Energieffektivisering av modern tillbyggnad till äldre skola : fallstudie från Österbyskolan i Österbybruk
The Swedish government has introduced a goal to reduce the energy intensity by 20% to the year 2020. To reach this goal actions need to be taken throughout the energy sector which includes residential and commercial buildings. This thesis considers the possibility to reduce the energy usage in a building located close to Uppsala. The analyzed building is a combined office, cafeteria and entrance and was completed about half a year before this project started. Therefore the measures presented for a more energy efficient building are presented as measures for future constructions.Simulations have been made in VIP-Energy, a dynamic energy calculation program.
Konstruktion av instrument för dragprov på nervceller
This report describes how the system may be exposed to oscillations and how this can lead to resonance. Resonance is a phenomenon that occurs when a system is affected by external periodic oscillations with frequencies close to the system's natural frequencies. Structures subjected to resonance can risk great damage and destruction, why resonance is something that is important to take into account when designing structures. Alternative ways to counteract resonance is to supply damping in the system. Damping means that the resonance decreases instead of letting the amplitude increase.The report discusses some examples on constructions that have experienced the effect of resonance.
En barnomsorg som inte räcker till : En undersökning om hur nattis framställs i media
This is an examination that investigates how daycare during nights, evenings and weekends, so called ?nattis?, is produced in media with restriction to three big Swedish newspapers during 2004-2012. The main intention and the base to this work is to see how media chooses to produce daycare during nights. As a help to find a result to this main intention there are four questions. These questions are which similarities and differences that can be shown in the articles, which main arguments that can be shown, if it?s a positive or negative picture that the articles are producing and which patterns and themes that can be shown. The method to find an answer to these questions and the main intention were an investigation of 21 articles.
Jämförelse av stenull- och polyuretanisolering : Brand- och fuktegenskaper i passivhuskonstruktion
This report compares two different types of insulation with regards to fire and moisture. The materials were tested for the company Fiskarhedenvillan AB, for a wall and a roof construction that the company currently uses in the establishment of Sweden's first certified passive house for international standards.Their current material, Rockwool, is compared to a relatively new material on the Swedish market called SEALECTION Agribalance sold by the company ISO Green AB. The material is a type of polyurethane insulation. This insulation material would result in a more efficient execution of the construction as it provides waterproofing and is applied more easily than Rockwool. From a fire standpoint, literature studies and discussions with fire experts led to results.

Flexibel isolering av fönster för att minska energiförluster
The first part of this essay is about a single-family house that we have planned and projected. Thesecond part is a deeper study in ways to further insulate windows when they are not in use.In the first part the building?s design and its most important construction elements are described.The planning of all major installations (heating, domestic water, ventilation, sanitation, electricity)are reported so that one can in principle start construction of the house. In addition there arecalculations done on the building?s energy management.The result is a two stored house angled toward the south.
Var är min frukost? : En studie av hur elevers övergång till gymnasiet och idrottsinriktad studiegång påverkar elevers frukostvanor
According to the national curriculum guidelines for elementary school, preschool and after-school 2011, (i.e. Lgr11), the Swedish school is based on a democratic foundation. Schools should prepare students to develop an understanding and acceptance of cultural diversity not only in the society as a whole but also how this should be reflected in the morals and ethics between us. The purpose of this study was to describe how teachers in multicultural schools perceptions and experiences on teaching pupils with diverse immigrant origin, and how they apply these cultural expression in practice.In particular, I focus on four teachers in multicultural schools and how they reason about applying cultural expressions that are transmitted at these schools and by them. Explicitly, I review how from policy documents and their own personal pedagogic are reflected in the actual teaching.
Hemlösa ungdomar - ett osynligt problem : En kvalitativ studie om avsaknaden av en enhetlig problembeskrivning
Homeless adolescents are in Sweden rather invisible, as a group. There is no established definition or description of the problem, nor any uniform terms regarding it. The purpose of this study is to investigate how four different organizations, based on their basic principles, describe the group homeless adolescents. We discuss why the organizations reason as they do, and what it leads to. In order to do so we have performed qualitative interviews with representatives from each organization.
Värdet av vinglaset : En studie om hur vinglasets sensoriska och estetiska egenskaper påverkar gästens vinupplevelse
The aim of this study is to examine how preschools contribute to the forming of identity in children, with a specific focus on the quiet and socially withdrawn child. How do the teachers describe the quiet child and the socially withdrawn child? Are there any opportunities for children to be quiet/withdrawn in preschools? These questions have also been analysed from a gender perspective. The method chosen is qualitative method. Nine preschool teachers from two Swedish preschools have been interviewed.
