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.

Jämförelse av frånluftsvärmepumpar
In order to reach the environmental targets, set up by the EU, there are many measures taken to make Sweden more energy efficient. In the housing and real estate sector, an installation of an exhaust air heat pump that reuses the heat in the exhaust air in order to lower the amount of acquired energy, is an example of such an action. The recovered energy can then be used for heating of radiators and tap water. This report aims to evaluate and compare three different systems using exhaust air heat pumps regarding COP, degree of coverage and cost savings. This study was delimited to only account for apartment buildings.The theory chapter describes the different conditions and factors that affect a building?s energy balance.
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.
Nei til EU : Är det rationellt för Norge att stå utanför EU?
The purpose of this study is to illustrate why Norway is not a member of the EU from a rational choice perspective. In order to fulfil this purpose, two questions will constitute the framework of the study. These are:1. What are the arguments of the EU-opposers in the Norwegian EU-debate?2.
Barn med språkstörning möter svenskämnet i skolan : föräldrars berättelser
The overall aim of this study is to clarify the situation in school for children with language disorder from the parents? perspective.Data were collected through five interviews with parents who have children of different ages and with various diagnosis within the language disorder spectra. A qualitative method based on a narrative inquiry was used and each interview was based on a interview guide with the following themes: the child?s difficulties, starting school, the school?s pedagogy, homework, action plans, participation and the future.Each story has its own themes, but there are also themes that are common in all interviews. One common theme in the parents? stories is that school has a lack of knowledge when it comes to language disorder.
Vi och dom och valdeltagande. En studie kring valdeltagandet hos naturaliserade svenskar och invandrare.
This thesis focuses on the problems involving immigrants and their voting behaviour in Sweden. We presuppose that immigrants vote in a far less extent than Swedish citizen according to general statistics. We try to explain and give solutions to this problem. To our help we use both integration theory focusing on multiculturalism and electoral participation theories.Starting off in these two theories, we have further analyzed a number of policies issued to solve the participation dilemma. The policies were issued in order to elevate the socio-economic standards, inform citizens and close the distance between voters and politicians.Our results show that what work best is long term ventures aiming at integrating immigrants to the Swedish society.
Vad och varför: elevers intresse för historieämnet och dess innehåll
Syftet med uppsatsen är att undersöka gymnasieelevers intresse för historia som skolämne med utgångspunkt i didaktikens grundfrågor (vad och varför). Detta för att jag vill bilda mig en uppfattning om elevernas inställning och syn på historieämnet och ämnesinnehållet som en inledande del av ämnesplaneringen och historiekursens upplägg. Arbetet ger en översikt av tidigare forskning kring historieintresse och historiedidaktik samt forskningsresultat från liknande större undersökningar. Med hjälp av enkätundersökningar ville jag studera elevernas intresse för historieämnet och vad de intresserar sig för bland ämnesinnehållet samt varför de är intresserade av historia. Sammanfattningsvis pekar mina resultat på att eleverna har ett någorlunda stort historieintresse och att de anser ämnet som viktigt att läsa i gymnasiet.
Individuella utvecklingsplanens inverkan på undervisningen vid högstadiet : Specialpedagogers uppfattning om den individuella utvecklingsplanens integration vid högstadiet
The aim of this essay has been to find out whether the individual development plan does make it easier to teachers to discover any needs of the students to get education or material changes and by that make adjustments in the classroom. I chose to seek information by interviewing special educators at four compulsory schools, since they have an overall apprehension of how the work is carried out at the school, especially the work with students in need of any form of extra support.All students at the Swedish compulsory school shall have an individual development plan. The purpose with the plan is, besides that the student is to be given possibilities to form his own pedagogical and social goals, that the teacher shall get early signals if a student may be in need of getting education and materials changed and adjusted for to easier manage his studies. The individual development plan of the student should have the function as a tool to the teacher to facilitate for his students.The answer of my question can be sum-up in a no, the inherent potential in the individual development plan is not utilized by the teachers that seem to have the apprehension that the plan is for the student all by him/herself. The teaching staff has obviously not understood the use they can get out of it. .
Att inleda ett arbete med CRO inom webbutvecklingsföretag
This study test the short-termism of companies listed on the market OMX Stockholm 30. We will use a deductive point of view where the purpose of this study is to investigate whether corporate short-term returns can be explained by the independent variables related to corporate governance and compensation practices. This is to investigate whether there is an intentional action on raising the short-term return in order to achieve a higher CEO compensation. In the study, theories dealing with corporate governance and agency theory have resulted in two hypotheses. Basic Hypothesis H1 is: if short-termism of Swedish industry due to the company's short-term returns can be explained by the independent variables related to the company's management and compensation. This hypothesis could not be verified through the quantitative study. Alternative Hypothesis H2 is: the compensation of a CEO can be explained by the independent variables related to company performance and size.
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.
Upplevelser av skam och avvisande hos deprimerade unga vuxna
Depression in young adults is a serious condition causing serious suffering for the victim. By finding risk factors for depression the opportunity for early preventive action is increased, which, in turn, may prevent a negative course. Two risk factors which have been shown to be related to depression are shame and rejection. Therefore this study examined the relationship between shameproneness, rejection sensitivity, shame-related events and depressive symptoms. The self-report questionnaires used were TOSCA, RSQ, Shaming index and BDI-II.
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.
Riskhantering i vägprojekt : Effekt, nytta och förbättringar
The aim with this thesis is to study the risk management in construction projects at the Swedish Road Administration, SRA. Furthermore, the aim is to find the effects of the risk management. The theorem of this thesis is that the positive effects of the risk management in construction projects create additional value to the project. These additional values are that the project itself becomes resilient and that the project goals are achieved without any significant disturbances.This thesis shows that the risk management in construction projects do not follow the guidelines set out by the SRA. This is due to a lack of education in the method and a difficult method all together.
