Teknik och barnböcker : hur kan tekniska system synliggöras genom sagoberÀttande
SAMMANFATTNINGDetta examensarbete Àr baserat pÄ en uppgift frÄn Small Domestic Appliances (smÄhushÄllsprodukter) pÄ Electrolux. Arbetet har handlat om att fÄ in mer naturliga materialmed ?premium? kÀnsla i deras produkter, annat Àn plast och rostfritt stÄl.Materialundersökningen har inkluderat: glas, trÀ, keramik och dekorativa tillÀmpningarför metall och plast. Hur en anvÀndare upplever ett material har ocksÄ undersökts.Information har samlats in i tvÄ undersökningar; en om trender, marknad ochkonkurrenter samt en om material, leverantörer, tillverknings- och ytbehandlingsmetoder.Tre subjektiva test har gjorts pÄ taktilitet för att fÄ reda pÄ hur vissa material upplevs avanvÀndare. Testerna utfördes med hjÀlp av materialprover, frÄgeformulÀr ochtestpersoner.Ett objektivt test pÄ friktion utfördes ocksÄ dÀr friktionskoefficienten mellan ett materialsyta och fingertopparna rÀknades ut.
Cementstabilisering av Biltemas andra lagerbyggnad i Halmstad
This is a technical report about cement stabilization in general and the stabilizationprocess during the construction of a warehouse in Halmstad, Sweden in particular and iswritten at the section for economy and technology at Halmstad University incollaboration with NCC AnlÀggning.NCC encountered variations in compression strength in the stabilized material on the firstwarehouse that they constructed for the company Biltema. In our report we used thestabilization process of the second warehouse for the same company as a reference todetermine what could be done to get a more homogeneous result for future projects.We also looked in to what testing method is the most suitable to determine the result ofthe stabilization.After interviews with people involved in the process and visits on the work site we havecome to the conclusion that the most probable cause to the variations in compressionstrength is segregation in the ballast material. This segregation can occur in severaldifferent occasions in the process such as during the production, transportation andhandling on the work site.Other causes for the variation can be improper compaction, overlapping stabilization insome places and different duration of hardening of the samples that are tested.The best way to do in situ test of the stabilized material is to do seismic investigations asthose are non-destructive tests in comparison to taking core samples and you can discoverany cracks or air bubbles in the material..

VÀstergarns kammar : en fallstudie av VÀstergarnskammarna frÄn seminariegrÀvningarna mellan Ären 2006-2010
During the years 2006-2010 Gotland University conducted seminars excavations in VĂ€stergarn parish on Gotland. Inside the wall a total of six house foundations have been found and a total of 127 combs have been registered. This thesis is based on a material study of the 127 registered medieval combs. The purpose of this thesis is to analyze the combs and with their chronology illuminate in which period the society of VĂ€stergarn was active. And also to find out what the material remains can tell us about the place and its people.
Sensory nerve conduction studies in young adults for the expansion of a reference material
Neurography is the most objective and reliable measure of the peripheral nerve function, and it is used to diagnose both local and generalized neuropathies. Neurography can measure both motor and sensory nerve functions. The principle for sensory neurgraphy is to stimulate over the nerve and record proximal or distal from the stimulated electrode.At the Department of Clinical Neurophysiology, University Hospital Uppsala, a problem has been identified, in that young adult patients tend to show unexpected abnormal neurography values in relation to the expected, indicated by the reference limits, without clinical correlates. This concerns foremost the sensory amplitudes in median and ulnar nerves. The hypothesis is that the requirement of young adults? amplitudes is too high.

