En jämförelse mellan fyra olika energisystemlösningar : För ett hus byggt efter passivhusstandard i Karlstad

AbstractWork to develop the Eurocodes started in 1975 by the European Commission adopted a program to eliminate trade barriers within the construction area. The goal was to create common European design standards that would replace the member countries' own rules. Eurocodes will replace The National Board of Housing Building and Planning, National Rail, The National Road Administration and other agencies' calculation rules for the buildings structures. The transition to the use of Eurocodes looks like this:Eurocodes set to Swedish standards  between 2002 ? 2007They can be used parallel with national standards 2006 - 2009 The total transition is at the end of 2010/2011.Right now is going on a lot of work for replacement of the existing standards to Eurocodes.  The transition to the new calculations` standards, many construction companies and consulting firms facing a big changes and competitions.

Viktstudie av Analysinstrument : Konceptförslag för minskning av vikt

This thesis report describes the development of concepts regarding how weight can be reduced to the analytical instrument Biacore 4000. This thesis has resulted in five different concept proposals, all of which is solutions to reduce the instrument's weight.The thesis started with a pre-study where the instrument's structure and function were studied using both Solid Works, the opportunity to study the instrument in real life were also possible done. During this phase, a weight study was conducted as well, in which the instrument's weight distribution was studied and mapped.Following the initial phase, the work proceeded by developing concrete concepts to reduce the weight of the instrument where focus mainly was on the two cabinets. In addition, another two concepts were revealed, both with a more general approach.At the final phase of the thesis, the concepts were compiled and evaluated among themselves and the initial instrument.The thesis resulted in a study of the instrument's structure and weight distribution, with suggestions on how weight may be reduced for the instrument.The result factors such as materials, and manufacturing were aspects that were taken into consideration.At the final section of the report, suggestions for further work in which different aspects are discussed can be found..

Laborativ matematik-Hur, när och varför används det?

AbstraktHeléne Ingvarsson och Lotta JigrotLaborativ matematik- Hur, när och varför används det?Concrete mathematics- How, when and why is it used?Antal sidor: 37Eftersom vi båda undervisar i ämnet matematik i årskurs 2, kände vi ett intresse för attundersöka hur matematikundervisningen är upplagd och genomförs i de lite äldreåldersgrupperna (årskurs 4-5). Under vår utbildning till lärare i matematik har vi förståttvikten av laborativt arbetssätt i matematik. Syftet med vårt examensarbete är att undersökaom pedagoger använder sig av laborativt arbetssätt i matematik och i så fall hur och hur ofta. Istudien ville vi även undersöka språkets betydelse för den laborativa matematiken.Vi använde oss av en litteraturstudie samt en kvalitativstudie, där vi intervjuade sex lärarefrån olika skolor belägna både på landet och i en mellanstor stad.

Turkiet : Att vara eller att inte vara - Medlem av den Europeiska Unionen

This thesis aims at studying the European Union?s actions against applicant states. In this case Turkey has been chosen as a variable, because of its unique applying accession.Turkey is a country which has been applying for a membership of the European Union since 1989 and Turkey is the only state which has been searching for membership for more than twenty years. Turkey has been given a lot of critic of not fulfilling the political criteria of the Copenhagen criteria?s.

"I världen, men icke av världen" : Konstruktionen av kristen manlighet i Skånes Missionssällskap ca 1939-1945

The aim of this study is to analyze the construction of "Christian masculinity" during the modern era. This is made in opposition to earlier research that has claimed that masculinity could not be constructed religiously, that is, without at the same time being constructed as effeminate or anti-masculine.Using a wide variety of theoretical concepts - such as discourse analysis, class, secularisation, masculinity as constructed from countertypes, and finally masculinity as a homosocial construction - I analyze a free church in Sweden, the Scanian Missionary Society (Skånes Missionssällskap), during the period of ca 1939-1945 (the society was a district of the Swedish Covenant Church, or Svenska Missionsförbundet), in order to argue for the standpoint that masculinity, in fact, could be constructed religiously. The primary source is the society's weekly journal Sydposten.The main results in this study can be summarized as follows: 1) The leading men in the Scanian Missionary Society did, in fact, construct a Christian masculinity, i. e. a masculinity whose core values and ideals were Christian, e.g.

Dikten i "den nya fredens värld" : Litteraturdebatt i tidskriften Samtid och Framtid 1944?1949

This thesis analyses the literature debate in the overlooked Swedish magazine Samtid och Framtid 1944?1949. The magazine was first published at the end of World War II on the initiative of publisher Johan Hansson. After an interesting start, the terms of the debate in the magazine were changed after a power struggle on the editorial level. Thus, the magazine never became the influential arena for literary discussions that it first had potential of becoming.

