An investigation of the heat impact of laser cutting on the material properties when producing tensile and impact test specimens of different steel types of varying thickness has been performed. The purpose of the thesis project was to provide recommendations regarding how much material that needs to be milled from the laser cut edge before tensile and impact tests. The study has been performed partly by investigating the test specimens by heat camera when the specimens were cut in the laser cutting line and partly by performing hardness tests, investigation by microscopy, and tolerance and roughness measurements and tensile tests of the laser cut material and material produced in the traditional multi operation machine. The results show that the heat affected zone in the thicker materials is greater than previously thought of, and that the currently used recommendation has to be adjusted. The study clearly shows that the thicker the material, the greater the heat affected zone, independently of the steel type, since the thicker material takes longer time to cut.

Staphylococcus aureus is the most clinically important Staphylococcus species and is associated with high mortality in patients with positive blood cultures. S. aureus bacteria may cause a variety of disease manifestations ranging from minor skin infections to life-threatening conditions such as pneumonia, meningitis, osteomyelitis, endocarditis, toxic shock syndrome (TSS) and sepsis. This microorganism belonging to the gram positive cocci may also be part of the normal flora. In Sweden, penicillinase-stable penicillins are the primary alternatives to treat S.

Introduction: Balance between the essential nutritive substances is important for aperson to maintain health. The surgical patient can be stricken with conditions, whichhave a negative impact on this balance and can lead to malnutrition. Working as a nurseit is important to identify patients that are malnourished or is in the risk zone ofmalnourishment since 30 % of all patients in hospitals are malnourished.Aim: The aim of this study was to examine the compliance to the guidelines fornutritional assessment and parenteral nutrition on a surgical ward. Also whether thenutritional treatment/-support was reported to the next caregivers if the patient wasmalnourished or was in the risk zone of malnourishment at the time of discharge.Method: 80 patients enrolled on the ward in the beginning of year 2011 were included.Audit of patient records was made according to the hospital guidelines for nutrition andparenteral nutrition and followed a study specific protocol.Results: The examination of the case records showed that the guidelines for nutritionwere partly complied with. Nutritional treatment/-support was reported to the nextcaregivers when needed.

AbstractIn my work on language development in preschool the purpose was to examine how and to what extent the pre-school supports children with special needs in their language development. Trough qualitative interviews with four preschool teachers, I wanted to see how they work with language development in preschool. In the study, Main questions asked in the inquiry :How do teachers and support children?s language development?What techniques, resources and tools available to facilitate language development? The conclusion that I made from my inquiry is that the primary language stimulation methods teachers use to encourage children?s language development are rhymes telling, books reading and song singing based on active selection of pieces that match the children?s maturity level.And how they are using different language stimulation techniques Karlstad model, TAKK (Signs of augmentative and alternative communication) and TRAS (Early registration of language development) to promote children?s language development. Keyword: Language development, language stimulation, treatment, communication, methods..

Ungulates are causing conflicts between stakeholders due to browsing damage on forests and agricultural crops. At the same time there is a big demand of keeping high ungulate densities for sports hunting and recreational purposes. Movement patterns of ungulates are strongly correlated with forage availability. Therefore, measures affecting forage quantity and distribution might be a tool to reduce the economical losses in forestry without decreasing the ungulate densities and thereby decrease the conflict between different interest groups.This study investigated the potential biomass production and utilisation of marrow-stem kale (Brassica oleracea var. medullosa), at game fields in Misterhult, Sweden, as well as browsing effects on adjacent forests.

My aim with this diploma work is to find out if the students consider development deliberations as a good forum in order to promote their knowledge development or not. I have also examined if the development deliberation is experienced as giving for the pupil or not, what I have been studying from the pupil's perspectives.MethodI have implemented three qualitative interviews with three students from class nine in a compulsory education that lies in Botkyrka municipality. There, I have also an implemented questionnaire survey with two half classes from same class.Materials To my study I have linked literature where research aims himself in on how teachers have worked with development deliberations in the school.Results Students that I have interviewed does consider development deliberations as a knowledgep romoting forum, but most as a forum for clear about study results. The students in the survey consider development deliberations as giving only when the result turns out to bee good.Importance for teachers As each development deliberation is unique, you can not come to a certain implication that all deliberations are experienced in the same way as the result shows. But that can last stakeholder for the teacher is to see how one development deliberation can to be experienced of several students.

