Att rekonstruera förhistoriska odlingsförutsättningar : första steget i en metodutveckling.

The aim of this work is to take the first step into a development process, with the intention to find a way of making prehistoric soil fertility a variable in archaeological landscape analysis. A pilot study is performed on the Mälar basin area, where four topographical and geological factors are reclassified and then combined, resulting in a map which expresses a relative indication of agriculture potential. The map is then compared to the distribution of Migration Period graves and gold finds. This, however, does not mean that the technique is tied to a certain prehistoric period. Because the work is intrinsically experimental, the technique as a whole is finally discussed and evaluated, and suggestions of improvements and further studies are made..

Sura Gamla Kyrka : analys av patologiska och skeletala förändringar hos sju individer

Seven individuals from Surahammar in Västmanland Sweden are analyzed for the appearance of pathological and skeletal changes. The graves, all from within the walls of a fourteenth century church, are dated from the Viking age to late eighteenth century. The aim of this scientific essay is to find pathological conditions by doing an osteological analyze, x-ray analysis, an osteoporosis measurement and letting orthopedists assess the individuals. The aim is also to say something about the individuals? general health and how they experience the changes they have in the skeleton.

Gårdsbutiken i stan :

We have a business proposal. Instead of the consumers visit the country side in order to purshase we are interested in starting a shop with only regional produced products in the city. We have our base in a part of Sweden called Östergötland, therefore we have investigated the market for such a store in Östergötlands biggest city, called Linköping. The conclusion is that the store must sell food produced in the region. Another conlusion is that the store must be located near a bigger supermarket. Our main selling points are quality and that the food is produced in the near region.

Deaktivering av metanisering katalysatorer

A titania-supported nickel catalyst was prepared and tested in methanation in order to evaluate its catalytic properties (activity, selectivity and specially, activity loss), and compare it with an alumina-supported nickel catalyst.The titania-supported catalyst did not only show higher stability than alumina, but also presented a different cause of deactivation, carbon formation. In addition, a kinetic model was obtained for the titania-supported catalyst, and a study of the effect of different operating conditions (temperature, composition and partial pressures of synthesis gas and water) on the deactivation rate and carbon formation of this catalyst was performed.

Energieffektivisering av Villor : Finns möjligheten till Passivhusstandard för befintliga bostäder

The climate change the earth today has to face is no longer a global problem when every individual has a responsibility to act. The residents in Sweden have no understanding how their energy consumption affects the environment, nor what measures can be taken to reduce the energy consumption.The use of the energy in new Buildings is considerably lower than in the older ones as conditions have improved and the requirements have been more stringent. As most of the buildings in the future have already been constructed it´s important to take every opportunity for energy efficiency and rebuilding of available buildings will become a significant act. Reconstruction of a building contributes generally to both a reduced individual and a reduced total energy use, while new constructions only keep a low individual energy use but a increase the total energy use. For this reason we present the opportunities for reconstruction, mainly to reach the standards for a passive house..

Kommunicerbara Informationssystem

Nowadays naval units are participating in international missions, where new and in many cases tougher conditions will affect their propulsion. This essay deals with some of the now developed nanostructure coatings and gives a presentation of how the coatings could function on some exposed parts of the naval powertrain. The essay investigates the possibility that the coatings can be used as a protective layer that will reduce or prevent wear on selected parts of the naval powertrains. As a basis for the essay, nanotechnology is described, as well as different reasons that wear occurs and application techniques for coatings The conclusion is that nanostructured coatings can be applied and provide a much better result on hardness and wear resistance as of naval powertrains compared to micro-structural coatings, both for manufacturing and renovation. The essay presents a few examples of the military utility of the nanostructure coatings as well as suggestions for further research..

Dans och språkutveckling i förskolan : En intervjustudie om Reggio Emilia-pedagogers syn på och arbete med dans som språkfrämjande medel

The goal and purpose of this essay is to study if and how multimodality is used within a Swedish school in Kalmar. This is accomplished by observing the different modalities inside the classroom and how the use of different modalities affects the teaching. Unstructured observations combined with a material-based thematic presentation leads up to an analysis based on social semiotics and multimodality. The essay shows how the teaching uses lots of modalities: sound, images, movies, speeches and literary text in lots of different ways. These different types of modalities are used in a multimodal context, providing good conditions for learning..

Gallringsprioritering av contortabestånd :

Extensive planting of the tree species lodgepole pine (Pinus contorta var. latifolia) during the 1970s and 80s has resulted in large areas now being available for commercial thinning. However, the varying quality of the stands creates a problem. The purpose of this study was to investigate, at the Torsby district of the Stora Enso forest company, how well the present computer records of the stands correspond to reality and determine which stands are, from a qualitative perspective, suited for timber production. Finding variables that indicate better stands would give Stora Enso the possibility of selecting qualitative stands which are more profitable to thin. The study included 32 stands containing at least 70 % Pinus contorta.

