It is impossible to conceive our modern world without plastics. Since the mass production of plastics began, humanity has produced around 8 billion tons of plastic waste, and only 9% has been recycled. Terephthalic acid polymers such as poly(ethylene terephthalate) (PET) have been massively produced over the last years thanks to their characteristics and applications. Due to their limited biodegra

China’s rapid economic development has led to a continuously increasing energy demand and the country is the world’s biggest energy user as of today. The country accounts for around 23% of the global energy production, but 70% of the Chinese energy is generated with coal power and China is the biggest emitter of CO2 in the world. The Chinese government has set a couple of goals to reduce the count

The genus Caldicellulosiruptor and especially Caldicellulosiruptor saccharolyticus are gaining attention because of their potential as biohydrogen producers from agricultural and forestry waste on an industrial scale. Genetic and in turn metabolic engineering can be used to aid in the characterization of C. saccharolyticus. Additionally, it can be used in strain improvement to overcome limiting fa

Water chemistry alterations such as acidification and eutrophication represent major threats to the running waters of the world, and Swedish waters are among the most vulnerable. In this study the small forested catchment Storskogen, part of the SWETHRO monitoring network, was analysed to examine the links between deposition, catchment hydrological properties and surface water chemistry. Storskoge

MicroRNAs are small single stranded RNA molecules containing approximately 22 nucleotides and these play an important regulatory role in gene expression. MicroRNAs are found to be involved in several diseases and knowledge about their sequences can be an important tool in the foundation of novel treatment methods against diseases. Today, these small RNA molecules are mainly analyzed with qPCR and

The undrained shear strength is a key parameter in the design process of geotechnical structures. One of the most frequently used methods to investigate this parameter is the cone penetration test (CPT). The CPT does not measure the undrained shear strength directly, but instead the resistance that a conic probe encounters as it is pushed into the ground. A calibration factor, the cone factor (Nkt

The steel industry is a large emitter of carbon dioxide and uses a lot of energy. Because of an increased awareness of the detrimental effects of climate change, research in alternative ways to operate steel plants have been made. It is now possible to build plants with far less emissions by using electrolysis and hydrogen reduction. Electrolysis is a technology with a long historical background t

Att jag intresserar mig för stranden som plats för mitt examensarbete är kanske inte så konstigt. Som vågsurfare har jag tillbringat mycket tid på stranden och ute bland vågorna. Genom surfingen har jag upplevt många olika kuststräckor och vågor på jorden, men just stranden och surfingen i Sverige har fångat mitt intresse. Här är årstidernas förändringar och havets stormar de största utmaningarna,It is not that surprising that I chose the beach as the subject of my thesis. As a surfer, I have spent a lot of time on the beach and among the waves. Through surfing I have experienced a wide variety of coastlines around the world, but the beaches of Sweden have peaked my interest. The changing of the seasons and the ocean´s storms are the biggest challenges here for a surfer, not the size of th

It’s been 34 years ago now since the iron curtain has parted the European continent and its inhabitants in an East and a West. The analysed area for the following thesis on the border between northern Austria and southern Czechia gives a case example of a region, that is still suffering from an era, where one sky-direction has been erased from people’s everyday living and thinking – leaving the bo

With the climate change and urbanization process, the frequency of the urban flooding’s occurrence has increased in the recent years. It brings great economic losses to the cities, especially to the basements of individual properties. Low Impact Development (LID), which currently advocated by more city planners for managing stormwater, is considered as a more sustainable way to mitigate urban floo

Friedriech's ataxia is a serious neurological condition that is caused by a deficiency in the expression of the protein frataxin. This deficiency is caused by an extension of GAA repeats in the first intron of the frataxin-coding gene. The disease can have an onset as early as five years and by the time the patient has reached 20 years they often require a wheelchair and help to be able to hav

A part of the project of transforming the worn down medieval fortress Glimmingehus into a tourist attraction for the people of the 20th century, was to dig out the once filled in moat surrounding it. This very labour intensive project did not only result in a nostalgic atmosphere but also a large amount of fairly well preserved finds, since the moat had once been used as a rubbish dump. A part of

A large share of the existing building stock in Sweden originates from the so-called Million Building Programme, a large-scale construction wave between 1965 and 1974 to tackle the housing shortage at this time. Those buildings have very high energy demand and require renovation due to age and often neglected maintenance. The Swedish government’s long-term climate and energy goals are tied to an e

The coastal city of Kalmar is known as an attractive summer destination, both locally and internationally. The coast has long been included as one of the municipality’s priority goals. In its city development vision, the municipality strives to utilize the coast and take it into consideration in urban planning. On the other hand, Kalmar has a historic character, which is visible through its urban

Global warming and climate change is getting a serious issue and a great environmental threat that affects many aspects of life and our ways of living on this planet. The negative effects of climate change are endangering our communities, health and economy. Global warming can be considered as a main reason for sea rising levels, extreme heat which is responsible for many forests’ fires, severe dr

The complexity of climate change creates a need for multifunctional solutions. Urban farming is a tool with potential for adapting and transitioning society. While not a new phenomenon, the incentives have changed and therefore contemporary characteristics for urban farming need to be further examined. This study analyzes how urban farms are valued and central barriers together with drivers. Opera

This thesis analyses ten indepth interviews on domestic workers, class and gender roles with ten young, politically inclined and often adamantly feminist women towards the upper end of the Indian class spectrum. It aims to deepen the understanding of employerworker relations and gendered domestic roles in contemporary Indian households. Previous literature on the middletoupper class employers of d

Amelogenin is an extracellular matrix protein which has an important role to play in enamel formation during tooth development. The need for amelogenin for research purposes in order to be utilized for its many potential applications have resulted in the rise of the production of recombinant amelogenin. So far, the most optimal expression system used for the production of recombinant amelogenin is
