Organisms in the aquatic environment face the challenge of exposure to environmental pollution by a multitude of pharmaceuticals. However, the potential for disruptive effects in non-target aquatic organism remains poorly understood. Fluoxetine is one of the most commonly prescribed psychoactive drugs and it has been shown to bioaccumulate in fish, and potentially affects a broad suite of importan
The settlement of marine organisms on boat hulls – known as biofouling – is a major concern in boating and over the years more or less environmentally harmful substances have been used to prevent it. However, the concept of biocide-free, so called foul-release coatings (FRC) that change the surface properties of the boat hull has gained more attention recently. In the present literature study, I h
In this thesis I have attempted to explore flexibility of work outside the sectors which are most often associated with the concept of flexibility in ‘the new economy’, e.g. work in ICT-sectors. Through a case study of cleaners and cleaning work in Sweden I have attempted to discuss both how flexibility is represented and how consequences of flexibility can be understood in relation to experiences
Försäkringsrätten är till sin karaktär väldigt speciell eftersom avtalsförhållan-det rör de två primära avtalsparterna, men också övriga premiebetalare. Både genom utfallet men också genom bedömningen som sedermera blir vägle-dande för övriga försäkringstagare. En variant på försäkring är den allomfat-tande allriskförsäkringen, som till sin karaktär ska vara mer heltäckande än en reguljär egendomsInsurance law is inherently unique because the contractual relationship primar-ily involves two main parties but also impacts other premium payers. This occurs both through the outcome of disputes and through the interpretative precedents established, which subsequently guide other insurance holders. One form of insurance is the comprehensive "all-risk" insurance, designed to be more inc
De flesta vattenlevande organismer på Jorden lever i en miljö där de samtidigt måste hantera flera olika hot och stressituationer, såsom t.ex. predation, klimatförändringar och brunifiering. Trots relativt god kunskap om varje stressfaktor för sig, vet man förvånansvärt lite om hur synergier av samtidigt förekommande hot påverkar organismer. Därför har jag i min avhandling undersökt hur predation,Most organisms on Earth live in an environment where they are exposed to multiple pressures, including predation and climate change. In many aquatic ecosystems, organisms have to handle additional challenges such as brownification, co-occurring with climate warming. Despite the growing recognition of impacts of climate warming or brownification on the freshwater communities, little is known on how
In our homes we enjoy daylight reaching the rooms through the windows, and artificial lighting when there is not enough daylight available. Electrical lighting has been used in Western homes since the late 1910s. We have experienced the technical development from warm incandescent light bulbs to energy-efficient light emitting diods (LED). In Sweden we lack daylight in winter and have a lot of day
This study focusses on the urban infrastructure for water supply in Roman Pompeii. The water distribution network of lead pipes was constructed inside the city walls, at the time when the city was connected to an aqueduct. Life for the Pompeiians changed considerably when aqueduct water started running continuously in street fountains all around the city. The study is based on previous research an
This study is an initial attempt to describe the established French loanwords in the lingua franca Sango, which is the main language spoken in the Central African Republic (CAR). It is a second language for the majority of the population of 3 million people for whom a great number of vernaculars serve as first languages. French loanwords in Sango are prompted by the contact between Sango and Frenc
Syftet med denna uppsats är att undersöka hur Europeiska Unionens (EU) lagstiftning avseende saluföring av utsäde av köksväxter påverkar mångfalden av växtgenetiska resurser samt att utreda potentiella förbättringsförslag till den nuvarande lagstiftningen. EU:s utsädeslagstiftning består främst av direktiv 2002/55 som anger att enbart certifierat utsäde från registrerade sorter får saluföras i EU The main purpose of this essay is to investigate how the European Union’s (EU) vegetable seed marketing legislation affects the diversity of plant genetic resources and to examine possible improvement to further this diversity. The EU seed legislation consists of directive 2002/551 which provides that only certified seeds from registered varieties may be sold in the EU, and of directive 2009/1452.
Min kandidatuppsats fokuserar på att analysera vilka möjligheter det finns att förena vinstsyftet enligt 3 kap. 3 § aktiebolagslagen med hållbarhet. Både hållbarhet och vinstsyfte är viktiga aspekter. Det är svårt att kombinera de två aspekterna i ett aktiebolag då vinstgenerering är det man strävar efter, detta kan leda till kollision med hållbarhetsaspekter. I det andra kapitlet ligger fokuset p
In recent years, there has been a growing scholarly interest in the cultural and political significance of joyful, positive and nostalgic memories and forms of remembrance. Without downplaying the role of trauma and oppression in the mnemonic makeup of contemporary societies, memory scholars have increasingly pointed to the co-existence, or parallel existence, of brighter recollections of the past
En av de vanligaste frågorna som brukar ställas till astronomer är om det finns liv någon annanstans i universum. Vi har ännu inget enkelt svar. Framsteg mot ett svar på denna fråga görs lite i taget. Den här avhandlingen är ett av dessa steg.Min forskning är inriktad på atmosfärerna hos så kallade "ultra-hot Jupiters": planeter i Jupiters storlek som kretsar så nära sina stjärnor att de hettas up
The present essay focuses on the figure of Maurice Bucaille and on his contribution to the discourse on Islam and science. Its purpose is twofold. First of all, it aims to provide the reader with a concise map of the ideas of the French author, reconstructing their core and their interrelations. Furthermore, it aims to question what I define as the apparent naivety of Bucaille's work, a reason why
As a global society we are entering an era where land areas and land-based resources are coming to the fore once again for capital accumulation and economic growth, for the first time since the end of the 18th century when Malthus forecasted a contradiction between population growth and agricultural output. That constraint on economic growth, imposed by limited land areas, was overcome by the comb
This thesis concerns vascular endothelial growth factor (VEGF) and its possible role as a neurotrophic factor. I have investigated the effect of VEGF on neurons in culture but also in vivo, following a crush lesion of the sciatic nerve, and following nerve repair. Attempts were also made to unravel the mechanism by which VEGF affects neurons and Schwann cells, using a pharmacological approach in c
The gold-bracteates from the migration period are circular medallion like objects with a diameter of about 5 cm. The production began at approximately AD 450 and came to an end at about AD 550. Thus the bracteates were in use for a period of a hundred years. This dissertation focuses on the iconography of the so called C-bracteates. The motifs of the C-bracteates depicts a human head over four leg
