Rapporten innefattar en jämförande studie mellan olika typer av membran och beläggningar.Främst sker en jämförelse mellan materialens förmåga att andas. Vattentäthet testas på nyamaterial och efter olika sorters nötning så som martindale, flexing och tvätt för att få en ökadförståelse för materialen. Verktyget som används i studien för att mätaånggenomsläppligheten är hudmodellen. Resultatet presenteras med ett Ret-värde vilket är enförkortning på Evaporative resistance of a textile. Metoden används för att på ett bra sättsimulera hur huden svettas.Projektet har utförts på Swerea IVF som är ett forskningsinstitut beläget i Mölndal.Hudmodellen är en av de senaste stora investeringarna på Swereas textil och plast avdelning.Resultatet av studien visar att laminat andas bättre än beläggningar, dock har bärarmaterialetstor inverkan på resultaten.

Shear Strength and Deformation Characteristics of Uppsala Clay with CRS and Standard OedometerTyra Morell Bonin & Magdalena MählerTo see how much a clay compact under different pressure one can use several different methods and in this project, two methods were used, the Standard Oedometer and a CRS apparatus. A Standard Oedometer is a full-time manual device and the CRS apparatus is a modern electric and automatic device. The aim of the project was to see similarities and differences between the two methods and examine which method that were most reliable. This has been done with repeated laboratory tests and afterward evaluations. With this information one can get a picture of how the clay will behave and how it will deform in nature.

Detta examensarbete är utfört på Sandvik Materials Technology (SMT) i Sandviken. SMT har under ett antal år arbetat mot att infria deras två största kunders, Atlas Copco Secoroc och Sandvik Mining and Construction, önskemål om en leveransprecision på 95% och en ledtid på tre dagar för storvolymprodukter av bergborrstål. Idag är leveransprecisionen tillfredsställande medan ledtiden är fem dagar. Examensarbetets syfte är att analysera vad som krävs för att infria Atlas Copco Secoroc's och Sandvik Mining and Constructions önskemål om tre dagars ledtid för storvolymprodukter. Ledtidsreduceringen ska åstadkommas med nuvarande skiftform och utan att leveransprecisionen påverkas i negativ riktning.

The aim of this study is, from a norm-critical approach, to find, investigate and analyse human representation in the visual culture of one preschool in order to understand if the children enrolled are represented or not. The research questions are: In what ways is there imagery of human representations in images and materials designed for play? What skin-colors and origins are dominant in the data collected?We carried out a qualitative study in the form of visual ethnography. This method allowed us to use a combination of different data collection tools such as photography and ethnographic field notes to collect our data. The photographs we took of images and material used for play, was then analysed through semiotic picture analysis.

The use of a bit in the mouth of a horse is being increasingly questioned with respect to its actual function, and is sometimes judged an obsolete instrument of control with potential to injure the horse. The objective of the research presented herein was twofold; firstly, to investigate the actual pressure load in the mouth of the horse with regard to oral health issues, and, secondly, to investigate whether this could be a viable method to objectively measure strength exerted by a rider/driver to the mouth of the horse especially with regard to training regimes. From the results, it is evident that these newly developed sensors have a future in equine research, although they are still under development. They can be useful both as a pedagogic teaching instrument, providing instructor and pupil with instantaneous, objective feedback on the contact between hand and mouth, as well as an aid in measuring pressure loads from our common bits. .

Projektbeskrivning: Bakgrund: Vid valsning av tunna band med hög hållfasthet används reversibla mångvalsarsverk. Kundkraven är höga vad gäller bandens planhet. Planheten kan styras genom de planhetsställdon som valsverket är utrustat med. Syfte: Förvärva kunskap om hur de olika ställdonen inverkar på planheten. Varje enskilt ställdons inverkan på planheten kan undersökas genom att genomföra en föreskriven förändring av ställdonets läge och därefter utvärdera planhetsförändringen som uppkom.

In this thesis, a transparent model of the human head has been constructed which was filled with a substance that represented the brain. This model was later crash tested. This was done in order to examine how a transparent model of the human head can be constructed to generate accurate data from crash tests. It was also done in order to examine how impacts on the front of the head can deform the rear of the brain. When a head is decelerating, the brain moves forward inside the skull and may hit the front of the skull.

To fulfill the climate target that EU and the Swedish government have decided to apply, it becomes increasingly important that the energy efficiency of existing buildings and making new buildings energy efficient as possible. Of Sweden?s total energy consumption in 2011 was 40% used by residential and service. Of the 40% of the energy consumption was 60% used for heating and domestic hot water. A report from year 2012 shows that one reason why the heating volume is so great could be due to underestimating on the energy consumption for the heating in the planning of the building.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: A vegetarian diet, a possible treatment complement for relief of symptoms ofrheumatoid arthritis? A systematic review.Author: Alexandra Ahlsén and Caroline ForsbergSupervisor: Mette AxelsenExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 22, 2012Background: Rheumatoid arthritis (RA) is a chronic remitting polyarthritis that is relapsing.Symptoms are inflammation of the joints with pain, stiffness and degradation of joint tissue.In some cases, also other parts of the body are involved. The treatment consists ofmedications to reduce pain, inflammation and degradation of joint tissue. Today, the offerednutritional treatment is primarily focused on meeting energy requirements and nutrient needs.The diet has also been discussed as symptomatic treatment, and one of the factors believed toinfluence the symptoms is meat.Objective: To assess the evidence as to whether a vegetarian diet affects the symptoms ofrheumatoid arthritis, and if so, to suggest how it can be implemented in practical dieteticswork.Search strategy The databases used in the literature search was PubMed, Scopus, and AMED.The search words used were: "rheumatiod arthritis", "vegetarian", "vegan", "diet", "meat" and"animal protein".Selection criteria: Studies investigating a vegetarian diet on the symptoms of RA wereincluded. Only RCT, clinical trial, controlled clinical trial, human studies and original articlesin English or Swedish were included.

This study focuses on the Nordic model of Extended Collective Licenses (ECL) and how this model can be used in the process of digitalising and publishing archival material such as photos, letters, maps or films. The question that this study aims to deal with is what advantages, and disadvantages, there are for archives and copyright holders when an ECL is being used. To help answering this question the ?theory of the knowledge commons? has been applied. The research question has been answered through a text analysis based on legal texts including Swedish law.

In this bachelor thesis the aim is to explore how university libraries and researchers function together. I will do this through interviews with phd students and examine how they reason on the use of libraries and other resources available in campus and witch other methods they use to gather information. The graduate students differ in where they are with their research process, but all of them work in the field of social sciences. To help me in my analysis I have adopted Wilsons model of information behaviour and modify this to better suit my purpose. My findings show that they mainly use the library to access materials and avoid use of the librarians, due to perception of low usefulness.
