Carbon-based materials are highly sought after due to their superior properties, making them valuable for high-performance applications. However, most carbon-based materials are derived from fossil sources, and their synthesis often involves hazardous chemicals. Therefore, it is essential to develop sustainable methods for synthesising these materials from renewable resources, using fewer solvents
Wind energy is an increasingly viable solution for sustainable power generation, particularly in developing regions with high wind potential. This paper presents a comprehensive analysis of the wind power and energy output estimation for the Sela Dingay wind farm, a candidate site in Ethiopia. The study utilizes measured wind speed data at 50 meters and interpolates it to different hub heights (91
Highly insulated external wall assemblies are commonly employed to enhance building energy performance. However, research indicates that these assemblies may lead to moisture-related issues, such as mould growth. Recent studies suggest that the use of highly hygroscopic insulation materials, owing to their higher moisture buffering value, may mitigate relative humidity levels and consequently the
Att ställa om från fossila bränslen inom sjöfartssektorn kommer att bli ännu svårare än att vända en oljetanker. Det övergripande syftet med denna avhandling, som är förankrad i sustainability transitions-litteraturen, är att öka den nuvarande förståelsen för hur multiskalära uppifrån-och-ner- samt nerifrån-och-upp-processer påverkar sociotekniska förändringar som bidrar till minskade koldioxidutsShifting away from fossil fuels in the maritime shipping sector promises to be even more difficult than turning an oil tanker. Anchored in the sustainability transitions literature, the overall aim of this thesis is to advance the current understanding of how multi-scalar top-down and bottom-up processes influence socio-technical change towards decarbonisation of the global maritime shipping secto
OBJECTIVES: To examine physical activity level prior to pregnancy, during pregnancy and postpartum and investigate the association with depressive symptoms postpartum among women in Sweden.STUDY DESIGN: Retrospective observational study including 532 women on self-assessment of physical activity level before pregnancy, during pregnancy and postpartum, depressive symptoms postpartum as well as stre
The high energy consumption of electronic data processors, together with physical challenges limiting their further improvement, has triggered intensive interest in alternative computation paradigms. Here we focus on network-based biocomputation (NBC), a massively parallel approach where computational problems are encoded in planar networks implemented with nanoscale channels. These networks are e
We studied ice-nucleating abilities of particulate emissions from a modern heavy-duty diesel engine using three different types of fuel. The polydisperse particle emissions were sampled during engine operation and introduced to a continuous-flow diffusion chamber (CFDC) instrument at a constant relative humidity RHwater=110 %, while the temperature was ramped between −43 and −32 ∘C (T scan). The t
Throughout history, people have used products from different microorganisms and plants for many medicinal and nutritional applications. Chilli peppers have been used for spicing up food, but also for their pharmacological properties. They contain alkaloid molecules called capsaicinoids, which have been shown to activate and desensitise the heat receptor - Transient Receptor Potential Vanilloid typ
In this paper we study structure from motion problems for parallel cylinders. Using sparse keypoint correspondences is an efficient (and standard) way to solve the structure from motion problem. However, point features are sometimes unavailable and they can be unstable over time and viewing conditions. Instead, we propose a framework based on silhouettes of quadric surfaces, with special emphasis
Background: Patient safety gained public notoriety following the 1999 report of the Institute of Medicine: To Err is Human – Building a Safer Health System which summarized a culminated decades' worth of research that had so far been largely ignored. The aim of this study was to analyze the report's impact on patient safety research in anesthesiology.Methods: A bibliometric analysis was performed
IntroductionInternet-based interventions are called for within rehabilitation to meet the limited access to support for self-management after stroke. Therefore, a new intervention program, “Strategies for Empowering activities in Everyday life” (SEE) was developed. The aim of this study was to explore and describe how clients with stroke and their occupational therapists experienced the SEE interv
This article analyzes the utilization of the concept “Gnosticism” in a form of Satanism that has come to be known as “Chaos Gnosticism,” or “Gnostic Satanism.” The topic of the study is the Swedish expression of this phenomenon attached to Current 218 and the Temple of Black Light, previously named the Misanthropic Luciferian Order (MLO). The group is known as one of the more radical and violent f
The paper reports on the bias stabilization of a 60-GHz resonant-tunneling diode (RTD)-based oscillator operated in pulsed mode. The oscillator contains an on-chip stabilizing capacitor, enabling the minimum dc consumption possible for such an RTD oscillator to be obtained, since all of the dc current is consumed by the active device. This is achieved without imposing restraints on the output powe
High expression of the receptor tyrosine kinase Axl is associated with poor prognosis in patients with Renal Cell Carcinoma (RCC), the most common malignancy of the kidney. The miR-34a has been shown to directly regulate Axl in cancer cells. The miR-34a is a mediator of p53-dependent tumor suppression, and low expression of miR-34a has been associated with worse prognosis in several cancers. Our a
