Wind power in Sweden is expanding in response to the government's decision that 49% of Sweden's power should originate from renewable energy sources by the year 2020. Problems with noise and sound emissions related to wind turbines are a constant argument against the wind power expansion and this paper means to examine if vertical axis wind turbines might be a viable alternative to the conventional horizontal design for noise sensitive areas. In order to determine factors like difference in frequency, noise propagation and noise emission level, measurements of both horizontal and vertical axis wind turbines have been completed and the data analyzed with MATLAB. It is shown that there is a difference in how the noise from the two types of turbines propagates due to avariation in the frequency spectra of the emitted sound. It is also shown that vertical axis wind turbines generate a lower sound emission with less intensity inthe lower frequencies..

The purpose of this thesis is to examine if academic libraries market e-journals, and if so how this work is carried out. The ambition is to study what channels and methods the Libraries use, to inform their users that they have access to e-journals. The aim is also to survey if the libraries evaluate the use of the e-journals, and if so how. The objectives of the work are reached by using two main methods, document analysis and qualitative interviews. The study has been performed on three university libraries.

The purpose of this essay is to examine sfi (Swedish for immigrants), which is an ingrational-political tool with objective of teaching immigrants to read and write in Swedish. With the use of critical discourse analysis we examine the discursive practices within sfi. We also examine our methodological and theoretical approaches, and our application of them. Our research questions are as follows:? How are the discursive usage of ?person centered? and ?society centered? expressions being used?? How well does our methodological and theoretical resources work?In our theoretical viewpoint we use ?post colonial theory?, which is a perspective concerned with global power relations seen from a historical perspective.

Wildlife is a valuable and renewable resource that promotes economical, ecological and social values. These values are important for developing and maintaining many rural societies. However, growing ungulate populations have led to increased browsing pressure on valuable forest trees and crops. Previous studies have proposed supplementary feeding and gamefields as potential methods for controlling the ungulate foraging and reducing browsing damage by providing other attractive food resources. However, quantitative estimates of potential biomass production of various gamefield crops and browsing pressure on the surrounding forest have been lacking.

The purpose of the study was to investigate the use and losses of energy in an existing older building. Another purpose was also to look through various options for heating systems with renewable energy in the building. The aim was to reduce the use and losses of energy. The first step was to study the related electricity bills of the building and also perform measurements and calculations of the building envelope and ventilation. The next step was to find out the possible actions for energy saving by performing measurements and calculations.

Background: Balanced scorecard is a relatively new strategy in analysing activities in a company. To carry out a strategy in an organization a successful implementation is very important. Strategy implementations are unique for each organization and to succeed it has to be formulated and implemented with the individual companies particular conditions as starting- point. A problem is that the implementation sometimes is treated as a small detail in the planning process. This problem depends on how the strategic plans is carried out.

In this essay I consider a self-experienced dilemma, and review how I, as a preschool teacher, treat a child with special needs. With the support of literature and theory, I can, with an essay writing approach, reflect and analyze the dilemma. In this way I will examine my practical knowledge and personal experiences of a complex situation. I want to examine whether children with special needs who are included in regular preschool activities, really get the support they need and deserve. Do educators have the conditions and does preschool have sufficient resources to realize this? Do educators have sufficient knowledge of how children with special needs should be responded to? I want to find out how the included children's social development and self-image is shaped by the treatment they receive at the preschool.

Durban, South Africa?s third-largest city is a socially segregated post apartheid society, struggling with high unemployment and AIDS. The city becomes even more complex with a changing climate, creating an influx of people to the city, putting scarce resources under further stress. Warwick Junction, an important transport hub in the centre of Durban, holds a large site of informal trading alongside the formal markets. This informal sector generates large financial flows and provides for a rapidly growing population. The aim of this thesis is to develop an approach that is realistic and relevant to planning and design of an urban context in South Africa.

