Det här dokumentet är en litteraturstudie över några av de vanligaste missuppfattningarna inom arbetsområdet taluppfattning och tals användning inom matematiken. Fokus på missuppfattningarna ligger inom området för decimaltal. Studien behandlar också hur lärare kan arbeta för att minska antalet missuppfattningar i sitt arbete med decimaltal. I studien har litteratur från tidskrifterna Nämnaren och Nordisk Matematik Didaktik från Nationellt Centrum för Matematikutbildning läst. Artiklar från databasen ERIC har använts som komplement för att ge en bredare syn på missuppfattningar och lärares arbete.

The purpose of this thesis was to determine what materials should be used when creating a stimulating garden for intellectually handicapped people and whether there are materials that are better than others to use in this kind of environment. How the materials preferably can be used and how the environment should be designed to satisfy the need of each individual will also be discussed. Seriously intellectually handicapped people have the same level of intelligence as a normal 0-2 year old child. It is important to point out that these individuals can not be compared to a normal child in other aspects than the level of abstract thinking and perception of reality. As the grown up intellectually handicapped people have remained a lot longer on this stage of intelligence they have got more experience. (Kylén 1981) It is important with a lot of different experiences for the brain to develop normally, which implies the use of many different materials to achieve the best stimulation (Kylén 1981).

Lime Hempcrete consists of lime, water and hemp and creates an insulating, sound-absorbing, lightweight and environmentally friendly material that can be used in wall, roof and floor structures (Bevan & Woolley 2008). This construction method is not yet developed in Sweden as there has been a ban on the cultivation of the hemp plant. This ban on the cultivation of hemp was removed in 2003, when the material got a boost. You can use it in many different ways and not just in the construction industry (Ahlsten, 2010).In this study we have investigated the possibility to produce prefabricated wall elements of LHC. We have also studied its mechanical properties and dehydration time.

The purpose of this essay is to examine different conceptions of God children express in speech and image. The essay also concern how children's images of God are shaped in a secular and pluralistic society, such as Sweden. The children included in the investigation are in first and third grade in middle-sized Swedish town's primary school. In the essay, two methods are used, which is picture analysis and qualitative interviews. The material consists of 47 children's drawings and a smaller selection of interviews with the child's drawing as a starting point.

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.

Maternal behaviour is crucial for the development of the rat pups? behaviour and stressresponses later in life. There are numerous studies evaluating the effects of the dams?behaviours on the pups, but not many addressing what can be made for wellbeing of the ratdams when breeding. Few studies have addressed the question of how the commonly usedrearing environment effects the dams? behaviour and in the long run how it effect the ratsreared to become our research models.

Urinvägsinfektion är den vanligast förekommande vårdrelaterade infektionen varav urinvägskatetrar orsakar cirka 90 %. Syftet med studien var att undersöka om val av metod och material för urinvägskateterisering kan minska förekomsten av kateterrelaterade urinvägsinfektioner. Uppsatsen genomfördes som en litteraturstudie. Femton vetenskapliga artiklar granskades och analyserades. Katetrar belagda med hydrogel, silver och antibiotika tycks ha en hämmande effekt gällande uppkomst av urinvägsinfektioner.

The research group Soil and Water Management at the department of Soil and Environment at theSwedish University of Agricultural Sciences in Uppsala are studying greenhouse gas emissions fromcultivated peat soils. To measure carbon dioxide emissions from peat soils in the field the researchgroup are now using two portable carbon dioxide meters (Vaisala GMP343). For practical reasons,they plan to acquire a new type of automated field meter. The aim of this study is to evaluate thepresent meters to see how environmental conditions and instrument settings affect the results,which is meant to facilitate the introduction of the new field meter when the meters needs to becompared. As a part of the study the relationship between groundwater level and carbon dioxideemissions from peat soils will be investigated.The evaluation of the two carbon dioxide meters was made by connecting them to one single airtightsystem, with the aim of creating identical measurement environments.

