Air pollution in urban environments exhibits large spatial and temporal variations due to high heterogeneous air flow and emissions. To address the complexity of local air pollutant dynamics, a comprehensive large-eddy simulation using the PALM model system v6.0 was conducted. The distribution of flow and vehicle emitted aerosol particles in a realistic urban environment in Malmö, Sweden, was stud
Changes in the net carbon sink of boreal forests constitute a major source of uncertainty in the future global carbon budget and, hence, climate change projections. The annual net ecosystem exchange of carbon dioxide (CO2) controlling the terrestrial carbon stock results from the small difference between respiratory CO2 release and the photosynthetic CO2 uptake by vegetation. The boreal forest, an
Many migratory animals use daylength, or photoperiod, to signal when to migrate and transition between annual phenological states. Whether animals use photoperiod as a temporal or spatial cue while migrating, however, requires additional empirical support. We used hatch-year dunnocks, Prunella modularis (a songbird), caught during their first migration in southern Sweden to elucidate whether migra
We are daily moving in different landscapes for various reasons; sometimes we are looking for specific activities and sometimes just to move from one place to another. Common for this is the affect the landscape can have on us and how it gives us different experiences. In this essay I seek answers to what is important for people when they visit the nature for recreational purposes. What factors do
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
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
As the demand for eco-friendly alternatives to traditional plastics grows, Polyethylene Furanoate (PEF) emerges as a promising solution. Derived from renewable biomass sources, PEF embodies sustainability principles by reducing reliance on finite resources and minimizing environmental impact. PEF is synthesized from 2,5-furandicarboxylic acid (FDCA), a key monomer which upon polymerization has the
I Sverige finns många förorenade områden med klorerade lösningsmedel och Färgaren 3 i Kris-tianstad är ett av dem. Där har tidigare legat en kemtvätt som använt sig av PCE (Tetrakloreten), där spill och läck-age har förorenat stora delar av fastigheten. PCE och dess metaboliter har en tendens att förorena stora volymer, vilket gör dessa ämnen svåra att sanera. Detta mastersarbete inriktar sig på a
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
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