Stabilisering av betongstommar : Beräkning av en ekvivalent beräkningsmodul med hänsyn till samverkande kort- och långtidslast

Vid stabilisering av betongstommar är det komplicerat att välja en korrekt elasticitetsmodul. Detta då stommens laster verkar under både kort och lång tid. I detta examensarbete utförs en noggrann kryptalsberäkning för varje plans vertikala element, där hänsyn tas till den varierande byggtiden. Utifrån det analyseras kort- och långtidslaster med respektive elasticitetsmodul för att erhålla en ekvivalent elasticitetsmodul som tar hänsyn till de olika belastningstiderna. Denna elasticitetsmodul bestäms efter förhållandet mellan stommens knäcksäkerhet, snedställning och den vindlast som verkar på byggnaden.Den ekvivalenta elasticitetsmodulen ligger till grund för mer noggrann indata än tidigare vid stabilitetsberäkningar och redovisas i diagram som sedan kan användas i det praktiska ingenjörsarbetet.Där inget annat anges utförs beräkningar enligt Eurokod 2.Där inget annat anges är figurerna ritade av författarna..

CARABAS III Konstruktion av antenninstallation på helikopter

This report describes the construction work of a radar antenna for the radar systemCARABAS. CARABAS is a long wave airborne ground radar that has been developed bySAAB Microwave Systems and will now be mounted on a small helicopter, Schweizer 300.The antenna should be able to fold up and down. When the radar is in use the antenna islowered and under transport, start and landing the antenna is folded up. An emergency dropfunction should also be included in the design of CARABAS III.The extent of this report includes construction of the antenna, frame structure attached to thehelicopter, mechanism for folding the antenna up and down and mechanism for emergencydrop function. The mechanical design of the antenna and frame structure is based on modaland stress analysis, vibration measurement of Schweizer 300 and frequency analysis, andcalculations regarding aerodynamic drag and mechanics.The exciting frequencies of the helicopter and accelerations at those frequencies weredetermined by vibration measurement and frequency analysis.

Självkompakterande betong : Ytjämnhet utan efterbehandling

Betonggjutning är ett tungt moment inom byggproduktion och entreprenörer har länge använt betong med flyttillsats för att få en mer lättarbetad betong. Ändå har det krävts långa arbetspass och många tungarbetade moment. Efter lasernivellering, vibrering, slodning och glättning har man kunnat uppnå en yta som nästan är helt jämn. Dock ej så jämn att avjämningsmassa kunnat elimineras för att inte få sviktande parkett eller buktande plastmattor.Självkompakterande betong (SKB), eller vibreringsfri betong som man först kallade den, forskades fram på 80-talet i Japan och dök upp i Sverige i slutet på 90-talet. Det är en betong som innehåller en flyttillsats och en så kallad filler vars gemensamma egenskaper ger en betong som har bibehållen homogenitet samtidigt som den fyller ut formen och omsluter armering endast genom gravitationskraften.

En longitudinell studie om lagervärdering : En studie ur ett samhällsperspektiv

This study concerns how Muslims are portrayed in a choice of twelve news articles from Swedish dailies and tabloid newspapers on the aftermath of the film Innocence of Muslims published on YouTube. All articles are distributed in the newspapers Aftonbladet, Expressen, Dagens Nyheter and Svenska Dagbladet in the period of September 11th, 2012 until September 30th, 2012.For this study, a qualitative text analysis has been embraced and focus has been on van Dijk?s Critical discourse analysis to the texts, with additional features from semiotics applied on the images.The theories consist of Critical discourse analysis, hegemony, ideology and power, postcolonialism and stereotyping.In the qualitative content analysis, concrete examples from the articles are retrieved and commented. These have been divided into various themes, which are trends that the authors have been able to distinguish in the analysis.The result shows that Muslims in the analyzed newspapers are portrayed as the others, unimportant and extremely religious, in a negative manner rather than a positive. Moreover the press has tendencies to generalize Muslims as a group.

Näringsämnesretention i fyra nyanlagda våtmarker i Falkenbergs Kommun

This study evaluates the retention of nitrogen and phosphorus in four newly constructed wetlands in the municipality of Falkenberg, Sweden. The four wetlands have been selected because they have been specifically constructed with the aim to reduce nitrogen and phosphorus in farming areas. The process of selecting the specific wetlands has been done in collaboration with the county administration in Halland. Through field studies in collaboration with the landowners where the wetlands are sited, the areas that provide the wetlands with water were determined. The size of these drainage areas were determined in a GIS computer program. The type of land use within the drainage areas was also determined.
