The cost of ownership of a power plant is partly governed by the efficiency of the turbine island. The turbine stands for the production revenues when transforming the energy in fuel into electric power and district heating. One gauge of the quality of the individual processes is the component efficiency - the current work addresses the turbine part of the power plant. The turbine efficiency is d
Background: Particle exposure is a risk factor for cardiovascular diseases. Mitochondrial DNA (mtDNA) is a primary target for oxidative stress generated by particle exposure. We aimed to elucidate the effects of occupational exposure to particle-containing welding fumes on different biomarkers of mtDNA function, and in turn, explore if they modify the association between particle exposure and card
Neural transplantation holds promise for focal CNS repair. Owing to the shortage of human donor material, which is derived from aborted embryos, and ethical concerns over its use, animal donor tissue is now considered an appropriate alternative. In the USA, individuals suffering from Parkinson's disease, Huntington's disease, focal epilepsy or stroke have already received neural grafts from pig em
Befolkningen växer och andelen som vill bo i städer ökar stadigt vilket skaparbehov av ny mark att bygga bostäder på. Tidigare har de flesta städer och orterutvecklats genom att växa utåt, vilket har lett till förlust av naturområden ochjordbruksmark och ökat beroendet av bilar. Att bygga staden inåt istället, så kallad förtätning, är numera en populär strategi för att minska bostadsbristen. I denThe proportion of people living in densely built up areas is gradually increasing,forcing cities to generate new land to build homes upon. In this process there is a risk for an inexplicit decrease of green space. The green features ofneighbourhoods help to create a supportive environment for health and physicalactivity, thus a reduction of greenness may reduce the general well-being in thepopulat
This paper presents a freely distributed, open-source toolbox to predict the behaviour of urban wastewater systems (UWS). The proposed library is used to develop a system-wide Benchmark Simulation Model (BSM-UWS) for evaluating (local/global) control strategies in urban wastewater systems (UWS). The set of models describe the dynamics of flow rates and major pollutants (COD, TSS, N and P) within t
The development of new materials for solar-to-energy conversion should consider stability, ease of fabrication, and beneficial photophysical properties. In this context, a set of novel π-conjugated building blocks, with phospha- and arsaalkenes possessing a unique dithienyl annulated heterofulvenoid core, have been prepared as air- and moisture-stable sensitizers. These compounds unify electron-do
This paper sets up a framework for designing a massive multiple-input multiple-output (MIMO) testbed by investigating hardware and system-level requirements such as processing complexity, duplexing mode and frame structure. Taking these into account, a generic system and processing partitioning is proposed which allows flexible scaling and processing distribution onto a multitude of physically sep
cholars of electoral authoritarianism and comparative institutions have emphasized how authoritarian regimes implement multiparty elections to stabilize authoritarian rule and diffuse political opposition. Consequently, the literature has advised against the notion that multiparty elections constitute a general lever for democratization. This article presents evidence in support of a more positive
Background. Search and selection of primary studies in Systematic Literature Reviews (SLR) is labour intensive, and hard to replicate and update. Aims. We explore a machine learning approach to support semi-automated search and selection in SLRs to address these weaknesses. Method. We 1) train a classi er on an initial set of papers, 2) extend this set of papers by automated search and snowballing
This review examines the current status of knowledge of sepsis and pneumonia in the elderly population and how the dynamics of the pulmonary challenge affects outcome and consequences. Led by an unprecedented shift in demographics, where a larger proportion of the population will reach an older age, clinical and experimental research shows that aging is associated with certain pulmonary changes, b
