Råvaruinflöde inom träindustrin : En fallstudie på ett norrländskt pappersbruk
Today's global market means that raw materials are sought and bought from all over the world. This creates an higher demand for a well-functioning supply chain. In our thesis we have studied a large paper mill in northen Sweden which experiences issues with flow of raw material. Our aim has hence been to examine which aspects affect the flow of raw materials to the mill, and how these can be adressed using an IT-system. The question we sought to answer was; What factors are important to consider and how do these affect the ability of an IT-system which will support the flow of raw material at the paper mill? We have found that the problems are strongly connected to the low amount of information sharing between the mill and the suppliers.
Flödesanalys av plåtsammansättning : Strävan mot Just-In-Time och minskat slöseri
The Volvo Trucks plant in Umeå is a highy complex manufacturing facility where the same production line handles a variety of different models. This require flexible and agile processes with high quality standards. This thesis studies the flow of material through a production line and how Volvo can use their existing manufacturing monitoring system to optimize the flow of materials.The goal with the thesis is to identify eventual problems with the flow of materials and to deliver a few proposals on how the production line can improve its productivity. The theory of LEAN, Just-In-Time and Supply Chain Management serves as the scientific reference to this project. By analyzing the flow of material, performing interviews and observing the processes a few problems are identified.
Lärares syn på inkludering i grundskolans tidigare år
This study has examined how teachers in primary education with experience of inclusion look on inclusive education. The study was based on the concept of inclusion and how it is made possible in primary school. The study was conducted using semi-structured qualitative life-world interviews with three teachers in primary education with included pupils with learning disabilities in their class. The results show the complexity of having a pupil with learning disabilities in class. To interpret, follow and then assess under two syllabuses are seen as difficult.

Lakningsförsök med furubarksflis : en utredning om utsläpp av fenolföreningar samt metallsorption
The filters used today to purify water are often expensive and the need to find new filter materials is substantial. Studies of pine bark have shown that this is a material that may be used as an alternative to conventional filter materials, such as activated carbon. However, the study of pine bark has shown that a leakage of phenolic compounds may occur when using the material for water purification. Therefore, the purpose of this report is to investigate the release of phenols from pine bark, in order to evaluate the use of pine bark as a filter material. Another assignment is to investigate the amount of metals adsorbed by the filter material.
Musikens roll i förskolan : Musikens roll i förskolan ur fyra pedagogers perspektiv
With this empirical essay I want to research how and why pedagogues use music in their preschool activities. Music is important to me and in relation to the new educational plan I have cautions about that the esthetic subjects may be less prioritized than before. The purpose with my study is to find out preschool pedagogues perspective in learning and evolving children?s educational matters through music. I base my literature theories in this study on Vygotskij and Fröbels theoretical perspectives.
"När katten är borta..." : En studie kring pedagogiskt ledarskap på distans
AbstractTitle: When the cat is away? A study of pedagogical leadership at a distanceLevel: Final assignment for Degree of Master of science (one year) in Educational ManagementAuthor: Evelyn JoelssonSupervisor: Ulla SebrantDate: 2013 mayLeadership is a subject that has been discussed for many generations. Today?s leadership is something completely different than what has been practiced before, in the more hierarchical companies, when leadership was something you were born to do and the workers had no choice but to follow. In the globalised world that we live in today there are demands of a different kind than before and physical distance between leaders and their followers gets more and more common.
Traditionell skolmatematik : En studie av undervisning och lärande under en matematiklektion
Syftet med detta examensarbete är att undersöka undervisning och lärande under en matematiklektion som präglas av traditionell skolmatematik. Metoden för undersökningen var en deltagande observation av en matematiklektion i åk 3 på gymnasiet. Med hjälp av begreppen matematikens lärandeobjekt, matematiska resurser, eleven som lärande aktör och sociomatematiska normer har jag tolkat de resultat som genererats från observationen. Två slutsatser som kan dras av undersökningen är att eleverna stimuleras till att bli oberoende lärande aktörer i undervisningen av traditionell skolmatematik samt att det i första hand är läraren som synliggör potentiella matematiska resurser för eleverna. Medvetenheten om elevernas användande av matematiska resurser skulle kunna påverka elevernas lärande genom att läraren synliggör matematiska resurser på ett mer medvetet sätt..
