Phosphate is a used as a surface treatment method which is used for various purposes in the industry. In this case, phosphate coated wire is used in the processes to achieve a desirable outcome. The reason to why phosphate coated wire is used in the production process is because phosphate acts as an accumulator, where it stabilizes the lubricant on the surface of the wire. Lubrication is important because it plays a major role in the roll quality and characterizes important benefits regarding the outcome.Currently, SKF has to wash away all phosphates residues after extrusion process in an operation called tumbling. The main reason for this is simply because the surface has to be completely free from lubricants and coatings till the next step of process.

I have, with a point of departure in two case studies; the artist, curator and scientist Andreas Gedin and Maria Lind, curator and director of Tensta konsthall, contextualized with a couple of respondents; the freelance curator, writer and editor Power Ekroth and the freelance curator and artist Carl Michael von Hausswolff, conducted a field analysis on curatorial and artistic practices. I have applied key concepts in order to conduct the analysis.Furthermore, the case studies and the respondents have been placed in a contemporary artworld. These components have been related to a contemporary historical segment of the artworld. This in turn, has been related to older, international cicumstances of change and various conditions in the two subfields. I have suggested certain a proximity in the artistic and curatorial practices.

Vattenfall and Svenska Kraftnät perform start-up tests, where hydropower generators are used to power up the electrical grid in case of a blackout. To monitor the electrical grid, Phasor Measurement Units (PMU) are used. Each PMU is individually equipped with a GPS-receiver to precisely timestamp the data relative to the official time UTC. During the test, it is also of interest to timestamp the measurement signals from individual hydropower generators to later compare with PMU-data, and thus study the power grids impact on the generator. The aim is to work out an appropriate method to make these measurements and to build a data acquisition system, capable of timestamp data relative to UTC, from a generator in one of Vattenfalls hydroelectric power stations. The problem is that the generator is located in an underground station which hampers the reception of GPS-signals and wiring should be avoided if possible. Time synchronization has been solved by using Vattenfalls network, which is synchronized by the network protocol NTP.

The purpose of this study has been to investigate how the temperance movement IOGT in Karlstadcampaigned for people to vote for a referendum on alcohol in 1922 and how it has been tackled bythe local press. To answer the purpose a qualitative text interpretation has been used from IOGT'smeetings protocols and the local press used are the two largest newspapers in Karlstad during thisperiod of time, Karlstads-Tidningen and Nya Wermlands-Tidningen. The type of examinationperformed is called interpretive case study where it has been used a theoretical basis. Thetheoretical point is Habermas Bourgeois publicity also been used by Lars Båtefalk in his thesisStaten, samhället och superiet. Can the temperance movement be said to take part of the publicsphere?The results show that IOGT during this period have grown large enough to be a part of the publicwhich Båtefalk mean was not the case around 1900.

This essay studies the relationship between politicians and municipal chief officers from the point of view of the bureaucracy and its role in democracy and the substance of the chief position. I conducted interviews and observations with politicians and senior officials from the local public administration in Bromölla. The roles of the chief officer and politicians have certain common characteristics which makes it difficult to separate them. Senior officials working full time in contrast to part time politicians give them an advantage in the political process. Budget cut backs both enhance the role of politicians and chief officers in the administrative organisation.

The purpose of this study is to examine how pre-school teachers think about the importance of circle time in regard to the child's language and social development from a sociocultural perspective. Furthermore the study will include what role the educators? have during the circle time.To answer our purpose we have chosen the following question:What is the role of the teachers in the circle time?What are the teacher?s thoughts about the circle time?s importance to children's social development?What are the teacher?s thoughts about the circle time?s importance to children's language development?The study is constructed on qualitative methods, where we conducted structured interviews with six preschool teachers and observed their circle time to collect our empirical material. The study is also based on Vygotsky's sociocultural perspective which says that all learning takes place through relations and interaction with other people in the cultural context you are in. The results have shown that pre-school teachers are aware of the circle time?s importance to children?s development, and purposely plan the circle time to give children the opportunity to develop both socially and linguistically skills..