Verifiering av Kedertakstolen

The Kedertruss is the loadbearing part in the Keder weatherprotectionsystem and it has been analyzed concerning its loadbearing capacity. The Kedertruss is produced and manufactured by Wilhelm Layher GmbH & Co. KG and this report has been made for their Swedish division Layher AB.  The Kedertruss, designed in Germany according to German designcode, has been recalculated concerning Swedish conditions according to Eurocodes and a ongoing European standardization project. The two-dimensional program Winstatik Frame Analysis has been used for evaluation of load effects. Capacity has been calculated by hand-calculations and it has been verified that the Kedertruss in its larger spans isn?t able to withstand the loads.

En studie om vad som motiverar expats att stanna i företag

A flat organisation makes a horizontal career development possible, which means that it is more important to develop an individual?s knowledge base than to gain a higher title. This leads to a personal development, which motivates expats to stay. Since the responsibility of the career development mostly lies on expats themselves, companies should create conditions that make individual, internal job search possible. Like in IKEA:s case, it can be done through a strong and prestige less company culture, that penetrates the whole company.

Tankar om ett kök

The kitchen is one of the most important rooms in our homes. It is a place for social engagements, meetings between people and activity. How the kitchen looks today is a concept sprung from the Swedish kitchen standard of 1952. Eventhou this standard no longer exists it is a model of how kitchens are designed today. The kitchens most often sold today come from one of four major kitchen manufacturers in Sweden.My thesis investiges an alternative kitchen concept.

Synen på det egna ledarskapet : En jämförelse mellan ledare inom skola och vård

AbstractThis essay contains a comparison between principals and supervisors within the Health-care and is focused on their view regarding their own leadership. It contains a comparison between their respective models for leadership and how to evolve as a leader within these two organizations.The study is carried out as in dept interviews with four principals and four supervisors.The results show that the principals have a sufficient education and a broad network, but they need the opportunity to a personal development within their leadership. On the other hand, within the Health-care, the supervisors stand on a good base of education where focus lies on the personal development within the leadership. However, they need more opportunities to build up their networks.The conclusion that can be drawn is that these two organisations would gain on learning from each other, in order to establish as good conditions as possible to improve the leaderships within their own organization..

Kan en heterosexuell man ha feministiskt sex? En studie av villkoren för mänskligt handlande.

SammanfattningSyftet med denna uppsats är att söka svar på vilka analytiska verktyg som krävs för att förstå villkoren för mänskligt handlande. Min tes är att den diskursteoretiska epistemologi som kommit att dominera samtida feministisk forskning - i uppsatsen representerad främst av Judith Butler - inte tillhandahåller dessa analytiska verktyg. För att pröva denna tes har jag intervjuat fem heterosexuella, feministiska män om deras erfarenheter av sex. Jag frågar mig: på vilket sätt bestäms intervjupersonernas sexuella interaktion med kvinnor av deras respektive positioner som heterosexuella män och som feminister? I min analys tillämpar jag ett dialektiskt angreppssätt och stöder mig framför allt på Margaret Archers teoribygge.Min slutsats blir att det, för att i detalj kunna blottlägga villkoren för männens handlande, är fundamentalt att göra den typ av distinktioner som diskursteorin emotsätter sig - mellan subjektivt och objektivt, diskurs och praktik, etcetera.

Mean value modelling of a poppet valve EGR-system

Because of new emission and on board diagnostics legislations, heavy truck manufacturers are facing new challenges when it comes to improving the engines and the control software. Accurate and real time executable engine models are essential in this work. One successful way of lowering the NOx emissions is to use Exhaust Gas Recirculation (EGR). The objective of this thesis is to create a mean value model for Scania's next generation EGR system consisting of a poppet valve and a two stage cooler. The model will be used to extend an existing mean value engine model.

?Tillvaron [...] vidgar sig? : Alberte ? en Ny kvinna i genusomskapandets tid

This essay examines the Alberte triology, by the Norwegian writer Cora Sandel, from a gender/feminist perspective. Taking Yvonne Hirdman's theory about the gender system as a starting point I will show how the living conditions and the different roles of men and women are represented in the novel and how they are changing during the centuries before and after the First World War.I am particularly interested in Alberte, the main character, what attitude she takes to her position in the gender system and in what way she differs from the traditional female model. Is she a New Woman, a different ?species?, who doesn't fit into the rigid gender system? Does the New Woman have a male counterpart, and is he to be found in the novel? Does the novel give a positive vision of a future where men and women can meet as equals?.
