Small pieces of plastic, termed ?micro plastic? in the oceans derive mainly from degradation of big plastics such as beach littering, but also from sources of direct emission from e.g. beauty scrubbers and synthetic sand-blasting. These micro plastics are ingested by marine animals ? mistaking them for plankton ? or via prey.

Syftet med denna litteraturöversikt är att göra en utvärdering över de mekanismer som är viktiga vid tumörmetastasers nybildning av kärl s.k. angiogenes och med vilka metoder man kan hindra dem. Tumörceller som prolifererar ohämmat utan att stimulera angiogenes begränsas av brist på näring och ineffektiv bortförsel av slaggprodukter och kan därför sällan växa och bli större än cirka 1mm. Detta medför att även om det kliniskt finns många små metastaser i en patient så innebär det sällan något problem för patienten. Om tumörcellerna däremot muterar så att de kan stimulera angiogenes så tillåts tumörerna växa sig större och förstör då kringliggande vävnad vilket tillslut resulterar i patientens död. Mycket forskning görs i nuläget inom ämnesområdet och man har som mål att med hjälp av angiogeneshämmare göra cancer till en kronisk men hanterbar sjukdom istället för den sjukdom med dödlig utgång som den ofta är idag. Den första angiogeneshämmaren som godkändes för medicinskt bruk i USA var Avastin (Bevacizumab) som är en antikropp som binder till och oskadliggör vascular endothelial growth factor (VEGF), vilket är en av de faktorer som stimulerar angiogenes. Detta får som följd att de tumörer (60 % av alla humana) som uttrycker denna faktor hämmas i sin tillväxt.

This study examinates technology's traumatic impact on the male subject in The Atrocity Exhibition by J.G. Ballard. In my analysis I show how the protagonist uses a fetischistic strategy in order to make sense of the trauma that technology embeds. Paradoxically it proves to be the agent of his trauma, but also functions as his shield. The machine is thus in a position of the hinge, the point in a structural system that both enables and deconstruct the system.

Title: How do music students with different genre backgrounds perceive the same music? In this paper I report a study about how music students with different genre background perceive the same music. I let twentyone classical music upper secondary school pupils and twentyone rock music upper secondary school pupils listen to ten short music pieces of different character and styles. While listening, they were asked to answer four questions about which instruments they could perceive, what they could tell about pulse, rhythm and beat in the music, which component they thought was the most important in the piece and what word they thought best described the feeling of the piece. All four questions had to be answered for each piece of music to facilitate analysis of differences connected to genre background in those answers.

Purpose: The purpose of this thesis is to identify and analyze innovative products and services within the telecom industry, letting these findings constitute possible ways for CSPs to innovate the experience of their customers. Methodology: The research in this thesis was conducted from a qualitative approach and data were collected using primary- (expert interviews) and secondary sources (journals, articles, web sites etcetera). In addition, a research design entailing four sequential steps was created to stipulate and illustrate the logic underpinning the methodological process. Theoretical perspectives: The theories are divided in three groups. Background theories ? these intend to capture the problematic nature of the transforming telecom industry, examples of such theories are; value chain theories and ecosystem theory.

This essay in musicology is combined with a CD-recording of piano improvisations. Its purpose is, on the one hand, to examine some of the ideas permeating piano improvisation during the first part of the nineteenth century, and, on the other, to find ways to apply these nineteenth century ideas of improvising to modern piano playing. The artistic part of the work is as important as the theoretical, and the two strands are supporting and reinforcing each other.The first section of the text focuses on preluding ? that is, a genre of improvisation. The second section investigates some aspects of the improvising of Franz Liszt ? that is, different types of improvisation as practised by an important nineteenth century musician.

This project was aimed to study the degradation of polystyrene-butadiene-styrene block copolymer (SBS). SBS is used to modify bitumen, the binder in asphalt. From earlier studies it is known that SBS degrades in bitumen, but the degradation products have not been identified. To be able to determine the long term effects of SBS in the environment, degradation products need to be identified. Polystyrene forms rigid blocks with polybutadiene as a rubbery matrix between the ridgid blocks.

The Swedish parliament has decided that Sweden should increase its usage of renewable fuel sources to a level of 50% of the total energy consumption in Sweden by the year 2020. One way to reach that goal may be to increase the usage of stumps as a bio-fuel. In Sweden stump harvesting is possible on about 5-10% of the total harvested area and thus contribute with 1,3 - 2,6 TWh per year. An increase stump harvest doesn't come without its drawbacks for the environment. When harvesting stumps a tracked excavator is used to pry the stumps from the ground and then cut the stumps into smaller pieces.