In this essay I have read the novels Wide Sargasso Sea (Jean Rhys 1966), Desirada (Maryse Condé 1997) and Invisible Cities (Italo Calvino 1972) through Édouard Glissant?s notion of the primary scene in Philosophie de la relation. Poésie en étendue. I have examined how the primary scene can be seen as a political/an aesthetical strategy in the three novels. This was done in order to question the blunted tool of the notion of the identity, which is often considered in studies regarding ?postcolonial novels?.

AbstractToday, too many construction projects are delayed and deviates from the budget. Agood project management is the basis for successful construction project. The mostcommon planning methods in the construction industry is currently Gantt chart andCPM. The problem with these is that focus is only at the time of the project anddoesn?t handle the budget.

What happens when historical theories are used as evidence in a trial? Is it possible for historians to use their own scientific tools when acting as participants in a juridical process? And how do judges deal with historical evidence? The aim of this study is to answer these questions by analyzing a specific trial, known as ?Härjedalsmålet?. Härjedalsmålet was a court case about the Sami people?s right to let their reindeer graze on private property grounds in Härjedalen during the winter season. Their claim to this right was based on prescription of time immemorial.

The improvement programme Six Sigma has often been surrounded by an air of success since it was introduced in the 1980s. Yet there are cases in which introduction of the Six Sigma improvement programme show far from successful results, even complete implementation failures with no traces of the Six Sigma methodology or any improvements after completion of the introduction. These failures can cause severe damage to organizations through direct monetary loss caused by a negative result of the investment. Indirectly the failure can cause confusion in the organization and loss of employee motivation. The conclusions have been derived based on a qualitative case study at a Swedish telecommunications company.

This thesis was done after a request from the county?s administrative board of Västmanland to provide the board with a better understanding of how green areas have changed within Västerås municipality over time.The purpose and goal of this study was thus to measure and analyze how much of the green areas within Västerås municipality that have disappeared during the past one hundred years as well as to provide a review of previous studies regarding the importance of green areas for humans as well as the biological diversity.In order to answer these questions I have in this study used a combination of a literature study, cartographic analysis as well as a time series analysis. The computer software used to do the measurements of the green areas was ArcGIS which is a geographical information system.In the cartographic and times series anlaysis measurements and analysis was made of the district map of 1911, the economic map of 1950 and the property map of 2011. The measurements show that the municipality has grown with 46,3 km2 over the last one hundred years. New neighborhoods? have emerged and the municipality has expanded.

This report evaluates whether normal approximation or resampling is to prefer for estimating the distribution of the sample mean and functions of the sample mean. The evaluation relies on simulation studies. The observations of the sample are allowed to be differently distributed. In the case of sample means they are also allowed to be dependent.For sample means the two approximations behaves very similar. The most important component whether we have a good or a bad approximation is how good the approximations catch the variance of the true distribution.

This master thesis examines the copyright law with the purpose of sorting out the consequences and the effects of the law impacted on libraries. The theories used are mainly discourse analysis and public domain theory. At the centre of the examination is the effects that copyright law bring to libraries and their ability to perform their work. A major part of this thesis is gathered around the analysis of the presumptive key words that give the structures of copyright law the possibility to claim rightfulness. This is an outspoken strategy to illustrate the discourse of copyright law.

The aim of the study was to investigate social workers and managers experiences of ending child welfare investigations within the statutory period of four months. We also investigated their experience of investigation time is used in practice. To get answers for our purpose, we conducted a qualitative study. We strategic selected three social workers and four managers to our interviews.The results showed that both social workers and managers have experience with child welfare investigations that are not completed within the statutory time. A township that departed had no experience.

In the social sciences, geopolitical theory is used in order to analyze states actions and commitments when it comes to foreign policy. This thesis develops a new understanding of geopolitical theory. Firstly, the development and application of geopolitical theory, from its foundations in the early twentieth century to contemporary geopolitical studies is discussed. Secondly a revised understanding of the variables integrated in the concept and how it can be operationalized as an analytical tool is presented and tested empirically.The critical assessment of the research field of geopolitical theory tells us that six different geopolitical perspectives have been considered the most influential (room, strategy, power projection, identity, affiliation and governance) when it comes to analyzing state action. This model is applied as an analytical tool and thus tested on a single case.
