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.

This thesis is an attempt to study how a library that is driven by a contractor works. How allinvolved parts can cooperate. The main method used, is qualitative interviews. The authorshave made a survey at the public library in Järna in Södertälje county, where Boktjänst i JärnaAB has the business on contract since 1991.Following areas have been studied: organisation and assignment; librarysphere of activity andservices; the relations to the main library, and the vision for the future of the library.Some of the conclusions drawn by the authors are that when tenders are invited for a job, thelocal conditions must be taken into consideration. To have the same employer for the wholelibrary staff are likely to simplify the matters.

Bakgrund: Unilateral benträning är ett relativt outforskat område inom träningsvetenskapen. Traditionellt genomförs fysträning för intermittenta idrotter bilateralt, trots att idrottens rörelser sker unilateralt. Det finns många studier som behandlar samband mellan agility och effektutveckling, men få som har undersökt skillnaden mellan unilateral och bilateral effektutveckling sett till agility.Syfte: Syftet med denna studie var att undersöka om unilateral effektutveckling har en starkare korrelation med agility än vad bilateral effektutveckling och agility har hos kvinnliga fotbollsspelare i division 2.Metod: Kvinnliga fotbollsspelare (n=13, ålder 23 ± 4 år) utförde vertikalhopp med tilläggsbelastning på båda benen, vänster ben och höger ben på 20 kg, 30 kg, 40 kg samt för båda benen på 50 kg och T-test och Pro agility test. Effektutveckling i förhållande till kroppsvikten på båda benen (PBbw), vänster ben (PVbw) och höger ben (PHbw) analyserades och korrelerades sedan mot T-test (Ttest) och Pro agility test (Proagility).Resultat: Signifikanta korrelationer hittades mellan agility och både vänster unilateral (PVbw-Ttest, r = -0,578) och bilateral (PBbw-Ttest, r = -0,741; PBbw-Proagility, r = -0,555) effektutveckling, där korrelationen bilateralt var starkast. Ingen signifikant korrelation hittades mellan höger ben och agility.Konklusion: Bilateral effektutveckling hade en starkare korrelation med agility än vad unilateral effektutveckling och agility hade hos kvinnliga fotbollsspelare i division 2..

According to the Swedish preschool policy documents all children should have the same opportunities to develop their early language skills regardless of their social background. The purpose of this study is to investigate how preschool teachers work with children's early literacy and language development with focus on reading aloud. The reason is to investigate how the preschool teachers work to create an environment that stimulates children's literacy and language development. Another intention is to study how often reading aloud occurs in the children's home environment and what the preschool teachers thoughts are about that. The study is based on interviews with four preschool teachers and surveys that were answered by parents.

The purpose of my study is to investigate teacher?s perceptions of their mission in the preschool class, and how they work to promote children?s written language development. What methods and working methods they use to awaken curiosity and motivate children to read and write. I am using the qualitative research method to get answers to my questions. I have made four qualitative interviews with four teachers in preschool classes from different schools.My questions are:What conceptions does teachers have about their mission in a preschool class?What different methods and approaches does teachers use to stimulate and wake children?s curiosity for reading and writing development?The theoretical basis for my study is the socio-cultural perspective, where learning occurs in interaction.

Personal trainer is a profession that has grown strongly in recent decades, and has become increasingly common in the labor market within the health sector due to the widespread and growing interest in health and self- improvement. Further more, personal training is a great example of occupations with a close interaction between producer and consumer. The purpose of this study was to examine whether and if so how, personal trainers experience that the relationship with the clients affects their own personal development. This by finding out what impact the profession has had on the personality, what impact the relationship with the clients has affected the leadership, and last what impact the relationship with the clients have had on the personality based on social and mental aspects. Based on the purpose of the study qualitative method was chosen and data was collected with qualitative interviews.

With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions. The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case. A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety of combinations for energy supply to the future area.

Pets like dogs and cats have a considerable importance for humans and research demonstrate a variety of positive economic and social effects in society due to our pet companions. The presences of pets are increasing on a global scale with correlation to economic development in low- and middle income countries. For example dogs have doubled in India over a five year period. The feed industry for dogs and cats is also the fastest growing sector in the food industry and certain pets have a significant animal protein intake which, depending on the choice of resources may provide a high ecological footprint. Examples of environmental effects with distribution and manufacturing of pet food are increased greenhouse gas emissions, waste, use of water and energy.

To support uniform and fair assessment of Swedish students? English language competences, mandatory National tests are provided both for secondary and upper secondary education. The current thesis may be seen as a contribution to the further development and validation of these tests, with regard to the likely introduction of computerized testing methods. The aim is to gain further knowledge from current research in the field, to study and elucidate international experiences of implementation, and to gather and analyze feedback from students and teachers. Based on my findings, some tentative conclusions will be drawn, and recommendations made concerning future developments.

Något av det svåraste som kan drabba oss är när en vän, familjemedlem eller släkting går bort eller drabbas av en sjukdom. Döden är en naturlig del av livet, men känns detta till trots jobbig eller rent av orättvis då den slår till. I de flesta fall är döden även resultatet av en sjukdom, en sjukdom som med dagens kunskap kanske hade varit möjlig att undvika. Eftersom döden i många fall har varit lite av ett mysterium genom människans historia har vi också lärt oss att rädas den. Nu, när den tekniska utvecklingen öppnar nya dörrar för att i förväg göra riskbedömningar av möjliga sjukdomar som kan drabba individen, så drar sig många undan.

IntroductionSuccessful training is a key for athletes to make progress in their development. Training must not just involve overload, but also must prevent the combination of excessive overload plus inadequate recovery. Athletes can experience short-term performance decrement without severe psychological or lasting other negative symptoms. Too much hard exercise or too little sleep can cause overtraining, a condition in which the subject can prevent to be away from the sport for several weeks or months. Previous studies have detected that it is important to avoid overtraining.

Young children get affected and influenced by people?s thoughts and preconceived ideas about the difference between boys and girls. How they should behave and how they are supposed to play and interact with different toys.In the goals for what the school and teachers will achieve it says in the curriculum for preschool that teachers are supposed to counteract the traditional gender roles.To get answers to the question at issue, I collected 48 individual plans of development and I have performed four observations. I put all facts together and compared the results.The main result in this study shows that the traditional gender roles are being reflected in the children?s plans of development.