This master thesis in energy optimization was made during the autumn of 2006 at Käppala wastewater treatment plant in Lidingö, Stockholm. A preceding thesis, where all electricity consumption was mapped, showed that the aeration in the biological treatment is the single largest consumer in the plant, and it is therefore of interest to reduce this cost. The oxygen control strategy used at Käppala WWTP is working well from a nutrient removal point of view, but not from an economic one. The last aerobic zones have a very low oxygen consumption during low loading periods which give rise to enhanced dissolved oxygen concentrations with excessive costs and reduced denitrification as a result. But also during periods of normal loading unnecessary high oxygen concentration are sometimes given.By modifying the aeration control strategy three full-scale experiments have been made, with the intention to reduce the air consumption.

The aim of this study is to analyze how individuals experience their eating disorder, the focus being if anorexia may be perceived as a secure safe zone in the new modern world. The aim is to examine if individuals affected with anorexia nervosa understand the disorder as a solution to the modern worlds changes and the new individual freedom that it entails. This will be analyzed with the help of terms in Erich Fromms theories about escape mechanisms and Catarina Kinnvalls theories about the modern worlds ontological insecurity.The study is based on data collected from four informants of different ages and gender. The interviews were conducted through email and informants were chosen based on a strategic selection and snowball sampling. For the analysis of the empirical material Fromms escape mechanisms (authoritarianism, destructiveness and automaton conformity) and Kinnvalls theories of identity in the modern world have been used.The results of the analysis show that the eating disorder has a great significance for the individual construction and maintenance of identity and that the eating disorder becomes a safe zone to retreat to in a world of performance anxiety.

During the winter 2011 Isaksson and Andersson did a time budget study on Nordens Ark?s Przewalskis horses during daytime when there were visitors and caretakers in the park. This time budget study was made during daytime and when there were no visitors or caretakers in the park. The horses where observed in the morning (5.30-6.30 am) and in the evening (5.45-6.45 pm) during four days. In addition to a time budget, the horses? positions in the enclosure were registered.

AbstractMy purpose of the investigation is to enter deeply into the knowledge of the Individual plan of the development and to examine how teachers, pupils and parents look at the Individual plan of the development and the purpose of the Individual plan of the development in school. My question of the main problem in this investigation was to examine the expectation on the Individual plan of the development from teachers, pupils and parents and if the Individual plan of the development has been influence the cooperation of parents and the influence of the pupils also how and if teachers, pupils and parents apprehend some kinds of changes.The review of the literature begin with a closer study about our document of control, witch are the curriculum of the compulsory school (Lpo 94), The National Agency for Education General Advice for the Individual plan of the development (2005), a study of the development of the cooperation of the parents and the influence of the pupils under the years of research about it.I have in my investigation used qualitative interview in different forms like the ordinary interview, interview on telephone and focussed group interview with teachers, pupils and parents. The result of my conclusion from the investigation is that the information and the knowledge of the Individual plan of the development are important to be able to increase the influence from the pupils and a different cooperation from the parents in the development of the school with the Individual plan of the development. My examination is small and not generalised but I believe that it still can represent the attitude of the Individual plan of the development. The consequence of the investigation shows that pupils and parents have vague idea of the Individual plan of the development.

Sammandrag Syftet med detta examensarbete var att ta undersöka hur lärare resonerar kring högläsning i klassrummet samt hur de grundar sina val till den. Utifrån syftet har jag använt mig av två frågeställningar som har legat till grund för den kvalitativa intervjun som jag har genomfört med sex lärare. Lärarna arbetade i förskoleklassen ? år 5. Jag har därefter transkriberat intervjuerna som spelades in på band.

The study begins with a historical background over the fisheries development in North America and in the Baltic Sea area in Finland and Sweden. As we can see the fisheries development depends on the interaction between ecology, state of production, politic and also social factors. In Sweden the fishery politic has changed over the period of the study. In the 1970: s the main politic focus was on the fisheries progress, expansion and rationalization. The State in Sweden took a vast part in this development and gave economic support.

Learning organizations and organizational development are interesting subjects that does not examine municipal organizations and private organizations an equal amount.  Furthermore, there exists little research on the effects of competence development for individuals in a leadership role within organizations. Because of this, we wanted to examine the impact of competence development in business modeling and how it affected local government activities. Competence development is used by organizations to develop their business and achieve a greater competitive advantage, but does competence development for individuals in a leadership role lead to organizational development? This paper examines competence development in the form of a business modeling course via the Bitstreamproject and the effects that occur within three municipalities as a result of the competence development. By interviewing three participants and four coworkers within different municipalities and studied the data from the Bitstream project, we can not conclude that competence development within business modeling leads to organizational development, only that it exists a tendency for it.
