Förutsättningar och hinder för att minska elektronikavfall : En studie över hur WEEE-direktivet påverkar Sveriges förebyggande åtgärder mot elektronikavfall
To meet the growing amount of waste from electronic and electrical equipment (WEEE) EU developed, year 2002, a directive (2002/96/EG) with the objective to govern the management and reduce the amount of WEEE. The directive is based on producer responsibility which makes the producer responsible for collection and dispose of WEEE. In 2012 a new revised directive (2012/19/EU), with tougher collection targets, was developed. Both the old and the new directive states that the approach to tackle WEEE should be prioritized in order of prevention, reuse and then recycling. Hitherto the amounts of WEEE has increased every year, making it relevant to examine which type of preventive measures the directive contains and how effective they are.

"Nu är det riktigt, riktigt, riktigt, riktigt besvärligt" : En kvalitativ analys av TT:s rapportering om barn och unga som flyr ensamma till Sverige.
Today many separated children and youth up to 18 years - children in the sense of the UN Convention on the Rights of the Child - flee from war and armed conflicts around the world. Many of them come to Sweden for protection and to apply for asylum.The aim of this study is to examine how the national Swedish news agency Tidningarnas Telegrambyrå - TT - constructs the image of separated children and youth. The main research questions have been: How does TT construct the image of the separated refugee children? The more detailed questions put to examine this main question have been: what are the issues being focused in the reporting and what discourses, voices and sources are let into the journalistic material?The theoretical perspective should be considered as social constructionistic where the basic idea is that the image of the separated child also constructs the way society looks upon them, their rights and their needs, affecting how these children will be welcomed and treated when thay arrive in our society. The empirical study is a qualitative analysis of text, produced in the span 2007- April 20th 2010.
Kant och papegojan : Om exemplen i Kritik av omdömeskraften
This essay is an examination of the examples in Kant?s Critique of Judgement. The examples which I have focused on all converge in an idea of wildness. These examples of the beautiful are illuminated by a culture-historical perspective, where the literary and scientific travelogue genre is of great importance. Apart from being exegetic and culture historical, my method is also analytic.
Språket inom matematiken : En studie om vikten av det svenska språkets betydelse för matematikundervisningen
Sweden is a multicultural country and because of this the Swedish school-system should be adapted so that all pupils can develop their linguistic skills so that they can participate andunderstand the education. By using scientific work from other researchers and my own experiences from a general point of view, I noticed that pupils with foreign origin perform less good in mathematics than pupils with Swedish origin, in the Swedish education system.The purpose of this research is to find out if communication and interplay between the pupils makes it easier for them to understand mathematics and its? concepts. My research involves acertain school class were all pupils have another etnicity then the Swedish one. My aim was to find out if the pupils reached the knowledge-goals for mathematics in the third grade.
Utveckling av AGV för materialtransport till produktionscell
The main purpose of this bachelor thesis is to create a product in the form of a database that can be used for cost estimates of equipment within bio refineries. Through interviews and literature searches the key components and their costs were identified. The database was constructed in Microsoft Excel with different tabs for different categories of components; these tabs are further divided into three parts: one part with costs, one part with calculations and an information part. Most of the part with costs contains the expenses found in scientific papers during the literature study, the calculating part converts different capacities according to user preferences and the currency to euro (?) from 2010 and the information part consists of references and information about what is included in the cost.The database is a good tool for making cost estimates for bio refineries.

Zakrisdal : Område i förvandling
Zakrisdal and the west coast region of Karlstad was at one time a protected area where the ammunition factory AmF Zakrisdal 1941-1994 was situated. This factory manufactured explosives for the Swedish armed forces and for export. In this context it is an interesting paradox that the production of ammunition, mines and armorpiercing grenades for more than 50 years has preserved the environment surrounding the factory.The factory is now gone and the production is moved to Karlskoga. Plans are being made to build housing for 3-4000 residents and other enterprises within the area. The area now stands before yet another change, most likely the most profound to date.The inspiration for this work comes from the economic historic Jan Jörnmark.

Kontinuerlig glukosmätning : en möjlighet för den svenska djursjukvården?
The purpose of this scientific essay is to evaluate if a continuous glucose monitoring system is something that can benefit Swedish animal health care. The study investigates if it is medically possible to use continuous glucose monitoring systems on dogs with an apparatus attached to their bodies. Furthermore, I try to establish whether this is possible in practice and how it could be done. The keywords used were diabetes mellitus, insulin, continuous glucose monitoring, blood glucose monitoring, dog, pet owner and animal nursing care. Furthermore, I wanted to find out if this system could be an alternative to currently established methods to measure the patient?s blood glucose level.
Att arbeta med webbaserad sfi-undervisning : Sfi-elevers syn på internetbaserad undervisning som komplement till lärarledda lektioner
What are the basic thoughts formulated in the Heraclitean fragments? A cosmology, a philosophy of nature, the idea that all can be reduced to a single substance? There is always a risk that Heraclitus is fitted into a thought pattern he doesn?t belong to, if we ? from our present horizon ? focus on continuity in an attempt to frame his thinking as part of an overall progress, running from the so-called pre-Socratics to Aristotle, in the history of philosophy. If we picture the dawn of Western civilization as an early development of scientific thinking, built on a gradual and continuous growth of knowledge, we will easily go astray as we try to discover the Greek origins of philosophy. Assuming, for example, that the readings of Heraclitus as a natural philosopher have come to a dead end, can we approach the fragments from a different angle?The aim of this paper is not to give a systematized reading of all the remaining fragments of Heraclitus, but neither to necessarily contradict the various interpretations that emphasise how these shattered remains reflect a coherent philosophy.
