In this thesis, a transparent model of the human head has been constructed which was filled with a substance that represented the brain. This model was later crash tested. This was done in order to examine how a transparent model of the human head can be constructed to generate accurate data from crash tests. It was also done in order to examine how impacts on the front of the head can deform the rear of the brain. When a head is decelerating, the brain moves forward inside the skull and may hit the front of the skull.

In this project the author made an attempt to, in a short film, visualizean experience of the organic materials that our bodies consist ofand what becomes of it when we die. The intention was to dissect thismatter, break it down to see it in a simpler form and to explore ourrelationship to it, being part of a constant exchange between organicmaterials and having so much power over the environment and otherliving animals. At the very start, the idea was to deal with the relationshipdifferent people have with their bodies. Later in the process, a decisionwas made that the product would be communicating the author?sown experiences of the body materials after studying it and trying torecreate fragments and feelings of them.

Interactive media is constantly increasing in our surroundings and with the innovation of touch-screens, two-way communication with screens has become part of our daily life. Still, this well known way of process information is not often seen in the in-store environment of grocery retailing. Here, interactive media is an unestablished field where empirical studies are invisible within the academic world. The lack of knowledge in which effect interactive digital signage has is one of the barriers of investing in this marketing solution in-store. The main purpose of this study is to examine and describe the effects of interactive digital signage at shelf within grocery retailing.

At a manufacturing company, due to the competition the price is reducedtowards the manufacturing cost. Therefore it is important to maintain control ofones costs and keep calculations up-to-date.This thesis deals with cost accounting at a aluminium-processing company. The report focuses on calculating machine cost per hour since the manufacturing costs are the major part of the total product cost.Managers on the company believe that the costs they use in calculations todayneither is up-to-date nor advantageous in a market aspect and due to that their calculations need to be revised. The machines cost per hour is a major part in the manufacturing calculation. The company wants to provide a competitive price that also covers their costs.

AbstractThe purpose of this essay is to investigate the views Swedish elementary school teachers produce on the subject of ethics. The teachers? thoughts on selection among ethical notions is described and also how these notions are assessed. The essay proceeds from the central content and the knowledge requirement in the syllabus of religious knowledge.The empirical survey is based on qualitative scientific interviews with four teachers employed in grades 4-6 at different schools.The teachers find ethics in its current state of the syllabus hard to define and they find encounters with parents and pupils difficult in their tasks. The selection of ethics is decided by previously planned basic values education or from conflicts erupting during schools hours.

To many of us blogging is a natural part of our everyday life. Bloggers dedicate hours to writing in blogs, reading blogs, commenting on posts or answering comments on published posts. But what we choose to blog about can differ; this is an important note due to my discovery that what we choose to write about determines what benefits blogging holds to the blogger.This paper discusses the conventions of blogging as well as tries to answer the question of why blogging is so popular: why do we start blogging and why do so many choose to continue? These questions get answered by me analyzing the phenomenon that is blogging.I have studied both blogging as genre and as a kind of performance, as well as I have tried to hold an open dialogue with my informants. Thus I have concluded that blogging is to be considered a tool with many uses.

Kronoparken is a multicultural area with more than 100 different nationalities. Since we know that girls with a foreign background participate less in sport than girls with Swedish background do, we think it would be interesting to examine what kind of thoughts and experiences young girls on Kronoparken has about sport.  The purpose of this study is to examine what the girls think about the activities that are offered today. We also want to examine their thoughts about sport and gender issues.Since the aim is to identify the girl?s experiences around current activities and find out what ideas they have to improve this, we think a qualitative method is best suited. We have chosen to do interviews with two focus groups.

This study has emerged from a growing interest in students' sleeping habits. During practical training as teachers, we have noticed a discussion of students' sleeping habits, fatigue and student performance at school in relation to their sleeping habits. The purpose of this field survey was to examine students? sleeping habits and self-perceived performance ability in school in relation to sleeping habits. The material was collected from a questionnaire that was answered by 200 students in 4-6th grade and 188 students in 1-2th grade in the upper secondary school, this to give an opportunity to see if there were any differences between the different age groups.

The aim of this study was to gain a greater understanding of what social workers perceive to be mentally demanding and emotionally challenging work, and which strategies they use to handle it. I chose to interview six social workers, three of them had long experience of social work, and three of them had worked for less than a year. The justification for this choice wasthat I wanted to interview people with different experience of social work over time, to be able to see possible differences in what was perceived as mentally demanding and emotionally challenging work, and how it was handled. The social workers were interviewed with a semi structured interview manual.The results showed that the organization of the social service is not fitted to the work that social workers execute. This means that what is perceived as mentally demanding and emotionally challenging work largely depends on this.

The aim of this study is to examine the significance of having a music department at the public library in Enköping, and how the organization of the phonograms is handled. The different areas examined are the reason of the reintroduction of a music department, its budget, its users, the work with selection, the marketing, statistical data concerning loans, the work with classification, indexing, and organization of the phonograms and the future of the music department. The empirical material consists of qualitative interviews with staff connected to the music department at the public library in Enköping. For the theoretical frame, Sanna Taljas discourse analysis of music libraries in Finland is used. Talja presents three discourses which all show different views on what kind of material a music library should contain.

Wind power is expanding rapidly in Sweden. Increasing amounts of wind power sets higher requirements on balancing power and grid expansions and would affect the whole Swedish electricity system. The aim of this report is to examine the factors affecting the wind power expansion in Sweden. How many wind power plants projects will obtain building permissions and what costs and revenues can be expected? How much balancing power will be required and does a changing geographical distribution of the wind power plants reduce the need of balancing power?A survey of the county board?s official applications has been made and out of all the applications, corresponding to 80 TWh produced per year, about half of the applications are expected to obtain a permit with a major portion of them located in the north of Sweden.Especially older wind power plants, deriving revenue from Nord pool, find themselves today in a complicated financial situation.

When drivers overnight in the truck lots of electric energy is consumed by heaters, fans, lights and other extra equipment. If the engine is not running, this energy is taken from the lead/acid batteries of the truck which then needs to be recharged during operating hours. The fact that the charge acceptance of the lead/acid batteries is dependent on the temperature makes it hard to fully recharge the batteries at lower temperatures. A negative charge balance can lead to starting problems within a few days use in cold climate.In this thesis work, the effects of different battery charging concept are evaluated on the most common Scania battery (175Ah). A battery model is implemented in Matlab and some simulations of charging are made.

The aim of this literature review was to investigate whether the modern dairy cow has the time she needs to lie down and to sleep and what deprivation of these behaviors could lead to. Current research seems to agree on the fact that sleep is essential but there is no uniform explanation of the function of sleep, even though there are many theories. It is known that sleep has an important impact on the immune system and that sleep is increased in case of an infection. Sleep deprivation causes many negative effects including reduced function off the immune defense, increased metabolic activity, malnutrition and increased heart rate. It has also been found that deprivation of sleep could cause increased mortality.
