In a multi-year project at Swerea Swecast AB studies on influence of dissolved gas on inclusions have been made. The knowledge about these parameters could be used to increase the quality of the final steel casting. The purpose of this thesis was to closer examine the impact of the oxygen level on inclusions.The questions asked were:? What was the amount of inclusions at different levels of oxygen?? What was the size of these inclusions at different levels of oxygen?? What does the inclusions consist of at different levels of oxygen?This was studied by measuring and sampling, sample preparation and microscopic analysis using an optical microscope and a scanning electron microscope (SEM). Measurements and sampling was performed at Smålands Stålgjuteri AB in Eksjö and at Swerea Swecast AB in Jönköping.

There exist several known methods for calculation of radio coverage for ground-based systems. As far as we know there are no equivalent methods for the case of flying platforms when the altitudes and speeds are significantly different to those of ground-based systems. This thesis describes the theoretical concepts behind calculations of radio coverage for flying platforms. An investigation is made to sort out what is important and possible to employ in a model for simulations. A method is described and implemented in a program for evaluation of flying radio systems.

The aim of the thesis is to explore how the human subject is depicted in contemporary posthumancinema and how these films effect our comprehension of human subjectivity. The object of analysis isJames Cameron?s Avatar (2009) and the method of analysis is cybernetic and intermedial. The conclusionis that Avatar is a film that depicts a posthuman network society where existence and subjectivity in a greatvariety of forms is possible. The film presents posthuman subjects in symbiosis with avatars, terminals,extensions and prothesis.

The study aims to demonstrate the significance of educators lived experiences of stimulating children's physical development. It has been noted that children are occupying themselves with more and more sedentary activities, which may lead to that they do not develop motor skills at the pace expected. To understand educators lived experiences from a phenomenological hermeneutic perspective empirical relevance has been collected through narrative interviews. The results shows that educators find it difficult to understand the Curriculum goals for motor activity and that the desire to stimulate motor development is great, but the realization is conspicuous by its absence. The discussion highlights educator?s commitment and motivation and the importance of being a reflecting practitioner..

The aim of this essay is to study how cultures are presented in English textbooks for A-level students in Sweden. The aim is divided into three research questions, what does culture in English teaching mean, how is the English-speaking world presented in the textbooks and is the image that is presented stereotyped or does it try to challenge it? The study comprises of four textbooks from 1998-2008. The theoretical frame used in the essay is Edward Said?s Orientalism.

Sweden's drinking water quality is considered to be high partly due to a high quality of the raw water and a well developed sewage infrastructure. Despite this, there is water contamination that could be prevented by installation of a sophisticated early warning system. Some of the major players in the production of drinking water have already invested in different types of early warning systems to ensure drinking water of high quality. There are various forms of early warning systems where automatic monitoring of E. Coli is an interesting alternative.

The Swedish armed forces are facing a change, a change in both organization and profession. From a conscript military service system, the Swedish Armed Forces has changed to having full-time contracted soldiers. Conscript military service has a history of over a hundred years; it was introduced in 1901 and has survived two world wars and the Cold War.The Swedish armed forces have changed to have contracted soldiers. My reflection is whether the armed forces really have had time for this changes that the new professionalization has meant. Today the Swedish armed forces consists of contracted soldiers, soldiers who are employed full time and costs the armed forces a lot of money.

Abstract Our society is becoming increasingly multicultural and so are our schools. This study raises the question of how teachers are working to promote multi-culture and how they can create an understanding of the diversity in the classroom. One way is to use the literature. Literature is already well integrated by many teachers and widely used by pupils. By making use of literature related to multi-culture, pupils can get a deeper understanding of our society.

The idea to create authentic learning situations where students are highly integrated made me want to try to develop a new method in the course Restaurant and Catering B MAKU 1208 (another field practicing cuisine). In my quest to do just the practical part as rewarding, stimulating and efficient as possible for the student, I planned for a training model with   focus on group interaction.The implementation of the model for learning was to strengthen students confidence both in themselves and in each other, stimulated to greater cooperation and it has also provided an incentive to the student's own development but not least, a growing self-confidence for many students. Several have also had an increased sense of knowing something, to have something to contribute and that their labour input actually was needed. While highlighting that further education to seek knowledge strengthens the individual's skills and consolidates and increases deeper knowledge in the professional field.In conclusion, training should be done in both individual and group basis for optimal learning process..

