The market for heavy duty engines is constantly requiring engines that should be more andmore powerful, while still maintaining low fuel consumption. As a result of increasing enginepower, the engine and coolant temperature increases as well due to insufficient coolingperformance (because of design issues, cost etc.).Also, emission legislations, both current and future, require more and more measures to betaken by engine manufacturers. One way of meeting the legislations is the use of cooled EGR(Exhaust Gas Recirculation), which also lead to increased coolant temperatures.Both these factors also naturally lead to increased engine oil temperatures, the consequencesof which are not thoroughly investigated.This thesis project aims to investigate effects of high temperatures on engine oil degradation,with focus on the greatest degradation process: oxidation. To do this several engine runs havebeen performed on a 310 hp engine with EGR to see what happens to the engine oil in a realengine when exposed to high temperatures. During the tests oil samples have been taken andanalysed for important parameters.As a complement to these engine tests some laboratory oxidation testing have also beenperformed, to be able to compare engine test data with laboratory tests.One goal of the project was to try to formulate an empirical oxidation model, which would beable to predict oil oxidation levels in an engine, given any running parameters.

Purpose: The purpose of this study is to investigate the innovation process of companies, and to analyse how important success factors and obstacles are in their innovation process.Method: The investigation strategy used for this essay was to interview companies that work with innovations. The essay has a qualitative approach. Both primary ? in the form of interviews - and secondary data ? literature found in books, scientific articles and internet - have been used to achieve our results.Results: The result of this essay is: there is not just one inovation process that is applicable to all companies. On the other hand, there are some guidelines that could be followed in the process.

This account deals with my degree in furniture design. The project was done in collaboration with the architect firm Byggnadskonst AB in a quest for the cafe chain "Vivels"Byggnadskonst AB?s mission was to make the interior of the cafe that Vivels is building in Larsberg Center on Lidingö. My assignment was to design chairs for the café. In the beginning I had even thought about designing a table, but as time past I focussed more and more on the chairs.

This master thesis is a study of the Swedish hydropower capacity to balance wind power. The Swedish government has decided that it should be possible to produce 30 TWh from wind power in the year 2020. The Swedish municipalities have to have plans for wind power plants with total yearly generation of 30 TWh. Wind power is an variable energy source that needs to be balanced by other energy sources. In Sweden the Swedish hydropower can be used for balancing a large scale introduction of wind power.

People are given better opportunities to participate in polity today. Democratic equality entails that all individuals are equal and therefore they should be included in the process of making the decisions. How can participation be defined and does it mean that having the possibility to participate means that people can influence the process of making the decisions in polity process?This paper focuses on participation and influence in polity and examine the relationship between having the possibility to participate and having the possibility to actually influence polity process on more local level. Therefore I have been examining the citizens? participation and influence in Helsingborg which is my case study.

My essay is an investigation of American Psychos Patrick Bateman. Why is Patrick Batemans identity one so easily described as shallow and superficial? I discuss theese questions from a marxists point of view putting Bateman in the context of Georg Lukács theories of reification. I compare the structure of Patrick Batemans identity with the idea of an reified identity to se how the mechanisms of reification creates the entity that is Patrick Bateman.My conclusion is that one answer to Batemans shallowness is the phenomenon of reification. To get a grasp of how shallowness might be understood I combine the theories of Lukács with Bakhtins idea of the aouthorative discourse.If one look upon reification as an aouthorative discourse and one also presume that human existence is social and verbal the conclusion is that Patrick Bateman cannot exist because of what he is an example of.

AbstractOur bachelor degree thesis was carried out in collaboration with Ivar Petterssons Järnmanufaktur AB in Smålandsstenar. We were asked to replace their wedge housing, used to fasten the wires to the power lines, with a similar structure in a plastic material. The idea for this project started with Ivar Petterssons Järnmanufaktur AB having problems with the casting quality that forced them to perform expensive tests on each of the wedge houses to ensure the quality. They are currently produced in China which is also a major drawback because it requires expensive long delivery times.The method we used is Fredy Olsson's Princip- and Primärkonstuktion (1995). We have consistently been in the project on so-called "broad front", which means that you create several sketches, ideas and changes in parallel, and then evaluates all.

