Media is a big part of our society and plays a major role in the socialization of young people. It sets the agenda for what?s important and newsworthy. In media coverage today crime and violence occupies a lot of the space. The evening press like Aftonbladet, Expressen and GT often use crime to sell their papers.

This is an essay concerning the density of the city. An increasing amount of today?s cities have a shortage of space available for the erection of new buildings and settlements, especially in areas close to the city-centre. New buildings and settlements are therefore often found in the outskirts of the city, resulting in long distances between work and living for many people. These long distances are a waste of limited resources and are inconsistent with the vision of the sustainable city.The challenge for the future is to insert new buildings and settlements in the existing city-structure and in this way reduce the distances between different city-functions.The density of the city can be increased in two different ways; by inserting new buildings between existing ones or by extension existing buildings, for example by an additional floor.

The use of mindfulness in healthcare is increasing in Sweden. A so-called secular form of mindfulness is also increasing within mediated contemporary psychology and is used in many areas such as schools, workplaces and when giving birth. The method originates from Buddhism and is much more complex than the form of mindfulness marketed in Sweden today. The religious heritage of mindfulness is interesting to study in such a secular society as Sweden, where the material for this study is found. The aim of this study is therefore to investigate whether mindfulness still is a form of religious coping or if it has become completely secularized, and thus free of its religious origin.

This master thesis comprises analysis and dimensioning of a keyed joint between a generator axis and a hub with aid from the FEM-software ANSYS Workbench 13.0.The generator axis is a part of a hydroelectric power station that generates electricity with a reactions turbine, a Kaplan turbine. The existing keyway consists of one parallel key with the width 90 mm and height 45 mm. Due to a planned increase of the power of the generated power with 32 % a design study was needed to see if the keyed joint would be suitable for the extra force. Because of the fact that the axis diameter is bigger than the standards covers/recommends a the keyway had to be re-dimensioned. In an earlier assignment from Skellefteå Kraft AB to Sweco Energuide the keyway was planned to be properly dimensioned, but no final solution was approved.During this master thesis a number of different numerical tests were made.

Problem discussion: That empowerment and autonomy can lead to desirable effects on employees is clear. Previous research has found correlations between empowerment and e.g. motivation, job satisfaction, productivity, loyalty and commitment. However, a control problem arises when employees have more freedom in decision-making which could potentially lead to undesirable outcomes. It thus becomes a type of dilemma for management and managers where you have to try to balance a restrictive use of the control system (to maintain control) and an enabling use (to promote empowerment).Purpose: The purpose of this study is therefore to identify how a company can use its control system in order to achieve empowerment while maintaining acceptable levels of control.

The town square is an important public space and is often described as the city´s living room. By creating a lively city center a sense of security is developed among the citizens which makes them wanting to use the town square regardless the time of the day. One important meeting point in Gävle is the centrally located Stortorget, sited between Drottninggatan and Nygatan. The town square went through an extensive renovation followed by both positive and negative reactions among the City´s inhabitants.  The aim with the study was to investigate the main walking paths and meeting points as a planning support to Gävle Municipality in their work with a new city plan. By studying the pedestrian movement patterns at Stortorget, Nygatan and Drottninggatan, the main walking paths and meeting points during all hours of the day was obtained.

