With the increases in fuel costs due to the depletion of the world oil reserves and the increase of greenhouse gasses as a consequence to using oil as a fuel many companies are looking to new and innovative ways to power their aircraft. One of these new ways to power an aircraft is using fuel cells powered using hydrogen and oxygen, thus producing nothing but water vapour and small amounts of nitrogen dioxide as well as trace amounts of other emissions. Both Boeing (1) and Politecnico di Torino (2) have shown that it is possible to build an all-electric aircraft powered by fuel cells. Both flights used small, two-seater aircraft and a constant between them was the loss of the co-pilot seat due to weight and lack of space. As this paper will deal with a commercial aircraft a primary concern is the cargo and passenger capacity and whatever impact switching propulsion system has on these.

This is an investigation of a mobile prefabrication factory´s competitiveness and profitability which also will result in a suggestion for a design of the factory. The mobile prefabrication factory is an idea of a new concept for production which is meant to be used in the manufacture of slab. The main intention with this concept is that by using a fast established prefabrication factory to produce elements near the construction site, thus avoiding transport from the factory to the building site. This means not only an environmental and economic gain, but also that you can avoid risking damage the elements which often occur during transportation. The contractor is owner of the mobile prefabrication factory and can thus avoid long waiting times and cyclicality.

Environmental issues are global problems and they are a major challenge for any successful organizational business worldwide. Many challenges and opportunities emerge during the certification process of an EMS. Therefore it is interesting to contribute in understanding these emerging problems during this process.The aim of this study is to explore how the environmental objectives could be achieved at preschools in Uppsala, investigate the perceived challenges and opportunities and to identify the outcome of implementing the ISO 14001, Green Flag at such set up.A qualitative method is used and three Green Flag certified preschools, affiliated to the Uppsala Municipality and located at different geographical location were selected. A structured interview with the environmental representatives from the preschools and the municipality was completed. The so-called PDCA-cycle as a method of evaluating sustainable development and analysing the imperial data is used.The study showed that environmental certification constitutes a great challenge for the municipality of Uppsala.

Is it possible that by planning in a more sustainable way when building a new area, we can improve our environment?Most environmental problems are created in cities and therefore they should hold the solution. Through a more ecological urban planning a better foundation for sustainable housing could be created.This report follows the process in coming up with a proposal for a master plan for an area in Odense, Denmark. By going through principles for sustainable urban planning made by different organizations and persons and from these extract main principles, a background is founded to continue the proposal from.Denmark works a lot on expanding their green areas, maintain the existing ones and recreate what?s being destroyed as cities expand.

Abstract Title:                       Grades at Primary School ? A study of local politicians' arguments in                       connection with the division into grades at Swedish primary schools.Author:                       Annie LinderUniversity of KalmarC-essay in Social StudiesAutumn 2011 The study aims to investigate local politicians' decisions since municipalities took overSwedish primary education in 1990/91. The arguments put forward in support of how stages are organised have been studied, likewise whether municipalities have acted rationally when making their decisions.Six municipalities are included in the survey. They were divided into three educational categories: lower, middle and high level schools; previous and recent schools and F9 schools with pre-schools and primary schools integrated.Minutes from politicians' and civil servants' meetings have been studied and categorised according to arguments for and against. The most common supportive arguments are about economy and organisation, others concern school premises, trends and the wish for a comprehensive compulsory school.

This Masters Degree thesis aims at giving an answer to what underlying ideologies are at work in digitizing our cultural heritage. Other questions to be answered are who are benefiting from a digitized cultural heritage and who are not, and what different opinions about digitizing our cultural heritage can be identified. Two studies are made in this thesis, one of Swedish political documents that concern digitizing our cultural heritage, libraries, museums and archives, and the other one is a study of documentation of three Swedish digitizing projects. In the first study three different, but closely associated ideologies are identified, namely a preserving, b giving access and c a mixture of both, and these are shown in a model. In the second study this model is then used to identify the ideologies of one project from each sector of the so called ABM-sector Archives, Libraries and Museums.