Lattelement AB in Ornskoldsvik is one of the leading companies in Sweden in composite elements in walls, floors and roofs in particular. The company supplies elements to buildings located with a wide geographical variation, which means that the products are subjected to very different climate with regard to snow, wind and humidity. This places high demands and requires the elements to withstand large variable loads.The elements are made of lightweight beams with flanges of structural timber and beam webs made of OSB. These are bound together by nogging pieces with the same kind of structure. On top of the beams a nailed and glued plywood is added to absorb compressive forces and on the underside of the element a sheet of steel is added for tensile absorption.These elements are then attached to the building framework in different ways depending on the particular element height, loads and the structual supporting material of the frame work.

By studying a place or a phenomena research contributes to the creation of the image of the thing that he or she studies. Also, planning is seen as a democratic tool, a way to ?make? democracy. In order to see what democratic ideals that is being express it becomes important to study the research about democracy in Botkyrka. It is from this thinking this study about democracy and research has been formed.

Background: Studies showed differences in attitudes towards patients with mental illness in nurses who worked in somatic care compared to nurses who worked in psychiatric care. The nurses in somatic care stated more negative attitudes to mental illness in relation to the nurses in psychiatric care. Studies also showed that work experience affected attitudes towards mental illness. Nurses who often came in contact with people with mental illness had less negative attitudes and prejudices against mental illness. Aim: The aim was to examine the experiences from nurses in somatic care, caring for patients who also have a psychiatric diagnosis.

This essay is an attempt to study some post-modern theological positions with regard to their growing interest in the use of mystical theology and mysticism in theological research in the academic post-modern world, and to see if the 19th century theologian Albert Schweitzer couldprove a resource for this understanding of mystical theology. This position is known in the essay as ?the mystical turn.?To present the background and understanding of this post-modern view of mystical theology the essay presents three theologians, namely: Andrew Louth, Mark A. McIntosh and Sarah Coakley.These three theologians argue for the use of a contemplative and transforming mysticism as a postmodern epistemology in relation to theological research, with growing concern of the status of theology in the secular and post-modern world. Having made clear the views of these three theologians the essay then presents Albert Schweitzer's view on the mysticism of Paul.

The study focuses the evil within human beings and evil actions against other humans and the human kind. The evil is defined as evil actions such as murder and actions in war. The questions asked is whether the evil has a face and if it is possible in that case to paint that kind of face. The medieval mural paintings in old churches include Cain murdering his brother Abel based on the Bible. The study also includes reliefs, sculptures in stone describing Cains´s murder of Abel and sculptures with the Massacre of the Innocents in Bethlehem according to the Bible.

I started this project with the understandning that European hisory has become more important in government documents as a part in a larger European discourse, and that this fact is likely to be reflected in the chools textbooks. Therefore this essay deals with the task of comparing history textbooks over time trying to find changes. Firstly to find out how much space European history is afforded in the textbooks, and secondly how Europe is described and used in the textbooks. In my first task I will use a content analysis and in my second a conceptual analysis. My material consists of eight books and I have three pieces of older educational materials from the years 1949, 1954 and 1962.

Officially, the EU gender policy since 2000 has been guided by the strategy of Gender Mainstreaming. This strategy aims to promote gender equality and is informed by a feminist ontology which stipulates that women are structurally subordinated.In this essay, I examine whether the European Commission has adequately adhered to this gender policy in its free trade negotiations with the ACP (African, Caribbean, and Pacific) countries as part of the Cotonou Agreement. As a result of my text analysis of documents related to the negotiations, opinion pieces by interested actors and policy papers of the EU, I find that the Commission does not act in accordance to its stated gender policy.To explain this discrepancy between policy intent and actions, I employ postliberal feminist theory and Robert Putnam's Two-Level Game Theory Model. By analyzing statistics and published research, I explore how gender issues are being represented politically on a domestic and international level.My findings show that a key cause of this discrepancy lies in the low levels of female participation in the political institutions of the EU and ACP; a lack of participation that is especially pronounced in the area of international economics. In explaining the constraints on female participation and the prospects of full implementation of the EU's gender policy in the international political economy, I emphasize the role of culturally and historically gendered institutions..
