The aim of this thesis was to examine if it is possible to keep nitrogen in the form of nitrate(NO3-) in ponds from one season to another by keeping a high concentration of oxygen in thepond water. This hypothesis was tested by doing a lab experiment where two systems werecompared according to nitrate concentration. One system had high concentration of oxygen inthe water and one had low concentration of oxygen. Before the main experiment wasconducted I did a pilot study to test the system setup and included parameters. The result fromthis study and the main study did not show the same result.

It is common today that many children in Sweden  grow up in families that speak two or several languages. Language and identity building is connected to each other. So is also Languages and learning (Becknert m. fl. 2008:13).

The Swedish government have a goal that wind turbines shall produce 30 TWh by the year 2020, compared to about 3,5 TWh produced in Sweden during 2010. To minimize the disturbance that wind turbines create the Swedish Environmental Protection Agency has stated a guideline value that noise from wind turbines at nearby residents shouldn?t exceed 40 dBA, at 8 m/s wind speed. With advanced calculation models, like Nord 2000, the emitted sound from future wind turbines can be calculated at an early stage to optimize the power production without exceeding the 40 dBA. When the turbines have been built there is a need to verify that they really are within the guideline.

The purpose of this thesis was to investigate whether publiclibraries language cafés can support or enable the empowerment of the participants. Empowerment means that the individuals ability to take control of their own lives is strengthened and that the individual becomes more independent. Empowerment also means that the individual takes part in a community. An important part of this is the language. I have developed two research questions: What forms of empowerment can be seen in the respondents' statements? What role do language cafés play for people from other countries, in terms of empowerment? The thesis empirical material consists of interviews whit five people involved in different languages cafes in public libraries in the city of Malmö.

Already in 1988, different levels of participation in the election between different districts of big cities in Sweden were noticed. The problem with low political participation in specific areas has almost always been theoretically explained through an individual perspective. This study is therefore focusing on the problem from a contextual perspective. The hypothesis for the study is as follows, in the case of Malmö the level of participation in elections are affected by social environment in which segregation will be the single highest factor. The dependent variable, participation in the election was tested by the independent variables representing social environment; origin, education, gainfully employed and income.

AbstractIn this master´s thesis I primarily investigate librarians´ and teachers´ conceptions of collaboration between libraries and schools and their conceptions of childrens´reading. Secondary I investigate the contents of laws concerning libraries and schools and also the school curriculums concerning the subject field of the Swedish language. My theoretical point of departure is that of social constructionism. I use two models in my analysis. One is a model of collaboration created by Patricia Montiel-Overall, called TLC (Teacher Librarian Collaboration), which grades collaboration from the lowest level (A) to the highest (D).

This study aims to investigate, describe and discuss the views of a group of adolescents on their identity and the process of second language acquisition. They all came to Sweden and started studying in Swedish schools in the last three years without any knowledge of the Swedish language.The study has been conducted with respect to the adolescents own perspectives and what they consider important.The methods used are group discussions/ interviews, observations in class and informal discussions with teachers and adolescents.Their voices are described and discussed in this paper. One must take into consideration that there is no objective of being neutral or to generalize the results to any other group or category. On the contrary the study has involved critical self- scrutiny and active reflexivity according to ethnographic tradition.Symbolic interaction has provided a theoretical framework for the study. Looking into how social identities may be constructed or communicated from the adolescents voices and looking in to their use of language the study reveals that several expectations and situations need? to be met by different identities.

This report is the result of a case study at Peltor AB during the spring semester of 2007. The task Peltor gave us was to improve the delivery accuracy and to lower the high finical value of delayed orders (backorder), and to divide the products into logical groups. The logical group will be a useful tool to remain a high level of service. If the level of service increases the company will be more competitive.The electronic department at Peltor has problems with delayed orders. According to Peltor, the problem is based on delivery lead time which is presumed.To increase the delivery accuracy, a lead time analysis is made to find the accumulated delivery lead times for each product.

Sweden has a growing proportion of children living in a multilingual environment. It is thus highly important that caretakers as well as professionals who meet these children have knowledge of multilingualism and its impact on language development. Also, an increase of referrals of multilingual children with suspected language impairment to speech and language pathology clinics is seen.The objective of this study was to investigate the linguistic ability in both Swedish and Arabic in a four year old child with suspected language impairment. A further aim was to implement an intensive intervention and evaluate the efficacy of it. Language testing in both languages showed that the boy?s greatest need was in the lexical domain.

The purpose of the study is to examine how teachers and students believe that graphing calculators affect the teaching of high school mathematics courses. By becoming aware of this, teachers and teacher students have the opportunity to reflect on the use of graphing calculators in their teaching. The empirical base consists of interviews with teachers and a survey among students at two high schools in southern Sweden. The results show that teachers especially consider the graphing calculator as a tool, much like paper and pencil. They use it if and when it is deemed able to contribute in a significant way in their teaching, either to save time and/or to help deepen the understanding of various mathematical concepts and methods.

The aim of this essay is to investigate which of the goals in the syllabus, and with that what knowledge of Swedish, four students taking the SFI (Swedish for Immigrants) level 3 course believed themselves to have attained and to compare their self-assessments with their results on the National Test of Swedish for adult immigrants.The method used for the investigation is the individual interview. In addition to taking the National Test, the participants in the investigation were asked to mark the goals they believe themselves to have attained.The results show that the informants who best demonstrated awareness of their own knowledge are able to talk freely about their knowledge and difficulties, and when they mark the goals they believe they have attained, these correspond, on the whole, to how they responded in the interviews.One of the informants finds it more difficult than the others to assess her knowledge. A comparison between her experiences and the National Test results revealed several inconsistencies. For example, she claims that she can communicate in Swedish, but still she didn?t pass the test..

Title: How do you get a pupil from Year 7-9 in secondary school to communicate in German?  Five high school teachers views on how to develop pupils oral communicative skill within the German language The aim of this essay is to explore Swedish secondary school teachers, from Year 7-9 in the German language, opinions regarding which work models and verbal strategies that are used and taught in order to foster the pupils oral communicative skill in the classroom. To achieve this aim, semi-structured interviews with five teachers are used.The results show that the teachers find that they encourage the pupils to speak German through creating possibilities for them to practise their oral language skills. The teachers also emphasize that they believe that alternating assignments in groups or pairs, where the students get the chance to be creative, activates the pupils to speak German the most. They also express an awareness for the fact that open or information questions encourage the pupils to use their creativity and speak more German.
