The ratio of production cross sections of the W and Z bosons with exactly one associated jet is presented as a function of jet transverse momentum threshold. The measurement has been designed to maximise cancellation of experimental and theoretical uncertainties, and is reported both within a particle-level kinematic range corresponding to the detector acceptance and as a total cross-section ratio
Background: Pediatric intestinal biopsy procedures including considerable transpharyngeal manipulation of a wire-guided metal capsule require adequate sedation or anesthesia. This retrospective cohort study was designed to evaluate intravenous sedation with ketamine and low-dose midazolam in young children undergoing these procedures before and also after discharge from the hospital. Methods: A t
AIM: The aim of this study was to investigate early changes in uptake of 2-deoxy-2-[(18)F]fluoro-D-glucose (FDG) in vivo and in vitro in a squamous-cell carcinoma (SCC) cell line originating from a human head and neck SCC during cytotoxic therapy with respect to metabolism in tumor cells and in surrounding stromal tissue. MATERIALS AND METHODS: In 60 nude mice with xenografted SCC, 50 animals were
A multidisciplinary study of the implementation potential of a biorefinery, using forestry residues as feedstock, is performed by assessing techno-economic factors, system integration and feedstock supply. The process is based on biochemical conversion of logging residues to produce ethanol, biogas, pellets, heat and electricity. Nine models were designed in Aspen Plus based on the available feeds
This paper reports on two-dimensional (2D) and three-dimensional (3D) direct numerical simulations (DNSs) of the auto-ignition process of a lean H-2/air mixture with temperature stratification in a constant volume enclosure. Detailed chemistry and transport properties are taken into account in the simulations. The combined propagation of spontaneous ignition front and deflagration front is identif
Hemoglobin is the major oxygen-carrying system of the blood, but has many potentially dangerous side effects due to oxidation and reduction reactions of the heme-bound iron and oxygen. Extracellular hemoglobin, resulting from hemolysis or exogenous infusion, is shown to be an important pathogenic factor in a growing number of diseases. This review briefly outlines the oxidative/reductive toxic rea
Today, breast cancer is the leading cause of cancer related death in women. Early detection of breast cancer relapse presents increased treatment options and better control. Protein biomarkers from plasma are currently measured by state-of-the-art methods like ELISA, which require antibodies with high sensitivity and specificity. Developing such assays is laborious and time consuming. Thus, there
China, with the fast developing financial market, experienced two dramatic stock market crisis in recent ten years under government constrains. Thus, monitoring the systemic risk in China is crucial and meaningful. This paper applies CoVaR methodology to measure the dynamic systemic risk of China’s financial market from 1996 to 2016. The financial market is divided into bank and non-bank sectors.
Rapid urbanization has dramatically increased housing demand in Hanoi, the capital city of Vietnam. To alleviate housing shortage, the city of Hanoi has developed a housing program of which the major part is housing development through new urban area projects. New urban area, or new town, projects are large-scale developments designed mainly for residential purposes, with integrated infrastructure
Bangladesh is one of the most densely populated areas in the world, and Rapid urbanization has been a notable trend, with the urban population increasing from 5% to 42% between 1972 and 2023. This internal migration has led to a surge in demand for housing in cities like Dhaka, Chittagong, Sylhet, and Khulna. It is found from the Bangladesh Bureau of Statistics (BBS) that each year, 200,000 units
As the world is trying to rid itself of its dependence on fossil fuels, the need for renewable energy is rapidly increasing. In the power distribution network (DN), this takes the form of distributed generation (DG) from renewable sources, such as photovoltaic (PV) power production. But as more DG is installed, it can lead to issues in the DN such as overloading and overvoltage when production is
Då smarttelefoner på kort tid har blivit oumbärliga verktyg i många människors vardag har frågor kring hur användare psykiskt påverkas av dem väckts. Studier har funnit samband mellan smarttelefonanvändning och psykisk ohälsa, men i många fall baserat på bristfälliga data. Den här studien syftade att vidare undersöka sambandet mellan smarttelefonanvändning och upplevd psykisk ohälsa samt att underSmartphones have rapidly become indispensable tools in everyday life, leading to questions about their psychological impact on users. Studies have found associations between smartphone use and mental health problems, but in many cases based on insufficient data. This study’s purpose was to further explore the relationship between smartphone use and experienced mental health problems, and to determ
Children’s participation could seem to be an obvious ingredient in social services child protection investigations. Children’s rights to make their voice and opinion heard and to affect the decisions that involve them is stated in law, conventions and other regulations. Despite this, a lot of previous studies show that children’s rights often are forgotten or non-prioritized in social services. Th
In recent decades, digitalisation has been a catalyst for economic growth, along which a vital need emerged for contemporary organisations to rapidly anticipate and react to changes. Organisational change is thus a recognised and widely researched topic within the literature. As we study a software implementation, executed as planned change project, we take on a process perspective on change, part
Ecotourism is a rapidly growing niche within the global tourism industry and has deserved the attention of wide circles from academia and the tourism industry internationally. There is, however, void of information on ecotourism in Armenia from theoretical and practical points of view. In light of its ambiguous perception, use and planning for development, the aim of this thesis has been to presen
Jezebel (in this essay, Isebel) is often described as the evillest woman in the Bible and has for many reasons become a favourite in feminist exegesis. In this thesis, I put Jezebel in her context: historical, religious, social, political, and try to discern the following aspects: • How is Isebel as a character depicted in the Bible? • Why is she depicted in this way? • What can we know about Iseb
In the following years we will experience a transition towards Internet Protocol version 6 (IPv6). The reason is the depletion of IPv4 address space due to the rapid increasing numbers of Internet of Things (IoT) devices connection. This transition however poses a problem, since the majority of these devices mostly are mobile and not connected to power source. Neighbor Discovery Protocol (NDP) def
Sweden has the reputation of being one of the most sustainable and innovative countries in the world, when it comes to environment-related technology. However, the ecological footprint rates indicate, that Swedes are currently living lifestyles that would require the equivalent of four Earth-like planets to sustain. Most carbon foot-print emissions are closely connected to household activities, wi
