Överkänslighet mot kemiska ämnen i vår omgivning skapar hälsoproblem som ?sick building syndrome? samt ?multiple chemical sensitivity?. Båda tros kunna starta efter långvarig lågdos-exponering av kemikalier som till slut resulterar i en överkänslighet. Symptombilden är blandad och diagnostiseringen svår. Bland annat stress verkar vara en påverkande faktor liksom det kemestetiska hudsinnet.

A common way to stabilize high rise buildings is to use an elevator core built of concrete. Today, we use to build these elevator cores of in-situ concrete. Precast concrete twin wall (double wall) is a semi-finished product that has become more common in recent years. This diploma work studies how the twin wall works out as structural elements in an elevator core. The work also shows some possible ways of designing twin walls and highlights some important parts of the design that will be vital to the stability of the building.    The result shows that it is important to think through where the element joints should be placed.

This diploma work has been conducted for the consulting company Ramböll inUppsala, Sweden with the purpose to perform a study with the calculation programFEM Design 9.0 made by Strusoft. The aim has been to find out if it is possible to gainadvantage by utilizing more advanced 3D software for design calculations, instead ofthe traditional methods currently used in construction works.The method of approach has been to model an existing warehouse building with theprogram FEM Design, and then compare the results with those attained with FrameAnalysis and hand calculations. These results are then analyzed. An evaluation is maderegarding to what benefits can be achieved using a more advanced 3D-model.The results of the study show that the differences between the methods are not ofany significance with regard to the design of the steel frame. However in morecomplex materials such as reinforced concrete, the differences become more notable.The conclusions drawn by the authors of this study into FEM Design are that theeducation requirements of the program are higher than for simpler programs, whosepurpose are solving predetermined problems.

The purpose of this study is to examine whether religious behavior or religious identity changes when a person with Muslim background moves to a Christian country and also very secular such as Sweden. I have interviewed five people with Muslim background that have moved from Turkey to Sweden. In this study I have applied Anthony Giddens and Thomas Ziehe's theories about building up an identity but also Nader Ahmadis theory of migration and identity.The results of this study show that there is a change in the practice of religion but also that this differs between these five people who came from the same country. Nevertheless, a change in the practice of religion can on one hand be as a result of modernity and on the other hand, exclusion of family. It also proves that it is not possible to draw general conclusions on this issue instead it should be looked at from an individual perspective..

The Swedish real estate market has experienced an intense increase of demand during the last ten years. Thus, people regularly visit real estate websites, as well as home improvement and interior design have become extremely popular. However, the Swedish real estate agencies still have not developed a theoretical framework on how to most effectively market the properties. The main purpose of this study was to investigate how interior in apartment advertising affects the buyer's interest in the apartment, and furthermore to start building a framework for how to effectively use interior as a marketing tool. The study connects theory regarding social identity, advertising effectiveness and product personality in order to investigate consumer behaviour in the real estate market.

The purpose of this study was to find out whether young women´s conceptions on femininity are based on school culture or other possible factors. The theory chosen for this study is the sociological perspective. A theory where sociologists such as Emile Drukheim, Talcott Parsons and Pierre Bourdieu are all prominent. The discussion links to Habitus and their theories on social, cultural and collective groups. A qualitative method has been used.

Denna studie har utförts med avseende på förvaltning av byggnader enligt BREEAM In-Use, som används för miljöcertifiering av befintliga byggnader. Rapporten är inriktad på aspekterna av att certifiera en byggnads förvaltning samt den verksamhet som förs inom denna. Kopplingen mellan brukaren och förvaltaren är väsentlig för att säkerställa att man uppnår de krav som BREEAM ställer. Ett hjälpmedel för att främja denna kommunikation mellan dessa parter är de gröna hyresavtal från fastighetsägarna, som har visat sig vara en nödvändig länk. Det har visat sig att befintlig förvaltningsmetodik behöver utvidgas i dess rutiner och att kunskap om BREEAM är nödvändig inom förvaltningen.