The system tungsten-oxygen has potential of being suitable for decorative coatings since ceramic coatings are often hard and wear resistant, and since modulations in oxygen content or incorporation of small ions could give bright colours. The aim of this report was to investigate the relationship between process parameters and  the properties of the films, with the wear resistance being of special interest.Samples with tungsten to oxygen ratios in the range of 100:0 to 25:75 at% were made using reactive sputter deposition, either with constant gas flow, or gas flow controlled by optical emission of the plasma. The hysteresis of the system, which means that a certain gas flow will cause different pressure and/or target voltage depending on in what way the flow is reached, makes it interesting to control the process where the system makes the steep change from metallic tungsten to ceramic tungsten oxide. This is difficult and thus requires precise control equipment.The samples were analysed using X-ray diffraction, X-ray photoelectron spectroscopy and an empirical wear test suitable for small components like cell phone cover for example, in order to characterize the structure, composition and wear resistance of the coatings. The results could be divided into three groups: (I) tungsten-like, with very low oxygen content; (II) mixed phase and (III) tungsten oxide like, with oxygen content close to 75 at%.

Abstract Author: Annika Sjögren ArvidsonTitle: The reflective leadership role in social service organizations Supervisor: Anders GiertzAssessor: Jan Petersson  I have studied the leadership role of unit managers in social service organizations and their relationship to the concept of reflective approach. I started from a curiosity about how and if unit managers within social services use the concept reflective approach in their leadership role, and how their organizations look upon this and what the consequences are. If in the long term, this affects the individual receiving assistance. All the interviewed persons come from different places, services and organizations. The study is qualitative, with a number of interviews conducted with unit managers.

In this thesis the core of the nursing professional skill will be portrayed through the opportunities of the essay writing. Thus the tacit knowledge, which is at the verge of erosion in a zeitgeist where medical care shall be cost-efficient and where development is mainly based on scientific research, will be articulated. Scientific articulation of knowledge has gained increasing importance on the expense of the practical knowledge. Healthcare professional skill requires a refind ability of judgment, which absorbs its nourishment from both scientific knowledge and the proven proficiency expertise.Professional skill expresses itselfs through action, especially through the acting in unexpected incident. Experience is developed into knowledge through reflection.

The purpose of this study was to find out what pedagogues in preschool think when it comes to children?s influence and how they do to give the children opportunity to express their thoughts and point of views and thereby influence their situation.The literature review treats the conception of the competent child and shows that having child perspective is important in meeting children. The literature review implies that participation and influence means sensitivity to children?s expressions and that pedagogues lets these expressions influence the activities in preschool. It is not about children always getting their ways, but that they are respected and are given space to think freely.Searching for pedagogues? thoughts on children?s influence and how they do for giving it, I interviewed six persons, working at six different preschools.

Denna undersökning syftar till att undersöka nationella skillnader i moralutveckling och innehåll i moraliskt resonemang. Studien omfattar 445 svenska och 148 amerikanska ungdomar i åldern 14-19 år. De svenska fpp är hämtade från högstadium och gymnasium i Stockholmsområdet, och de amerikanska från två katolska privatskolor i New York. Dessa tog del av ett moralfrågeformulär av Gibbs (Gibbs & Widaman, 1982; Socio-moral Reflection Measure; SRM) som är en reviderad version av Kohlbergs intervjumetod för bedömning av en individs moralutveckling och kvalitativa, moraliska synsätt i frågor rörande moral. Vid analysen förelåg inga nationella skillnader i moralutvecklingsnivå.

Within literature, politics and science, there is a claim that ?tree avenues are important?. But the question and the goal for this essay are to explore the pretext to how and why. Planting tree avenues is a 4000 year old tradition and they are a common element in the Swedish and Scanian landscape since the 18th century. They were first mainly planted by aristocratic land-owners or on their initiative, but since the 19th century also by farmers.
