Vad är ?rätt? gjutkvalitet? Hur uppnås det?

Ever since ABB has begun diecasting their rotors instead of permanent mold casting it,variation in the quality of the cast has arisen. Diecasting is performed in three differentmachines, M1, M2, M3 with 400, 660 respectively 800 tons of die locking pressures.The aim of this thesis is to answer the following questions:What is the ?right? cast quality? How is the right quality achieved?For sizes 160-180 solutions will be proposed that consider eccentricity between thelaminate and the short circuit ring as well as elimination of the thin Al film that appearson the outer periphery of the rotors.Through considering the statistic material the most often diverging rotor type has beenidentified and one of the actual rotors has been sent to a laboratory to be analyzed inorder to establish the current defects. The result of the analysis shows that there areplenty of gas- and oxide-porosity.It has been proved that every time the dies temperature decreased below 120°C thecontent of gas porosity increased. It is due to rapid solidification of metal that flowsthrough the ?cold? laminate.It has confirmed that enhanced porosity in squirrel cage causes high impedance in therotors.

?Tolkien himself would be proud? - En studie av fansens deltagande i expanderanderingen av en fiktiv värld

This essay examines fans contributions in a transmedia culture. I examine how fans relate and use the fictional worlds in the creations of their own films. The study focusing on the use of graphical elements and character design in some fan films. The examination is done by using two intertextual theories. One of the theory is Lubomir Dolezel theory on transfictional relationships and the other one is Gérad Genette theory on the realtion in transtextuality.

EU i nyheterna : En diskursanalys om EU och EU:s anseende i det svenska medieutbudet

The purpose of this essay is to analyze the EU discourse in the Swedish media. The questions that the analysis seeks to answer are; what image of EU is portrayed in the Swedish media? To which degree does the EU discourse fulfill media?s ?news values?? And what are the potential effects of the discourse on EU?s reputation? After several demarcations, I chose 8 articles form Sweden?s four largest newspapers to base the analysis on.    The theoretical and methodical structure behind this analysis is the theories and practices of Fairclough?s critical discourse analysis. Added to the theoretical structure are also theories about reputation and theories about news values. The method used in the analysis is a modified version of Fairclough?s three-dimensional model of critical discourse analysis.

Dietary intake of zinc and iron within the female population of two farming villages in the Red River Delta, Vietnam

In many developing countries, among them Vietnam, contamination of agricultural land is a major issue that has public health implications. A fast growing population, rapid urbanization and industrialization have led to air and water emissions of potentially toxic elements (PTEs), such as cadmium (Cd). Earlier studies have shown that individuals with low iron (Fe) and zinc (Zn) status absorb larger quantities of Cd than those of adequate nutritional status. The purpose of this study was to investigate and compare the Fe and Zn intake from the foods consumed by women (15-45 years) in selected households in two agricultural villag-es in the Red River delta in Vietnam. In one of the villages the residents were involved in metal (mainly Fe) recycling activity, whereas in the other village the residents had agricul-tural production as main source of income. Interviews, followed by food intake calcula-tions, were performed.

Osäker vård? En fallstudie inom svensk hälso- och sjukvård

The swedish healthcare is in many situations one of the best in the world. But still, the healthcare system includes elemnts that reduce the efficiency. Partly becouse the swedish healthcare is largely monopolized, the servicecs are not properly prized and the economic responsibility and the liability legislation is limited. The main problem this study evolves around, is how a different liability rule would change the shape of the healthcare organisation. Abouve all, how would the approach to riskmanagement and preventive and riskreducing performance change with a diffrent liability rule.

Regaining power through construction of identity? Experience of Multisystemic Therapy from a Youth?s Perspective

Literature and studies exist on how to create services in the best interest of the client or how these services have an impact on individuals. They are however mainly from a social work professional stand point and rarely from how clients would develop and create the services that can imply a life change for them. Especially when working with children under 18 years old issues of agency and age that can result in the disregard of the Convention on the Right of the Child (UNCRC). The target group of this study is therefore youth between the ages of 15 to 17 years old in three cities across Sweden to allow them to voice their opinion and experience of being in treatment. Resulting from that is the aim of this study ? to investigate how an intensive treatment method like Multisystemic Therapy is described from a client?s point of view.

Gamification av digitalt lärande : En studie av attityder om spelelement i lärplattformar

Society today is characterized by the transforming effect IT has had, the majority of the activities we perform on a daily basis involves one way or another digital technology. One area which has not yet seen the positive effects of IT is education. Despite the progress of technology, the school education has barely changed since it first saw the light of day. Our goal with this study is to investigate the possibility of implementing Gamification elements in educational environments and examine whether it could increase our young students learning motivation. We believe that this kind of implementation will have a positive effect for these young people since they have been interacting with games since they were small and are familiar with the driving force of a reward system.With this study we want to examine the opportunities and challenges that Gamification implementation brings out in a learning environment and therefore encourage and motivate our young ones to study even harder..

