This thesis studies settlement continuity on Gotland between approximately AD 200 and AD 1700. The method used is to calculate correlation between the geographical distribution of all known Iron Age stone-wall-houses (on Gotland known as "kämpagravar") and all farms included in the detailed taxation maps from approximately 1700. The number of remaining house foundations is between 1800 and 1900. A model to estimate the number of removed foundations is presented. It is based on the assumption that the settlement density was proportional to land use around 1700, and that the rate of removal is related to the current land use.

Alla patienter som genomgår någon typ av operation där man penetrerar huden har en ökad risk att drabbas av en postoperativ sårinfektion. Syftet var att utforska de preoperativa åtgärderna huddesinfektion och hårborttagning relaterat till uppkomsten av postoperativa sårinfektioner. Metoden var en systematisk litteratur studie där nio artiklar användes som underlag. Resultatet visade att klorhexidin reducerar bakterierna på huden, men ingen signifikant minskning av antalet postoperativa sårinfektioner kunde påvisas. Av hårborttagningsmetoderna rakhyvel, rakapparat och hårborttagningskräm ger rakhyvel upphov till fler små sår..

In the production of pulp, paper and cardboard, a large amount of water is used daily. The water has to be purified in the internal purifying plant before it reaches the receiving body of water. In the biological purifying stage at the Stora Enso Skoghall mill, an aerated basin is used where the microorganisms, using oxygen, oxidize the organic material to carbon dioxide. The air is pumped from the bottom of the basin and the oxygen can then be transported from the air bubbles to the water through diffusion. The problem with aeration of waste water from the forest industry is that wood residues, such as fatty acids, are making the transport of oxygen in water more difficult.

SammanfattningSyfte och frågeställningarSyftet med studien är att utvärdera hur en fotbollstränare i en ungdomsakademi bedriver fotbollsträning utifrån de teoretiska ramverken Teaching Games for Understanding (TGfU) och Enhanced Guided Discovery (EGD) i syfte att skapa effektivisering i lärande samt starkare självbestämmande motivation. Detta leder till följande frågeställningar:* Hur stor del av träningar med syfte att utveckla spelförståelse, taktik och teknik ägnas åt övningar som är isolerade respektive funktionella?* Hur stor del av träningstiden ägnas åt paus/samling och effektiv träningstid?* Är tränarens arbetssätt präglat av EGD vid inlärning av spelförståelse och teknik?Metod I studien medverkar en tränare för ett akademilag i fotboll. Denne har observerats utifrån den svenska versionen av CAIS (Coaches Analysis Intervention System). CAIS har modifierats utifrån Stenling (2013).

This study is an analysis of a survey that harvester operators working for SCA Ångermanland Skogsförvaltning have been participating in. The purpose of this study is to try to show the harvester operators opinion about the forestry planning that SCA provides. Hopefully will this information lead to suggestion about what part of the forestry planning needs to be improved, if any is needed? Unfortunately only 30 / 60 questionnaire has been returned so no conclusion can be made, except about those who have answered the survey. The answers of the survey indicate a number of areas that needs to be improved. The marked routes needs to be more visible and the education about timber landings must be enhanced.

Every year about 210 000 tones dry weight of sewage sludge is produced in Sweden. Most of the sludge is applied to agricultural land, plantsoil and landfill cover. Sewage sludge contains essential nutrients such as nitrogen and phosphorus. Nitrogen is limiting growth on solid ground in Sweden and can therefore be used as fertilizer to increase productivity. In order that the sludge can be spread to forest land it requires first a conversion of sludge to pellets, to make it more manageable.

Certain microbial residents from composts are known to possess the ability to suppress soilborne plant pathogens. Trichoderma spp. and Gliocladium spp. are commonly found in composts and are perhaps the most wellknown hyperparasites of fungal pathogens, which may also be naturally present in compost. Trials have many times proven them to be effective against plant diseases caused by soilborne pathogens such as Pythium spp., Phytophthora spp.

Barley is one of the most important cereals cultivated in the Nordic countries. Climate change brings warmer and moisture climate which favors fungal diseases. In the cropland barley can be seriously infested with hard fungus attack. Since it is important that the yield bears a high quality it is of great importance to find varieties more resistant to attacks.Pathogenesis-related (PR) proteins are stress proteins induced in the plant in response to infection and abiotic stress (van Loon, 1997). PRs are shown to have antimicrobial activity differing between bacteria, fungi and oomycetes (Tandrup Poulsen, 2001).

The aim of this project was to develop a product which gives one or more objects of daily use an additional function. Thru the creativity of children the object shall transform into a new source for play for pre-school children.The purpose of this work was to research how fantasy and free play of children could be enhanced. I wanted to know how I can motivate children to use their fantasy transforming objects into new sources for play.This was achieved by means of developing a number of different prototypes which I tested in Kindergarden. My observations lead to the development of a cloth-wrap for the chair which provides the required source for ongoing role-play. The chair suddenly transforms into a new landscape and multi-purpose object where children?s fantasy is stimulated and creative play is supported..

This work examines the students´ thoughts on climate change with a focus on carbondioxid through photosynthesis and the carbon emissions from cars. The study is based on two subject areas, one with a focus on enhanced greenhouse effect, and the other focusing on photosythesis. The survey was conducted by means of qualitative interviews with students in grades four and six. The results describe that student´s understanding for photosynthesis and the carbondioxids function for photosynthesis doesn´t change significantly from grade four to grade six. I have divided the students inte three levels based on their understandingof the various fields, and their use of adequate concepts.

The purpose of this essay was to examine how professional social workers work with follow up foster home placements. The study was based on qualitative interviews with ten professional social workers from different municipalities in Skåne in an attempt to answer the following questions:* What routines exist for the follow-up work with foster care?* What factors have an impact on how the follow-up is formed in the particular case?* How can the follow-up affect outcomes of the placement?* In what way could the work with follow-up foster home placements develop?The theories we chose to analyze our material from was the ecology of human development formed by Urie Bronfenbrenner and the theory of civil courage formed by Lennart Lundquist. The interviews were semi-structural which gave the respondents a chance to talk in a free way about the questions we presented.The result of the study showed that there is a difference in the way social workers form the follow-up work of foster care. The greatest difference is in whom the social workers include in their follow-up.

Abstract The purpose of this work is to investigate children?s perception of Swedish birds. Through qualitative questions there were twelve children interviewed. I showed the pictures for the children of different animals that we discussed but with focus on birds. The children could partly distinguish which of the pictures that represented birds and who did not.

The thesis examines how sex/gender and sexuality are represented through text and images within the Internet community Sylvia whose primary target group is girls. Through an examination of the aesthetics, the member rules and the choices that constitute the framework for the site, the study observes Sylvia as a cultural context. In relation to this setting, the ten most visited member profiles at the time for the study are more closely examined. These profiles are studied from a constructivist view of sex/gender and are analysed from the perspective of feminist and quee r theory as well as in the light of feministic debates concerning sexuality and erotica. The thesis shows how Internet as a forum and the non-heterosexual context Sylvia open up for a constructivist understanding of sex/gender and also leads to a questioning of "masculinity" and "femininity".
