This paper deals with flat iron fragments from the Viking Age hall situated in Birkas Garrison, Adelsö parish in Uppland. The aim of the study was to identify which objects these flat fragments were originally derived from. The aim was also to discuss the function of these objects and their presence in the hall. This would hopefully increase the knowledge about the hall and the warriors who lived and worked there. In some cases the fragments form and placement in the hall has not provided enough information to classify the object from which they derived.

Oestrus in dairy cattle has changed over the last decades; the intensity of oestrus has declined and the duration decreased. Several studies have shown that not all dairy cows stand to be mounted, and that oestrus expression in many cases may be characterized by other behaviours. The aim of this study was to investigate oestrus behaviour in a herd of todays? high producing dairy cattle. The study was carried out at Jälla naturbruksgymnasium in Uppsala during one week in January 2011.

In this paper five different commonly used methods of making a mount for a costume in along term display was investigated: The shaping of a mannequin and a polystyrene dressstand, the making of a gypsum torso, support made out of plexiglas and polycarbonte and athree dimensional mount on a board. The materials of the Mounts were thoroughly takeninto consideration and described in the paper. One of the methods was put into practice in acase study of a Russian uniform dress coat. A gypsum torso was considered to be the mostappropriate mount in this case. The dress coat was to be displayed at the Garnisons- ochluftvärns museum in Halmstad.

Rapporten behandlar en produktutveckling av framtidens TV-fäste. Teknik och form hos TV-apparater utvecklas varje dag, detta leder till att TV-fästen måste anpassas för att följa trenderna. I samarbete med företaget People of Lava har en designprocess utförts för att utveckla framtidens TV-fäste.Rapporten behandlar en djup marknadsundersökning där statistiska, kvalitativa samt kvantitativa undersökningar utförs. Detta ligger sedan som grund för en target cost där ett produktionspris söks för att försäkra sig om en önskad vinstmarginal för företaget. Utifrån den bestämda kostnaden genomförs konceptgenereringar där form och funktioner utvecklas.

The purpose of this paper was to identify the elements and the alloys that five objects found in Birka consist of and to examine whether there are any significant differences between the presumably imported and domestic objects. The material was analyzed using a scanning electron microscope (SEM) which was equipped with an energy dispersive X-ray spectrometer (EDS) in order to identify the elements that are present and the alloys that the objects are made of. Then the SEM results were compared with the results of previous analyzes that have been performed on finds from Birka in order to investigate how the objects differ in elemental composition and to find out if there are any significant differences between them. The results showed that the objects? content of the elements analyzed varies as the copper alloys the objects are made of.

This thesis was performed at Zetterbergs Industri AB. Zetterbergs is designing, building and Mounts body systems for trucks, including dumpers and tippers. The assignment for the thesis was to design a door hinge for a spreader gate. The spreader gate is the top of the two tailgates on a dumper or tipper and opens back and outwards when tipping the cargo. The spreader gate controls the mass flow of the material being tipped.

Outsourcing means to contract out work previously done within the cooperation to a supplier.This is an increasing trend today. Traditionally companies have outsourced manufacturing butwith the growing specialization they tend to outsource other activities as well.China?s economical reforms and entrance into the World Trade Organization, WTO, hasenabled international business connections. Since China offers one of the cheapest labours inthe world, many companies have an interest in starting up an activity in the country. Themany foreign investments in China have lead to an economical growth which in turn hasmade it possible for China to invest in the Chinese competence and innovative capacity.The commissioner of this master thesis, SMS, is one of the leading actors in retrieval ofamong other things Mounts and stands for flat screens and projectors.

Every year, KTH participates in the Shell Eco Marathon, a competition whose goal is to design a vehicle that can go as far as possible using only the equivalent energy of one liter of petrol fuel. This year, one of KTH?s contributions to this race is the Agilis prototype; a car powered by a uniquely configured HCCI-engine developed at the university. The engine is dependent of several subsystems in order to work properly, among other, systems for cooling and lubrication.Combustion engines are in need of a cooling system that reduces the heat developed during the combustion. In general, two main types of cooling systems are employed; either air cooling, where the outside of the cylinder is exposed to a flow of the surrounding air, ore water cooling, where water flows in tubes around the engine, and the heat are transferred by the water to the surrounding air through a heat exchanger.The purpose of the lubrication system is to prevent the friction that builds up in the interference between moving parts in the engine.