Abstract This degree project examines how much carbon dioxide that emits during the construction phase of a road project. This is to make it possible to compare how the amount of carbon dioxide differentiates between traditional road construction and Swepave construction, which is PEAB?s alternative way to design roads. To make the comparison a calculation tool has been produced. To compare the amount of carbon dioxide emissions a reference project was needed.

Syftet med mitt examensarbete är att utifrån de didaktiska frågorna, vad, hur och varför, undersöka hur verksamma lärare introducerar och arbetar med förståelsen för likhetstecknet i skolår 1. I litteraturgenomgången går jag igenom abstrakta symboler, styrdokument, Malmers inlärningsnivåer, Vygotsky och likhetstecknet. Undersökningen är gjord på två mellanstora skolor med ca 60 elever och en liten skola med endast 10 elever, samtliga skolor ligger i mellersta Sverige.Jag har använt mig av en kvalitativ metod för min studie där jag gjort intervjuer med sammanlagt fem lärare. Grundfrågorna för intervjun är hur lärarna introducerar likhetstecknet i matematikundervisningen, vad de använder för material och uppgifter, hur de kontrollerar elevernas förståelse samt hur arbetet förändrats med tiden. Alla de intervjuade lärarna introducerar likhetstecknet i matematikundervisningen i början av höstterminen när eleverna just börjat skolan.

Syftet med undersökningen är att se på fysik med de minsta barnen på förskolan, hur det uppfattas och hur det arbetas med. Har man bra material för att arbeta med fysik och känner man att man kan det? Metoden som används i undersökningen är intervjuer av det kvalitativa slaget. Fyra förskollärare och två förskolechefer intervjuades utifrån 2 frågescheman som skiljde sig lite åt ifall man var förskollärare eller förskolechef.  Resultatet visade att förskollärarna ansåg att de inte hade så jättemycket kunskap inom fysikområdet och att det kan vara lite knepigt att arbeta med. Att se vilket material som passar att använda i en fysiksituation sågs inte som superlätt av två stycken medans två ansåg att det mesta gick att använda..

Ericsson?s factory in Kumla, Modules Kumla, became a hub for radio modules and micro base stations, which enables mobile communication through radio base stations, in 2004. Because of this the factory focuses more on the logistics operations. This has led to a need to be able to plan the capacity for the materials handling system. This master thesis has therefore been performed at Modules Kumla to develop a capacity calculation model for the material handling flow during the autumn of 2005.The work has contained a mapping of the material handling flow regarding to which activities was performed and how much time they consumed.

The report describes an ecodesign thesis performed by the author at the ÅF EcoDesign Center. The basic idea of ecodesign is to develop products with a minimized environmental load, without neglecting other significant product aspects such as function and price. During the last couple of years the public interest in environmental friendly products has increased, which has made it possible for companies to make a profit from their investments in ecodesign. To meet the increasing market for ecodesign services ÅF started the ÅF EcoDesign Center, where the company has gathered all of their competence in ecodesign in order to help companies to become greener. The task was to develop a tool for an Eco Screening.

Purpose/Aim: The aim is to examine the cooperation between the magazine Veckorevyn and its Internet based counterpart, veckorevyn.com. The purpose is also to see if veckorevyn.com is taking advantage of Internet and its possibilities.Material/Method: There are two qualitative methods used for this study: interviews and a three-pieced content analysis. The material analyzed is the magazine Veckorevyn (number 25/2008) and the website www.veckorevyn.com during a two week period.Main results: The study shows that Veckorevyn and veckorevyn.com have several differences, but also some similarities. The result is not unexpected, since we are dealing with two different types of media. There seems to be some cooperation, though on the web it is not very visible.

The aim of this thesis is to examine the possibilities and challenges facing an archive, Svenskt barnbildarkiv (SBBA), if to publish its material online. Our context for this study is image indexing. Our main questions are: How can SBBA index their pictures for a possible publication on the Internet? Are there any pros or cons in the determination of topics in children?s images, and in that case, which? What search paths are important when indexing children?s pictures, and why are they important? To answer these questions, the thesis is built on a wide study of interdisciplinary literature. But also on SBBA: s own handbook for image ?registration?, and on interviews with the persons working at the archive SBBA, in Eskilstuna.