Native spider silk is an attractive lightweight natural polymeric material with a unique combination of strength, extendibility and flexibility. Synthetic, recombinant spider silk is an attractive biomaterial with several possible fields of application. When a foreign material is introduced to blood, this can for example cause unwanted coagulation and complement activation. The aim of this study was to investigate if coatings of heparin or albumin could improve the blood compatibility of films of recombinant spider silk and to develop an initial method to do so. Hypothetically, objects like pacemakers, stents and dental implants could be covered with spider silk films of high blood compatibility to reduce potentially harmful foreign body reactions caused by the immune defense. Increased blood compatibility would likely lead to improvements for both the individual patients and the society thanks to reduced load on healthcare institutions. Our objective was to assess the blood compatibility of both functionalized and non-functionalized recombinant spider silk by evaluating coagulation and activation of the complement system of the immune defense. Coagulation was evaluated visually on glass slides and complement activation was analyzed by measuring the concentration of the complement system mediator C3a in blood samples that had been exposed to the different materials. This study introduces a non-toxic and easy performed method of improving the blood compatibility of recombinant spider silk films by adding a heparin coating. Heparin coated surfaces had statistically significantly higher blood compatibility than uncoated surfaces. The effects of albumin coating of films were less clear compared to the results of heparin coated films. Complement activation could not be evaluated because of high activation in all samples prior contact with the materials that were included in the study..

The aim of this study was to examine self-harming women?s own experiences. To try and raise understanding and awareness about how they themselves create their identity and meaning round the self-harming behaviour. Our three questions were; how do the young women conceive society?s reactions on their self-harming behaviour? Do the young women express an imposed or self-elected alienation? If so, in what way? In what way do the young self-harming women construe their own identity in relation to the self-harming behaviour?We have used a narrative approach when we have examined the blogs as life stories in the sense that all our lives and everything in them is a story by definition.

The Swedish Prime Minister, Tage Erlander, made a speech on the 22 of August 1961 in which he dismissed speculation that Sweden was seeking to abandon its neutral stance and non-alignment in foreign policy with a view to requesting membership of the European Economic Community. The reason was that the EEC was supposed to have a political part where a connection with NATO should have existed. This speech led to a domestic discussion which has been called the most intense debate of foreign affairs in recent history. The purpose of this paper is to analyse the reactions of the other parliamentary parties to Erlander?s speech.

To be educated in global climate issues can be challenging for pupils. This may contribute to anxiety and feelings of helplessness. Global climate change may also be a challenge for educators to convey to young learners, f-3. Educators can experience various problems when it comes to teaching about climate issues. The subject of climate change is a broad and complex area, according to the studied material in our thesis.

Fast pyrolysis is a method for converting biomass into three energy rich products: char, gas and bio-oil, where the latter is most interesting.  Pyrolysis is an endothermic process where biomass is heated in an anaerobic environment and, with the right operating conditions, up to 80 %wt bio-oil can be extracted. Key parameters for fast pyrolysis are: stable reactor temperature (~500°C), short residue time for gas in the reactor (<2 s) and a very high heating rate for the biomass. Today there are several different process solutions for fast pyrolysis, where fluidized beds and rotating cones are most developed. Bio-oil has compared to fossil oil: lower heating value, low pH and also polymerizes with time. Because of this upgrading is desirable for increasing competitiveness.

Forest enterprises have always searched for ways to improve efficiency. For the past few years there has been an emphasis on stock-keeping levels. Increased demand for fresh round timber and the need to decrease the amount of tied-up capital has made the forest industry reduce its inventory levels. This has brought on a higher demand on the timber supply from the forest management districts concerning both delivery in time and assortment output. As a result, the flow of timber has fluctuated a lot with serious consequence for the timber supply during 1994.

An excessive input of nutrients to lakes and other water bodies has created a problem with eutrophication in Sweden. Untreated, or partially treated, domestic sewage is a major source for discharge of phosphorus (P), which is the nutrient most frequently responsible for eutrophication of most fresh waters and the Baltic Sea. The waste water can be cleaned by filter materials, which have a high P-retention ability and which after saturation may be used as fertilizers. Four potentially suitable filter materials were tested in batch- and column experiments in this study. In the batch experiments, the following materials were shaken with waste water in time series ranging from 5 seconds to 60 minutes: coarse (1-4 mm) and fine (0-2 mm) Polonite® (heated bedrock from Poland); Filtralite® (light expanded clay aggregates with limestone added before burning); water cooled blast furnace slag (BF-slag) and BF-slag mixed with 10% burned limestone.
