AbstractIn urban societies people spend more and more time indoors, which put great demands on the indoor environment. If the ventilation is to manage the removal of unwanted substances in the indoor air, a good mixing of the air is required. The question arises that, whether the buoyancy forces will counteract a good mixing of the indoor air or not?This report aims to clear up the difficulties whether you need to consider the buoyancy forces or not, when adjusting a ventilation unit. For studying the indoor mixing of the air a two dimensional model is constructed in COMSOL Multiphysics.

In my work as speech and language pathologist I often meet people emerging from coma andtheir experiences intrigue me. Coma is an eluding human condition that offers a challenge formodern science and our view on body and mind. In my Master project in Creative Writing Iwanted to try to enter this zone that is so hard for a clinician to reach: the personal experienceof being in a coma. By writing HUSK MIDAS I have tried to create a realistic fiction based onresearch on coma state and real-life stories of people waking up from coma.In my exploration of the coma state I found that lucid dreaming is common apart fromdreaming, many patients experience sensory inputs like sound and touch which aremisinterpreted and woven into dreams and creating a feeling of confusion and fear.Coma is a frequent theme in literature and film but is often depicted unrealistically andmisleadingly. A few works like Artur Lundkvist?s Journeys in Dream and Imagination andthe film The Descendents by Alexander Payne show a more reality based fiction.

Syftet med studien är att undersöka hur lärare i årskurs 1 respektive 3 beskriver och motiverar sitt arbete med språkutveckling och läsförståelse tillsammans med högläsning. Studien utgår från följande frågeställningar:Hur beskriver och motiverar lärare sitt arbete med högläsning?Vilka arbetssätt används för att förstärka högläsningens effekt på elevernas språkutveckling?Hur arbetar lärare så att elevernas läsförståelse gynnas tillsammans med högläsningen?Skiljer sig det aktiva arbetet med högläsning åt mellan årskurs 1 och årskurs 3 i just de här skolorna? I så fall hur?Studien gjordes med hjälp av en enkät som har besvarats av 50 lärare och intervjuer med fem lärare som arbetar i årskurs 1 och årskurs 3. Studien utgår fyra teorianknytningar och dessa är Lev Vygotskijs teori om sociokulturellt perspektiv, Vygotskijs teori "Zone of proximal development", Aidan Chambers teori om boksamtal och Barbro Westlunds teori om lässtrategier. Resultatet av studien visar att lärarna beskriver högläsning som ett positiv arbetssätt som utvecklar elevernas språkkunskaper och läsförståelse.

During the summer of 2007 I was employed by Högestad Christinehofs Förvaltning AB. My main task was to make an inventory of giant trees at the estate. Högestad and Christinehof,which with their total possession of 13 000 ha of land is the biggest estate in Scania. A giant tree is a tree with a diameter in breast height more then 1 meter. Trees of these dimensions are registered by Swedish authorities. Landowners with a giant tree on their property can receive a subsidy for cutting trees that are in competition with the giant tree.(Levenskog, 2007) Giant trees are important for biodiversity in the landscape and there are important habitats for different insects, birds, bats, lichens and funguses.

Denna studie är en fallstudie vid två av Magelungens dagverksamheter. Studien inkluderar tre olika perspektiv: ungdom, förälder och behandlare. Syftet med studien har varit att undersöka informanternas upplevelser av ungdomens tid på Magelungens dagverksamhet. Detta har gjorts genom en kvalitativ metod där sekundärdata, i form av nio intervjuer genomförda av Magelungens forskningsgrupp, har bearbetats och analyserats genom meningskoncentrering. Studien tar avstamp i den kunskapslucka kring kvalitativ forskning om dagverksamheter som forskningsgenomgången visar på.Resultatet tyder på att informanterna generellt sett är nöjda med tiden på dagverksamheten.

The study seeks to from professionals perspectives describe and analyze the beliefs they have about women with intellectual disabilities and their pregnancy and motherhood. We will also discuss and reflect on the possible support that professionals find important for women to handle pregnancy and motherhood. The information has been gathered through interviews with five different professions that have come in contact with the audience in their work. In our material we found three distinctive perspectives: a child´s perspective, a parent´s perspective and a community perspective. From these perspectives, we could find many similarities in the informants´ perceptions, which resulted in different themes.

The purpose of this study is to describe some primary school teachers understanding of language development and approach of first and second language speakers with Arne Tragetons Writing to reading, for pupils in early ages.By using a qualitative method with interviews and participant observations and informal conversations, the basis for the survey was collected. Four teachers in three schools participated. The proportion of second-language pupils at each school was 35%, 17% and 0%. My theoretical starting point in the study was the hermeneutic research tradition, which has been used to interpret and understand the collected material. Theories of behaviorism, constructivism and socio-cultural perspective has been used in the analysis part of this study.

