The aim of this thesis was to investigate if the robotized welding method FSW (Friction Stir Welding) could be applied for joining a rotating structure in an aero engine at Volvo Aero Corporation. FSW is expected to introduce less defects than today?s welding methods and could therefore be suitable for critical aero components. The material is the nickel based alloy Inconel 718, however a material experimentation is outside the scope of this report.The main goal of this study is to verify if the ESAB ROSIO robot based FSW-system has a suitable work space to be able to weld the rotating structure, and if the welding tool has accessibility to the joints. The FSW-process needs a rigid fixture, and a number of fix-ture concepts are presented based on a proposed weld sequence.

Background: The development of the Swedish demography is one of the most important social and economic changes ever in Swedish history. Society as well as business is facing an age chock since almost every other company owner is over 50 years old. The complexity of managing a successful succession is pointed out as a major threat to the Swedish economy by the organization Svenskt Näringsliv.Purpose: The purpose with this master thesis is to identify and analyze critical success factors for a successful succession from a going concern perspective.Research method: By using the strong aspects from the quantitative as well as the qualitative method, high level of order and systematic could be reached, without loosing too much details and depth in this particular research. The empirical data was gathered by a digital survey sent to 3000 companies. The quantitative research was complemented by 6 qualitative interviews to increase depth and reliability.Results: The study shows that there is a great incongruence between the expected problems associated to the succession and the actual outcome.

The background to the study is that within the next ten years about 50 new multi-purposeindoor arenas will be built. These are used for various events such as sports, concerts, etc. In order to achieve a high level of security in the case of danger alarm signals and alarmmessages must be heard well by the visitors. ÅF-Ingemansson wanted to show builders the importance of good speech perception and that it is not observed in arenas today. They conducted technical tests on two large multi purpose indoor arenas to develop parameters that affect speech perception in the arena.To get a subjective view of how these arenas are experienced a survey was created.

Ground construction has to a large extent been dominated by traditional meth-ods during the last 50 years. Although the construction has been changed meanwhile innovations are not accepted. In collaboration with NCC Ltd Region South, I have examined a modern con-struction methodology that has been developed by NCC for future large pro-jects. The method is divided into two central phases. Phase 1 is? Single Pro-duction? which is a preliminary period for ground constructions to come.

AbstractThe purpose of this study was to investigate the consultants' approach to the intrinsic and extrinsic motivation in temporary work agencies. We examined the motivation of three temporary work agencies to see if there are any differences in how they motivate their consultants. The intrinsic motivation comes from the own spontaneous interest while the extrinsic is related to the surrounding circumstances.We created a survey with 42 questions for the consultants, concerning motivation in order to understand their attitudes to the phenomenon of motivation.The following issues are addressed in our study:- What are consultant?s experiences of motivation in the temporary work agencies and are there any background factors that may impact?- Are there any differences in how consultants in the three different temporary work agencies are experiencing motivation?As analytical tools, we used concepts and theories of the intrinsic and extrinsic motivation based on Self-Determination theory.The results of this study showed no distinct differences between the intrinsic and extrinsic motivation of all consultants, but in general the intrinsic motivation was experienced slightly higher rated. The consultants appeared to be aware of what was expected of them and communication was valued fairly well.

A qualitative interview study how the normative gender images affects on women, their roles and positions in a drug abuse. The purpose of this study aims to shed a light at the consequences that the normative gender scenario inflicts on women with drug abuse and how these prejudices affects these women. Based on interviews with four different women who all lived with a drug abuse we have problematized how the gender system and the normative gender images affected them. We have used gender perspectives and social constructivism theories while analyzing the empirical basis. More specifically we use the theories of Butler about how gender constructs through performative actions and Hirdmans theories of the gender system.

Essay means attempt, and is a paper written based on self-experienced dilemmas, which the writer then returns to, reflect upon and discusses on the basis of literature and accepted theories. In this essay, I reflect upon my own professional role as a leisure-time pedagogue. The leisure-time pedagogue must provide activities that in different ways relate to the curriculum 2011. I have therefore a responsibility to influence the students' desire for knowledge. Focus of learning is different from the one in school, with an emphasis on informal learning.The dilemma is that I am unable to do any pedagogical work at the museum because of many conflicts.

