The focus of the thesis is on selection and adaptation processes in bacteria with emphasis on denitrifying bacteria in groundwater. Other nitrogen transformation processes such as dissimilatory nitrate reduction to ammonium (nitrate ammonification) and nitrification of forest soil bacteria are briefly discussed. Intensive fertilisation of agricultural soils in southern Sweden have been performed
A hot potato: food and meals in families with small children and teenagers. Introduction, with aims and hypothesis The project ‘Konsumenters problemlösningar på livsmedelsmarknadens nya arenor. Matinspiration under tidspress’ [‘Consumers’ problem-solving/solution to the food market’s new arenas: food inspiration against the clock’] initially addressed the following issue: shopping for food and p
Popular Abstract in Swedish Polymerer är samlingsnamnet på långa molekylkedjor. Runt omkring oss i vårt dagliga liv är vi omgärdade av polymerer så som plaster, lim, fibrer och proteiner. Utvecklingen av många högteknologiska produkter är starkt beroende av polymera material. Grundläggande kunskaper om dem och deras egenskaper är därför viktigt. I ett batteri kan många fördelar erhållas då den koThere is a growing need for multifunctional polymeric materials for the development of several important energy conversion technologies. For example, the polymer electrolyte is a key component in lithium polymer batteries. The basic functions of this electrolyte are to efficiently conduct the lithium ions and physically separate the electrodes. Consequently, these electrolytes should ideally posse
This book is written by and for researchers who are still in that part of their careers where they are actively using the eye-tracker as a tool; those who have to deal with the technology, the signals, the filters, the algorithms, the experimental design, the programming of stimulus presentation, instructions to participants, working the varying tools for data analysis, and of course, worrying abo
Residual stress can be introduced unintentionally into the workpiece with various magnitudes and distributions through all manufacturing processes. These stresses have a significant effect upon the performance of the final component. Understanding the residual stress imparted by machining is an essential aspect of understanding the machining process and overall part quality. Although many investig
Wetlands are integral components of our natural environment since they provide many critical ecosystem services to humanity, such as water purification, climate change mitigation, flood control, and biodiversity. Although wetlands can convey resilience to some degree of changes, they might be vulnerable to climate change. Altered hydrology and rising temperatures can turn the wetland services into
AbstractSevere perineal trauma (SPT) is a serious complication following vaginal birth. To reduce its incidence rate, various preventive strategies have been implemented in Swedish obstetric units. Collegial midwifery assistance (CMA), involving an additional midwife being present during the active second stage of labour, is a clinical practice that was evaluated in the Oneplus trial, which proved
“Those who can make you believe absurdities can make you commit atrocities” is a famous aphorism commonly attributed to Voltaire. The choice to publish under an alias for François-Marie Arouet, reveals that there was some sort of awareness of the relationship between power, knowledge, truth and people’s tyrannical tendencies on his part. What our dear enlightened friend could most likely not fores
Popular Abstract in Swedish Sotpartiklar i atmosfären är en del av klimatfrågan som är i särskilt stort behov av utredning. Dessutom har det visat sig, att samma partiklar orsakar mycket stora hälsoproblem; globalt, på Europeisk nivå, och till och med i förhållandevis förskonade länder som Sverige. Vi vet nu nästintill helt säkert att mänsklig påverkan leder oss in i ett varmare klimat. Vi behöveAerosol particles contribute significantly to the global burden of disease, and remain the main source of uncertainty in assessments of human-induced climate change. The microphysical characterization of particles is necessary to understand the roles they play in the detrimental effects of air pollution on human health, and in the energy budget of our planet. Soot particles are especially relevant
The traditional sheet metal forming process, including cast steel die tool and conventional work materials, is fairly well established and analysed. Developments of new alternative materials make great demands upon new forming processes and manufacturing methods. A general goal for the manufacturing industries is to reduce the weight of metal parts, reduce batch sizes and reduce the lead-time of n
This report is the result of a joint research project between Lund University and Copenhagen Business School, mainly financed by the Öresund University. The main research question was: Can the Öresund region position itself as a leading logistics centre in Scandinavia, in the light of the new conditions that the bridge brings? The purpose was to create a fundamental understanding of the new logist
En slitsmur är en geokonstruktion som utförs genom att paneler platsgjuts med marken som form. Panelerna bildar tillsammans en samverkande vägg. Tekniken är vanlig utomlands men fortfarande relativt ovanlig i Sverige. Behovet, och därmed intresset, av slitsmurar i Sverige växer dock i takt med förtätningen av städer och infrastrukturprojekt som kräver djup schaktning och anläggning. Kraven på låg A diaphragm wall is a retaining wall which is produced as a cast in-situ concrete wall. The ground itself acts as formwork. The technique is widely used internationally but it is comparably still a rare technique in Sweden. However, the need, and therefore interest in Sweden for diaphragm walls is growing as the number of inner city infrastructure projects requiring deep excavations increases. The
Inom EU pågår ett arbete för att framta ett regelverk beträffande ansvar för AI med syfte att bland annat främja utbyggnaden av AI och säkerställa effektiva ersättningsmöjligheter för skadelidande. Som ett led i detta rekommenderade Europaparlamentet den 20 oktober 2020 ett krav på obligatorisk ansvarsförsäkring för högrisk-AI. Trots detta saknas förslag om försäkringsplikt i det efterföljande dirThe EU is currently drafting a legal framework regarding liability for AI with the purpose of promoting the rollout of trustworthy AI, while ensuring effective compensation for potential victims. As a part of this, the European Parliament on 20 October 2020 recommended compulsory liability insurance for high-risk AI. Despite this, the succeeding proposal for a directive on AI-liability lacks such
Cement är ett av världens mest använda material och agerar som bindemedel i betong och murbruk. Portlandcement, som är den mest förekommande typen av cement, produceras årligen i en kvantitet av fyra miljarder ton. Cementproduktionen står för ca 7 % av de globala koldioxidutsläppen och det finns ett stort intresse i att hitta alternativa vägar och optimeringsmöjligheter, för att minimera klimatpåvCement is one of the world's most used materials and acts as a binder in concrete and mortar. Portland cement, which is the most common type of cement, is produced annually in a quantity of four billion metric tons. Cement production accounts for approximately 7 % of the global carbon dioxide emissions and there is a great interest in finding alternative routes and optimization possibilities,
Den snabba tekniska utvecklingen rörande artificiell intelligens öppnar upp för många juridiska frågor, inte minst vad rör upphovsrätt. I syfte att kunna gene-rera material med hjälp av artificiell intelligens krävs det att tillhandahållare av AI har tillgång till stora mängder data, för att kunna träna upp dessa till att producera resultat som efterliknar mänskliga verk. Frågan som därigenom uppsThe rapid technological development of artificial intelligence gives rise to nu-merous legal issues, particularly concerning intellectual property. For artificial intelligence to generate material, it must be trained on human-created works to produce results that resemble such. This process requires access to large vol-umes of data, often sourced from the internet and large databases. The ques-tio
