Optimering av betong med Byggcement (CEM II) till håldäcksproduktion

This thesis has been developed inassociation with Strängbetong AB, Sweden.A few years backCementa AB introduced a new type of cement on the Swedish market: Byggcement,which is a Portland Limestone Cement. This type of cement is better for theenvironment and cheaper than Rapid Hardening Cement which is used today at SträngbetongAB.Strängbetong AB isvery interested in a change of cement in the factory and wants to know what ittakes to make a transition from Rapid Hardening Cement to Byggcement.This final projectaims at investigating how the workability and strength development are affectedby a transition from the existing cement to Byggcement and how we can change theproperties of the concrete by adding different types of superplasticizers. Laboratory and factoryexperiments were made, to investigate the transition..

Dammsäkerhetsanalys via stabilitetsberäkningar för Långströmmens kraftverk : En jämförelse mellan olika dimensioneringsmetoder

A detailed dam safety evaluation (in Sweden called FDU) was performed in 2009 by WSP where stability control was performed for Långströmmen power plant with associated spillways. This evaluation concluded that stability could not be ensured, and risk of sliding occurred. The evaluation is based entirely on the recommendations outlined in RIDAS, the power companies guidelines for dam safety, and it is clear that extensive renovations are necessary to stabilize the dam.In this work, the stability will also be checked with guidance through new proposals on guidelines for concrete dams sliding stability, ELFORSK?s report 08:59. This report considered the guidelines in RIDAS as oversimplified, both from an international perspective, but also with regard to the current state of knowledge regarding dam safety.

Från Rocky Balboa till Freddy Heflin : En komparativ stjärnstudie av Sylvester Stallone

Vårt syfte med denna kvalitativa studie var att granska hur pedagoger bemöter pojkar och flickor, hur medvetna de var i sitt bemötande och se om det fanns någon skillnad i deras medvetenhet och hur de agerade i praktiken. Metoderna som användes för att få fram empiri var observationer och intervjuer som sedan har jämförts med varandra. Undersökningarna har skett på två olika förskolor, där vi har besökt en avdelning på varje förskola. På dessa två avdelningar var barnen i åldrarna 3-5 år. Det var sex pedagoger som medverkade i studien.På den första förskolan fanns det lite större skillnader i bemötandet.

Genus och informationsteknologi

This thesis discusses how the education in the Master of Engineering program can change to become more into line for the students needs, especially for the women, both directly in the education situation and later in their occupational roles. This is done using a gender perspective. Both the education and the occupation today is characterised by masculine norms and values. The education lacks gender perspective and is created by men, for men. The thesis gives concrete proposals on how to change two existing courses to better fit the students.

Matematiksvårigheter : Klasslärarens arbetsmetoder

The purpose of my study is to contribute knowledge about how class teachers can work with students who are in mathematics difficulties. The question at issues I have is: Which methods can class teachers in grades 1-3 use to help students with mathematics difficulties? and Which obstacles and opportunities are there in this work? To get answers to my questions, I have read relevant literature and interviewed 3 class teachers in central Sweden. Through my interview I learned that education should include and build on concrete materials and methods. I also got to know that time is the biggest obstacle to helping students with mathematics difficulties. Keywords: mathematics difficulties, methods, obstacles, opportunities.

Islastens inverkan på brottsannolikheten för glidning och stjälpning av betongdammar

There are many old dams in Sweden and, since few dams are constructed today, the main task in risk assessment on the existing dams is often to reduce the risk of failure. RIDAS (Swedish Guidelines on Dam Safety) is used when designing new dams and assess the existing ones. The guidelines include stability requirements for different failure modes, e.g. overturning and sliding, which imply that the load effect from e.g. uplift and ice load need to be less than the resisting loads or moments.

Ljudlandskapets Attribut: Metoder för att bättre förstå och beskriva ljudlandskap

In soundscape research, the field?s methods can be employed in combination with approaches involving sound quality attributes in order to create a deeper understanding of sound images and soundscapes and how these may be described and designed. The integration of four methods are outlined, two from the soundscape domain and two from the sound engineering domain. This study has shown that by combining these methods the understanding of both the entire soundscape and the specific sounds increase. The study also shows that when the methods are used, there is a qualitative change of the description and understanding of soundscapes and the concrete description becomes more elaborate..

Erfarenhetsrapportering vid Forsmarks Kraftgrupp AB : Utvärdering av erfarenhetsåterföringsprocessen samt utveckling av ett systemstöd

Organisations constantly live under the potential threat of events and accidents that seriously could harm the organisation. Forsmarks Kraftgrupp AB, the company that this master thesis focus on, is in no aspect excepted from this threat. Through an early identification of near misses and the taking of corrective action in use, Forsmarks Kraftgrupp AB has managed to reduce the likelihood and the consequence of events and accidents. The purpose of this master thesis is to evalutate Forsmarks Kraftgrupp AB?s operation experience process on the basis of IAEA?s and WANO?s requirements within the field of operation experience and to develop a usable system applicably within the field of operation experience.The thesis is divided into two parallel tracks, where one is the evaluation of the operation experience process and the other the design of a usable system, applicably within the field of operation experience.