The subject-matter of the following essay is to investigate the relationship between what is commonly called Deep Ecology or Biocentric Philosophy, as articulated by the co-founder of the Deep Ecology Movement, Arne Naess, and later proponents of the biocentric school of environmentalist thought. I contrast Naess? concept of Self-realization as founded in his Ecosophy T to the ideas of american conservationist and co-founder of the radical green movement Earth First! Dave Foreman, and to the controversial finnish environmentalist and ecofascist Pentti Linkola?s ideological agenda of population-reduction respectively.According to some critics of the movement, especially the social ecologist Murray Bookchin and French liberal philosopher Luc Ferry, the Deep Ecology ideology is essentially misanthropic and totalitarian in structure. A central idea among deep ecologists is that ecosystems and natural entities have intrinsic value in themselves, even outside a human social context. This idea is thought of among deep ecologists to create a philosophically sound basis for counteracting the environmental global crisis.

 The sawmill industry is a relative fragmented industry that is in an economic upswing andwith a hard competition. The customers have high demands on their suppliers and the highcustomer demand make it necessary for the companies to make a streamlining in planningand production. For that reason it is very important that the planning- and productionprocesses aren?t to complex and with a simple structure.The purpose of this report is to study and map out a marked out part of a planning- andproduction process, from adjust works to final delivery, at a company in the sawmill industry.Different methods have been used for the report, among others interviews and subordinatedmaterial.We have mapped out a marked out part of the planning- and production process at theCompany. This part we have studied, and we have analysed the process it self and otherthings connected to the process.We see the planning- and production process in the Company as complex.

The idea for this project was initiated together with one of the leaders in the forest, paper and packaging industry. To get through an A/R CDM process the company is exposed to the risk of failing the process or that the overall costs will exceed the benefits of the project. This would delete the incentives to invest in GHG removals compared to purchasing emission allowances on the carbon market. The questions that have been raised and needs clarification in the thesis are the following:? From a company perspective, what are the incentives for implementing Forest Clean Development Mechanism (CDM) projects?? What is a likely financial outcome of a reforestation CDM project on degraded land in the Guangxi province of the Peoples Republic of China?? When does an investment like this break even with the cost of buying market based carbon emission allowances? The objective of this master thesis is to carry out a research about the incentives for forest, paper and packaging companies to invest in reforestation through the clean development mechanism.

Opcon Powerbox is a product developed by Opcon together with the underlying company SRM (Svenska Rotor Maskiner) where surplus heat from the industry is used through an Organic Rankine Cycle (ORC)?process to produce electricity. An ORC-process is a thermodynamic circle process in which a refrigerant is used as the working fluid. The refrigerant makes it possible for the circle process to operate at lower temperatures than the conventional Rankine process.In this master?s thesis a data analysis software for the Opcon Powerbox has been developed in which measurement data is retrieved and handled from the Opcon Powerbox.

AbstractThe purpose of this essay was to study the parental education for adoptive parents. It´s provided by law since 1/1-2005 that parents have to participate in this education-program before they adopt. We wanted to look at what caused the change and made the education compulsory and to find out where the initiative came from, what purpose the education is supposed to fulfil, if it can facilitate for adopted children during their growth and whether the parental education can support the idea of what is best for a certain child always has to come first, according to the UN convention on the Rights of the child and the Haag-convention.The study was based on eight qualitative interviews, four with social workers, three with representatives of adoption-organisations and one with a representative of the public authority of international adoption (MIA). The conclusions of our study are that there is a risk that the education can not fulfil its purpose to prepare parents for their task, that it looses the idea of what´s best for the child and focuses on the parent instead. It seems to be more of a try out to not violate conventions signed and thereby fulfil a symbolic purpose..

The purpose of this paper is to develop an idea about geography in literature and through the study of science fiction literature examine the ?future city?. With the perspective that the city is a social construction and through the use of discourse theory, I have tried to emphasize how the future city is a representation of cultural discourses and in what way geography in literature can be used to increase our understanding of urban places. My intention with this paper has also been to find a way to connect the fictional future city with today?s urban planning discussion about the future city.

The current thesis is on the rule of law and how the principles of the rule of law are met in thenew Swedish migration process. The migration process has been subjected to criticism duringseveral years and on different occasions. The migrations process is viewed through a ?rightsof the child? perspective, foremost to seek if the rights of the child are met. The children are avulnerable group, not the least in the process of migration.
