Matematiksvårigheter : Klasslärarens arbetsmetoder
The purpose of my study is to contribute knowledge about how class teachers can work with students who are in mathematics difficulties. The question at issues I have is: Which methods can class teachers in grades 1-3 use to help students with mathematics difficulties? and Which obstacles and opportunities are there in this work? To get answers to my questions, I have read relevant literature and interviewed 3 class teachers in central Sweden. Through my interview I learned that education should include and build on concrete materials and methods. I also got to know that time is the biggest obstacle to helping students with mathematics difficulties. Keywords: mathematics difficulties, methods, obstacles, opportunities.
Barnperspektiv, betyder barnrelaterat? : En kritisk diskursanalys av barnperspektivet i tjugosex kulturmyndigheters och -institutioners strategier fo?r barn- och ungaverksamhet (2012-2014)
Today the right of the child to participate freely in cultural life and the arts is a goal on the political agenda. As a consequence, in 2011, twenty-six government agencies and institutions of culture were assigned to formulate strategies for activities for children and young people. These strategies are the empirical basis of this thesis. The aim of the study is to elaborate and problematize three issues concerning children?s culture from the viewpoint of a social constructionist understanding of childhood as constructed in various, often political, practices.
Redesign of an existing apartment block in Kv Preussen to passive house
Passive houses are a relatively new concept in Sweden and by that it is meant a house without a traditional heating system. The most acknowledged passive house project is the terrace houses in Lindås, Gothenburg, which we have used as a reference. This project concerns a square apartment block. So far, no square apartment block has been built as a passive house in Sweden.The common opinion in the construction industry is that it is not economical to build extremely energy efficient houses. With Peab as commissioner our task was to investigate if that is true, if regarding the construction of a multi storey house as a passive houseMidroc, now owned by Peab, constructed in the block of Preussen in Jönköping during 2004-2005 four houses, with 132 apartments distributed on seven floors.
Energiförbrukning för putsade, odränerade träregelväggar i fuktigt respektive torrt tillstånd
In recent years, moisture damages have been noticed in rendered, undrained stud walls. The design is built on the principle one-stage tightening which means that there is no air gap in the construction. The damages have occurred when water has permeated through the rendering in leaking connections and fittings for windows, doors, canopies, balconies, terraces and awnings. Behind the plaster carrier, which consists of either polystyrene or rigid mineral wool, plasterboard has often been used as a wind protection barrier. In many cases the wind protection barrier and the underlying wooden studs have been exposed to mould and in some cases even rot.

Var man slipad förr? En experimentell undersökning av sandpapprets föregångare.
In this essay I have looked more closely at different means of grinding wood prior to the mass production and total dominance of the sandpaper in recent times as there is virtually no information to be found about this. I have also done a few replicas of how early sandpapers might have looked and as a part of creating these replicas I have also tested diffrent types of early glues. The conclusion of it all is that all the alternative grinding materials tested workd virtually as well as modern sandpaper, with some reservations. And the replicas, although rough, worked mostly well despite being constructed with simplicity in mind. This indicates that an artisan could easily construct sandpapers if he so wished..
Dalsland som turistisk produkt : Föreställningar om turistifierade rum
Market capitalism sets the conditions for how the world is conceived, experienced and organized at various spatial scales (global to local). Currently, competitiveness, entrepreneurship and economic growth are key values that shape how the world is conceived, experienced and organized. Discourses of place marketing, place branding, and the construction of places as (economic) products, are part and parcel of the heightened commodification of space. Tourism has been a major factor in the commodification of place and space. More often than not, tourism has been seen as a possibility for peripheral places, in their struggle finding new ways towards development.
Sjuksköterskans bedömning och dokumentation inom nutrition
The interest in providing a post 9/11 image of Islam to contrast the media?s frequent focus on its practitioners? alleged tendencies toward hostility and violence has in Sweden manifested itself (among other things) in an increased range of courses on Islam given by denominational Muslim organizations. In this paper I examine the construction of Islam by two Muslim organizations that offer education in Islam to non-Muslims in the context of the management?s stated goals of the education. My aim is to illustrate how discourses within these organizations are a result of the combination of local and global conditions..

