TnBgl1A from the thermophile Thermotoga neapolitana is a dimeric beta-glucosidase that belongs to glycoside hydrolase family 1 (GH1), with hydrolytic activity through the retaining mechanism, and a broad substrate specificity acting on beta-1,4-, beta-1,3- and beta-1,6-linkages over a range of glyco-oligosaccharides. Three variants of the enzyme (TnBgl1A_E349G, TnBgl1A_E349A and TnBgl1A_E349S), mu
Popular Abstract in English N/AAquatic systems worldwide receive large amounts of organic carbon from terrestrial sources. This ‘allochthonous’ organic carbon (AlloOC) affects critical physical and chemical properties of freshwater ecosystems, with consequences for food web structures and exchange of greenhouse gases with the atmosphere. In the boreal region, loadings of AlloOC are particularly high due to leaching from huge or
Popular Abstract in Swedish Materien strävar efter största möjliga oordning (entropi). Det krävs ett aktivt ingripande (energitillskott) för att ordna och separera saker. Har man väl hällt salt i teet är det svårt att ta bort, och byta ut det mot socker. Vid framställningen av olika ämnen får man ofta ut en blandning som även innehåller sådant man inte vill ha, och måste hitta sätt att skilja dem The purification of proteins from raw materials like fermentation broth and other biological sources usually involves several purification steps and is rather time consuming and expensive. This is a major concern in the production of many important protein products e.g. pharmaceuticals such as insulin and blood coagulation factors. One way to speed up the isolation of protein from particle-contai
Background. Traditional crash-based analysis of road safety at individual sites has its shortcomings due to low numbers and the random nature of crashes at individual sites and the related statistical issues, as well as the under-reporting of crashes and lack of information on contributing factors and the process preceding crashes.

Pursuit of the Bioeconomy (BE) and the Circular Economy (CE) is high on the political agendas of many countries. Application of the concepts is intended to ameliorate a number of sustainability challenges, such as raw material constraint concerns and global warming. The concepts of BE and CE are increasingly combined to describe a ‘circular bioeconomy’ (CBE), which emphasises value retention for r
This article discusses social positions of Swedish female converts to Islam who have previously passed as white majority Swedes, but whose experiences have changed, sometimes radically, since donning the hijab. It addresses their accounts of being treated and evaluated differently by teachers, co-workers, family and friends, and having their choices questioned by strangers.

Popular Abstract in Swedish Kunskapsarbete framställs ofta som något som präglas av dolskhet eller oklarhet: produkten som säljs är oklar, resultatet är oklart och även själva arbetsprocesserna framställs ofta som oklara. Detta påverkar i sin tur den styrning som man kan förvänta sig i kunskapsintensiv verksamhet: en styrning som ofta handlar om personalen mer än om arbetet. I denna studie problemKnowledge work is often portrayed as hidden or ambiguous: an ambiguous product is sold, ambiguous results are delivered, and work processes are ambiguous. This in turn affects the type of management expected in knowledge-intensive organisations, where emphasis is on managing people rather than work. In this study, the organisation of knowledge work is discussed and problematized through analysis o
Hepatitis B virus (HBV) infection remains a major public health threat in the Middle East and North Africa (MENA). Phylogenetic analysis of HBV can be helpful to study the putative transmission links and patterns of inter-country spread of the virus. The objectives of the current study were to analyze the HBV genotype/sub-genotype (SGT) distribution, reverse transcriptase (RT), and surface (S) gen
Context. The unprecedented astrometric precision of the Gaia mission relies on accurate estimates of the locations of sources in the Gaia data stream. This is ultimately performed by point spread function (PSF) fitting, which in turn requires an accurate reconstruction of the PSF, including calibrations of all the major dependences. These include a strong colour dependence due to Gaia's broad G ba
Since 1750, land-use change and fossil fuel combustion has led to a 46% increase in the atmospheric carbon dioxide (CO2) concentrations, causing global warming with substantial societal consequences. The Paris Agreement aims to limit global temperature increases to well below 2C above preindustrial levels. Increasing levels of CO2 and other greenhouse gases (GHGs), such as methane (CH4) and nitrou
Aim: Geo-referenced species occurrence records are a prime example of biodiversity data and a cornerstone of biodiversity research. Yet, their availability depends on non-biological factors, including the political framework in the region of collection. Here we present Bio-Dem (www.bio-dem.surge.sh), an open-source software to explore the relationship between the availability of species occurrence
The reliable operation of nuclear reactors is contingent upon precise control mechanisms for critical components, such as the head circulation pumps. This master thesis investigates an innovative approach to address the ramp-down speed of these pumps during external electrical grid failures by exploring the application of a supercapacitor group. Presently, the existing solution relies on a fly-whe
The study shows how a professional service firm can manage intrinsic motivation by using training as a personnel control and how training can help when implementing cultural controls cultural. The results show that professionals’ perceive that all the needs for intrinsic motivation are positively related to training, with autonomy having the strongest relation, while extrinsic motivation to a larg
This report describes the development of a manufacturing process for creating custom-made prosthetic arm sockets using 3D scanning and 3D printing. The process is intended to function as a guide for a prosthetist without requiring an extensive experience in CAD. The project aims to offer a viable alternative to the often time consuming and manual labour-intensive conventional manufacturing method,
Blue straggler stars (BSSs) are exotic stellar objects that appear to be younger than the age of the population they come from suggests. They are observed as the extension of the main sequence stars, beyond the turn-off point. They are present in all types of stellar populations, such as open clusters, globular clusters, dwarf galaxies, and even in the open field. It is believed that they form mai
Unlike most bacteria, Streptomyces grows by extending branching hyphae, forming a mycelium that resembles fungal growth more than typical prokaryotic behaviour. This growth strategy leads to questions about how bacteria control cell shape, polarity, and development in a multicellular context. While many regulatory systems involved in Streptomyces development have been described, others remain poor
