Förorenar Arktiska samhällen sig själva och påverkas marina organismer i samband med detta? Ja, bara i Adventfjorden och Grønfjorden på Svalbard finns förorening från lokala källor för 14 av 57 analyserade flamskydds- och ytbehandlingsämnen i sediment. Inte så mycket tänker kanske du? Men den största anledningen till förekomsten av dessa ämnen är utsläpp av orenat avloppsvatten och läckage från sMost of the ecotoxicological research conducted in the Arctic until today has focused on long range transport of pollutants, while fewer studies on local pollution have been published. The aim of this study was hence to investigate if local pollution of organophosphorus flame retardants (OPFRs), polybrominated diphenyl ethers (PBDEs) and perfluorinated alkylated substances (PFAS) occurs outside tw

Introduction: Asthma is a chronic inflammatory lung disease, which are associated with airflow obstructions. Asthma exacerbations are commonly caused by respiratory viral infections and lack efficient treatment options. Rhinovirus-induced exacerbations have been characterized by occurrence of necrotic cells, which may cause pathogenic effects. We hypothesized that house dust mite (HDM)-induced all

The long-distance migration that some animals accomplish can be truly astonishing. It can be observed in several different groups of animals with some of the most famous examples being sea turtles, birds, salmon and the Monarch butterfly. How these animals manage to navigate over distances sometimes as long as 10000 km nobody knows for sure. There is evidence of some animal’s ability to navigate u

Hegemonic European discourses about muslim*women reduce the complex living realities of muslim*women to the singular of the gendered and racialized other. This thesis investigates the hegemonic functioning of these discourses and explores postcolonial and queer theoretical approaches for dismantling it. Employing Mouffe and Laclau’s discourse analysis newspaper articles from seven European countri

Methods of poverty eliminations are some of the most researched subjects in development, as well as, public economics. Procedures in which poverty is believed to be best fought have, and will continue to, deviate across countries. In this thesis, the linkages between poverty, elementary macroeconomic variables and cash benefits will be examined. To explore the direct as well as indirect effects on

Most previous research on foreign aid has examined the links between aid and economic growth, with tenuous results. I endeavour to estimate the impact of health aid on the health level in the recipient country, proxied by the change in the infant mortality rate, as well as examine what other country-specific factors that affect the efficiency of health aid. My results are in line with my hypothesi

DivIVA, ett protein med spetskompetens Streptomyceter är jordbakterier som bildar mycel medförgrenade hyfer mycket likt hur många svampar växer. Bakterierna i detta släkte är kända producenter av antibiotika och omkring två tredjedelar av all antibiotika tillgänglig idag produceras av streptomyceter och deras släktingar. Förutom deras produktion av antibiotika så har streptomyceterna en unik livsStreptomyces species are filamentous bacteria from the phylum Actinobacteria in which cell elongation occurs at the poles of the cell. This differs from many other bacteria like Escherichia coli where cell elongation occurs by insertion of peptidoglycan in the lateral wall. An essential protein for polar growth in Streptomyces is the coil-coiled protein DivIVA. DivIVA has an essential role in orch

Income inequalities in developed nations are increasing and the issues of cause, effect and long run implications are currently being discussed and explored by economists and policymakers around the world. This thesis adds to the discussion by exploring income growth in Sweden; a country known for its equality and egalitarian society, yet has become one of the countries where income inequality is

Adopting a methodology similar to Bali, Peng, Shen and Tang (2014), this essay investigates whether stock-level liquidity shocks predict future returns on the Swedish stock market. Liquidity is measured by the relative bid-ask spread. Portfolios with stocks that experienced positive liquidity shocks yield higher returns than portfolios with stocks that experienced negative liquidity shocks. The me

Use of stem cells from fat tissue for clinical application Stem cells isolated from fat tissue (Adipose Stem Cells, ASC) are desired therapeutic agents due to their good accessibility, high yield, ease of isolation, and their growth and differentiation capabilities. Under long-term in vitro culturing, cells lose their capabilities to grow and divide, and acquire an aging (senescent) morphology. S

This thesis applies a model for optimal top taxation rate on all Scandinavian countries. The starting point is a theory by Saez, Piketty and Stantcheva limiting the possible change in behavior of taxpayers into three channels; labor supply, tax avoidance and compensation bargaining. I show that optimal top taxation rate depends on these three key elasticities and how they affect the tax system. Th

Habitatkonnektivitet och förekomsten av gräsmarksfjärilar Dagens gräsmarker har ofta reducerats till små, geografiskt isolerade fragment omgivna och åtskilda av stora arealer med planterad skog eller åker. För gräsmarkslevande fjärilar utgör långa avstånd mellan livsmiljöerna ett stort hot då det innebär kraftigt försämrade spridningsmöjligheter. I den här studien har graden av habitatkonnektiviThe biologically important grasslands of today have due to last century’s major changes in land use often been reduced to small, geographically isolated fragments. The low level of habitat connectivity in fragmented landscapes, prevents dispersal of organisms and is considered to be a great threat to biodiversity. In this study the impact of connectivity on the abundance of 6 species of grassland

This study has investigated the adaptation ability among Swedish public institutions with the intention of contributing with an understanding of the governmental and institutional approach on how they are supposed to manage potential larger-scale relocation due to climate change in the not so far reaching future. My specific research objective was to study the case of adaptation ability among ins

This case study of the effectiveness of the usage of Japanese role language uses character portrayals from performances by the theatre company Takarazuka Revue to investigate how native Japanese speakers perceive characters solely based upon lexical or grammatical cues in spoken language. With a foundation in Satoshi Kinsui’s description of role language and Christopher Vogler’s character archetyp

Climate governance is diversifying as the traditional multilateral approach is complemented by more autonomous and experimental reactions. The aim of this thesis is to enquire into this new kind of climate governance. Through a comparative case study of two urban climate change experiments in Denmark, the thesis first explores mechanisms that aid and hinder the achievement of experiment objectives

Over the last decade, financial disclosure and its impact on equity markets has increasingly become an area of interest. Firms suffering from poor operating performance have been shown to disclose bias earnings estimates as a means of evading negative market reactions. In this thesis, we attempt to discern whether managers purposefully bias their earnings estimates in periods of credit quality det

This paper investigates whether countries can use tax-based forms of capital controls to affect the share of foreign direct investment (FDI) relative to debt. Doing so might enable a country to influence capital-recipient countries’ foreign capital towards FDI and away from debt. The empirical model and dependent, explanatory, and control variables have been drawn from existing literature and have

This bachelor thesis studies fashion photographs where drag queens are participating as models. It was aimed to explore how their function in the fashion context can be seen. Three cases from 2016, all from a North American context are used for the study. “Caged Heat” from Interview Magazine no. 3, 2016 where Violet Chachki can be seen as one of the models. “Walk in the Wild Side” from ODDA Magazi

3D-cellodling - ett steg närmare verkligen Den traditionella odlingen av celler sker i Petriskålar/flaskor. Detta system har varit och är fortfarande ett bra verktyg för att få en riktlinje och förstå hur celler, däribland även cancer celler, svarar på t.ex. behandlingar av olika substanser. Begränsningen med detta system är att cellerna växer i 2D, d.v.s. bara i ett lager bredvid varandra. Men i
