The dependency of continuous electricity supply is high in the Swedish society today, at the same time no one is willing to pay for a too costly or over dimensioned power distribution system. The owners of the distribution systems are the ones responsible for this balance act of maintaining a high quality of electricity delivery to customers at a reasonable cost.In this master thesis a limited part of the primary distribution system (10 kV), owned by Mälarenergi Elnät AB and located in the city centre of Västerås, was chosen for a deeper analysis of its reliability. Its ability to handle outages of system components (N-1 and N-2 contingency analysis) was investigated to find out potential weak spots and parts of the grid that showed signs of being overdimensioned.The results of the performed simulations showed that in 74 % of the studied N-1 contingencies cases, consisting of outages of a bus bar in a distribution substation, the system could handle this without causing outages in other parts of the grid. For the N-2 contingencies 61 % passed the test. It was also found that one of the two included high voltage substations could alone supply the investigated part of the grid.

Sustainability reporting in Sweden is a voluntary disclosure action for non-governmental companies. Since 2009 all state-owned companies must however publish a sustainability report according to GRI guidelines and with independent assurance statement. Three different sustainability reporting methods are primarily used: (1) Separate Sustainability Report, (2) Sustainability Report included in the Directors? Report, and (3) Sustainability Report forming part of the Printed Annual Report. The aim of this paper is to explore why some companies choose to publish a sustainability report and identify the motivational factors behind this decision, as well as attain an understanding for companies? choice of reporting method.

This bachelor?s thesis studies Carl Str?mbergs ?ppeltr?dg?rd, a private garden consisting of a large number of apple trees and varieties. The garden is located outside ?rebro, in N?rke, and is owned by a unit owner association whose goal is to preserve and determine the varieties. Through interviews, articles, site visits and documents from Carl Str?mberg, the purpose have been to get an understanding of who Carl Str?mberg was, how he collected the apple varieties and how that process was affected by the climate amongst apple growing and pomology during that time.

A major issue that has been a subject for quite some time is whether there will be a scarcity of metals in the bedrock in the future and whether or not we might end up with a problem similar to that of the big oil crisis in the mid-seventies. Following the oil crisis many oil companies started up with risk management to control future risks. This work presents how Swedish mining companies work with risk management to handle risks that might come up in the future due to metal scarceness. How Swedish mining companies look at the possible metal scarceness and if they use risk management in their decision-making process is studied. By doing interviews with Swedish owned mining companies it was found that the mining companies did not see the future metal scarcity as a risk, even though 2/3 of the companies acknowledged the scarceness to be a reality.

AbstractThe purpose of my study is to compare Sten Rydhs wiew of learning disabilities in mathematics and his education with current literature and research. I want to explore whether the education of ?Mattesmedjan?*, influenced by the Suzuki method, can be the solution for the students with maths problems. ?Mattesmedjan? is a privately-owned school of maths.

The female labour is still a rather unexploited resource in many parts of the world. Unleashing women?s potential, giving them the possibility to start their own enterprises would increase the economic growth. Not only does women's entrepreneurship foster greater equality in the world but it also creates a more versatile economy. Sweden is considered to be one of the most equal countries in the world; still, entrepreneurship is an area with sharp gender differences, especially in some industries.

My essay is on the subject of teachers work environment with focus on noise and communication. In the essay questions are raised on how a teacher can influence his or hers noisy work environment. A school is a large work place with many employees and is owned and administered by the county municipality which is an even bigger workplace. How big an acting space does a teacher have in such a large organization?My methods of research on these questions have been to conduct interviews and analyzing documentation from The Swedish Work Environment Authority.

The National Property Board (SFV) has been appointed by the Swedish government to administer all property of cultural value owned by the Swedes collectively. The commission includes maintaining the soul and character of each individual building, to adapt these buildings to present needs and requirements, and furthermore making them available to the public. The return on equity demanded by the government is based on the CAPM used within the real estate industry. The theoretical assumption that organizations are either function-driven or pay-driven will serve as a starting point, after which SFV will be defined as a function-driven organization with a pay-formed management control system. This paper aims to examine how applying a pay-formed management control system will affect a function-driven organization.

Previously when I have made proposals for privately owned gardens, I have found it difficult to find strong, extensive designs and to work with room and space. Since this is the field within which I am going to work in the future I feel that I need more experience, reference material and ideas on how I, in an early stage of the working process, can work with and consider room and space. The aim of this project has therefore been to procure experience, reference material and ideas for design of a garden in relation to space. To procure experience and reference material I have, during the fall of 2008, made two incredible study tours to France and to Japan. I have interviewed the landscaping architect Maria Arborgh and studied literature. I have also used a garden outside of Gothenburg in which I have been able to try out different thoughts and ideas regarding shape that have appeared during the course of my work. My conclusions about landscaping are that you should first find the different functions in the garden. The next step is to find an overall theme or shape, use a small number of materials, build a room with sealing, walls and portals with the help of vertical elements e.g.

The City of Stockholm has decided to invest in renewable energy and especially in photovoltaics. The objective of this thesis is to investigate the photovoltaic potential on roof areas that the city possesses and to further investigate some buildings of the Property Management Department. The thesis also compares some existing photovoltaic plants with the solar irradiance map which shows available roof area on each building in Stockholm. The report ends with a literature study about the climate impact and greenhouse gas emissions of photovoltaic.The total available roof area suitable for photovoltaic plants is estimated to 700 000 m2, with a potential electricity production of 110 GWh per year. This corresponds to 17 % of the City of Stockholm?s yearly electricity consumption.

Introduction: Increased savings in funds has enforced the importance of the institutions. During the last 25 years they have augmented their ownership from 20 to 85 % of the Swedish stock exchange. Thereby the ownership becomes more and more financial, meaning that the return is the most crucial. In an article in Dagens Nyheter the president of the Swedish Shareholders Association and the president of Metall object to the institutional passivity which they consider being an important problem. Purpose: The purpose of this essay is to put the institutional passivity in perspective.

The objective of this study was to contribute with suggestions of nature preservation managements of selected forest objects of high nature values managed by the Swedish state-owned forest company Sveaskog. Many forests with high natural potential are relatively rare today due to modern forestry, where wood production is the main purpose. Sveaskog?s policy is to consider and to priority nature conservation on valuable objects. This assessment includes objects that in the future may develop into nature reserves.

Stjärnägg is a sales organization operating on the Swedish eggmarket, owned by nine Swedish packing companies. Those nine packing companies are not just owners of the sales organization, but at the same time competitors since they compete in the market when they do not sell the eggs through Stjärnägg.The purpose of this thesis is to evaluate the sales organization from a supplier and owner perspective. To answer the purpose of this study, qualitative interviews have been conducted with the owners of the egg packers. This has been done in order to get as fair picture of the sales organization as possible. From the answers of the interviews, a compilation has been made to be able to give Stjärnägg concrete proposals of improvements in the organization.

The objective of this report was to analyse and compare vulnerability and preparation in Swedish municipal drinking water production, in case the commonly used water sources were inoperative. Methods used were a questionnaire and a less extensive study of regulations for water protection areas. The questionnaire was answered by 41 Swedish municipalities. A handful of them were companies co-owned by a few municipalities. Only one out of four municipalities had source protection areas to all their water sources and for many sources the protection was not satisfactory.
