In this paper the possibilities to replace metal with plastic in products for the building industry were looked into. The first part was a market examination where several suitable products were found. After evaluation the door latch for in-house doors was selected to be …
… is modelled with thin ? walled pipe elements called PIPE20 which allows plastic deformation. However, in a recent analysis the results retrieved from the PIPE20 element were incorrect for strains about 1 percent. One main issue was that the PIPE20 element overestimated the …
en kraniestudie av hominider ur ett evolutionistiskt perspektiv
By examine plastic craniums from eight different hominids I wanted to find morfological characteristics that agreed with those of modern humans. The species that were selected had a plastic casting of its cranium in the laboratory at Gotland University. My focus was on species …
… for 7 days. The enrichments were wire net- and wooden shelves, wire net- and plastic cylinders, water bath, plastic ropes, branches, straw and tennis balls. One-zero scan sampling on behaviour and choice of place were performed during 3 hours and 20 minutes prior to feeding …
Bakgrundshalter och rörmaterialets inverkan vid grundvattenprovtagning
… of sampling groundwater. The groundwater was sampled from a steel pipe and a plastic pipe. Redox potential, pH, dissolved oxygen, iron content, temperature in groundwater, turbidity and conductivity were measured for different depths and pumping times in field. Also a …
Simulation tool as a help for optimization of signal distances on a railway track
The project Design analysis and proposals of plastic screw caps in Australia was performed at Högskolan Dalarna incooperation with University of Western Sydney, Australia. The Swedish company Tetra Pak, in Lund, were assigner forthe project that was performed 2006-2007. The …

… plain bearings connect the arms. The plain bearing in use today consists of a plastic ring which slides against a hard anodized joint ball. Despite the fact that the plastic contain friction-lowering additives, the bearing needs to be lubricated to prevent noise. Because the …
Ett projekt med syfte att presentera en ny lösning till katastrofbostäder
… people affected by natural disasters.My solution to the problem is based on a plastic sheet. The plastic sheet is combined with cardboard plates which gives it structure and lasting. It’s able to use the plastic sheet in a different way than before. The sheet is able to fold …
En jämförelse mellan två typer av ämnesordssystem med tanke på deras förbättring av effektiv informationsåtervinning

och analys av de slappa stråk som uppkommer
… processes. Ridges have been simulated in this project by reeling thin plastic film into selected parts in the roll. Plastic was reeled in near the core, in the middle of the roll and in the periphery of the roll. To see if the paper web had got length differences the web was …
… procedure. Effects such as initial ovalization, thinning, thickening and plastic hardening from the bending procedure are examined and the mechanical properties of pipe bends containing these effects are investigated. This has been evaluated by creating a detailed Finite Element …

… silos are not acceptable. Besides that covering and uncovering with a plastic film is labour intensive the plastic cover has today become an environmental concern because it is difficult to recycle. Another purpose of the study was therefore to investigate some alternative …
… with two layer of concrete surrounding a core of cellular plastic. Skanska is making this type of walls in a factory on Gotland. We wanted to combine the energy efficiency of passive housing with the efficiency of prefabricated sandwich-walls. Aims: To present a suggestion of a …