Praktisk och teoretisk matematik - Ur pedagogers synvinkel

In previous contact with secondary schools, we have noticed a dull setting for friluftsliv among teachers in Physical Education and Health. We suspected that both teaching and assessment are sometimes conducted in error. Under the provisions of Skolverket the teacher must involve all elements mentioned in the core content of the curriculum and the assessment of students' knowledge may be based only on what is expressed in the syllabus for each course. Research shows that the implementation of the curriculum have failed in the subjects investigated (Skolinspektionen, 2013:22). We have identified a gap of knowledge regarding the situation of friluftsliv in the course physical education 1.

GALS,Design och simulering för FPGA med VHDL

Heat, clock scew and frequency optimization are some of the problems a semiconductor designer must face. By splitting a synchrounous block into multiple pieces which comunicates asynchronously with eachother and provide them with independent clocks, these problems may be reduced. GALS (Global Asynchronous Local Synchronous) is a wrapper that wraps a synchronous block and provides it with a clock. Multiple GALS-elements will make the whole system. The clockfrequency may be independently adjusted between each block.

Alternativa verktyg, tillgänglighet och måluppfyllelse för elever i läs- och skrivsvårigheter : En fallstudie i årskurs 8 och 9

This study investigates how assistive technology tools are used in the classroom by students in reading and writing disabilities in the school years immediately prior to moving to gymnasium. Through observations and interviews with two students and two teachers this study also considers if the use of these tools can lead to increased accessibility and goal fulfilment, and whether these elements are prerequisites for success. The result shows that the students use laptops in the classroom, primarily for writing longer texts, and that in order to be successful, an early start, equipment, time and positive attitudes towards the tools are important. The students use the tools in the classroom, but they have very different feelings about how included they are in the class. The participants see a clear link between the use of assistive technology tools and increased goal fulfilment. .

The effect of vegetable fat on cheese yield and cheese properties

The production of cheese is in continuous development with objectives to in-crease productivity, achieve changes in shelf life and functional properties of the products. One concept in the development is to substitute milk fat with vegetable fats and oils in the manufacture of cheese. The objective of this study was to investigate effects on cheese yield and cheese quality of 4 different semi-hard analogue cheese products produced by substituting milk fat with vegetable fat, each analogue cheese with a specific mixture of vegeta-ble fat. As reference a cheese produced with anhydrous milk fat was used. The yield and recovery of fat and protein were determined by recording the weights of each cheese direct after press and after 20±2 days of storage and analysis of the composition of the cheeses after 20±2 days of storage. The cheese was fur-ther subjected for texture profile analysis in a TA-XT Plus Texture Analyser and analysed with Differential Scanning Calorimetry (DSC) to examine whether the fat behaves similar in the cheese as in pure form in respect to its thermal properties. The cheese yield was not significantly different when using different fats. Differ-ent amounts of water were absorbed during the water cooling.

Nya vägar i en föränderlig tid En fallstudie av ett folkbiblioteks bemötande av idén om utkontraktering av urvals- och inköpsfunktionen

Abstract: In this Master's thesis our aim is to study the situation and process regarding the decision to use outsourcing of the media acquisition function in a Swedish public library. By using New institutional theory, focusing on ways of organising and values in the organisation we are able to analyse this phenomenon. Skot-Hansens theory about three different culture political argumentation schemes, humanistic, sociological and instrumental (or market oriented), gives us the opportunity to place statements and facts into a functional theoretical context. The market oriented scheme is further clarified with the concept of New Public Management. The role of values in the institution, regarding aims and goals is stressed.

Hur säljare gör sitt val av fastighetsmäklare : en undersökning utförd i Stockholmsområdet

This essay puts its focus on examining vendors? underlying decision criterias when choosing an estate agent at the purpose of selling an apartment. The purpose is on one hand to expound the knowledge of the vendor?s decision process and on the other hand to evaluate how the choice of an estate agent is perceived to the vendor. By nine interviews we explored what reasons made vendors choose their agents and whether they were contented with their choice.

Reading the Common Foreign and Security Policy of the European Union in terms of the issue of Terrorism : An analysis on the evolution of the CFSP of the EU under the issue of Terrorism

In the post Cold-War era, world politics was transforming itself through its emerging complex issues such as terrorism and influential and interdependent actors such as the European Union. In this new era, the European Union was developing its Common Foreign and Security Policy pillar both to present a coherent and unified EU policy and to prove its political potent in order to become an influential actor on world politics. On the other side, security environment was also transforming its content through emerging actors and issues. As one of the most prominent actors of the world politics, the EU was influenced by the transformation of security environment, whose economic ?soft power? proved necessary but insufficient for being a global power in this emerging security environment.
