Allergifritt boende genom val av invändiga ytmaterial

The number of people of getting allergic symptoms is increasing and the reasons are considered to be many. The human have changed their habits and spend more time indoor. In combination with new building technologies where denser housing constructions and new materials this causes bad indoor climate contributes to a higher occurrence of allergiesThere are several courses of action to deal with this problem. One action is by choosing allergy-free interior surface materials. An allergy-free material emits low concentrations of harmful substances resulting in a great indoor air quality.

Konstruktion av efterbehandlare

The purpose of this report is to examine various roof structures that can operate in a warehouse with large spans. The building that is examined in the report is currently under construction, and the roof construction has already been selected. The selected roof system will therefore be compared with some other structures and materials that have been possible. The report will evaluate three different frame materials, two insulating barriers and two overlaying materials. Another important part in major construction projects is the roof safety.

Bildernas byggstenar : En studie om pixlar och vektorers egenskaper i form av digitala material

With a new digital world that runs parallel with our physical one, we are also facing a new type of architecture and new materials that this new architecture is built on. In this thesis I examine pixels and vectors, two of the digital materials used to create pictures. By approaching them as digital materials, I have mapped their different qualities, when and where one or the other is more or less applicable and the reason behind it. My main research question asked was the following: Are the (digital) materials challenged outside their primary fields of application, and in that case, in which way? With this question in mind, I carried out a semiotic picture analysis on four pictures, later on dividing them into four different categories, based on their different qualities and their ability to deliver information.

Produktutveckling av flytbarhetsutrustning

Detta examensarbete omfattar produktutvecklingen av en komponent till en mätutrustning som ska mäta flytbarheten hos smält metall.

Arbetet har även utvärderat ett för gjuteribranschen nytt formmaterial som alternativ till dagens gjutsand. Tester har gjorts för att se om återvunnet (material x) går att använda som formmaterial till högtemperaturapplikationer..

Landet lagom och dess "lagomläromedel" : Om jämställdhet och genus i grundskolans läroplaner och läromedel från olika årtionden

The purpose of this study is to examine two educational materials from different decades, to see if they have a conscious gender and equality perspective, and to see if they have followed the development society made regarding gender and equality. Even the curricula have a part in my study as I will relate them to the educational materials. Equality as a concept means briefly that women and men should have the same conditions, and gender depicts our notions of femininity and masculinity.I have chosen to do textual analyses, focusing on multimodal discourse because I analyze both text and image. I also use both quantitative and qualitative methods.My questions are: In which way do the curricula and the educational materials express equality?; In which way do the curricula and the educational materials express gender?; Do the educational materials express the fundamental values written about equality and gender in the curricula? And, if this is the case, does it mean that educational materials have followed the development of the Swedish society?The conclusion of this work is that equality and gender are presented as goals in both curricula, but the new curricula have developed that section more.

Religion och vetenskap : En studie om tematiken religion och vetenskap samt dess gränsländer i gymnasieläromedel

The following essay aims to determine what textbooks and teaching media educators in the county of Västerbotten use when teaching the relation between religion and science. Based on educational science theory and through analyzes of factual texts, the teaching materials was examined to determine how much focus they put on the thematic of religion and science. The result shows how the different teaching materials affect this thematic differently. The main conclusion is therefore that students in Sweden could, depending on the teaching materials used in their education, be taught by different standards to reach the same requirements..

Teknik i förskolan : En studie om hur 4 - 5 åringars uppfattningar om material och dess egenskaper kan utvecklas genom en pedagogisk aktivitet

The purpose of this work is to investigate how 4-5 year olds perceptions of materials and material properties can be developed through an educational activity. The study is based on two interviews with eight children in that age category. The interviews were conducted before and after an activity where the children were first introduced to the subject by the tale of The three little pigs (Harris, 2009) and then given the opportunity to explore various materials related to the book. The kids got to experiment and explore how water affected materials and to compare different materials properties. The children were also attracted to build and create the material that was offered during the activity.

Matematiska arbetsmetoder : En kvalitativ undersökning om undervisningsmetoder i förhållande till nationella matematikprov

The categories I will use are outdoor education, textbooks, learning materials and problem solving. Laboratory materials can be everyday materials and educational materials in which pupils have an abstract understanding of the subject. This survey was conducted through interviews and observations. The survey was also conducted in relation to student performance in national math tests.

Barns pedagogiska material : En kvalitativ studie om barns användning av det pedagogiska materialet som finns på fem förskolor och om sex pedagogers tankar kring placeringen av det pedagogiska materialet

?Childs pedagogic material ? A qualitative study of child?s use of pedagogic materials available at five nursery schools and about their teachers thoughts about the display of the pedagogic material?In the nursery preschool the environment and the educational materials have always had a central place. That's why it has been chosen to study and observe five preschools and interview sex teachers, in an attempt to understand the teachers thought about the choice of material and the choices of material that the children used. The reason I do this is to see what the underlying idea about the materials the children use is, and why educators choose to make certain materials visible. The purpose of this study is to examine the educational materials that are used to stimulate children´s learning and examine what determines the choice of educational materials.

Demokratiteoretisk analys av läromedel i Samhällskunskap : En kvalitativ studie om det demokratiteoretiska innehållet i läromedel för Samhällskunskap 1a1 och 1b under GY-2011

This qualitative study is done with the purpose of creating understanding for the theoretical democratic content in educational materials for Civic Education courses 1a1 and 1b during GY-11, so teachers create an intentional approach when using educational materials in their democratic education. This was motivated as important considering the reduction in obligatory Civic Education for the vocational programs. The study was conducted using a hermeneutic qualitative reading method where the educational materials, more specifically two series with one book for each course, was read with purpose of creating understanding for the democratic content according to ideal democratic models: deliberative democracy, participatory democracy and electoral democracy. A text voice analysis was also conducted using Bakhtins theory of dialogic and monologue text that contributed to the general result concerning the democratic content. The results show that the electoral democracy ideal is dominant in all educational materials, there is hence no striking difference between the democratic content in 1a1 and 1b educational materials.

Mer är bättre än mindre - En fyrdimensionell undersökning om kampanjmaterials påverkan på butiksmiljön

The purpose of this study is to investigate the effect of using more promotion material to enhance the in-store communication of sales promotion. In the retail industry today the research regarding the benefits from using various in-store promotion materials is limited, thus this study was carried out to bring clarity to this subject. The study is carried out in two pharmacies and the design of the study was to add more promotion materials to one store, while keeping the other store in its normal condition and then let the stores change conditions after one week e.g. latin-square design. The data collection of this study consists of four different methods: sales data, a questionnaire with 182 customers, an observation study of 300 consumers and an eye-tracking experiment with 41 participants.

Val av samarbetspartner vid bildande av strategiska allianser för små och medelstora teknikföretag

Background: A majority of strategic alliances do not create value for the participants. One of the main reasons for the high failure rate is an inadequate process for partner selection. If the correct partner is not selected, it can have serious effects on the management of the partnership. This is a serious problem since failed alliances usually are very expensive for the involved companies. Purpose: The purpose of this thesis is to investigate which theoretical factors are important when selecting a partner for a strategic alliance.

Det meningsskapande materialet : platsidentitet och materialitet i vår byggda omgivning

The physical environment is constructed of materials. The materiality of different places contributes to how places can be distinguished and the material can contribute to the construction of place identity. For architects with different orientations the material is one of the principal means by which they can express their idea. The material remains when the design process is finished and instead the material becomes a precondition for how people will perceive and deal with the place. The literature study of the essay examines how the concept of place and materiality is dealt with in different disciplines and how these descriptions are linked to the concept of place identity.
