Torkning av flis med restvärme : Metoder för att sänka återledningstemperaturen
The purpose of this study has been to evaluate whether a Low temperature bio-mass dryer could be integrated with the local district heating system in Malå. The aim is to increase the thermal efficiency of the cogeneration plant in Malå, by lowering the temperature of the cooling medium. Another benefit that comes from this is improved combustion efficiency at the power plant, since drying the fuel causes an Increase of the heating value.Simulations has been made in Excel, and with use of linear regression, to find out if it is profitable. Data for this purpose has been supplied by the power company Skellefteåkraft and furthermore SMHI.The result of the Calculations shows that a very efficient bio-mass dryer is needed, if yield of investments should be made possible. An Investment of 4,27 Mkr, in a dryer, could at a such criterium return 60000 kr/year, if the price of the biomass is 190kr/MWh.
Investeringskalkyl baserad på ett flerbostadshus energiprestanda
The aim of this study is to find a method to incorporate the energyDemand of a building in the investment cost estimate.The study is based on an actual apartment block. The significant energyaspects are identified, and changed to more energy efficient options.These are then simulated using the energy calculation program VIP+.The calculated energy need is used in the investment cost estimate, andthe simulated alternatives are compared in regards to their economicalprofitability.Depending on the focus, different alternatives are the most advantageous.Since this study aims to show which alternative is the mosteconomically profitable, the annual profit is the parameter of mostimportance. This means that individual measuring of heating and hotwater use is the recommended change of the original house. A changeof the windows to new ones with a U-value of 1,0 as well as 0,8W/m2K also results in a positive change of the annual profit comparedto the original house..
Design och implementation av konfigurationsverktyg för funktionsblock
Abstract In high voltage substations there is an increasing Demand for computerized equipment, and automation of operation and supervision. The future primary equipment will provide the possibility to collect more information and to provide better control for improved effectiveness. Since ABB has got a large customer target, each product must be custom made to fulfil the customers (often from different countries) Demands. Later these products will be configured by engineers who may not be familiar with the tools used at ABB. This is a very expensive and time consuming.
Jämförelse mellan sojaböna och åkerböna som proteinfoder till växande grisar
The soybean can be used in multiple ways, and its high oil content makes it suitable for extraction. Soy bean meal, a by-product of the oil extraction, is a good source of protein with a high feeding value, and is therefore used in a number of different animal feeds. Further, soy bean meal has a low production price, which is one of the reasons for the extensive export of the product. There is a great Demand for vegetable-based proteins, especially in the organic production where synthetic amino acids are banned. However, the current production of soy beans is not environmentally sound and that combined with the long transport distances amplifies the need of finding a locally produced protein source.
Hur påverkar nya religiösa rörelser medlemmarnas Identitet? : En kvalitativ studie i avhoppares uppfattning.
The purpose of this study was to try to develop a better understanding of the process that being a member in a new religious movement might imply, and to find out how the identity of a defector changes from the time upon entering the movement, while they are within the movement and after leaving the movement. We also wanted to examine what kind of help and support would be needed around a defection. The study focuses on identity and our questions were: How does the defector describe him/herself and his/her identity before joining the new religious movement until the period after defecting? What Demand for support and help may there be when defecting from new religious movement? The theoretical starting point was The Identity Theory, Structural Role Theory and KASAM. A qualitative method was used and four defectors from new religious movements were interviewed.