 This study aims to deepen the understanding of which opinions and perceptions the teachers in the study have about the national goals, as well as local, when they plan their lessons in science studies for the younger ages. We wish to illustrate which goals these teachers find most important, their opinions on how they use these and how the different goals affect their design of teaching. The study also aims to examine which syllabuses, national or local, the teachers believe have an effect on their planning. Data were collected by interviews with four teachers, combined with questionnaires sent to 25 teachers teaching in science studies in forms 1-6. To analyse the data, key terms from Vygotsky and a sociocultural theory was used, such as situated learning, artifacts, the zone of proximal development, thinking in group and mediation. The data was also interpreted and examined by recent studies regarding this subject. The results show that the teachers find their own knowledge, the national syllabus and their colleagues as most important for their planning.

The purpose of this enquiry was to study how the rhetoric about immigrants (invandrarprat) influences the interpretation of reality in regards to new swedes. The study was conducted with the help of qualitative interviews with eight new swedes who, apart from their country of origin, by Swedish social standards would be considered average. Two questions were examined for the purpose of this study:1. How do new swedes react to rhetoric about immigrants?2.

The purpose of this study is to investigate how twelve middle school teachers use educational tools and what influences their choice of educational tools in Swedish language writing instruction. To answer this purpose, three research questions were formulated: What does writing instruction look like for middle school students according to the teachers in the study? What influences teachers' choice and use of educational tools in writing instruction? What opportunities and challenges do teachers experience in Swedish language writing instruction when using different educational tools? Twelve teachers from variously sized municipalities and with different experiences participated in the study through purposive sampling and convenience sampling. The chosen method is qualitative semi-structured teacher interviews. To analyse the results, this study employs analytical tools from the sociocultural perspective, using concepts such as mediation, appropriation, the zone of proximal development, and scaffolding. The results show that both analogue and digital tools are used in the teachers' writing instruction. The choice of tools should be based on pedagogical considerations, with an emphasis on social interaction and collaboration during the learning process.

Purpose: The purpose of this study is to examine different organizations' views on their communicative crisis work. The study will analyze organizations' crisis prevention efforts, its views on the crisis of accountability in relation to stakeholders and to work for a crisis to be elucidated. In order to delineate the study focuses the investigation on various train organizations. Then the concept of crisis is something that circulated widely in the train sector in recent years.Theory: This examination has chosen to use the theory Situational Crisis Communication Theory. It is an empirically tested theory of a collection of different strategies.

The present study deals with the scope of action available to a social worker when analyzing, assessing and proposing measures regarding young persons experiencing social problems. The interest in the subject area emanates from the fact that the number of youth placed in different forms of round the clock out-of-home care in Sweden increases, whereas research in the subject shows that such placement gives few positive results and sometimes even has negative consequences for their development.The study investigates how the preconditions of the social worker influence their scope of possible action, in particular as regards their place of work, the situation of the individual dealt with, and the profession itself being one based both on scientific evidence and knowledge gained by experience. Lipsky?s theory on ?street-level bureaucracy? and Hasenfelds theory on human servicing organizations form the theoretical framework of the present study. The empirical input comes from interviews with focus groups of active social workers.The analysis of the interviews shows that social workers generally feel that they have a broad scope of action as far as the regulatory framework and office management are concerned.

The stretch from the riparian zone of a major river, through the mouth and upstream in tributaries forms a range of differing habitats. The aim of this study was to investigate the effect of these different habitats on the riparian frog community in primary rain forest in Borneo; i.e. examine whether any gradients could be demonstrated in terms of species composition, diversity and density of frogs, as well as which environmental characteristics that seem to be of most importance in forming habitats of high conservational value. A major river, Segama, and three of its tributaries were investigated. The surveys were carried out at night by searching for frogs visually and acoustically along the streams, from the shore of the Segama river and 400 metres upstream in the tributaries.

I dagens läge har energifrågorna väckt ett stort intresse i samhället. Nu fokuseras det mer på att bygga energisnålare hus. En betydande faktor som påverkar energiförbrukningen i våra hus är köldbryggor. De uppstår då ett material med dålig värmeisolering bryter igenom ett material med bättre värmeisolering. Köldbryggor är nästan omöjligt att undvika, dock går alltid att reducera.

The purpose of this study has been to analyze how managers within the elderly care who operate according to the Social Services Act work to support the assistant nurses with the social documentation. In order to achieve my purpose and to be able to answer the research questions, a qualitative approach was selected. My empirical material consists of seven interviews, four with assistant nurses and three with managers. Anthony Giddens? structuration theory in Månsson, (2003 s. 422) has been my theoretical starting-point and the concepts of practical and discursive consciousness have been used in the analysis.