The purpose of this study is to explore how preschool teachers succeed in their mission to conduct work that will enhance children's interest and knowledge in technology. The study was conducted by qualitative semi-structured interviews among eight teachers at seven preschools in the same municipality. The method was chosen because I wanted to get as detailed and full answers as possible. I also wanted to find out their individual perceptions. The result shows that most of the teachers think that they have insufficient knowledge to practically work with technology. At the same time they?re expressing that technology is a broad area that sometimes is a little more complicated than it needs to be.

Sustainability and the traffics impact on the environment have become increasingly central within spatial planning. For many years, planning has been focusing on building new roads - this has resulted in increased use of automobiles, which many believe is unsustainable in the longer term. Therefore, authorities at national, regional and local level want to increase the use of alternative transport modes ? such as walking, cycling and traveling by bus.The thesis intends to study if the Municipality of Umeå?s policies for sustainable development have led to an increased use of public transportation. The use of public transport in Umeå is also compared with developments at national level, in order to see if there are differences in the level and trend.

This report describes the building of a computer model that makes it possible to simulate the thermal climate in a greenhouse. The computer model is built on the physical theory of heat exchange that occur in a greenhouse, such as radiation and convective heat exchange. The model also includes the heat storage that is active in a greenhouse.The computer model is used to simulate the thermal climate in a greenhouse under three periods, winter, spring and summer. It also investigates which effect a concrete wall has on the thermal climate in a greenhouse. The purpose of putting a concrete wall in the greenhouse model is to investigate the possibility to store heat during the day and then use this heat when the temperature drops during the night.The result from the simulations shows that a concrete wall levels the big difference in temperature that normally occurs under a day in a greenhouse.

Urban planning in Sweden goes back to a prolonged tradition, and even since the beginning of the 16th century there´s been general plans for urban planning for cities in Sweden.Nowadays every municipality has a directive from the government to establish or re-new the general master plan covering the whole municipality every 4th year.The aim of this paper is to illustrate and shed light on the extent for the planning document and guidelines, and how they change from every active period and in what extent the provisional planning reaches its visions regarding the outcome of the actual city growth. This study was completed by studying the position of every apartment building that?s been constructed for the chosen area over the years of 2000 - 2014 and draw comparisons between the current master plan main visions regarding constructions ? and comparing the two separate visions to pin out the differences in the same subject.The result shows that there are some deviations from the plans but not as much as one would have thought in the city growth, and some deviations from the different planning documents. Some of the deviations was greater than others but overall the visions was about the same..

The purpose of this study is to highlight play and learning in the lower school ages in organized and non-organized break actives. The premise is that the break is a part of the schoolday and that the school has responsibility to live up to the goals and guidelines of the curriculum even in recess. Leisuretime-pedagogy and the professional competence the pedagogs possess about games and the social relations of children are also in focus in this study. The study is a qualitative study where the empirical material consists of observations in a schoolyard environment during one week and interviews with children. The material has then been interpreted and analyzed using Lev S.

Efficient energy use in the housing sector is crucial for achieving a sustainable society. The expansion of this sector only represents a fraction of the existing houses, hence it?s within the existing houses the potential for energy savings lie. This potential has been analyzed in order to determine if it?s possible to cut the current energy demand in half.

En Urban Allmänning på Hornsbruksgatan. Kombinationshus med bostäder, T-bana och kontor .Sträcker sig över en 150 m lång slits på gatan.Uppdelad programmatskt med kommers i BV och bostäder ställda ovanpå som fria punkthus.Taket till kommersdelen/sockelvåningen ger tillbaka en park till stadsrummet. Det är den som är den urbana allmänningen.Byggnaden behandlar en höjdskillnad på c:a 6 meter från början av sockelvåningen till slutet. Därför varierar byggnaden i takhöjd vilket ger olika rumsligheter och skillnader i program som anpassats efter de olika höjderna. T.ex ett öppet andra våningsplan i västra delen som bidrar till dubbelt antal kontorplatser i frilanskontoret.Frågor jag ställt mig under processen var: Vad är en bostad idag? Vad är ett kontor idag? Vad kommer Hornstull att vara i framtiden med sin nya galleria? Vilka bostadstypologier råder i området?Dessa frgor har jag tagit i beaktande under förfarandet och kommit fram till en boendeform med yteffektiva och ljusgenerösa lägenheter i funkistyp.
