This report is a thesis for collegeengineering program in structuralengineering at Uppsala University andwas commissioned by the Swedishcontractor Svevia. The study aims toprovide an overview of the mostbeneficial bridge material from bothenvironmental and economic point ofview.The life-cycle analysis covers onlycarbon dioxide emissions, since it isthe most spoken of in today?s climateagenda. Furthermore, this study aims tohighlight which parts, of the systemboundary, that contributes to greatercarbon emissions for the wood- and theconcrete bridge.The life-cycle cost analysis wascalculated with a lifespan of 40 yearsand covers the basic cost of investment,operating and maintenance, anddecommissioning costs.The analyzed constructions in this studyare existing projects that are almostcompleted. Both bridges were designed tohandle loads up to 60 tons.

This report treats two assignments that concerns the biofuel furnace at Billerud Skärblacka AB and how these assignments were solved. The assignments were: reducing the number of CO-spikes and tuning the overfire air control loop. To reduce the number of CO-spikes the possibility that skewness in mass distribution affects the number of CO-spikes were study. The skewnwss of mass distribution was controled and adjusted with two experiments. The conclusion that was made is that the skewness of mass distribution were not sufficient enough to affect the number of CO-spikes.

Efficient energy use in the housing sector is crucial for achieving a sustainable society. The expansion of this sector only represents a fraction of the existing houses, hence it?s within the existing houses the potential for energy savings lie. This potential has been analyzed in order to determine if it?s possible to cut the current energy demand in half.

Syfte: Att undersöka vad som utmärker ledarskap i ekonomiska kriser, till följd av den idag aktuella finanskrisen.Genomförande: Empirin har insamlats med hjälp av den kvalitativa metoden. Studien innefattar djupintervjuer med semistrukturerade frågor och tio respondenter från två olika företag inom banksektorn. Utifrån empirin har författarna försökt att dra paralleller mellan ledarnas beteenden och de teorier som omfattar olika ledarstilar.Slutsatser: Utifrån analysen av empirin framgick det att ledarbeteenden i ekonomiska kriser skiljer sig. Dock kan orsaken till det vara företagens olika förutsättningar och struktur innan den ekonomiska krisen. Beteenden som tydlighet, tillgänglighet, delaktighet, samhörighet och minskat handlingsutrymme blev mer utmärkande.

The guest harbor on Utö, Utö Gästhamn, is currently using electricity for heating all of the water used in the showers and taps. Because of the large amount of visitors, especially during the summer months, the hot water usage gets very high and that is also the case for the electrical bills. During the year of 2011 the cost of electricity for Utö Gästhamn reached a total of 257 500 kr. Out of these 257 500 kr approximately 142 000 kr, 55 % of the total cost, were because of the water heating.The report is the result of a cooperation with Skärgårdsstiftelsen, the Green Islands-project and Utö Gästhamn where the mutual goal is to dimension a solar energy system, to promote the sustainable development.Initially the different techniques for the solar energy system are researched. The techniques are plane solar collectors, evacuated tube collectors, pool collectors and photovoltaic cells.

When the Swedish Forestry Act was changed in 1994, brushing of young stands became non mandatory. Since then the annual need for brushing in the country has increased by about 100 000 hectares per year. In later years the price for biomass energy has increased to the same level as pulp wood. The high price on biomass energy and the large areas of stands in the need of brushing has created a new market with its own technical, economical and environmental conditions. There is a development of various techniques to manage the forestry stands with late brushing.

Agile as an idea was created in 2001 through the Agile Manifesto with focus on social relationships, communication and flexibility. This was a reaction to the traditional, hierarchical organization with the goal of restoring balance within organizations in the IT business. Today we can see a transit of Agile from the IT-industry to other industries and areas, such as HRM.There is a challenge in attempting to traditionally control a social idea such as Agile, and there is a lack of empirical studies of the organizational context and its effect on the interpretation of Agile in practice. This study is an attempt to connect Agile to the science of business administration.The purpose with this study is therefore to research the organizational contexts effects on the interpretation of Agile in practice, within IT and HRM. Where Agile is established or well known.To fulfill our purpose we chose social constructivism as our scientifically approach, and conducted 12 in-depth interviews.

This thesis has been carried out onbehalf of Lindborg & Sons in Örsundsbroand is a concluding part of the Bachelorof Science program in ConstructionEngineering at Uppsala University. Theaim of the project is to make a plea fora database of good examples of themachine room types using Revit drawingprogram, and work out a correspondingworksheet .At the start of the process it becameapparent that there were somedifficulties in using Revit to creatingmachine room types of the variety whichthe company builds. For modelling ofoblique, curved and irregular lines, Ihad to use my AutoCAD Architecture andthen import them into Revit.The creation of calculus in Excel wastime consuming. On the other hand, it isa one-time work to create the template.The advantage of Excel is that there isno need for a re-calculation at the costof various types of machine hall. Allthat is needed is to replace the variousparameters.

This is a qualitative study of high school students? definition of their conception of a ?good? teacher. Its purpose is to provide increased insight for teachers about students? ideas of the phenomenon. The study is based on the reports of six respondents, which was later analysed according to the Interpretative Phenomenological Analysis method (IPA).

This essay conducts a descriptive analysis of the ideas expressed by NATO´s official security strategy "Strategic Concept" from 2010 and the European Union?s security strategy "A Secure Europe in a Better World" from 2003. The purpose of this analysis is to examine whether the ESDP and NATO are compatible with each other when it comes to the role of security policy actor. To do so, I´ve chosen to analyse the actors' security strategies based on three dimensions. These dimensions are: Their view of the international scene, their views on cooperation and their views on how to reach security.

Social policy has now received an increased attention in the European Union. The European welfare states experience a high level of unemployment, which the EU now tries to handle through the European Employment Strategy (EES). The core of this essay is whether the welfare institutions of the European member states are integrating through an institutionalization process or not. Within the EU four different types of welfare models can be identified: the Scandinavian, the Continental, the Southern and the Anglo-Saxon. The welfare models differ in the institutional settings e.g.

Researchers and practitioners have recognized the need for ?transforming? every policy of the company into a competitive advantage tool. Thus, both the pricing approach and the supply chain practices of the firm have emerged as an important determinant of success. In this study, however, we are not only interested in these two aspects, but also in a third one-namely cultural conflicts as an obstacle and challenge. The interaction of the tree factors is extensively presented against the backdrop of Skanska and four of their closest Polish suppliers.

The aim of this Master?s thesis is to investigate the meaning the reading group of the public library has to a number of users. To fulfill the aim the following three questions have been formulated: 1) What do a number of users expect from the reading group of the public library? 2) Which approach/attitude or approaches/attitudes do a number of users have to reading and to talking about reading? 3) How do a number of users experience the ongoing reading group?The research is founded on qualitative interviews with five users that take part in three different reading groups in public libraries. The theories that are used is the theory of three so called strategies - the pragmatic, the traditionalistic, the emancipatory ? and the theory of flow.