Underlag för den experimentella forskningen består av litteratur. Huvudfokus ligger på gradering då plaggen i studien omfattar ett stort storleksspann innehållande 12 storlekar vilka är 86-152 centilong.
Information som inspiration : en studie av yrkesverksamma konstnärers behov och användning av information
The main purpose of this essay is to investigate professional artists experience of the need and use of information in their creative work. I have collected the material through qualitative interviews with four professional artist working with different materials and techniques. One of the results of the study is that the artists first of all used information as a source of inspiration in their creative work. They gathered their information from various scources, for example; pictures, exhibitions, visual arts, books and novells, depending on what project they are working with. Other important information scources were colleges, especially for the technical information need.
Competition for forest fuels in Sweden : exploring the possibilities of modeling forest fuel markets in a regional partial equilibrium framework
This thesis project focuses on the need for better tools for analyzing competition for forest fuels in Sweden, in particular how policy measures may influence the market and involved actors in different regions of Sweden. Raw materials from the forest have for long constituted important inputs in the Swedish forest industry. Today some of these raw materials are increasingly used as inputs also in bioenergy production, largely driven by bioenergy promoting policies, and there are signs of increased competition for forest fuels which may have various and uncertain effects on the industries in question. The thesis project explores the possibilities to adapt previously used forest sector equilibrium models into a new model suitable for analysis of Swedish forest fuel markets, called the Swedish Forest Sector Trade Model (SFSTM). The approach takes into account regional differences in supply and demand for 23 types of products produced and/or used by eight types of producers, plus consumers, in five different regions (four Swedish and one international).

InsuFlex : Framtagning och analys av högpresterande isoleringskoncept i sandwichelement
Rapportens huvudsyfte är att ta fram en isoleringskombination av högpresterande material, som ska bidra till ett förbättrat U-värde och reducerad väggtjocklek. Konstruktionen är baserad på en befintlig sandwichvägg från Strängbetong, där författarna ersatt den ursprungliga isoleringen med det utvecklade isolerskiktet för att slutligen studera väggarna med lika villkor. Den framtagna väggens isolerings- förmåga presenteras genom handberäkningar, där det erhålls U-värde och temperaturfördelningar mellan elementens olika skikt vid stationära förhållanden. Det har även utförts värmesimuleringar för att analysera samma fysikaliska faktorer dock baserat på 3D förhållanden.I samarbete med företag har flera högpresterande isoleringsmaterial valts ut att ingå i väggkonstruktionen. Genom fördjupade studier av materialens fysikaliska egenskaper kunde en komplett isoleringskombination utvecklas och fick namnet InsuFlex.
Tilläggsisolering inom byggnadsvård
Främsta anledningen till en tilläggsisolering är att det önskas bättre energihushållning i en byggnad. Detta kan göras med olika material och olika tekniker. Inom byggnadsvårdssammanhang förs det en diskussion om de fuktbuffrande materialen är bättre vid tilläggsisolering då de är hygroskopiska än de icke hygroskopiska som är mest frekvent använda i det konventionella byggandet. Denna rapport utvärderar om det finns några dokumenterade fakta som styrker att de hygroskopiska och ekologiska materialen fungerar bättre i byggnadsvårdssammanhang än de icke hygroskopiska. Olika isolermaterial från de två nämnda grupperna jämförs utifrån olika parametrar..
En belysning av Lean Production : teori och praktik ur två synsätt
Syfte: Syftet med studien är att belysa forskning och litteratur kring Lean Production utifrån två vetenskapliga synsätt. Studien syftar även till att undersöka en organisations införande av och arbete med Lean Production, för att kunna ge praktiska bidrag om hur detta arbete kan fortskrida.Metod: Studien har genomförts med en kvalitativ och öppen ansats inom ramen för en fallstudie i samarbete med Sandvik Materials Technology. Empiriskt material har samlats in genom intervjuer och observationer med och av operatörer, produktionsledning och stabspersonal. En omfattande analys av litteratur och forskning kring Lean Production har legat till grund för en teoretisk referensram.Resultat & slutsats: Belysningen av Lean Production visar att systemsynsättet beskriver konceptet som ett säkert recept för framgång, trots sin förenklade syn på organisationers påverkan av omvärldsförändringar. Det socialkonstruktivistiska synsättet visar att Lean Production har en legitimerande funktion i organisationer, men ger liten kunskap om de förändringar som sker i organisationer.
