Jag har med denna uppsats undersökt hur den franske målaren och skulptören Jean Dubuffet (1901-1985) arbetade med olika material med ett fokus på de materialval han gjorde för sina skulpturer. Jag har valt att se närmare på tre monumentala skulpturer som Dubuffet skapade under 1970-talet och även undersökt vad han genom verkens material kommunicerar. Vidare har jag analyserat och diskuterat verkens motiv och utformning för att understödja min diskussion om materialets egenskaper.Dubuffet intresserade sig som så många andra konstnärer för de avantgardisitska idéer som spred sig i mellankrigstidens Europa. Dubuffet ville föra en konstnärlig revolution mot den etablerade kultureliten och mot den klassiska konsten som han ansåg formats av den västerländska kulturen. Vidare var han mycket intresserad av material och hur material i sig kunde påverka konstens utformning och mening och han ägnade en stor del av sin karriär till att experimentera med olika naturliga material.

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..

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.

Beans are a global source of plant-based protein, and in some countries, they constitute a primary source of protein intake. With ongoing climate change, including rising temperatures, it is necessary to adapt beans to ensure a reliable food supply. An important mechanism that many plants have, to cope with high temperatures, is cooling through transpiration. During transpiration, stomata open and release water vapor. Water molecules use heat energy from the leaf to convert into gas, thereby cooling the leaf.

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.

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.

This thesis has been carried out on behalf of IV Produkt AB and intends to set an average ratio of thermal energy losses in apartment buildings that were built during the 1960-1990. This shall be derived by analyzing the total district energy consumption that has been divided into three parts: heat energy losses (the actual heating requirements), the heating of domestic hot water and heating energy consumption for the controlled ventilation.Three different residential areas that were built during the years 1962-1966 and one that was built in 1993 has been analyzed. All residential areas are located in Växjö urban and contains between four and six apartment buildings.The analyzed objects have a mechanical exhaust ventilation systems and district heating as the heating method. No own laboratory work or experiments have been done in this thesis, the calculations have been done on the basis of parameters from VEAB, interviews with property managers, and literature studies. By calculations, we have got a result that is reported in Chapter 6.

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.

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.

Based on laboratory studies with lysimeters, the concentrations of dissolved reactive phosphorus(DRP) and particulate phosphorus, which is the main part of other P (OVRP), has been studied inpercolating water. The experiment was conducted through irrigation of small soil columnscontaining clay topsoil from an experimental field in Västergötland. Three rain simulations wereconsecutively performed. DRP concentrations in the percolating water ranged between 0.2 - 0.3mg·Lclearly related to the phosphorus concentration in the soil, measured in a soil extract ofammonium lactate (P-AL). Concentrations of OVRP were relatively low and ranged between0.12 and 0.16 mg·Lwas not proven and the experiment may reflect how a relatively slow percolation of water mayrelease DRP.

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.

Background Calprotectin is a protein expressed in the cytoplasm inside the neutrophile granulocytes. During inflammatory bowel disease (IBD), the neutrophile granulocytes are involved in a complex interaction at the inflammatory area where they die and release their content into the intestinal lumen. Therefore, calprotectin in stool is a suitable marker for diagnosis and measurement of the disease-activity in patients with IBD. The most commonly used method to detect calprotectin in stool is ELISA, but the process of manual preparation of stool samples is time-consuming.Aim The objective of the study was to evaluate an extraction method that could replace manual preparation of fecal samples and to compare different methods for measuring Calprotectin in stool using two ELISA-methods from two manufacturers and one rapidtest.Methods For extraction of calprotectin from stool samples we used sample collector tubes from Epitope Diagnostics and fecal preparation kits from Roche. Two different ELISA-kits for measuring calprotectin concentration in stool were compared.

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.

This paper is a study with two different aspects, with a main focus of the match factory in Jönköping. The first aspect is about how the work situation for children looked like in the match factory during the 1900 - century. The children´s work history over time, the children?s workday and life situation on the factory and outside is described in this paper. The second aspect in this paper is about how the pupils learn about their local history in the 3 and 4 grade.

This study focuses on the development of methods for sexual determination of human skeletal remains, mainly between the years 1981 to 2007. By comparing an older analysis from 1983 (Persson and Persson) with my own on the same material, a difference of 40% was shown, which indicates that the methods has changed through time, and that these should not be used for newer conclusions about a population if the method is not throughoutly described.The main cause of the difference was identified as a change in the reliability of the sexual indicators, rather than a total change of method. Any general tendencies did not show, it is however considered that the pelvic bones are able to make a better conformity between the analyses as opposed to using the cranium..
