The aim of this study was to investigate and compare the availability of construction materials affect children's constructions and play. Observations were made when the children were allowed to play and build with very little and much of the material play-doh dough in preschool. The study is aimed at children aged 3 ? 5 years. Interviews were also conducted with educators in departments where the children spent time to give support to this study.The result shows that the children create as many designs of any material amount.

Those who have invested in apartments, i.e. tenant-ownership, within the city centre of Stockholm have gained a higher than expected return on investment due to a buoyant real estate market. During the latest twelve-month period, the prices have risen more than 20 per cent in the city of Stockholm, resulting in an increased wealth together with a higher debt burden among investors. The aim of this thesis is to investigate which factors determine the prices from a micro perspective, and to what extent. An attempt is particularly made to estimate the degree of capitalization of the monthly fees; a factor which has turned out to be important according to other studies; but also to construct pricing models in order to set target prices for apartments.

De s?songsbundna blomningarna av fytoplankton utg?r en livsn?dv?ndig f?dobas i marina ekosystem samtidigt som de har en mycket viktig roll i den globala kolcykeln och d?rmed p?verkar klimatet i stort. I V?sterhavet domineras v?rblomningen till en b?rjan av kiselalger f?ljt att dinoflagellater. D? fytoplankton p?verkas av en rad olika biotiska och abiotiska faktorer har flera betydande skiften i v?rblomningens struktur observerats till f?ljd av klimatf?r?ndringar.

Mitt examensarbete är en undersökning i att ta tillvara på restmaterial ifrån möbler. Vad kan det medföra i form av estetik och värde? Vad finns det för bra metoder för att ta tillvara på material? Målet är att finna en metod för att förädla ett använt material till något nytt..

Detta arbete har syftat till att undersöka möjligheterna till förbättring av material- och produktionsstyrning vid Sandvik Mining and Construction i Sandviken. Målet har varit att skapa ett underlag för förbättrad styrning av ingående material. Nulägesanalysen visade att förbättringspotential fanns inom klassificeringen av hårdmetallämnen och komponenter. Dessutom var det önskvärt att ett kanbansystem uppfördes på de förslipade hårdmetallstiften som går till den helautomatiska STAMA-cellen. Examensarbetet har gett underlag för en omstrukturering av denna klassificering men även för en framtida uppdatering av den.

BAKGRUND: I vår bakgrund redogör vi för den tidigare forskning som bedrivits kring fysiskt undervisningsmaterial i ämnet. Vår teoretiska ram utgörs av Cummins modell för andraspråksinlärning samt Vygotskijs sociokulturella förhållningssätt vilka båda ligger till grund för vår resultatdiskussion.SYFTE: Syftet med vår undersökning är att med utgångspunkt i klassrummets konkreta material studera undervisningssituationer i ämnet svenska som andraspråk, samt undersöka vilka motiv lärare anger för sina val av material och val av aktiviteter.METOD: För att nå studiens syfte använde vi oss utav observationer och kvalitativa intervjuer. I vår undersökning ingår tre lärare på olika skolor som undervisar i ämnet svenska som andraspråk.RESULTAT: I vår undersökning fann vi att lärarna arbetade med ett varierat material och olika aktiviteter i sin undervisning utan att vara styrda av läroboken. Gemensamt för de tre lärarna var att de arbetade med skönlitteratur, läsförståelse och ordkunskap. Resultatet visade också att lärarnas motiv till det material de använde ofta grundade sig på en ambition av anpassning till elevernas tidigare kunskaper och vardagliga liv..

Atlas Copco Tools is a world leading company in tool manufacturing. The productionin Tierp works hard to improve their assembly to maintain its position. This thesis isa part of their improvement efforts to be a more Lean production.The main focus for this thesis was to identify the material flow in the kanban system,which used to supply the assembly groups, focusing on the material flow to assemblygroup 9 and the assembly group 3. Group 3's material flow within the kanban systemwas perceived to perform better than the group 9. The handling of kanban materialand their working methods in the two groups was identify those differences whichaffected the kanban system.As an alternative material supply a study were done in kiting.

