This thesis treats Building Information Modeling, BIM, in the production stage. Brieflydescribed BIM is virtual model of a building object where all information about theobject is gathered. All the involved operators in the construction project have access tothe model and can gather or share information about the project. There are several waysto apply BIM in the production stage. This thesis primarily deals with visualization of theobject, preparation and planning, the ability to take amounts from the model andcoordination and clash control.The basic issue was highlighted by Byggdialog AB.

 SAMMANFATTNINGArbetets syfte var att undersöka vilka faktorer det är som påverkar lärare att använda eller inte använda laborativt material i sin matematikundervisning i förskoleklass till och med årskurs 3.Laborativ matematik innebär i detta arbete matematiklektioner där lärare och elever tar hjälp av någon form av konkret material, både vardagsmaterial och pedagogiskt material för att förstå och lösa problem inom ämnesområdet matematik.Undersökningen genomfördes med hjälp av enkäter till elva lärare i förskoleklass till årskurs 3 på tre olika skolor i en och samma kommun.Resultatet visar att samtliga av de lärare som svarade, alltid eller nästan alltid använder laborativt material i sin matematikundervisning, men inom vilka matematiska områden detta sker är varierande.Varför lärare i denna undersökning använder laborativt material eller inte på en lektion påverkas inte av vilken utbildning de har eller om de har någon vidareutbildning i matematik och inte heller av hur länge lärarna har undervisat, utan detta beror enligt lärarna själva på andra faktorer så som: elevens förståelse, tron på metoden, intresse/attityd hos lärare och elevers, tid/lektionens längd och gruppstorlek.Knappt ¾ av lärarna har deltagit i någon form av vidareutbildning i matematik. Alla lärarna som svarade ansåg dock att det laborativa materialet är självklart och nödvändigt för att eleverna ska få en djupare förståelse, då materialet visuellt kan konkretisera detabstrakta i matematiken. Lärarna ansåg också att det laborativa materialet bidrar till att eleverna lär med fler sinnen och att detta i sin tur gör att kunskapen fastnar lättare, matematiken blir även roligare. .

The purpose of this paper is to test a procedure that would be useful for a certain, more final purpose. Assume that you want to know if the differences in the result of a certain effort in health care have any connection with differences between the life situations of the patients. This would be easier to investigate if the life situations of the patients had connection to the easily available variable Health Care Cost (in Swedish VK). In that case the searching for connections between VK of patient groups and the result of health care efforts would be sufficient to gain knowledge of possible connection between health care efforts and life situations. Thus that is the final purpose.

In May 2010 the plans for Malmö?s new Concert Hall, Conference Centre and Hotel were announced publically. The purpose of this thesis was to present strategy for communication in order to gain approval for the new concert and conference center from the inhabitants inMalmö and to incorporate the use of it in their everyday life.Material from the receiver?s as well as the sender?s perspective has been collected from qualitative interviews. Through group interviews we have investigated the general consensus of the inhabitants of Malmö regarding the investment, placing, offered events, expectations as well as how they collected information.

The aim of this report is to analyse the use of the capacity at the CNC (computer numerical control) cutters and show how the level of set up time for these cutters at Stålöv AB. This assignment is concrete whereas there are no subjective questions to this matter and there are only cold figures presented.Production economy is getting more important as the competition hardens and there are several different ways to increase productivity and efficiency in a company. In order to increase productivity and efficiency work studies are used to, through an analysis, find developments in methods that result in improved work methods and to establish the time that are used. Increased production of different parts and customer driven production in combination with increased demands on rationalisation of capital have led to an enlarged interest for shorter set up times in the production.To point out the use of capacity and the set up time of the cutters at Stålöv AB we used frequency studies. Frequency studies are work measure methods based on random observations on predetermined events to calculate the relative occurrence of these events.

Climate and environmental issues is now high on the agenda. We live in a generation that must try to solve some major environmental problems. Buildings and habitations account for approximately 40 % of Sweden's total energy today. To reduce this figure, as needed, more research in the field of energy efficiency is required.This thesis concerns the heating of buildings. The load on district heating is heavy during certain times of the day.

The consumption and energy use in today's society contributes to the on-going climate change that creates a debt of life quality for future generations (www, DN, 2007, a). The resources that are used by humans exceed by far what is sustainable (www, Regeringen, 2007, a). The purpose of this paper is to examine how a message about energy conservation should be designed to reach youths. This will be attempted by showing their thoughts on energy and environmental issues and also what it would take for them to get more involved in these issues. The views of the youths are gained by a number of focus group-interviews, which where carried out in the fall of 2007, with kids in the ages 12 to 19. Apart from these interviews, interviews where also conducted with representatives from different youth organisations in Sweden, which gave their views on how to get a message across to kids.