I intend to examine how teachers interpret the purpose of preschools and the national curriculum and how they handle any problems rising due to the fact that the curriculum is just an instructional document and freely interpreted. Personnel working within the school system have different opinions on how to maintain a functional educational activity. How do they interpret the national curriculum and why? Are there any similarities or differences between different teacher?s views and is it possible to approach this in a constructive way? Is it really possible that personnel working at Swedish preschools are unaware of their purpose or is there another explanation?In this study I have worked according to the qualitative method and have been conducting interviews with the possibility to open follow-up questions with room for interpretation. A total of six people on four different preschools have been interviewed and their answers have been analyzed as a whole.The result from these six interviews shows that there are both differences and similarities in their interpretations of the purpose of the Swedish preschool.

The objectives of this research were to determine whether the natural rattan resources in Sulawesi, Indonesia can cope with the strongly increased harvesting pressure that has occurred over the last centuries. I was furthermore looking for patterns in the rattan population dynamics that might give a hint on how the harvesting system could be improved to ensure a maximum sustainable yield. To answer these questions, I developed an individual-based model to analyse the dynamics of rattan growth in connection with rattan harvests by locals to identify sustainable levels of rattan harvests around villages in Sulawesi, Indonesia. Scenarios with different harvesting intensities were run to compare the change in harvest amount. For a given harvesting pressure, scenarios with a high number of harvesters and a low harvesting frequency had the same effect as scenarios with high harvesting frequencies and a low number of harvesters.

Romanization as a method in the bibliographic environment makes retrieval difficult in many aspects. The object of this thesis is to illustrate the importance and the possibility to include non-Roman script in the records of the library catalogue. The questions at issue are about the consequences of romanization, the technical requirements for implementing non-Roman script, and bibliographical resources that have been developed during the last 20 years. The thesis is based on a literature study and correspondence with people who are familiar with the subject. The thesis points out that Romanization causes information to be distorted in various ways and is inconsistent with the requirements of exactitude in bibliographic control.

This thesis is dealing with the programs of control regarding deceit and quality assurance within the Swedish social insurance administration in Skåne, the years 2002-2005. In 2005 the Swedish National Audit Office released a report regarding the lack of measures towards deceit and fraud, and the lack of quality in the data for decision making within the administration. The questions to be addressed are why the administration does not make up to the demands regarding quality and measures towards deceit that the government and The National Audit Office demands. The main source for data has been interviews with workers within the administration and annual reports from public authorities. To understand and be able to explain the problems within the administration the theory by Michael Lipsky regarding street-level bureaucrats is used.

Nyttjandet av motorfordon i allmänhet och snöskotrar i synnerhet har ökat kraftigt i naturen. Snöskotern har sedan introduktionen i Sverige, i mitten av 1960-talet, brett ut sig över hela Norrland. Många människor kombinerar nuförtiden intresset för friluftsliv med snöskoteråkning. Fordonet används emellertid inte enbart för rekreation utan är också ett arbetsredskap. Det är dock som fritidsaktivitet snöskotern rönt mest uppmärksamhet.

The project was intended to produce a brush simulation plugin to the image processing program GIMP which would use a 6DOF drawing tablet for user input.Too ambitious goals coupled with compability issues between the resources used resulted in that no meaningful software was produced. Experience was however obtained, and this paper is intended to give an overview of relevant concepts for- and the process ofcreating a brush simulation..

The use of Internet by children and teenagers has become a special field of interest. Certain risks are associated with young peoples use of this media and national and international measures have been taken to assess and counter these risks.Library and informationscience have approached the subject of risks by looking at different software´s, so called Internet filters, that is used to control and censor the access to Internet based resources. In the USA, where public services and institutions that provide Internet resources to children and youth have started to require censorship of the Internet, a debate has arisen concerning the use of so called Internet filters.The theoretical basis of this master´s thesis is related to the conception of risk, gender and childhood. The focus of the paper lies on young peoples use of information and communication technology (ICT) and how risks associated with young peoples use of the Internet is constructed by different parties involved in supplying Internet resources. By means of a case study at a primary school in Skåne and at the company Netscan in Malmö.
