During the years of the so-called refugee crisis, migrants lacking access to housing in Greece have squatted buildings or resided in makeshift settlements. Those homes have been met with state violence and continuous evictions. Those evictions are a form of migration control in the context of an ongoing disciplinary ‘management’ of migrant populations and their mobility in Europe and Greece. The t
As the air quality in urban environments is a rising problem, a deeper understanding of how air pollution is dependent on different factors is necessary. In these environments, there are different parameters that effect how the chemical reactions of the pollutants are proceeding. Here the parameters solar radiation, temperature, humidity, emission factors and background concentrations of gaseous a
Engine development for reduced fuel consumption and for the ability to use alternative types of fuels is required as emissions and the limited access of petroleum are issues coupled to diesel engines. Experimental testing is in many cases insufficient and expensive in comparison with simulations for engine development. This thesis is focused on extending a model of a diesel compression-ignition en
Dutch disease is one of the mechanisms through which the boom in one of the sectors induced by an exogenous shock may have profound adversary implications over the economic growth in the long term. The windfall gains generated from the commodity price increase leads to real exchange rate appreciation boosting wages and prices across all economic sector. As a result, economic growth becomes unsusta
Coastal erosion has increased worldwide during the last decades, mostly due to human activities. Vietnam is not spared, where many places within the country suffer from beach erosion. This report focuses on the region around Thu Bon river mouth in the central part of Vietnam. The beaches next to the river mouth are experiencing severe erosion, especially Cua Dai Beach. The beach is totally eroded
During the last decades, increased concentrations of natural organic matter (NOM) and colour of surface waters have been reported from northern Europe and North America. Since surface waters are widely used for drinking water production this development has been problematic for drinking water producers. Even though NOM in itself is not harmful, it can cause production of undesirable disinfection b
The aim of this study was to model the impacts of climate change on potential geographical distribution of Prunus africana in the Eastern Arc Mountains of Tanzania. Maximum Entropy modelling was used to construct species distribution maps for P. africana to determine relative contribution, and effects of climate change on the potential geographical distribution of P. africana based on climatic sce
The dissertation examines the underpricing of sponsor-backed (private equity backed and venture capital backed) and non-sponsor backed initial public offerings (IPOs) listed on all US stock exchanges between January 1997 and December 2017. The authors identify 403 PE-backed IPOs, 179 VC-backed IPOs and 1469 non-sponsor (non-PE and non-VC) backed IPOs. Evidence suggests that PE-backed firms are lar
The relevance of credit ratings has seen augmented growth after the financial crises, especially in the Eurobond market, even though U.S. agencies have been criticised whether ratings are relevant information sources for international capital markets and if non-U.S. market participants relate their investment decision on the ratings. This paper is concentrated on the association between changes in
This paper investigates differences in perception of leadership and well-being between guest workers and native workers in Sweden. Guest workers are individuals who take up temporary employment in a foreign country. While previous research has found cultural differences in well-being, there is limited research investigating the well-being of guest workers in a host country. Similarly, previous res
We investigated the performance of basic jet subtraction, by the utilization of jet reconstruction generally used at the Large Hadron Collider (LHC). This was done by studying Z-bosons, in the dielectron decay channel, and the associated jet correlation in pp, pPb and PbPb collisions, using datasets generated by the Monte Carlo generator PYTHIA8. The PbPb collisions at $\sqrt{s_{NN}} = 2.76$ TeV a
Exposure to airborne particulate matter has been declared to cause cardiovascular and respiratory disease as well as cancer. By understanding how the aerosol particles deposit in our respiratory tract, we can understand how the exposure to airborne particles affect our health. The health effects partly depend on which type of particles that we are exposed to, but also how sensitive we are as indiv
Control theory plays a big part in the development of more efficient and environ- mental friendly combustion engines. But the process of designing good controllers can be very time consuming and complex. One way to reduce the time spent on design and testing of a controller is to use simulations to get fast feedback of the controllers performance. Therefore, in this thesis it is investigated if a
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
The tumour microenvironment in Mantle Cell Lymphoma (MCL) is underexplored. Through advancing understanding, it would be possible to stratify patients to the optimal immunotherapy. To enable analysis of more complex phenotypes, compared to single immunohistochemistry (IHC) staining, the aim of this thesis was to evaluate the novel overlay-analysis tool in HALO® using diagnostic MCL. This novel mod
Today, Sweden is experiencing a significant pressure on the housing market. Most of the municipalities are facing a housing shortage, and the problem is especially acute in metropolitan regions. Currently, Sweden has one of the highest levels of urbanization in the EU and, taking into consideration the rising population, the lack of housing has become a national issue. Lund is a university town a
By betting on market downturns, short sellers make profits from asset declines. Thus, critics often blame short sellers for being responsible for market downturns and as a consequence, short selling restrictions became a popular phenomenon worldwide post the 2008 financial crisis. During the European sovereign debt crisis regulators in France, Belgium, Spain and Italy imposed a short selling bans