Slöjdens hÄrda och mjuka material alltmer sammansmÀlta : Samarbete inom slöjdens olika material, kan det utveckla Àmnet?
Syftet med studien var att undersöka om slöjdlÀrarnas olika utbildningar spelar roll för samarbetet inom slöjdens mjuka och hÄrda material och hur ett sÄdant arbetsÀtt kan se ut. Undersökningen har Àven försökt fÄ svar pÄ om eleverna blir mer motiverade av ett arbetsÀtt dÀr materialen blandas. Dessutom har arbetet handlat om att ta reda pÄ om det finns ytterligare faktorer som spelar roll för samarbetet inom Àmnet slöjd. Genom studier av tidigare kursplaner för Àmnet i skolan och för slöjdlÀrarutbildningar har jag fÄtt en historisk tillbaka blick för vad som ingÄtt i bÄde slöjdlÀrarutbildningar och i undervisning för eleverna i skolan. I mitt sökande efter svar har 8 slöjdlÀrare intervjuats som lÀst mot bÄde tidigare och nuvarande lÀroplan för grundskolan och som har examen frÄn utbildning med behörighet i ett eller bÄda materialen.
Normkritisk pedagogik pÄ normativ grund : En analys av arbetsmaterialet Möte med mÀnniskor frÄn andra kulturer
The aim of this study has been to analyze how society is constructed in the workbook Möte med mÀnniskor frÄn andra kulturer, a popular material within the ?cultural competency? industry. The analysis has largely been carried out from the perspective of a pedagogy against oppression as it has been outlined by Kevin Kumashiro. I have found that the material combines discursive movements, which in complex and hybrid ways deconstruct, decenter, recenter and reproduce stereotypes and norms, through its normative language and pedagogy. A language constructing culture as cleanly demarcated, static and homogenous.

Thematerial is used for molecular filtration of contaminated air. Qartzene?, which is inpellet form, is porous and has a high internal surface which is a requirement for themolecular filtration. With the use of various impregnations, filtration can affect thedesired outcome.
Bildernas byggstenar : En studie om pixlar och vektorers egenskaper i form av digitala material
With a new digital world that runs parallel with our physical one, we are also facing a new type of architecture and new materials that this new architecture is built on. In this thesis I examine pixels and vectors, two of the digital materials used to create pictures. By approaching them as digital materials, I have mapped their different qualities, when and where one or the other is more or less applicable and the reason behind it. My main research question asked was the following: Are the (digital) materials challenged outside their primary fields of application, and in that case, in which way? With this question in mind, I carried out a semiotic picture analysis on four pictures, later on dividing them into four different categories, based on their different qualities and their ability to deliver information.
KVINNOR ĂR SĂLLAN ?BARA? KVINNOR : en kvinnofokuserad intersektionell studie av tvĂ„ lĂ€roböcker i Ă€mnena historia och engelska
In this study we have analysed from an intersectional perspective two textbooks Historia 1b and Progress Gold A which are purposed to be used as teaching material in Swedish schools in the subjects of History and English. Our question and reason for doing the analysis is to emphasise and make the variety of women in the books visible in order to compare that variety to the one that is demanded by the Swedish curriculum. The analysis is made from an ideology critical perspective and contains quantitative elements. Our conclusion is that the material contains both excluding and including features. Some intersectional categories are well represented while others, like functionality and religion, are not.
CirkusÀventyret En projektredogörelse om att skapa ett undervisningsmaterial
VÄr projektredogörelse handlar om utarbetandet av ett material för lÀs- och skrivinlÀrning.
Vi har stÀllt oss frÄgan; Hur skapar man ett undervisningsmaterial för lÀs och skrivinlÀrning
som med hjÀlp av det vidgade textbegreppet kan fÄnga eleverna och fasthÄlla
intresset/motivationen att lÀra? Vi kom snabbt fram till att materialet, om det ska ha dessa
kvalitéer mÄste utgÄ frÄn elever. Vi har dÀrför pratat med en grupp om tio elever för att fÄ veta
mer om deras fritidsintressen. Dessa har vi sedan vÀvt in i vÄrt material som vi döpt till
CirkusÀventyret. Materialet bestÄr av tre övergripande rubriker som Àr drama, musik och bild,
dessa resulterade sedan i ett vÀggalfabet, bok med tillhörande dramakort, sÄng och
sandpapperbokstÀver.
Metodbeskrivning för identifikation av rÄvaror med TLC
In some cases there are no methods to identify raw material which are included in dietary supplements such as tablets. The identification can be done with TLC. A general method description was developed using the raw material gotukola and appel cider vinegar. This includes processing to achieve higher concentration of the active ingredient if needed; evaluation of solubility agents to dissolve the active substance; evaluation of mobile and stationary phase and visualization of the stationary phase. The report also includes an evaluation of stationary plates..
