This master thesis has been done in cooperation with Sweco Viak AB in Sundsvall. The aimwith the project is to investigate the purifying effect of percolation filter due to iron andmanganese. The overall goal was to investigate how the parameters surface load,sandfractions, and burden time affect the purifying effect. The expectation is to optimize thedesign and find a demouldning of the filter that gives sufficient purifying with a highersurface load. As an attempt to accelerate the curing of the filter, experiments with a layer ofsand which surface has been covered with manganese ore (MnO2) on top of the filter havebeen done.As test filters 10 L bars were used and the experimental work was performed at thewaterworks in Hassela and Munkbysjön.In Hassela different sandfractions were tested.

This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

Each year, Heterobasidion spp. is a major cause of economic losses to forestry in the northernhemisphere, including Sweden. New results indicate that pre?commercial thinnings could be at riskfor Heterobasidion spp. infections.

The aim of this paper is to analyze and problematize the content in the teaching media Känslan för ord through an integrative perspective. This is done by using two sets of questions based on two of the didactic questions what and how. How is the content of the Swedish subject constructed in Känslan för ord? and How is this content integrated in Känslan för ord? The used material consists of a fairly large amount of literature which provides different approaches, priorities, and methods about the Swedish subject. This literature forms the base for the model used to analyze the course books.The results are based on an analysis of the exercise culture (uppgiftskultur) in the two books and are extensive.

The objective of this study was to contribute with suggestions of nature preservation managements of selected forest objects of high nature values managed by the Swedish state-owned forest company Sveaskog. Many forests with high natural potential are relatively rare today due to modern forestry, where wood production is the main purpose. Sveaskog?s policy is to consider and to priority nature conservation on valuable objects. This assessment includes objects that in the future may develop into nature reserves.

The research of this Bachelor?s thesis examines classifieds for librarians, and makes use of Ørom?s theory of sixlibrarian identities plus Schreiber?s complementary seventh identity. The main focus of the thesis was to examine what qualities and skills are presented and what identities are manifested in the classifieds. A third issue was to explore how relevant Ørom?s theory is to examine and understand the profession today.The data was analysed by the use of content analysisand a hermeneutics approach was taken.

?Facebook has become as natural as having a phone? The use of social media in three libraries in the Umeå region ? an evaluationSocial media has come to be an integral part of people?s everyday life, as well as the business world in terms of communication and marketing. More and more libraries also embark in the use of social media, and the purpose of this study is to evaluate the use of social media in three libraries in the Umeå region. The libraries all use Facebook as their current, primary social media. Thus this study focuses partly on the analysis of the content on each library?s Facebook page, and partly on the experiences of the responsible librarians. The evaluation is based on a mix of existing tools in evaluating social media that are relevant in a library context.

In order to answer the question in the title, a cross-cultural analysis of two countries was done. Countries chosen were the Republic of Latvia and the Kingdom of Spain. The need for this research was suggested by increased cross-border business activities inside the European Union, and the lack of previous studies involving new Member States. The aim of the research was to see what environmental factors influence advertising adaptation in the European Union, as well as to evaluate the applicability of a standardisation approach. According to the theory, there are three external factors that influence the creation of a global advertising.

This bachelor thesis is titled Who is an extremist?  - A qualitative content analysis of the agglutination of right- and left-wing groups and is written by Måns Hoffsten within the discipline of political science. This essay aims to illuminate in which way the Swedish government has tackled extreme forms of left-wing and right-wing activism during the period 1980 ? 2013. By looking at how governmental policy-suggestions and reports concerning extremism are formulated during this period this essay explores when and how the two groups first started to become a part of the same problem-representation and on what premises this is built.

The purpose of this Masters thesis is to investigate if gender stereotypes are mediated to children between 0-3 years through books suitable for their age. This thesis concerns books that are available in public libraries. The content will be analysed by using a combination of methods, both content analysis of all the books in our study and a qualitative analysis of a smaller number of these books. With inspiration from both Robert Connell and Yvonne Hirdman and their theories of gender and gender stereotypes, this material was read and we wanted to examine if books for very young children might establish stereotypes. Our analysis showed that many known stereotypes are common in these books.

This study is about gender stereotypes that occur in the magazines of ELLE and KING's advertisements in 2014. The purpose of this inquisition is by using a gender perspective to examine the interpretation of women and men, compare how they relate to the traditional gender stereotypes. To answer our purpose of this study, a selection of 400 advertisements were analyzed based on it's content and visual expression. Through a content analysis, we could measure the frequency of 18 variables and put them in relation to each other to grasp the differences that exist between the genders. The results are presented in bar charts based on the variables that proved most interesting outcome between the genders.

Methicillin-resistenta Staphylococcus aureus (MRSA) har blivit en allt vanligare patogen inom sjukvården och i samhället. MRSA orsakar infektioner som inte kan behandlas med ?-laktamantibiotika. För att förhindra spridning genomgår patienter och sjukvårdspersonal screening-tester. I dessa screening-tester ingår PCR-analys av mecA, nuc och/eller Sa442.

The idea of using algae in different areas and exploring its possibilities is nothing new. Already in the early 1950s microalgae was explored as a possible food resource because of its high protein content. Lately there has been an increased interest in its potential for industrial use. Wastewater treatment is a possible use of algae since the algae grow well on the nutrients present in the water. This offers the possibility to grow algae for nutrient reduction and use the biomass for energy or animal feed since many alga species has a good nutritional value. Approximately 800-1000 m3 water is applied per 1000 m2 of greenhouse area during one season in a tomato production.

Textbooks are the most dominant literature used in schools and are therefore an important source of information. Consequently, it is crucial that these are not misleading or biased and maintain a high quality along with a strict concordance to the School Department?s curriculum. The aims of this study have been to examine how Mormons, Jehovah?s Witnesses and Hare Krishna are presented in four religion textbooks used in senior high schools, as well as to examine what type of knowledge is being presented in terms of epistemology.