Konstruktioner av kvinnor med utländsk bakgrund : En intersektionell studie av debatten om äldreomsorg och etnicitet i populärvetenskapliga tidskrifter 1995-2008
This paper aims to examine how the construction of women with foreign background is visible in the Swedish debate on elder care and ethnicity. The subject is interesting with regard to the existing discriminating conceptions about ethnicity and how the living conditions of immigrant women are med scarce in the Swedish research field. It is also a relevant topic in light of the incipient crisis of the Swedish eldery care. The examining of how several axes of power interplay to construct the women is rendered possible through an intersectional perspective. This requires of the study to relate to the concept of category, and in this paper I have chosen an intercategorical approach.
Genuskonstruktioner i bilder : Bilder i läroböcker i franska och tyska för högstadiet
ABSTRACT Annie Karlsson Genuskonstruktioner i Bilder Bilder i läroböcker i franska och tyska för högstadiet. Gender Constructions in Pictures Pictures in French and German textsbooks.Antal sidor: 28 Syftet med denna uppsats är att studera hur genus framställs i bildmaterial i läroböcker i franska och tyska för årskurs 7 på gymnasiet. Studien bygger på en kvantitativ samt en kvalitativ analys av hur bilder används och kan tolkas i en franskabok och en tyskabok ur ett genusperspektiv. Resultaten av analysen visar att i båda dessa böcker är bilderna stereotypt orienterade. Flickorna har ljusa eller rosa kläder och bär klänningar eller kjolar för läsaren skall förstå att det är en flicka, och killarna har oftast blå eller mörkt sportiga kläder. Bilderna i boken är ibland vilseledande och matchar inte vad som står i texten till bilden.
?Barnen behöver de att erbjudas mer än bara en sandlåda med hinkar och spadar? : en undersökning kring förskolepedagogers uppfattningar om förskolegården och dess relation till barns lärande
The aim of this study is through a teacher perspective illustrate and analyze how preschool teachers apprehend children´s learning in relation to the preschool yard.The main research questions asked were:How do preschool teachers apprehend the preschool yard in reference to it as a place?In what way do preschool teachers use the preschool yard in their work with the children?How do preschool teachers view the preschool yard and the significance it has on children´s learning?The research is based on data collected through interviews and observations at four different preschools in the same municipality. The research views place and people as social constructions, a theory of knowledge that is based on the view that the world, places and people are constructed in relation to each other. This perspective as well as previous research is used for analyzing the data collected through a qualitive study based on interviews. The data analyzed show that the preschool teachers involved in this research apprehend the preschool yard as a central part in the learning of young children.

Fuktskador i bostadskök : En undersökning om fuktskador i kök och hur dessa kan förebyggas vid nyproduktion
Moisture damage in kitchens is an area that many people believe to be irrelevant andnot a subject to concern, however the problems encountered might be larger thananticipated.The purpose of this essay is to get a view of how problematic moisture damagecurrently is as well as what can be done to prevent damage during the constructionand building of new housing.Statistics regarding moisture damage as well as several tools for damage preventionhave been studied and investigated. Industrial regulations have been reviewed tounderstand the requirements construction companies must legally follow during theconstruction and building of new kitchens. Home manufacturers and largerentrepreneurs have been contacted in order to get their point of view regarding theproblems with moisture damages in kitchens.The knowledge of moisture safe constructions is prevalent by home manufacturers,insurance companies and entrepreneurs. Despite this knowledge, the constructioncompanies predominately follow the industries regulations, which normally onlyimplement the minimum requirements.In order to get construction companies to design and build kitchens with increasedmoisture security, stricter industrial regulations might be needed to be implemented.Unlike bathrooms and laundry rooms, kitchens are not defined as a ?wet room? andthe regulations for the construction of kitchens are more lenient.It is difficult to detect water leaks in an early state and the moisture damage is usuallyextensive before it is discovered and repaired if the kitchen lacks moisture securedconstruction and water security.
Utvärdering av styvhetsegenskaper hos ett nyutvecklat träbjälklag av limmade sidobräder
Idag blir det allt vanligare med träbyggnader högre än två våningar. Detta tillsammans med en modern arkitektur som ger stora öppna planlösningar ställer höga krav på bjälklagen i träbyggnader. Problematiken med långa spännvidder för bjälklag i trä är att klara kraven för svikt och nedböjning. Dessa krav måste uppfyllas för att säkerställa funktioner hos andra byggdelar och för att människor inte ska uppleva att golvet sviktar eller vibrerar på ett obehagligt sätt.Ett träbjälklag bestående av limmade balkar av sidobräder har utvecklats. Bjälklaget är utformat av balkar med I-tvärsnitt i primärriktningen och rektangulära balktvärsnitt i sekundärriktningen.