Tillämpad informationsteknologi i klassrummet

This bachelor thesis in science Informatics contains the qualifications for the applying of IT in education for students in elementary school, grade 1-3. By empirical case study on an existing elementary school, whose success on IT use is noticed, describes how to apply IT in the classroom in an adequate way. We look at different theoretical frameworks in interaction and design of systems designed for learning purposes, and satisfies their specific needs and situations within the classroom's four walls. The current lack of statistical measurements on students' results and effects of the use of IT in teaching, prevents further improvements. If we simultaneously work to develop more well-designed systems that are designed for this purpose, it is possible that the effects become more and better.

Adaption och subversion : Återbruk, mening och nonsens i Block av Ulf Karl Olov Nilsson

The Swedish contemporary poet Ulf Karl Olov Nilsson (UKON) creates his poems by recycling and manipulating existing material. Though the overall opinion of his work has been positive, the idea that experimental poetry focus shape on the expense of content has led critics to either interpret the nonsensical and absurd aspects of UKON?s poetics as a consequence of the technical methods he uses to create his poetry, or to look beyond the nonsensical and absurd aspects to focus the fact that the poems creates meaning at all. The poems of UKON?s sixth collection of poems, Block (2005), differ from each other in many ways: some poems are lists and other revolves around a person ? their content and construction vary and they can hardly be read as an expression of one persons thought.

Renaissance of a CRM system ? Successful re-implementation out of an after market perspective

Problem: Today Frigoscandia Equipment Europe, FSEE, is not sure how their CRM-system, MSMS, is used along with other solutions at the different regions throughout Europe. The company is interested in a usage evaluation describing by who and how the system is used. FSEE is also concerned about the users opinions of future development and improvements.Management is also concerned about how MSMS would support the After Market and gain full leverage of the IT investments. MSMS is today only used to a limited extent in a few of the After Market departments, and FSEE is interested in what an overall usage would mean in terms of improved internal communication, customer focus and information management. The following questions will therefore be investigated in this study:· How, by whom and where is MSMS used within FSEE?s After Market and Sales divisions today?· What does the After Market division at FSEE gain from using MSMS?· What has to be done to improve the usage of MSMS at FSEE? Purpose: The purpose of this Master Thesis is partly to examine the current usage of the Sales and Marketing System within FSEE?s After Market and Sales divisions.

Det uppätna monopolet : Initiativ, inflytande och resurser vid planeringen av kvarteret Druvan genom projektet Mitt I City

The purpose of this essay is to examine if the municipality has a real freedom of action to control the use of the land and the shaping of the buildings in a large and prestigious building project.In Karlstad there is now (2006) a large building project in form of a shopping mall. This project is in its final stage of completion and offers me a suitable case to examine. To undertake the purpose of the essay, the following research question is formulated:Do the municipality have a real freedom of action to control the use of the land and the shaping of the buildings in a large and prestigious building project as the Mitt I City project?In an attempt to examine the project and the planning process, three themes are applied. The first theme derives from the hypothesis that the part that initiate the process gets the upper hand as future discussions are taking place in relation to the original ideas.

Rakt på sak! : Ett arbete om effektiva och funktionella webbtexter

Den ökade tillgången till internet i svenska hem betyder att vem som helst har tillgång till olika typer av information. Samtidigt ökar omsättningen hos den svenska detaljhandeln, både i butiker och för den svenska e-handeln. Därför ställs det högre krav på webbtexter, så att alla kan förstå dem.Den här studien handlar om hur webbtexter, i form av artiklar, bör skrivas på Elgigantens svenska webbplats.

Det ska leda fram till vad som kan förbättras för att skapa effektiva och funktionella webbtexter som riktar sig till en bred målgrupp.Begrepp hämtade från informationsdesign, klarspråk och användbarhet på webben ligger till grund för de kvalitativa metoder som har använts i den här studien.

Pojkars läsning : -en kvalitativ studie av pojkars läsvanor i årskurs 8

I detta forskningsproducerande arbete undersöks en grupp pojkars läsvanor i syfte att se vilken typ av litteratur deföredrar att läsa samt vilka attityder de har till läsning. Bakgrunden till denna studie är författarens examensarbete isvenska som behandlade pojkars förhållande till skönlitteratur. Undersökningen som ligger till grund för dennauppsats är strukturerade skriftliga intervjuer, genomförda med tio pojkar i årskurs åtta.Resultaten av studien som genomförts visar på att de flesta pojkar har en dålig attityd till läsning av skönlitteratur.Många föredrar istället digitala medier som TV, film och datorspel. Läsningen kopplas många gånger endast tillskolarbete och inte som en del av pojkarnas fritidsliv. Läsande förebilder pekas ut som en viktig del i formandet avpojkars attityder inför läsning.

Den kompetente läraren - Yttre och inre ramfaktorer och deras inverkan på undervisning

Title: The competent teacher-external and internal frameworks and their influence on educational praxis. This thesis is about what kind of approach a teacher (may) consider when he is facing parameters that he can not do anything about, in this case represented by political, educational och social frameworks. One of the things a teacher can do to adapt to the situation is to see what possibilities he has to develop and expand his topic. The study is built on action research and was carried out during a nine months period on an upper secondary school in Malmö, Sweden. The object of reasearch is myself as a teacher and in my result I describe how various educational situations were handled.
