Bränsleceller i personbilar : En teknoekonomisk well-to-wheel analys av vätgas som fordonsbränsle

Several technical solutions are ready to step forward as the new generation of propellant, and this report aims to explore the possibility of commercializing fuel cell cars. The report is based on current research and data from today's technology and engineering solutions that are estimated to be commercially realized before 2020.A mapping of today?s different fuel cell options has shown that the most suitable fuel cell option is the Proton Exchange Membrane Fuel Cell, which uses hydrogen as fuel. The report is focusing on a techno-economic well-to-wheel analysis of hydrogen and the energy balance and costs in a system perspective. The basis for this analysis consists of two centralized methods of production, steam methane reforming (SMR), and alkaline water electrolysis.

En pilotstudie av unghästars användning av ligghall i grupphållningssystem

Today, individual indoor stalls and individual outdoor paddocks are the most common way to house horses in Sweden. The way that we manage, house and feed the horses are not optimal for the species natural basic behavioural needs. However, the awareness of this grows in the context of research and the emergence of alternative housing systems. One of the Alternatives to the traditional format in individual boxes is called group housing. Group housing systems allow horses to live in herds and they can choose how they want to distribute the hours of the day between movement, resting and foraging. The purpose of this study is to examine how frequently the young horses in a group housing system use the indoor lying area.

Global Ethics in Dialogue : Church Studies on Globalization in Relation to Global Theories of Justice

The globalization of political and economic processes is a growing moral concern for theologians and political philosophers alike. My thesis aims to outline, analyze, and compare church studies of globalization with global theories of justice.To do this, I draw upon recent studies of globalization made by the World Council of Churches (WCC) and the Lutheran World Federation (LWF). The WCC and LWF are two global reaching church organizations. They have a common aim of uniting churches for ecumenical dialogue and are involved in social, economic, political, and ecological questions. The WCC and LWF analyze globalization by applying biblical and theological principles from the Christian tradition.

Norge - finansieringen av den åldrande befolkningen

As most developed countries Norway has an ageing population meaning that the number of pensioners is predicted to grow rapidly over the coming years. As a consequence the Norwegian pension system will not be able to provide for these future pensioners. Meanwhile, a rising number of early retirees and disability pension claimants is diminishing the real retirement age. Also the individual pension amount is growing while the pension system itself reaches maturity. In short, major reforms are needed in the Norwegian pension system.

Hållbara uppvärmningsalternativ för Grinda Wärdshus : En studie om uppvärmning med pellets och flis

Energihushållning och varsamhet för äldre byggnader : Chefsbostaden i Strömsholm, ett timmerhus från 1900-talets början

This report is the result of a degree project in building engineering, at an advanced level. The project evaluated a building from a technical and historical point of view, and focused on its energy consumption, particularly the energy used for heating. The building in question was a small apartment building in Strömsholm, Sweden. It was made in 1902, from vertical logs, a not so common form of the traditional log house. The goal of the project was to evaluate if the energy consumption could be reduced in accordance with building preservation regulations, that is without damaging any of the building?s cultural or historical values.The building was surveyed with the help of archive and literature studies, interviews and inspections.

Förekomst av penicillinkänslighet hos blododlingsisolat av Staphylococcus aureus

Staphylococcus aureus is the most clinically important Staphylococcus species and is associated with high mortality in patients with positive blood cultures. S. aureus bacteria may cause a variety of disease manifestations ranging from minor skin infections to life-threatening conditions such as pneumonia, meningitis, osteomyelitis, endocarditis, toxic shock syndrome (TSS) and sepsis. This microorganism belonging to the gram positive cocci may also be part of the normal flora. In Sweden, penicillinase-stable penicillins are the primary Alternatives to treat S.

Konsumentens dilemma : ekologiskt eller konventionellt?

A majority of Swedish consumers have a positive attitude towards organic production and the number of organic products on the market is increasing. Despite these positive trends, there are still relatively few consumers who choose to buy organic produced products. According to statistics, only 3% of the total sales of food consist of organic products. The aim with this essay is to understand what is needed, both from the grocery store and the consumer's point of view, to increase the consumption of organic food. Information has been collected partly through questionnaire with consumers and partly through analysis of sales statistics for a selected numbers of products. Then the empirical material have been analysed in the light of a combination of the Behavioural Perspective Model (Foxell, 1997) and Kotler's Four P:s (Kotler, 2002). Consumer's willingness to buy organic products is influenced by a number of different factors. One important thing is if the grocery store offers a behaviour setting that stimulates the consumers positive attitude and facilitates their possibilities to collect new information. Furthermore, the store needs to offer a broad and well-visualised selection of organic products.

Svenska hushålls vedarbete : en fallstudie i Umeåregionen

In Sweden there are 354 000 private individuals owning forest. Of these forest owners there are at least two thirds that are self-employed, which means that about 215 000 forest owners conduct some kind of work in their own forest. Those numbers do not refer to firewood production, but every year 7.3 million piled cubic meters of firewood are used for heating Swedish households. This implies that many households are also producing firewood. The objective of this study was to assess and analyse the small-scale firewood production in the Umeå-region in terms of persons engaged in the work, equipment used, produced volumes and share of forest-owning households involved in these activities. According to results from a questionnaire, the average firewood producing person is a man between 40-60 years old.
