Fällning av kisel från avloppsvatten vid Hellisheidarvirkjun - experimentell studie

This report is about the experiments with mixing of the separated water and the vacuum pump seal water at Hellisheiði power plant. This is done to prevent silica scaling and clogging in pipes and reinjection wells as well as eliminating vacuum pump seal water from the plant. The experiments were done in four stages: the first stage comprised of tests with different flows of separated water at 70°C, the second stage was carried out by mixing the separated water at 70°C and the seal water with different amounts of the seal water, the third and the fourth stages were like the first and second but with the separated water at 120°C. The results show that this method is good if the mixture is around 50/50 separated water and seal water, to control the silica scaling in the separated water and to be able to reinject the seal water with the separated water. This does not eliminate the silica scaling in all of the separated water because the amount of separated water is much more than the amount of seal water that comes from the plant. .

Den läsande fången : Fängelsebiblioteket och fångars läsning under cellfängelseepoken.

This two year master thesis examines the Swedish prison library's history during cell prison era.The investigation extends from the mid-1800s well into the 1900s. The purpose is to investigate theprison library by using a power concepts influenced by Michel Foucault. The questions revolvearound the ideas that formed the basis for the prison library and how the prison library was organizedin practice. Three types of sources are used to answer the essay questions and illustrate its pro -blems. Firstly, annual reports concerning the swedish prison system.

Att främja barns delaktighet: En studie av barnbibliotekariers syn på barns delaktighet i folkbibliotekets barnverksamheter

The objective of this thesis is to explore the prerequisites for children?s participation in the activities of the public library as expressed by six children?s librarians. Qualitative semi-structured interviews were carried out to investigate how the librarians interpreted the concept of participation and viewed power issues between children and adults. Further, difficulties and possibilities experienced in working with children?s participation and manifestations of children?s participation in everyday library work were also investigated.

Implementering av International Baccalureate Diploma Programme vid fyra skolor i Sverige : En utvärdering av motstånd och möjligheter

The aim of this essay is to analyze the implementation process of the International Baccalaureate?s Diploma Programme in four of the approximately 30 schools currently offering the IB at upper secondary level in Sweden. The starting point is a comparison between definitions in fundamental documents in the national programmes for Natural Science (NV) and Social Science (SP) on the one hand, and the IBDP on the other. The evaluation, based on Program theory, focuses in particular on the consistencies in the Organizational plans of each system.  The basic assumption is that the IB due to a deviating organizational system, different structures, aims and objectives makes a challenge for the dominating educational discourse, to use a concept by Michel Foucault, and that resistance against the IB therefore is to be expected.As a second part of the evaluation five people who either play, or have played the role of coordinators of the IB, and who thereby are responsible for the implementation, have been interviewed. The questions have been focused around in what sense the informants can confirm resistance in their implementation work due to the differences found in the first part of the evaluation, and in what ways it manifests itself.Finally, Michel Foucault?s power structures in connection to discourse analysis have been applied on the results of the two previous parts of the essay.

Identitetens gränser- en uppsats om invandrares identitetsskapande i en svensk mångkulturalistisk kontext

This essay discusses immigrants? prospects of constructing an identity in a multicultural society like Sweden. The discussion is primarily theoretical but offers a few empirical examples to demonstrate its relevance. Furthermore, the ontological standpoint of this essay draws on an understanding of the world and our knowledge as constructed which implies that identities are also constructed. The process of identity making is further understood as a relational process in which others recognition is central to the individuals own understanding of his or hers identity.

Dealing with Dragons and Standard Carriers

This master thesis concerns itself with the actual work of knowledge workers, consultants to be specific. We have through interviews and observation tried to get inside of the ?black box? of the consultants firm Consult in an effort to describe their way of working through a theoretical framework. In this framework we attempt to combine knowledge work theory with that of organizational development, OD. We try to introduce the situation of the individuals we study, the consultants, through Alvesson (2004) and Løwendahl (2005).

Marknadsföring av Urban Roots 2010

This study aims at using discourse analysis to analyze SFI students attitudes to religion and religiosity in an SFI-context. The questions are: How is the discourse constructed and maintained by religion and religiosity of SFI students in an SFI context? How do SFI participants experience that their religion has affected their time at SFI?Using a case study approach, interviews were conducted with a group of SFI students. The results show that the religious discourse in SFI is influenced by the SFI-context and affected based on the current education discourse that exists there. Furthermore, the discourse is designed and maintained by the participants private religious beliefs and the religion of the majority of the group, One canhere speak of a strong social unit forming a plausibility structure The power structure that emerges is that the majority has the power to define the significance of religion and place within the SFI context. In the SFI-context the participants view is that religion is something private that should not be expressed in the school environment.

En spindel i nätet? : Om specialpedagogers roll och förtrogenhetskunskap inom habiliteringen

This thesis is a qualitative study of a new law that was applied in December 2010. The law is called Lagen om etableringsinsatser fo?r vissa nyanla?nda invandrare, and is meant to help newly arrived immigrants that come to Sweden to establish themselves in the Swedish society. The aim of the study is to see what discourses the Swedish government produces as a result of this new law. Interesting for the study is to see what happens in the implementation stage at a local level, in this case in the municipality of O?rnsko?ldsvik.Theoretically and methodologically I emanate from critical discourse theory and institutional theory.

