?Vad spelar det för roll då om inte alla syns på bild?? : En studie av representation i förskolans miljö
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.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Trans fatty acids from ruminants - and its effect on blood lipidprofile in healthy men and womenAuthor: Sophie Berg and Sara KarlssonSupervisor: Henriette PhilipsonExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 23, 2012BackgroundCardiovascular disease is the most common cause of death in Sweden. It is well known that thereis a link between high consumption of industrial trans fatty acids and cardiovascular disease, buthow natural trans fatty acids affect us remains uncertain.ObjectiveThe purpose of this article is to, based on the currently available scientific evidence, concludewhether an intake of trans fatty acids from ruminants generates an effect on the bloodlipid profile of healthy men and women.Search strategyRCT articles were obtained through searches in databases such as PubMed, The CochraneLibrary, and Scopus. Keywords used were "ruminants" AND "Cholesterol" AND "Trans FattyAcids" and "ruminants" AND "Blood Lipids" AND "Trans Fatty Acids".Selection criteriaInclusion criteria were RCT studies conducted on healthy people who did not receive medicationfor hyperlipidemia. Moreover, the results were to be based on fasting blood samples, where atleast ten hours of fasting preceded the analysis of the blood lipids.Data collection and analysisThe search generated eight studies. These were graded according to SBU:s Granskningsmall förrandomiserad kontrollerad prövning, after which four studies were selected.
En IT-baserad plattform för skolförbättring : En kvalitativ studie av lärares informations- och erfarenhetsutbyte
This thesis has created an image of the exchange of information among teachers in the Swedish upper secondary school. The study indicates that the exchange of information seems to be limited at all levels and the exchange that takes place outside the own teaching team occurs mainly through teachers personal networks. The study also shows barriers that may exist and the opportunities that an increased exchange may generate. From the picture that the empirical material provides and the theory that is presented a discussion is made around how IT can best support the organizational learning in schools. A concrete proposal is that at national level an IT platform should be created, which primarily focuses on materials that are created by its users and has an open architecture with a single login..

Examensprojekt: WERA Stockholm
This project is an attempt at creating a bag that is both functionaland has an interesting and relevant visual appearance. I have found that a bag that is functional usually have adapted certain aesthetics which are appealing only to a very limited target group. At the same time many bags that are more focused on style can be downright disabling to the carrier. I wanted to create a functional bag, and to explore new functions doing this, while working with aesthetics that stayed relevant and interesting to my target group. The bag was designed for the company Åhléns and their label WERA Stockholm, and theircustomers was the target group.
Frystorkning Kontrollerad torkning av kulturhistorisk dräkt?
Cultural objects may become wet by deliberate water cleaning, water disaster or watersoaked for other reasons. Air drying textile objects and even other organic materials from awater wet state, involves many problems depending on the strong capillarity action of water.Damages and changes such as bleeding of dyes, stains or lines of impurities from watermovement, shrinking or stiffness can occur. Freeze-drying as an alternative drying methodhas often been used for wet archaeological and marine objects, but more seldom for historicalmaterials.This bachelor thesis addresses the issue of whether freeze-drying can be an alternative controlleddrying method for historic costumes. Costumes and related objects are often compositeobjects, consisting of multiple materials, as well as being three dimensional, all of whichwill complicate drying. The purpose of this study was to investigate whether it is possible tohandle costume objects after wet cleaning for drying by freeze-drying, and if damages due tosurface tension of water, can be avoided in this way.

Hur påverkar dietärt nitrat muskelfunktionen och återhämtningen vid styrketräning? : En pilotstudie i samarbete med Karolinska Institutet och Åstrands laboratoriet.
Forskning om människans fysiologi och hur den fungerar uppdateras dagligen. Inom idrottens värld testas nya som gamla, naturliga som onaturliga preparat och träningsmetoder kontinuerligt, allt för att optimera en idrottares prestation. Ett ämne som det forskas mycket om idag är kvävemonoxid och dess påverkan i kroppen. Från att ha tolkats som ett skadligt ämne i kroppen har det gått till att möjligen kunna hjälpa hjärtsjuka patienter och även optimera idrottsutövande. Kvävemonoxid bildas i kroppen naturligt med hjälp av syre, men det kan även bildas utan syre genom intag av nitrat som hittas i många grönsaker.