Möjligheter och begränsningar med läroboksbaserad och laborativ matematikundervisning
Mathematics is a central topic in today's education debate, including discussion of its educational quality and various teaching methods. Today basically two different teaching methods are used; one is the textbook based method, with the book in focus and the other one the laboratory method by which teaching is performed through practical applications. The purpose of this study was to examine four primary school teachers' view of these two teaching methods by means of four relevant inquiries. By interviewing the four teachers, advantages and disadvantages were highlighted and the purpose was achieved. In order to support the analysis, two theories applied; the socio-cultural perspective and the cognitive perspective.
Det energisnåla isoleringsmaterialet
This bachelor essay is divided into two parts, the first being a construction of a single-familyhouse and the second an in-depth study of five different isolation materials, analysed from anenergy perspective.The first part, the construction of the single-family house, has been created from knowledgeacquired during three years of studying at KTH Royal institute of Technology in Stockholm, inthe program Architecture and the Built Environment. The constructed house is a one-floorhouse of 137m2with façade plaster, situated in Borlänge, Sweden. The house has a wooden framewhich is built on a on sight cast concrete foundation, on the ground. The house?s roof is a gableroof, which has an angle of 24 degrees.
En granskning av Utbildningsradions program ur ett mångfaldsperspektiv : En kvantitativ innehållsanalys av 50 program för årskurser 0-3
Utbildningsradion (Swedish Educational Broadcasting Company) is a public service broadcaster with a mandate to produce and distribute educational programmes. 80% of Swedish teachers use its products either during lessons or for professional development. Utbildningsradion?s guidelines, set by the Swedish parliament and government, state that the company?s programmes should meet the interests of the country?s whole population, regardless of their background.The purpose of this study is to examine how Utbildningsradion?s products that are intended to be used in a classroom setting for ages 6 to 9 represent the variety of children that live in Sweden and thus reflect the aforementioned guidelines. The main focus of this research project was further defined to only include the company?s television programmes produced in Sweden between 2006 and 2011 that do not have social issues as the main subject.50 programmes were analyzed using quantitative content analysis and the following results were further interpreted using mainly Kydd?s and Snead?s models for discussing representation.

Hyperverklighet och gränssnitt : Gymnasieungdomars verklighets- och identitets- konstruktion i gränssnittet mellan varandra, internet och skolan
This study investigates the internet habits of students in the Swedish gymnasium. The part that internet plays in their lives and their attitude towards the educational system is reflected upon the philosophical background that stretches from Kant to postmodern philosophers such as Baudrillard. The aim is to create knowledge about how the social aspects of the internet affects their concepts of reality and their own and others identities. The method used for the collection of empirical data has been semi-structured interviews, preformed with students in a Swedish gymnasium. The data is then interpreted against the theoretical and philosophical background.
Nivågruppering i grundskolans tidigare år : Hur och varför används den i matematikundervisningen
The aim of this essay is to examine why and how three teachers who work in elementary classes choose to use ability grouping during math lessons and what they think of ability grouping as a method to individualize the activities according to the pupil?s needs.I chose one main question for this study that is the following:What is the teacher?s point of view and experience of ability grouping in teaching mathematics?And three sub-questions:What are the motives behind the choice of ability grouping?What are the advantages of ability grouping?What are the disadvantages of ability grouping?In order to be able to answer my questions, I used the qualitative method. I interviewed three teachers who work in the elementary classes (First to fifth grade) to find out what they think about ability grouping and how it is experienced in mathematic teaching.The result shows that the common thing between these three teachers is that they don?t use ability grouping as the only teaching method. They all agree that the whole class teaching has many benefits for the pupils.
Mineraliska material som reaktiva filter för avskiljning av tungmetaller från dagvatten
Highly polluted urban storm water from e.g. highways can contain large amounts of heavy metals that may cause harm if they are discharged into recipients. To remove the heavy metals a possible low-cost method that does not require much maintenance, could be the use of reactive filters with filter materials consisting of industrial residues or other cheap mineral based materials. Dissolved metal ions are removed by reactive filters through the processes of ions binding to active sites on the surface of the filter materials, or by formation of insoluble precipitates.The ability of CaO-treated granulated blast-furnace slag, iron oxide coated sand, olivine and nepheline to remove seven heavy metals (Cr, Cd, Cu, Ni, Zn, Pb and Hg) from urban storm water was studied. Initially batch experiments were performed where the effect of pH, dissolved organic carbon (DOC) and dissolved ions on the adsorption efficiency was studied.
