Framtida användningsområden för materialadderande tillverkning : En studie i hur materialadderande tillverkning kan användas i rymden

In this paper we have studied possible future uses for Additive Manufacturing (commonly referred to as 3D-printing) in Space. More specifically we have sought to establish how Additive Manufacturing can be used to construct structures on the Moon. Our studies have shown that Additive Manufacturing has great potential for establishing colonies on not only the Moon, but perhaps even further away from our home planet. With Contour Crafting-technology in combination with ISRU (In Situ Resource Utilization) we could, with material already present in the sediment layers of the Moon, construct advanced structures without having to transfer any extra material from Earth. This would lower the costs of establishing a colony on the Moon to such extents that it could actually be fiscally possible..

Framtidens barnbibliotek - Verksamhet och visioner

The aim of this Master's thesis is to examine the theories and visions of five futuristic projects at children's libraries in Sweden and Denmark to investigate if these projects have approaches that are significantly different from today's best practices of the libraries and the current theories behind the children's sections.More specific questions are also asked:Are the projects taking advantage of the children's perspective or is it the adult vision of children's needs that is governing?Are the projects promoting collaborations with other actors, thereby facilitating a future development of the children's library by others than librarians?The comparisons reveal that new methods and tools are beeing developed, while the traditional ambitions and views on children and children's needs are essentially unchanged. The role of the library as a social room and meeting place has increased, while its role as a place for finding and transferring information has been challenged by Internet and home computers. The library can still compete as a public place offering relevant contents and assistance by attentive, well-educated adults.In conclusion, the futuristic projects are expected to promote greater variations between children's libraries, by presenting literature, media and information in many different and more innovative ways. Such greater diversity and multiplicity would allow the libraries to market themselves with a clearer message in order to compete with other (commercial) activities for children..

Cultural Meetings in Child Health Centers : An Interview Study about Child Health Nurses experience of Intercultural Communication.

Increasing immigration to Sweden has transformed a culturally homogeneous society into a more heterogeneous one. As a consequence intercultural communication and interaction have been increasing. Child health care agencies have encountered these increases. The aim of this study was to examine what the health care professionals experienced and communicated in these intercultural environments. Eight interviews with child health care nurses were carried through at four child health care centers in the south of Sweden.

Fredagsmys ? En ritual av vår tid En kvalitativ undersökning med ett induktivt angreppssätt.

Vårt syfte har varit att exemplifiera hur fredagsmys kan gestalta sig i barnfamiljer och vad fredagsmyset kan innebära för familjens individer och individernas familj samt dess sammanhållning. Detta är en kvalitativ undersökning. Vi har valt att anta ett induktivt angreppssätt vilket innebär att vi har utgått från vårt material och därefter har alla uppsatsens delar färdigställts. Vi har med andra ord gått upptäckandets väg. Vi har varit intresserade av att undersöka varför människor gör som de gör och vad det har förbetydelse för dem men även varit intresserade av att finna mönster.

Nyanimism i Sverige : En studie om förmänskligande av hunden i samband med dennes död

This study focusses on how people in Sweden commemorate their dogs and handle their demise. By examining memorial texts for dogs that are presented by their owners on internet forums, memorial texts that are used on gravestones on an animal cemetery as well as an interview with an animal nurse, the study examines how dogs are humanized and treated in human-like ways. With theories about new animism, social acceptance (nomos) and ontology as the theoretical framework, the study provides an analysis of strategies by which people tend to humanize dogs in ways that are often similar to the handling and mourning of human deceased.                                               The empirical data illustrate how dog owners in Swedish society who have lost their beloved pet express themselves in terms of religious terminology. According to memorial texts, the dogs go to heaven, where they may be reunited with their owners, become free from their diseases, and in some cases they are buried in separate graves in animal cemeteries. The study also illustrates how dogs in Sweden today have almost equal opportunities and access to medical care as human beings.

Establishing a visual style for animated movies in a game engine

Allteftersom 3d-animerade produktioner blir alltmer vanliga både i film och i TV-produktioner och datorer blir kraftfullare varje år: så börjar realtidsrendering bli mer och mer aktuellt. I detta examensarbete kommer jag främst att koncentrera mig på att skapa koncept, modellering, texturering, behandling av material och ljussättning av en prototypkaraktär där målet är att se om det går att uppnå en så pass hög kvalité på det visuella, att det går att använda i en professionell produktion och om detta inte uppnås: ta reda på vad som saknas. Resultatet är en karaktärsmodell med en tecknad visuell stil med tillhörande återanvändbart material, som förhoppningsvis ser tillräckligt bra ut för att kunna användas i till exempel ett animerat barnprogram på TV.

