Behandling av avloppsvatten för att avlägsna ämnen som kan ha en negativ påverkan på den mänskliga hälsan och naturen är mycket viktigt innan vattnet återanvänds eller släpps ut i naturen. Intresset för anaerob vattenrening har ökat eftersom det är ett bra komplement till aeroba processer, samt för att det producerar energi i form av metangas. Målet med detta projekt var att undersöka hur olika dTreatment of wastewater is crucial for removing any compounds which can have a negative impact on human health and nature before the water is reused or released into nature. Interest in anaerobic treatment of wastewater has increased as it is a good complement to aerobic treatment, and it produces energy in form of methane. The aim of this project was to investigate how different operational para

Augmented Reality (AR) är på uppgång och många företag lägger miljontals dollar i branschen. Både Google och Apple har nyligen släppt sina egna AR SDK’er som kommer att köras på miljontals enheter inom en snar framtid. AR är verkligen fascinerande och har sagts vara nästa miljard-industri. Målet med denna avhandling är att undersöka vad som är möjligt med dagens AR för mobila enheter och undersökaAugmented Reality (AR) is on the rise and a lot of companies put millions of dollars into the industry. Both Google and Apple have recently released their own AR SDKs that will run on millions of devices in the near future. AR is really fascinating and have been said to be the next multi-billion-dollar industry. The goal of this thesis is to explore what is possible with today’s AR and what are th

Innovation är ett vidkänt koncept som har fått ökad betydelse i dagens organisationer. Uppmärksamhet har framförallt riktats till de initiala faserna av innovationsprocessen, kallade Fuzzy Front End (FFE). Att hantera FFE effektivt har blivit nödvändigt i utvecklingen av nya innovativa produkter, eftersom det kan minska cykeltider och kostnader relaterat till produktutvecklingen. Det är dock svårtInnovation is a widely known concept which has received increased importance in today's organizations. Attention has especially been directed to the initial phases of the innovation process, commonly referred to as the Fuzzy Front End (FFE). Managing the FFE effectively, has become essential in the development of innovative products, since it can reduce cycle times and costs related to product

Achieving the 17 Sustainable Development Goals (SDGs) depends on timely and reliable information. However, standardized methodologies and regularly available data exist for only 40% of the 232 indicators. The “Data Revolution for Sustainable Development” is supposed to bridge these data gaps by harnessing ongoing developments in information technology, particularly big data. Currently existing pil

This thesis explores the functionality of Extend Producer Responsibility (EPR) in the management of Electrical and Electronic waste (e-waste) in Kenya using a case study on manufacturer involvement in end-of-life management. To achieve the purpose of the study the analytical framework used incorporates Environmental effectiveness, Economic efficiency, Political acceptability, Administrabilty and I

Humanity is facing one of the greatest challenges ever. Climate change and global warming is a great risk and our consumption and dependency of fossil fuel are important causes of this accelerating issue. My thesis aims to design an entry for the professional debate about what urban areas in a fossil free future might be like. I’m investigating how an urban environment that requires as little tra

When it comes to innovation, economic growth, affluence and international attractiveness, there are currently few places in the world that can compare with the San Francisco Bay Area. However, new megatrends such as Sustainability, can challenge its attractiveness. Scholars talk about the “Nordic approach”.In the geographical area of Southern Scandinavia, ‘The Strait Area’, the focus is on Sustai

Recently, the incentive structure facing doctoral students and researchers in economics has changed significantly in many European countries as a result of the adoption of the US approach to evaluating research output. This poses a threat to the development and position of the subject of economics in Europe since evaluation for promotion is characterised by an excessive focus on publishing in the

The search for drugs that modulate NMDA receptors has been very active in the latest decades since they play a pivotal role in neuronal death and in several neurological conditions, including stroke, traumatic brain injury, and neurodegenerative diseases. Activating the receptor evokes an entry of calcium into the neuron, thus leading to a rapid depolarization that can be measured using electrophy

To avoid over-treatment of prostate cancer patients following screening for elevated prostate-specific antigen (PSA) levels, keeping patients on active surveillance has been suggested as an alternative to radical treatment. This means reoccurring visits for patients with low-grade cancer to monitor progression. The Prostate Cancer Research International Active Surveillance (PRIAS) study was initia

The interactions between aerosols and clouds are still one of the largest sources of uncertainty in quantifying anthropogenic radiative forcing. To reduce this uncertainty, we must first determine the baseline natural aerosol loading for different environments. In the pristine and hardly accessible polar regions, the exact nature of local aerosol sources remains poorly understood. It is unclear ho

Background: The aim was to develop a theoretical framework for how errors in estimated activities propagate to a dispersion in time-integrated activity in radionuclide-therapy dosimetry and how this affects the comparison of radionuclide-therapy dosimetry schemes. Methods: Formulae for the variance of relative errors of estimated time-integrated activities and relative differences in time-integrat

In clinical trials, surrogate endpoints, that are more cost-effective, occur earlier, or are more frequently measured, are sometimes used to replace costly, late, or rare true endpoints. Regulatory authorities typically require thorough evaluation and validation to accept these surrogate endpoints as reliable substitutes. To this end, the meta-analytic framework is considered a very viable approac

Aphids cause massive agricultural losses through direct damage or as pathogen vectors. Control often relies on insecticides, which are expensive and not selective. An interesting alternative is to use aphid sex pheromones nepetalactone (NON) and nepetalactol (NOL) to interfere with aphid mating or attract aphid predators. Here, we explore production of these compounds in plants, as their precursor

Developing an efficient code for large, multiscale astrophysical simulations is crucial in preparing for the upcoming era of exascale computing. RAMSES is an astrophysical simulation code that employs parallel processing based on the message-passing interface (MPI). However, it has limitations in computational and memory efficiency when using a large number of CPU cores. The problem stems from ine

Designing technologies that clothe, adorn, or are otherwise placed on the body raises questions concerning the role they will play in dressing ourselves. We situate self-fashioning - or the process through which we stylise and present our bodies - as a complex practice where a series of social, material, and contextual factors shape how we present ourselves. Informed by reflective discussions and

Background The fundamental problem with the pavement marking letter design is dealing with the phenomenon of image distortion by perspective. Because there has been a lack of a systematic way to deal with the problem on Korean pavement marking letters, the outputs have been determined by the installer's subjective design judgement. Ultimately, this causes low legibility. The purpose of this study
