AbstractAt Saltvikens copperindustry, which is located in the municipality of Oskarshamn, copper was refined from sulphiteore some hundred years ago. The ore underwent several steps in the process before the final product was received. These steps all had an influence on the environment through discharge of heavy metals. The area where the copper industry was located is today considered to be of specific national interest due to its valuable nature and cultural values, as well as its value for recreational outdoor activities. Therefore, it is important to determine the present level of contamination and if any transport of contaminants have occurred, and to identify the risks that are associated with the site both at present and in a longer time perspective.Thirtynine soil samples and 16 sediment samples have been analyzed.

The purpose of this thesis was to investigate the need of working instructions in Derome Träteknik ?s industrial house-building factories. Furthermore we wanted to determine an appropriate way for developing working instructions adapted to the conditions in a certain production environment. In the construction industry today prefabricated building elements are frequently used. With this come repetitive work tasks that need to be carefully planned.

This study is about how a swedish brand within the food industry that experiences a crisis following a product failure. It focuses on three areas following the crisis and these are crisis management, recovery strategies and brand management. This study seeks to explain how these areas interact in relation to massive exposure to mass media and how they interact restore the brand's potential loss of reputation. This study was conducted as a case study with a deductive and qualitative approach. The data gathered to this study was mainly based on newspaper articles and complemented with semi-structured interviews with twelve local retailers of the brand..

During the last decennium climate issues have become more and more important. Many steps towards an adaption of efficient energy supply systems have been taken all around the world. These steps have been created to ensure the next generation?s energy demand. In EU and Sweden objectives have been set to ensure that the energy consumption decreases by 20% year 2020 and by 50% year 2050 compared with the energy consumption levels of year 1995.

This report present the design and manufacturing of a wide-band driver amplifier placed in radar module for airborne applications. The major goals for the amplifier were a high efficiency and to deliver a predefined output power. To reach the second goal an additional preamplifier had to be constructed. The amplifiers were constructed in three steps: Design and Layout in the software Microwave Office, Mounting components and Verification. The driver amplifier was decided to be a push pull configuration consisting of two parallel transistors biased in class AB.

Landfill leachate contains a variety of contaminants and is created when rainwater percolates the landfill. For landfill management the leachate is the main issue that can cause problems to the environment. At the landfill of Fläskebo, Renova AB treats the leachate in a local treatment plant. The treatment consists of a chemical treatment step with chemical precipitation, flocculation, sedimentation and filtration, and a final step with a carbon and peat filter. Renova has to ensure that the condition of the leachate reaches the regulation set for the landfill before it is released to the recipient.

The beta value is frequently described in theory and is a well known factor to quantify the systematic risk in shares through the CAPM model. Initially, this study describes the advantages and difficulties with the estimating process and the problematic nature of the assumptions and descisons included in published beta values.An alternative method, Bottom-up beta, to estimate the beta value that probably has not been tested under Swedish circumstances is applied. The problems and decisions that have to be made to derive an alternative value are studied in detail through six separate steps. I have chosen nine companies at the Stockholm Stock Exchange where this method is used. The result showed that the systematic risk were higher at five shares and lower at four, compared to the published values.Finally there is a discussion about the practise, usefulness and opinions concerning how to estimate and interpret the beta value to determine the expected return..

Today there are commercially available databases with active features, i.e. active mechanisms are available for development of information systems. But the usage of active mechanisms is low in practice. This is due to the insufficient methodological support in analysis and design for developing ECA rule based software. It has been proposed that one of the most suitable ways to tackle this problem is not to develop new methods but to extend existing methodologies.In this thesis an extension of the Object Modeling Technique (OMT) is developed, called OMT-A, which is able to model active rules.

The aim with this essay is to look into what literature has been published in 2006 and 2007 for boys between the ages of twelve and sixteen in order to analyse six of the titles. Our two main questions are as follows:?How is the teenage boy depicted in six of these books? - To what extent is the teenage boy depicted in a gender stereotypical way?.We chose the titles for analysis based on our mapping of the published literature and took into account the authors? gender and age as well as the main themes of the books. As theoretical base for our analysis we used Marias Nikolajeva?s table of gender stereotypes in literature.

Over the last decade the conversation on entrepreneurship has been both worldwide and intense. In Sweden, as in many other countries, this conversation has also concerned women?s entrepreneurship. Parallel with this conversation has been the debate on women in leading position in large corporations. This thesis aims to find out why and how women use entrepreneurship to handle existing conditions in life (such as the hardship of combining a traditional career with a traditional family life) and to create new conditions that suit them better.

The purpose of this paper was to examine how people experience the practice of Cannabis in daily life. The study was based on interviews with five individuals who have experience with cannabis use. They do not represent a bigger population only themselves. We chose these particular individuals because all of them began using cannabis at a young age- everyone before they were twenty. But they have been using cannabis because of different reasons.

This paper aim to present a model for evaluating what we choose to call HTML-frameworks, a framework that contains a set of CSS layouts and occasionally JavaScript support, based on the characteristics of the software quality standard ISO/IEC 9126-1. The methods used to produce this model is based on a field study that involved making a web portal with the help of a HTML-framework, some relevant literature and an analysis of the framework based on the characteristics of the ISO/IEC 9126-1 standard. The result was a model based on twelve different characteristics; functionality, web browser compatibility, collaborative skills, user-friendliness, documentation, visuals, graphic layout, performance, activity, professional support, replaceability and license. This model should be viewed upon as a suggestion to what a model for choosing HTML-framework could look like, because we haven?t had the time to test it in a real situation, so further studies are needed, and we believe there could be improvements made in the objectivity of the assessments of the characteristics..

Detta examensarbete är utfört i samarbete med dumpertillverkaren Volvo CE i Braås. Då dumpern framförs i hård terräng är det nedersta insteget fäst i två stålvajrar vilket gör det flexibelt. Då flexibiliteten in mot maskinen idag är större än företaget önskar undersöks det i detta arbete alternativ till dagens lösning. Detta görs med hjälp av ingenjörsverktyget ?Eight Steps to Getting Design Right? vilket är en produktutvecklingsmetod som gör det lätt för läsaren att följa utvecklingen från idé till färdig produkt.

Invoxicated is an interactive play sculpture where children can explore the wonderful and playful opportunities of sound. Talk into one end of the sculpture, and the sound will travel through the sculpture and come out in the other end. On its way, the sound gets distorted by a number of sound effects. By bending the sculpture?s body, and pressing the sculpture?s buttons, the sound effects gets altered in real time.

Contents:The evolution of today?s computer influenced society has taken giant steps towards virtual reality, game addictions and the possibility of not having to meet the people we communicate with. What is a reality today?To give a more concrete image of our question we?ve chosen the online game World of Warcraft as an example and to describe our connection to an alternative reality. We have performed different investigations, interviewed both gamers and non gamers, all this to give us the opportunity to see if the term reality has started to change in a direction that will allow us to call this alternative world a reality, or if it?s just a world wide phenomena of for example gaming addiction.