AbstractAbetong in Falkenberg manufactures, among other things, small prefabricated concrete buildings for housing various installations, such as electric transformers.The aim of this dissertation is to reduce the time needed to design such buildings, by way of finding a number of standardized buildings. Standardized in such a manner as to incorporate both the needs of the manufacturer (Abetong) and its customers.To analyze the needs of the parties the work has included a market survey and calculations on the strength of these buildings.One survey was a letter questionnaire to all of Abetong?s customers who have, in the past, ordered these types of building. The aim of the questionnaire was to establish how the customers want these buildings designed.Another survey conducted was an inventory of all of Abetong?s previous projects where these types of building were manufactured.

An investigation of the heat impact of laser cutting on the material properties when producing tensile and impact test specimens of different steel types of varying thickness has been performed. The purpose of the thesis project was to provide recommendations regarding how much material that needs to be milled from the laser cut edge before tensile and impact tests. The study has been performed partly by investigating the test specimens by heat camera when the specimens were cut in the laser cutting line and partly by performing hardness tests, investigation by microscopy, and tolerance and roughness measurements and tensile tests of the laser cut material and material produced in the traditional multi operation machine. The results show that the heat affected zone in the thicker materials is greater than previously thought of, and that the currently used recommendation has to be adjusted. The study clearly shows that the thicker the material, the greater the heat affected zone, independently of the steel type, since the thicker material takes longer time to cut.

NCC ROADS Sweden east is a part of the NCC Corporation. The company mainly produces aggregates, asphalt and concrete. They have taken the environmental issues seriously and been working with that since the middle of the nineties. When manufacturing asphalt large a quantity of fossil energy is needed. The company is now about to make further progresses by manufacturing environmental friendly asphalt (?green asphalt?) with using bio-energy.

This report contains results of our study at CTC in Ljungby. CTC produces heating products such as boilers, heat pumps and additional products to their heating systems.The purpose of the report is to make a proposal how CTC will supply their new production line for heat pumps with materials. The proposal includes a production layout and a scheme for how to place the material in the production storage.The new production line will produce two different products and both of them have several variants. The line will also have a mixed flow, so the products can be produced in a random order. These conditions demand that the production line has great flexibility and that the material to all the variants can be stored in the production storage.With these conditions as input we made a layout proposal to the company.

Då jag varit ute på praktik har jag sett att elever allt för ofta bara sitter och räknar i läroboken. Vi matematiklärare måste bli bättre på att variera och börja laborera i vår undervisning. Både för att få med eleverna kunskapsmässigt i undervisningen och för att få dem intresserade och engagerade. Jag har därför i mitt examensarbete undersökt om lärare i år 4-6 använder sig utav konkret material i sin matematikundervisning. Mina problemformuleringar var:- Vad använder lärare i år 4-6 för konkreta material i sin matematikundervisning?- Hur gör lärare i år 4-6 för att konkretisera matematikundervisningen?- Varför väljer de som konkretiserar matematikundervisningen att konkretisera?Metoder som jag använt i min undersökning är litteraturstudier och intervjuer.

Background: As a part of a national health control program, Statens VeterinärmedicinskaAnstalt performs diagnostics to screen flocks for certain pathogens causing high mortality,morbidity and/or serious economical losses. There are several viruses in the programincluding IBDV (infectious bursal disease virus), IBV (infectious bronchitis virus) and NDV(Newcastle disease virus). Method: 96 serum samples were collected from different poultryflocks in Sweden and analyzed by ELISA, which are currently used in the health controlprogram as well as by a commercial prototype of a multiplex immunoassay manufactured byLuminex Corp., which is currently under evaluation at the United States Department ofAgriculture USDA. This 4-plex assay detects antibodies for the three above-mentionedviruses as well as antibodies of avian reovirus. In the context of this study the ELISAs run inroutine diagnostics as well as a REO ELISA were used as the standard for comparison.Result: The antibody concentration in serum from vaccinated chickens was high while theantibody concentration level in serum from not vaccinated chickens was low.

This essay examines how four archaeology scholars reason about gender. I have used a qualitative method in making this study of their dissertations.  The aim is to obtain a deeper understanding of gender identity in prehistory, gaining a broader appreciation of how this might be expressed through archaeological material. This essay takes its theoretical departure from postprocessual thinking, where gender perspectives, including feminist and queer theories are in focus. The result of this study shows that the scholars have a postprocessual, structuralistic theoretical perspective in common, and that they use stereotypical identity-descriptions.