Måltiden som symboliskt kapital - en etnologisk studie av mat, medelklass & identitetsskapande

This paper aims to investigate how human beings uses food to found an identity, with regards to how social class affects their choice of food and if trends play a part when it comes to cooking and purchasing food. The paper applies theorist Pierre Bourdieu's concepts such as habitus, capital and field.The main part of the material is composed of four interviews with seven informants; all of which is middle class. The paper also looks at how lifestyle, taste and attitudes to consumption are used when the informants build identity. The empirical part is split into three main subjects, where I first seek to find each informants food habits. What do they eat, and what do they not eat?It showed that a large part was due to their varied lifestyles, however generally speaking the day to day meals should be quick while meals during the weekends could take longer and also cost more.

?Somliga vill ju inte dricka, men de dricker ju bara för att andra gör det? : En studie om ungdomars inställning till alkohol med nedslag i glesbygd och storstad

AimThe aim of this study was to try to understand youngsters and their attitude to alcohol in the countryside and in a large city. The questions at issue have been: How do youngsters from the countryside, who drink, and do not drink alcohol, view the school- family- and friendsituation? How do youngsters from a large city, who drink, and do not drink alcohol, view the school- family- and friendsituation? Can we understand youths? attitude to alcohol on basis of the factors: School, family and friends? Are there any differences and similarities?MethodInterviews have been implemented with four youngsters in a large city and in the countryside. To gain as much as possible from the interviews a questionnaire was distributed to two classes in year nine in the countryside, and one class in the large city. The interview material was analysed on the basis from earlier research and two theoretical models.ResultsAccording to the youngsters that drink, both in the countryside and the large city, the most common view in school was that high demands are put on the youngsters and that they should study more then they do.

Skogsbrandens påverkan på död ved :

Fire is an important ecological factor, but its consumption of coarse woody debris, CWD, has hardly received any attention. In this study, I investigate the consumption in relation to the time of initial flame exposure and propensity for continued combustion of standing CWD of pine (Pinus sylvestris). Two types of CWD were studied. Firstly, wood that had been dead for one to ten years. Secondly, wood that had been dead for several decades. In the burning experiments, logs of approx.

Myten om Governance En studie av den nyliberala normen och välfärdsstatens förfall

The thesis of this essay is that the concept of governance is a product of the neo-liberal dominant ideology and that the implementation of governance ideas will lead to a weaker nation-state. Using critical theory the essay constructs an ideal type of neo-liberalism and compares its core values with these of the governance concept as treated by the main literature in the area. The essay then focuses on the issue of the state, and discusses whether the changes leading to a demand for governance have actually weakened the state. Furthermore, the essay presents the practical use of the term governance in the EU and Sweden and problemizes the changes that the neo-liberal domination has led to in terms of power and democracy. Finally the essay discusses alternative views on the changing role of the state.

?Vi bemöter dem olika beroende på hur de bemöter oss? : -          En studie om det ömsesidiga bemötandet i professionella möten

The purpose of this study is to understand encounter by individual depictions of meetingsperceived by social workers and clients in social services. Thus, we want to understand moreabout how clients and social workers as actors encounter each other in meetings in the socialservices. The study also aims to understand how the two actors affect each other in this typeof interaction and whether there are other influencing factors. We conducted a qualitativestudy by interviewing informants with semi-structured interview questions. The informantswere comprised of three social workers and eight clients.

Development of Liquid Cooling for PCs

In recent years, existing solutions for cooling personal computer CPUs have been supplemented by a new product category, factory sealed water cooling loops. These systems, consisting of a water block with an integrated pump, a fan and a radiator, perform well compared to the air cooling solutions but are less effective than larger, custom-built water cooling systems.This project aims to explore the most important aspects of a factory sealed system and to identify possible cost-effective enhancements of the performance.The most significant differences between the different groups of water cooling loops are the block design and the pumping power. The performance of both categories is also largely dependent on the fan power, but increasing fan power has a large negative impact on the noise level.Both radiator size and fan model choice appear, in tests, to be relatively unimportant, presuming that the noise level is kept constant. The position and direction of the fan, however, has significant impact on both the temperature and the sound level.Water blocks can be designed in several different ways, both regarding the heatsink design and the flow direction. In simulation, flow with the inlet centered above the heatsink result in considerably lower pressure drop and slightly higher temperatures than flow through the block, for heatsinks with fin arrays.Creating a competitive product in this product segment certainly seems possible, as there are performance-increasing changes to be made that seemingly has little impact on the production cost.

I linje med styrdokumenten? - en fallstudie i tre läromedel i engelska

This study focuses on an analysis of three text books in English, Prime Time, Second Time, and Third Time, written for Swedish pupils between grade seven and nine. The main focus of the study is to investigate to what extent the books may be considered to follow the steering principles of the Swedish education system. The theoretical backbone of the essay is centred on the construction and maintenance of stereotypes, and is written from a social constructivist point of view. In this context, I also reason around power relations and norms in the Western society ? arguments which I, in the main analysis, apply to the books in question.
