Breakdowns of welded structures are usually a consequence of fatigue loading. Fatigue fractures are commonly initiated in the region close to the weld toe but can also initiate from the weld root and from discontinuities inside the weld. The purpose of this investigation was to examine the weld quality of welded joints produced at Volvo Wheel Loaders factory in Arvika. The goal of the investigation is to give a clearer insight regarding factors influencing the fatigue strength of the welded joints and thereby give a better foundation for fatigue strength calculations.The investigation is including examination of the weld geometry, weld discontinuities and the effects of shot peening. Mainly three different methods for collecting test data have been used: Plastic replicas cast on the weld profile, weld specimens from a rear frame belonging to a wheel loader of model L110E/120E and Almen testing of the shot peening.The results showed that it is not possible to control even transition between the weld material and the base material without after treatment.

The purpose of this study was to gain a clearer picture of how after-school-care teachers? work with fundamental values in after-school care, both practically and theoretically based on the curriculum Lgr 11. I wanted to acquire a broader understanding of the school's core values and what kinds of tools teachers used to cope with their task. I proceeded with two questions:How does after-school care proactively work with core values based on gender, ethnicity and class?How does the work on value issues at after-school care centers compare with Lgr 11?In my study, I used literature studies and a qualitative analysis of five interviews with afterschool care teachers.

Since the late 1900s, the consultancy has taken a firm grip on the labor market. The consultants' work profile has been secured through agreements such as guaranteed wages. The collective has been shattered as well as higher demands are required of the employee. This results in higher work demands, workload, a reduced staffing resource and hopeless wages which can lead to health problems and depressions. Previous research shows that consultants find it stressful to be associated with two companies and some clients can also point out consultant through different attributes.

The purpose of this paper is to examine how teachers choose to work with the teaching of reading and writing skills, how teachers justify their choice of teaching method and how the documentation of student development is being used. This paper also discusses the definition of reading and writing, phonological awareness and how different reading- and writing educational methods can be combined. The gathering of information has been done through a literature review in which I have looked at past research on reading and writing. I have also conducted qualitative interviews with teachers involved in literacy learning. The result of my research shows that it is not possible to determine which literacy learning methods that are most effective.

In this master thesis a category of men otherwise often taken for granted is examined: noncriminal,non-violent men. With the help of in-depth interviews with young men who havepreviously lived a life with drugs and criminal behaviour, I examine the young men's identityand masculinity projects. To do this, I use theories by researchers R.W. Connell and MichaelS. Kimmel, among others.

The purpose of this thesis is to examine how the public libraries work towards SFI (Swedish For Immigrants) based on the views of the overseeing librarians. To study this we have asked the following research questions:What distinguishes the public libraries? work towards SFI according to the responsible librarians? What distinguishes the communication between SFI teachers and the librarians according to the responsible librarians? What opinions are held by the librarians in regards to their work with SFI?We have used a semi structured interview method with seven librarians in charge of the activities with SFI at small and medium sized public libraries in a rural area of Sweden. The theoretical framework is composed of Marianne Andersson and Dorte Skot-Hansen?s model for analysis of the local public library profile and the authors? definition of collaboration.

Social exclusion is a problem in today?s society that we feel public libraries can help resolve since they are based on the idea of equality and openness. The purpose of this essay is to examine how public librarians think and reason about the concept ?integration? as well as what role public libraries can play in immigrants? integration process. With Jose Alberto Diaz? theory on the integration process, and Marianne Andersson and Dorte Skot-Hansen?s model for analysis of the local library profile as theoretical framework, we analyzed the responses from two qualitative interviews in small groups of 2-3 librarians from two different public libraries.

