Inverkan av fukthärdning och relativ fuktighet på sprutbetongens krympning

Efterbehandling på sprutbetongen skall enligt regelverk som BV-tunnel och Tunnel 2004 ske direkt efter sprutning. Fukthärdning av sprutbetongen behöver tillämpas då den relativa luftfuktigheten understiger 90 % vid betongytan. Fukthärdning skall då utföras så att betongytan ständigt är fuktig, under hela härdningsperioden fram tills att betongen har fått tillräcklig hållfasthet. Då cementet hydratiseras bildas olika kristaller som ger cementmaterialet dess hårdhet och hållfasthet. Med krympning menas här rörelser i betongen som orsakas av vattenavgång i form av avdunstning från betongen och genom kemiska reaktioner i hydratationsprocessen. Syftet med denna rapport har varit att studera effekten av varierande fukthärdning på sprutbetongen.

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.

Undervisning och dyslexi : Några gymnasieläraren arbetssätt för att stödja elever med dyslexi

According to the curriculum the teachers have a responsibility to adjust the activities in the classroom in order to suit the pupils and to give them the means of assistance the pupils need to be successful in their learning. The teachers should also stimulate the interest to learn and support the pupils? self esteem. One of the problems a dyslectic pupil faces is an often weak self esteem. Another is the weak phonological awareness which makes it hard to fully understand the context and to recognize different phonemes when writing.

Concrete - en mönsterkollektion för modetextilier

Mitt examensarbete består av en mönsterkollektion för modetextilier. Kollektionen består av sex mönster där jag har använt digitaltryck och laserskärning på olika typer av siden. Jag har hämtat inspiration till kollektionen från mina intryck av London där jag vistades i fyra månader under hösten 2011. Med London som utgångspunkt har jag samlat bilder för att hitta en stämning att arbeta med. Utifrån bilderna valde jag tre ledord att basera min skissprocess på, dvs.

Yrkesidentitet och yrkeskultur i det Arbetsplatsförlagda lärandet : en intervjustudie med sex handledare för elever på Barn- och fritidsprogrammet.

The purpose of this examination was to find how supervisors interpreted the termsvocational identity and vocational culture, found in the diploma goals in workplace-based learning at the Child- and Recreation Programme. To reach the purpose, I formulated questions that I answered through a qualitative study. I made six interviews with pre-school teachers who had been supervisors for students at the Child- and Recreation Programme. The informants answered the same questions and the answers were recorded. The result of the study showed that the supervisors made a fairly consistent interpretation of the terms.

Skolbiblioteket och progressionen inom grundskolans användarundervisning

The purpose of this essay is to examine progression in user education atprimary and secondary school levels, specifically the role played byschool libraries, librarians and strategy documents in securingeducational progression. Progression is examined in the user educationprovided by the five schools, part of the same municipal schoolmanagement area which share the same strategy plan. The area, NorraFäladen, was awarded School Library of the Year in 2011 for its work,making it particularly interesting for this essay's purpose. The studycombines interviews with the area's three school librarians, who dividetheir time between the five schools, with an analysis of the strategydocuments that regulate user education within Norra Fäladen. Theanalytical framework is based on: AASL's model of progression in usereducation (Standards for the 21st-century learner); Ekström's model forsuccessful and active strategy documents; Kuhlthau's theory of thelibrarian's role in the information search process; and Limberg'staxonomy of the role of the school library.The study shows how a number of concurrent factors and prerequisitesinfluence how goals for progression in user education are met.

Modersmålsstöd i förskola : En intervjustudie om modersmålsstöd på tre förskoleavdelningar i ett mångkulturellt område

The purpose of this study was to broaden knowledge about how native language support works in three pre-schools departments in a multicultural area. The questions were how native support works in the current pre-schools departments, which language development methods and forms used by educators to work with native language support, and if they experience any difficulties. I used interviews as a research method, with three child-care and one preschool teacher.The results showed that all departments on both of the pre-schools have native language support with a permanent bilingual staff, outside the ordinary activity. The mother tongue is also spoken in the everyday activities in two of the departments. The third department is only spoken native language with their children if they do not understand what they say in Swedish, or if they are sad.The concrete material is lifted up as a good and important tool in all three language groups, because verbal language is not always enough for all children to understand.

Badhus

Ett nytt badhus i Västertorp, beläget i den bortglömda, av E4:an dammiga, Mellanbergsparken dit folk kan gå för att bada. Det behövs inga fler simhallar i Stockholm, men ett nytt sorts badhus dit alla olika människor av alla åldrar kan komma och bada i en starkt arkitektonisk miljö - det fattas idag. Därför har jag fokuserat på att gestalta starka rumsligheter där vattnet får stå i fokus och förstärka upplevelsen av rummet. Genom badhuset finns tre olika steg på skalan i material och badupplevelser som går från asfalt till skog, från slutet till öppet. Längst ut mot skogen finns en badsal på 24 x 84 meter där en pelarskog av tegelpelare möter vattenytan.

Opera i Stockholm, Galärvarvet

Quality is the key to a well executed product or service. The construction industry hasn?t highlighted the quality in recent times which have contributed to the construction industry receiving much criticism in the field. The public sees it as an offhanded industry where errors and delays are common.The reason for this is considered to be primarily the lack of time, constant pressure to reduce costs and skills and the ability to communicate between the parties about what the correct quality really means. The industry has begun to realize that it must start setting clearer standards and that there are great opportunities for improvement.This report will give Peab an opportunity to develop their quality work.
