Process optimization in the steel plant
Blast furnace is the heart of every steel plant. Steel production is based on the blast furnace process, as it is where the iron is extracted from the iron ore and turned into liquid iron, which will subsequently be used to make liquid steel. Therefore, without hot iron, steel can not be produced. Blast furnaces in this process are supplied among others with pulverized coal. Raw coal should be prepared for the blast furnaces in the form of fine coal powder.
Fjärrvärme - ny lokalisering av kraftvärme i Enköping
The municipality of Enköping is presently working out a new layout plan for the town of Enköping and new residences are planned in the harbour area. Because of these plans, the municipal energy company ENA Energi may have to move its location from the harbour to another part of the city.The aim of this degree project is to investigate the possibility of building a new CHP plant in another area of Enköping. The future demand on district heating and infrastructure at the new location have been projected. A new CHP plant has been dimensioned and economic analyses concerning the project have been made.Results show that the future demand of district heating in Enköping will differ a little from the present needs. In 2030, the district heating production is expected to be c.

Today´s roofing of dwelling houses is a very time consuming procedure, which includes a lot of different steps on the construction site. Not only does it cost a lot of money, but often do problems with rot and mold occur in the attics of houses today. The use of prefabricated modules has seen a great breakthrough in the field of construction of dwelling houses; at least when it comes to foundations and walls, where this type of approach makes the construction process way more efficient. What no one previous has succeeded to develop is a corresponding system for roofs that meets the demands of a dwelling house. Accordingly the goal of PlusTak has been to come up with a proper module system for roofing of dwelling houses, where the roofing is completed to meet the demands of the Scandinavian market. During the project a lot of effort has been put into customer contacts and the usability of the product, as well in the manufacturing process as on the construction site. This development has gone hand in hand with several practical tests and tryouts.
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.
Individanpassningens ytterligheter : Några betygsmässigt hög- respektive lågpresterande gymnasieelevers åsikter kring engelskundervisningens utformning.
In today?s society there is a discussion regarding students? level of knowledge and personalisation. The classrooms consist of heterogenic groups of students with different learning needs and levels of knowledge. The purpose of the present study is to find out how the students who participated perceive the teaching of English as an additional language with regards to personalisation, and how they believe differentiation can help develop and deepen their learning. This study has been conducted using a qualitative method with interviews as the core, complemented by observations. The results have been analysed and interpreted hermeneutically. The results show that those students who have a positive attitude to English education, irrespective of their grade, are those who see the benefit of knowing English outside the classroom, and thereby create a connection between reality and studying English.

Tilläggsisolering inom byggnadsvård
Främsta anledningen till en tilläggsisolering är att det önskas bättre energihushållning i en byggnad. Detta kan göras med olika material och olika tekniker. Inom byggnadsvårdssammanhang förs det en diskussion om de fuktbuffrande materialen är bättre vid tilläggsisolering då de är hygroskopiska än de icke hygroskopiska som är mest frekvent använda i det konventionella byggandet. Denna rapport utvärderar om det finns några dokumenterade fakta som styrker att de hygroskopiska och ekologiska materialen fungerar bättre i byggnadsvårdssammanhang än de icke hygroskopiska. Olika isolermaterial från de två nämnda grupperna jämförs utifrån olika parametrar..
Upprustningsmetoder för en bankropp : En jämförelse ur ett LCC-perspektiv
In recent years, the Swedish railway track system has been neglected in terms of capacity and maintenance. To adapt the existing system to current traffic load there is a great need for extensive improvement and maintenance. Shortcomings are especially occurring on older embankments running over soft subgrades. To select the most suitable method for reinforcement of the embankment, it is important to evaluate different solutions from a life cycle cost perspective. In long-term perspective, it is often shown that a method with low investment cost causes a higher maintenance cost and a shorter technical lifetime.
Energikartläggning av Fridhemsskolan 16:2
Increased energy consumption in the world has created an increased supply of various fuels, especially fossil fuels. The Swedish government has set up various energy targets for 2020. To reach these goals it?s important to increase the energy efficiency in local buildings such as schools. This work illustrates the breakdown between energy supply and energy losses over the school.
Restenos efter PC1 (ballongvidgning i hjärtats kranskärl): Upplevelser ur ett patientperspektiv
Background: The intention of this study was to clarify the patients perspective of what it means to suffer fiom documented restenosis after one or more Percutaneous Coronary Intervention (PCI). Aim: The aim of this qualitative study was to ascertain the patients experience of restenosis. Method: Nine patients were interviewed. They had undergone at least one PC1 and two had also undergone Coronary Arterio Bypass Grafting (CABG).

Kombinationsverksamhet - flera verksamheter inom ett lantbruksföretag
In today's Sweden there are approximately 23 000 combination companies, and most of them have a connection with the agricultural sector. The most common type of additional operation is some form of contracting.The aim for this degree project is to answer the following question: which problems and key factors exists within combination operations? The main topic will be within coordination and management questions within agricultural companies with an additional operation.Litterateur written earlier within this subject will be used in this thesis. Mainly litterateur which contains information about combination companies and diversification of some sort. There are also other theories used in this thesis such as; resource based theory and decision making theory in order to understand the problems and key factors within combination companies.In order to investigate the aim of this thesis we have chosen to perform two qualitative interviews with the managers of two different combination companies.
Utvärdering av energieffektiviseringsåtgärder på Bokelundskolan i Växjö
The purpose with this report is to examine how the implemented energy efficiency measures on Bokelundskolan in Växjö have had impact on the energy use. The measures which have been implemented are, new ventilation system, new heating system, optimized adjustment of the heating system, new windows with U-value 1.2 and lower window height, insulation under windows and in the crawl space. The school's energy use before and after rebuilding has been calculated with the calculation program, Vip-Energy 1.5.5.Calculations of energy use for the school with windows on U-value, 0.9 and 0.7 have also been done. The replacement of windows has been studied from a cost perspective. The conclusion is that the exchange of heat and ventilation system was the biggest contributor to reduced energy use on Bokelundskolan.

Optimal väggisoleringstjocklek på hyresfastighet vid begränsad byggyta
Miljömedvetenheten och ökat intresse för energieffektiva hus har gjort att byggnader isoleras som aldrig förr. Oftast är det på lång sikt ganska så lätt att räkna hem en ökad isoleringsmängd och det är just den ekonomiska vinsten som brukar lyftas fram som det främsta argument varför en beställare bör välja den tjockare isoleringen. För en beställare av hyresfastigheter är det oftast ekonomin som avgör ifall ett projekt ska påbörjas eller inte och denna studie ska därför vara en hjälp till att välja den mest ekonomiska isoleringstjockleken i väggar.Syftet med denna studie är att utreda var den optimala väggisoleringstjocken hamnar på en hyresfastighet med flerfamiljsbostäder som byggs på en begränsad byggyta. Inte sällan finns det krav på maximal byggyta från kommunen och då innebär det att ju tjockare isoleringen är desto mindre blir den uthyrningsbara boytan.Kvalitativa intervjuer låg till grund för att bestämma några vanligt förekommande ytterväggskonstruktioner som isoleringen sedan skulle optimeras på. Dessa ytterväggar placerades på en teoretisk referensbyggnad som därefter energiberäknades med hjälp av handberäkningar där matematiska uttryck för en varierande isoleringstjocklek användes.