The purpose of this master thesis is to examine how Dublin Core corresponds to the findings in the IFLA report Functional requirements for bibliographic records FRBR, and what consequences this correspondence has on the usability of Dublin Core as a bibliographic standard. While the study describes the conceptual model of FRBR and the entities work, expression, manifestation and item, its main focus is the mapping of attributes and relationships to the user tasks defined, namely to find, identify, select and obtain entities. The study makes a comparison between data that FRBR rates as highly important for any user task, and the elements defined in DCMI Metadata Terms. The outcome of the comparison is then analyzed as to how it affects Dublin Core's possibilities to assist in the different user tasks, and common problems are discussed. The results show that problems in expressing attributes and relationships through Dublin Core elements concern all of the four user tasks.

Germany has experienced low birth rates ever since the 1970s when they fell below the replacement levels of 2,1 children per woman. Since then, their birth rate has been around 1,5 children per woman, which has caused an overall aging population. The consequences of the declining birth rates is that the previous generations are becoming larger than the younger generations. This demographic shift raises concern about how its potential implications might affect different aspects of the country and its economy overall. The aim of this paper is to try to discern the dynamic between the share of the labor force in relation to total population, with the share of pensioners in relation to the total population.

After the storm Gudrun in 2005, the Swedish Transport Administration started clear-cutting of railroad corridors to reduce the risk of trees falling down on the tracks. Simultaneously, train accidents with moose and roe deer have become more frequent and the costs for consequent delays and repairs of engines are of growing concern. There is reason to assume that tree-clearance of railroad corridors may have contributed to an increase in number of accidents with moose and roe deer because the cleared areas provide attractive forage and thus may attract wildlife. The objective of my study was to investigate how clearing of trees affected the number of accidents with moose and roe deer. I compared deer-train collision frequencies before and after clearance of the selected railroads and compared these with uncleared control railroads in a BACI (before-after control-impact) approach.

Sometimes relatives have taken me on one side and told me they cannot bear it any more:"Isn't there something you can do to end it all?"More often requests for euthanasia have come from those who are ill. I remember visiting a man with lung cancer. He asked his wife to leave the room. As she closed the door he leaned over and grabbed my arm.

The scope of this investigation is the conditions under which readings of Repulsion (1965), and its depicted mental illness, took place in Sweden during the censorship debates in 1965, and also how the reception was related to narration and subjectivity in the film. The reason for this is the strong reactions to the images of the main character?s inner state, and concerns about negative effects in the public, that were raised. One major concern is how the film articulates discourses through which meanings are produced; that is, how it works as social technology. My thesis is therefore structured around two levels; textual analysis and discourse analysis.

AbstractThe purpose for this study has been to discover and reveal what exactly it is that have made the Wallenberg family so successful in the Swedish business world for more than 150 years. We have narrowed our research by limit it to only find and concern the specific features of the Wallenberg family and not their entire corporate group. There is no research made before regarding this matter, as far as we could see, which is one of the reasons to why we find this study relevant. In order to answer our question we have chosen to use a qualitative approach in which we have interviewed three people. These three people all have deep and thorough insight in the Wallenberg family.

This thesis work resulted in a template for how the thermal spray process can be controlled through robot programs. The robots today and their programs need to be replaced, therefore a new structure which can be matched with the new robot systems is needed. The work is limited to only concern structured programming on the new robots on Thermal Spray Centre (TC) with the programming language Rapid. The basic data for the program was retrieved from interviews with concerned personnel at TC, from studies on process parameters for thermal spray and from existing specifications at Volvo Aero Corporation (VAC). The thesis work briefly describes the process thermal spray and the four methods used at VAC.

This study investigates the planning process of a university library building. The study s major concern is the cooperation of the main participants in this process: librarians, architects and representatives of university colleges and universities. First the authors present the readers with an overview of the litterature concerning this subject. Then follows a presentation of the three case studies. The authors have interviewed representatives of the three different occupational groups at three different library-building projects: Malmö University, Halmstad University College and the department of social- and behavioural studies at Lund University.

The telenursing service deals with offering the public guidance as what to do with their health and illness concern. More specifically this service includes triage, support, advice, education, referral, information and coordination. To conduct telephone advice is a complicated task to perform and put specific demands of the nurse?s communication skills.The purpose of this study was to critically review the impact of telephone counseling focused on context of implementation, perspective, design and clinical relevance by a sample of studies within the field.The critical review focused on inconsistencies in the material. Strengths and weaknesses of the studies were explored, with emphasis on detecting areas of skill gaps.Twelve of thirteen studies were made in the context of telenursing.
