In the fluidized bed furnace at Rönnskärsverken, Skelleftehamn, sulphur-containing ore concentrates are roasted in order to remove about 50% of the sulphur in the incoming ore concentrate. This occurs in order to reach the goal of a matte containing 55% of copper in the following smelting process. At the same time as the ore concentrate is partially roasted pollutions as arsenic, antimony and bismuth are expelled. Earlier made thermodynamic calculations of equilibrium suggested that calcium and magnesium form stable compounds with arsenic and thereby inhibit expellation of arsenic in the fluidized bed furnace, an element that is undesired. The purpose of this thesis work was to gain knowledge of the mechanisms behind the formation of these stable arsenic compounds.

Projektets syfte var att undersöka om en handdator kan stödja distriktssköterskans arbete. I rapporten beskrivs hur vi tillsammans med distriktssköterskor har iakttagit i vilka situationer handdatorn kan vara ett hjälpmedel. Om patientjournalen är tillgänglig via handdatorn vid hembesök skulle det styrka de av oss utvalda nyckelorden som representerar distriktssköterskans yrkeskunnande; "seende", lyhördhet, kommunikation, flexibilitet, prioritering, beslutsfattande, dokumentation, framförhållning samt utveckla ett minne och självständighet. I rapporten skriver vi också om hur distriktssköterskorna tillsammans med oss har påverkat utvecklingen av det grafiska gränssnittet i designprocessen. Vi visar med mock-upbilder hur denna process har framskridit och vi pekar på hur viktig användarmedverkan är.

Contemporary plant design can be examined by how it relates to two extremes - Nature and Art. This idea is explained by Noel Kingsbury in the book The Dynamic Landscape where he places designers and their projects on a gradient (Kingsbury, 2004). Nature, one of the extremes can be represented by a dynamic, species-rich plant design with native species and with nature as the ideal. The other extreme - Art implies a more static view on plant design. Here, the designs consist of colourful flowers, exotic species and cultivars with double flowers.

Through qualitative interviews with six teachers at a school an understanding of teachers´ conceptions of, and conditions for their work on pupil democracy and student participation are sought.Formulation of questions were as follow:What does pupil democracy and pupil influence mean for selected teachers?How do selected teachers´ work with pupil democracy and pupil influence?What opportunities and complicatedness?s do selected teachers see with this work?Through this the selected teachers views on children and their thoughts on their role as a leader also are investigated.According to the curriculum the Swedish school should aim to transmit primary democratic values and pursue the education through democratic work models. Further the pupil should acquire influence of their education. The theory exposes several approaches on democracy and influence. These approaches are further on applied on the school.The result of the study evinces that selected teachers´ practice both pupil democracy and pupil influence.

The aim of this Masters thesis is to examine what part and importance electronic games play in the life of girls, how the girls use electronic games and what the girls think and say about their use of electronic games. We also intend to examine what girls have to say about electronic games at the public library. Our attempt is to illuminate and bring knowledge to those who work within the library with the selection, purchase and conveyance of electronic games. Method used in the survey is focusgroup-interviews with girls in the age between 12-14 years in three different schools. The findings are related to four different perspectives, theory of child development, from a gender perspective, theories of understanding how young people use computer games and theories to understand the purpose of public libraries.

Användandet av trådlösa nätverk ökar med rask takt och blir allt vanligare. Enligt en artikel i Computer Sweden kommer de trådlösa näten att ha 20 miljoner användare om 4 år. Analysföretaget Gartner Group har nyligen gjort en undersökning bland företag, vars syfte var att ta reda på hur stort intresset var för WLAN. Resultatet visade att 50% av företagen funderar på att köpa och installera WLAN-lösningar (Planet Wireless september 2001). Syftet med detta arbete var att beskriva hur den inbyggda krypteringsfunktionen WEP som för Wired Equivalent Privacy fungerar och hur säker den är, dvs hur lätt man kan knäcka krypteringen. Följande frågeställningar har besvarats genom litteraturstudier och ett praktiskt försök: Hur är trådlösa nät uppbyggda? Hur fungerar den inbyggda krypteringen WEP och hur säker är den? Vad kan man göra förutom att använda sig av WEP för att skydda sig mot avlyssning/intrång? Det praktiska försöket bestod av att knäcka WEP-krypterade filer med hjälp av programmet WEPCrack.

Aim: The aim of the study is to show how a Bildung-oriented biology teaching could be designed, along with providing classroom examples of such teaching. In this study, the term Bildung, is defined based on the German Didaktik tradition as competences for self-determination, constructive participation in society, and solidarity. Theory: The study is based om Englund?s thoughts of teaching as didactic choices that express different views of meaning, socialisation, method, and context. This is referred to as companion meanings. Additionally, the theoretical framework is influenced by Gadamer?s thoughts on understanding through dialogue and Klafki?s didactic analysis of educational content for Bildung-orientated approaches. Method: The empirical qualitative study is based on ten semi-structured interviews of biology teachers at Swedish Folkh?gskola.

The ever-changing modern health care environment places high demands on leadership skills. The purpose of this study was to describe the causes that effect leadership within the health care services carried out in a municipality. Data was collected by interviewing four health care managers, three registered nurses, eight enrolled nurses and one auxiliary nurse. A qualitative approach based on a content analysis method was conducted in the analysis of the interviews. Latent content deals with relationship aspects and interpretation of deeper underlying meaning of text.

In each classroom there is a teacher with good intentions wanting what´s best for their pupils. But grades and tests in mathematics from 2009 in Sweden shows there is a crack between the subject being taught and the learning child. The purpose with this research is to find an understanding from a teaching and learning perspective of which teaching method is more suitable for teaching and learning mathematics by doing a comparison between two methods. The main question is:What are the advantages and disadvantages of the traditional and the laboratory method of teaching, supported by the two keywords teaching method and learning?This C-paper is based on a qualitative research aiming to gather an in-depth understanding of human behavior.

The data was collected primarily through semi-­?structured interviews.Research findings: Through the study?s interviews and their results is it possible to see that staffing companies in Växjö is working with trust.

This master's thesis sets out to explore information literacy in a contextualized learning environment with emphasis on students at a vocationally oriented program in the Swedish upper secondary school. The concept of information literacy is widely discussed and furthermore a common subject for research within the field of Library and Information Science. Information literacy can be described as a set of skills or a range of attributes defining an information literate person. The skills and/or attributes facilitating the development of critical thinking and problem-solving skills are often linked to knowledge about computers and libraries.Another view on the concept of information literacy has been developed by the Australian researcher Annemaree Lloyd. She stresses the importance of social and physical information sources and that these also should be included in the development of information literacy.
