In order to make take-off and landing procedures possible at an airport, an organized allo- cation of slots is necessary. How these slots shall be distributed among airlines is, at pre- sent, governed by the European Parliament and Council Regulation (EEC) No 95/93 of 18 Janu- ary 1993 on common rules for the allocation of slots at Community airports. It is important for the air- lines to be allocated a beneficial slot. Hence it is of great interest for the airlines to ex- change and transfer the allocated times among themselves, a form of secondary market. Whether such practices are allowed or not is not regulated by specific detail in the regula- tion, which leads to legal uncertainty.

This paper is a literature review that examines how good mental calculation skills benefit pupils, which could work as a valuable learning tool for future teachers. The study addresses four key questions: ?What are the advantages of proficient mental calculations??, ?What strategies exist for mental calculation skills??, ?How can teachers accommodate their teaching to develop pupils? mental calculation skills?? and ?What has arithmetic looked like in different eras and what algorithms have been used??. Through literature searches in search engines, scientific articles were found, which formed the basis for the result segment. This was divided into two parts: A historical and a didactic overview.

7 % of children in preschool have some sort of language disorder. How should preschool teachers best help these children?

Northeast Stockholm is a region developing fast. There is already a great need for new transport solutions for the people commuting to the city, since long queues slow down car traffic and the local railway, Roslagsbanan, needs to be upgraded to attract more travelers. The competitive advantage of rail?traffic over the car when it comes to greenhouse gases and air pollutants is another reason to develop Roslagsbanan.This report investigates the differences between car and train to create a basis for a proposed expansion of Roslagsbanan. Once the proposal is presented, costs, emissions reductions and public benefits are analyzed.

The energy sector of modern time is currently faced with several challenges. These are both production oriented and environmental oriented in nature. The energy of the future is intended to support an increasing demand while at the same time reduce its environmental affection.

In today's fast-paced, intense and complex media environment, it is hard for non-profit charity organizations to reach out and get their messages heard.In this study we examine whether the theories of advertising signaling also applies for charities. Past studies of the signaling theories indicates that higher perceived advertising expense leads to more positive effects on purchase behavior and brand perceptions. However, we believe that this does not apply for a charity organization. We argue that since charitable organizations have a fundamentally different mission than commercial companies, they will need different ways to signal quality and credibility, and therefore the common signal-theories will not hold for these organizations.To test our hypotheses, we conducted two surveys where the respondents saw one of five versions of the same ad for a well-known Swedish charity organization, or one of two ads for a commercial corporation. The ads had been manipulated to simulate different levels of perceived cost.Our results shows that perceived ad cost only affects attitude towards the ad if a charity was the sender, whereas perceived ad cost affects intentions, attitudes and credibility if a commercial corporation was the sender.

Background: A great part of all projects within Swedish industry are conducted in a multiprojectenvironment, which means that several projects are performed simultaneously. The research within the field of project management is though focused on single projects. Projects are highly dependent on the context in which they are conducted, although the organization of the multiprojectenvironment is only partly explored. Furthermore is the research within the project management highly concentrated on standardization of the project work. The question is whether this implies to the basic advantages with the project-oriented organization, which is flexibility and creativity? Purpose: To describe and obtain an understanding for the multiprojectenvironment regarding management control and organization.

The doctrine of traditio is the main rule for the buyer?s protection against the sellers?s creditors in the Swedish legal system. This means that the buyer have to take physical possession of the property in order to be protected against the sellers?s creditors if the seller becomes bankruptcy or is hit by an execution. If instead the doctrine of consensus applied the buyer is protected as soon as a valid contract is formed.

Mediation of fiction has always been one of the main tasks of the public library. The focus on information technology is often seen as a threat and competitor to this task. But technology can also offer new ways to mediate fiction, and the aim of this thesis is to examine how library websites and blogs can be used for this purpose. The research questions are:? What forms of fiction mediating material exist on library websites and blogs?? How is the fiction mediating material presented?? Are there any differences between the fiction mediating working methods on websites and blogs compared with those in physical libraries?The thesis is based on a qualitative content analysis of eight Swedish public library websites and three blogs, and on a theoretical frame work including literature and research on mediation of fiction, library websites and blogs, web design and usability.

This thesis describes possibilities for Metso Paper to lower their costs of spray pipes for their pulp wash press TRPE, with maintained good functionality and quality.Information that can be used by competitors has been censored in this version of the essay.To find solutions, alternative suppliers have been contacted and asked to quote. There has also been a new spray pipe designed. The manufacturing costs of the new design have been calculated.The thesis also contains a concept generation of an alternative product to the spray pipes in installations where a high pressure washer is used.To be able to ask other manufacturers of spray pipes to quote, a demand specification based on the currently used spray pipe was made. This was then sent to two alternative suppliers.An investigation of earlier used spray pipes, and the currently used, shows that the nozzles are a big part of the total costs of the spray pipes. To attempt to reduce the nozzles high cost an concept generation was made to find the best solution for a new design.There was a request that it should be possible to change the internal brushes in the spray pipe without cutting and welding.