Implementation av offline-läge i mobila applikationen GreatRate
Även om de flesta av oss i dagsläget vet att våra mobila enheter kan tappa sina nätverksanslutningar lite då och då har det mer eller mindre blivit en självklarhet att i alla lägen ändå kunna använda våra favoritapplikationer som vanligt. Denna rapport syftade till att hitta en lösning på problemet med nätverksberoende applikationer genom att implementera ett offline-läge som kringgick detta beroende i GreatRate, en iOS-applikation för kundundersökningar i butik. Med hjälp av en databas för att mellanlagra data under tillfällen då en duglig nätverksanslutning inte fanns tillgänglig samt synkronisering av nämnda data när anslutningen åter blivit funktionell förväntades problemet kringgås. Resultatet blev som väntat en applikation som gav användaren en förhöjd användarupplevelse helt oberoende av nätverksanslutningens status. Några av slutsatserna som drogs var dock att flera olika lösningar finns för detta problem och att problemet högst troligt har olika utseenden för olika applikationer..

Gerd Enequists personarkiv
The Swedish geographer Gerd Enequist (1903-1989) left behind great amounts of private and work material when she passed away. This was donated to the University Library of Uppsala, Carolina Rediviva, in three different accessions. This resulted in three different record. The subject of this report is the progress of assembling these record into one complete record.The registering led to many important decisions such as the role of provenance and the relation of private and public documents. Above all the special nature of personal archives have been a topic of discussion.
Investing in commodities - Will commodity futures enhance risk-adjusted return in efficient portfolios?
With this paper we intend to investigate what kind of benefits there are by adding commodity futures to a well-diversified portfolio. Since the last fifteen years the commodity speculation has grown tremendously, which partially can be explained by that commodities exposes the investor to certain factors other than an investment in equities. According to our calculations the commodity futures have outperformed stocks during our research period, which partially could be explained by the increasing Demand of physical commodities in developing countries e.g. India & China (Akey, 2005). By constructing different portfolios consisting of equities and corporate bonds we could investigate whether our portfolios will benefit from commodity futures and how this will vary over different levels of risk.

Hållbart jordbruk inom vattenskyddsområde : En studie om Sverige, Danmark, Frankrike och Tyskland
To guarantee protection of our drinking water, water catchment protections are established. These are divided into three different zones and in the first zone it is most likely that an activity, such as agriculture, will contaminate the water resource. Hence the activities are strongly regulated or banned. The EU communion is working towards a sustained water quality through several directives; Nitrate Directive, Waterframwork directives and Sustainable use of pesticide directive. The main purpose is to regulate the diffuse pollution from agriculture.This thesis is about how Denmark, Germany and France are working towards a sustainable agriculture within water protection areas.
Energisystemanalys av ABB AB LV Motors
With a larger awareness of the climate changes and increasing electricity prices, energy efficiency measures in the industry have become more common. By rationalize the activity and by the same time decrease the emission of greenhouse gases the company can both save money and reduce negative environmental impact. For the Swedish industries the electricity price have traditional been relative low, which has resulted in a considerable larger usage than other European countries. By a deregulation of the European electricity market the electricity price will level off between the countries, which will cause a higher electricity price in Sweden than we are use to. To prevent that the Swedish industry don?t lose competitiveness against the other European countries, it will require energy efficiency activities in all different forms.ABB Sweden has decided to decrease their total energy usage with five percent in two years.
Vilket matematiskt material finns i den fria leken på förskola : vad väljer pojke respektive flicka
This research is about different perspectives, offered by three mother tongue teachers, one principal and also featuring a representative from Skolverket, on the subject: teacher legitimation for mother tongue teachers, mother tongue teachers opportunity for competence education and the future of mother tongue education in Sweden.The theoretical framework is mother tongue language, globalization, the post-colonial theory, power and social inequality. A qualitative approach was used including five interviews taken place in Stockholm, the results does not however represent the whole country nor the community of Stockholm itself.The result shows that mother tongue teachers thinks the teacher legitimation does not mean anything regarding their already low-status. Even principal and representative from Skolverket express their concern towards the 'non-Demand' for mother tongue teachers to get their legitimation and they feel there is a lack of ambition from decisonmakers to include the mother tongue teachers.As per today there is no higher education for mother tongue teachers leading towards an exam. Mother tongue teachers are worried about their future although principal and representant takes a bright outlook. .
