Background. Airborne SARS-CoV-2 plays a prominent role in COVID-19 transmission. Numerous studies have sampled air from patient rooms, but airborne spread to other hospital areas such as corridors is less investigated. Methods. Size-fractionated aerosol particles were collected weekly, with 12 hours of sampling time daily, in corridors at two infectious disease wards in southern Sweden between Mar

The addition of polypropylene (PP) fibres has been shown to reduce the fire spalling propensity of concrete. When including this type of fibres in the concrete, the concrete mix becomes less robust, and small deviations in the constitutes change the workability and properties of the concrete. So, from a manufacturing perspective as small dosages as possible of PP fibres are desirable. Very few lar

Tauopathies belong to a group of neurodegenerative diseases that are characterized by the presence of neurofibrillary tangles in neurons and includes diseases such as Alzheimer´s disease and frontotemporal dementia. Neurofibrillary tangles are insoluble deposits that are composed mainly of tau, which normally acts to stabilize microtubules. In disease, tau forms fibrillar and oligomeric species, w

An inverse class D power amplifier and a class A power amplifier are designed at schematic level for 20 dBm power class and NB-IoT specification in 65 nm CMOS technology. A suitable switch mode supply modulator is also designed. Three different efficiency enhancement techniques namely EER, Hybrid EER and ET are studied and the suitable transmitters are simulated for each in Cadence Virtuoso. These

Over the course of almost four decades the world has been left vulnerable by the HIV epidemic. Displaying the biggest public health challenge currently, many scholars aim to further the understanding of the mechanisms of the spread of HIV. This study aims to contribute to the existing body of literature through adding a spatial aspect to research performed on HIV key drivers in Uganda. Furthermore

The preferred method for synthesising therapeutic peptides today is by Solid-Phase Peptide Synthesis (SPPS). SPPS is a wasteful process, where the main component of the waste is hazardous solvents, i.e., N,N-dimethylformamide (DMF), N-methylpyrrolidone (NMP) or dichloromethane (DCM). 3 It is therefore desirable to search for new and greener solvents to use for SPPS, which is what has been studied

Inadequate water infrastructural development and high costs of water are few of the many challenges that affect water access in Kibera. Consequently, many alternatives to piped water grew out of necessity to meet the needs of residents. The aim of this thesis is to examine the conditions that have led to poor water provision in Kibera and how transitions to improved water access can be achieved by

In Sweden, hypertension, is one of the most common reasons to attend primary care thus a Swedish public health problem of epic proportions. There is a general consensus about that effective antihypertensive treatment reduces the risk of developing cardiovascular diseases and premature death. Non-pharmacological treatment is advocated to be the basis of treatment. The caregiver is responsible for s

A proteoglycan is a protein with at least one glycosidic chain or glycosaminoglycan (GAG) covalently bound to it. Since a common linker between the core protein and the GAG chain has a xylose present, the biosynthesis of GAGs can be primed using xylosides containing hydrophobic aglycons providing that these xylosides are capable of penetrating the cell membrane. 2-naphthyl β-D-xylopyranoside prim

Närståendes närvaro hos patienter som är kritiskt sjuka underlättar enligt studier patienternas vistelse på intensivvårdsavdelningen. För att stödja och tillhandahålla information till de närstående bör personal på intensivvårdsavdelningar vara medvetna om närståendes uppfattningar. I Kanada har ett enkätformulär FS-ICU utvecklats för att undersöka närståendes tillfredsställelse med vården och med

Context. The Milky Way nuclear star cluster (MWNSC) is located in the Galactic centre, together with the Milky Way nuclear stellar disc (MWNSD), and they dominate the gravitational potential within the inner 300 pc. However, the formation and evolution of the two systems and their possible connections are still under debate. Aims. We reanalysed the low-resolution KMOS spectra in the MWNSC with the

Peatlands store a substantial amount of carbon in the terrestrial ecosystem. They are both long-term sinks of organic carbon and a major natural source of atmospheric methane. The accumulation of carbon is a result of net primary production surpassing decomposition rates over millennia, whereas methane production is intricately linked to the anaerobic decomposition of carbon mass. Warming-induced

The increasing use of generative artificial intelligence (GenAI) in advertising has transformed creative production while simultaneously raising concerns about transparency, authenticity and consumer perception. With the growing integration of GenAI into advertising, understanding how consumers respond to AI disclosure has become increasingly important. This study investigates how AI disclosure in
