Försurning och övergödning utgör betydande hot mot världens ytvatten och svenska vatten är bland de mest utsatta. I den här studien har avrinningsområdet Storskogen analyserats för att undersöka sambandet mellan atmosfäriskt nedfall, hydrologi och ytvattenkemi. Med atmosfäriskt nedfall menas de luftburna föroreningar som landar på avrinningsområdet antingen för att de fångas upp av trädkronorna eWater 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.

Järn är essentiellt för livet som vi känner det idag. Det är en del i flera av de huvudsakliga energisystemen som finns i de flesta levande organismer. Men järn som är fritt i en cell kan orsaka enorma skador genom att det deltar i en process som bildar så kallade syreradikaler. Det finns därför en mängd olika proteiner som på olika sätt binder och reglerar järn. Fel med dessa proteiner kan leda tFriedriech'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

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

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

MicroRNAs (miRNAs) är små, enkelsträngade RNA molekyler som består av cirka 22 molekylära byggstenar, nukleotider. Nukleotiderna består antingen av adenin (A), guanin (G), cytosin (C) eller uracil (U). Dessa små RNA molekyler är involverade i flertalet sjukdomar och genom att hitta sekvensen av dessa A, G, C, T i ett biologiskt prov, kan miRNAt agera som markör för att hitta nya behandlingsmetoderMicroRNAs 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

Vid marktekniska undersökningar i finkorniga jordar är det av stor vikt att korrekt kunna bestämma den odränerade skjuvhållfastheten. Detta görs idag vanligtvis ute i fält med en uppsjö av sonderingsmetoder som ger olika mått på hur fast jorden är. För homogena leror och sand finns det en stadig empirisk grund för hur dessa sonderingsparametrar räknas om till odränerad skjuvhållfasthet, men hur seThe 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

III-V semiconductors are a profound part of the optoelectronics industry and new developments in alloy compositions and architectures are constantly emerging. Lowdimensional semiconductors, such as nanowires (NWs) have shown to have improved characteristics in certain areas such as enhanced light absorption and can furthermore be integrated on Silicon (Si) plattforms and are thus predicted to be a

Det övergripande syftet med detta examensarbete är att sammanställa en utvärdering av de utmaningar som det innebär att arbeta med utländsk arbetskraft på svenska byggarbetsplatser. Vidare ämnar arbetet också kartlägga huruvida huvudentreprenörens arbetsledning påverkas av arbetssättet. Studien initierades med en litteraturstudie för att få en utökad teoretisk bakgrund. Vidare genomfördes en fall

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

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

Denna studie har strävat efter att undersöka hur högerorienterade digitala alternativa nyhetssidor i USA porträtterar politik i sin nyhetsrapportering. För att undersöka detta har studien utfört en kvalitativ gestaltningsanalys av hur två av USA:s största högerorienterade alternativa nyhetssidor, Breitbart News och The Daily Caller, rapporterade om riksrättsprocessen mot Donald Trump inom tidsrameThis study has aimed to investigate how “right-wing” alternative media news websites in the United States frame politics through their news reporting. To determine this, the study has conducted a qualitative framing analysis of how two of the United States’ major right-wing news websites’, Breitbart News and The Daily Caller, reported on the impeachment process against Donald Trump within the time

Our decisions from the past affect the present time. The same is true of the decisions we make today. How do we want to see our local environment in the future? In the western part of Iceland there is an island called Brákarey. Brákarey is connected via bridge to the town of Borgarnes. Brákarey has played a variety of roles over the past years, but transport of people and goods was one of its bigg

This thesis investigates how place can be understood through assemblage theory and what that implies for the understanding of human relation to place. The framework has been widely used outside and within human geography, at a few instances related to place. Exploring place as assemblage is done through a case study of S:t Pauli cemeteries in Malmö. Main methods are walk along interviews and obser

Nowadays it has become relevant for scientists to understand the impact of tropical forest structure on the Global Carbon Cycle. Dynamic vegetation models have been developed to pursue this issue, specifically by improving algorithms that could analyze the allometry, biomass content and mortality rate of each singular simulated plant individual and how this responds to climate change, management aCompetition between neighbouring trees has a big impact on their growth. Trees have different strategies to deal with competing neighbours. Some grow quickly and tall, overshadowing neighbouring trees, but die young (Georges K., 2015). Others grow more slowly, but outlive the fast-growing ones and cast shade on them over a longer period. These interactions have a strong influence on the dynamics o

All around the world is the form of the built environment playing a significant role in either enabling or inhibiting outdoor activities. When it comes to winter and Winter cities, it is a challenge how to enable and encourage outdoor activities and soft mobility as the harsh conditions often make it uncomfortable to spend longer periods of time outdoors. A major urban design challenge in Winter

Due to a warming climate, tundra ecosystems are subject to shrub and treeline expansions which could lead to increased above- but decreased belowground carbon (C) stocks. An observed low soil C stock in some subarctic forests and tall shrublands has been suggested to be induced by priming of organic matter decomposition, possibly mediated by ectomycorrhizal fungi. On the other hand, the higher bel
