Public Relations in the Creative Industries: Networks in the Limelight

Networking has been found to be ever more important in the economy of today’s globalised world. In recent years, public relations has started to pay attention to the process of networking and network theories. A branch which is understood to be based on networks and which is at the centre of current economic processes is that of creative industries. Creative industries consist of a diversity of sm

The influence of astrocytes and their culturing environment on blood-brain barrier modeling in a microfluidic chip

The blood-brain barrier (BBB) is a highly selective barrier separating the brain from the circulatory system. The physical barrier is built up by a monolayer of endothelial cells, which is the main component used for in vitro modeling. To create more physiologically relevant in vitro models, the field of organs-on-chips has recently been introduced, combining microfluidics and microengineering to

The thesis aims to test the hypothesis if PPGIS is more effective as a public participation method. The thesis first evaluated the two me

Ljud, oljud & tektonik

I takt med urbaniseringen och teknikens utveckling har ljudvolymen i våra städer ökat och idag utsätts omkring 2 miljoner svenskar för buller i sina hem. Trots att forskning har visat att långvarig exponering för buller är hälsofarligt har buller fortfarande inte någon större prioritet i planering av bostäder. Detta projekt syftar till att undersöka hur bostäder kan utformas för att dämpa obehagliAs urbanization and technological development progress, noise in cities increase. Today, 2 million swedes are exposed to noise in their homes. Despite scientific studies showing that prolonged exposure is unhealthy, sound is not a highly prioritized subject in the planning of residential architecture. The primary purpose of this project is to investigate how residential buildings can be designed t

Comparative tissue distribution and depuration characteristics of copper nanoparticles and soluble copper in rainbow trout (Oncorhynchus mykiss)

The continuously growing number of products containing nanoparticles makes their presence in the environment seem inevitable and given the well-known toxicity of dissolved metals, concerns regarding the toxicity of metal-based nanoparticles have been raised. Whether metal-based nanoparticles present similar or different toxicological effects compared to metal salts is a progressing field. In the p

Utvärdering av marknaden för solel i Irak – tekniska och ekonomiska aspekter

Elförsörjningen som till huvuddel kommer från fossila bränslen uppfyller vanligen inte efterfrågan i Irak. Samtidigt som det finns goda förutsättningar och stor potential för att installera och utnyttja solel som en lösning för den bristande elförsörjningen men med omtanke som värnar om miljön. Idag har cirka 20 procent av den irakiska befolkningen ingen tillgång till el, de återstående 80 procentThe main supply of electricity from fossil fuels does not usually meet demand in Iraq. At the same time, there are good conditions and great potential for installing and utilizing environmental friendly electricity from solar energy as a solution to the lack of power supply. Today, about 20 percent of the Iraqi population has no access to electricity, the remaining 80 percent have no continuous el

The Contractualization of Human Rights - State-Investor Contracts in the Agri-Business Sector

An increase in large-scale agricultural investment in land has been going on since the global food crisis in 2008. Import-dependent countries have acquired large plots of land to secure food supplies. The investments had disastrous impacts on the local communities living on the land before the investment took place. Many have been expropriated and evicted from their lands, affecting their human ri

System design of a DC based micro grid - A comparison study on the Andaman Islands

The world today stands at a cross roads when it comes to energy and electrical grids. A large part of the worlds population still lacks access to reliable working electricity 24 hours a day. Much of this is in remote and poor parts of the world. For much of the 20th century large centralized AC grids have been the norm to provide people with electricity. But for remote parts of the world including

Effects of ω-3 and ω-6 fatty acids

Abstract: The importance of dietary fatty acids (FAs), in particular omega-3 and omega-6 polyunsaturated (PUFAs), for immune system functions has been recognised and well-studied in mammals over the last decades. Recent studies suggest that similar positive/negative (e.g. strengthened/weakened immune com-petence) effects can be present in avian species. In this study, I explored these effects of ω

Det utsatta subjektet - Den separatistiska diskursen på Makthavarna

Framväxten av separatistiska organisationer för rasifierade i Sverige har periodvis erhållit stor uppmärksamhet. Förespråkarna ser det som ett sätt för strukturellt underordnade att stärka varandra, medan belackarna ser det som begränsande och destruktivt. Förståelsen för hur diskursiva praktiker struktureras inom separatistiska rörelser är emellertid begränsad. I denna studie har en diskursanalys

Little flying microalgae, who are you? - Taxonomy determination of airborne microalgae monocultures

Små flygande mikroalger – vilka är ni? Mikroalger är små encelliga fotosyntetiska mikroorganismer (1–500 μm i diameter), knappt synliga för ögat. De finns precis överallt omkring oss, i luften vi andas, i vattnet vi dricker och på våra husväggar. Det är inte mycket vi vet om dessa små mikroorganismer. Några av dem är luftburna, vilket innebär att de kan sprida sig långa sträckor med vindpustar fr

Unfolding the role of Ire1 and DNAJB1 in Parkinson’s disease

Hur kan cellers försvarsmekanismer hjälpa oss förstå Parkinsons sjukdom? Parkinsons sjukdom är den andra mest vanliga neurodegenerativa sjukdomen i världen, och under sjukdomens gång dör allt fler hjärnceller vilket leder till svårigheter för hjärnan. När fler och fler celler försvinner, får hjärnan problem att kontrollera de signaler som den skickar ut till kroppen, vilket leder till symptom somParkinson’s disease (PD) is a movement disorder of the brain which is hallmarked by the presence of large protein-rich cytoplasmic aggregates, called Lewy bodies (LBs), in the neurons. The protein α-synuclein (α-syn) is abundant in these aggregates, and can itself form aggregates. Several mutations linked to α-syn are also linked to an increased risk of contracting PD. In healthy neurons, the chap

The Search Continues -Problems of finding a consistent performance measure for Hedge Funds

The question of whether the choice of performance measure (PM) matters when evaluating Hedge funds has for a long time been subject to debate . This study explores the same question with a sample of individual monthly data from 669 Hedge Funds over a 10 year period. The standard rank correlation tests usually applied when studying the topic yield weaker correlations between the PM:s in our study t

Risk-Managed Momentum in Europe

This thesis sets out to evaluate a risk-managed momentum strategy in the European stock market. The recent performance of momentum in Europe is first evaluated. A momentum premium still exists in Europe but the strategy suffered large losses in 2009. A risk-managed momentum portfolio is created by dynamically scaling the exposure to momentum based on a monthly volatility forecast. The risk-managed

Pro-inflammatory cytokine regulation by the immunomodulatory protein p33

p33 as a potential novel therapeutic target in inflammatory diseases Inflammation is a condition usually triggered by infection of invading pathogens such as bacteria or viruses in the body. This invasion is quickly recognized by specific receptors localized on the membrane of cells, ready to sense these so called “danger” signals or foreign material. These receptors are part of the innate immuni
