Nanostrukturell ytbeläggning på utsatta delar av marina drivlinor
Nowadays naval units are participating in international missions, where new and in many cases tougher conditions will affect their propulsion. This essay deals with some of the now developed nanostructure coatings and gives a presentation of how the coatings could function on some exposed parts of the naval powertrain. The essay investigates the possibility that the coatings can be used as a protective layer that will reduce or prevent wear on selected parts of the naval powertrains. As a basis for the essay, nanotechnology is described, as well as different reasons that wear occurs and application techniques for coatings The conclusion is that nanostructured coatings can be applied and provide a much better result on hardness and wear resistance as of naval powertrains compared to micro-structural coatings, both for manufacturing and renovation. The essay presents a few examples of the military utility of the nanostructure coatings as well as suggestions for further research..
Sortimentsinriktad avverkning
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.

Parents`experiences when their children are tended at hospitals
Background: In Sweden the healthcare has moved from the homes to the hospitals, as the system has developed. Parents were not allowed to visit their children when they were hospitalised in the past. It was noticed in the beginning of the 20th century that it might be harmful for the children to be left without parents at the hospital. Today it is considered a fact that the parents should stay with their hospitalised children and the healthcare is based on a family-centered care. Aim: The aim of this literature study was to elucidate parents experience when having hospitalised children.

Children?s needs differ and depend on their sense of coherence. Aim: The purpose of this study was to illuminate how children experience preparations before elective surgery.
Förstudie för kvalitetssäkringav glidande förband vid Hissmoforsvattenkraftsstation : -Specifikt för aggregat G6 och G7
Jämtkraft AB which is a power production company in Sweden has bought two newhydro power units to their station in Hissmofors. The two new generators are using aconcept with sliding stator feet to handle the thermal expansion.The concept with sliding stator feet on hydro electric generators has not beenworking satisfactory on many hydro power stations in Sweden and has caused a lot ofcosts due to long downtimes.The new station in Hissmofors is very important for Jämtkraft AB, and therefore theywant to know how to make sure that the sliding stator feet are working as theyshould. According to theories and a simplified model of the generator the stator feetdisplacement should be around 1 -1,6 mm.The generators are delivered with a surveillance system that will measure thedisplacement of the sliding stator feet. The signal from the system isn?t accessible forJämtkraft AB but it will alarm when the sliding stator feet are malfunctioning.To secure the function of the sliding feet a logger for the surveillance system or adifferent measurement system must be used; if both systems are used Jämtkraft cansecure the function of the surveillance system..
Objektskoncentration vid slutavverkning
The study is made on behalf of SCA Skog Jämtlands förvaltning which is one of five administration units that SCA Skog consists of. The purpose of the study is to investigate which reduced expenses there are according to spatial concentration of cutting areas. By increasing the spatial concentration of cutting areas it will reduce the need of movements by trailer, also reduce the number of roads that you use during the activities.
To be able to perform the study, access to a annual cuttings in nine years have been made available. From this volume new annual cuttings has been created but more concentrated. The two different results have been compared and the results show that concentration of cutting areas generates reduced need for trailer transports and less km road that has to be maintained.
But then, if it´s practical viable can be discussed.
Han är som han är - En kvalitativ studie om upplevelsen av att växa upp med ett syskon som har autism
The aim of this study is to examine the experienced life situations of siblings growing up with a brother or a sister diagnosed with autism.

Three women and one man, aged between 18-24 years, were interviewed through chatt programs on the Internet. The constituted perspective is phenomenological and the analysis were made by identifying meaning units in the text from the interviews. The theory used to interpret the result is systems theory and more specifically the structual family therapy by Salvador Minuchin.
Ungdomsbrottslighet : En studie om lokala tjänstemän inom socialt och brottsförebyggande arbetes syn på brottslighet bland unga män i en svensk förort.
The purpose of this study was to examine if there are common factors that lead to young people committing crimes according to professionals in social work, crime prevention and the police. The study also aims to examine if juveniles in Swedish suburbs commit more crimes, the consequences that follows and what actions socialworkers have for these juveniles. The study was conducted through qualitative interviews of five professionals in the area who were contacted from different units. In the analysis Goffmans (1971) theory of stigma was used and Goldberg's (2005) Conspiracy Theory. Some of the conclusions that could be drawn from the study was that there is not only one factor influencing young people to delinquency, but often combinations of different factors that lead to this.
Tala eller tiga - En kvalitativ studie om självupplevelser av medierapportering
The primary purpose of this essay is to study and describe what student?s self experiences of the media coverage of social work. The theoretical perspectives applied to analyse the empirical data are social constructionism, roles, and construction. The method of this study is qualitative and based on ten personal interviews. The material has been analysed by condensed meaning units and three themes have been used, the media coverage of social work, the relationship between social workers and media and the influence media coverage has on the students.The results given from these interviews show that the majority of the interviewed group considers the media coverage of social work as negative.
Ståndpunktsessä
The PhonePages of Sweden is a company that develops software for mobile units, especially cell phones. This thesis treats the development of, and contingencies for, a mobile phone directory, using the limited resources found in a mobile unit. The project was implemented and executed at The PhonePages with the intention of creating a product to sell to a third party.By studying different solutions, their benefits and drawbacks, an abstract picture of the product was constructed. Problems covered include compatibility problems caused by todays platform diversity as well as problems with saving, organizing and presenting data.The main goal was to create a phone directory which does not make external information retrievals. The service should contain both company and personal information, with name and phonenumber.
Palliativ vård. En litteraturstudie om sjuksköterskans syn på mötet med döende patienter och närstående.

The aim of this literature review was to describe how the nurse can prepare herself/himself for the meeting with both the patient and close ones also to describe a nurse´s need of support and education. Nine studies have been used as a foundation for this literature review. Four headlines have been crystallized out of the result, a) the view of death b) the impact of the meeting c) the importance of support d) the importance of preparation and education.
Vad kostar det?: Fallstudie av en banks kostnadsallokeringssystem
This paper investigates the internal product costing system in one of the Swedish banks with the purpose to evaluate the quality of its product costs and possible implications on decision making. The study shows that the current system distorts product costs by, among other things, using relative allocation of costs and time and by allocating all costs to individual units of products. We therefore propose an alternative product costing system, which mainly draws on ABC theory but is also adapted to the specific needs of service companies and of the Bank. This proposal is intended as a solution in this particular case and not to be generalized in other contexts. We hope however to add to the understanding of why more complex costing systems, such as the ones based on ABC theory are, according to previous studies, not widely used in practice.
Yngre barns möte med matematik
Purpose: The purpose of the study is to find out what mathematical content primary school children encounter in their free options at school.Through observation, the study defines mathematical areas that primary school students encounter in their free options at school. We want the study to show the reader the mathematics that students continuously meet without associating it with regular mathematics as taught in school.A number of mathematical areas have been defined in the analysis of the observations. These areas have subsequently been discussed more thoroughly. Finally, the areas have been arranged in a grid system to clarify the results.In our study, we have discovered that mathematics exists in all the observed situations the students participated in.We believe that observation as a method can give teachers a tool for helping students associate practical actions during their free options with the more theoretical aspects of formal teaching of mathematics. We discuss this further in the study..