The production of ferrochromium alloys at Vargön Alloys AB contributes to formation of unwanted ferrochromium dust, which contains toxic Cr(VI). The dust is since summer 2005 treated with an iron-sulphate solution to reduce Cr(VI) to the non-toxic Cr(III). A year later the treatment technique was improved and disposal occurs in cells on the landfill. The cells can be up to 300 m3 and the edges can be made out of fro example concrete. Tests are conducted on the treated dust when it is disposed.

Fukthantering är idag, trots god kunskap inom ämnet, ett stort problem inom byggproduktion då tunga betongstommar ska torkas ut under pressade tidsplaner. Det finns en uppsjö av beräkningsmetoder och hjälpmedel, exempelvis ByggaF och Torka S. Däremot finns inget enkelt sätt att kombinera uttorkning, energiåtgång och kostnader som är användbart i produktionen.Miljön är kanske ett av det här århundradets största samhällsproblem. Lokala brister kan få globala konsekvenser och för att bygga ett hållbart samhälle måste detaljnivån studeras. Byggbranschen är en stor energibrukare där stor vikt på energibesparingar läggs i förvaltningsskedet, medan det försummas i produktionsskedet.

Buildings today are built to maintain a healthy indoor environment and an efficient energy usage which is probably why damages caused by dampness has increased since the 1960?s.A study between year 2008 and 2010 showed that 26 percent of the 110 000 examined houses had damages and flaws caused by dampness that could prove to be harmful later on. This means that one out of four bathrooms risk the chance to develop damages by dampness. Approximately 2 percent of the houses had already developed water damages. It is here where the problems appear.

The level of increased central government that we have experienced during the last decades in school, for the purpose of increasing equality and to adapt the Swedish school to a certain international standard, clearly shows that increased control scarcely leads to improvement.The aim of this paper is to examine whether teachers believe that national tests contribute to equivalent assessment and increased goal attainment. Furthermore the teachers? attitude towards and work with national tests is described. The paper is written from a school improvement perspective, where good examples from current research on what creates increased quality in school meaning increased goal attainment and equivalent assessment are related to research on school effectiveness and increased testing in schools. The study builds upon a quantitative survey among teachers in upper primary - and secondary school in a medium-sized municipality in Sweden.The result shows that the teachers have a somewhat more positive than negative attitude towards national tests, as a whole.

An effective Integration policy is important in Sweden while our government has decided and committed to be a country where everybody will be given the same opportunities. There is a greater awareness in today?s society of integration policy goals such as equal rights, responsibilities and opportunities for all. In a number of areas, however, the disparities between immigrants and Swedish-born citizens are still too large.The Swedish Riksdag decided on integration policy in 1997. The main task for this thesis will be to examine the motive behind the Government's decision to revoke immigrations policy and introduce integration policy.

Deicing fluids based on Propylene glycol are used at Stockholm Arlanda airport to remove or prevent ice on aircrafts. The high oxygen demand of propylene glycol can cause oxygen depletion in rivers downstream from the airport if not collected. Mass balance calculations made by Swedavia indicate that the actual amount of gathered propylene glycol is underestimated. Suspicions that propylene glycol is degraded in the stormwatersystem designed to collect deicingfluids, called the B-glycolsystem, have to be investigated in order to establish with certainty that no propylene glycol in other ways leaves the B-glycol system.The purpose of this study was to determine if degradation of propylene glycol is present in the B-glycol system and also to estimate the extent of the degradation. Propylene glycols high biological oxygen demand can cause oxygen depletion in waters downstream from Stockholm Arlanda airport if not collected.

This thesis was conducted at Mälardalen University in Västerås and Härjeåns Nät AB, mainly in Sveg. Härjeåns Nät AB is a network company that delivers electricity in Härjedalen municipality, Ånge Municipality, Ragunda and Bräcke municipality. The maintenance and dismantling of electricity and broadband networks generates a lot of waste. The purpose of this work is to present proposals on the management of the waste. The goal is that all of Härjeåns offices should have equal management for the waste and an overview of how to manage the various wastes.

The purpose of this study is to shed light on and describe Kramfors travel centers function and relationship to the surrounding urban environment, and how this core is experienced by residents and visitors. To do this, the use of the travel center, its relationship to Kramfors city center and the perception of it, as well as possible improvement areas has been studied.This has been examined using a quantitative method by designing a questionnaire and the usage of a research strategy through the implementation of a small-scale survey. Within this a cluster sampling was applied.The result shows that Kramfors travel centers is primarily used for traveling and is used most frequently by the visitors within the study. It is also shown that residents 'primary reason for traveling from the travel center is friends and family, followed by shopping, and that the visitors' primary motive for traveling is friends and family as well, followed by work. The mode of transportation between the travel center and destinations are mainly walking, while the mode of transport between homes and the travel center proves to be the car.