Mangans inverkan på skärbarhet och mekaniska egenskaper i ett varmarbetsstål

Syftet med examensarbetet var att undersöka manganhaltens inverkan på skärbarheten och de mekaniska egenskaperna i varmarbetsstål Dievar samt kontrollera och undersöka hypotesen att material med låga Ac1 temperaturer maskinbearbetas svårare än material med högre temperaturer. Skärbarhet hos Dievar med olika Mn-halt från 0,084 till 1,59 vikts% studerades i härdat tillstånd med ett pinnfräsningstest. Skärbarheten karakteriserades genom mätning av verktygslivslängd och skärkrafter. Verktygslivslängd bestämdes av fasförslitningsutvecklingen på verktyget. Förslitningsmekanismer studerades på verktygets spån- och släppningssidor med hjälp av svepelektronmikroskop (SEM). Dragprov vid rums- och förhöjd temperatur genomfördes för att studera mangans inverkan på hållfasthetsegenskaper hos Dievar.

Energieffektivisering i offentliga byggnader : Jämförelse i elanvändning för ventilation med olika luftflödesstyrsystem

I got interested in this subject when I came in contact with Västtrafiks new paymentsystem myself during my visits in Gothenburg. I suspected problems with the informationmaterial regarding it and others seemed to share my opinion that the payment system wasdiffcult to understand. When I contacted Västtrafik and asked them about the paymentsystem they confirmed that some understanding diffculties had occurred. With thatconfirmation I decided to make it my project to look in to the matter.Some methods were used to identify the problems. The methods could again confirm thatthere were some problems with the payment system and that the information material wasa vital reason.

Evidensbaserad praktik i socialt arbete : En fallstudie av ett förbättringsarbete om hur ESL kan bidra till ökat brukarinflytande och delaktighet inom socialpsykiatri

Background: In today's Swedish health care, it is required that the various professionals must work together in teams to safer care. Several professionals with various skills expected working together in the traumateam at the care of the traumapatient. At the same time, research shows that substandard teamwork leads to avoidable errors in care. One way to improve teamwork is to practice. Purpose: The purpose of this study is to shed light on the experiences of the traumateam exercises that exercise participants feel has been favorable for the patient at the initial care of trauma patients.

Bostadsgårdar i Landskrona 1917-1937 : fallstudie av kvarteren Gripen, Lyckan och Cykeln 1

Stadens bostadsområden är byggda efter olika ideal och de skiljer sig åt beroende på hur stadsplaner och arkitektur utformades under den tid de är byggda. Olika typer av växtmaterial och olika material i markbeläggningen har använts i olika tider. Dessa material ger en viss karaktär åt utemiljön kring bostadsområdena. I min studie tittar jag närmare på vilket växtmaterial och vilka markbeläggningar som var vanligt förekommande runt bostadsområden i Landskrona mellan 1917-1937. Arbetet bygger på en fallstudie av tre specifika kvarter där jag inventerar befintligt material. Materialen jämförs sedan med gamla bilder från trakten men även med nya bilder av ett välbevarat område i Malmö, Västra sorgenfri.

Frigörelse av fosfor från färskt, fryst och torkat växtmaterial : ett laboratorieförsök för att öka förståelsen för fosfordynamiken inom växtodlingen

Phosphorus is the single most potent contributor to eutrophication of freshwater and has also been shown to contribute to the toxic algae blooms in the Baltic sea. The dynamics and paths of losses of phosphorus from arable lands are not fully understood. It is known that phosphorus can be lost directly from plant material to water. In studies where plant material has been subjected to several freeze-thaw cycles, large amounts of phosphorus have been lost. Most studies have been conducted under field conditions, with many factors effecting the measured losses of phosphorus, such as weather and type of soil. This study was performed in a controlled environment without the presence of soil. Instead of soil, small glass beads were mixed with the plant materials in vessels, to make possible homogeneous leaching with water through the mixture of glass beads and plant materials. In this study, clover, ryegrass and dry straw were cut to pieces, approximately 2 cm long.

Lägesrapport

Arbetet är inte en ensaksfråga eller en djupanalys. Det rör vid raserande och dekonstruerande. Det handlar om att föreställningar byggs upp och kan brytas ner. Det handlar om hus, ytor, skikt och strukturer. Om samhället.

Rättvisemärkning av snittblommor på den svenska marknaden :

Trade is the driving force for economic development. A greater equity in international trade can improve the livelihoods and the well being of producers in developing countries. The small-scale farmers have limited resources and have difficulties to get access to the international market. As a result of this, the Fair Trade movement has been developed and has now formed a trading partnership between the producer and the consumer. This study analyses if the Fair Trade movement can be a way for the workers in developing countries to achieve more justice in their production manner in the international trade of cut flowers and continue to be an important competitor of these products, but with better livelihood conditions. My method has been to do a comprehensive literature study of the Fair Trade movement, in which I describe the certification process, and the market of Fair Trade in Sweden.