När Windows Vista introducerades förändrades mappstrukturen för hur användarprofilen sparas jämfört med tidigare Windowsversioner såsom Windows XP. Denna rapport undersöker kompatibilitetsproblem med Roaming User Profiles mellan äldre och nyare versioner av operativsystemet. Syftet med rapporten var att utreda vilka problem som kan uppstå, vad det gäller Roaming User Profiles, vid en övergång från Windows XP till Windows Vista eller 7. Undersökningen genomfördes med hjälp av laborationer, litteratur och tester för att hitta problemen såväl som lösningar till dem. Resultatet visar att profiler skapade med Windows XP inte följer med till Windows Vista eller 7 utan det skapas sammanlagt två olika profiler, en för det äldre och en för det nyare operativsystemet.

This report is a result of a degree thesis at Luleå University of Technology together with Stram AB in Växjö. The project aimed to develop a size reducible bed, that gets small when folded and has a new slim design. The development of the new folding bed had the purpose to give Stram AB new ideas of how guest beds can look like and be used in the future. Information about Stram´s products and also information of other similar products on the market was gathered. A visit at a store, internet and interviews gave grater insight of the market, and of customer needs.

This paper examines the existence of two different discourses on the causes of the wars in former Yugoslavia 1991-1995 in the editorial pages in Swedish newspapers. One discourse is titled "ancient hatreds" and explains the wars as a result of old historical ethnic conflicts typical of the "Balkans" and the second discourse, "poor political leadership," explains the wars as a result of deliberately conducted nationalistic policies by political leaders.Parallel to this discourse analysis is a media theory perspective of how news is selected and processed in the newspaper's editorial texts.The paper also examines the link between each discourse and a specific view on the necessity of foreign military intervention in former Yugoslavia.The starting point of the investigation are two high-profile events in 1995 and the impact they made in the 29 editorial texts in the metropolitan newspapers that were studied.The paper shows that none of the discourses clearly dominated in these editorial texts and that a clear link between a certain discourse and the advocated measure in the form of foreign intervention couldn´t be established in the material as a whole. However, the four texts that clearly belonged to the "ancient hatreds" discourse were all in favour of foreign military intervention.The essay concludes that there is evidence of a medial feedback which means that the news to a high degree influences what is discussed in the editorials and that the evaluation and selection of news, is similar in all the studied newspapers..

The purpose of this thesis is to develop an application for mobile phones that simplifies communication. The company Doberman wanted to look at possibilities to develop such an application that uses Bluetooth? technol-ogy to communicate in ad-hoc networks. The aim has been an application to run on mobile phones in which you can send messages and files to other devices and also add a user profile with personal information to share with others. The communication will take place in temporary networks created when Bluetooth enabled devices is in range of each other.The market for mobile phones has grown rapidly over the past years and is still growing.

Länsförsäkringar in Värmland, Sweden, had during the year 2003 a total level of 6.1 percent of people on the sick-list, which was higher than average in the business (4,5%) and for salaried employees in the private sector (3,3%). The average age of those put on sick-list was 47 years, whish is four years higher than the average for the whole LF-group. The cost for the total amount of people being on sick-list at LF-company (6,1%) was estimated to 1 500 kkr, according to a calculation model coming from Försäkringskassan. For every percent the sick level could be reduced, the company would save 239 kkr. To map out the state of health of each and every collaborator in LF, the company offered all employees to make a health profile at the company's health service, Clarahälsan AB.

The report descripbs how a diplexer for a hybrid analog/digital filterbank has been constructed and tested. A diplexer divides the frequency band into two different bands that do not who doesn't overlapp each other. The sampling rate for the two ADC:s is 80 Msps, and therefore it is advantage to have zero at 80 MHz. The reason for this is that a proposed class of hybrid filterbanks with very good quality requires a zero at or close the sampling frequency to work well. The diplexer was made in three versions.

This paper is a study how students at a high school in Falun, Sweden, estimates theirperformance in an upcoming math test which is then compared with the actual grade thestudent performed. The students who participated also answered questions related to ?risksituations? to examine whether there is a correlation between how students estimate theirperformance in the context and their risk behavior, and if the students act like economicmodels assume. In agreement with previous studies, the boys in the survey tended to beoverconfident in their performance. The girls in the study were neither over- norunderconfident in her performance and no significant difference in the estimation of one'sperformance between the sexes could be proven.
