Side effects of biological control agents in agriculture : does the bacteria Bacillus amyloliquefaciens affect the earthworm Aporrectodea longa?

Pathogenic microorganisms pose a big threat towards food production. Meanwhile, negative impacts on humans and environment are seen by the use of pesticides. Biological control agents are an alternative to the use of chemical pesticides, and plant-growth promoting rhizobacteria, such as Bacillus amyloliquefaciens has been shown to have good properties as biocontrol agents. Before these bacteria can be used commercially their impact on other soil organisms has to be evaluated. This thesis looks into what biocontrol bacteria are and how they might affect earthworms.

Offentlig upphandling : Skillnader i de obligatoriska kraven i större och mindre kommuner.

Recent years there has been discussed how the critical situation in the housing market threatens the Stockholm region's growth. The thesis objective is to examine whether there is a scientific link between the lack of housing supply and growth. The thesis also intends to identify solutions for increased housing construction, for instance by examining the conditions for a greater regional perspective and influence on the region's housing supply. The thesis empirical study is based on semi-structured interviews with representatives from the Government, municipalities and the housing industry.In Sweden, research on the relationship between housing shortages and growth has not been conducted to that extent it can be said to exist scientific evidence regarding the growth threat. However, in Britain and the U.S, empirical studies show that a lack of housing supply has hindered growth through negative impact on countries' gross domestic product.

Kriminella, offer, resurs, börda: Diskurser om ?papperslösa? i svenska dagstidningar

This qualitative study is focused on the way ?papperslösa? (undocumented/illegal/irregular immigrants) are portrayed in Swedish daily newspapers, what images are presented in the articles, what discourses permeate the text, what identities are being constructed, etc. The empirical data consists of thirteen articles published in Dagens Nyheter and Svenska Dagbladet (two of the biggest daily news papers in Sweden) during the period 2010-10-01 ? 2011-04-01, and I?ve used a type of discourse analysis called ?diskursanalys med inriktning på identitetskonstruktion? (?discourse analysis with focus on identity construction?), as the method to analyze the articles. The results of the analysis showed that four discourses and identities were constructed, re-produced and upheld in these articles.

Förmedling av skönlitteratur via bibliotekets webbplats

Mediation of fiction has always been one of the main tasks of the public library. The focus on information technology is often seen as a threat and competitor to this task. But technology can also offer new ways to mediate fiction, and the aim of this thesis is to examine how library websites and blogs can be used for this purpose. The research questions are:? What forms of fiction mediating material exist on library websites and blogs?? How is the fiction mediating material presented?? Are there any differences between the fiction mediating working methods on websites and blogs compared with those in physical libraries?The thesis is based on a qualitative content analysis of eight Swedish public library websites and three blogs, and on a theoretical frame work including literature and research on mediation of fiction, library websites and blogs, web design and usability.

Vi och dom : En granskning av hur hinduismen och buddhismen framställs i tre läroböcker för gymnasiet.

This paper examines how Hinduism and Buddhism are portrayed in three textbooks for an upper secondary school course in religion and is limited to a selection of books published in 2009. Based on a qualitative content analysis, the paper examines the extent to which there is an intentional division, that is to say a line between ?them and us? in the ways in which the religions are described, and to what extent the description of these religions in the textbooks are Eurocentric. The study focuses on whether or not there is a ?them and us? perspective in the different books and if so, the ways in which this approach is evident.The result of this study shows that traces of a ?them and us? perspective can be found in all three books.

Ljuslyktan Ballongen :  

During my final examination project, I have been working with a design process to develop a new set of candle lanterns for the company Sagaform AB. This company has a large and significant role on the Swedish interior design and retail market. The assignment was developed when the company stated that they would like to supplement and expand its existing range of products. The research and surveys I have done have helped me to create eight different concepts and one of them ready to compete with the existing candle lanterns on the market. The result of my concept proposal expected to be included in Sagaform?s 2013 spring catalogue. During the project I have developed 3D-rendered images, a physical model, and a solid foundation for making prototypes. The Balloon has an attractive design language that fits both every day and more festive events.

Avel för hållbar produktion

This essay intends to provide an understanding of the developments in the right of public access and recreational activities in the forests of Sweden, and which factors and prerequisites that have affected this development. The forest and its history, along with recreational development has in many ways shaped today?s rights of public access, but there is also an age-old tradition of public access that has affected how we have used the forest, and that also has enabled the development of outdoor recreation. Many are unaware of this, which causes misunderstanding to appear around the rights of public access and how it is supposed to be used.The essay opens with historical descriptions of public access, the Swedish forest and outdoor recreation, to thereby provide a picture of how these three fields have influenced each other over the centuries. This is followed by a description of the current access rights and the problems associated with those, and a description of other countries' equivalent of the right of public access.

Postkolonialistisk bildanalys av Hem- och konsumentkunskapsböcker

The Swedish education system reflects the multicultural society in Sweden, therefore there is a need of school textbooks that pupils can identify themselves with to create meaning and value in their learning. According to the Swedish Education Administrations (Skolverkets) report (2006) and Selander (2003, s. 198) the school textbooks are the main source of education in class. There has been an implicit message in the older textbooks that is associated with the belief that non-Europeans are "seen" as victims, and that Europeans are privileged with a "good life".Many school texbooks has been analyzed from different points of perspectives, however, analysis from a postcolonial perspective on home economics books has practically been nonexistent.Analysis in this study are focused on how non-western people are been portrayed in six different textbooks in the subject to conclude if the colonial discourse is still maintained and reproduced in the school. To answer the question of formulation an image analysis is made of the six, previiously mentioned, textbooks.

En geokemisk kartering över området kring Nasa silvergruva : Effekterna av historisk gruvdrift i svensk fjällmiljö

The aim of the study was to map the extent of Fe, Cu, Pb, As, Zn and S contamination in the area surrounding the Nasa silver mine. The mine operated between 1635 and 1810 with some prospecting performed in 1889, and has become infamous for the gruesome ways that the indigenous people were treated during the early years of operation. This study tested three hypotheses through a geochemical survey: 1) sulfide oxidation is still active in the abandoned mine, 2) the soil downslope of the mine is contaminated by mine drainage, and 3) the stream downslope of the mine is affected in the same way. All three hypotheses were valid, as the results showed that still, >200 years after mining operations ceased, signs of the historical mining are clearly visible in the surrounding environment. Acidic conditions were discovered in surface waters close to the waste rock piles, which indicates active sulfide oxidation.
