, we design multifunctional nanocomposites aimed at bacterial binding, fluorescence labeling, and synergistic antibacterial treatment. These nanocomposites are

Depressive and anxiety disorders are leading causes of disability globally. Therapist-guided, Internet-delivered cognitive behaviour therapy (ICBT) is an established treatment for depression and anxiety, but a considerable proportion of treated patients do not achieve sufficient improvement. Predicting symptom changes based solely on clinical variables is challenging, and genetic data could offer

Purpose: Abdominal wall complications can be reduced by adhering to guidelines for midline laparotomy closure. However, implementation of guidelines can be challenging. To address this issue, a laparotomy closure device for swift and standardized abdominal closure was developed. The study evaluated the quality of the suture, safety, and speed of the device in a clinical setting. Methods: A prospec

För att främja ett aktivt och hälsosamt åldrande (AHA) är det avgörande att förstå hur olika generationer använder digitala teknologier, då dessa verktyg blir en alltmer integrerad del av vardagen. Detta avhandlingsprojekt undersökte teknikanvändning bland kvinnor och män i tre åldersgrupper som representerar olika generationer (30–39, 50–59 och 70–79 år), med fokus på attityder, användningsmönsteTo promote active and healthy ageing (AHA), it is essential to understand how different generations engage with digital technologies, as these tools are becoming increasingly integral to everyday life. This thesis project explored technology adoption among men and women from three age groups representing different generations (30–39, 50–59 and 70–79 years), focusing on attitudes, usage patterns, a

The metalorganic chemical vapor deposition (MOCVD) dynamics of beta-gallium oxide (β-Ga2O3) growth using trimethylgallium (TMGa) and oxygen as precursors were investigated through both theoretical thermodynamic analysis and experimental validation in a horizontal low-pressure hot-wall reactor. Thermodynamic analysis revealed that high-purity β-Ga2O3 can be grown through the complete combustion of

Gamified virtual reality (VR) environments are increasingly used to enhance engagement and learning, yet most designs still adopt a one-size-fits-all approach that overlooks motivational diversity. The HEXAD framework, which classifies users into six player types, provides a promising lens for addressing this gap, but its predictive validity in immersive VR remains contested. This study investigat

Major Depressive Disorder (MDD) is a leading global health challenge, affecting nearly 5% of the population. Mounting evidence suggests that systemic low-grade chronic inflammation (SLGCI) plays a central role in the development and progression of MDD. This persistent inflammatory state results from unresolved immune activation and sustained exposure to modern lifestyle factors, such as sedentary

Atmospheric inverse modelling and ecosystem data assimilation are two complementary approaches to estimate CH4 emissions. The inverse approach infers emission estimates from observed atmospheric CH4 mixing ratio, which provide robust large scale constraints on total methane emissions, but with poor spatial and process resolution. On the other hand, in the ecosystem data assimilation approach, the

Introduction: Implementing new treatment regimens entails a learning phase with a concomitant risk of suboptimal results. High caseload has generally been shown to improve results in complex surgical procedures. This study aimed to evaluate results of Cytoreductive Surgery (CRS) and Intraperitoneal Chemotherapy (IP), given as Early Postoperative Intraperitoneal Chemotherapy (EPIC) or Hyperthermic

Understanding regional variation in public transport preferences is essential for designing efficient mobility systems. This study examines the stability of preferences for both traditional public transport and demand-responsive transport across three Swedish regions–Stockholm (urban), Skåne (intermediate), and Värmland (rural)–using discrete choice experiments. The analysis focuses on key service

Atmospheric inversions are widely used to evaluate and improve inventories of methane (CH4) emissions across scales from global to local, combining observations with atmospheric transport models. This study uses the dense network of in situ stations of the Integrated Carbon Observation System (ICOS) to explore how well in situ data can constrain European CH4 emissions. Following the concept of int

Wildfires, insect outbreaks, and storms cause large pulses of tree mortality. Climate change amplifies these forest disturbances, yet their future magnitude and extent remain uncertain. Here, we simulated future forest disturbance regimes at 100-meter resolution across Europe using a deep learning–based simulation framework. Our results show that forest disturbances will continue to increase throu

This study explores a novel approach to utilizing waste biomass for syngas production, with the potential for carbon sequestration. An integrated biomass conversion process combining pyrolysis, CO2 reforming, and MILD combustion is proposed. In the proposed system, the bio-oil obtained from pyrolysis can be used in a reforming step, converting it into syngas with a suitable H2/CO ratio for chemica

The biogeophysical forcing resulting from the change in land-surface properties (such as albedo) is of particular interest as it can increase, decrease, or offset the biogeochemical forcing resulting from the changes in atmospheric greenhouse gas concentrations due to deforestation, forest management, or reforestation/afforestation (i.e., land-use/land-cover change, LULCC). Moreover, the biogeophy

Adaptive reuse, the conversion of buildings for new functions, is gaining prominence for its cost-saving and environmental benefits. However, prior research primarily focuses on preserving the building envelope, often overlooking building services such as ventilation, which affect occupant well-being, costs, and environmental performance. This study explores a novel adaptive reuse approach by reus

Climate neutrality of cities has emerged as a critical goal for sustainable urban development. This is typified by the mission in the European Union (EU) to achieve 100 climate neutral and smart cities by 2030. The idea of carbon or climate neutrality holds diverse interpretations. This paper investigates the dominant socio-technical imaginary for urban climate neutrality within the context of the

Non-technical summary. As glaciers shrink and disappear, the benefits they provide to people may also be fading. This makes it more important than ever to look closely at how melting glaciers affect both the environment and the communities that depend on them. To truly understand what is being lost- or even gained- we need to study glaciers from many angles. This includes looking at the science of
