Hållbar energi : - Ett initiativ till utveckling av bränsleceller i Sverige

In the world we live in today the environmental issues has become increasingly important, and we have begun to realize that we can not continue to use fossil fuels at the rate we do. When it comes to generating electricity we are constantly trying to come up with cleaner and more efficient solutions. The fuel celltechnology is one such alternative and has been around for over 100 years. Yet, it is not until now that the world has started to notice this great technology. The fuel cell has been developed in several areas and can today be used for handheld electronics, vehicles and small settlements.

Växtanvändning i krävande miljöer : en studie i sydvästra skåne

Vegetation is a much appreciated element in our outdoor environment that has many advantages as well for the climate as for people?s health. However in some types of environments vegetation may be problematic. Especially in urban areas with limited space, solid surfaces, pollutions, and warm and dry climate. In these environments vegetations may have difficulty surviving and moreover it may have a negative impact on the environment around it.

Undersökning av solcellspotentialen för golfverksamheter i Sverige

Photovoltaic Systems in Sweden has longbeen heavily dependent on subsidies and grants to bring in a profit for the investor. Production of excess electricity is a major reason for this as the compensation for excess electricity today is low. However, there are businesses that have an electricityneed that are particularly suitable for solar electricity. These businesses have an electricity demand when the sun shines the brightest and if the Photovoltaic System is properly scaled, the excess electricity can be minimized. A golf club is that kind of a business and this thesis aims to examinate the solar power potential for golf businesses in Sweden.Nine golf clubs was selected from different locations in Sweden.

Utveckling och konstruktion av dämpare och låssystem för vågkraftverk

The division of Electricity at Uppsala University is developing a wave energy converter(WEC) consisting of a linear generator connected to a bouy at the water surfacethrough a wire cable called the connection line.During extreme conditions, the wave power plant will experience forces up to 500kN, which lead to unnecessary wear and will ultimately cause the failure of theconverter. To prevent this there is a need for a damper.The wave energy converter works at a maximum efficiency when the translator?sare centered with respect to the stator. Due to tidal movements the position of thetranslator can deviate. There for a mechanical divice that will compensate for this isneeded.This report describes the further development of an earlier project where a tidalwave compensator for a wave energy converter of Seabased AB was developed.

Projektering av ett småhus med fördjupning i uppvärmningssystem

This report aims to examine the design of a passive house. The design addresses the selection ofmaterial, sizing and selection of both building services systems and building technical features suchas load-bearing framework and moisture control. Interior layout is designed for a family of twoadults and one child.A big part of the report is devoted to an in-depth comparison of three different wall constructions ofpassive house standard. The structures that have been compared are a lightweight timber structure, aheavier concrete structure and a sandwich wall of the brand Weber Leca. The report covers variousaspects such as air flow, wall thickness, the risks associated with the construction, U-value, thermalbridges, power consumption, price, and assembly costs.

Utformning & placering av vädringskanaler i ett passivhus, drivet av naturliga krafter

A passive house in Norra Djurgårdsstaden drawn by Tengbom Arkitekter is going to be built. A shaft for airing is needed for a few apartments in the house.The airing shaft is designed for a few two room apartments in the house, which are not able to achieve satisfactory airing, as their outer walls are facing a single direction. The other apartments on the same floor are corner apartments. These apartments do not have the same difficulty with airing since they have their outer walls in different directions, with different pressures at the facades. The airflow in the airing shaft is supposed to be driven only by natural forces, by the sun. The purpose of natural driven forces is to achieve low energy consumption for the house.In this thesis, a design of the shaft for airing has been developed.Initially an open shaft for all apartments was analyzed.

Impleamini agnicione voluntatis Dei : En predikan ur Skoklosterhandskriften

This essay describes my work as a director in a specialized orientation within psychodrama, surrealistic psychodrama. Using the language and performance techniques of theater and under the guidance of a director, psychodrama creates an improvised narrative or story. The essay describes several dramas I have directed, reflecting on my actions and choices as a director and group leader. I examine whether my working method has allowed me to be spontaneous and creative, which I believe the example of "The dangerous bear" demonstrates. The process enabled me to establish trust and receptivity so that a newly constituted group dared to investigate conflicts in symbolic ways associated with illness and death.

County Branding : En studie i kommuners marknadsföring mot företag

There is a mutual dependency between the business world and the country?s municipalities. The municipalities are dependent on the companies to create work and tax income while the companies are dependent on the municipalities they are located in to provide good infrastructure among other things.Apart from this the municipalities can work activly with creating a strong brand in the eyes of the companies and many researchers in marketing agree that marketing of places will be more common in the future. Marketing of municipalities is however still a rather new and unexplored area and it is uncertain how and to what extent the municipalities work with this.The thesis is formulated:How are the municipalities working to market towards companies and is it possible to make out any positive change from these marketing efforts?The goal of this study is:Our goal is to examine how the view of marketing of places differs from different municipalities in the Stockholm region, how some of these municipalities work with this and how far they have come in this work.