Huruvida mänskligt beslutsfattande och riskbeteende är att betrakta somirrationellt eller rationellt beror på vilken teoretisk utgångspunkt som antas. Enligt ?expected utility?-teori och ?prospect?-teori uppfattas dessa som irrationella då det visar sig att användandet av olika heuristiker eller tumregler leder till systematiska felbeslut och teoretiska överträdelser. Utifrån ett evolutionärt perspektiv ses dock dessa överträdelser inte alls som systematiskt felaktiga utan betraktas istället som ekologiskt rationella enligt ?bounded risk distribution? modellen.

With this thesis I wanted to find out how a teacher-team in Stockholm reason about and whether they have specific expectations of male teachers in the early school years. Interviews with five teachers from pre-school to grade 3 and in after-school have shown that specific expectations of male teachers is something obvious. Are male teachers expected to enter into the role of male role models to contribute with masculinity and a male perspective? However, the informants are not able to define how a male role model is or should act. Men and women are often defined as two separate, and often as opposite, groups.

The situation that one can discern on the Swedish real estate market is that while there are several offices vacant, the need for apartments is high ? the vacancy rate for apartments is non-existent. According to the rebuilding of Skatteskrapan one will realise that the project requires a lot of money, even though it promotes the residential situation. The real estate owner experiences a risk in rebuilding real estates ? whether it will generate good yield or not.

The future climate of Sweden is expected to become warmer in the future. This would be beneficial for vineyards and may lead to a greater area being allocated for wine production. The environmental impact concerning eutrophication from Swedish vineyards has not been evaluated before. In this study nutrient balances are constructed for four Swedish vineyards with the goal to estimate the out and in flows of nutrient in the systems for the year 2010. Interviews with focus on farming practices undertaken during the year are conducted with the farmers.

The public health care sector has come under increasing pressure to cut down costs, maximize productivity and satisfy patients' needs during the 1990s and onwards. As a way of "getting more for less" quality management has been introduced. Originating in the private manufacturing industry, quality management has a strong focus on productivity and efficiency, aspects which are measured in quantitative terms. However, there are strong concerns that quality management is a means of speeding up the marketization of public health care by introducing core values much different from the ethic and medical norms that traditionally underpin health care organizations.This essay focuses on how quality management has been introduced to, and transformed by, public health care. A theoretical framework based on new institutionalism is constructed, and translation theories are used as a way of illustrating how the medical institutional environment, in fact, changes the concept of quality management.

During the last ten years the cultivation of maize in Sweden has increased and is expected to grow further. Most of the maize in Sweden becomes silage which is used to feed animals at farms. Maize has in other countries been shown to be a substrate for growth of mould and especially Aspergillus spp., Fusarium spp. and Pencillium spp. has been reported.

Aim: To examine the reaction of extreme preterm infants with regarding to body temperature and transepidermal water loss during skin-to-skin care according to Kangaroo Mother Care (KMC) during the infant?s first week of life. Method: This was a descriptive quantitatively designed study, which was a pilot study within the framework of a larger project. Nine children, with a median gestational age of 24.91 weeks, were examined by measuring body temperature (axilla and skin temperature) as well as transepidermal water loss before, during and after KMC. Results: The study showed that skin temperature tended to rise during KMC, especially for those children who were nursed with KMC for more than 60 minutes.

The difference between the public sector and the private sector in Sweden was once very small. These sectors have been united as well for the people, the organizations as for the finances. During the 1960´s and 1970´s the public sector in Sweden was expanding and after the 1980´s the people started talking more about an expanding private sector instead. The year of 2007 Hökarängen Hemtjänst Ekonomisk Förening submitted a tender to Äldreförvaltningen about a purchase of the home- help service in Hökarängen and they accept there tender.Exposing public organization for competition can be a good way to make sure that most value for the money is created and that it generates the most cost- effective organizations. The motivation factor is used to describewhat makes people perform more than what is expected of them.The purpose of this study is to describe and explain similarities and differences in working- motivation between those how are members of Hökarängen Hemtjänst Ekonomisk Förening and those how are not.
