The colorimetric 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay was standardized for direct detection of rifampin-resistant Mycobacterium tuberculosis in sputum samples. The sensitivity and specificity of the direct MTT assay matched those of the standard indirect susceptibility assay on 7H10 medium, and interpretable results were obtained for 98.5% of the samples within
"Foreword: The durability of building materials, especially the corrosion of reinforcement in concrete structures, has been a main research area in Scandinavia during the last decades. Results from many laboratories in the Scandinavian countries, and outside of Scandinavia, indicate that there are certain relationships between the service life and different concrete parameters, such as the water/b
The ForSAFE-VEG model was used to investigate the impacts of climate change and air pollution scenarios on soil chemistry and ground vegetations composition. In particular, the model involves a ground vegetation model incorporating plant changes to ambient site conditions in terms of climate and chemistry, but the model also incorporate competition between the different plant groups. The model was
Modern doubly fed induction generator (DFIG) wind turbines can ride through a symmetrical fault in the network by using a chopper protection on the direct current (DC) link without triggering a crowbar protection. A novel method to model the DC link system of such wind turbines as an equivalent resistance during symmetrical faults is presented in this paper. The method allows looking at the DFIG w
China's natural wetlands occupy 3.77% of the land and provide 54.9% of China's ecosystem services. Healthy natural wetland ecosystems play an important role in the sustainable development of China, which was realized by the Chinese government in the early 1970s. In the past 5 years, China has made great efforts in wetlands conservation, which is signified by the funding of billions of dollars to r
Background/Aims: Survival for patients on renal replacement therapy (RRT) has been shown to correlate to the level of physical activity and exercise capacity. We examined whether composite measures of functional status at the start of RRT predict survival. Methods: In this retrospective study, the same physiotherapist, using a standardized battery of tests for functional status, tested 134 patient
Introduction For the future conservation, restoration and daily maintenance the need for developing non-destructive and in-situ investigations is vital. At Lund University in Sweden an interdisciplinary research project is being held aiming at, with the help of a mobile system of remote fluorescence lidar, survey and study the facades of historic monuments, and to develop the method and its applic
This thesis aims to examine whether archive pedagogy is a useful learning resource in school today, and if so, how this cooperation works in reality. We want to find out how the archive's educational resources are perceived by teachers and students, and where the possible obstacles may lay. By examining how teachers and students perceive the archive education, our study can contribute to bette
End Stage Renal Disease (ESRD) is a chronic kidney disease which results in lifelong care and regular dialysis treatments. It is both an expensive and extensive diagnosis that causes a lot of suffering for the patients. The workload on the healthcare system is increasing drastically, due to a population that lives longer with more chronic diseases. In this project, input data to an AI system was i
This thesis is an ethnographic study of Chinese visitors’ participation in culinary tourism in the Öresund region. It aims to do qualitative research on the consumption of exotic food and the status of cooking with locals’ activity among Chinese tourists and to deliver insights to culinary tourism agencies in terms of attracting Chinese tourists to joining the food-related activities in present an
This master’s thesis concerns archivists and the work they do. Archivists view themselves as information specialists, but not many people in society have knowledge about this. In this master’s thesis, four deep interviews have been held with archivists working in different environments. Their opinions and experiences help paint a picture of what working life can be like when working in a field tha
Surging outlet glaciers are important in draining large ice caps, but the mechanisms controlling surge periodicities are poorly known. We investigated a sediment sequence from the glacier-fed Lake Logurinn in eastern Iceland, and our unique annually resolved data, based on sedimentary varves, imply that Eyjabakkajokull, an outlet glacier of Vatnajokull, began surging about 2200 cal a BP (before 19
Acute myeloid leukemia (AML) is a heterogeneous disease of the myeloid lineage. About 35% of AML patients carry an oncogenic FLT3 mutant making FLT3 an attractive target for treatment of AML. Major problems in the development of FLT3 inhibitors include lack of specificity, poor response and development of a resistant phenotype upon treatment. Further understanding of FLT3 signaling and discovery o
I denna uppsats ger jag en inblick i hur bibliotekarier på folkbibliotek uppfattar, förstår och interagerar med algoritmer och AI i relation till sitt yrke. Mitt främsta fokus ligger på hur bibliotekariernas uppfattningar av algoritmer och AI i slutändan formar deras handlingar. För att uppnå detta syfte tar jag min utgångspunkt i deras personliga syn på algoritmer och AI. Materialet för denna uppIn this thesis I provide insight into how librarians at public libraries perceive, understand, and interact with algorithms and AI in relation to their profession. My main focus lies in how librarians’ perceptions of algorithms and AI ultimately shape their actions. To achieve this aim I take my starting point from their privately held views of algorithms and AI. The material for the thesis is gat
Corporate Social Responsibility (CSR), ofta översatt till svenska som företagens samhällsansvar, är något som diskuterats flitigt under de senaste åren. Utvecklingen av CSR har dock pågått sedan 1950-talet och fortsätter att utvecklas än idag. Majoriteten av denna utveckling har skett inom den ekonomiska vetenskapen och inom ramen för företagens arbete med CSR. Det är först under de senaste 20 åreCorporate Social Responsibility (CSR) is something that has been discussed heavily in recent years. The development of CSR has been evolving since the 1950s and continues to evolve today. The majority of this development has taken place in economic science and within the framework of the companies work with CSR. It is only in the last 20 years that lawyers have seriously interested themselves in t
The scale at which greenhouse gases are produced by human activities is a global problem, and as such it is being targeted broadly both by political means as well as technologically. One of the major contributors to the emission of green house gases globally, as well as in Sweden, is the transportation sector. This poses an opportunity for technologies that aim to reduce impact of the transport se
This dissertation has examined Fjällrävens backpack Kånken, and its interconnection with the individual's social identity, as well as the group affiliation to the style culture indie. The study has also treated Kånken and its expression of fashion in connection with the style culture indie. In the answering of questions we have conducted an ethnographic study, with a total of 8 people being in
Facing the climate change and the energy crisis, the governments are taking steps to reduce the energy use and enhance the integration of renewable energy installations. Built environment is attributed to 40% of the global energy use, and the literature indicates that integrating the local renewable energy sources to the grid and meanwhile renovating the buildings can significantly improve the ene
Due to society’s modernization and climate changes, transboundary crisis is becoming more severe. This means that communication in many cases needs to be virtual, especially via radio, instead of face-to-face. At the same time, there is a willingness to co-locate in a greater extent. The aim of this paper is to increase the understanding of how the means of communication affects the outcome of a
There is a constant need for the fire and rescue service to develop new methods, materials and extinguishing media to implement the most effective firefighting operations as possible while minimizing environmental impacts. The effect of additives in the extinguishing water is fairly unknown. In this report small-scale experiments shows that additives and fire retardants can provide a significant i
